Title: Molding die
Inventor: KAMIYUU TAKESHI
IPC: B29C33/42
Filed: 1989-11-22
Abstract: PURPOSE:To make it possible to smoothly perform the releasing operation of a molded product by using a structure wherein pressing member, which can move to the lamping and parting direction of a top force and a bottom force, are provided. CONSTITUTION:Since pressing members 27 are so constituted as to allow to move to the lamping and parting direction of forces, when a top force 20 and a bottom force 21 are parted from each other in order to release a molded product 32 from the forces after molding, the top force 20 is earlier parted from the molded product 32 than the pressing members 27, resulting in releasing the stress at the upper part of the molded product 32. Accordingly, the stress applying to the pressing members 27 is relieved, resulting in allowing decentralizing the concentration of stress developed at some part of the pressing members 27 due to the shrinkage of the molded resin 24 occured after molding through the movement of the pressing members 27 for getting out of the molded product 32. Thus, the mold releasing operation of the molded product is performed smoothly and short shot at molding is prevented from occurring and, in addition, molded product, which is excellent in external beauty and has corners with high mechanical strength, can be obtained easily.
