Demolding mechanism for automobile air conditioner air channel injection mold

Abstract

The invention discloses a demolding mechanism for an automobile air conditioner air channel injection mold. In a mold assembly state, a forming hole of a slider insert (1) is matched with an automobile air conditioner air channel lug (102). A space is arranged between the front end of the slider insert (1) and an automobile air conditioner air channel. The lug (102) of the slider insert (1) is embedded in a notch (2.1). A second side face (1.1.4) of the tail end of the lug (102) abuts against the rear side wall of the notch (2.1). A space D1 is arranged between a first side face (1.1.3) of thefront end of the lug (102) and the front side wall of the notch (2.1). The bottom face of the slider insert (1) is attached to the top face of a locating plate (4). Through the demolding mechanism, the automobile air conditioner air channel can be formed, demolding can be conducted normally, and bulge deformation or cracking of an alcove and pulling damage to a support are avoided.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a demoulding mechanism for an injection mold of an automobile air-conditioning duct. Background technique [0002] Such as figure 1 As shown, the side of the automobile air-conditioning duct is provided with a protruding bracket 101, and the top surface of the bracket 101 is provided with a plurality of protrusions 102. Since the direction of the protrusions is perpendicular to the direction of demoulding, it cannot be directly separated from the upper and lower parts of the mold. If forced demoulding is used, it will cause deformation or breakage of the protrusions, and will also strain the inner bracket. Therefore, there is an urgent need for a demoulding mechanism that can form the automobile air-conditioning air duct, and can be demoulded normally, without causing deformation or breakage of the inner concave table, and without causing strain on the bracket.

[0002] like figure 1 As shown, the side of the automobile air-conditioning duct is provided with a protruding bracket 101, and the top surface of the bracket 101 is provided with a plurality of protrusions 102. Since the direction of the protrusions is perpendicular to the direction of demoulding, it cannot be directly separated from the upper and lower parts of the mold.

If forced demoulding is used, it will cause deformation or breakage of the protrusion, and it will also strain the inner bracket
