IPC: B29C47/08
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To eliminate the necessity of fire source such as a gas burner and prevent the roughness of a coated surface caused by air spray by exhausting air out of a slit-shaped air plenum formed between the end of a molding die and the end of an air blow die and cooling the end of the die locally. SOLUTION: An air blow die 13 is disposed concentrically on the outside of a molding die 12, and an air passage 14 is formed between the dies. At that time, the end of the molding die 12 is formed into a sharp bill shape, and the end 12a is protruded slightly more than the air blow die 13. Thus a slit- shaped air plenum 14b is formed between the end of the molding die 12 and the end of the air blow die 13. High pressure air is blown out of the slit-shaped air plenum 14b, and the end 12a of the molding die 12 is cooled locally. Thus the generation of die waste A can be controlled without roughing the surface of a coated layer 2.
