NOZZLE TOUCH MECHANISM OF INJECTION MOLDING MACHINE

摘要

A plurality of connecting rods are attached to an injection device located opposite a stationary platen on a base structure of an injection molding machine. The stationary platen is provided with a magnetism generating unit formed of a permanent magnet, and the connecting rods are provided with a magnetic body. As the magnetism generating unit and the magnetic body are attracted to each other by magnetism, a nozzle of an injection unit is brought into contact with a mold. By this structure, the stationary platen can be prevented from inclining during nozzle touch operation.
