Abstract

The invention discloses an injection mold for one-time molding of a light composite automobile inner door plate. The injection mold comprises a fixed mold and a movable mold, and is characterized in that at least one group of hydraulic clamping mechanism is arranged between the fixed mold and the movable mold of the injection mold, and is used for clamping and fixing an organic plate to be formedin the mold closing process. The injection mold has the following advantages that at least one set of hydraulic clamping mechanism is arranged between the fixed mold and the movable mold of the injection mold and used for clamping and fixing an organic plate to be formed in the mold closing process; and during mold closing, the to-be-formed organic plate does not fall off after leaving a manipulator of an injection molding machine until mold closing is completed, the to-be-formed organic plate is subjected to compression molding between the movable mold and the fixed mold of the injection mold, and at the moment, composite forming of the light composite automobile inner door plate can be completed only by normally entering an injection molding procedure of the injection molding machine.

Description

technical field [0001] The invention relates to the processing of an automobile inner door panel, in particular to an injection mold for one-time molding of a lightweight composite automobile inner door panel. Background technique [0002] The development of automotive interior door panels has gone through three stages: aluminum alloy die-casting door panels, sheet metal stamping door panels and the current plastic PP long-wave fiber injection molding door panels. With the increasingly fierce competition in the market, new technologies and new materials are beginning to be used in the development of automotive inner door panels. The development of automotive inner door panels will enter the fourth stage. Organic sheet (organo sheet) + plastic PP long-wave fiber composite molding door panel , that is to say, a considerable part of the inner door panel is replaced by organic sheet material instead of plastic. [0003] Organic sheet, which is what we call carbon fiber material...
