Technical Field

[0001] This utility model relates to the field of molding die technology, and in particular to a feeding mechanism for compression molding die. Background Technology

[0002] Compression molding dies are tooling equipment specifically designed for compression molding processes. In the compression molding process, pre-treated material is first placed into the cavity of the mold, and then pressure is applied to make the material form and solidify in the cavity. The shape and size of the mold determine the shape and size of the final product.

[0003] After the existing compression molding mold completes the molding in the cavity, the worker usually needs to manually remove the product from the cavity. During the material removal process, the worker's hands will directly enter the dangerous area of ​​the molding machine. Since the worker usually needs to perform repetitive hand movements when operating the molding machine, these repetitive movements will lead to muscle and nerve fatigue, thereby reducing the worker's judgment and reaction speed, and ultimately increasing the risk of worker's hand injury.
