Description

Integrated injection molding mold for decorative strip on automobile rear door

Technical Field

The utility model relates to an advanced production manufacturing and automatic technical field, concretely relates to automobile-used back door upper decoration strip integrative injection moulding mould.

Background

The automobile trim strip is more and more popular among consumers as a main exterior trim of an automobile, and is widely used on the automobile. The automobile trim is usually made by injection molding and is mounted on the side of the automobile door by means of snap-fit assembly. Injection molding is a process used to mass produce parts of some complex shapes. Specifically, the plastic melted by heating is injected into a mold cavity from an injection molding machine at high pressure, and a formed product is obtained after cooling and solidification. When the existing injection mold is used for processing a special-shaped injection molding part, the cooling performance after injection molding is low, rapid molding cannot be achieved, smooth demolding is not easy to occur during mold opening, the injection molding part is easy to damage by pulling, and the like.

Therefore, the above problems need to be solved.
