Title:
MOLD
Document Type and Number:
Japanese Patent JPH0631779
Kind Code:
A
Abstract:

PURPOSE: To mold an article without using an insert even if it has a projected part by a method wherein an entrainment part, such as a door trim for a motorcar, is molded using an inclined core and a push-up block, a molded article is removed from the inclined core by a first removing means, and the entrainment part is removed from the push-up block by moving the molded article in a predetermined direction by a second removing means.

CONSTITUTION: An inclined core 39 is mounted on a movable mold 22 by a rod 38 so as to abut on or separate from the mold 22. A push-up block 44 connected to a rod 45 slidably inserted through the movable mold 22 is provided with a stripping slide 46 connected to an actuator 50 of a hydraulic cylinder 49. After molding, with a mold opening operation, an ejection pin ejects a door trim 101, and the rod 38 progresses askew to remove the inclined core from an entrainment part 101a of the door trim 101. With the further progress of the mold opening operation, the rod 45 moves forward to eject the push-up block 44. Thereafter, the hydraulic cylinder 49 is actuated to move the stripping slide 46 so as to pull the door trim 101. In this manner, the entrainment part 101a is removed from the push-up block 44.
