Description

Mould convenient to drawing of patterns Technical Field The utility model relates to the technical field of metal part production, in particular to a die convenient for demolding. Background By producing a pump cap is meant a process of manufacturing a pump cap, which is an important component of the pump, typically mounted on the top or side of the pump, for closing the interior space of the pump, preventing leakage of medium, and serving to support and protect the mechanical components inside the pump. The production pump cover is usually cast molding, in order to be convenient for install the production pump cover, can set up multiunit mounting hole in the edge, at present to the production pump cover mounting hole usually die-cut with integrative cast molding, die-cut is to transfer to die-cut platform truck to die-cut after the casting molding of production pump cover, the operation is comparatively troublesome, many manufacturers select integrative cast molding to go out the mounting hole, but when mounting hole integrative cast molding, enlarged the area of contact of pump cover and mould, the mould drawing of patterns of this kind of structure is comparatively inconvenient.
