Problems solved by technology

[0002] The spool is a valve part that uses its movement to realize the basic functions of direction control, pressure control or flow control. There are many types of existing spools, mainly divided into plastic spools, copper spools, cast iron spools, etc., among which , the plastic spool is widely used due to its stable performance, low cost, and according to the existing technology, the plastic spool is generally formed by molding, which has high cost, low precision, and slow production speed, which is not conducive to mass production and poor quality.

Abstract

The invention discloses a valve element injection mold. The valve element injection mold comprises a cover plate (1), an upper mold fixing plate (2), an upper mold plate (3), a lower mold plate (4), a mold leg (5), a spout (17) fixed to the cover plate (1), and a valve element (7), wherein a runner is arranged below the spout (17); the upper mold fixing plate (2) is fixed to the lower surface of the cover plate (1); the lower mold plate (4) is fixed to the upper surface of the mold leg (5); the upper mold plate (3) is located between the upper mold fixing plate (2) and the lower mold plate (4); a first protrusion (9), a second protrusion (10) and a third protrusion (11) are arranged on the outer side face of the valve element (7) in the axis direction of the valve element (7) in sequence from top to bottom; and annular grooves are formed in the outer side faces of the first protrusion (9), the second protrusion (10) and the third protrusion (11). The valve element injection mold is low in cost, high in precision, high in production speed, capable of achieving batch production and good in quality.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a valve core injection mold. Background technique [0002] The spool is a valve part that uses its movement to realize the basic functions of direction control, pressure control or flow control. There are many types of existing spools, mainly divided into plastic spools, copper spools, cast iron spools, etc., among which , Plastic spools are widely used due to their stable performance, low cost, and according to the prior art, plastic spools are generally formed by compression molding, which has high cost, low precision, and slow production speed, which is not conducive to mass production and poor quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above defects of the prior art and provide a valve core injection mold with low cost, high precision, fast production speed, mass production and good quality.
