【正文】 opened after full packing and cooling. The moving plate of the injection machine moves back together with the moving half of the injection mould and the mould opened between the parting face of the mould. The plastic parts are pulled from the cavities of mould and stay with the moving half of the mould. The angle pins fixed in the cavity plate guide the six slides in the moving half of the mould to finish corepulling. When the mould is opened for a fixed distance, the moving half of the mould stops moving back. The ejector rods of the injection machine move ahead and push forward the ejector plate of the mould with the ejector rods, angle ejector rods. Then the plastic parts are pushed out of the injection mould and corepulling is acplished during the ejecting. When ejector rods of the injection machine move just for 120mm, the ejector mechanism stops moving and the plastic parts are taken out. The action of demoulding is pleted. When the mould is closed, the ejector rods of the injection machine move back. The mould ponents return to their original position in virtue of the return pins and the angle pins. The second working cycle begins after the mould is closed. V. CONCLUSION 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.
