Hot pressing forming die for glass fiber reinforcement unsaturated polyester plastic products with complex structure

Abstract

The invention provides a hot pressing forming die for glass fiber reinforcement unsaturated polyester plastic products with a complex structure. According to the invention, an integral core is arranged between an upper die and a lower die of the forming die, and after die locking of the upper die and the lower die, a forming die cavity of a product is formed by the upper die, the lower die and the integral core together; two oil cylinders are symmetrically arranged at two sides of the lower die, an ejector back plate is arranged above a lower die plate, a push plate is arranged on the ejector back plate, piston ends of the oil cylinders are fixedly connected with the lower die plate, cylinder body ends are fixedly connected with the ejector back plate, the ejector back plate pushes the integral core and pushes a push rod through the push plate, the push rod and the integral core synchronically move upwards, and at the same time, the integral core synchronically move outwards, thereby enabling ejection of a formed product and sideward opening of the integral core to be realized synchronically and demolding problems of formed products with a complex structure to be overcome. The forming die is especially applicable to forming of products with a complex structure and nonuniform wall thickness.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a complex structure glass fiber reinforced unsaturated polyester plastic products thermocompression forming mold. Background technique [0002] The closest existing technology to the present invention is the patent application for "SMC thermoforming mold (CN200810217429.0)" disclosed on June 16, 2010, including an upper mold, a lower mold, and the clamping of the upper mold and the lower mold The mold cavity formed after that, the mold cavity is provided with a molding surface of the molded product, and the upper mold or the lower mold is provided with a heating system that makes the molding surface evenly heated, and the heating system is evenly distributed on the upper mold, The molding part of the lower mold. The mold is easy to shape products with a simple structure, but cannot shape products with a complex structure only through the upper mold and the lower mold,...

Problems solved by technology

[0003] The technical problem solved by the present invention is to provide a hot-press molding mold for glass fiber reinforced unsaturated polyester plastic products with a complex structure. By setting an integral core between the upper mold and the lower mold, the Together with the integral core, the molding cavity of the product is formed, which not only solves the molding problem of the product with complex structure, but also solves the problem of demoulding after the product with complex structure is formed.
