Abstract

The invention provides a manufacturing method for a glass fiber reinforced plastic pressing mould. Unsaturated polyester resin and glass fibers are used as main materials for the pressing mould, and steel is used as a framework to fix the pressing mould. The manufacturing method comprises the following steps: fabricating a wood mould or a plaster mould according to product design requirements; brushing a gel coating on the waxed mould; pasting alkali-free surfacing mat, with an impregnating compound being an S-904 resin mixture; pasting alkali-free chopped strands of the glass fibers; pasting medium-alkali glass fiber plaid; pasting a plurality of layers of medium-alkali glass fiber plaid, with an impregnating compound being an S-685 resin mixture; pasting a plurality of layers of medium-alkali glass fiber plaid again, with an impregnating compound being an S-191 resin mixture, so as to finish fabrication of the glass fiber reinforced plastic pressing mould. According to needs of the mould, the framework for the mould is welded, flat steel and support are installed, and the glass fiber reinforced plastic pressing mould is fixed on the framework for the mould by using countersink bolts. According to the invention, manufacturing cost for the glass fiber reinforced plastic pressing mould is low, readjusting and remodification of the mould can be carried out, and products capable of satisfying current performance requirements for interior decorative parts for automobiles can be produced.

Description

technical field

[0001] The invention relates to the manufacture of a pressing mold, in particular to a method for manufacturing a glass fiber reinforced plastic pressing mold. Background technique

[0002] Now all the pressing molds are made by traditional pressing molds. The materials are all steel. There are high cost of mold making and long production cycle. It is not easy to adjust or modify the mold again. At the same time, the pressing produced by steel mold Products, pressed products lack elasticity on the surface. The original traditional steel mold cannot be used to produce products that meet the performance requirements of the current automotive interior parts (mainly the processing of hemp fiberboard and PVC fabric products). Nowadays, people have higher and higher requirements for the product performance of interior parts, and the products must be environmentally friendly, and have high flame retardancy, sound insulation, heat insulation performance and good sur...
