Abstract

The invention discloses a method for adjusting the mould clamping force. The method comprises the following steps that A, a programmable logic controller (PLC) receives the target mould clamping force F input by a user; B, according to the target mould clamping force F, the PLC calculates the target rotating tooth number N of a corresponding gear; C, the PLC outputs a signal to control a hydraulic motor to rotate and then drives a gear mechanism on a tie bar to rotate, and a movable mould plate is driven to move; D, the PLC receives the current rotating tooth number N', sent by an electromagnetic induction sensor, of the gear; and E, when N'=N, the PLC controls the hydraulic motor to stop rotating, the process is finished, and otherwise, the step C is returned. Through a system, the mould clamping force of a machine hinging type mould closing mechanism can be automatically adjusted, the cost is effectively reduced, meanwhile, the system adopts all-digital signals, the interference or data distorting phenomenon does not occur, and the mould adjusting efficiency is greatly improved.

Description

technical field [0001] The patent of the present invention relates to the field of mold equipment, specifically a clamping force adjustment system and adjustment method. Background technique [0002] When the die-casting machine or injection molding machine is working, the extrusion molding of the mold can only be realized after the movable template and the fixed template are molded and locked. When the mold is formed, the extruded mold will generate a huge force to separate the fixed plate and the movable plate, so the equipment should provide a huge clamping force in a short time when the mold is extruded. In order to ensure the quality of the mold, it is necessary to precisely control the clamping force. [0003] In the prior art, the method of adjusting the clamping force is as follows: Use the stretch sensor to measure the stretch of the Gelin pillar, cooperate with the conversion board to convert the stretch into a 0-10v analog signal, and use the computer analog acqu...
