A nozzle-contacting device of an injection molding machine includes an injection module and a mold-holding structure both set on a lathe bed. The injection module sets a nozzle at a front end thereof and a nozzle-adjusting device, which is fixed and locked on the lathe bed, at a back end thereof. The mold-holding structure includes a mold-clamping structure and an adjusting plate, wherein the mold-holding structure sets plural tie rods. A mold is fixed and locked on the adjusting plate which is sleeved on plural tie rods, and one or more driver set on a front end of a dead plate penetrates the dead plate to connect to the adjusting plate. Furthermore, the dead plate has a perforation set on a center thereof corresponding to a position of the nozzle of the injection module.

Nozzle-contacting device of injection molding machine

A device for clamping electromagnetically molds of the injection molding machine comprises a stand on which a fixed board and a guiding mechanism are mounted. A movable board is slidably mounted on the guiding mechanism to slide back and forth in relation to the fixed board. The fixed board is provided with a male mold mounted thereon. The movable board is provided with a female mold mounted thereon. The sliding motion of the movable board toward the fixed board brings about the mold opening action, the mold closing action, and the mold locking action. The movable board and the fixed board are provided with a magnetic force generating mechanism for effecting attraction or repulsion between the movable board and the fixed board. The attraction serves to effect the mold closing action and the mold locking action. The repulsion serves to effect the mold opening action.

Method and device for clamping electromagnetically molds of injection molding machine

A speed-up mechanism for an injection molding machine has a front fixed plate having a through hole at the center; a rear fixed plate arranged parallel with the front fixed plate, and the rear fixed plate having at least one through hole; at least two guide bars parallel to each other arranged between the front fixed plate and the rear fixed plate in an equal distance; a movable plate slidably arranged on the guide bars between the front fixed plate and the rear fixed plate, and capable of moving toward and away; a rotary power source fixed on one side of the movable plate for providing rotary power, the rotatry power source comprising a transmission device; a fixed nut mounted on the rear fixed plate; at least one ball screw having two threads in opposite directions at two ends, the front end is engaged with the transmission device for generating a radial rotation, the rear end is engage with the fixed nut and through the rear fixed plate to generate an axial movement for the ball screw during the rotation; and at least one movable nut engaged with the front end of the ball screw to move along the ball screw during the rotation of the ball screw, the outside of the movable nut is connected to the movable plate to drive the movable plate in the axial direction during the rotation of the ball screw.

Speed-up mechanism for an injection molding machine

An electromagnetic driving device for a mold clamping system is disclosed, which has a stationary plate fixedly mounted on a lathe bed; a mold guiding mechanism mounted parallel on the lathe bed; a movable plate slidably arranged on the mold guiding mechanism, facing the stationary plate, for generating a relative slide to the stationary plate; and a movable plate driving mechanism for driving the movable plate on the mold guiding mechanism. The electromagnetic driving device utilizes magnetic force to drive the linkage, movable plate etc. to perform open-mold movement, close-mold movement, and mold-locking movement.
