METHOD AND DEVICE FOR INJECTION MOLDING

摘要

A method for injection molding comprises the following steps: a step of preparing a first mold, a second mold, and a third mold, a step of sandwiching a separator single body by the first mold and the second mold, a step of injecting silicone rubber into a front-side cavity through a gate to form a front-side formed layer, a step of replacing the second mold with the third mold while the front-side formed layer is soft, and a step of penetrating the front-side formed layer by injection pressure of the silicone rubber injected through the gate, filling the silicone rubber into a back-side cavity through a penetration hole, and forming a back-side formed layer.
