Description

A multi-part large-angle automobile hollow plastic pipe mold

technical field

The utility model belongs to the field of injection molding moulds, in particular to a multi-part large-angle automobile hollow plastic pipe mould.

Background technique

Injection molding is a processing method used in the mass production of some parts with complex shapes. Specifically, it refers to injecting heated and melted materials into the mold cavity under high pressure, and after cooling and solidifying, molded products are obtained. The injection mold is mainly composed of two parts, the movable mold and the fixed mold. The movable mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed mold fixed plate of the injection molding machine. The movable mold and the fixed mold are closed during injection molding. The pouring system and the cavity, when the mold is opened, the movable mold and the fixed mold are separated, and then the plastic product is pushed out through the pushing mechanism to take out the plastic product.

Existing hollow plastic pipes are molded with one part during injection molding, and two parts need two sets of molds to be produced separately, and then to be processed later, which wastes mold cost, equipment cost, storage cost and personnel cost. However, when two large-angle hollow plastic pipes with arc-shaped bending sections are processed by one mold, it is inconvenient to demould the parts.
