In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 and 2, a casting system 100 according to an embodiment of the present invention includes a bin 110, a forming stopper 130 disposed around an edge of a casting body to be formed, a guide tube 150, and a driving device 170 for driving the forming stopper 130 to reciprocate along a first direction a.

Specifically, a feed opening 111 is provided at a lower side of the bin 110.

The contoured stop 130 is reciprocally movable in a first direction a. It can be understood that the molded stopper 130 has a function of molding the casting body, so that the molded stopper 130 does not get away from the casting body or the space of the casting body to be molded when the molded stopper 130 moves back and forth along the first direction a during the casting process.

In this embodiment, the first direction a is a vertical direction. It is understood that in other embodiments, the first direction a is not limited to a vertical direction, but may be a horizontal direction or a direction inclined to the horizontal direction according to specific requirements.

One end of the material guiding pipe 150 is connected to the material outlet 111, and the pipe wall of the other end is fixedly connected to the forming stopper 130. Specifically, the guide tube 150 serves to guide the casting material flowing out of the lower opening 111 of the hopper 110 to the inside of the forming stopper 130.

It is understood that the inside of the molded stopper 130 refers to the side of the molded stopper 130 that is adjacent to the molded body or the side of the molded stopper 130 that is adjacent to the space with the molded body when the gating system 100 is performing a gating operation.

A molding stop 130 is disposed around the edge of the casting to be molded to shape the casting to prevent overflow of the casting material. In addition, the molding stopper 130 can reciprocate along the first direction a to improve the quality of the outer surface of the cast body, i.e., the cast body with high quality of the outer surface can be formed without secondary processing, the operation efficiency is high, and the construction period is further reduced.

Specifically, in the present embodiment, the outer surface of the casting body to be cast is a plane, and the surface of the inner side of the corresponding molding stopper 130 is also a plane. When the cast body is cast, the molding stopper 130 moves back and forth along the first direction a, so that the flatness of the outer surface of the cast body is improved, that is, the quality of the outer surface of the cast body is improved, the secondary leveling procedure is avoided, and the efficiency is improved.

In addition, the material guiding pipe 150 can guide the casting material to the inner side of the forming stopper 130, and the casting material is prevented from flowing to the outer side of the forming stopper 130 by the blocking of the forming stopper 130, so that the waste of the casting material is avoided, and the cost is reduced.

It should be noted that when the material guiding pipe 150 guides the casting material flowing out from the material outlet 111 of the storage bin 110 to the inner side of the formed stopper 130, the casting material can be deposited on the inner side of the formed stopper 130 by spraying or pressing.

In this embodiment, the gating system 100 includes a driving device 170 that can drive the formed stopper 130 to reciprocate along the first direction a. If the position or size of the forming stopper 130 is inconvenient to operate, the difficulty of the operation of the forming stopper 130 is reduced by the driving device 170.

Specifically, in the present embodiment, the driving device 170 includes a guide rail 171 and a pulling mechanism 173 for driving the guide rail 171 to reciprocate along the first direction a, and the forming stopper 130 is fixedly disposed at the distal end of the guide rail 171.

In this embodiment, traction mechanism 173 includes hydraulic ram 1733, and hydraulic ram 1733 is coupled to rail 171 by way of a traction cable 1731. The hydraulic cylinder 1733 drives the pulling rope to extend or contract along the first direction a, so as to drive the guide rail 171 to reciprocate along the first direction a, and further drive the forming stopper 130 to reciprocate along the first direction a.

More specifically, a robot joint 1711 is fixedly disposed on the guide rail 171, and the traction mechanism 173 is connected to the robot joint 1711 through a traction rope 1731 to drive the guide rail 171 to reciprocate along the first direction a.

It is understood that in other embodiments, the robotic joint 1711 may be replaced with other structures that may be secured to the pull-cord 1731 or around which the pull-cord 1731 may be passed.

Of course, in another embodiment, the device for driving the pull rope 1731 to extend or contract in the first direction a is not limited to the hydraulic cylinder 1733, but may be a telescopic cylinder or the like.

In one possible embodiment, the driving device 170 can also drive the forming stopper 130 to move along the first direction a to another casting position of the casting body.

Of course, it is understood that in further embodiments, the structure of the driving device 170 is not limited thereto. Optionally, in another embodiment, the driving device may be a mechanical arm with another structure, the molding stopper is fixedly disposed at a distal end of the mechanical arm, and the molding stopper is driven to move by the movement of the mechanical arm.

In this embodiment, the driving device 170 further includes a suspension arm 175 movable in the second direction b, and the traction mechanism 173 is disposed on the suspension arm 175. That is, the cantilever 175 moves along the second direction b to drive the molding stopper to move along the second direction b, so as to complete the molding of the casting body at other positions. Specifically, the cantilever 175 may be driven to move in the second direction b by a lift truck or the like.

It should be noted that in other embodiments, depending on the particular configuration of the tape-molded casting, cantilever arms 175 may also be configured to rotate to complete the molding of the casting at other locations.

In this embodiment, the second direction b is perpendicular to the first direction a. It is understood that the second direction b may not be perpendicular to the first direction a, and even the second direction b may be co-directional with the first direction a, according to specific work requirements.

In this embodiment, the gating system 100 further includes a control device for controlling the operation of the gating system 100. Specifically, the control device may be used to control the operation, i.e. detection, of each component in the system, such as controlling and detecting the operation of the driving device 170, controlling the discharging speed of the discharging opening 111 of the storage bin 110, and the like, and of course, may also detect the composition of the casting material, and the like.

The control device controls the pouring system 100 to complete pouring operation, so that the number of operators for pouring operation is reduced, namely, manpower is reduced. In addition, the problem of poor pouring quality caused by human factors can be reduced.

In addition, the control device controls the gating system 100 to complete the gating operation, and an operator can be located at a position far away from the gating site, so that safety accidents are avoided.

Moreover, the control device controls the pouring system 100 to complete pouring operation, so that continuous operation can be realized, and the operation efficiency is improved.

Of course, in an operation environment with a low safety factor, the operation may be performed directly by a human operator without providing a control device.

The control device includes a programmable logic controller. I.e. to preset the possible motion trajectory of the shaped stop in a programmed manner. And during specific operation, the operation information is transmitted through the programmable logic controller. Of course, in other embodiments, other types of controllers may be employed.

Optionally, in this embodiment, the control device further includes a motion control sensor 191 for detecting the driving device 170. Through the motion control sensor 191, the information of the motion tracks of the parts of the driving device 170 and the forming stopper 130 can be collected, the collected information is analyzed and then transmitted to the programmable logic controller, the operation information is transmitted through the programmable logic controller, the motion tracks of the parts of the driving device 170 and the forming stopper 130 are tracked and collected again, and so on, so that the motion track of the forming stopper 130 can be accurately controlled.

In this embodiment, the control device further comprises a three-dimensional scanning mechanism 193 for detecting the position of the space to be cast inside the molding stopper 130 and the quality of the cast body.

The position of the space to be poured inside the forming stopper 130 is scanned by the three-dimensional scanning mechanism 193 to determine the proper position of the forming stopper 130, and the motion of the driving device 170 can be analyzed and planned accordingly to drive the forming stopper 130 to move according to the proper trajectory.

The mass of the cast body is scanned by a three-dimensional scanning mechanism 193. The control device can analyze whether the quality of the casting body meets a preset requirement or not according to the scanning information of the three-dimensional scanning mechanism 193. If the quality of the casting body is detected not to meet the preset requirement, the operation speed of the molding stopper 130 or the discharging speed of the casting material can be adjusted in time by changing the operation speed or the discharging speed of the casting material, so that the quality of the casting body can meet the requirement, and the rework phenomenon can be avoided.

In this embodiment, the motion control sensor 191 and the three-dimensional scanning mechanism 193 are both disposed on the bin 110. It will be appreciated that in alternative embodiments, the motion control sensor and the three-dimensional scanning mechanism may be located elsewhere depending on the particular configuration of the runner system.

In this embodiment, the molded stopper 130 is in a flat plate shape, and the surface of the molded stopper 130 close to the casting space is a plane, so that some casting objects with a plane outer surface, such as walls, floors, gutters, stairs, roofs, etc., can be cast. It is understood that when some casting bodies with plane outer surfaces are cast, the molded stopper is not limited to be flat, and the surface of the molded stopper close to the casting space is flat, or the corresponding portion of the surface of the molded stopper close to the casting space in the casting space is flat.

Of course, in other embodiments, the molded stopper is not limited to being plate-shaped, but the shape of the molded stopper may be specifically set according to the specific shape of the cast body. If the casting body to be cast is cylindrical, the shape of the molded stopper may be cylindrical, or any shape having a circular through hole matching the shape of the casting body may be provided; if the casting body to be cast is duckbilled, the shaped stopper may be formed so as to be duckbilled, or any other structure having a duckbilled surface.

In this embodiment, the gating system 100 includes two molded stoppers 130, and correspondingly two feed openings 111 are provided on the lower side of the storage bin 110.

When both sides of the casting body of the wall isoplanar are required to be cast, two molding stoppers 130 can be used to cast simultaneously on both sides to improve the rate of adjustment. Alternatively, the casting may be cast on only one side, and then two castings may be cast simultaneously by adjusting the positions of the two molded stoppers 130 to improve efficiency.

In other embodiments, the same manner as above can be used to increase efficiency if the shaped barrier is duckbilled.

In another embodiment, when the casting body is cylindrical and the corresponding molding stopper is cylindrical, if the height of the molding stopper along the axial direction of the casting body is less than the height of the casting body, the casting body with different height sections can be simultaneously cast by the two molding stoppers, so as to improve the efficiency.

Of course, in further embodiments, the gating system is not limited to including two molded flights, but may include one or more than two molded flights. When the gating system includes more than two profiled stoppers, the gating efficiency can be increased even more.

Alternatively, in this embodiment, the molded flight 130 can be rotated to accommodate casting in different positions. For example, when two surfaces of one step of the staircase need to be poured, the two molded stoppers 130 can be rotated to make the inner sides of the two molded stoppers 130 perpendicular and match with two sides of the pouring space to be poured, so that the pouring of the step can be completed at one time, and the efficiency is improved.

Of course, in a possible embodiment, the inner surface of the profiled stop can also be provided as a surface with folds, so that the step can be cast in one profiled stop.

In this embodiment, the bin 110 is also fixed to the cantilever 175. Of course, in other embodiments, the bin 110 may be disposed on other structures at locations that meet the feeding requirements.

Optionally, a flow monitor is disposed at an outlet of the storage bin 110 to monitor the amount of the casting material during the casting process, so that the casting material can be supplemented in time, and the casting process can be prevented from being interrupted due to insufficient casting material.

In this embodiment, the material guiding tube 150 is a metal hose, and the metal hose can maintain the connection between the two ends of the material guiding tube and the material feeding opening 111 and the forming stopper 130 by changing the shape of the metal hose when the forming stopper 130 reciprocates. In other embodiments, the material guiding tube is not limited to a metal tube, but may be other tubes capable of carrying casting materials, or may be a telescopic tube, or may be an elastic tube, etc.

In this embodiment, the gating system 100 further includes a servo motor for coordinating the actions of the driving device 170.

In addition, the gating system 100 also includes a battery to power the operation of the gating system. In other embodiments, the power supply of the gating system is not limited to a battery, and an alternating current power supply and the like can be adopted according to the specific use environment.
