Abstract

The invention relates to a hand lay-up mold pressing vacuum auxiliary forming mold and a forming process. The hand lay-up mold pressing vacuum auxiliary forming mold is used for vacuum auxiliary forming of a product, and the hand lay-up mold pressing vacuum auxiliary forming mold comprises a sealing film, breathable glue absorbing materials, a vacuumizing pipe, an upper mold and a lower mold; a product mold cavity is formed between the upper mold and the lower mold, and a sealing film is arranged in the product mold cavity; a product preformed rough blank is wrapped in the sealing film, and the product preformed rough blank wrapped with the sealing film is located in the product mold cavity; and breathable glue absorbing materials are arranged on the two sides of the sealing film and connected with the vacuumizing pipe, and the vacuumizing pipe is connected with an external vacuumizing device. According to the hand lay-up mold pressing vacuum auxiliary forming mold and the forming process, the cost is low, the efficiency is high, operation is convenient, the appearance aftertreatment time and the mold cleaning time are saved, and the service life of the mold is prolonged.

Description

Technical field [0001] The present invention relates to an auxiliary molding die and a molding process, and more particularly to a hand-molded vacuum auxiliary molding die and a molding process that costs low, high efficiency, convenient operation, saving post-processing time and mold cleaning time. Background technique [0002] Carbon fiber composites are used as a new type of material excellent mechanical properties, and there are more and more widely used in all walks of life. It uses carbon fiber composites to make products, and common molding processes have molds, bag pressures, hand paste, and heat. Pressure tanks, vacuum perfusion, etc., each forming process has its own advantages and disadvantages. [0003] The molding temperature high-quality appearance is easy to appear, need to be dealt with the appearance of the product, it is impossible to use it directly as a finished product; the poor hand technology is poor, the product has a poor performance, low product mechanic...
