There is a lateral boss at the lowe

There is a lateral boss at the lower hanging foot of the plastic part, which is perpendicular to the demolding direction, which prevents the molded plastic part from being ejected from the demoulding. In this regard, the core pulling distance should first be determined, a safe and reliable distance should be estimated, and the distance should be determined according to the actual situation. Considering many factors, it is necessary to adopt a structure in which the bending pin and the slide block are installed on the movable mold at the same time, and the relative movement between the four-wire bending pin and the side core slide block with the help of the ejection mechanism, and then completes the lateral parting and core pulling action. The side slider needs to adopt a combined structure, which can save precious metal materials, reduce costs and facilitate processing and manufacturing. According to the composition of the lampshade, the slider and the side core are designed separately, and then reassembled together. Adopt groove positioning and screw connection.
