A kind of intelligent mold opening and closing control method and control system of die casting machine

Abstract

The invention discloses an intelligent die opening and closing control method for a die-casting machine. The method comprises the following steps that displacement information sent by a displacement sensor is obtained by a programmable controller, and displacement information of a moving template is worked out; and according to the displacement information of the moving template, the intensity of die opening and closing of the moving template is controlled by the programmable controller. The invention further discloses an intelligent die opening and closing control system for the die-casting machine. The system comprises the moving template, the programmable controller and the displacement sensor; and the programmable controller is connected with the displacement sensor and used for receiving the displacement information sent by the displacement sensor, the programmable controller is connected with the moving template through a transmission mechanism and used for working out the displacement information of the moving template according to the displacement information sent by the displacement sensor, and the intensity of die opening and closing of the moving template is controlled according to the displacement information of the moving template. According to the intelligent die opening and closing control method and system for the die-casting machine, die opening and closing action is stable and pliable, the impact strength and the vibration amplitude of the moving template are reduced, the intensity of die opening and closing of the movable template can be controlled by the programmable controller, and die opening and closing efficiency is guaranteed.

Description

technical field [0001] The invention relates to the technical field of die-casting machine automatic control, in particular to an intelligent mold opening and closing control method and control system for a die-casting machine. Background technique [0002] The die-casting machine is a device that injects molten metal directly into the mold, and makes the molten metal cool and form in the high-pressure environment in the mold. During the production process, the clamping force is required to be large enough to prevent the mold from expanding. When opening the mold, it is necessary to overcome a huge clamping force to realize the mold opening. [0003] In the prior art, during the mold opening and closing movement of the die-casting machine, the start and stop of the movement of the movable platen are abrupt, which is reflected in the large shock and vibration in the movement. Although this kind of equipment can open and close the mold quickly, the instantaneous impact of th...

AI Technical Summary

Problems solved by technology

Although this kind of equipment can open and close the mold quickly, the impact of the moving platen will seriously affect the stability and service life of the equipment, and even pose a safety hazard.
