Sound insulated injection molding machine

摘要

A system having a cooled power unit assembly, preferably an injection molding machine (110), is disclosed. The system comprises a primary machine; an electric motor (112) for providing power to at least one mechanism of the primary machine, preferably the injection molding machine (110). The electric motor (112) exhibits an operating temperature and an operating noise level. A cooling liquid (120) is provided for cooling the electric motor (112) and regulating the operating temperature. Also, a cabinet for containing the cooling liquid (120) adjacent the electric motor (112) is provided. The cabinet has means for placing the cooling liquid in a configuration for insulating a surrounding environment from any of the operating noise level which measures above a prescribed level. <IMAGE>
