[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] A punching machine for forming household appliance parts that facilitates demoulding comprises a base 1 and a top seat 2 that are fixedly connected. A punching chamber 5 and a push cylinder 15 are fixedly connected to the inner surfaces of the opposing surfaces of the base 1 and the top seat 2, respectively. A punching plate 3 is fixedly connected to the output end of the push cylinder 15. A linkage rod 8 and a vertical rod 4 are slidably connected to the inner surface wall of the base 1. A lifting plate 6 and a bottom plate 9 are fixedly connected to both sides of the vertical end of the linkage rod 8. An elastic component is provided between the top of the bottom plate 9 and the bottom of the base 1 to maintain the vertical position of the bottom plate 9. The top of the vertical rod 4 is fixedly connected to the punching plate 3, and the bottom of the vertical rod 4 is in transmission cooperation with the bottom plate 9.

[0025] After the part is placed on the lifting plate 6, the cylinder 15 is pushed to drive the stamping plate 3 downward. The stamping plate 3 is linked to the convex plate 7 by the vertical rod 4. The spring 14 is gradually reset and pushes the bottom plate 9 and the side frame 10 downward synchronously. The bottom plate 9 drives the lifting plate 6 downward through the linkage rod 8 until the lifting plate 6 abuts against the inner wall of the base 1. Then the stamping plate 3 drives the vertical rod 4 to continue to move downward, and the convex plate 7 is completely separated from the side frame 10 until the stamping plate 3 is combined with the stamping bin 5 and the stamping forming of the part is completed. The bottom of the lifting plate 6 fits the inner wall of the base 1 to ensure the bearing capacity of the lifting plate 6. Similarly, as the stamping plate 3 rises, the convex plate 7 follows the vertical rod 4 to move up a specified distance. The convex plate 7 drives the bottom plate 9 upward through the cooperation with the side frame 10. The spring 14 is compressed, and the bottom plate 9 drives the lifting plate 6 and the stamped parts upward through the linkage rod 8, thereby achieving stable stamping of home appliance parts while achieving rapid demoulding of the stamped parts.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, the cross-section of the linkage rod 8 is a rectangular structure, and the bottom of the linkage rod 8 is fixedly connected to the bottom plate 9 by a locking rod 11. The locking rod 11 connected between the linkage rod 8 and the bottom plate 9 can be separated. At this time, the lifting plate 6 and the linkage rod 8 can be moved from above the base 1. This ensures the bearing capacity of the lifting plate 6 while allowing the lifting plate 6 to be conveniently disassembled and assembled according to usage requirements, thereby improving the convenience of using a stamping machine for forming home appliance parts that is easy to demold. A rubber pad 12 is interference fit at the bottom of the bottom plate 9, and the inner wall of the rubber pad 12 abuts against the outer wall of the locking rod 11. The interference fit ensures that the position of the rubber pad 12 itself is stable, and the friction generated between the rubber pad 12 and the locking rod 11 can limit the loosening of the locking rod 11.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the elastic component includes a shock absorber 13 and a spring 14, which are fixedly connected between the base 1 and the bottom plate 9. The spring 14 maintains the vertical position of the bottom plate 9 while retaining the vertical telescopic characteristics of the bottom plate 9. The shock absorber 13 prevents the bottom plate 9 from continuously shaking. There are two groups of shock absorbers 13 and springs 14, and the two groups of shock absorbers 13 and springs 14 are distributed on both sides of the horizontal end of the linkage rod 8 to ensure that the bottom plate 9 is evenly stressed. The outer wall of the vertical rod 4 is slidingly connected to the side frame 10 fixedly connected to the bottom plate 9, and the bottom of the vertical rod 4 is fixedly connected to the convex plate 7. As the stamping plate 3 rises, the convex plate 7 follows the vertical rod 4 to move up a specified distance. The convex plate 7 drives the bottom plate 9 upward through the cooperation with the side frame 10, and the spring 14 is compressed. The bottom plate 9 drives the lifting plate 6 and the stamped parts to move upward through the linkage rod 8.

[0028] Working principle: Place the parts on the lifting plate 6, push the cylinder 15 to drive the stamping plate 3 downward, the stamping plate 3 is linked to the convex plate 7 through the vertical rod 4, the spring 14 is gradually reset and pushes the bottom plate 9 and the side frame 10 to move downward synchronously, and the bottom plate 9 drives the lifting plate 6 downward through the linkage rod 8 until the lifting plate 6 abuts against the inner wall of the base 1, then the stamping plate 3 drives the vertical rod 4 to continue to move downward, and the convex plate 7 is completely separated from the side frame 10, until the stamping plate 3 is combined with the stamping bin 5 and the stamping of the parts is completed. The bottom of the lifting plate 6 fits with the inner wall of the base 1, ensuring the carrying capacity of the lifting plate 6. Similarly, as the stamping plate 3 rises, the convex plate 7 follows After the vertical rod 4 moves up a specified distance, the convex plate 7 drives the bottom plate 9 to move up by cooperating with the side frame 10, the spring 14 is compressed, and the bottom plate 9 drives the lifting plate 6 and the stamped parts to move up through the linkage rod 8, thereby achieving stable stamping of home appliance parts while achieving rapid demoulding of the stamped parts, and separating the locking rod 11 connected between the linkage rod 8 and the bottom plate 9. At this time, the lifting plate 6 and the linkage rod 8 can be separated from the base 1. While ensuring the bearing capacity of the lifting plate 6, the lifting plate 6 can be conveniently disassembled and assembled according to usage requirements, thereby improving the convenience of using the stamping machine for forming home appliance parts that are easy to demould.
