All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

In the inductive hot pressing process, the common equipments are an implanter, a powder filling machine and a hot press. The implanting machine is used for placing the wound inductor into an inductor station hole of the die, the powder filling machine is used for filling powder into the inductor in the die, and the hot press machine is used for carrying out electric hot press forming on the filled inductor. Thus, the mold needs to be moved between different devices. At present, the conveying belts are independently arranged among different devices, so that the production line devices are more complicated and difficult to control, and the input cost of the production line is increased.

The invention provides a mould carrying track, which is characterized in that parallel guide rails are connected with each other to form a closed path, and a steerable guide rail is arranged at the joint of the parallel guide rails, so that a mould can circularly move on the track to be conveyed to different equipment stations.

Example (b):

as shown in fig. 1, the mold carrying track of the present embodiment is used for circularly conveying the induction hot-pressing mold, so that the induction hot-pressing mold can be circularly moved to the implanter, the powder filling machine and the hot press along the track. The mold 100 is fastened on the parallel guide rails 200 of the track and can circularly move back and forth on the track, so that the automatic assembly line operation of the electric induction hot-press molding is realized, and the production efficiency is improved. The mould carrying track sequentially passes through the stations of the implanter, the powder filling machine and the hot press and is mutually connected to form a rectangular closed track transmission path. Specifically, referring to fig. 1 to 3, each side of the formed rectangular mold carrying rail includes five pairs of parallel guide rails 200, each pair of parallel guide rails 200 is arranged at the same interval, and the horizontal and vertical parallel guide rails 200 are connected to each other to form a closed path. At the intersection of the horizontal rails and the vertical rails, in order to allow the mold to be smoothly switched to a different parallel rail 200 at the intersection, a steerable rail 230 is provided at the intersection between the parallel rails 200. Taking the vertical guide rail as an example, each vertical guide rail is connected with four horizontal guide rails, so that a steerable guide rail 230 is arranged at each of the four joints, and the four steerable guide rails 230 divide the vertical guide rail into five sections. The communication between each pair of parallel rails 200 in the horizontal path or between each pair of parallel rails 200 in the vertical path can be achieved by the driving device driving the steerable guide rails 230 to change the orientation. When the mold 100 moves to the steerable guide 230, the mold 100 needs to stop there to wait for the orientation of the steerable guide 230 to be switched, and then the mold can move along the new guide. Accordingly, a stop mechanism is provided adjacent to the steerable rail 230 to effect stopping of the mold 100 on the steerable rail 230. After the moving direction of the mold 100 is switched, the mold 100 is driven to move continuously along the current parallel guide rail 200 by the transmission device arranged adjacent to the parallel guide rail 200.

In this embodiment, the driving device is specifically a rotary cylinder 250, and the bottom end of the steerable guide rail 230 is connected to the rotary cylinder 250. The rotating cylinder 250 may rotate the steerable guide rail 230 by 90 degrees each time, so that the steerable guide rail 230 communicates with the horizontal path or communicates with the vertical path.

In some embodiments, the drive means is embodied as a toggle spring, ratchet, or the like.

Specifically, the stop mechanism of the present embodiment includes a positioning pin 240 and an air cylinder, and the air cylinder is connected to a bottom end of the positioning pin 240. When the mold 100 moves to the set stop position, the air cylinder operates, and the positioning pin 240 is ejected, so that the positioning pin 240 can be snapped into the corresponding hole on the mold 100, and the mold 100 is prevented from moving continuously. Accordingly, when the cylinder is restarted, the pin 240 is retracted and the mold 100 may continue to move.

Further, two positioning pins 240 of the present embodiment are oppositely disposed on the outer side of the parallel guide rail 200 connected to the steerable guide rail 230. The mold 100 is more stable and the mold 100 will not shift due to indirect forces from the turning of the steerable rail 230.

It should be noted that other stop components in the art, such as a limit stop, a magnetic attraction device, etc., may be used as the stop mechanism.

Further, positioning devices, such as the positioning pins 240 of the embodiment, are further disposed at corresponding positions of each path of the operation track, so that the mold 100 can stay on the parallel guide rails 200 at the positioning devices to achieve the desired positioning of the mold 100. The specific position of the positioning means needs to be determined depending on the duration of each process on the packaging line and the moving speed of the mold 100.

The transmission device is a belt transmission mechanism arranged between two guide rails of the parallel guide rail 200, and comprises a synchronous belt 260, a servo motor for driving the synchronous belt, and a sliding plate 270 connected with the synchronous belt 260, and a traction mechanism for coupling with the die 100 is arranged on the sliding plate 270. The synchronous belt 260 is driven by the servo motor to drive the sliding plate 270 to move, and the sliding plate 270 moves to pull the mold 100 to move on the guide rail through the traction mechanism. The drawing mechanism comprises a drawing pin 220 arranged at the top end of the sliding plate 270 and an air cylinder arranged at the bottom end of the sliding plate 270, wherein the air cylinder is connected with the bottom end of the drawing pin 220 and is used for driving the drawing pin 220 to pop up or retract so as to realize the coupling with the die 100.

Specifically, in the present embodiment, the fixing block 280 is installed on the sliding plate 270, and the towing pin 220 is disposed on the fixing block 280, so that the specific position of the towing pin 220 can be easily changed by changing the position of the fixing block 280. Further, two fixing blocks 280 are installed on the sliding plate 270, and accordingly, a total of two drawing pins 220 are provided at intervals along the extending direction of the parallel guide rail 200, and the die 100 can obtain strokes of different distances by selectively coupling with different drawing pins 220.

Further, a support slide rail 290 is disposed between the two parallel guide rails 200, and the support slide rail 290 is coupled to the bottom end of the slide plate 270, so that the slide plate 270 moves more stably.

When the inductor is used, the wound inductor is placed in a mold cavity of the mold 100 on an implanter, the mold 100 moves along a rail to a powder filling machine to quantitatively add hot pressing powder, then moves to a hot press along the rail, the inductor is subjected to hot pressing molding through the hot press, the inductor on the mold 100 is demolded and taken out, then moves to the implanter along the rail, and the process is repeated. The packaging line equipment is simple, and higher production efficiency is obtained.

In summary, the present invention provides a mold transporting device, which comprises a mold transporting device, a stopping mechanism, a driving device, a mold transporting device, and a mold transporting system.

Because the mould that uses in the inductance pressing technology of current needs to carry between different stations, does not possess the ability of moving on the delivery track.

Therefore, the invention also provides a die for inductance processing, which is arranged on the die carrying track, wherein the die can be coupled on parallel guide rails in different directions by arranging the turnable sliding block, and the die is indirectly driven to move on a packaging line by driving the traction part through the transmission device.

The embodiment is as follows:

referring to fig. 4 to 6, the mold 100 of the present embodiment is a cubic frame structure, and mainly includes a female mold half 120, a base 110, and a lower punch holder 130, which are detachably connected, wherein the female mold half 120 is provided with a mold cavity 121 for embedding an inductor coil and holding powder. Specifically, the female mold 120 of the present embodiment has 1024 mold cavities, which can significantly improve the production efficiency compared to the conventional 64 mold cavities. A lower punch 140 corresponding to the cavity 121 of the mother die 120 is fixed to the lower punch holder 130. Compared with the conventional upper die, middle die and lower die structure, the die has simpler structure; when the mould is used for hot pressing, only one heating flat plate is arranged on the hot pressing equipment to replace an upper mould, and the mould closing and hot pressing operation can be completed without arranging a punching needle on the hot pressing equipment, so that the cost is reduced, and the reliability is improved. It is also convenient to disassemble the lower punch holder 130 to replace the lower punch 140. During hot pressing, a driving device on the hot pressing equipment is connected to the lower punching needle fixing frame 130 to drive the lower punching needle 140 to extend into the die cavity 121, so that powder in the die cavity 121 is punched.

In some embodiments, the lower punch holder 130 may not be provided in the die 100, so that the die 100 can be used in an existing hot pressing apparatus having an upper punch.

Referring to fig. 5, in order to realize that the mold 100 can move on the guide rails, at least one pair of steerable slide blocks 111 is provided at the bottom end of the base 110, and each pair of steerable slide blocks 111 is adapted to be coupled to a pair of parallel guide rails 200 as shown in fig. 4. The steerable sliding block 111 is movably connected to the bottom end of the base 110, and the orientation of the steerable sliding block 111 can be correspondingly adjusted according to the orientation of the guide rail, so that the steerable sliding block 111 has the capability of moving on the guide rail in different orientations. It should be noted that the specific structure of the steerable slide block 111 is not limited, and is related to the specific shape of the coupled parallel guide rails 200; and a specific disposition position may be selected according to the structure and size of the base 110.

The specific connection manner of the steerable sliding block 111 and the base 110 is not limited, for example, in this embodiment, the rotatable shaft 112 is connected to the bottom end of the base 110 in a snap-fit manner, and the steerable sliding block 111 is fixed on the rotatable shaft 112, but of course, the steerable sliding block 111 may also be connected to the bottom end of the base 110 in other rotation connection manners commonly used in the art.

The mold 100 in this embodiment is specifically installed on a track as shown in fig. 1, the track is provided with a steerable guide rail 230, and an air cylinder connected to the steerable guide rail 230 is further provided, the air cylinder drives the steerable guide rail 230 to rotate by 90 degrees, so that the guide rails in different directions can be communicated, the steerable guide rail 230 rotates and simultaneously drives the steerable slide block 111 to rotate by the same angle, and the mold 100 circularly moves on a horizontal track and a vertical track.

For a large-sized mold, preferably, as in this embodiment, one steerable slide block 111 is disposed at each of four corners of the base 110, so as to form two pairs of steerable slide blocks 111. Making the mold 100 more stable when moving.

A drawing part is further disposed at the bottom end of the base 110, and the drawing part can be used for coupling with a transmission device on the carrying rail, so that the transmission device drives the mold 100 to move on the guide rail through the drawing part when working. Those skilled in the art will readily appreciate that the specific shape and configuration of the traction portion will vary from one transmission configuration to another. Specifically, in this embodiment, a plurality of drawing holes 113 are formed in the lower surface of the base 110, and one or more of the drawing holes 113 are correspondingly connected to the drawing pins 220 on the rail, that is, the drawing pins 220 on the rail only need to be inserted into the drawing holes 113 to drive the mold 100 to move on the rail.

Further, in order to be more suitable for the working environment of the packaging line, it is preferable that the drawing holes 113 are provided in pairs, respectively symmetrically provided at both sides of the axis of symmetry of the lower surface of the base 110, so that it is not necessary to carefully check the up and down positions of the drawing pins 220 based on the change of the orientation of the mold 100 when the mold 100 moves on the upper or lower rail of the horizontal path, for example. Specifically, the present embodiment is provided with eight drawing holes 113 along the periphery of the base 110, and the drawing holes are symmetrically disposed on two sides of two symmetrical axes (a transverse center line and a longitudinal center line) on the lower surface of the base 110, and the drawing pin 220 coupled with the drawing holes 113 can have eight positions, so that the use is more convenient.

Further, in this embodiment, a plurality of limiting holes 114 are further formed in the circumferential direction of the lower surface of the base 110, and are used for matching with the positioning pins 240 on the track, when the mold 100 needs to be switched to the tracks in different directions, the mold 100 accurately stays at a designated position, after the steerable slide block 111 is driven by the steerable guide rail 230 to rotate by 90 degrees, that is, after the steerable slide block 111 is engaged with the guide rail in the target direction, the positioning pins 240 are disengaged from the limiting holes 114, so that the mold 100 continues to move on the track in the target direction.

As shown in FIG. 1, in this embodiment, as many as 3 sets of molds 100 are arranged on the mold carrying track, so as to ensure synchronous operation of the hydraulic press, the implanter and the powder filling machine.
