Abstract
Description
Technical Field
[0001] This utility model belongs to the field of prepreg molding technology, and specifically relates to an auxiliary tooling for molding fiber cloth prepreg. Background Technology
[0002] Compression molding of fiber prepreg is a novel molding process for continuous fiber thermoplastic composite materials. The fiber prepreg is composed of fiber cloth and thermoplastic resin sheets. The entire process involves pre-shearing, edge reinforcement, heating in a tunnel oven, laying, molding, and post-processing of the fiber prepreg.
[0003] The time from when the heated fiber prepreg leaves the oven to when the mold closes needs to be controlled to around 15 seconds to prevent the fiber prepreg from losing temperature and affecting the molding performance. To meet this requirement, the oven typically uses a telescopic conveyor belt, which serves both heating and material spreading functions.
[0004] The accuracy of fiber prepreg placement is particularly important, directly affecting the performance of molded products. Due to the short processing time and the inability to adjust the placement afterward, the precise positioning of the fiber prepreg on one side of the tunnel oven directly impacts subsequent production. Currently, there is no effective auxiliary tooling to achieve accurate placement. Summary of the Invention
[0005] This invention provides an auxiliary tooling for molding fiber cloth prepreg, which can solve the problems pointed out in the background art.

[0007] The prepreg preparation mechanism includes a spreading panel and a positioning component disposed on the spreading panel. The spreading panel is slidably connected to the main frame and is driven to reciprocate along the X-axis of the main frame by a first X-axis drive component.
[0008] The prepreg transfer mechanism includes a Z-axis sliding frame, an X-axis sliding frame, and a gripping device. The Z-axis sliding frame is slidably connected to the main frame and is driven to reciprocate along the Z-axis of the main frame by a Z-axis drive member.
