ing surface is plicated curved surface and it has uneven step shape. The side gate is adopted. There are two reentrant structures in the area of A and B of the plastic part 1, the draft angle is zero in the area of C of the plastic part 1and there are six reentrant structures within the limit of Dand E of the plastic part 1. The corresponding corepulling mechanisms should be designed in the five places. There are three reentrant structures in the area of F, G and H of the plastic 2 and there are six reentrant structures within the limit of I and J of the plastic part 2. The corresponding corpulling mechanisms should be designed in the five places also. Thenten corepulling mechanisms will be placed in one mould. Sothe reasonable design of the corepulling mechanisms is the most important in the course of designing the injection mould.II. DESIGN OF ANGLE PIN COREPULLING MECHANISMS According to the structure feature of the plastic parts, sixangle pin corepulling mechanisms are designed in the area of A, B and C of the plastic part 1 and in the area of F, G and H of the plastic part 2. The mechanisms are distributed inFigure 2. Distribution of the angle pin corepulling mechanisms Taking the angle pin corepulling mechanism 1 shown in for example, the mechanism is mostly posed ofslide 1, angle pin 4, positioning screw 6, slide wedge 8, wear plate 5 and wear plate 7. The mechanism is shown in figure 3 When the mould is opened, the angle pin fixed in the fixed half of the mould guides the slide in the moving half of the mould. The slide moves outward along the slide way. The inclined plane of the cavity plate which is mated with the slide can ensure wedging the slide when the mould is closed. Considering the mould structure and process parameters, the inclined angle of the angle pin is 13176。 corepulling mechanism。2009 IEEE ICIMA 2009Application of Corepulling Mechanism in Injection Mould DesignHuang Guijian1, Li Xuemei2, 3, Wu Xiaoyu4, Li Jibin41.
