Embodiment

[0033] Example: such as Figure 1-8 As shown, a light-weight composite automobile inner door panel is one-time molding processing method. A group of hydraulic clamping mechanisms are set between the fixed mold 1 and the movable mold 2 of the injection mold. The hydraulic clamping mechanism includes The fixed mold hydraulic system 11 and the fixed mold hydraulic ejector pin 12 and the movable mold hydraulic system 21 and the movable mold hydraulic ejector pin 22 arranged on the movable template 2 .

[0034]The fixed mold hydraulic system 11 includes a fixed mold oil cylinder 111 arranged on the fixed mold 1, the fixed mold 1 is provided with a fixed mold oil cylinder fixing plate 13, and the fixed mold oil cylinder 111 is fixed on the fixed mold oil cylinder fixing plate 13 by the fixed mold oil cylinder fixing screw 14 , the piston rod of the fixed mold oil cylinder 111 is connected with the fixed mold ejector backing plate 15 and the fixed mold ejector fixing plate 16 by scre...

Abstract

The invention discloses a one-time forming machining method of a light composite car interior door panel. An injection mold of a special structure is arranged, oil cylinder ejection structures are arranged in a movable die and a fixed die of a plastic die, an overflow valve is cleverly accessed by utilizing different ejection forces of corresponding oil cylinders when the oil cylinders on both sides are oppositely ejected, and dynamic clamping of an organic plate and hot press molding are successfully realized during injection molding and mold closing through the pressure rise change of cylinder bodies and the overflowing effect of the overflow valve during opposite ejection of the oil cylinders on the both sides, so that the one-time forming machining of the composite car interior door panel is realized, the machining efficiency is greatly improved, and the machining cost and the die cost are reduced.

Description

technical field [0001] The invention relates to a processing method of an automobile inner door panel, in particular to a one-time forming processing method 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 mater...
