Vehicle door sheet injection mold demolding mechanism

Abstract

The invention discloses a vehicle door sheet injection mold demolding mechanism. The vehicle door sheet injection mold demolding mechanism is characterized by comprising a first inclined ejector block, a second inclined ejector block and a third inclined ejector block fixed at the top end of an inclined ejector rod; the first inclined ejector block, the second inclined ejector block and the thirdinclined ejector block form one part of the bottom surface of a mold injection molding cavity; the first inclined ejector block is positioned below the second inclined ejector block, and the bonded surface of the two is a first inclined surface; an included angle between the first inclined surface and a lower template is 35-45 degrees; the third inclined ejector block is positioned below the second inclined ejector block; the first inclined ejector block, the second inclined ejector block and the third inclined ejector block are twice demolded; in primary demolding, the first inclined ejectorblock and the second inclined ejector block are upwards inclined to separate from the inner side surface of a buckle and a projection; and in secondary demolding, the first inclined ejector block, thesecond inclined ejector block and the third inclined ejector block are upwards inclined to totally separate from the buckle from a first cavity. The mechanism can mold vehicle door sheets, and can perform normal demolding without causing deformation of the projection and scratch of the buckle.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a demoulding mechanism for injection molds of automobile door panels. Background technique [0002] The car door panel is installed on the inner side of the car door. The edge of the top of the door panel body is a curved surface. A buckle 102 is provided at the bottom surface 101 of the curved surface. The clip 102 is roughly perpendicular to the straight edge of the bottom surface 101. A protrusion 102 is provided on the top of the free end portion of 102, and the protrusion 102 is triangular in shape. Since the buckle 102 has a protrusion 103, if a common injection mold and a conventional auxiliary demoulding mechanism are adopted, it cannot be inclined to demould along the length direction of the buckle, because the protrusion 103 will be blocked. If forced demoulding is adopted, the protrusion 103 will be deformed and the buckle 102 will be strained. So there is an...

AI Technical Summary

Problems solved by technology

Since there is a protrusion 103 on the buckle 102, if a common injection mold and a conventional auxiliary demoulding mechanism are adopted, the stripping cannot be inclined along the length direction of the buckle, because the protrusion 103 will be stuck

If forced demoulding is adopted, the protrusion 103 will be deformed, and the buckle 102 will be strained simultaneously.
