Abstract
PURPOSE: To obtain the molding device which centrifugally molds a tube not cured on a die for plastic processing, integrally extract it form a rotary die and can plastically process it by mounting an attachable intermediate die on the inner circumferential surface of the rotary die and an attachable rubber die on an inner circumferential surface of the intermediate die.
CONSTITUTION: A material is supplied onto a molding inner surface of the rubber die 16 through a central through-hole of either of end surface jigs 21A, 21B turning the rotary die 2 around a rotary axis 1, and a tube 27 as a product is molded centrifugally as shown in a section lower than the rotary axis 1. Even if the molding inner surface of the rubber die 16 is deformed previously due to errors on the production and the eccentricity and the like of the rotary die 2, the intermediate die 4, etc. when the tube is molded centrifugally in this manner, the deformation is changed into a true circle according to the functioning of a liquid. One part of the material often drops into the end surface jigs 21A, 21B when supplying the material, but the dropped material is discharged automatically by means of tapered surfaces 25A, 25B tapered to the outside. The rotary die 2 is divided, and the product 27 is extracted together with the intermediate die 4 and the rubber die 16.
