Abstract

The invention relates to cast moulds, in particular to a detachable mould for manufacturing an oil pump plunger sand mould. The detachable mould comprises a bottom mould, wherein the bottom mould comprises a bottom plate, a mould core piece and a core taking piece; a blind hole, corresponding to the mould core piece in size, is formed in the bottom plate; the mould core piece is positioned in the blind hole and the mould core piece and the blind hole are arranged in a split manner; the core taking piece is connected with the outer side wall of the mould core piece. The detachable mould has the benefits that the production efficiency is improved, the production cost is reduced and economic benefits are increased.

Description

technical field [0001] The invention relates to a casting mold, in particular to a detachable mold for making an oil pump plunger sand mold. Background technique [0002] Sand casting is a kind of casting process. The mold used in sand casting is generally composed of outer sand mold and core. Because the molding materials used in sand casting are cheap and easy to obtain, the casting mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings. It has been the basic process in casting production for a long time. [0003] Sand casting molds are used in sand casting, and the sand casting molds are obtained by processing the casting sand in the molding equipment. The molding mold of the current sand casting mold of the oil pump plunger includes a side mold and a bottom mold. A plunger-shaped mold core is made on the bottom mold, and then the casting sand is filled in the mold and compacted. When the sand body r...
