劈箱模板混合造型方法是我厂所生产M210型内圆磨床床身时,学习了各兄弟厂各项先进经验的成果而推行的,它的特点是具有多种先进造型方法,如泥型盖箱,在侧箱圈及底箱采用了CO_2干燥及烘模砂表面干燥的方法;在木模工艺上采用了劈模多块模型;主要将木模分成六块,而砂型也跟着木模分块造型;在铸件侧面形状复杂处结合了组芯造型。劈箱模板造型要此原来单独模型造型在产量上可提高二倍以上,而生产周期和砂箱工具的周转期可以缩短二天,并且又可节省金属材料的消耗;同时,解决了烘房面积不足的困难,且在操作上降低了劳动强度。现将我厂M210型内圆磨床床身采用劈箱模板混合造型铸造工艺简单介绍如下: Split box template mixing modeling method is produced by our factory M210-type internal grinder bed, learning the results of the various advanced experience of the Brother plant and the implementation of its features is a variety of advanced modeling methods, such as mud-type cover Box, in the side of the box ring and the bottom of the box using CO_2 drying and baking sand surface drying method; in the wood mold process using a split mold multi-block model; the main wood mold into six, while the sand mold followed by wood mold Block shape; the shape of the casting complex side of the combination of core shape. The split box template modeling to the original single model shape in the output can be increased more than two times, and the production cycle and sand box tool turnover can be shortened two days, and can save the consumption of metal materials; the same time, to solve the drying room area Of the difficulties, and in operation to reduce the labor intensity. Now I plant M210-type internal grinder bed using split box template casting molding process is briefly described as follows:
