在熔模铸造工艺过程中,蜡棒的制造虽不算重要,但也是不可缺少的。目前,国内熔模铸造蜡棒的制造,大多数是采用手工或以简单的工具,用沾蜡的方法制造的。这样制造的蜡棒,蜡层厚度不均、表面不整齐、凸凹不平,不利于蜡模的组合;蜡棒尺寸不一致;生产效率低,很难适应机械化大量生产的要求。为此,我们设计了一台结构如图所示的多工位制蜡棒机。 1.工作时序本机从上芯棒(金属、木质芯棒均可)开
In the investment casting process, wax rod manufacturing is not important, but it is also indispensable. At present, the manufacture of wax cast rods for investment casting in China is mostly made by hand or with simple tools and waxing methods. The manufactured wax stick has the advantages of uneven thickness, uneven surface, uneven surface and is not conducive to the combination of wax molds; the sizes of the wax sticks are inconsistent; the production efficiency is low and it is very difficult to meet the requirements of mass production of mechanization. To this end, we have designed a multi-station wax stick machine with the structure shown in the figure. 1. Working timing The machine from the mandrel (metal, wood mandrel can be) open
