Description

Technical Field

[0001] This utility model relates to the field of mold injection technology, specifically to a mold injection device for fiberglass products. Background Technology

[0002] Fiberglass, scientifically known as fiber-reinforced plastic, is commonly called FRP, which stands for fiber-reinforced composite plastic. Depending on the type of fiber used, it is classified into glass fiber reinforced composite plastic (GFRP), carbon fiber reinforced composite plastic (CFRP), boron fiber reinforced composite plastic, etc. It is a composite material that uses glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as reinforcing materials and synthetic resin as the matrix material. Fiber-reinforced composite materials consist of reinforcing fibers and a matrix.

[0003] Chinese Patent CN215703096U discloses a material injection device for fiberglass product molds, including a base, a conveying pump and a support column at the bottom of the base, a material control valve and a conveying pipe at the end of the conveying pump, a drive motor installed on one side of the conveying pump, a ball screw and a spiral conveying shaft on the other side of the conveying pump, a stop bar on the ball screw, a mixing tank at the top of the base, and a controller on the side wall of the mixing tank. This fiberglass product mold injection device features a closed connection between the mixing tank and the tank lid, avoiding the problems associated with traditional open mixing tanks. This facilitates thorough mixing of various added materials. The continuously increasing pressure from the spiral conveying shaft causes any unmixed materials to undergo secondary pressure rolling friction and kneading, thus preventing unmixed materials from being conveyed into the mold. The material control valve allows for easy adjustment of material output according to different molds, avoiding waste. The device has a simple and reasonable structure, is easy to use, effectively solves many existing problems, and has high practical value.

[0004] However, the above technical solution has the following shortcomings: during use, a large amount of raw materials tend to adhere to the outside of the screw conveyor shaft and cannot be cleaned and used, resulting in a large waste of resources. At the same time, when the material accumulates to a certain amount, the smoothness of the conveying will be greatly reduced, blockage will occur, affecting the normal operation of the device and reducing the working efficiency of the equipment.
