style="text-indent:25px">周轉(zhuǎn)箱模具與機(jī)筒連接處漏料：產(chǎn)生的原因有：兩零件的連接配合處加工精度低。配合面粗糙；配合面與模具體中心線垂直精度低。連接處兩接觸面不清潔，有異物。故障解決方法有：重新修配模具體結(jié)合面，提高配合面光潔程度；保證配合面與模具體中心線的垂直度，檢修、去除兩接觸面污物及異物。拆卸困難：產(chǎn)生的原因有：周轉(zhuǎn)箱模具體內(nèi)組合零件間有溢料現(xiàn)象。裝配前各配合零件沒有毛刺。連接堅(jiān)固螺栓裝配前沒有涂硅油。零件變形。故障解決方法有：重新制造，提高配合零件的精度。裝配前將零件清洗干凈。螺栓裝配前涂耐高溫硅油。</p><p 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，對雙色周轉(zhuǎn)箱注塑模具材料也提出更高要求。對于制造復(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，如兩表面存在相對運(yùn)動的情況，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)。周轉(zhuǎn)箱模具的溫度過高，會使制品在脫模過程中和脫模后發(fā)作變形，使其形狀和標(biāo)準(zhǔn)精度下降。</p><div
