Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an improved automobile wiring harness shell injection mold. Background Art

[0002] Injection mold generally refers to injection molding, which is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of colors and patterns, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into complex-shaped parts. Injection molding is suitable for mass production and molding processing fields such as complex-shaped products, and is an indispensable part of modern industrial production.

[0003] Most of the inclined guide pins in existing injection molds are directly inserted into the slider below at an angle. When the automobile wiring harness shell is injection-molded, several inserts (i.e., inserts of the upper mold) are also inserted into the molding cavity on the lower mold, so that the automobile wiring harness shell can be formed in the cavity after injection molding. After the automobile wiring harness shell is molded, if the inclined guide pins are directly pulled out at an angle, it will easily cause damage to the inserts and the automobile wiring harness shell, affecting the quality of the product molding.

[0007] Through the design of the upper part of the inclined guide column being vertical and the lower part being inclined, after the automobile wiring harness housing is injection molded, when the upper and lower molds are opened, the vertical part of the inclined guide column on the upper mold is first pulled up in the slider, thereby vertically pulling up several plug-in columns inserted in the automobile wiring harness housing, avoiding damage to the automobile wiring harness housing caused by oblique pulling out.

[0008] Preferably, the upper portion of the inclined guide column is vertical and the lower portion is inclined, and the inclined guide column is installed in the sliding block through the vertical groove and the guide inclined groove.

[0009] Preferably, the upper die and the lower die cooperate with each other.

[0010] Preferably, the injection port is opened through the upper mold.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. Through the design of the upper part of the inclined guide column being vertical and the lower part being inclined, after the automobile wiring harness housing is injection molded, when the upper and lower molds are opened, the vertical part of the inclined guide column on the upper mold is first pulled up in the slider, thereby vertically pulling up the insert inserted in the automobile wiring harness housing, avoiding the inclined guide column being directly pulled out obliquely, which may damage the insert and the automobile wiring harness housing. Finally, the inclined part of the lower part of the inclined guide column drives the slider to move, thereby ejecting the automobile wiring harness housing. BRIEF DESCRIPTION OF THE DRAWINGS
