di color mold design and injection molding need attention/notes 事项
di color mold is types plastics material in 同一台 injection molding machine upper injection molding, separation molding, usually sleeve/set mold formed, rear need 旋转180 degree, front 模不动, is product one-time mold. generally this type of process di material injection molding, need di color injection molding machine. di color mold design and injection molding need attention/notes has:
1, type and type 芯 运 water 布置尽 amount separation, and 均衡, 一样.
2, mold front in 心旋转180º rear, must and rear combined. design must attention/notes this 一点.
3, 99% 情况 is injection molding product hard separation, again injection molding product soft separation. is soft easy deformation.
4, sheet/plate water most good can design formed can demolding as. especially need attention/notes soft water demolding as is can 靠.
5, in design 时, fine di color mold injection molding machine parameters data, 如, most large thick degree, most small thick degree, 顶棍孔距离 and other.
6, injection molding 时, one-time injection molding product dimensions can large, make it in 第二次 molding can and type pressure more 紧, to function.
7, front 模 两 形状 is different, separation molding 1 types product. rear 模 两 形状完 full 一样. (attention/notes: has 不一样, need front slip block ensure rear 模一致)
8, attention/notes in 第二次 injection molding 时, plastics flow is 否会冲动第 one-time already molding good product, make its deformation? if has this can can, need method improvement.
9, is make types plastics “ viscous ” more 紧, need 考虑材 material between “ viscous property ”以 and mold surface coarse degree. di color mold injection molding has TPU; mold surface light slip, it 们“ viscous ‘ more 紧.
10, in design 第二次 injection molding type 腔时, is type 腔插（ or scratch ）伤第 one-time already molding good product 胶位, can design separation 避空. is must heavy 考虑每一处封胶位 strong/high degree, 即: in di color mold injection molding in, is has in large injection molding pressure lower, plastics deformation, 导致第二次 injection molding can can has generate can can?
