Description

Die casting die for sleeve beer Technical Field The utility model relates to the technical field of dies, in particular to a die casting die for a sleeve beer. Background ‌ Beer die casting die ‌ is a die for manufacturing metal parts and is mainly used for completing a die casting process on a die casting machine. Die casting is the process of injecting liquid or semi-liquid metal under high pressure into a mold cavity and rapidly solidifying under pressure to obtain a casting. When in production, a part of metal sleeve can be manufactured firstly, then the metal sleeve is put into a mould, and then the metal sleeve is subjected to compression casting and wrapping by using a die casting process. Some parts in the market are manufactured by a beer sleeve die casting process, such as a gas valve, an automobile oil valve, an exhaust valve and the like, a plurality of mold cores can be needed in the die casting process of the products, and part of the mold cores are arranged on a row position, however, the sealing performance of the mold is high. Meanwhile, due to the fact that the plurality of rows are arranged, air tightness is not well controlled, and the condition that a mold leaks air during mold closing can exist. For example, the Chinese patent application number CN201010618913.1 discloses a die casting die for manufacturing an automatic pump valve body of a gasoline engine, and particularly discloses a sliding block demoulding device which comprises an oil cylinder, a sliding block and a connecting block connected with the sliding block, wherein the oil cylinder is fixed on a movable die plate and is in driving connection with the sliding block, the connecting block is formed with a core corresponding to a long hole position of the valve body, and a lateral core pulling mechanism is arranged between the sliding block and a fixed die plate. The design is actually provided with a plurality of actions to realize the steps of core pulling, demoulding and the like, the tightness during mould closing is not well controlled, and the problem of air leakage possibly exists. And as for the die casting die with large-angle core pulling of CN202020818847.1, the die casting die is provided with a plurality of slide mechanisms, the tightness during die assembly is not well controlled, and the problem of air leakage is possibly caused. In particular, the large-angle core pulling mechanism is not provided with an additional limiting device, and the problem of mold air leakage can exist during die casting.
