Manufacturing process of mold for manufacturing carbon fiber box

Abstract

The invention relates to a manufacturing process of a mold for manufacturing a carbon fiber box. In the process, a male mold is used. The manufacturing process comprises the following steps: step 1, spraying a gel coat on the outer surface of the male mold and curing to form a gel coat layer; step 2, coating the gel coat layer with surface felt to form a surface felt layer; step 3, gluing at least three layers of shortly-chopped felt on the surface felt layer to form a shortly-chopped felt layer, and curing the surface felt layer, resin and the shortly-chopped felt layer to form a glass fiber reinforced plastic layer; step 4, sequentially laying the shortly-chopped felt layer, a multi-axial cloth layer and a bordering cloth layer on the glass fiber reinforced plastic layer; step 5, filling in vacuum, namely sequentially laying de-molding cloth, a double-layered flow guide net, a flow guide belt, a flow guide pipe and a double-layered vacuum bag on the layer in the step 4, and after keeping pressure, filling to primarily form a female mold shell plate; step 6, gluing a steel frame and a steel plate; and step 7, after sticking the steel frame and the female mold shell plate for at least 48 hours, taking out the male mold from the female mold shell plate so as to manufacture the mold. The manufacturing process provided by the invention has the characteristics that the high-strength performance of the mold is guaranteed, the durability of the mold is improved, the service life of the mold is prolonged and the like.

Description

technical field

[0001] The invention relates to the technical field of mechanical manufacturing technology, in particular to a manufacturing technology of a mold for manufacturing carbon fiber boxes. Background technique

[0002] Carbon fiber box is a kind of carbon fiber product. In the military field, carbon fiber boxes are widely used, which meet the requirements of troops for easy portability, diversified built-in items, and violent loading and unloading. The current method of manufacturing carbon fiber boxes is to press molds, and the existing molds have some defects: 1. High manufacturing and maintenance costs; 2. The strength of the manufactured products cannot be guaranteed; 3. The quality of the manufactured products is relatively heavy. Contents of the invention

[0003] Aiming at the above technical problems, the present invention provides a manufacturing process of molds for manufacturing carbon fiber boxes that can not only ensure the high strength performanc...
