Tool closure system for an injection molding machine has a linear motor primary part moving along a tie bar acting as a secondary motor part

摘要

Linear movement of a moving platen(AP,SP) towards the fixed platen(TP) to close the tool is effected by a primary part(L1,L2) of a linear motor on at least one of the machine tie bars(H1,H2). The secondary part of the motor is formed by the tie bars themselves.
