PURPOSE:To reduce the temp. difference generated between the resin injected in a cavity in the vicinity of a gate port and the resin injected in the cavity at a part separated from the gate part. CONSTITUTION:Four gate ports 6A, 6B, 6C, 6D injecting a resin into a cavity 7 from a runner 5 are provided. Since the resin can be almost simultaneously injected into the cavity 7 from the gate ports 6A-6D. The temp. difference between the resin in the vicinity of the gate ports 6A-6D and the resin at parts separated from the gate ports 6A-6D can be reduced and the accuracy of the solidified resin can be enhanced. |
