Double-valve parallel mode adjusting and locking system for two-plate injection molding machine

Abstract

The invention discloses a double-valve parallel mode adjusting and locking system for a two-plate injection molding machine. The system comprises a main oil line module and an oil line control module, wherein the main oil line module comprises a power source, a three-position and four-way directional valve group, a pilot operated check valve and an actuating mechanism; the oil line controlling module comprises a two-position four-way directional control valve group; the outlet of the power source is connected with the inlet of the three-position four-way control valve group; the outlet of thethree-position four-way directional control group is connected with the inlet of the pilot operated check valve; and the outlet of the pilot operated check valve is connected with the actuating mechanism. In the invention, the power source is controlled accurately, so that the energy conservation of the whole two-plate injection molding machine is realized; and the two-plate injection molding machine controls the rotating speed of a servo motor to enable the output flow of a quantified hydraulic pump to be matched with the required flow of the two-plate injection molding machine synchronouslyin real time. The system disclosed by the invention can be used for greatly improving the rapidness and accuracy of mode adjusting action of the double-plate injection molding machine and simultaneously enabling the mode locking action to be more reliable and simpler.

Description

technical field [0001] The invention belongs to the technical field of plastic machinery, and in particular relates to a mold adjusting and locking system of a double-valve parallel-connected two-platen injection molding machine. Background technique [0002] Injection molding machine is one of the most important types of plastic machinery, responsible for the processing of more than 30% of general-purpose plastics and more than 90% of engineering plastics. With the development of the injection molded parts market, there are more and more types of injection molded parts, especially the rapid development of the large injection molded parts market, which puts forward new requirements for the ability of injection molding machines to process large injection molded parts. At present, the toggle injection molding machine still occupies a dominant position in the domestic injection molding machine market, but the toggle injection molding machine has many outstanding shortcomings su...

AI Technical Summary

Problems solved by technology

At present, some companies in China have successfully developed two-platen injection molding machines, but there are shortcomings such as long mold adjustment time, complicated mold locking process, and inconvenient control in the successfully developed mold adjustment and clamping mechanisms. Therefore, it is necessary to develop a simpler and more convenient one. Adjustment and locking system
