Mold closing mechanism, at an injection molding machine, has a liquid oil lubrication system to lubricate the toggle lever joints in one cycle and the spindle drive components in a second cycle

摘要

The mold closing mechanism (1), for an injection molding machine, has a lubrication system (26) for the lubrication of the movement joints (10,10') of the toggle lever assembly (6). The lubricant is liquid, and preferably a lubricating oil. The toggle lever joints are lubricated in an initial lubricating cycle, with a second cycle to lubricate the spindle drive (12) with a spindle (14) and spindle nut (16). A multi-path valve (36) is in the lubricant flow path (32) from the pump (30).
