Injection molding of polymer processing technology has become the most commonly used methods and mass production of plastic products occupy a dominant position. The design of plastic injection molds fixation, the use of large plastic parts for mass production, so in order to save materials, hot runner technology, the best gate by Moldflow software analysis based on the selected best gate location, The use of hot runners turn in the form of cold runner, saving the mainstream Road, part of the plastic, reducing the cost. With side core pulling, though slightly more complicated structure, but can reduce the subsequent processing, reducing the production cycle. The use of a mold of a mold cavity, core mechanism
and the cooling water arrangement symmetrical, easy to install.
