[0002] Carbon fiber refers to some materials made of carbon fiber weaving or multi-layer composite. Because it is light and hard, it has a wide range of uses. PPS+CF is used to improve strength during injection molding. PPS+CF is a common material for carbon fiber injection molding. PPS+CF means carbon fiber reinforced polyphenylene sulfide, which is a kind of thermoplastic carbon fiber.

[0003] An existing patent (publication number: CN 213321431 U) discloses an automotive carbon fiber body integral molding mold, which moves the upper mold base downward so that the blocking column can block the second feed hole, so that the cavity can form a sealed space, reduce burrs at the connection between the feed hole and the cavity, facilitate subsequent modification work, save production costs and improve production efficiency.

When subsequent production is carried out after the removal is completed, the movable plate 150 descends and drives the piston rod 330 and the piston 320 to descend through the pressing block 340, so that the piston 320 squeezes the gas inside the piston cylinder 310, and the gas is ejected from the gas nozzle 360 ​​through the connecting pipe 350, so as to clean the debris inside the mold cavity of the male mold 170, effectively preventing the debris from being inside the cavity, causing defects in the appearance of the subsequently produced products, resulting in reduced product quality.
