Abstract
A system having a cooled power unit assembly, preferably an injection molding machine. The system comprises a primary machine; an electric motor for providing power to at least one mechanism of the primary machine, preferably the injection molding machine. The electric motor exhibits an operating temperature and an operating noise level. A cooling liquid is provided for cooling the electric motor and regulating the operating temperature. Also, a cabinet for containing the cooling liquid adjacent the electric motor is provided. The cabinet has a device 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.
Claims26
A hydraulic injection molding machine comprising:
- an injection unit;
- a clamp unit for clamping molds;
- at least one hydraulic pump for driving said injection and clamp units;
- an electric motor means for powering said at least one hydraulic pump, said electric motor means exhibiting an operating temperature and an operating noise level;
- liquid means for cooling said electric motor means and regulating said operating temperature;
- means for containing said liquid means adjacent said electric motor means, said means for containing having means for placing said liquid means in a configuration for insulating a surrounding environment from any of said operating noise level which measures above a prescribed level;
- and
- including a clamp manifold to power the clamp unit and an injection manifold to power the injection unit, wherein the liquid cooled electric motor means is operative to control the clamp manifold and injection manifold, and including a power manifold hydraulically connected to said clamp manifold and injection manifold.
