style="text-indent:25px">隨著塑料工業(yè)的發(fā)展，塑料制品的復(fù)雜性、精度等要求愈來愈高，對(duì)雙色周轉(zhuǎn)箱注塑模具材料也提出更高要求。對(duì)于制造復(fù)雜、精密與耐腐蝕性的塑料模，可采用預(yù)硬鋼（如PMS）、耐蝕鋼（如PCR）與低碳馬氏體時(shí)效鋼（如18Ni-250），均具有較好的切削加工、熱處理與拋光性能及較強(qiáng)度。此外，在選擇材料時(shí)還須考慮防止擦傷與膠合，如兩表面存在相對(duì)運(yùn)動(dòng)的情況，則盡量避免選擇組織結(jié)構(gòu)相同的材料，特殊狀況下可將一面施鍍或氮化，使兩面具有不同的表面結(jié)構(gòu)。</p><p style="text-indent:25px">周轉(zhuǎn)箱模具選材需要滿足三個(gè)原則，周轉(zhuǎn)箱模具滿足耐磨性、強(qiáng)韌性等工作需求，周轉(zhuǎn)箱模具滿足工藝要求，同時(shí)周轉(zhuǎn)箱模具應(yīng)滿足經(jīng)濟(jì)適用性。周轉(zhuǎn)箱模具條件要求：耐磨性，坯料在周轉(zhuǎn)箱模具型腔中塑性變性時(shí)，沿型腔表面既流動(dòng)又滑動(dòng)，使型腔表面與坯料間產(chǎn)生劇烈的摩擦，從而導(dǎo)致周轉(zhuǎn)箱模具因磨損而失效。所以材料的耐磨性是周轉(zhuǎn)箱模具基本、重要的性能之一。硬度是影響耐磨性的主要因素。一般情況下，周轉(zhuǎn)箱模具零件的硬度越高，磨損量越小，耐磨性也越好。另外，耐磨性還與材料中碳化物的種類、數(shù)量、形態(tài)、大小及分布有關(guān)。周轉(zhuǎn)箱模具生產(chǎn)的發(fā)展水平是機(jī)械制造水平的重要標(biāo)志之一。</p><div

style="text-indent:25px">周轉(zhuǎn)箱模具多用于熱固性塑料的成型。除此之外，還有泡沫塑料成型周轉(zhuǎn)箱模具、玻纖增強(qiáng)塑料低壓成型周轉(zhuǎn)箱模具等等。周轉(zhuǎn)箱模具設(shè)計(jì)制作的要求是：尺寸精確、表面光潔；結(jié)構(gòu)合理、生產(chǎn)效率高、易于自動(dòng)化；制造容易、壽命高、成本低；設(shè)計(jì)符合工藝需要，經(jīng)濟(jì)合理。周轉(zhuǎn)箱模具結(jié)構(gòu)設(shè)計(jì)和參數(shù)選擇須考慮剛性、導(dǎo)向性、卸料機(jī)構(gòu)、定位方法、間隙大小等因素。周轉(zhuǎn)箱模具上的易損件應(yīng)容易更換。對(duì)于塑料模和壓鑄模，還需要考慮合理的澆注系統(tǒng)、熔融塑料或金屬流動(dòng)狀態(tài)、進(jìn)入型腔的位置與方向。周轉(zhuǎn)箱模具必須是高精度的。慈溪市工具箱注塑模具生產(chǎn)公司</p><p
