         谓倒装 mold structure features is 凸模安装 in lower base/seat upper,故我们就必 must using/adopting elastic pressure material plant/unit will parts or waste material from upper lower. it is in base/seat upper,因而就存 in how to will inner parts or waste parts from in issues.

        倒装 mold structure advantages:

        (1) due to using/adopting elastic pressure material plant/unit, make made 出 工 parts 平整, surface quality good.

        (2) due to using/adopting material will parts or waste material from 凹模孔 in lower,因而工 parts or waste material in 凹模孔 inner poly, can decrease/reduce parts can waste material for 孔 涨 force. from can decrease/reduce 凹模 壁 thick, make outer dimensions shrink small,节约 mold material.

        (3) due to parts or waste material in 凹模孔 inner poly, can decrease/reduce parts or waste material for 模刃口 abrasion loss, decrease/reduce 凹模 刃 abrasion 次数, from improve/increase use lifespan.

        (4) due to parts or waste material in 凹模也 inner poly, therefore 也就没 has necessary processing 凹模 反面孔(出 material 孔). can shrink short mold made as cycle, reduce mold processing use.

        (5) due to pressure force in sheet/plate material has full by 拉入凹模 front function, therefore suitable for 旋转体体 tensile.

        倒装 mold structure disadvantages

        (1) mold structure relatively complex (versus for positive mold 而言).

        (2)安装 and adjustment 凸凹模 between relatively difficult (versus for positive 装模而言).

        (3)工 parts or waste material troubleshooting 麻烦(most good use pressure shrink gas will its 吹走).

         in selection mold structure is, has parts surface requirements 平整, outer 形轮廓 relatively complex, outer 形轮廓不 for 称, or material relatively thin 时 冲裁,以 and 旋转体 parts tensile 时,才 selection mold structure.
