Abstract

The invention relates to the field of casting, and aims to provide an air filter die casting mould for uniform cold forming. The air filter die casting mould comprises an upper mould body provided with a cavity, a lower mould body provided with a mold core, a pouring system communicating with the cavity and an exhaust passage. The air filter die casting mould for uniform cold forming further comprises an annular cooling assembly and a point cooling assembly which are arranged on the circumferential side of the cavity. An automobile filter housing is cast by die casting, the annular cooling assembly and the point cooling assembly are used for cooling, the difference between temperatures is uniform during forming, castings have fine crystallization and good compactness, and air hole defectsare not prone to occurring.

Description

technical field [0001] The invention relates to the field of casting, in particular to an air filter die-casting die formed by soaking. Background technique [0002] Automobile filters are commonly used auto parts; the outer side of the automobile filter housing has heat-dissipating ribs, and the geometric shape is complex; the invention of Chinese patent application number: CN 201610126065.X discloses an automobile water pump, filter and A one-time casting molding method for a cooler shell, comprising separately manufacturing an upper mold, a lower mold, and a sand core that can be installed in a cavity formed after the upper mold and the lower mold are closed; heating the upper mold and the lower mold to 180 to 240 degrees, and then spray paint on the inner surface of the cavity formed after the upper mold and the lower mold are closed; The second sand core, the third sand core, the fourth, fifth, and sixth sand cores are installed in the cavity of the lower mold, and the...
