Example Embodiment

[0014] In the following, taking forming a motorcycle mudguard as an example, the forming process of the composite material profiled product of the present invention is introduced.

[0015] 1. Mold design. Mold design mainly includes outer mold design and inner mold design. The outer mold is made of metal composite materials that are easy to conduct heat, strong rigidity, high hardness, and fine materials, such as synthetic aluminum, synthetic steel, etc., and are processed by CNC machine tools according to the size of the formed fender and the requirements of the vacuum system. The inner mold is made of materials that are resistant to high temperatures and have superior elasticity after curing, such as silicone, rubber or synthetic rubber. The inner mold is an elastomer product, which needs to be heated and vulcanized to form the inner mold. The mold core is made of non-ferrous metals that are easy to conduct heat and light in material, such as aluminum, and are processed by CNC m...

Abstract

The invention relates to a molding technology of a composite material special-shaped product. The molding technology of the composite material special-shaped product comprises the following steps: 1. die preparation: adopting a metal synthesis material to process an outer die according to the shape requirements of a molded product and the requirements of a vacuum system; heating, vulcanizing and molding a die core to form an inner die as an elastomer product; 2. preparation: blanking fibers, presoaking the fibers and proportioning epoxide resin; 3. product structure arrangement: selecting macromolecular composite materials of different types according to the molded product; setting the epoxide resin content and the fiber content according to the test requirements of the product, preparing early-stage composite materials and laying the prepared composite materials by layers according to the design to reach corresponding thickness; 4. molding: setting a series of molding conditions, such as temperature, time, pressure, negative pressure, oil pressure, and the like according to die amount needed by the product, laying the inner die in the corresponding outer die and heating and inflating the inner die; and 5. separation: guiding high-pressure cold air into a die cooling system and cooling and molding the product to naturally separate the product from the die. The technological method has high efficiency and low cost.

Description

technical field [0001] The invention relates to a molding process of composite material special-shaped products. Background technique [0002] At present, the application of composite materials has been very extensive, and there are many industries and fields involved. Industry and civilian use are more optimistic about the cheapness, easy molding, simple operation and durability of composite materials. And many high-tech industries are optimistic about its high-end uses, such as: aerospace, medical, automotive, high-end sports equipment, sporting goods, etc. [0003] However, at present, the molding of composite material products is mostly manual molding. This molding method undoubtedly requires high labor costs, low efficiency, and a large waste of materials. However, if the mechanized molding process is adopted, the molds for special-shaped products are more complicated. Contents of the invention [0004] The object of the present invention is to provide a low-cost, h...
