A filter base shell mold

Abstract

The invention discloses a filter cleaner base shell mould. The filter cleaner base shell mould comprises an upper mould frame, an upper mould core, a lower mould frame and a lower mould core, wherein the upper mould core is arranged in the upper mould frame, and the lower mould core is arranged in the lower mould frame. The upper mould frame and the lower mould frame are connected and arranged on the left side and the right side of the mould correspondingly. A left sliding block and a right sliding block are arranged between the upper mould core and the lower mould core. A left oil cylinder and a right oil cylinder are arranged at the end of the left sliding block and the end of the right sliding block correspondingly. The upper mould core, the lower mould core, the left sliding block and the right sliding block are combined to form a die casting cavity of a filter cleaner base shell. A left side oblique swinging block and a right side oblique swinging block are arranged on the upper mould frame, wherein the left side oblique swinging block is matched with the left sliding block, and the right side oblique swinging block is matched with the right sliding block. Partial cooling devices are arranged on the positions, nearby the die casting cavity, of the left sliding block and the right sliding block correspondingly. The filter cleaner base shell mould has the obvious beneficial effects that structure is simple and stable, cost is low, production efficiency is high, the size of a casting outline is stable, casting quality is good, and the mould is good in heat dissipation effect and high in heat dissipation speed.

Description

technical field [0001] The invention relates to the technical field of die-casting molds, in particular to a die-casting mold for filter base shells. Background technique [0002] Die-casting mold refers to a mold in which liquid metal is poured into the cavity of the mold, and a series of processes such as pressurized forging are used to shape the casting. Due to the complex structure, many castings are difficult to demould after forming. In order to release the castings smoothly, the structure of adding mosaic blocks or sliders is usually used in the die-casting mold, and it is realized by core pulling through the hydraulic cylinder. In the market, many slider core-pulling structures have the problems of high cost, low production efficiency and poor casting quality. However, the structure of the general die-casting mold in the prior art does not effectively solve the above-mentioned problems. For example, the Chinese Patent Authorization Announcement No. CN 203680683 U,...
