找專業的大連模具加工就選斯達森精密模具

  滾塑成型工藝的方法是先將塑料加入模具中，然后模具沿兩垂直軸不斷旋轉并使之加熱，模內的塑料在重力和熱能的作用下，逐漸均勻地涂布、熔融粘附于模腔的整個表面上，成型為所需要的形狀，給冷卻定型而制得。模具加工的(de)(de)精(jing)細化使加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)設備(bei)(bei)的(de)(de)復合性、高(gao)(gao)效性更加(jia)(jia)引人關注(zhu)。高(gao)(gao)速銑削具有的(de)(de)可(ke)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)高(gao)(gao)硬材料、加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)平穩、切削力小、工(gong)(gong)(gong)(gong)(gong)件升溫變形小等(deng)諸多優(you)點(dian)使模(mo)(mo)(mo)具企(qi)業對高(gao)(gao)速加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)日(ri)益(yi)重視。模(mo)(mo)(mo)具成型(xing)(xing)(xing)零(ling)件的(de)(de)日(ri)漸大(da)(da)(da)型(xing)(xing)(xing)化和零(ling)件的(de)(de)高(gao)(gao)生產率要求(qiu)一(yi)(yi)模(mo)(mo)(mo)多腔(qiang)，致(zhi)使模(mo)(mo)(mo)具日(ri)趨大(da)(da)(da)型(xing)(xing)(xing)化，大(da)(da)(da)噸位的(de)(de)大(da)(da)(da)型(xing)(xing)(xing)模(mo)(mo)(mo)具可(ke)達100噸，一(yi)(yi)模(mo)(mo)(mo)幾百腔(qiang)、上千腔(qiang)，要求(qiu)模(mo)(mo)(mo)具加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)設備(bei)(bei)大(da)(da)(da)工(gong)(gong)(gong)(gong)(gong)作臺、加(jia)(jia)大(da)(da)(da)Y軸Z軸行程、大(da)(da)(da)承重、高(gao)(gao)剛性，高(gao)(gao)一(yi)(yi)致(zhi)性。

  尺(chi)寸精度(du)是用尺(chi)寸公差來控制的(de)。尺(chi)寸公差是模(mo)具(ju)加(jia)工中(zhong)零件(jian)尺(chi)寸允許的(de)變動量。在基本尺(chi)寸相同的(de)情(qing)況下,尺(chi)寸公差與愈小,則尺(chi)寸精度(du)愈高。加(jia)工精度(du)要求(qiu)高一付模(mo)具(ju)一般是由凹模(mo)、凸模(mo)和模(mo)架組成,有(you)些(xie)還可能(neng)是多件(jian)拼(pin)合模(mo)塊。于是上、下模(mo)的(de)組合,鑲塊與型腔的(de)組合,模(mo)塊之間的(de)拼(pin)合均要求(qiu)有(you)很高的(de)加(jia)工精度(du)。精密模(mo)具(ju)的(de)尺(chi)寸精度(du)往往達μm級。仿(fang)(fang)(fang)形(xing)加(jia)工模(mo)具(ju)生產中(zhong)有(you)時既沒有(you)圖樣,也(ye)沒有(you)數(shu)據,而且(qie)要根(gen)據實物(wu)進行(xing)仿(fang)(fang)(fang)形(xing)加(jia)工。這就要求(qiu)仿(fang)(fang)(fang)制精度(du)高,不變形(xing)。
