(P34D1) We can classify the parting surface as being either flat or non-flat. Examples of the latter type include stepped, profiled and angled parting surfaces.(P34D2) 分型面是模具型腔中两块模板邻近型腔的部分互相贴合，形成一个封口，避免塑料从型腔中流失。 我们可以把分型面分为平面和非平面两类。后一种包括阶梯型，轮廓型和倾斜型分型面。 - * - CHAPTER 2 Parting Surface In general, the flat parting surface is the simplest to manufacture and maintain. It can be surface-ground, and is easily bedded down. .(P34D3) 一般平面分型面是加工和维护最方便的。可以用平面磨床和简单地铲削来完成。 To bed down a pair of mould plates is the process of marrying the two mould surfaces together. This is accomplished by blueing one surface, momentarily bringing the two plates together and subsequently removing any high spots which will be apparent on the non-blued surface. The plates are said to be bedded down when an even film of blue is transferred from one plate to the other. (P34D4) 铲削一对模板是共同研
