Background technique

Alloy products are common daily necessities. Due to their advantages of high strength, good durability and strong assembleability, alloy products are widely used in household products, medical equipment, building materials, sports equipment and other fields. In the production process of alloy products, the alloy material in the molten state is usually stirred evenly at a certain temperature, and then injected into the die-casting mold. The alloy material is formed in the cavity of the die-casting mold, and the formed alloy product is obtained after cooling and solidification. Then the alloy product is pushed out of the die-casting mold by the thimble.

Due to the strong adsorption force in the cavity after the die-casting is formed, the ejection mechanism of the common die-casting mold is composed of several thimbles, and most of the thimbles are small in size and easy to break, so it is not easy to demould.
