Abstract

The invention discloses an ejection device of filtering impurities, which includes a material inlet, an ejection pipe, an ejection nozzle and a filtering screen. The material inlet is arranged on the top of an ejection mechanism. The ejection pipe is arranged on the upper part of the ejection mechanism. The ejection nozzle is arranged on a lower end of the ejection mechanism and is used for ejecting rubber. The filtering screen is arranged between the ejection pipe and the ejection nozzle. The filtering screen is provided with a plurality of holes. In the invention, by means of addition of the filtering screen in the ejection mechanism, solid impurities mixed in molten rubber can be effectively blocked, thereby significantly increasing the quality of a rubber product and solving a problem that the solid impurities are difficult to removal in a rubber preparation process.

Description

technical field [0001] The invention relates to the technical field of rubber machinery, in particular to an injection device for filtering impurities. Background technique [0002] The rubber injection molding machine is a machine that can heat the rubber raw material to a molten state, then inject the molten rubber into the mold under pressure, and solidify and form it. [0003] At present, the injection mechanism of the known rubber injection molding machine is as follows: figure 1 As shown, including injection tube, feed port and injection nozzle. During the rubber injection molding process, the molten rubber may be doped with solid impurities such as iron filings, and the pipeline of the injection mechanism cannot filter the solid impurities. After the rubber mixed with impurities is injected through the injection nozzle, it will affect the rubber product. the quality of. Contents of the invention [0004] The invention aims at the problems existing in the prior ar...
