Abstract

The invention relates to the field of casting and provides a die-casting mould for an automobile filter shell body. The die-casting mould for the automobile filter shell body comprises an upper mould provided with a mold cavity, a lower mould provided with a mold core, a casting system communicating with the mold cavity and an air vent. The die-casting mould for the automobile filter shell body further comprises an annular cooling assembly and a point-mode cooling assembly which are arranged on the outer side of the side periphery of the mold cavity. A die-casting method is used for casting the automobile filter shell body, and the annular cooling assembly and the point-type cooling assembly are used for cooling, so that the temperature is uniform at the time of forming, crystals of a cast piece is fine, the cast piece is good in compactness, and the air hole detect is not prone to occurring.

Description

technical field [0001] The invention relates to the field of casting, in particular to a die-casting mold for an automobile filter housing. 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...
