[0002] In the conventional process arrangement, facing the punching requirements of two different angles in two different areas, since they are usually located in the same plane, the traditional method is to arrange the punching operations of the two areas to different processes to complete. This method often leads to the increase of the number of die sets, because each process needs an independent die set. More inconveniently, when multiple direction punching is needed at the same position, since only one direction hole can be punched at a time, these different direction punching operations must be allocated to different processes, which undoubtedly increases the number of punching processes. This dispersed process not only increases the development cost of the die, but also increases the production cost of the workpiece, because each additional process means more time and resource investment.

[0021] In one embodiment, as shown in Figures 1-4 A compact structure satisfying different angle side punching at the same time in smaller space, including hoisting tenon unit 1, lower tenon unit 2, driving block 3, lower die holder 4 and upper die holder 5, the upper die holder 5 lower end sliding installation has hoisting tenon unit 1, the driving block 3 and lower tenon unit 2 are matched, the lower tenon unit 2 and hoisting tenon unit 1 are matched, and the upper die holder 5 and driving block 3 are connected with the output end of external cylinder, the driving block 3 is located at the rear of hoisting tenon unit 1, and the lower tenon unit 2 is slidingly installed on the upper end of lower die holder 4.

[0022] The hoisting tenon unit 1 includes hoisting tenon body 11, punch one 12 is arranged on the hoisting tenon body 11, and bottom inclined block 14 is fixed to the bottom of the hoisting tenon body 11.

[0023] The lower tenon unit 2 includes lower tenon body 21, punch two 23 is arranged on the lower tenon body 21, and top inclined block 24 matched with bottom inclined block 14 is fixed to the top of the lower tenon body 21.

[0024] In the embodiment, the external cylinder pushes the upper die holder 5 and the driving block 3 to move downward, the driving block 3 first contacts the lower tenon unit 2, pushes the lower tenon unit 2 to move along the working direction, the lower tenon unit 2 continues to move, contacts the hoisting tenon unit 1 that has moved downward, and pushes it to move along the working direction, and punch one 12 and punch two 23 perform side punching operation in the moving process.

[0025] In an alternative embodiment, the lower die seat 4 comprises a bottom plate 41 and side slot blocks 42 symmetrically fixed on both sides of the upper end of the bottom plate 41, and the side blocks 22 are slidably arranged in the side slot blocks 42, and the side blocks 22 are fixed with the lower tenon body 21, and the lower tenon body 21, the bottom plate 41 and the side slot blocks 42 are designed in an inclined structure with the front end being higher than the rear end.

[0026] It should be noted that the lower tenon unit 2 slides in the side slot blocks 42 of the lower die seat 4 through the side blocks 22, which ensures the stability of the movement. The lower tenon body 21, the bottom plate 41 and the side slot blocks 42 are designed in an inclined structure with the front end being higher than the rear end, which is designed to ensure that when the driving block 3 is lifted after the side punching operation is completed, the lower tenon body 21 can slide backward along the guide of the side slot blocks 42 by its own gravity until it is reset to the initial position.

[0027] In an alternative embodiment, the upper die seat 5 comprises a fixed block 51, a connecting block 52 fixed to the bottom of the rear side of the fixed block 51, a guide rod 53 fixedly connected with the connecting block 52, a hoisting tenon body 11 slidably arranged with the guide rod 53, a spring cavity 15 formed in the hoisting tenon body 11, a fixed plate 54 slidably arranged in the spring cavity 15, the fixed plate 54 being fixed with the guide rod 53, a reset spring 55 fixedly connected to the rear end of the fixed plate 54, the rear end of the reset spring 55 being fixed to the inner wall of the spring cavity 15, and L-shaped guide blocks 56 symmetrically fixed to both sides of the fixed block 51 and matched with the guide grooves 13.

[0028] It should be noted that the stable sliding of the hoisting tenon unit 1 on the upper die seat 5 is ensured by the guide rod 53, the guide groove 13 and the L-shaped guide block 56. The hoisting tenon body 11 is provided with the spring cavity 15, in which the fixed plate 54 fixed with the guide rod 53 is slidably arranged, and the rear end of the fixed plate 54 is tightly connected with the reset spring 55, and the other end of the reset spring 55 is fixedly connected to the inner wall of the spring cavity 15, so that when the hoisting tenon unit 1 is separated from the lower tenon unit 2 after the side punching operation is completed, the hoisting tenon unit 1 can be reset under the elastic force of the reset spring 55.

[0029] In an alternative embodiment, the axis of the punch one 12 is not parallel to the axis of the punch two 23.

[0030] It should be noted that the axis of the punch one 12 is not parallel to the axis of the punch two 23, which can realize punching operation at different angles or in different directions. The specific angle or direction between the axis of the punch one 12 and the axis of the punch two 23 can be adjusted as needed.

[0031] The above embodiment discloses a compact structure that meets different angle side punching at the same time in a small space. When the external cylinder starts to work, it pushes the upper die holder 5 and the driving block 3 to move downward together. The driving block 3 first contacts the lower inclined tenon unit 2 and pushes the lower inclined tenon unit 2 to move along the working direction.

[0032] With the continuous movement of the lower inclined tenon unit 2, the top inclined block 24 of the lower inclined tenon unit 2 contacts the bottom inclined block 14 of the hoisted inclined tenon unit 1 that has moved downward, and pushes the hoisted inclined tenon unit 1 to move along the same working direction. In this process, the punch one 12 of the hoisted inclined tenon unit 1 and the punch two 23 of the lower inclined tenon unit 2 contact the workpiece and perform side punching operation.

[0033] When the side punching operation is completed, the external cylinder stops working and starts to rise. Due to the inclined design of the lower inclined tenon unit 2, the bottom plate 41 and the edge groove block 42, the lower inclined tenon unit 2 slides backward along the guide of the edge groove block 42 under the action of its own gravity until it is reset to the initial position. At the same time, the hoisted inclined tenon unit 1 is also reset along the guide structure (guide rod 53, guide groove 13, L-shaped guide block 56, etc.) of the upper die holder 5 under the elastic force of the reset spring 55.

[0034] The technical solution of the present application only relates to the corresponding inclined wedge mechanism. Other components of the mold are not included in the improved technical solution of the present application. Therefore, in the present embodiment, other corresponding components of the mold are not introduced. However, those skilled in the art are aware of the basic structure of the mold and the connection or action relationship between the parts.

[0035] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be covered within the protection scope of the present application.
