Inside the movable template, there is a detachable convex template corresponding to the detachable concave template. On one side of the movable template, there are several telescopic devices for driving the movement of the movable template. The output shaft of the telescopic device passes through the fixed plate of the die holder and the side wall of the movable template. The output shaft of the telescopic device is connected to the movable template by a thread. The movable template is a concave plate. On both open sides of the movable template, there are several pressure monitoring devices. The detachable convex template is located inside the groove of the movable template. On the bottom surface of the detachable convex template, there is a stamping telescopic device. The output shaft of the stamping telescopic device passes through the movable template, the bottom surface of the detachable convex template, and the fixed plate of the die holder. The output shaft of the stamping telescopic device is connected to the detachable convex template by a thread. On one side of the fixed plate of the die holder, there is a control panel for controlling the telescopic device and the stamping telescopic device. The stamping telescopic device, the telescopic device, and the pressure monitoring device are all connected to the control panel by data lines.

[0007] As an improvement, the pressure monitoring device is connected to the side wall of the movable template by welding.

[0008] As an improvement, below the concave template, there is a storage groove for receiving stamping scraps, and the storage groove passes through the inside of the fixed template.

[0009] As an improvement, below the storage groove, there is a scrap recycling box.

[0010] As an improvement, the concave template is connected to the fixed template by a bolt structure.

[0011] As an improvement, the bases of the stamping telescopic device and the telescopic device are both connected to the fixed plate of the die holder by a bolt structure.

[0012] The advantages of the present utility model compared with the prior art are as follows: By the extension of the telescopic device, the protruding edges on both sides of the movable template fix the edges of the raw material. After receiving a certain extrusion force, the pressure monitoring device alarms, causing the telescopic device to stop extending. However, the detachable convex template located inside the movable template continues to press down under the action of the stamping telescopic device to perform stamping operations on the raw material. Because the protruding edges on both sides of the movable template press the edges of the raw material before stamping, when the detachable convex template stamps, the raw material will not deform inward, ensuring the quality of the finished product.

[0018] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0019] As shown in the attached drawings of the specification Figure 1 、 2 、3, it includes a die holder 1. Inside the die holder 1, there are a fixed template 11 and a movable template 12. Inside the fixed template 11, there is a removable concave template 13. Inside the movable template 12, there is a removable convex template 14 corresponding to the removable concave template 13. On one side of the movable template 12, there are several telescopic devices 2 for driving the movement of the movable template 12. The output shaft of the telescopic device 2 passes through the fixed plate of the die holder 1 and the side wall of the movable template 12. The output shaft of the telescopic device 2 is connected to the movable template 12 through threads, and the base of the telescopic device 2 is connected to the fixed plate of the die holder 1 through a bolt structure. The concave template 13 is connected to the fixed template 11 through a bolt structure. By starting the telescopic device 2, the fixed template 11 and the removable convex template 14 move towards the removable concave template 13, so that the raw material above the removable concave template 13 is extruded out of the raw material by the removable convex template 14 under the action of the removable convex template 14, thus completing the stamping operation.

[0020] Below the concave template 13, there is a storage groove 15 for receiving stamping scraps. The storage groove 15 passes through the inside of the fixed template 11. Below the storage groove 15, there is a scrap recycling box 6. The scraps generated by stamping fall into the scrap recycling box 6 below the storage groove 15 through the storage groove 15 for recycling, so as to facilitate the secondary recycling of the scraps.

[0021] As shown in the attached drawings of the specification Figure 2 、 4As shown, the moving template 12 is a concave plate. A number of pressure monitoring devices 3 are provided on both sides of the open side of the moving template 12. The pressure monitoring devices 3 are connected to the side wall of the moving template 12 by welding. The detachable convex template 14 is located inside the groove of the moving template 12. A stamping telescopic device 4 is provided on the bottom surface of the detachable convex template 14. The output shaft of the stamping telescopic device 4 passes through the bottom surfaces of the moving template 12, the detachable convex template 14 and the fixing plate of the mold frame 1. The output shaft of the stamping telescopic device 4 is connected to the detachable convex template 14 by a thread. The base of the stamping telescopic device 4 is connected to the fixing plate of the mold frame 1 by a bolt structure. Before the stamping operation is carried out on the raw material, the periphery of the raw material is extruded by the two side surfaces of the open end of the moving template 12, so that the raw material will not be deformed inward during stamping, thereby ensuring the quality of the finished product. And the pressure monitoring device 3 is used to detect the pressure received by the periphery of the raw material, so as to avoid cracks at the corners of the finished product caused by overloading of the pressure.

[0022] On one side of the fixing plate of the mold frame 1, there is a control panel 5 for controlling the telescopic device 2 and the stamping telescopic device 4. The stamping telescopic device 4, the telescopic device 2 and the pressure monitoring device 3 are all connected to the control panel 5 by data lines. By uniformly reacting and processing the signals of each device through the control panel 5, timely reaction can be achieved, ensuring the safety of the device during operation.

[0023] When the present invention is specifically implemented, the raw material is placed above the detachable concave template 13. The telescopic device 2 and the stamping telescopic device 4 are simultaneously started through the control panel 5. When the two open side ends of the moving template 12 contact the raw material, the pressure monitoring device 3 will detect the pressure on the raw material (while fixing the raw material, avoiding damage to the raw material due to excessive pressure). When the pressure reaches the peak value, the pressure monitoring device 3 alarms. When the control panel 5 receives the alarm signal, it stops extending the output shaft of the telescopic device 2. At this time, the stamping telescopic device 4 continues to press down, so that the detachable convex template 14 performs the stamping operation (the scraps fall into the scrap recycling box 6 from the storage groove 15 for subsequent secondary recycling). After the stamping is completed, the control panel 5 controls the telescopic device 2 and the stamping telescopic device 4 to return to their original positions and standby. After ensuring that the stamping operation is completed, the finished product is taken out and the raw material is put in for reprocessing.

[0024] The above describes the present invention and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the creative purpose of the present invention, they shall fall within the protection scope of the present invention.
