When the parallelism of the used mold is not matched with or poorly matched with the parallelism of the injection molding machine, the detection part 1 detects the change of the strain value of the guide post 2, the control system judges and gives instructions according to the detection data of the detection part 1, so as to control one or more driving components 9 to do micro-motion and drive the corresponding transmission components to do motion, change the verticality of the movable template relative to the axis of the guide post 2, the parallelism between the plane attached to the movable mold on the movable mold plate of the injection molding machine and the plane attached to the fixed mold on the fixed mold plate is changed, the technical effect of enabling the parallelism of the injection molding machine and the parallelism of the mold is achieved, the size of mold locking force required by qualified products is reduced, the energy consumption of the injection molding machine is reduced, the service life of the injection molding machine is prolonged, and the problems that the parallelism of the mold is not matched with or is poor in matching in the prior art are solved.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
