Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a stamping die. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts. Appropriate stamping dies are required in the processing of stainless steel kitchenware.

[0003] Existing stamping dies often result in kitchenware products being tightly fitted into the die cavity after stamping due to the stamping pressure, making it difficult for workers to separate them and causing a long retrieval time. This not only affects the processing efficiency of the kitchenware but also leads to low die performance. Therefore, there is an urgent need for a new stamping die to solve these problems.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] like Figures 1-3 As shown, a stamping die in this embodiment includes a lower die base 1, with a die cavity 5 inside the lower die base 1. Kitchenware products are stamped and formed inside the die cavity 5. A recessed cavity 7 is provided on one side of the upper end of the lower die base 1. Two sets of supports 6 are symmetrically installed at one end of the recessed cavity 7. A rotating shaft 9 is installed between the supports 6. A lifting plate 10 is fixed on one side wall of the rotating shaft 9, which can automatically eject the product inside the die cavity 5. A lever 8 is fixed on the other side wall of the rotating shaft 9. Two sets of arc-shaped guide rails 11 are symmetrically arranged on both sides of the lever 8, which can limit and guide the movement of the lever 8. The curvature of the arc-shaped guide rails 11 is consistent with the rotation path of the lever 8. Two sets of guide posts 12 that match the specifications of the arc-shaped guide rails 11 are symmetrically fixed on both sides of the lever 8. A spring 13 is fixed between the guide post 12 and the inner wall of the arc-shaped guide rail 11, which can automatically reset the lever 8.

[0025] like Figures 1-3 In this embodiment, the mold cavity 5 is formed on the lower mold base 1, the concave cavity 7 is formed on the lower mold base 1, the support 6 is welded to the side wall of the lower mold base 1, the rotating shaft 9 is rotatably installed between the supports 6, the lifting plate 10 and the lever plate 8 are symmetrically welded on both sides of the rotating shaft 9, one end of the arc-shaped guide rail 11 is connected to the lower mold base 1 by screws, the lever plate 8 is slidably connected to the arc-shaped guide rail 11 through the guide post 12, and the spring 13 is fixed between the guide post 12 and the inner wall of the arc-shaped guide rail 11. The spring 13 has an arc-shaped structure. When the product needs to be removed after stamping, an external force can be applied to the lever plate 8 to make it move along the arc-shaped guide rail 11 under the action of the rotating shaft 9 and stretch it. At this time, according to the lever principle, the lifting plate 10 can be moved upward to apply an external force to the product and fix it to separate from the mold cavity 5, which is convenient for the workers to unload the material. The lever plate 8 will automatically reset under the action of the spring 13, which can shorten the unloading time, improve the stamping efficiency of the device, and has high performance.

[0026] like Figures 1-3 In this embodiment, an upper mold base 2 with matching mold cavity 5 is provided above the lower mold base 1. Guide cavities 4 are provided at the four corners of the top of the lower mold base 1. Guide rods 3 are fixed at the bottom of the upper mold base 2 at positions corresponding to the guide cavities 4. When the stainless steel plate is placed on the lower mold base 1, the upper mold base 2 moves down under the action of an external driving mechanism to close the mold with the lower mold base 1 and stamp the stainless steel plate, so that it is stamped into the shape of kitchen utensils in the mold cavity 5. During the mold closing process, the guide rods 3 and the guide cavities 4 combine to guide the upper mold base 2 to ensure smooth mold closing.

[0027] The specific implementation process of this embodiment is as follows: First, the lower mold base 1 is fixed and the upper mold base 2 is connected to the external driving mechanism. During use, the stainless steel plate is placed on the lower mold base 1. Under the action of the external driving mechanism, the upper mold base 2 moves down and closes with the lower mold base 1 to stamp the stainless steel plate, so that it is stamped into the shape of a kitchen utensil in the mold cavity 5. During the mold closing process, the guide rod 3 and the guide cavity 4 are combined to guide the upper mold base 2 to ensure smooth mold closing. When the product needs to be removed after stamping, an external force can be applied to the lever plate 8 to make it slide down along the arc guide rail 11 under the action of the rotating shaft 9. At this time, according to the lever principle, the lifting plate 10 can be moved up to apply an external force to the product and separate it from the mold cavity 5, which is convenient for the staff to unload the material. The lever plate 8 will automatically reset under the action of the spring 13, which can shorten the unloading time, improve the stamping efficiency of the device, and has high performance.

[0028] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
