MOLD AND MOLDING METHOD OF RESIN MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a mold and a molding method of a resin molding which facilitate the positioning of a vent nozzle to a mold body. SOLUTION: An engaging part 35 is prepared at an overhanging part 30 of the vent nozzle 7; a clearance 40 for inserting the overhang part 30 is prepared at a mold body 2; a hole 21 for the vent nozzle through which the overhang part 30 can pass when the overhang part is in a given rotation posture is prepared between the clearance 40 and the outside; an engaging target 41 engaged with the engaging part 35 is prepared in the clearance 40; a slope 42 is prepared at one or both of the engaging part 35 and the engaging target 41; and the vent nozzle 7 can rotate only at a given rotation angle in a state that it is inserted to a vent nozzle inserting hole 6, that the overhang part 30 is in the clearance 40 and that the engaging part 35 and the engaging target 41 are in contact with each other. The vent nozzle 7 can be driven in the axial direction of the vent nozzle insertion hole 6 by a drive force which is generated by the slope 42 when the vent nozzle 7 is rotated in that state.
