PURPOSE:To improve the operating efficiency and to simplify the maintenance control by coupling adjacent culls with auxiliary runners. CONSTITUTION:Opposed cavities 21 communicate with culls 23 through main runners 22. The adjacent culls 23 are integrally communicated through auxiliary runners 24. Since the culls 23 are integrally communicated through the runners 24 in this manner, resin can be press-fitted with substantially uniform pressure in all cavities 21 irrespective of the mounting positions of plungers. Thus, molded products of high quality can be readily obtained. |
