Description

Technical Field

[0001] This utility model belongs to the technical field of carbon fiber prepreg molding device, specifically a precise positioning carbon fiber prepreg molding device. Background Technology

[0002] The carbon fiber prepreg molding device lays the cut carbon fiber prepreg into a metal mold cavity according to the layup design, then transfers it to a press to cure and form under certain temperature and pressure. After cooling to a low temperature, the product is taken out.

[0003] A search revealed a patent with publication number CN222201764U: a carbon fiber prepreg molding equipment for easy unmolding, relating to the field of carbon fiber prepreg molding technology. The equipment includes a base and a demolding assembly. The demolding assembly is bolted to the middle of the top of the base. The demolding assembly includes a lower mold base, a guide hole, a central hole, an air chamber, a piston, a connecting rod, a plug, a spring, an air pipe, and an air pump. This application provides a carbon fiber prepreg molding equipment for easy unmolding. Through the demolding assembly, after molding, the carbon fiber prepreg does not adhere to the upper mold base under the action of a release agent, but rather adheres tightly to the central cavity of the lower mold base. The air pump pumps high-pressure air into the air chamber through the output air pipe. Driven by the high-pressure air, the piston drives the plug at the end of the connecting rod to disengage from the central hole in the central cavity, ejecting the molded carbon fiber prepreg from the lower mold base cavity. Automatic unmolding of the carbon fiber prepreg is achieved without manual assistance, improving the automation level of the device.

[0004] The aforementioned equipment sprays the release agent onto the inner surface of the mold by manually squeezing the squeeze bottle and using a rotating swing cylinder. This method is cumbersome and can easily cause the release agent to splash out. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. When using this utility model, start the servo motor to drive the worm gear to rotate in the ear, thereby driving the support arm and the spray plate to rotate together, covering the lower mold with the spray plate. Then start the water pump to send the release agent in the water tank into the spray plate through the hose, spraying it on the inner wall of the lower mold. The spraying is automatic and prevents the release agent from leaking out, making spraying convenient.

[0018] 2. This utility model can measure the temperature of the lower mold through a temperature sensor, start the chiller to cool the cooling water, and then send it into the outer shell through the return pipe to cool the lower mold. After cooling, the water returns to the chiller through the outlet pipe for cooling again. This cycle is repeated to cool and lower the temperature of the carbon fiber prepreg in the lower mold, so that this utility model can play an auxiliary cooling role. Attached Figure Description
