发明名称 INJECTION MOLDING DIE AND INJECTION MOLDING METHOD
摘要 <P>PROBLEM TO BE SOLVED: To provide an injection molding die which has a simple constitution and from one of which a plurality of resin-molded articles different in shape or volume can be obtained with high precision by one injection, and to provide an injection molding method. Ž<P>SOLUTION: A resin fluidity adjustment part 56 is arranged one end of which is abutted on a flow passage of a runner 51 communicated with a molded article transfer part 72 having a cylindrical vessel-like shape of larger volume. The resin fluidity adjustment part 56 has the thermal conductivity different from those of surrounding die members and is covered with an insulating member 57. The other end of the resin fluidity adjustment part 56 is connected to a heat source. A porous part 58 is arranged to be connected successively to the edge of the runner 51 and consists of a porous material having a plurality of voids extending from one end thereof to the other end. Three overflow parts 74 are arranged to be communicated with another molded article transfer part 73 having a triangular vessel-like shape of smaller volume. Another porous part 75 is arranged to be connected successively to each of three overflow parts 74. The fluidity of a resin in a resin flow route part is adjusted by the resin fluidity adjustment part 56 and the porous parts 58 and 75. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
