Injection mold for upper shell of automobile air filter

Abstract

The invention discloses an injection mould for an upper housing of a car air filter. The injection mould comprises a fixed mould assembly (1), a movable mould assembly (2), a lateral loose core device (3) and an oblique loose core device (4), wherein the fixed mould assembly comprises a fixed mould seat plate (11), a fixed mould plate (12) and a cavity (13); the movable mould assembly comprises a movable mould seat plate (21), a movable mould supporting plate (22), a movable mould plate (23), a cavity (24) and a mould pushing device (25); the lateral loose core device comprises a telescopic push-pull mechanism (31), a mounting plate (32) and a lateral loose core (24); the oblique loose core device comprises a wedge-shaped supporting plate (41), a supporting baffle (42), a traction mechanism (43) and an oblique loose core (44). According to the injection mould, mutually staggered plastic parts along the loose cores can be conveniently manufactured and repaired, easily damaged parts can be conveniently replaced, the service life of the mould can be prolonged, the precision of the plastic parts can be guaranteed, and the maintenance expense of the mould can be reduced.

Description

technical field [0001] The invention relates to an injection mold, in particular to an injection mold for an upper casing of an automobile air filter, and belongs to the technical field of injection molding. Background technique [0002] The function of the air filter on the car is to provide clean air for the engine, preventing the engine from inhaling air with impurity particles and increasing the probability of abrasion and damage. The external structure that needs to be protected, in order to suppress the intake noise, generally increase the volume of the air filter housing or arrange a partition in the air filter housing to reduce resonance, in order to achieve the goal in a limited installation space The optimal effect will inevitably result in irregular shapes of the air filter housing, which also increases the difficulty of processing the air filter housing. [0003] In the prior art, the automobile air filter housing is generally formed by one-time injection moldin...

AI Technical Summary

Problems solved by technology

[0005] The existing one-mold and two-cavity injection molds in the actual production process of the upper shell of the automobile filter, especially for injection molds with complex structures with different core-pulling directions and core-pulling directions interlaced, the structure and manufacturing process It is more complex, inconvenient to maintain, and difficult to replace vulnerable parts, which makes it difficult to ensure the accuracy requirements of plastic parts, and the service life of the mold is short; the production cost is high, and the maintenance cost of the mold is high
