Self-cooling system in lifting process of casting upper die

Abstract

The invention discloses a self-cooling system in the lifting process of a casting upper die. The self-cooling system comprises an upper die plate, an upper die base plate, a pressing rod, a spring, acore rod, a tool bit and a core rod sleeve; and the upper die base plate is arranged on the lower part of the upper die plate, the pressing rod is arranged at the centers of the upper die plate and the upper die base plate, the spring is arranged at the center of the upper die base plate to sleeve the pressing rod in a circle mode, the core rod sleeve is arranged on the lower part of the upper diebase plate, the core rod is arranged at the center of the core rod sleeve, the upper end of the core rod abuts against the spring, the tool bit is fixed to the lower end of the core rod, the core rodsleeve is provided with a liquid inlet pipeline, the core rod is provided with a cooling liquid channel corresponding to the liquid inlet pipeline, and the cooling liquid channel hinders or communicates with the liquid inlet pipeline along with rising and falling of the core rod. According to the self-cooling system, the cooling procedure is additionally set on the basis of the normal die castingprocedure, but the additional time is not occupied; the normal procedure is die down-pressing, die rising and casting moving away, when a die rises, the cooling procedure is completed through a clever internal structure, the cooling and carrying link in the prior art is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of die casting, and in particular relates to a self-cooling system in the lifting process of an upper mold of a casting. Background technique [0002] Die casting is a very common process in machining. Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into the pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, it is polished and other subsequent processing methods , the resulting object has a certain shape, size and performance. The cooling link is indispensable in the casting process. Usually, the finished casting is transported to a cooling pool for cooling. This method increases the time of transport handling. Therefore, we design a self-cooling system during the lifting process of the casting upper mold. Contents of the invention [0003] Aiming at the requirements of the prior art, a self-c...
