In some embodiments, the flip frame 130 may also be divided into two parts arranged symmetrically, for example, two I-shaped, L-shaped, or U-shaped frames separated from each other. The two parts can be respectively disposed on the two lifting frames 120, and each has a turning driving mechanism 150 that drives the turning to control the turning of the two parts simultaneously. These two parts may each have at least one first fixing member 140.

(Or other core making machine components to be cleaned). Correspondingly, the structure and size of the lifting frame 120 can also be set to be suitable for the lifting frame 120 to drive the turning frame 130 to move up and down.

The turning drive mechanism 150 can drive the turning frame 130 to rotate at a preset angle along a horizontal rotation axis through a transmission structure (eg, screw, gear, belt, etc.) (eg, as shown in FIGS. 5 and 6). The preset angle can be set or adjusted by the core making machine control part 181 of the core making machine 180. For example, the turning drive mechanism 150 can be controlled by the control unit to drive the turning frame 130 to rotate any angle in a clockwise direction (direction 122) or a counterclockwise direction (reverse direction of direction 122), and the rotation angle range can be [-360, +360] (The angle shown in Fig. 2 is 0), where-represents rotation in a counterclockwise direction, and + represents rotation in a clockwise direction. In some embodiments, the preset angle can also be adjusted mechanically by a limit assembly (not shown) on the maintenance device 100. In some embodiments, the preset angle may not be adjustable.

In some embodiments, the above-mentioned rotation angle range may be [-180, +180]. In some embodiments, the aforementioned angular range may be [-90, +90]. In some embodiments, the aforementioned angular range may be [0, +180]. In some embodiments, the aforementioned angular range may be [0, +90].

A pair of first fixing members 140 arranged oppositely can fix the upper core box between the two, so that the upper core box can be fixed on the turning frame 130. The first fixing member 140 may have any structure for fixing the upper core box on the flip frame 130. The pair of opposing first fixing members 140 may have the same or different structures.

In some embodiments, at least one of the pair of opposing first fixing members 140 may have a retractable structure. By controlling the expansion and contraction of the retractable structure, the upper core box can be fixed on the flip frame 130 or released from the flip frame 130. In some embodiments, more pairs of first fixing members 140 may be provided on the flip frame 130 to improve the fixing effect of the upper core box. For example, two pairs of first fixing members 140 are shown in FIGS.

In some embodiments, at least one of the pair of opposing first fixing members 140 may have a limiting structure. The limiting structure may have a structure on the upper core box that is substantially complementary to the surface structure that it contacts, thereby improving the stability of fixing the upper core box. For example, the position on the upper core box to be in contact with the first fixing member 140 may include a concave structure (or a structure of other shapes), and the limiting structure on the first fixing member 140 may have a structure complementary to the concave structure ( Or complementary structures of other shapes). When the upper core box is fixed between the pair of first fixing members 140, the convex structure can enter the concave structure, and then the above-mentioned retractable structure can be controlled to extend to fix the upper core box on the turning frame. The above-mentioned limiting structure can improve the stability of the upper core box fixing, and prevent the accident that the upper core box accidentally slips off during the rotation of the flip frame 130.

In some embodiments, the above-mentioned limiting structure may be a part of the above-mentioned retractable structure. For example, the two sides of the upper core box may include symmetrically arranged hole structures, and the corresponding retractable structure of the first fixing member 140 may have a shape complementary to the hole structure. When the upper core box is fixed, the retractable structure of the pair of first fixing members can extend into the hole structure, thereby playing a role of fixing or limiting.

In some embodiments, the first fixing member 140 may fix the core box in the manner shown in FIGS. 3 and 4.

The lifting driving mechanism 150, the turning driving mechanism 160 and other driving mechanisms involved in this application may have any structure or use any driving form, for example, the lifting driving mechanism 150, the turning driving mechanism 160, or other driving mechanisms may be electric drive, liquid Drive, pneumatic drive, etc. In some embodiments, the lifting driving mechanism 150 and the turning driving mechanism 160 may be motors, oil cylinders, or the like.

The maintenance device 100 may include a control signal receiving mechanism 170 for receiving a control signal (for example, a third control signal) from the core making machine control part 181. The control signal receiving structure 170 may be located at any position of the maintenance device 100, such as the bracket 110. In response to the control signal from the core making machine control section 181, the control signal signal receiving mechanism 170 may send the first fixing signal to the first fixing member 140, send the ascending signal to the lifting driving mechanism 150, and send the turning to the turning driving mechanism 160 signal. In response to the first fixing signal, the first fixing member 140 may fix the upper core box transported from the inside of the core making machine to the turning frame 130. In response to the ascending signal, the elevating driving mechanism 150 can drive the elevating rack 120 to drive the reversing rack 130 and the upper core box to ascend. In response to the turning signal, the turning driving mechanism 160 can drive the turning frame 130 to drive the upper core box to rotate along the horizontal rotation axis.

In some embodiments, the above-mentioned ascent signal may include information representing the ascent height, and the elevating driving mechanism 150 may control the elevating frame 120 to ascend the ascent height from its initial position. In some embodiments, the above flip signal may include information representing a rotation angle and / or a rotation direction (for example, clockwise, counterclockwise, etc.), and the flip driving mechanism 160 may control the flip frame 130 to rotate the rotation angle from its initial angle and / Or rotate according to the direction of rotation. It should be noted that the ascent signal and the flip signal may not include information representing ascent height, rotation angle, or rotation direction. For example, the rising height of the lifting frame 120 or the turning angle of the turning frame 130 can be controlled by setting the length of time for sending the rising signal or the turning signal or by setting the mechanical structure for limiting.

In some embodiments, the control signal sent by the core making machine control part 181 to the signal receiving mechanism 170 may include the above-mentioned first fixed signal, rising signal, and flip signal, or a combination thereof. The signal receiving mechanism 170 may only serve as a signal receiving port for each component of the maintenance device 100. For example, the signal receiving mechanism 170 may generate the first fixed signal for the first fixing member 140, the lifting driving mechanism 150, and the receiving port core making machine control portion 181 of the turning driving mechanism 160 by executing program codes and parameters related to maintenance operations , Rising signal, flip signal and other related signals (if any). When the signal receiving mechanism 170 receives the above signal in a wired or wireless manner, it will separately send it to the corresponding structure. In some embodiments, the signal receiving mechanism 170 may also enhance and / or filter the above signals.

In some embodiments, the control signal sent by the core making machine control section 181 to the signal receiving mechanism 170 may only be a trigger signal for maintenance operations. For example, the signal receiving mechanism 170 may include a control circuit, and the first fixed signal, the rising signal, and the flip signal are generated by the control circuit in response to the trigger signal, and sent by the control circuit to the corresponding mechanism, respectively. In some embodiments, the trigger signal may include parameter information (eg, ascent height, flip angle, etc.) for generating the first fixed signal, the up signal, and the flip signal, and the control circuit of the signal receiving mechanism 170 may be based on The parameter information generates the corresponding signal. In some embodiments, the above control circuit may be a central processing unit (CPU), an application specific integrated circuit (ASIC), an application specific instruction set processor (ASIP), a physical processing unit (PPU), a digital signal processor (DSP), a field Programmable gate array (FPGA), programmable logic device (PLD), etc., or any combination thereof.

When the upper core box is fixed on the turning frame 130 by the first fixing member 140, its working surface (inner surface) may be downward. In order to facilitate the cleaning of the exhaust plug (or other parts to be cleaned) of its working surface, the turning frame 130 can be driven to rotate or turn over by the turning drive mechanism 150 so that the working surface (or part to be cleaned) of the upper core box faces the cleaning side In order to clean the upper core box.

In some embodiments, the exhaust plug on the working surface of the upper core box may be manually cleaned. Therefore, the flip frame 130 can be driven to rotate the upper core box, so that the working surface of the upper core box faces the user (for example, a cleaning person) on the cleaning side, so as to facilitate the cleaning of the exhaust plug on the working surface of the upper core box.

In some embodiments, the maintenance device 100 may further include a controller (not shown) for a user (for example, a cleaning person) to adjust the lifting height of the lifting frame 120 and / or the rotation angle of the turning frame 130 to facilitate the user in cleaning Adjust the height and orientation of the upper core box as needed during the upper core box process to improve the cleaning effect. For example, the controller may include buttons, touch screens, joysticks, etc. to facilitate user operations.

In some embodiments, the exhaust plug on the working surface of the upper core box can be passed through a special cleaning mechanism (eg, brush, spray head (eg, dry ice spray head, air spray head), negative pressure tap (eg, for sucking sand debris ), Scrapers, robotic arms, robots, etc.) for cleaning. Therefore, the flip frame 130 can be driven to rotate the upper core box so that the working surface of the upper core box faces the cleaning mechanism, so as to facilitate the cleaning of the exhaust plug on the working surface of the upper core box.

In some embodiments, the cleaning mechanism described above may be included in the maintenance device 100. Accordingly, in response to the control signal of the core making machine control section 181, the control signal receiving mechanism 170 sends a cleaning signal to the cleaning mechanism, causing the cleaning mechanism to cooperate with the lifting and rotation of the upper core box to clean the upper core box. For example, the core making machine control section 181 can simultaneously control the cleaning trajectory, cleaning angle, cleaning force, and corresponding height and orientation of the portion of the upper core box to be cleaned, so that the cleaning mechanism can be at a more appropriate angle, position, and / Or forcefully clean the upper core box to improve the cleaning effect of the upper core box.

In some embodiments, the cleaning mechanism described above may be independent of the maintenance device 100 and directly receive the control of the core making machine control part 181. The core making machine control unit 181 may send control signals to the maintenance device 100 and the cleaning mechanism in a wired or wireless manner, respectively, so that the two cooperate to perform on-site cleaning.

In some embodiments, the exhaust plug on the outer surface of the upper core box can also be cleaned by a similar method.

In some embodiments, the signal receiving mechanism 170 may receive the control signal from the core making machine control part 181 through a cable. The above cable may be pluggable or non-pluggable. For example, in order to facilitate maintenance of the maintenance device 100, the core making machine, and replacement of the maintenance device 100 with other functional modules, etc., the maintenance device 100 may be detachably mounted on the core making machine. The above-mentioned cable may be pluggable to facilitate removal or installation of the maintenance device 100. For example, the aforementioned cable may be inserted into a corresponding control port on the core making machine. The control port may be a port dedicated for controlling the maintenance device 100, or a standardized port for controlling any optional module of the core making machine. Alternatively, the cable can be inserted into the network port of the wired network, and the core making machine can also be connected to the wired network, and the signal receiving mechanism 170 can receive the control signal from the core making machine through the wired network.

In some embodiments, the signal receiving mechanism 170 may receive control signals from the core-making machine control part 181 through a wireless network (eg, WIFI, cellular network, Bluetooth, NFC, etc.), thereby reducing the number of cables and further facilitating disassembly Or install and maintain the device 100.

In some embodiments, the maintenance device 100 may also obtain its components (for example, the first fixing member 140, the elevating driving mechanism 150, the turning driving mechanism 160, from the core machine energy department (for example, electrical box) of the core machine The signal receiving mechanism 170) requires energy (for example, electric energy). The energy source of the core making machine can supply energy to various components of the core making machine, and can include an energy supply port for supplying energy to the maintenance device 100. The maintenance device 100 may include an energy acquisition module (not shown) for acquiring energy required by the various components of the maintenance device 100 from the energy supply port of the energy source part of the core making machine described above.

In some embodiments, the above energy acquisition module may be integrated into the signal receiving mechanism 170, thereby facilitating the disassembly and installation of the maintenance device 100.

In some embodiments, in addition to cleaning the upper core box, the maintenance device 100 can also be used to clean the sandblasting plate of the core making machine (for example, the sandblasting plate 740 shown in FIG. 7). In these embodiments, the maintenance device 100 may further include a second fixing member (for example, the second fixing member 710 shown in FIG. 7) for fixing the sandblasting board. Correspondingly, in response to the control signal of the core making machine control part 181, the signal receiving mechanism 170 can send a second fixing signal to the second fixing member, so that the second fixing member fixes the shot blasting board delivered from the core making machine to the flip 130 on the shelf. In a manner similar to the above method for cleaning the upper core box, it is possible to clean the grit clogged in the sand-blasting holes on the sand-blasting plate.

According to different application scenarios, the maintenance device 100 may have only the first fixing member, only the second fixing member, or both the first fixing member and the second fixing member. The maintenance device 100 may include other types of fixing members for fixing the corresponding types of components to be cleaned (for example, the lower core box, etc.) in the core making machine on the turning frame 130.

In some embodiments, the first fixing member 140, the second fixing member, or other fixing members may be detachably installed on the turning frame 130, so that the corresponding type of fixing member can be selected and installed according to the core making machine component to be cleaned . In some embodiments, the flip frame 130 may include ports for physical connection and / or communication connection with various types of fixing members. Each of the above ports may be dedicated to a specific fixing member, or may be connected to a different fixing member.

In some embodiments, in response to the control signal from the core making machine control portion 181, the control signal receiving mechanism 170 may send an initialization signal to the lift driving mechanism 150 before sending the first fixing signal to the first fixing member 140. The initialization signal may be included in the above control signal or generated by the signal receiving mechanism 170 in response to the control signal. In response to the initialization signal, the elevating drive mechanism 150 can drive the elevating frame 120 to move the flip frame 130 (up or down) to facilitate the first fixing member (or the second fixing member) to fix the upper core box (or sand board) . If the default position of the flip frame 130 is a position that is convenient for the first fixing member (or the second fixing member) to fix the core box (or sand-blasting board), the initialization signal may not be sent.

In some embodiments, in response to a control signal from the core making machine control part 181, or after the maintenance operation is completed, the control signal receiving mechanism 170 may send a reset signal to the flip driving mechanism 160, and send a first signal to the lifting driving mechanism 150 Down signal, and send a first release signal to the first fixture 140. In response to the reset signal, the turning drive mechanism 160 can drive the turning frame 130 to drive the upper core box to rotate along the horizontal rotation axis, and make the working surface of the upper core box face down. In response to the first lowering signal, the elevating driving mechanism 150 can drive the elevating rack 120 to drive the turning frame 130 and the upper core box to a suitable position for releasing the upper core box. In response to the first release signal, the first fixing member 140 may release the upper core box. The released upper core box can be automatically transported back and installed inside the core making machine. If the sandblasting board (or other core making machine component) is cleaned, the control signal receiving mechanism 170 may send a reset signal to the flip driving mechanism 160 and a first descent signal to the lifting driving mechanism 150, and then to the second fixed The device sends a second release signal. In response to the second release signal, the second fixing member (or corresponding other fixing member) may release the sandblasting board. The released blasting board can be automatically transported back and installed inside the core making machine.

In some embodiments, the bracket 110 may also be pivotally connected to the frame, casing, or base or upright of the core making machine so that the bracket 110 can rotate along the vertical rotation axis. The rotation of the bracket 110 along the vertical rotation axis may be driven by a bracket rotation driving mechanism (not shown). Correspondingly, in response to the control signal of the core making machine control part 181, the signal receiving mechanism 170 may send a rack rotation signal to the above-mentioned rack rotation driving mechanism, so that the rack rotation driving mechanism drives the bracket 110 to drive the flip frame 130 and be fixed to the flip frame 130 The upper core box (or sand blasting board, etc.) on the top rotates along the vertical rotation axis, so that the cleaning side does not need to face the core making machine side, thereby further improving the flexibility of cleaning.

In some embodiments, the previously described controller can also be used to adjust the rotation angle of the rack.

In some embodiments, the maintenance device 100 may further include more optional structures. For example, the maintenance transposition may further include a first conveying mechanism (for example, the first conveying mechanism 874 shown in FIG. 8) for cooperating with the second conveying mechanism located inside the core making machine to transfer the upper core box (or Sand board) is conveyed from the inside of the core making machine to the maintenance device 100. Correspondingly, in response to the control signal of the core making machine control part 181, the signal receiving mechanism 170 may send a conveying signal to the first conveying mechanism, so that the first conveying mechanism cooperates with the second conveying mechanism to remove the upper core box (or sand board) from the The core making machine is internally transported to the maintenance device 100, and is further moved to a position where the first fixing member (or the second fixing member) is convenient for fixing the upper core box or the sand-blasting board. After the cleaning is completed, the signal receiving mechanism 170 may also send another conveying signal to the first conveying mechanism, causing the first conveying mechanism to cooperate with the second conveying mechanism to convey the upper core box (or sandblasting board) from the maintenance device 100 back to the core Inside the machine.

It should be noted that FIGS. 1 and 2 are provided for illustrative purposes only, and are not intended to limit the present invention. The structure shown in Figures 1 and 2 can be modified and revised. The number, appearance, and relative positions of the components of the maintenance device 100 (for example, the bracket 110, the lifting frame 120, the turning frame 130, the first fixing member 140, the lifting driving mechanism 150, and the turning driving mechanism 160) are also for illustration only, and It may not accurately reflect its true state in actual use.

3 and 4 are schematic diagrams of the first fixing member fixing the upper core box according to some embodiments of the present invention. Among them, FIG. 3 is a front view, and FIG. 4 is a side view. The

first fixing members

310 and 320 may be an exemplary embodiment of the first fixing member 140, and may have the same or similar structures. The

first fixing members

310 and 320 may be a pair of opposed first fixing members, and are installed on the flip frame 130.

In some embodiments, for example, as shown in FIG. 4, the flip frame 130 may further include a first fixing member 330 (optional), which is located on the same side of the flip frame 130 as the first fixing member 310. The first fixing member 330 may have the same or different structure as the first fixing member 310. The side of the turning frame 130 where the first fixing member 320 is located may further include another first fixing member (not shown in the figure) disposed opposite to the first fixing member 330. In some embodiments, the turning frame 130 may further include more first fixing members.

The outer side of the upper core box 330 may include

protrusions

331 and 332 for fixing the upper core box 330 on the turnover frame 130 in cooperation with the first fixing

members

310 and 320, respectively. The bump 331 may further include a limit block 352. Taking the first fixing member 310 as an example, the first fixing member 310 may include an upper clamping plate 311 and a lower clamping plate 312. The upper clamping plate 311 may include a limiting groove 351 matching the limiting block 352. The lower splint 312 may be a retractable mechanism. The first fixing member 310 may include a driving mechanism 313 to control the expansion and contraction of the lower clamping plate 312. After the limiting block 352 enters the limiting slot 351, the driving mechanism 313 can control the lower clamping plate 312 to extend, so that the convex block 331 can be locked between the upper clamping plate 311 and the lower clamping plate 312.

In some embodiments, the limiting block 352 may be located on the upper clamping plate 311, and the limiting groove 351 may be located on the protrusion 311.

In some embodiments, in order to allow the limit block 352 to enter the limit slot 351, the flip frame 130 or the first fixing member 310 may include driving the upper clamping plate 311 or the entire first fixing member 310 to move horizontally (for example, along the direction 318) Drive mechanism (not shown). Alternatively, the limiting block 352 may enter the limiting groove 351 by lowering the lifting frame 120.

In a similar manner, the first fixing member 320 and other similar first fixing members (if any) can clamp the corresponding protrusions, thereby fixing the upper core box 330 on the turning frame 130. Through the reverse process of fixing the upper core box 330 on the flip frame 130, the upper core box 330 can be released from the flip frame 130, so that it is transported and installed inside the core core machine. In some embodiments, the

protrusions

331 and 332 are also used to fix the upper core box 330 inside the core making machine to perform normal core making operations.

5 and 6 are schematic diagrams showing that the maintenance device (maintenance device 100) shown in FIG. 1 drives the upper core box fixed thereto to rotate according to some embodiments of the present invention. After the upper core box 530 is fixed on the flip frame 130 by the first fixing member 140, the flip frame 130 can be driven by the flip drive mechanism 150 (not shown in FIGS. 5 and 6) to rotate clockwise along the horizontal rotation axis (direction 510) Or rotate counterclockwise (direction 610) by a preset angle. The structure of the fixing member 140 may be the same as or different from the structure of the fixing member 310 (as shown in FIGS. 3 and 4). As shown in FIG. 5, when the flip frame 130 rotates in the clockwise direction, the inner surface (working surface) of the upper core box will face the cleaning side. At this time, the user or cleaning mechanism on the cleaning side can face the inner surface of the upper core box Clean the exhaust plug. As shown in FIG. 6, when the flip frame 130 rotates in the counterclockwise direction, the outer surface of the upper core box will face the cleaning side, and the exhaust plug on the outer surface of the upper core box can be replaced by the user or the cleaning mechanism on the cleaning side Clean up.

7 is a schematic diagram of a maintenance device (maintenance device 700) according to some embodiments of the present invention. The maintenance device 700 is an embodiment of the maintenance device 100, and may have a similar structure to the maintenance device 100. Components with the same reference numbers in FIGS. 1 and 7 may have the same or similar functions and / or structures. The maintenance device 700 can be used for cleaning the upper core box of the core making machine (for example, the upper core box 330), and can also be used for cleaning the sand-blasting plate of the core making machine.

The maintenance device 700 may be controlled by the core making machine control section 781. The core making machine control section 781 is an embodiment of the core making machine control section 181, and further includes a function of controlling the maintenance device 700 to clean the sand-blasting board (for example, the sand-blasting board 740). Compared with the maintenance device 100 shown in FIGS. 1 and 2, the maintenance device 700 further includes a second fixing member 710 for fixing the sand-blasting plate of the core making machine on the turning frame 130. The signal receiving mechanism 770 of the maintenance device 700 is an embodiment of the signal receiving mechanism 170 of the maintenance device 100. In response to the control signal of the core-making machine control section 781, the signal receiving mechanism 770 can send the second fixed signal to the second fixing member 710 in addition to the rising signal, the flip signal, and the first fixed signal to the corresponding structure.

The structure of the first fixing member 140 and / or its installation position on the flip frame 130 can be set according to the structure of the upper core box and its position when it is transported to the maintenance device 700. The structure of the second fixing member 710 and / or its installation position on the turning frame 130 can be set according to the structure of the sandblasting board and its position when it is transported to the maintenance device 700. In some embodiments, the second fixing member 710 may have a structure similar to the first fixing member 310 (for example, including an upper splint, a lower splint, etc.) and may sandwich the shot blasting as shown in FIGS. 4 and 5 board. Since the sandblasting plate and the upper core box have different structures, the size, structure, and / or position of each component of the second fixing member 710 (for example, the upper clamping plate and the lower clamping plate) can be adjusted appropriately.

In some embodiments, the first fixing member 140 and the second fixing member 710 may exist on the flip frame 130 at the same time, but only one type of core-making assembly (upper core box or shooting plate) can be fixed on the maintenance device 700 at the same time. . In these embodiments, the first fixed signal may be different from the second fixed signal, the control signal (for example, the third control signal) for cleaning the upper core box sent by the core making machine control section 781 and for cleaning the sandblasting board Control signals (for example, the fifth control signal) will be different.

In some embodiments, the first fixing member 140 and the second fixing member 710 may be different parts of the same mechanical structure.

In some embodiments, the first fixing member 140 and the second fixing member 710 use the same universal communication interface, and cannot be installed on the turning frame 130 at the same time. The first fixing member 140 or the second fixing member 710 may receive the first fixed signal or the second fixed signal from the signal receiving mechanism 770 using the same data communication link. In these embodiments, the first fixed signal and the second fixed signal may be the same, and the control signal for cleaning the upper core box and the control signal for cleaning the sandblasting board sent by the core making machine control section 781 may also be the same.

In some embodiments, the maintenance device 700 may have only the second fixing member 710. Such a maintenance device 700 may be used only for cleaning of sandblasting boards. Correspondingly, the signal receiving mechanism 770 does not need to send the first fixed signal

After the sandblasting plate is fixed to the flip frame 130, the flipping frame 130 can be driven in a manner similar to that shown in FIGS. 5 and 6 to drive the sandblasting plate fixed thereto in a clockwise direction (for example, direction 510) or reverse The clockwise direction (eg, direction 610) rotates by a certain angle. For example, by driving the turning rack 130 to rotate in a clockwise direction, the sand-blasting holes of the sand-blasting plate can be directed toward the cleaning side, thereby facilitating the cleaning of the residual sand in the sand-blasting holes.

The maintenance device 100 may be fixed on the post 813 (for example, as shown in FIGS. 8, 9, and 10) or the base 814. As shown in FIGS. 9 and 10, along the lateral direction of the core making machine 800 (direction of the crossbeam 812), a first lateral position and a second lateral position can also be provided on both sides of the core making position, respectively.

The upper core box fixing mechanism 882 may be located on the upper core box fixing frame 815 and used to fix the upper core box 880 on the upper core box fixing frame 815 or release the upper core box 880 from the upper core box fixing frame 815. The upper core box fixing frame 815 may be located in the core making position. The core making machine control part 899 can control the upper core box fixing mechanism 882 to fix the upper core box 880 on the upper core box fixing frame 815 for core making operation (for example, as shown in FIG. 10), or control the fixing mechanism 882 to The core box 880 is released from the upper core box fixing frame 815 to perform the maintenance operation (or cleaning operation) of the upper core box 880.

In some embodiments, the upper core box fixing mechanism 882 may have the same or similar structure and fixing mechanism as the first fixing member 140 or the first fixing member 331. For example, the upper core box fixing mechanism 882 may also include a structure similar to the upper clamping plate 311 and the lower clamping plate 312, and clamp the structure similar to the protrusion 331 on the upper core box 880 through the above structure to fix the upper core box 880 Onto the upper core box fixing frame 815.

In some embodiments (eg, as shown in FIGS. 8, 9, and 10), the upper core box fixing frame 815 may be part of the second lifting mechanism 816 (if any). The second lifting mechanism 816 can be used to lift the upper core box fixing frame 815. The core making machine control part 899 may control the driving mechanism (for example, an oil cylinder) of the second lifting mechanism 816, so that the upper core box fixing frame 815 drives the upper core box 880 fixed thereon to move up and down. The second lifting mechanism 816 can be used to fix the upper core box 880 on the upper core box fixing frame 815, release the upper core box 880 from the upper core box fixing frame 815, and mold the upper core box 880 and the lower core box 881 A complete core box is formed for core making, and the upper core box 880 and the lower core box 881 are detached for core taking, etc.

In some embodiments, the upper core box carrying mechanism may be an independent upper core box carrier. The upper core box carrier may include a surface structure suitable for carrying the upper core box 880, so that the working surface of the upper core box is placed down on the upper core box carrier. In some embodiments, the upper core box carrier may include a driving mechanism for driving the upper core box carrier to move. Alternatively, the upper core box carrier may not include a driving mechanism, and the core box transport mechanism 807 may include a mechanism for transporting the upper core box carrier (eg, conveyor belt, roller table, gear set, etc.).

In some embodiments, the core box moving cart 871 and the lower core box 881 fixed on the core box moving cart 871 can be used as the upper core box carrying mechanism, so that there is no need to provide an independent upper core box carrier. The surface structure of the lower core box 881 itself is suitable for the downward placement of the upper core box 880, and the lower core box moving trolley 871 itself is also easy to move. The core box moving cart 871 may be transported by controlling the movement of the core box moving cart 871, or controlling other transport mechanisms in the core box transport mechanism 807. By using the core box moving cart 871 and the lower core box 881 fixed on the core box moving cart 871 as the upper core box carrying mechanism, the structure of the core making machine 800 can be simplified, and its components can be fully utilized for core making operations and maintenance operations.

In some embodiments, the core box transport mechanism 807 may include a guide rail 872 for guiding the movement of the core box moving cart 871 or the upper core box carrier.

And the second conveying mechanism 874 may be an inherent part of the core making machine 800.

In some embodiments, the core box transport mechanism 807 need not include the first transport mechanism 873 and the second transport mechanism 874 as shown in FIG. 8. For example, by extending the guide rail 872, it can guide the core box moving cart 871 to move between the core taking position, the core making position, and the maintenance position.

When in the core making position, the core box moving cart 871 or the upper core box carrier can be on the first sub-rail. The second sub-rail is used to guide the core box moving trolley 871 to move between the first sub-rail and the core taking position. The third sub-rail is used to guide the core box moving trolley 871 or the upper core box carrier to move between the first sub-rail and the maintenance position. The three-stage guide rail structure can facilitate the movement of the core box moving cart 871 or the upper core box carrier between the core making position, the core taking position, and the maintenance position without affecting the lifting of the first lifting mechanism 808.

In some embodiments, when the core box transport mechanism 807 includes the upper core box carrier, the guide rail 872 can guide the core box moving cart 871 to move between the core taking position and the core making position, and guide the upper core box carrier to make Move between core position and maintenance position.

The sandblasting plate 891 may be released onto the upper core box 880 located below it. In some embodiments, the sandblasting plate fixing mechanism may have the same or similar structure and fixing mechanism as the second fixing member 710.

In some embodiments, the sandblasting plate 899 and the shooting head 831 may be integrated, and the integrated structure may also be referred to as sandblasting plate in this application. Correspondingly, the above-mentioned sand-blasting plate fixing mechanism can fix the integrated sand-blasting plate to the sand storage mechanism 803 or release it from the sand storage mechanism 803. The

maintenance device

100 or 700 can also be used for maintenance of such sandblasting boards.

The sand-blasting mechanism 804 may be located at the core making position. The sand-blasting mechanism 804 may include an indenter 841, a catheter 842, and an indenter driving mechanism 844. The indenter driving mechanism 844 (for example, an oil cylinder) may be installed on the upper frame 811 and connected to the indenter 841 through a connecting rod 849.

The inside of the indenter 841 may include a cavity structure.

The air pressure mechanism 805 may be located in the second lateral position. The air pressure mechanism 805 can introduce compressed gas into the cavity structure inside the pressure head 841 through the pipeline 848 and the conduit 843. When the sand storage mechanism 803 is located in the core making position, the core making machine control part 899 can control the above-mentioned cavity structure and the chamber for sand storage in the sand storage mechanism 803 to conduct, thereby using compressed gas to The sand-making raw material is pressed into the core box after the mold clamping through the sand-blasting plate 891.

In some embodiments, the catalytic gas introduction mechanism 806 may further include an upper core mechanism 892 for pushing the prepared sand core away from the upper core box.

The core making machine control unit 899 may be an embodiment of the core making machine control unit 181. The core making machine control unit 899 can be used to control various components of the core making machine 800 to realize various operations, such as core making operations. The core making machine control part 899 may be installed on the frame 801 or the casing of the core making machine 800 or separated from the core making machine 800. The core making machine control unit 899 may control various components of the core making machine 800 in a wired or wireless manner.

In some embodiments, the core making machine control part 899 may also provide an operation interface for the user to operate the core making machine 800 and / or the maintenance device 100. The user can also input various relevant parameters through the operation interface to trigger, control, or monitor core making operations, maintenance operations, or other operations.

In some embodiments, the core making machine control unit 899 may be separated from the core making machine 800, and the core making machine 800 may serve as a transfer station for the core making machine control unit 899 to control the maintenance device 100. For example, all control signals of the core making machine 899 (for controlling the core making machine 800 and the maintenance device 100) may be first received by one or more signal ports on the core making machine 800. The core-making machine 800 may further include a port connected to the maintenance device 100 (or the signal receiving mechanism 170). The control signal received by the core-making machine 800 for controlling the maintenance device 100 through one or more of the above-mentioned signal ports may pass the maintenance The port to which the device 100 (or signal receiving mechanism 170) is connected is provided to the maintenance device 100 (or signal receiving mechanism 170). Since there may be a long distance between the core making machine control part 899 and the signal receiving mechanism 170, by using the core making machine 800 as a relay station, the number of cables exposed to the outside world can be reduced, and the safety can be improved.

In some embodiments, the core making machine control unit 899 may control the core making machine 800 to perform core making operations through the following steps.

Step 1: The core making machine control part 899 controls the sand adding mechanism 802 to add the sand making raw material to the sand storage mechanism 803.

Step 2: The core making machine control unit 899 controls the sand storage mechanism 803 to move from the first lateral position to the core making position. If the catalytic gas introduction mechanism 806 is in the core making position at this time, the catalytic gas introduction mechanism 806 is controlled to move from the core making position to the second lateral position before step 3 is performed, or when the step 3 is executed, the catalytic gas introduction mechanism 806 is controlled from The core making position moves to the second lateral position.

Step 3: The core making machine control unit 899 controls the second lifting mechanism 816 to cause the upper core box fixing frame 815 and the upper core box 880 fixed on the upper core box fixing frame 815 to descend, so that the upper core box 880 and the The lower core box 881 is clamped to form a complete core box. If the lower core box 881 is not located at the core making position, the core making machine control unit 899 may first control the core box conveying mechanism 807 to move the lower core box 881 to the core making position.

Step 4: The core-making machine control unit 899 controls the pressure head 841 of the sand-blasting mechanism 804 to press down, driving the sand storage mechanism 803 to press down, so that the sand-blasting plate 891 presses the upper core box 880. At this time, the sand-blasting port 893 of the sand-blasting plate is inserted into the feed port (not shown) on the upper core box 880.

In some embodiments, step 3 and step 4 may be performed simultaneously. For example, during the process in which the indenter 841 drives the sand storage mechanism 803 to press down, the upper core box fixing frame 815 may be lowered at the same time. The upper core box fixing frame 815 may be driven down by the driving mechanism of the second lifting mechanism, or driven down by the indenter 841.

Step 5: The core making machine control unit 899 controls the compressed gas from the air pressure mechanism 805 through the pipeline 848, the conduit 843, and the indenter 841 to enter the sand storage mechanism, thereby pressing the sand making raw material into the core box (ie, sand shooting) ), The excess gas in the core box can be discharged from the core box through the exhaust plugs (not shown) arranged on the upper and lower core boxes.

Step 6: The core-making machine control unit 899 controls the indenter 841 to drive the sand storage mechanism 803 to rise, so that the sand storage mechanism 803 returns to the cross arm 812.

Step 7: The core making machine control unit 899 controls the sand storage mechanism 803 to move from the core making position to the first lateral position.

Step 8: The core making machine control unit 899 controls the catalytic gas introduction mechanism 806 to move from the second lateral position to the core making position. Wherein, step 7 can be performed before step 8 or synchronized with step 8.

Step 9: The core making machine control unit 899 controls the pressure head 841 of the sand-blasting mechanism 804 to press down, driving the catalytic gas introducing mechanism 806 to press down, so that the catalytic gas introducing mechanism 806 presses the upper core box 880. At this time, the gas outlet (not shown) of the catalytic gas introduction mechanism 806 is inserted into the feed port on the upper core box 880.

Step 10: The core making machine control part 899 controls the catalytic gas introduction mechanism 806 to inject the catalytic gas into the core box to catalyze the curing agent in the raw material for sand making to solidify, so that the sand core is shaped.

Step 11: The core making machine control unit 899 controls the indenter 841 to drive the catalytic gas introduction mechanism 806 up, and returns the catalytic gas introduction mechanism 806 to the cross arm 812.

Step 12: The core making machine control unit 899 controls the second lifting mechanism 816 to cause the upper core box fixing frame 815 to drive the upper core box 880 fixed thereon to separate the upper core box 880 and the lower core box 881. Step 12 may be performed after step 11, or performed in synchronization with step 11.

Step 13: The core making machine control part 899 controls the upper core pushing mechanism 892 to push the sand core away from the upper core box 880, so that the sand core remains in the lower core box 881. In some embodiments, step 13 and step 12 may be performed synchronously.

Step 14: The core making machine control part 889 controls the core box moving carriage 871 to move from the core making position to the core taking position along the guide rail 872.

Step 15: The core making machine control part 889 controls the lower top core mechanism 886 located at the core taking position to push the sand core in the lower core box 881 out of the lower core box. At this time, the core can be taken automatically (for example, by a robotic arm, a robot) or manually. The obtained sand core can be moved to the warehouse for storage, or moved to the downstream production line. In some embodiments, the lower top core mechanism 886 may be integrated into the core box moving cart 871.

By repeatedly performing the above steps 1 to 15, the manufacture of the sand core can be continuously performed. It should be noted that the structure of the core making machine 800 shown in FIGS. 8, 9, and 10 and the core making operation thereof are only examples, and are not intended to be limiting. The specific structure of the core making machine 800 can be changed or adjusted according to the core making process. Some exemplary changes or adjustments are described below.

The above steps 1 to 15 mainly describe the cold core box core making process. In some embodiments, the core making machine 800 can be made by introducing heating components into the core making machine 800 and adjusting the steps and parameters of the related core making operations The sand core is manufactured by the core box making process.

In the above steps 1 to 15, the upper core box 880 is lowered by controlling the second lifting mechanism 816 or the indenter driving mechanism 844, so that the upper core box 880 and the lower core box 881 are closed and the sand making operation is completed. In some embodiments, the first lifting mechanism 808 may be controlled to cause the lower core box 881 to rise to mold the upper core box 880 and the lower core box 881, thereby completing the sand making operation.

For example, steps 3 and 4 can be replaced by steps 3 'and 4'. In step 3 ', the core making machine control part 899 may control the second lifting mechanism 816 to rise, so that the upper core box 880 fixed on the upper core box fixing frame 815 is raised, and the upper core box 880 is pressed against the sand board 891. At this time, the sand-blasting port 893 of the sand-blasting plate is inserted into the feed port on the upper core box 880. In step 4 ', the core making machine control part 899 may control the first lifting mechanism 808 to cause the lower core box 881 located at the core making position to rise, so that the upper core box 880 and the lower core box 881 are clamped to form a complete core box. In some embodiments, steps 3 'and 4' may be performed simultaneously. For example, during a process in which the first lifting mechanism 808 drives the lower core box 881 to rise, the upper core box fixing frame 815 may simultaneously drive the upper core box 880 to rise. Step 6 can be replaced by step 6 '. In step 6 ', the core making machine control unit 899 may control the first elevating mechanism 808 and the second elevating mechanism 816 to descend, so as to facilitate replacing the sand storage mechanism 803 with the catalytic gas introduction mechanism 808 in steps 7 and 8. Similarly, step 11 can be replaced by step 11 '. In step 11 ', the core making machine control unit 899 may control the first elevating mechanism 808 and the second elevating mechanism 816 to descend. Step 12 can be replaced by step 12 '. In step 12 ', after the second elevating mechanism 816 stops descending, the core making machine control section 899 may continue to control the first elevating mechanism 808 to descend back to its original position, so that the upper core box 880 and the lower core box 881 are separated. In some embodiments, step 12 'may be performed in synchronization with step 13.

During the manufacturing process of the sand core, the exhaust plug of the upper core box and the sand-blasting hole of the sand-blasting plate may be blocked. The core making machine control unit 899 can simultaneously control the core making machine 800 and the maintenance device 100 to clean the upper core box 880 and the sand-blasting plate 891. The core making machine control unit 899 may control the maintenance device 100 and related parts of the core making machine 800 to perform maintenance (or cleaning) of the upper core box 880 and the sandblasting plate 891 together. In some embodiments, the core making machine control unit 899 may perform maintenance on the upper core box 880 through the process shown in FIG. 11.

It should be noted that FIGS. 8 to 10 are provided for illustrative purposes only, and are not intended to limit the present invention. The structure shown in FIGS. 8 to 10 can be modified and modified. The number, appearance, and relative positions of the components of the core making machine 800 are also for illustration only, and may not accurately reflect their true state in actual use. For example, in some embodiments, the maintenance position and the coring position may be set on the same side of the core making machine 800 and at different distances from the core making position. Alternatively, the maintenance position and the core position can be combined into one position.

FIG. 11 is a flowchart of a process for automatically maintaining a core box according to some embodiments of the present invention. The core making machine control part 899 of the core making machine 800 shown in FIG. 8 can control the maintenance device 100 and related parts of the core making machine 800 through the flow 1100 to perform maintenance (or cleaning) of the upper core box 880.

FIG. 12 to FIG. 17 are schematic diagrams of the process of automatically maintaining the upper core box shown in FIG. 11 according to some embodiments of the present invention, which are used to explain the relevant steps of the process 1100.

In step 1110, the core making machine control unit 899 may control the upper core box fixing mechanism 822 to release the upper core box 880 on the upper core box carrying mechanism. The upper core box carrying mechanism may be formed by the core box moving trolley 871 and the lower core box 881 fixed thereon, or an independent upper core box carrier as described previously. For example, the core making machine control part 899 may send the first control signal to the upper core box fixing mechanism 882, so that the upper core box fixing mechanism 882 releases the upper core box 880 to the upper core box carrying mechanism. Step 1110 can be carried out after the core removal operation.

In some embodiments, the upper core box carrier mechanism may be an upper core box carrier. Before performing step 1110, the core making machine control unit 899 may first control the core box conveying mechanism 807 to move the upper core box carrier from the maintenance position to the core making position. If the lower core box moving cart 871 is located in the core making position, the core making machine control unit 899 may control the core box conveying mechanism 807 to move the core box moving cart 871 to the core taking position. The moving core box moving car 871 and moving the upper core box carrier can be executed in sequence or synchronously.

In some embodiments, the upper core box carrying mechanism may be formed by a core box moving cart 871 and a lower core box 881 fixed thereon (for example, as shown in FIGS. 12 to 17). After the upper core box 880 is released on the lower core box 881, the upper core box 880 and the lower core box 881 may be closed. Before performing step 1110, the core making machine control part 899 may first control the core box conveying mechanism 807 (for example, by controlling the core box moving trolley 871) to move the lower core box 881 from the core taking position to the core making position (for example, as shown in the figure 12). Then, the core making machine control part 899 can control the second lifting mechanism 816 to lower the upper core box 880 to be close to or close to the lower core box 881, and then perform step 1110 to release the upper core box 880 from the upper core box fixing bracket 815 to The lower core box 881 (for example, as shown in FIG. 13). After performing step 1110, the second lifting mechanism 816 may maintain the lowered state or be returned to the original position under the control of the core making machine control portion 899. The core making machine control part 899 can control the first lifting mechanism 808 to raise the lower core box 880 (together with the core box moving trolley 871) to approach or close to the upper core box 880, and then perform step 1110 to remove the upper core box 880 from the upper core The box fixing frame 815 is released on the lower core box 881, and then the first lifting mechanism 808 is controlled to drive the lower core box 881 and the upper core box 880 down to perform step 1120.

In step 1120, the core making machine control unit 899 may control the core box conveying mechanism 807 to convey the upper core box carrying mechanism together with the upper core box 880 from the core making position to the maintenance position. For example, the core making machine control section 899 may send a second control signal to the core box conveying mechanism 807, so that the upper core box carrying mechanism conveys the upper core box 880 from the core making position to the maintenance position (for example, as shown in FIG. 14).

In some embodiments, the core making machine 800 may not include the first conveying mechanism 874 and the second conveying mechanism 873, the upper core box carrying mechanism may include a driving mechanism to move the upper core box carrying mechanism, and the guide rail 872 is also used to The upper core box carrying mechanism is guided to move between the core making position and the maintenance position. Then, the above second control signal may be received by the driving mechanism of the upper core box carrying mechanism. In response to the second control signal, the driving mechanism of the upper core box carrying mechanism can drive the upper core box carrying mechanism to move along the guide rail 872 toward the maintenance position.

In some embodiments, the core making machine 800 may include a first conveying mechanism 874 and a second conveying mechanism 873 (as shown in FIG. 8), then the second control signal may be received by the first conveying mechanism 874 and the second conveying mechanism 873 . The first conveying mechanism 874 and the second conveying mechanism 873 may be rollers, conveyor belts, or other conveying devices. In response to the second control signal, the first conveying mechanism 874 and the second conveying mechanism 873 may cooperate to convey the upper core box carrying mechanism from the core making position to the maintenance position. For example, the second control signal may cause the first conveying mechanism 874 and the second conveying mechanism 873 to simultaneously convey the upper core box carrying mechanism to the direction of the maintenance position.

Step 1130: The core-making machine control unit 899 can control the lifting driving mechanism 150 to drive the lifting frame 120 up or down, and drive the first fixing member 140 to move to the first fixing position (as shown in FIG. 15). The first fixed position may be a position after the upper core box 880 is transported to the maintenance position. It should be noted that if the initial position of the first fixing member 140 is at the first fixing position, step 1130 may not be performed.

Step 1140: The core-making machine control unit 899 can control the first fixing member 140 (located at the first fixing position) to fix the upper core box 880 on the turnover frame 130. In some embodiments, the first fixing member 140 may have a structure like the first fixing member 311.

Step 1150: The core making machine control unit 899 can control the lifting drive mechanism 150 to drive the lifting frame 120 to drive the flip frame 130 and the upper core box 880 fixed on the flip frame 130 to separate the upper core box 880 and the upper core box carrying mechanism ( For example, as shown in Figure 16). When the upper core box carrying mechanism is formed by the core box moving cart 871 and the lower core box 881, in step 1150, the upper core box 880 may be separated from the lower core box 881, and the lower core box 881 may remain in the core box moving cart 871 in.

Step 1160: The core making machine control part 899 can control the turning drive mechanism 160 to drive the turning frame 130 to drive the upper core box 880 to rotate along the horizontal rotation axis, so that the portion (inner surface or outer surface) of the upper core box 880 to be cleaned faces the cleaning side ( For example, as shown in FIG. 17) to perform subsequent cleaning operations (manually or automatically).

The core making machine control section 899 may send a third control signal to the signal receiving mechanism 170 (or 770) of the maintenance device to perform steps 1130 to 1150. In response to the third control signal, the control signal signal receiving mechanism 170 may send the first preparation signal (optional) to the lifting driving mechanism 150 in sequence, send the first fixing signal to the first fixing member 140, and send to the lifting driving mechanism 150 The rising signal sends a turning signal to the turning drive mechanism 160. In response to the first preparation signal, the elevating drive mechanism 150 may control the elevating drive mechanism 150 to drive the elevating frame 120 up or down to move the first fixing member 140 to the first fixing position. In response to the first fixing signal, the first fixing member 140 may fix the upper core box 880 on the flip frame 130. In response to the ascending signal, the elevating driving mechanism 150 can drive the elevating rack 120 to drive the turning rack 130 and the upper core box 880 to ascend. In response to the flip signal, the flip drive mechanism 160 can drive the flip frame 130 to drive the upper core box 880 to rotate along the horizontal rotation axis.

The above-mentioned first preparation signal (optional), first fixed signal, rising signal, and rollover signal may be included in the third control signal, or the control circuit (if any) of the signal receiving mechanism 170 may respond to the third control The signal is generated.

In some embodiments, the operation interface provided by the core-making machine control part 899 may also be used for a user to input or select a turning angle of the turning frame 130. The core making machine control unit 899 may receive the flip angle input by the user, and cause the third control signal generated by it to include the flip angle information. The core making machine control part 899 sending the third control signal to the maintenance device 100 may cause the turning drive mechanism 160 to drive the turning frame 130 to rotate the turning angle along the horizontal rotation axis from its initial angle (for example, 0 degrees).

In some embodiments, the operation interface provided by the core-making machine control unit 899 may also be used for user input or selection of the lifting height of the lifting frame 120. The core making machine control unit 899 may receive the ascent height input by the user, and cause the third control signal generated by it to include the ascent information. The core making machine control unit 899 sends the third control signal to the maintenance device 100 to cause the lifting driving mechanism 150 to drive the lifting frame 120 to rise from its initial height (for example, the height of the first fixed position) by the rising height.

In some embodiments, the maintenance device 100 may further include a controller (not shown) for a user (for example, a cleaning person) to adjust the lifting height of the lifting frame 120 and / or the rotation angle of the turning frame 130. The controller can be located in the maintenance position, which is convenient for the user to adjust the height and orientation of the upper core box as needed during the process of cleaning the upper core box to improve the cleaning effect. For example, the controller may include buttons, touch screens, joysticks, etc. to facilitate user operations.

Through the above embodiment, it is convenient for the user to freely adjust the height and angle of the upper core box 880 when it is cleaned, thereby improving the cleaning effect.

In some embodiments, in step 1160, the core making machine control unit 899 may also send a sixth control signal to the core box conveying mechanism 807, so that the core box conveying mechanism 807 conveys the lower core box 881 from the maintenance position back to the core making position Or take the core position to facilitate the rotation or cleaning of the upper core box 810. In some embodiments, the core taking position can be set to a mechanism for cleaning the lower core box, and the setting can be controlled by the core making machine control unit 899, so that during the process of cleaning the upper core box (maintenance position is performed) , Clean the lower core box at the core position. Alternatively, the cleaning of the lower core box at the core taking position can also be performed manually.

In some embodiments, after step 1160 is performed, the lower core box 881 may be left in the maintenance position. In the process of cleaning the upper core box, the lower core box 881 may also be cleaned (manually or automatically) at the maintenance position. For example, a mechanism for cleaning and / or rotating the lower core box may be set at the maintenance position, and the mechanism may be controlled by the core making machine control unit 899.

After the cleaning of the upper core box 880 is completed, the core making machine control part 899 may send a seventh control signal to the signal receiving mechanism 170 (or 770). In response to the seventh control signal, the control signal receiving mechanism 170 may sequentially send a reset signal to the flip driving mechanism 160, a first descent signal to the elevating driving mechanism 150, and a first release signal to the first fixing member 140. In response to the reset signal, the turning drive mechanism 160 can drive the turning frame 130 to drive the upper core box to rotate along the horizontal rotation axis, and make the working surface of the upper core box 880 face down. In response to the first lowering signal, the elevating driving mechanism 150 can drive the elevating rack 120 to drive the flip frame 130 and the upper core box 880 to a suitable position (e.g., the first fixed position) for releasing the upper core box 880. In response to the first release signal, the first fixing member 140 may release the upper core box 880 to the upper core box carrying mechanism below. If the upper core box carrying mechanism is transported back to the core making position (or any other position) when step 1160 is executed, before the first release signal is sent, the core making machine control unit 899 may send the first The eight control signals cause the core box conveying mechanism 807 to move the upper core box carrying mechanism back to the maintenance position.

After the upper core box 880 is released from the maintenance device 100, the core making machine control section 899 may send a ninth control signal (which may be the same as or different from the sixth control signal) to the core box conveying mechanism 807, causing the core box conveying mechanism 807 The upper core box carrying mechanism and the upper core box 880 are transported from the maintenance position back to the core making position to install the upper core box 880. For example, the core making machine control unit 899 may control the first lifting mechanism 808 to drive the upper core box carrying mechanism and the upper core box 880 to an appropriate position, and then control the upper core box fixing mechanism 882 to fix the upper core box 880 to the upper core box Then, the first lifting mechanism 808 is controlled to descend to its original position on the fixing frame 815, thereby completing the installation of the upper core box. For another example, the core making machine control unit 899 can control the second lifting mechanism 816 to drive the upper core box fixing frame 815 to a proper position, and then control the upper core box fixing mechanism 882 to fix the upper core box 880 on the upper core box fixing frame 815 Then, the second lifting mechanism 816 is controlled to descend to its original position, thereby completing the installation of the upper core box. After the upper core box is installed, the core making machine 800 may continue the core making operation.

It should be noted that the above description of the process 1100 is for illustrative purposes only, and is not intended to limit the present invention. It can be understood that, after understanding the main concepts and principles of the present invention, a person of ordinary skill in the art may make non-creative modifications to the process 1100. These modifications may include combining and / or splitting certain steps, adding or deleting optional steps, changing the execution order of the steps, and so on. These changes fall within the scope of protection of this application.

FIG. 18 is a flowchart of an automated maintenance process for a shot blasting board according to some embodiments of the present invention. The core making machine control part 899 of the core making machine 800 shown in FIG. 8 can control the maintenance device 700 and related parts of the core making machine 800 through the process 1800 to perform maintenance (or cleaning) of the sandblasting plate 891. The maintenance device 700 may be installed on the core making machine 800 instead of the maintenance device 100.

Step 1810: The core making machine control part 899 can control the upper core box fixing mechanism 822 to release the upper core box 880 on the upper core box carrying mechanism. Step 1810 may be the same as step 1110, so it will not be repeated here.

Step 1820: The core making machine control part 899 can control the sand-blasting plate fixing mechanism of the core-making machine 800 to release the sand-blasting plate 891 on the upper core box 880. The sandblasting plate fixing mechanism may be located on the sand storage mechanism 803, and used to fix the sandblasting plate 891 on the sand storage mechanism 803 or release the sandblasting plate 891 from the sand storage mechanism 803. The core making machine control part 899 may send a fourth control signal to the sandblasting plate fixing mechanism, so that the sandblasting plate fixing mechanism releases the sandblasting plate 891 on the upper core box 880. If the sand storage mechanism 803 is not in the core making position (for example, in the first lateral position), before performing step 1820, the core making machine control section 899 may first control the sand storage mechanism moving mechanism of the core making machine 800 to move the sand storage mechanism 803 Move to the core making position.

In some embodiments, the core making machine control unit 899 may first control the pressure head 841 of the sand-blasting mechanism 804 to be pressed down, and drive the sand storage mechanism 803 to be pressed down, so that the sand-blasting plate 891 approaches or compacts the upper core box 880, The sandblasting plate fixing mechanism is controlled to release the sandblasting plate 891 on the upper core box 880. Alternatively, the core making machine control unit 899 may control the second lifting mechanism 816 to raise, so that the upper core box 880 fixed on the upper core box fixing frame 815 approaches or compresses the sand blasting plate 891, and then control the sand blasting plate fixing mechanism to The sandblasting plate 891 is released on the upper core box 880.

In some embodiments, step 1820 may be performed after step 1810, that is, after the upper core box 880 is first released onto the upper core box carrying mechanism, then the sandblasting plate 891 is released onto the upper core box 880.

In some embodiments, step 1820 may be performed before step 1810, that is, when the upper core box 880 is fixed to the upper core box fixing bracket 815, the sand blasting plate 891 is released on the upper core box 880, and then step 1810 is performed so that The upper core box 880 and the sandblasting plate 891 are released on the lower core box 881 together.

In some embodiments,

steps

1820 and 1810 can be performed simultaneously.

Step 1830: The core making machine control part 899 can control the core box conveying mechanism 807 to convey the upper core box carrying mechanism together with the upper core box 880 and the sandblasting plate 891 from the core making position to the maintenance position. Step 1830 may be the same as step 1120, so it will not be repeated here.

Step 1840: The core-making machine control unit 899 can control the lifting driving mechanism 150 to drive the lifting frame 120 up or down, and drive the second fixing member 710 to move to the second fixing position. The second fixed position may be the position after the sandblasting plate 891 is transported to the maintenance position. It should be noted that if the initial position of the second fixing member 710 is at the second fixing position, step 1840 may not be performed.

Step 1850: The core-making machine control unit 899 can control the second fixing member 710 (located at the second fixing position) to fix the sand-blasting plate 891 on the turning frame 130.

Step 1860: The core making machine control unit 899 can control the lifting driving mechanism 150 to drive the lifting frame 120 to drive the turning frame 130 and the sand-blasting plate 891 fixed on the turning frame 130 to rise, so that the sand-blasting plate 891 and the upper core box 880 are separated. The upper core box 880 may be left in the upper core box carrying mechanism.

Step 1870: The core-making machine control part 899 can control the turning drive mechanism 160 to drive the turning frame 130 to drive the sand-blasting plate 891 to rotate along the horizontal rotation axis, so that the portion (inner or outer surface) of the sand-blasting plate 891 to be cleaned faces the cleaning side ( For example, as shown in FIG. 17) to perform subsequent cleaning operations (manually or automatically).

Steps 1840 to 1870 can be similar to steps 1130 to 1160, respectively. For example, the core making machine control section 899 may send a fifth control signal to the signal receiving mechanism 170 (or 770) of the maintenance device to perform steps 1840 to 1870. In response to the fifth control signal, the control signal signal receiving mechanism 170 may send a second preparation signal (optional) to the lifting driving mechanism 150 in sequence, send a second fixing signal to the second fixing member 710, and send to the lifting driving mechanism 150 The rising signal sends a turning signal to the turning drive mechanism 160. In response to the second preparation signal (which may be the same as or different from the first preparation signal), the lifting driving mechanism 150 may control the lifting driving mechanism 150 to drive the lifting frame 120 up or down to move the second fixing member 140 to the second fixing position. In response to the second fixing signal, the second fixing member 710 may fix the sand-blasting board 891 to the turning frame 130. In response to the ascent signal, the elevating drive mechanism 150 can drive the elevating frame 120 to drive the turning frame 130 and the sand-blasting plate 891 to rise. In response to the turning signal, the turning drive mechanism 160 can drive the turning frame 130 to drive the sand-blasting plate 891 to rotate along the horizontal rotation axis.

The above-mentioned second preparation signal (optional), second fixed signal, rising signal, and rollover signal may be included in the fifth control signal, or the control circuit (if any) of the signal receiving mechanism 770 may respond to the fifth control The signal is generated.

After the cleaning of the sandblasting board 891 is completed, the core making machine control part 899 may send a tenth control signal to the signal receiving mechanism 170 (or 770). In response to the tenth control signal, the control signal receiving mechanism 170 may sequentially send a reset signal to the flip driving mechanism 160, a second descent signal to the elevating driving mechanism 150, and a second release signal to the second fixture 710. In response to the reset signal, the flip driving mechanism 160 can drive the flip frame 130 to drive the upper core box to rotate along the horizontal rotation axis, and make the working surface of the upper core box 880 face down. In response to the second lowering signal, the elevating driving mechanism 150 can drive the elevating rack 120 to drive the turning rack 130 and the sandblasting plate 891 to a suitable position (for example, the second fixed position) for releasing the sandblasting plate 891. In response to the second release signal, the second fixture 710 may release the sandblasting plate 891 onto the upper core box 880 below. If the upper core box 880 and the lower core box 881 are transported back to the core making position (or any other position) when step 1870 is executed, the core making machine control unit 899 can control the core box transport before the second release signal is sent The mechanism 807 moves the upper core box 880 and the upper core box carrying mechanism back to the maintenance position.

After the sandblasting board 891 is released from the maintenance device 100, the core making machine control unit 899 may send a ninth control signal to the core box conveying mechanism 807, so that the core box conveying mechanism 807 will transfer the upper core box carrying mechanism and the upper core box 880 And the sand-blasting plate 891 is transferred from the maintenance position to the core-making position to install the upper core box 880 and the sand-blasting plate 891. For example, in order to install the upper core box 880 and the sand-blasting plate 891, the core-making machine control unit 899 may: control the first lifting mechanism 808 to drive the upper core box carrying mechanism, the upper core box 880, and the sand-blasting plate 891 to a suitable position; Control the upper core box fixing mechanism 882 to fix the upper core box 880 on the upper core box fixing frame 815; control the second lifting mechanism 816 to drive the upper core box fixing frame 815, the upper core box 880, and the sand-blasting plate 891 to a proper position Control the sandblasting plate fixing mechanism to install the sandblasting plate 891 back to the sand storage mechanism 803; control the first lifting mechanism 808 to descend to its initial position; and control the second lifting mechanism to descend to its initial position. For another example, in order to install the upper core box 880 and the sandblasting plate 891, the core making machine control part 899 may: control the second lifting mechanism 816 to drive the upper core box fixing frame 815 to a suitable position; control the upper core box fixing mechanism 882 to move up The core box 880 is fixed on the upper core box fixing frame 815; the second lifting mechanism 816 is controlled to drive the upper core box fixing frame 815, the upper core box 880, and the sand-blasting plate 891 to a proper position; the sand-blasting plate fixing mechanism is controlled to shoot The sand board 891 is installed back on the sand storage mechanism 803; and the second lifting mechanism is controlled to descend to its initial position. If the sand storage mechanism 803 is not in the core making position when the sandblasting plate 891 is installed, the core making machine control unit 899 can control the sand storage mechanism moving mechanism of the core making machine 800 to move the sand storage mechanism 803 to the core making position. After the sandblasting board 891 and the upper core box 880 are installed, the core making machine 800 may continue to perform core making operations.

It should be noted that the above description of the process 1800 is for illustrative purposes only, and is not intended to limit the present invention. It can be understood that, after understanding the main concepts and principles of the present invention, a person of ordinary skill in the art may make non-creative modifications to the process 1800. These modifications may include combining and / or splitting certain steps, adding or deleting optional steps, changing the execution order of the steps, and so on. These changes fall within the scope of protection of this application.

In some embodiments, various mechanisms may be introduced on the core making machine 800 to further improve the cleaning and maintenance effect of the upper core box (or sandblasting board).

In some embodiments, the core making machine 800 may further include a cleaning mechanism (not shown, for example, brushes, scrapers, spray heads, negative pressure taps, robotic arms, robots, etc.) for aligning core making machine components (for example, (Upper core box, lower core box, sandblasting board, etc.) for cleaning. The cleaning mechanism can be located in the maintenance position. In the process 1100 (or process 1800), the core making machine control unit 899 may also send a cleaning signal to the cleaning mechanism, so that the cleaning mechanism cooperates with the lifting and rotating of the upper core box 880 to clean the upper core box 880 to improve the cleaning effect .

In some embodiments, an identification mechanism may be included on the upper core box 880, the lower core box 881, and / or the sandblasting plate 891. The core making machine 800 may further include a first sensor, which may be used to sense the identification mechanism on the upper core box 880, the lower core box 881, and / or the sandblasting plate 891 to generate corresponding first sensor data. For example, the identification mechanism may include a tag (for example, a radio frequency identification (RFID) tag), a magnetic strip, a number, a barcode, a two-dimensional code, etc., or a combination thereof, and the first sensor may include a radio frequency identification (RFID) sensor, a magnetic Sensors, infrared sensors, laser sensors, image sensors, etc. or combinations thereof. The first sensor may be located at any position of the core making machine 800, for example, on the core box moving cart 871, the upper core box fixing frame 815, the turning frame 130, the first fixing member 140, and the upper core box fixing mechanism 882 , Or other parts located in the core making position, maintenance position, or core taking position, etc.

The core making machine control part 899 may receive the first sensor data from the first sensor and generate at least a part of the third control signal or the fifth control signal based on the first sensor data. For example, the core making machine control unit 899 may obtain identification information of the upper core box 880, the lower core box 881, and / or the sandblasting board 891 based on the first sensor data (recorded in the identification chip, for example, model number, serial number, etc.) . Then, the core making machine control section 899 may determine the size information and / or structure information of the upper core box and / or the lower core box based on the obtained identification information (for example, through a lookup table), and based on the size information and / or structure information Determine the ascent height and / or flip angle when cleaning the upper core box (for example, through a look-up table or function). According to the determined ascent height and / or turning angle, the core making machine control unit 899 may generate at least a part of the third control signal or the fifth control signal. The above embodiment can make the upper core box 880 or the shooting plate 891 have a rising height and a rotation angle that can be set according to their size and / or structure when being cleaned, preventing the upper core box 880 or the shooting plate 891 from appearing during the cleaning process Collision with other components of the core making machine 800 (for example, the lower core box 881, the first conveying mechanism 874) improves the cleaning efficiency and reduces accidents.

Taking the cleaning of the upper core box 880 as an example, the core making machine control unit 899 can calculate the ascent height or the turning angle based on the first sensor data, and control the turning drive mechanism 169 to drive the turning frame 130 to drive the upper core box 880 along its horizontal rotation axis from its initial position. Rotate the turning angle at an angle (for example, 0 degrees), or control the lifting driving mechanism 150 to drive the lifting frame 120 to drive the turning frame 130 and the upper core box 880 from their initial height (for example, the first fixed position) to the raised height.

In some embodiments, the core making machine control unit 899 may also set or adjust the first fixing member 140, the second fixing member 710, and the upper core box fixing mechanism 882 based on the identification information, size information, and / or structural information. The method of fixing the core box 880 or the sandblasting plate 891 by the sandblasting plate fixing mechanism or the like makes the above mechanism more stable when fixing the core box 880 or the sandblasting plate 891 to prevent accidents. The core making machine control unit 899 can also set or adjust the lifting distance of the first lifting mechanism 816 or the second lifting mechanism 808 based on the above identification information, size information, and / or structure information, so that a variety of specifications of the upper core box 880 The sandblasting board 891 can be applied to the maintenance device 100 and the core making machine 800, expanding the application range of the maintenance device 100 and the core making machine 800.

The exhaust holes in the upper core box 880 or the lower core box 881 will cause defects in the sand core. Therefore, you can determine whether the exhaust holes in the upper core box 880 or the lower core box 881 can be determined by checking whether the sand core is defective. There is a blockage. In some embodiments, the core making machine 800 may also include a second sensor. The second sensor may be located in the core-taking position and used to obtain image data on the surface or inside of the sand core when performing the core-taking operation. For example, the second sensor may be an image sensor, an infrared sensor, a laser sensor, a radiation (eg, X-ray, etc.) imaging device, etc., or a combination thereof. The core making machine control unit 899 can also receive the above image data from the second sensor, and based on the image data, identify whether the manufactured sand core has defects (for example, through an image recognition algorithm and / or machine learning algorithm, etc.), According to the recognition result, the core making machine control unit 899 can recognize whether the exhaust holes in the upper core box 880 or the lower core box 881 are clogged. In response to the recognition result that the exhaust holes in the upper core box 880 or the lower core box 881 are clogged, the core making machine control section 899 may automatically initiate a maintenance operation (execution process 1100) or issue a warning message through the operation interface. With this embodiment, when the vent holes in the upper core box 880 or the lower core box 881 are blocked, the maintenance operation can be triggered in time and the user can be notified, thereby reducing the time delay and waste of raw materials caused by the blocking of the vent holes.

In some embodiments, the core making machine 800 may also include a third sensor. The third sensor may be located at the core making position and used to sense the pressure in the upper and lower core boxes during core making to generate corresponding second sensor data. For example, the third sensor may be an electronic barometer. The core making machine control unit 899 may also receive second sensor data from the third sensor, and identify whether the exhaust hole of the upper core box 880 or the lower core box 881 is blocked based on the second sensor data.

The core making machine 800 can recognize whether the exhaust holes of the upper core box 880 or the lower core box 881 are blocked based on only one of the second sensor data or the image data on the surface or inside of the sand core, or according to the second Sensing data and image data on the surface or inside of the sand core identify whether the exhaust holes of the upper core box 880 or the lower core box 881 are blocked to improve the accuracy of identification. The core making machine 800 may also perform this identification in other ways.
