Description

Technical Field

[0001] This utility model relates to the technical field of molds, specifically to a tool changing mechanism and a punching die. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, molds are tools used to make shaped objects. These tools are composed of various parts, and different molds are composed of different parts. They mainly achieve the processing of the shape of the object by changing the physical state of the material being molded. They are known as the "mother of industry." They are tools that make blanks into parts with specific shapes and sizes under the action of external forces. They are widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. Punching dies are molds for punching products.

[0003] In existing technology, the die core, die base, and connecting plate in a punching die are fixedly connected by screws. The die core can only process parts of one shape. When different shapes of parts need to be processed, the die core needs to be replaced. The replacement operation requires adjusting a large number of screws, which is cumbersome, labor-intensive, and time-consuming. This results in a long downtime during punching operations, affecting the normal progress of the punching operation. Utility Model Content

[0004] The purpose of this invention is to provide a tool changing mechanism and a punching die to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides a tool changing mechanism, including a moving mold assembly and a fixed mold base. The moving mold assembly includes a moving mold frame and a moving mold head. The moving mold head has a plate-like structure, with one side being a first cutting surface and the other side being a second cutting surface. The moving mold head is rotatably connected to the moving mold frame, which has a clearance groove. The moving mold head can rotate and pass through the clearance groove so that either the first or second cutting surface faces downward. A fixing block is provided in the clearance groove, and the fixing block abuts against the moving mold head. The fixed mold base is located directly below the moving mold head and opposite it. The fixed mold base has a plate-like structure, with one side being a first support surface and the other side of the moving mold head being a second support surface. The fixed mold base can be flipped so that the first support surface matches the first cutting surface or the second support surface matches the second cutting surface.

[0006] Furthermore, the moving mold head is provided with rotating shafts on both sides, and the rotating shafts are rotatably connected to the moving mold frame.

[0007] Furthermore, the first cutting surface and the first supporting surface are marked with the same color, the second cutting surface and the second supporting surface are marked with the same color, and the first cutting surface and the second cutting surface are marked with different colors.

[0008] Furthermore, this application also provides a punching die, including the aforementioned tool changing mechanism.

[0026] Example 1

[0027] Reference Figure 1 and Figure 2 As an embodiment of the present invention, a tool changing mechanism includes a moving mold assembly 1 and a fixed mold base 13. The moving mold assembly 1 includes a moving mold frame 11 and a moving mold head 12. The moving mold head 12 has a plate structure, one side of which is a first cutting surface 121, and the other side of which is a second cutting surface 122. The moving mold head 12 is rotatably connected to the moving mold frame 11. The moving mold frame 11 is provided with a relief groove 111, and the moving mold head 12 can rotate and pass through the relief groove 111 to allow the first cutting surface 121 or the second cutting surface to be cut. With surface 122 facing downwards, a fixing block 112 is provided in the clearance groove 111, and the fixing block 112 abuts against the moving mold head 12; the fixed mold base 13 is located directly below the moving mold head 12 and opposite to the moving mold head 12. The fixed mold base 13 has a plate structure. One side of the fixed mold base 13 is the first support surface 131, and the other side of the moving mold head 12 is the second support surface 132. The fixed mold base 13 can be flipped so that the first support surface 131 is adapted to the first cutting surface 121 or the second support surface 132 is adapted to the second cutting surface 122.

[0028] When the moving die head 12 rotates to face downwards with the first cutting surface 121 facing down, the fixing block 112 is inserted into the relief groove 111 and abuts against the moving die head 12 to fix it in place. The fixed die base 13 is fixed in the designated position with the first support surface 131 facing upwards, directly opposite the first cutting surface 121. At this time, the moving die head 12 can move downwards to perform a stamping operation. When another type of part needs to be processed, the fixing block 112 is removed, and the moving die head 12 is rotated to face downwards with the second cutting surface 122 facing down. The fixing block 112 is then inserted into the relief groove 111 and abuts against the moving die head 12 to fix it in place. The fixed die base 13 is fixed in the designated position with the second support surface 132 facing upwards, directly opposite the second cutting surface 122. At this time, the moving die head 12 can move downwards to perform a stamping operation for the second type of part. The tool changing mechanism in this application can achieve tool changing and machining of a second type of part without changing the moving mold head 12. It is simple to operate, has a short downtime, and improves the machining efficiency of the parts.

[0029] Specifically, the moving die head 12 has rotating shafts 123 on both sides, which are rotatably connected to the moving die frame 11. The first cutting surface 121 and the first supporting surface 131 are marked with the same color, the second cutting surface 122 and the second supporting surface 132 are marked with the same color, and the first cutting surface 121 and the second cutting surface 122 are marked with different colors. This facilitates differentiation and avoids confusion during tool changing operations, ensuring that the first cutting surface 121 abuts against the first supporting surface 131 or the second cutting surface 122 abuts against the second supporting surface 132. In this embodiment, the tool changing mechanism can perform machining operations on two types of parts without changing the moving die head 12, which is simple to operate, has a short downtime, and improves the machining efficiency of parts.

[0030] Example 2

[0031] Reference Figure 1 and Figure 2 As an embodiment of the present utility model, a punching die includes the tool changing mechanism described in embodiment 1. The tool changing mechanism is described in detail in embodiment 1, so it will not be described again.

[0032] Specifically, the punching die also includes a fixed die assembly 2, which is positioned opposite the moving die assembly 1. The fixed die assembly 2 includes a fixed base 21, and a fixed die seat 13 is mounted on the fixed base 21. The fixed base 21 is provided with a positioning post 22, and the fixed die seat 13 is provided with a positioning hole 133, which is adapted to the positioning post 22. In this embodiment, the positioning hole 133 is slidably connected to the positioning post 22. The positioning hole 133 is a through hole, and the positioning holes 133 on both sides of the fixed die seat 13 can be inserted into the positioning post 22, so that the first support surface 131 or the second support surface 132 can abut against the fixed base 21. By setting the positioning post 22 and the positioning hole 133, the fixed die seat 13 can be accurately positioned.

[0033] Furthermore, the moving mold frame 11 is provided with a guide hole 113, and the fixed mold assembly 2 is provided with a guide post 23, the guide hole 113 and the guide post 23 being adapted to each other. The guide post 23 passes through the fixed base 21 and the fixed mold base 13, and the guide post 23 protrudes from the fixed mold base 13, making it easy to insert into the guide hole 113 of the moving mold frame 11.

[0034] In other embodiments, the positions of the guide hole 113 and the guide post 23 can be interchanged, that is, the guide post 23 is provided on the moving mold frame 11, and the guide hole 113 is provided on the fixed mold assembly 2.

[0035] The process of using the punching die in this embodiment is as follows:

[0036] The moving die head 12 rotates until the first cutting surface 121 faces downward. The fixing block 112 is inserted into the relief groove 111 and abuts against the moving die head 12 to fix the moving die head 12. The fixed die seat 13 is fixed to the designated position of the fixed seat 21 and the first support surface 131 faces upward. The first support surface 131 is directly opposite the first cutting surface 121. At this time, the moving die head 12 can move down to perform stamping operations and realize the processing operation of the first type of part.

[0037] When another type of part needs to be processed, the fixing block 112 is removed, and the moving die head 12 is rotated so that the second cutting surface 122 faces downward. Then, the fixing block 112 is inserted into the relief groove 111 and abuts against the moving die head 12 to fix it. The fixed die base 13 is fixed in the designated position with the second support surface 132 facing upward, and the second support surface 132 is directly opposite the second cutting surface 122. At this time, the moving die head 12 can move down to perform the stamping operation of the second type of part.

[0038] In this embodiment, the punching die can process two types of parts without changing the moving die head 12. The operation is simple, the downtime is short, and the processing efficiency of the parts is improved.

[0039] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
