④帶革紋、噴砂等外觀處理的塑件側(cè)壁應(yīng)加2°~3°的脫模斜度，視具體的咬花深度而定，一般的曬紋版上已清楚例出可供作參考之用的要求出模角。咬花深度越深，脫模斜度應(yīng)越大.推薦值為1°+H/°(H為咬花深度）.⑤插穿面和枕位面斜度一般為1°~3°*枕位、插穿、碰穿的區(qū)別枕位一般指分型面高低變化的一個特征。類似于一個枕頭。插穿指一個孔位由于內(nèi)有分型面高低變化，需要前后模對插實現(xiàn)孔位通透。分模前：分模后：利用插穿可以消除側(cè)孔倒扣。碰穿指孔位分型面平整無高低變化的一個分模特征。*柱子基本設(shè)計守則①設(shè)計柱子時，應(yīng)考慮膠位是否會縮水。A）柱子的縮水的改善方式1：改善前柱子的膠太厚，易縮水；改善后不易縮水。B）柱子的縮水的改善方式2：柱子足夠大時，可以在中間開孔減膠，以防縮水。如擔(dān)心柱子位置反面縮水，螺柱底部可設(shè)計火山口減膠。常用比較大可容滾動球大小來判定縮水與否。衡量公式：(D-T)/T*<>D為滾動球直徑T為一般膠厚柱子盡量不要單獨使用，應(yīng)盡量連接至外壁或與加強筋一同使用，目的是加強支柱的強度及使膠料流動更順暢。此外，因過高的柱子會導(dǎo)致塑膠部件成型時困氣，所以柱子高度一般是不會超過柱子直徑的兩倍半。。</p><div
