Episode Synopsis "The part adopts two points of pouring, which reduces the flow of molten material"

This distance is set Must be related to the shape and size of the parts. When closing the mold, the sequence is reversed, and injection Automotive bumper mould is started after the closing of the mold. According to the traditional ejection method, if the ejector directly ejects the part, the ejector trace will be formed, which does not meet the product appearance requirements. The movable model cavity frame 11 and the fixed model cavity frame 14 are separated. According to the structural characteristics of the parts and the injection molding process, the mold is equipped with side gates on both sides of the gate, so that the material injection process in the entire injection process More balanced. In order to solve the appearance of spin marks on the surface of the part, a craft rib (see the craft rib in Figure 3 and the schematic diagram of the slider in Figure 4) is set at the butt joint of the two core-pulling sliders to make the material flow smooth, which better solves the defect and guarantees the appearance of the part Claim. The simple structure of the mold is shown in Figure
