Novel structure of one-way valve of injection mechanism

Abstract

The invention provides a novel structure of a one-way valve of an injection mechanism. The novel structure of the one-way valve of the injection mechanism is characterized by comprising a valve seat,a rodless cavity, a spring, a valve element, a valve hole, a valve body and a stroke oil hole, wherein the valve seat is connected with the valve body to be arranged, the rodless cavity is formed in the valve seat, the valve element is arranged in the cavity, the compression spring is arranged in the valve element, the annular valve hole is arranged outside the valve body, the stroke oil hole is formed in the center of the valve body, and the valve seat and the valve body are connected through a connecting flange to be arranged. The novel structure of the one-way valve of the injection mechanism has the advantages of being simple in structure, small in occupied space, easy to manufacture, low in manufacturing cost, convenient to install and maintain, high in oil path integration level andthe like.

Description

technical field [0001] The invention relates to the technical field of die-casting machine parts, in particular to an injection device of an injection mechanism, and particularly provides a new structure of a one-way valve of an injection mechanism. Background technique [0002] With the advancement of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles and household appliances, and starting from energy saving and saving raw materials, die-casting technology has been applied to many fields. The core of die-casting machines The component is the injection device, and the core component of the injection device is the valve body structure. The valve body structure used in the existing die-casting machine is complex, difficult to manufacture, complicated to install and maintain, short in service life, high in damage rate, and poor in operation stability. Because the damage of the valve body needs to be s...

[0002] With the advancement of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles and household appliances, and starting from energy saving and saving raw materials, die-casting technology has been applied to many fields. The core of die-casting machines The component is the injection device, and the core component of the injection device is the valve body structure. The valve body structure used in the existing die-casting machine is complex, difficult to manufacture, complicated to install and maintain, short in service life, high in damage rate, and poor in operation stability. Because the valve body is damaged, it needs to be shut down for maintenance, which greatly reduces productivity and wastes time and cost
