Title:
PLASTIC FEEDING STRUCTURE OF CARBON FIBER BOARD
Document Type and Number:
WIPO Patent Application WO/2021/218135
Kind Code:
A1
Abstract:
A plastic feeding structure of a carbon fiber board, comprising an inclined pin (1) and a mold core (2), wherein the mold core (2) is provided with a plurality of hot nozzle heads (3). When the oblique pin (1) abuts against the mold core (2), a flow channel (4) and a discharge port (5) are formed between the oblique pin (1) and the mold core (2). The flow channel (4) comprises a first cavity (401) and a second cavity (402) which are in communication with each other, and the second cavity (402) is narrowed relative to the first cavity (401). The hot nozzle head (3) is in communication with the first cavity (401), the discharge port (5) is in communication with the second cavity (402), and the discharge port (5) is elongated. According to the plastic feeding structure of the carbon fiber board, plastic first passes through the first cavity during feeding, then through the second cavity, and finally flows out from the discharge port, which reduces the impact of the plastic on the carbon fiber board and prevents a punching impression from being left on the carbon fiber board.
