Abstract

A differential injection module used on an injection molding machine comprises a mold body. The mold body is provided with an oil inlet, an oil outlet, an oil entering opening, an oil backflow opening, an injection control valve, a one-way valve and a flow control valve, wherein the oil inlet and the oil outlet communicate with an oil tank, the oil entering opening communicates with a push cavity of an injection oil cylinder, and the oil backflow opening communicates with a loosening cavity of the injection oil cylinder. The injection control valve, the one-way valve and the flow control valve are connected with a control circuit through wires correspondingly. The oil inlet, the oil outlet, the oil entering opening and the oil backflow opening communicate with the injection control valve through pipelines correspondingly. The one-way valve is arranged on the pipeline enabling the oil backflow opening to communicate with the injection control valve. The flow control valve is arranged on the pipeline enabling the oil inlet to communicate with the injection control valve. A valve element capable of moving left and right is arranged in the injection control valve. After the valve element moves leftwards / rightwards, the oil inlet communicates with the oil entering opening; and after the valve element moves rightwards / leftwards, the oil inlet communicates with the oil backflow opening. The differential injection module has the beneficial effects that the oil way flow is adjusted conveniently, and the injection oil cylinder is stable in pushing and high in push efficiency.

Description

technical field [0001] The invention relates to the technical field of manufacturing an injection molding machine, in particular to a differential injection module used on an injection molding machine. Background technique [0002] An existing Chinese utility model patent with the patent number CN201120546009.4 titled "A Double-rod Double-Differential Injection Mechanism for a Two-Platen Injection Molding Machine" discloses a double-rod double-differential injection mechanism for a two-platen injection molding machine, which involves injection molding machine. The utility model solves the problem of restricting the enlargement of the injection mechanism of the injection molding machine. The utility model consists of a double-bar injection device and a double-differential injection device. The double-bar injection device includes: an injection mechanism bed, an injection mechanism guide rail base, a double differential injection device, and a storage device; The injection d...
