[0025] Most punching and cutting die production lines still discharge waste from the discharge area manually. In actual work, when the discharge area is full of waste, it needs to be manually cleaned up. The machine needs to be shut down when cleaning the waste, which affects production efficiency. At the same time, it is easy for production accidents to occur due to workers' negligence.

[0026] To change this situation, refer to Figures 1 to 3 , the embodiment of the present application provides a discharge structure of a mold, specifically including an upper mold base 110, a lower mold base 120 and a driving assembly, wherein the upper mold base 110 is arranged directly above the lower mold base 120, and the upper mold base 110 can move toward the lower mold base 120 and close the mold with the lower mold base 120 under the drive of the machine tool. Specifically, a punching fixture is arranged on the upper mold base 110, and a punching positioning platform 130 is arranged on the lower mold base 120. After the workpiece is placed on the positioning platform 130, the punching fixture of the upper mold base 110 moves to the positioning platform 130 to perform a punching operation on the workpiece. The positioning platform 130 is provided with a punching opening corresponding to the position of the punching fixture, and a discharge guide groove 140 for collecting waste is arranged below the punching opening, and the position of the discharge guide groove 140 is positioned on the positioning platform 130. 0 and the lower die base 120. It should be noted that there are multiple discharge guide grooves 140, which are not limited here; further, the driving assembly includes a first driving member 210, a second driving member 230 and a reset member. The first driving member 210 is arranged on the upper die base 110, and the second driving member 230 is inserted into the lower die base 120 and connected to the end of the discharge guide groove 140. The lower die base 120 is provided with a limiting structure for limiting the movement direction of the second driving member 230. When the upper die base 110 moves to close the mold with the lower die base 120, the second driving member 230 is driven by the first driving member 210 to drive the discharge guide groove 140 to move linearly in the horizontal direction. When the upper die base 110 and the lower die base 120 are opened, the second driving member 230 is driven to return to its original position by the reset member.

[0027] Specifically, when in use, the upper die base 110 moves toward the lower die base 120 to realize the punching operation of the workpiece. During the mold closing process, the upper die base 110 drives the first driving member 210 to move to connect with the second driving member 230. Under the action of the first driving member 210, the second driving member 230 can perform a linear motion in the horizontal direction and stretch the reset component. Since the discharge guide groove 140 is connected to the second driving member 230, the discharge guide groove 140 follows the second driving member 230 to perform a linear motion. When the mold closing is completed, the first driving member 210 moves with the upper die base 110 and releases the connection with the second driving member 230. When the driving member 230 loses the external force, the rebound force generated by the reset component drives the second driving member 230 to return to its original position, and then the discharge guide groove 140 also returns to its original position, and through the closing and opening of the upper mold base 110 and the lower mold base 120, and the mutual cooperation of the various components of the driving assembly, the discharge guide groove 140 is driven to perform linear reciprocating motion, and the reciprocating motion drives the waste in the groove to move and vibrate, so that the waste can be discharged from the mold base in an orderly manner, and there is no need to stop the machine to clean the waste in the discharge guide groove 140, which greatly improves production efficiency. Furthermore, it saves the operating steps of the operator and ensures the personal safety of the operator.

[0028] In some embodiments, Figure 1 , Figure 2 and Figure 5 As shown, driving components are provided on both sides of the lower mold base 120, the two second driving components 230 are connected by a connecting rod 240, the discharge guide groove 140 is fixed to the connecting rod 240, and the two groups of driving components are driven to act simultaneously through the upper mold base 110, that is, the two first driving components 210 simultaneously drive the second driving components 230 to move in the same direction. Because the two second driving components 230 are connected by the connecting rod 240, and the discharge guide groove 140 is fixed to the connecting rod 240, the discharge guide groove 140 can be driven to perform linear reciprocating motion. The two groups of driving components make the force on the second driving component 230 more balanced and stable, and the movement of the discharge guide groove 140 is also more orderly.

[0029] In some embodiments, the driving component also includes a fixed seat 220, which is provided with a slide groove 222 arranged in a horizontal direction. The second driving member 230 is inserted into the slide groove 222, and the movement direction of the second driving member 230 is limited by the slide groove 222, wherein the gap between the second driving member 230 and the slide groove 222 is controlled at 0.5 mm, and the fixed seat 220 is provided with an entrance 221 connected to the slide groove 222 at a position corresponding to the first driving member 210. The first driving member 210 can enter the slide groove 222 from the entrance 221 to resist the second driving member 230. The force provided by the first driving member 210 can drive the second driving member 230 to move linearly in the horizontal direction. When the external force acting on the second driving member 230 by the first driving member 210 disappears, the automatic resetting of the second driving member 230 can be achieved by the resetting mechanism.

[0030] Specifically, the first driving member 210 drives the second driving member 230 to move through the inclined wedge structure. The setting of the inclined wedge structure enables the force of the first driving member 210 acting vertically on the second driving member 230 to be partially converted into a horizontal force that drives the second driving member 230 to move horizontally. Among them, the end of the first driving member 210 is provided with a first inclined surface 211, and the second driving member 230 is provided with a docking groove 231. The docking groove 231 is provided with a second inclined surface 232 parallel to the first inclined surface 211. The first inclined surface 211 and the second inclined surface 232 cooperate to form an inclined wedge structure, so that the vertical movement of the first driving member 210 can be converted into the horizontal movement of the second driving member 230. At the same time, the mold closing and opening of the upper mold base 110 and the lower mold base 120 are effectively utilized, and the discharge guide groove 140 is driven by the driving component to shake in the horizontal direction, thereby effectively shaking out the waste inside it from the mold base.

[0031] In some embodiments, Figure 4 As shown, the reset component includes an elastic member 270 and a first limiting member 250, the slide groove 222 runs through both sides of the fixed seat 220, the first limiting member 250 is fixed to the fixed seat 220 and blocks one end of the slide groove 222, one end of the elastic member 270 located in the slide groove 222 is connected to the first limiting member 250, and the other end is connected to the second driving member 230. When the upper mold base 110 moves to close the mold with the lower mold base 120, the first driving member 210 drives the second driving member 230 to move in a direction away from the first limiting member 250, thereby stretching the elastic member 270. When the effect of the first driving member 210 disappears, the elastic potential energy of the elastic member 270 acts on the second driving member 230, driving the second driving member 230 to return to its original position so that it can continue to perform linear reciprocating motion next time.

[0032] The elastic member 270 is preferably a compression spring.

[0033] The reset member further includes a height screw 260, which is inserted into the fixing seat 220, and one end of the height screw 260 enters the slide slot 222 to be fixedly connected to the second driving member 230. The height screw 260 limits the range of motion of the second driving member 230 to prevent the second driving member 230 from being separated from the slide slot 222 due to inertia, wherein the compression spring is sleeved on the height screw 260.

[0034] In some other embodiments, the discharge guide groove 140 is inclined, and the inclination angle of the discharge guide groove 140 is between 15° and 60°. The inclined discharge guide groove 140 is conducive to the discharge of waste. Furthermore, one end of the discharge guide groove 140 is fixedly connected to the second driving member 230, and a roller 280 is provided in the middle of the discharge guide groove 140 near the bottom of the other end. The provided roller 280 can reduce the sliding friction of the discharge guide groove 140.

[0035] In the mold using the above-mentioned waste discharge mechanism, during the mold closing process, the first driving member 210 is driven by the upper mold base 110 to move to connect with the second driving member 230. Under the action of the first driving member 210, the second driving member 230 can move linearly in the horizontal direction and stretch the elastic member 270. Since the discharge guide groove 140 is connected to the second driving member 230, the discharge guide groove 140 follows the second driving member 230 to move linearly. When the mold closing is completed, the first driving member 210 moves with the upper mold base 110 and releases the connection with the second driving member 230. The second driving member 230 loses external force and the elastic member 270 is stretched. The rebound force generated by the elastic member 270 drives the second driving member 230 to return to its original position, and then the discharge guide groove 140 also returns to its original position. Through the closing and opening of the upper mold base 110 and the lower mold base 120, and the cooperation of the various components of the driving assembly, the discharge guide groove 140 is driven to perform linear reciprocating motion, and the reciprocating motion drives the waste in the groove to move and vibrate, so that the waste can be discharged from the mold base in an orderly manner. There is no need to stop the machine to clean the waste in the discharge guide groove 140, which greatly improves production efficiency. Furthermore, it saves the operating steps of the operator and ensures the personal safety of the operator.

[0036] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
