Molding apparatus for glass fiber reinforced plastic product

Abstract

The invention provides a molding apparatus for a glass fiber reinforced plastic product. The molding apparatus comprises a product female mould, a stirrer and a fan, wherein the product female mould is installed on a female mould support, one end of the product female mould is connected with a driving motor, a demolding air passage is arranged in the product female mould and is connected with the fan through a demolding air faucet, the stirrer is located above the product female mould, the lower end of the stirrer is connected with a sprue of the product female mould through a material guiding pipe, a joint of the material guiding pipe and the stirrer is provided with a solenoid valve, a flowmeter is arranged on the solenoid valve, and the driving motor, the stirrer, the fan and the solenoid valve are all connected with a programmable controller. The molding apparatus for the glass fiber reinforced plastic product has the advantages of a simple structure, automatic operation, capacity of producing glass fiber reinforced plastic product products with same quality and improved production efficiency.

Description

Technical field [0001] The present invention relates to the technical field of glass fiber reinforced plastics, and in particular to a molding equipment for producing glass fiber reinforced plastic products with small size and approximately circular or cylindrical cavity shells. Background technique [0002] Many products in the glass fiber reinforced plastic industry are small in size and approximately round or cylindrical in shape, such as civil protective covers and military radomes. The current production processes are mostly hand lay-up and vacuum processes, which are difficult to operate and have low production efficiency. [0003] Chinese patent document CN203031848U discloses a molding equipment for glass fiber reinforced plastic products (such as figure 1 Shown), including a control system, a main frame, a mold part, a stirrer, and a motor. The bottom of the stirrer is connected to one end of the mixed liquid injection pipeline, and the other end of the mixed liquid inject...

AI Technical Summary

Problems solved by technology

Due to the viscosity of the mixed liquid, the injection pipeline of the mixed liquid in the molding equipment of the above-mentioned FRP products is easily blocked, which affects the working efficiency

In addition, the above-mentioned equipment cannot calculate and control the amount of mixed liquid injected into the female mold of the product, resulting in inconsistent quality of the produced glass products, which is not suitable for mass production
