用型板造型可以提高鑄件的質量和产量。我厂过去曾在联接器、側架等大批生产的零件中采用过型板造型法。但是由于型板、模型和砂箱的制造复杂(需要用金屬型和經过加工带銷眼的标准砂箱),成本很高,在中小批生产中,使用这种方法就很不合算了。最近我們根据壳型鑄造方法,把型板加以改进。改进后,就不需要特制金屬型和带銷眼的砂箱,这样就非常适合于中小批生产的手工生产了。
With the template shape can improve the quality and production of castings. I plant in the past in the coupling, side racks and other mass production of parts used in the modeling method. However, the cost is high due to the complicated manufacture of formwork, molds and sand boxes (metal and standard flask with dowel pins), which is not cost effective in small to medium batches. Recently, we have been based on the shell casting method, the template to be improved. After the improvement, you do not need special metal and pin-shaped flask, so it is very suitable for small and medium batch production by hand.
