[0019] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the present invention are further described below in conjunction with the accompanying drawings and through specific implementation methods. It is understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for the convenience of description, only the parts related to the present invention are shown in the accompanying drawings, rather than all of them.
[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0021] The utility model relates to a waste releaser, which specifically includes a mounting seat 1 and a cover plate 2 connected thereto, wherein the mounting seat 1 is provided with a spring 3 and a guide pin press rod 4, and a screw 5 for fixing the mounting seat 1 and the cover plate 2. The workpiece is positioned by the lower die positioning pin in a natural state, and the waste releaser moves downward with the upper die, and the guide pin press rod guides and starts to press the workpiece after contacting the positioning pin, and the trimming knife moves downward to contact the workpiece and starts to shear the workpiece to generate waste, and after the waste is cut off, the upper die of the mold opens and separates, and the waste releaser continues to buckle the waste to prevent the waste from sticking to the trimming knife moving upward. When the trimming knife is completely separated from the waste, the waste releaser is separated from the waste, and the waste falls into the waste chute, completing the trimming action.
[0022] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.
[0023] like Figure 1 As shown, the utility model provides a waste releaser, including a mounting seat 1, a cover plate 2, a spring 3, and a guide pin press rod 4. The mounting seat 1 is provided with a mounting hole 11, and the spring 3 and the guide pin press rod 4 are sequentially arranged in the mounting hole 11 from top to bottom along the mold pressing direction. The end of the guide pin press rod 4 extends downward from the mounting hole 11, and the end of the guide pin press rod 4 is provided with a positioning pin hole 43 that cooperates with the workpiece positioning pin.
[0024] The mounting seat 1 is connected to the upper die, and a mounting hole 11 having matching tolerance requirements with the guide pin press rod 2 is processed in the mounting seat 1, and a spring 3 matching with it is installed in the mounting hole 11, which can play a role in pressing the material. The end of the guide pin press rod 4 is also processed with a positioning pin hole 43 matching with the positioning pin, which can play a role in pressing the material while positioning.
[0025] The cover plate 2 is arranged above the mounting hole 11 and connected to the mounting seat 1 body via screws 5 .
[0026] The guide pin press rod 4 includes a mounting portion 41 and a press portion 42. The mounting portion 41 is arranged in the mounting hole 11, and the press portion 42 extends downward from the mounting hole 11. The positioning pin hole 43 is arranged at the end of the press portion 42 along the rod body direction. The guide pin press rod 4 is a stepped cylinder, and the outer diameter of the mounting portion 41 is larger than the outer diameter of the press portion 42. The profile of the press portion 42 matches the profile of the workpiece. The material of the guide pin press rod 4 is a high-strength copper alloy.
[0027] The guide pin press rod 4 is relatively small in size and can replace the press core to press the material in the narrow position or insufficient space of the workpiece. The guide pin press rod 4 can avoid the trimming knife and effectively use the positioning pin to position the workpiece. The guide pin press rod 4 is contoured and more closely fits the workpiece surface. The guide pin press rod 4 is made of high-strength copper alloy with good processability and good use effect. After contouring, it can fit the cover surface well, has high pressure resistance and wear resistance, and can greatly improve the service life of the waste releaser.
[0028] Working process:
[0029] The workpiece is positioned by the lower die locating pin in a natural state, and the waste releaser moves toward the lower die together with the upper die. After the guide pin pressing rod 4 of the waste releaser contacts the locating pin, the locating pin hole 43 cooperates with the locating pin to lock the waste releaser, and the waste releaser guides and starts to press the workpiece; the trimming knife moves downward to contact the workpiece and starts to shear the workpiece, and the remaining part becomes waste. After the waste is cut off, the upper die of the mold opens and separates from the lower die, and the waste releaser continues to buckle the waste to prevent the waste from sticking to it and moving upward with the trimming knife; after the trimming knife is completely separated from the waste, the waste releaser is separated from the waste, and the waste falls into the waste chute, completing the trimming action.
[0030] The advantages of the utility model are:
[0031] The structure of the scrap releaser is relatively simple, and it is used for trimming and pressing materials at the precision positioning holes of the outer plate mold to better complete the removal of scrap. The workpiece process holes are fully utilized, the workpiece is positioned by the positioning pin, and the guide pin pressing rod of the scrap releaser is guided to press the workpiece. The mounting seat of the scrap releaser has a spring inside, and the end of the guide pin pressing rod is also processed with a positioning pin hole that cooperates with the positioning pin, which can also play a role in pressing the material while positioning.
[0032] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
