Abstract

The invention discloses a foundry casting die assembly comprising a base. The top of the base is provided with a movable disc, the both sides of the movable disc are provided with support plates, a side plate is arranged on the rear side of the base, the top of the side plate is provided with a top plate, a lifting shell is arranged on the bottom of the top plate and the top of the movable disc, the interior of the lifting shell is provided with a top mold, and the two sides of the inner wall of the lifting shell are provided with cooling devices. The foundry casting die assembly is provided with the lifting shell and a vacuum pump, liquid state casting materials are injected into a bottom mold, then a hydraulic lifting rod works to be capable of pushing the lifting shell to descend, protruding blocks are sequentially inserted into grooves in the support plates to make the inside of a space of the lifting shell sealed, and then vacuum pump works to vacuumize the inside of the lifting shell, so that the internal pressure of the lifting shell is at a stable value, it is ensured that the occurrence of pores caused by the fact that the casting materials bear the air pressure effect inthe molding process is avoided, and the quality of products is guaranteed.

Description

technical field [0001] The invention relates to the field of casting technology, in particular to a sand casting die device. Background technique [0002] The manufacturing process of foundry casting is generally to manufacture the sand mold for casting first, then inject the liquid casting material into the sand mold, take out the casting after cooling, arrange (remove the attached sand, arrange the injection hole) or clean, and the casting is completed. Existing molds for foundry casting are generally fixed on the die device, and are not easy to replace after damage, and in the process of casting molding, many pores will appear during the molding process of the liquid casting material due to external air pressure, affecting Therefore, it is necessary to invent a sand foundry die casting device to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a sand foundry die casting device, which is equipped with a lifti...
