[0028] The present utility model provides a waste discharging device for side punching of a mold as shown in Figure 1 which includes a lower template 1 and further includes:

[0029] A punching mechanism 2, arranged on the top of the lower template 1, for performing side punching operations on regular cylindrical workpieces;

[0030] A discharging mechanism 3, arranged inside the punching mechanism 2, for discharging the waste generated by punching.

[0031] In order to conveniently perform side punching on cylindrical workpieces, as shown in Figures 1-3 the punching mechanism 2 includes a support base 201. The support base 201 is arranged on the top of the lower template 1. A connecting bolt 202 is arranged between the outer side of the bottom of the support base 201 and the lower template 1 and is fixedly connected through the connecting bolt 202. Punching holes 203 are formed in the inner walls at both ends of the support base 201. The support base 201 can be installed and fixed through the connecting bolt 202, enabling the staff to conveniently install and replace the punching mechanism 2 according to production requirements. The setting of the punching holes 203 enables the device to conveniently perform side punching operations on cylindrical workpieces

[0032] In order to conveniently discharge the waste generated during the punching process, as shown in Figures 1-2 and Figure 4As shown in the figure, the discharging mechanism 3 includes a push plate 301, which is arranged inside the support seat 201. At both ends of the bottom of the push plate 301, movable baffles 303 are rotatably installed. At the bottom of both movable baffles 303, traction plates 305 are arranged. At the bottom of both traction plates 305, a movable seat 306 is rotatably installed. At the bottom of the movable seat 306, a hydraulic cylinder 307 is arranged. When the hydraulic cylinder 307 works, it can drive the movable seat 306 to move. Then, under the traction of the traction plate 305, the opening and closing state of the movable baffle 303 can be adjusted. Thus, the push plate 301 can conveniently push the waste generated during the stamping process downward or discharge it upward through the position of the cover plate 204, making the discharge of the waste more convenient.

[0033] In order to keep the push plate 301 stable during the movement, as Figures 2-4 shown in the figure, cover plates 204 are rotatably installed at both ends of the top of the support seat 201. Activity grooves 205 are formed on both sides of the inner wall of the support seat 201. Slide blocks 302 are fixedly installed on the outer walls of both sides of the push plate 301. The outer walls of the two slide blocks 302 are respectively movably connected with the inner walls of the two activity grooves 205. The activity grooves 205 can limit the movement of the slide blocks 302, so that the push plate 301 remains stable during the movement and can stably discharge the waste.

[0034] In order to enable the push plate 301 to stably discharge the waste, as Figures 2-4 shown in the figure, through holes for discharging the side punching waste are formed on the inner walls of both ends of the push plate 301. The area size of the top view horizontal cross-section of the through hole is larger than the area size of the left view vertical cross-section of the stamping hole 203. The area size of the top view horizontal cross-section of the movable baffle 303 is the same as the area size of the top view horizontal cross-sections of the through holes at both ends of the push plate 301. The diameter size of the push plate 301 is the same as the inner diameter size of the support seat 201. The movable baffle 303 can close or open the through holes at both ends of the push plate 301, so that the waste can conveniently pass through the through holes.

[0035] In order to conveniently adjust the opening and closing of the movable baffle 303, as Figure 2 and Figure 4 shown in the figure, fixed seats 304 are fixedly installed at the bottom of both movable baffles 303. The inner sides of the two fixed seats 304 are respectively rotatably connected with the tops of the two traction plates 305. The bottom of the inner wall of the lower template 1 is fixedly connected with the hydraulic cylinder 307. The output end of the hydraulic cylinder 307 is fixedly connected with the bottom of the movable seat 306. The lower template 1 can install and fix the hydraulic cylinder 307. When the hydraulic cylinder 307 works, the movable seat 306 moves. Then, under the connection between the traction plate 305 and the fixed seat 304, the movable baffle 303 can be driven to rotate.

[0036] When performing a punching operation on the side of a cylindrical workpiece, the punching mechanism 2 is installed on the top of the lower template 1 according to requirements. The support base 201 can be installed and fixed using the connecting bolts 202. Then, the cylindrical workpiece is sleeved outside the support base 201. The die can perform a side punching operation on the positions of both sides of the workpiece outside the punching holes 203. The waste generated during the punching process naturally falls from the inside of the support base 201. As the punching work progresses, the hydraulic cylinder 307 contracts, driving the movable seat 306 to move downward. Then, under the traction of the traction plate 305, the two movable baffles 303 rotate downward. When they rotate to the maximum angle, the hydraulic cylinder 307 continues to contract, driving the push plate 301 to move downward along the inner wall of the support base 201, which can push the waste downward. At this time, when performing a side punching on the cylindrical workpiece, the generated waste can fall downward through the through holes at both ends of the push plate 301. At the same time, when the punching is completed, the hydraulic cylinder 307 extends to reset the movable baffle 303, and continues to extend to push the push plate 301 upward, which can push the waste falling on the top of the push plate 301 upward. Then, by opening the two cover plates 204, the push plate 301 can discharge the waste on the top from the top of the support base 201, making the discharge of the waste more convenient and thorough, avoiding the accumulation and blockage of waste inside the support base 201, ensuring the stable progress of the subsequent side punching operation. At the same time, the movable groove 205 can limit the movement of the slider 302, making the push plate 301 stable during the movement, so that the push plate 301 can stably discharge the waste from the inside of the support base 201. This embodiment specifically solves the problem in the prior art that waste is likely to accumulate and block inside the support component of the cylindrical workpiece, which will affect the subsequent side punching work.

[0037] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
