1.简介 我们将把讨论局限于卧式冷室压铸过程,着眼于实际铸造操作以及下列机器部件;液压压射装置,压射冲头/压射室组件和模具,这些部件,就数量和质量而言,在铸件的生产中都至关重要(见图4)。 提高生产率意味着以更低的成本生产更多的铸件,例如,更快地开始生产,生产周期更短,废品率更低,减少最后检验要求以及减低由于差错而造成的耗费等等。 1. INTRODUCTION We will limit the discussion to the horizontal cold chamber die-casting process, focusing on the actual casting operation as well as the following machine components; the hydraulic injection unit, the shot punch / shot chamber assembly and the die, In terms of casting production are crucial (see Figure 4). Increasing productivity means producing more castings at a lower cost, for example, getting started faster, with shorter production cycles, less rejects, fewer final inspection requirements and less errors due to errors.
