Summary:The invention provides a simple preparation method of a stripping pattern mold for casting of a three-blade isometric screw inducer. By preparing an inducer mold and carrying out an appropriate sand excavation operation, a cover box mold and a stripping pattern blank are cast, and thus a stripping pattern plate is obtained. The cover box mold is combined with the stripping pattern plate, and a support frame, a connecting shaft, a guide shaft sleeve and a rotating rod are fabricated and constituted to obtain a whole set of mold. With this technological equipment, an inducer without parting surface may be cast by a sand mold casting method; thus, the problems of poor casting accuracy, high grinding difficulty and low yield of inducers are solved, and the production efficiency and casting precision of isometric screw inducers are significantly improved with reduced production costs. 本发明提出种三叶螺旋等距诱导轮铸造漏模模具的简易制备方法，通过制备诱导轮模具，并进行合适的挖沙操作，铸成盖箱模具和漏模毛坯，进而得到漏模模板；将盖箱模具和漏模模板结合，通过制作并组成支撑架、连接轴、导向轴套和旋转杆得到整套模具。该工艺装备可以用砂型铸造的方法铸造
