DPDT型多向平动头在对开模水平加工、引伸模凸凹模合研加工中已取得良好效果。对开模,又称西瓣模,所模压的零件外形由上下模的两个型腔组成,中间分型。为了保证不出大的飞边和错箱,上下模的型腔在分型面上轮廓形状必须一致,位置必须正确。机加工困难 DPDT-type multi-directional head in the open mold horizontal machining, die punch punch research has achieved good results. On the mold, also known as the Western valve mode, the shape of the molded parts by the two mold cavity up and down, the middle type. In order to ensure that no big flash and the wrong box, the upper and lower cavity in the sub-surface profile of the shape must be consistent, the location must be correct. Machining difficult
