Embodiment Construction

[0024] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and contribute to its implementation.

[0025] The invention provides a method for modifying a glass fiber reinforced plastic mold. The glass fiber reinforced plastic mold is used to replace the traditional metal mold as a mold used in the hand lay-up glass fiber reinforced plastic process. The glass fiber reinforced plastic mold is made of glass fiber reinforced epoxy resin composite material, and its main It is composed of a lower template and a punch arranged on the lower template.

[0026] Such as figure 1 As shown, the old FRP mold to be modified needs to be scrapped because it does not meet the production requirements. However, a...

Abstract

The invention discloses a method for modifying a glass fiber reinforced plastic mould, which comprises the steps of: (1) removing the old punch on the lower template; (2) using glass fiber reinforced epoxy resin composite material to make a new punch; (3) installing the new punch on the lower template Set the installation position of the new punch; (4) Bond the new punch to the set position on the lower formwork. The invented FRP mold modification method, by removing the old punch on the lower template and making a new punch on the lower template, can avoid a lot of material, manpower and time costs for remanufacturing the mold, thereby reducing mold development and manufacturing costs , Improve R&D and production efficiency.

Description

technical field [0001] The invention belongs to the technical field of processing technology of glass fiber reinforced plastic moulds, in particular, the invention relates to a modification method of glass fiber reinforced plastic molds. Background technique [0002] Compared with traditional metal molds, FRP material molds are light in weight, low in cost, and have a small thermal expansion coefficient. They can be used as hand lay-up molds for room temperature curing FRP products. Generally, one mold design file corresponds to one pair of molds. When the design file is changed, such as holes and bosses are displaced, the mold needs to be remanufactured, which not only consumes material costs, but also increases labor and time costs. Contents of the invention [0003] The invention provides a method for modifying a glass fiber reinforced plastic mold, with the purpose of reducing the development and manufacturing costs of the mold. [0004] In order to achieve the above...
