Abstract
An injection molding apparatus includes a screw housed in a heating cylinder, a rotator for rotating the screw, a linear mover for moving the screw linearly, a motor for driving the rotator, a driver for driving the linear mover, and a base member for supporting the screw, the rotator, the linear mover, the motor and the driver. The screw, the linear mover and the rotator are supported by the base member along a vertical line against the ground. In the injection molding apparatus is a nozzle touch mechanism which includes a support member mounted on the base member, and a member for mounting a die member mounted on the support member to support the die member. The die member is mounted by the member for mounting the die member so that a molding material entrance port of the die member engages an injection port of the heating cylinder. The nozzle touch mechanism further includes a spring member provided between the member for mounting a die member and the support member so as to exert a nozzle touch force on the heating cylinder and the die member.
