Title:
MOLD ARTICLE PROJECTING DEVICE FOR INJECTION MOLDING MACHINE
Document Type and Number:
Japanese Patent JP3248097
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To drastically reduce the cost, and realize the miniaturization of the whole body, and at the same time, improve the degree of freedom in designing and the developability by simplifying the constitutions of the driving system and the control system.
SOLUTION: A plurality of ejector pins 3a... which face to the cavity C of a die 2, and a moving mechanism part 4 which moves respective ejector pins 3a... under different projecting conditions, are provided, and at the same time, one driving part 5 which outputs a driving force in the advancing/ retracting direction especially for the moving mechanism 4, and a movement converting mechanism part 6 which movement-converts the driving force which is output from the driving part 5 and transmits it to the plurality of the ejector pins 3a..., and individually moves respective ejector pins 3a... under different projecting conditions, are provided for the constitution.
