Example Embodiment

[0018] Attached below Figure 1-4 An embodiment of the invention is described.

[0019] A hot press forming mold for glass fiber reinforced unsaturated polyester plastic products with a complex structure includes an upper mold plate 11, an upper mold 12, a lower mold 15, a mold foot 18 and a lower mold plate 26. The upper mold 12 is fixed under the upper mold plate 11, the lower mold 15 is fixed on the upper end of the mold foot 18, the lower end of the mold foot 18 is fixed on the lower mold plate 26, and an integral core is provided between the upper mold 12 and the lower mold 15 21. The upper mold 12 and the lower mold 15 are closed together with the integral core 21 to form the molding cavity 20 of the product 23.

[0020] Two oil cylinders 16 are symmetrically arranged on both sides of the lower mold 15, an ejection back plate 27 is provided above the lower mold plate 26, a top plate 19 is provided on the ejection back plate 27, and a rectangular hole 28 is formed on the top ...

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,...
