Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of throttle valves, and particularly relates to a throttle valve for an injection mold. Background Technique
[0002] A throttle valve is a valve that controls the fluid flow rate by changing the throttle section or throttle length. Combining a throttle valve and a check valve in parallel can form a one-way throttle valve. Throttle valves and one-way throttle valves are simple flow control valves. In a quantitative pump hydraulic system, when a throttle valve is combined with a relief valve, three throttle speed control systems can be formed, namely the inlet oil throttle speed control system, the return oil throttle speed control system, and the bypass throttle speed control system. The throttle valve does not have a flow negative feedback function and cannot compensate for the speed instability caused by load changes. It is generally only used in occasions where the load change is small or the requirement for speed stability is not high.
[0003] There are still some defects in the existing throttle valves for injection molds. During the use of most throttle valves for injection molds, the surface of the throttle valve cannot be dust-proofed, resulting in the generation of dust easily when controlling the valve size, increasing the friction between the passage and the valve, and affecting the service life. Therefore, we propose a throttle valve for an injection mold. Summary of the Utility Model

Inside the dust-proof cover, there is a first dust brush, and the first dust brush and the dust-proof cover are fixedly connected. Inside the dust-proof cover, there is a second dust brush, and the second dust brush and the dust-proof cover are fixedly connected. Inside the dust-proof cover, there are a plurality of first mounting bolts, and the first mounting bolts and the mounting plate are detachably connected. Inside the injection mold passage, there is a throttle valve body, and inside the throttle valve body, there is a first through hole.
