Two-plate type injection molding machine direct and fast mold locking mechanism oil way system for spring molds

Abstract

The invention relates to a two-plate type injection molding machine direct and fast mold locking mechanism oil way system for spring molds. The two-plate type injection molding machine direct and fastmold locking mechanism oil way system comprises a direct and fast mold locking oil cylinder, a first cartridge valve, a high-pressure auxiliary valve and a variable displacement piston pump set. An oil inlet of the direct and fast mold locking oil cylinder is connected with a port A of the first carriage valve and a port A of a second cartridge valve through pipelines. An oil discharge port of the direct and fast mold locking oil cylinder is connected with a port A of a fifth cartridge valve and an outlet of the variable displacement piston pump set through pipelines correspondingly. An inletof the variable displacement piston pump set communicates with an oil tank. A port B of the fifth cartridge valve is connected with a port A of a third cartridge valve and a port A of a fourth cartridge valve through pipelines. A port B of the second cartridge valve and a port B of the third cartridge valve are connected with an outlet of a servo power motor set through centralized pipelines. Theservo power motor set is composed of a first motor, a second motor and a third motor. The two-plate type injection molding machine direct and fast mold locking mechanism oil way system has the characteristics that the machine performance and quality are improved and the service life of machines and the molds is prolonged.

Description

technical field [0001] The invention relates to the technical field of hydraulic control of a two-plate injection molding machine, in particular to an oil circuit system of a direct-fast clamping mechanism of a two-plate injection molding machine for a spring mould. Background technique [0002] With the rapid development of spring mold technology in recent years, more and more spring molds are used, and the traditional two-platen injection molding machine can no longer meet the actual production requirements. This is because the moment the spring mold is released after the high-pressure release of the two-platen injection molding machine, due to the spring force, the mold will bounce off and push the middle plate to move backward, resulting in the contact between the opening and closing device and the tooth surface of the Corinthian column. , The spring force acts on the opening and closing device. At the moment of opening the gate, the opening and closing device contacts a...

[0002] With the rapid development of spring mold technology in recent years, more and more spring molds are used, and the traditional two-platen injection molding machine can no longer meet the actual production requirements.

This is because the moment the spring mold is released after the high-pressure release of the two-platen injection molding machine, due to the spring force, the mold will bounce off and push the middle plate to move backward, resulting in the contact between the opening and closing device and the tooth surface of the Corinthian column. , the spring force acts on the opening and closing device. At the moment of opening, the opening and closing device contacts and rubs against the tooth surface of the Corinthian column and produces a certain impact sound, which has a great impact on the quality of the injection molding machine.
