Description

Technical Field

[0001] This utility model relates to the field of foamed silicone sheet technology, and in particular to a foamed silicone sheet stamping equipment. Background Technology

[0002] The foamed silicone sheet stamping equipment is a mechanical device used to press foamed silicone material through a mold to form products of the required shape and size. It plays a vital role in the production of silicone products, especially in the production of silicone buttons, silicone sealing rings and silicone shock absorbers.

[0003] When stamping silicone foam sheets, the stamping plate needs to be heated first. After stamping, the stamping plate is lifted quickly, which causes the silicone material to lose pressure support in a short time, resulting in a large rebound. This affects the accuracy and shape stability of the stamped parts. In addition, when the stamping plate is lifted quickly, the silicone is easy to stick to the stamping plate due to the high temperature, which requires manual removal by workers, which is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide a stamping equipment for foamed silicone sheets to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foamed silicone sheet stamping equipment, comprising:

In specific use: the stamping plate 6 drives the first trapezoidal block 7 to squeeze the second trapezoidal block 8 to move, stretching the elastic mechanism until the first trapezoidal block 7 abuts against the square plate 11. The lifting drive mechanism continues to drive the stamping plate 6 to move, completing the stamping work. When the lifting drive mechanism lifts the square plate 11, the elastic mechanism resets and drives the second trapezoidal block 8 to squeeze the first trapezoidal block 7.
