Abstract

PURPOSE:To enable to manufacture the compact type injection molding machine by a method wherein a part of injection molding machine, say a tiebar is utilized as a part of magnetic circuit. CONSTITUTION:The tieber made of magnetic material may be utilized as a part of magnetic circuit. When an electromagnet is excited, a magnetic circuit is formed to make intermediate pole shoe needless enabling to manufacture the compact type injection molding machine.
