一般塑料注塑模具加工廠家進(jìn)行模具加工在選擇分型面的選擇會(huì)影響到開模后的注塑件是滯留在動(dòng)模型腔中，還是滯留在定模型腔中，進(jìn)而影響到產(chǎn)品能否順利脫模，還會(huì)影響到模具型腔的加工性。塑料注塑模具加工廠家分型面處是否會(huì)產(chǎn)生飛邊或分型面的痕跡線是否會(huì)影響到注塑件尺寸、形狀、壁厚、模具結(jié)構(gòu)、模具排氣及注塑件膜模。故選擇分型面時(shí)，要綜合考慮各方面影響因素、條件和要求，合理地選擇分型面。塑料注塑模具加工廠家分享模具加工在選擇分型面應(yīng)考慮的因素：
Generally, when plastic injection mold processing manufacturers select the parting surface for mold processing, it will affect whether the injection parts after mold opening are retained in the moving mold cavity or in the fixed mold cavity, and then affect whether the products can be demoulded smoothly, as well as the processability of the mold cavity. Whether there will be flash or trace line on the parting surface at the plastic injection mold processing factory, and whether it will affect the size, shape, wall thickness, mold structure, mold exhaust and film mold of injection parts. Therefore, when selecting the parting surface, we should comprehensively consider all influencing factors, conditions and requirements, and reasonably select the parting surface. Plastic injection mold manufacturers share the factors that should be considered in selecting parting surface for mold processing:
1、一般情況下，塑料注塑模具加工廠家注塑件應(yīng)滯留在動(dòng)模型腔中，越便于產(chǎn)品的脫模；
1. In general, the injection parts of plastic injection mold manufacturers should stay in the dynamic mold cavity, which is more convenient for product demoulding;
2、應(yīng)避開“障礙體”的阻礙，避免運(yùn)動(dòng)干涉，方便產(chǎn)品脫模和模具型腔的加工；
2. The obstruction of "obstacle body" shall be avoided to avoid motion interference, so as to facilitate product demoulding and mold cavity processing;
3、應(yīng)盡量設(shè)在不顯眼和易去除飛邊、毛刺及容易加工的位置上；
3. It shall be set in an inconspicuous and easy to remove flash, burr and easy to process position as far as possible;
4、應(yīng)設(shè)在無凹陷及圓弧R的切點(diǎn)之外的位置上；
4. It shall be set outside the tangent point of arc r without depression;
5、應(yīng)考慮到澆口位置的設(shè)置及其形狀；
5. The setting of gate position and its shape shall be considered;
6、有利于澆注系統(tǒng)和排氣系統(tǒng)的布置；
6. It is conducive to the layout of gating system and exhaust system;
7、不影響模具加工的尺寸及其精度；
7. It does not affect the size and accuracy of die processing;
8、應(yīng)考慮塑料的性能及填充條件；
8. The properties and filling conditions of plastics shall be considered;
9、應(yīng)考慮成型的工藝性及效率；
9. The processability and efficiency of molding shall be considered;
10、模具的結(jié)構(gòu)簡單、使用方便穩(wěn)定。
10. The die has the advantages of simple structure, convenient and stable use.
