         positive mold structure features is 凹模安装 in lower base/seat upper. 故无论 is parts material, 冲孔, also is its it 一 工序,工 parts or waste material can non 常方便 落入冲床工 as upper waste material in. therefore in design positive mold 时,就不必考虑工 parts or waste material toward. make design mold structure non simple, non use.

         positive mold structure advantages:

        (1)因 mold structure simple, can shrink short mold manufacturing cycle, has new product made and development.

        (2) use and repair relatively 方便.

        (3)安装 and adjustment 凸, 凹模间隙 relatively 方便(versus for mold 而言).

        (4) mold manufacturing cost low, has improve/increase enterprise 经济效益.

        (5) due to in tensile process in,始终存 in pressure force, therefore suitable for non 旋转体 parts 拉抻.

         positive mold structure disadvantages:

        (1) due to parts or waste material in 凹模孔 inner poly, increase 凹模孔 inner small force. therefore must increase thick,以提 high strength.

        (2) due to parts or waste material in 凹模孔 inner poly, therefore in generally lower,凹模刃口就必 must need processing material degree. in has lower, also need processing 凹模刃口 反面孔(出 material 孔). 因而即延 long mold made as cycle, also mold processing use.

         in in, in selection mold structure 时,应应 excellent selection positive mold structure. has in positive mold structure lower can meet/satisfy parts technology requirements 时,才 can using/adopting its it mold structure.
