Injection mold for door scuff strips

Abstract

The invention discloses a plastic injection mold for a rubbing strip of a car door. The plastic injection mold comprises an upper template (1), a lower template (2), a mold foot (3), a product (4), a pushing plate (14) and a sprue, wherein the lower template (2) is arranged on the mold foot (3) and positioned between the upper template (1) and the mold foot (3); the pushing plate (14) is matched with the interior of the mold foot (3) in a sliding manner; an upper mold cavity is formed in the lower surface of the upper template (1); a lower mold cavity is formed in the upper surface of the lower template (2); a cavity for forming the product (4) is formed between the upper mold cavity and the lower mold cavity; a plurality of first clamping grooves (5) are formed in the bottom surface of the product (4); and a bulge (6) and second clamping grooves (7) distributed on two sides of the bulge (6) are formed on the inner surface of the left side of the product (4). The plastic injection mold for the rubbing strip of the car door has low probability of straining the product, and is high in reliability and small in space occupation.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to an injection mold used for a car door anti-scratch strip. Background technique [0002] Many car models are equipped with door anti-scratch strips. The door anti-scratch strips of mid- and low-end cars are mainly anti-scratch, mainly functional, and the surface is painted or leather-grained; the door anti-scratch strips of some models are also decorated. Function, the surface is electroplated or painted; most high-end cars are mainly used for decoration and are widely used. The anti-scratch strip of the car door is mainly realized by injection molding. According to the existing technology, the long strip of the anti-scratch strip of the car door has high requirements on the surface of the product The deformation of the product is large during injection molding. There are ribs, buckles and undercut surfaces on both sides of the door anti-scratch strip. When the core is pulled, it is...

According to the existing technology, the long strip of the anti-scratch strip of the car door has high requirements on the surface of the product The deformation of the product is large during injection molding. There are ribs, buckles and undercut surfaces on both sides of the door anti-scratch strip. It is easy to strain the product when pulling the core, and the reliability is low. At the same time, there are multiple Card slots with horizontal openings require horizontal core pulling, which takes up a lot of space
