Description

Technical Field

[0001] The utility model relates to the technical field of die casting, in particular to a fast dismantling and replacing die casting die. Background Art

[0002] Die casting is a metal casting process, which uses high-temperature liquid metal to press into the mold cavity under high pressure. The structure of the mold cavity is the same as the structure of the product to be formed. After the liquid metal cools and solidifies, the mold is opened and taken out to form the formed product. Since the die-casting mold is designed according to the shape, size and structure of the product, the production of different products often requires the replacement of die-casting molds with different cavity structures. When changing the mold, some existing die-casting molds only use a number of screws to lock the mold core and other parts of the mold into a whole, and then install the mold as a whole on the die-casting machine to produce the product. This method of only using a number of screws for locking connection is not convenient enough when removing and replacing the mold core. When installing and disassembling the mold core, each screw needs to be tightened or loosened one by one, which is slow to operate and affects production efficiency. Utility Model Content
