摘要 |
An injection mold and an injection molding apparatus having a movable mold and a fixed mold. Each of the movable/fixed molds has bases, and a runner, a gate and a cavity are formed. The gate is composed of recesses made in mutually opposite end surfaces of sleeve-like heat insulators provided for the bases. Thereby, the gate is heat-insulated, and resin in the gate is prevented from cooling down during a pressure retention step. Thus, the resin keeps fluidity longer.
