Description

Technical Field

[0001] The utility model relates to the technical field of die-casting molds, in particular to a quick demoulding mold for machining mechanical parts. Background Art

[0002] Molds are various tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools used to make molded objects. Mechanical parts often require die-casting molds for molding and manufacturing during processing. Die casting refers to a casting method in which liquid metal is filled into the mold cavity under high pressure and high speed conditions and cooled under high pressure. It is one of the most widely used and fastest-growing metal hot processing forming process methods in the casting process.

[0003] At present, after mechanical parts are die-casted through molds (movable molds and fixed molds), ejectors are often used to eject the mechanical die-casting parts. In order to prevent the mechanical die-casting parts from being deformed during ejection, it is often necessary to wait for the mechanical die-casting parts to cool naturally before ejecting them from the mold. The natural cooling process consumes too much time, which seriously affects the production efficiency of the mechanical die-casting parts. In view of this, we propose a quick demolding mold for mechanical parts processing. Utility Model Content
