It can be seen that in order to make the overall appearance of the plastic parts not easy to leave traces of corrosion, the method of outer pouring is used to manufacture. The structure of side core pulling and ejector sleeve is used to achieve automatic separation. After experimental analysis, there is a pipe thread outside the plastic part, and a side core pulling is needed to be installed when working. The core is fixed on the sliding block of the pipe thread and the sliding block of the pipe thread is directly installed in the rectangular groove of the pipe thread, which can effectively ensure the precision and reliability of the rubber plastic part.<br>
