Composite material hot-press forming device

Abstract

The invention relates to a composite material hot-press forming device. The composite material hot-press forming device comprises a suction cup end picker arranged on one side of the device, a feeding device, a manipulator mechanism, a hearth, a moving mechanism, a forming device and a discharging device, wherein the feeding device comprises a panel and a first driving mechanism, the panel is arranged below the suction cup end picker and used for providing resin fiber sheets, and the first driving mechanism is used for driving the panel to move upwards; the manipulator mechanism is arranged on the other side of the device and is used for grabbing the resin fiber sheets; the hearth is arranged in the middle of the device; one side of the moving mechanism is located on the lower side of the suction cup end picker, the other side of the moving mechanism is located on the lower side of the manipulator mechanism, and the moving mechanism is used for conveying away the resin fiber sheets placed in by the suction cup end picker through the manipulator mechanism after the resin fiber sheets are heated by the hearth; the forming device is arranged on one side of the manipulator mechanism and used for performing injection molding of the resin fiber sheets; and the discharging device is arranged on one side of the forming device, and is used for transporting formed products, and the carrying time is shortened. The composite material hot-press forming device has the advantages that the forming time can be shortened, the die assembly pressure can be reduced, the compatibility with injected resin can be improved, the product performance can be enhanced, and continuous operations can be achieved.

Description

technical field [0001] The invention relates to the field of composite material forming, in particular to a composite material hot pressing forming device. Background technique [0002] With the continuous improvement of automobile lightweight requirements, composite materials impregnated with resin and reinforced phase fibers are continuously used in the automobile industry. Composite compression molding composite molding method is suitable for mass production and attracts attention. [0003] The first composite molding method of composite materials, first, in the mold cavity that includes a pair of lower mold (concave mold) and upper mold (convex mold) that can be opened and closed, the reinforcing phase fiber and the resin blank in molten state are placed . After the mold is closed, the resin is impregnated into the reinforcing substrate. Then, by hardening the resin inside the mold cavity, a composite material is obtained. This molding method needs to use a press to ...

AI Technical Summary

Problems solved by technology

The preforming of the fiber sheet requires a preforming mold for preforming. The press must be used to apply a high clamping pressure to close the mold, and multiple sets of molds are required. The corresponding equipment cost becomes higher. The preformed fiber sheet The temperature is so low that the injection resin and the preformed fiber sheet cannot be well fused after closing the mold, resulting in a decrease in reinforcement performance
