A water injection method demoulding device and demoulding method for the production of glass fiber reinforced plastic products

Abstract

The invention provides a water injection method demoulding device and method for the production of fiberglass products. The water injection method demoulding device comprises a supporting frame, a vibration mechanism, a mould and an auxiliary mechanism. The vibration mechanism is arranged at the upper end of the supporting frame, the mould is arranged in the vibration mechanism, and the auxiliarymechanism is arranged at the top end of the supporting frame. The fiberglass products to be demoulded are arranged in the mould. According to the water injection method demoulding device and method for the production of the fiberglass products, the problems that the mould is not easy to be peeled off due to the fact that injected water is not easy to infiltrate into the mould and prone to sprinkling, the water is expanded to the whole mould under vibration by manually extending forward and knocking along a water injection port, but the manually knocking is prone to damaging the mould, the inner wall of the mould is caused to fall off or the mould is caused to crack, and the mould is caused to be unable to be used twice are solved; and the function of conveniently separating the mould fromthe products can be realized.

Description

technical field [0001] The invention relates to the technical field of production and processing of glass fiber reinforced plastic products, in particular to a water injection demoulding device and a demoulding method for the production of glass fiber reinforced plastic products. Background technique [0002] Some FRP products are completed with the help of molds in the production and processing process. It is necessary to pour the liquid FRP materials into the pre-prepared molds. After the products are condensed and formed, the products are removed from the mold. Strike method, air pressure method, water injection method and wedge method, but the percussion method is mainly easy to damage the mold; the air pressure method needs to punch a 5mm hole at the bottom of the mold, but it is easy to be poured by resin when injecting liquid FRP material, making it It cannot be used; the entry point of the wedge method should be selected at the common stress point of the product and ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above problems, the present invention provides a water injection demoulding device and a demoulding method for the production of FRP products, which can solve the problem that the usually injected clean water is not easy to penetrate into the mold, and it is easy to spill, so that the mold is not easy to be peeled off. The water injection port is extended forward and knocked so that the water expands to the entire mold under vibration, but manual knocking is easy to damage the mold, causing the inner wall of the mold to fall off or cause cracks in the mold, causing the mold to be unable to be used again; it can realize the convenience of mold and The function of product separation; it has the advantages of not easy to spill when the water flows into the mold, knocking the mold will not damage the mold and the product, and better expand the water to the entire mold, improving the demoulding efficiency, etc.
