The mould structure with two cavities is designed and the working process of the injection mould is discussed. The mould structure is plicated. Ten corepulling mechanisms are designed reasonably in one mould and demoulding of the plastic parts is realized. Many inserts and standard parts are used in the injection mould, so the economical efficiency of the injection mould is well and the injection mould can be maintained conveniently. The injection mould is already in mass production. Industrial practice proves that the action of the corepulling mechanisms, ejector mechanisms and resetting mechanisms is stable and reliable. The plastic parts produced can meet the customers’ technical requirements. Keywords injection mould。 slide。and the inclined angle in the cavity plate is 15176。which ensures the realization of the corepulling and the better power distribution. The angle ejector guide block is made of nickel bronze and is fixed in the core plate. The mould is easily maintained and the precision of the angle ejector rod is ensured by using the angle ejector guide block. The angle ejector rod is fixed in the angle ejector slide which moves along the slide way of the ejector retainer plate. Whenthe mould is opened, the angle ejector rod moves with theejector retainer plate. The angle ejector block moves ahead with the angle ejector rod and moves in the side direction. So the corepulling is achieved. The angle ejector block returns to its original position in virtue of the angle ejector rod which is driven by the ejector retainer plate.IV. OVERALL STRUCTURE AND WORKING PROCESS OF THEINJECTION MOULDThe mould structure is shown in figure 6. The layout of two cavities in one mould and side gate are adopted. The ten corepulling mechanisms shown in figure 6 is reasonably designed and pact in terms of structure.Figure 6. Mould structureThe whole working process of the mould is as follow:The melt plastic flows into the cavity of the mould throughthe feed system and the mould is opened after full
