IPC: B29C43/36
Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To provide a compression molding die which is of a plural cavity type and enables and insertion pin used or molding a through hole region to be simply drawn from a molded product and thereby is made to function with very high productivity. SOLUTION: This compression molding die for molding rubber has at least two through hole region connected to a rubber molded product base block 22 of an almost flat platelike shape, the first through hole region being positioned almost level with the rubber molded product base block 22 and the other second through hole region being obliquely angled 15-45 deg. with the rubber molded product base block 22. In addition, this molding die is substantially of a two-split part type consisting of a top force 2 and a bottom force 3. A first insertion pin 7 for forming the first through hole region is moved almost horizontally by a cam mechanism actuated by mounting/demounting a movement guide core (tapered boss).  A second insertion pin 8 for molding the second through hole region makes a substantially rotating motion by opening the top force 2 and the bottom force 3 based on a hinge part formed on the lateral faces of the top force 2 and the bottom force 3. Thus this rotating motion structurally forces the second insertion pin 8 out of the molded product.
