Die-casting mold temperature field is a key factor affecting the die casting quality and die life . Due to solidification shrinkage of the die castings in the solidification forming process , so the distribution of the temperature of the mold is a great influence on the dimensional accuracy and surface quality of the die casting . This article is from the point of view of heat transfer , a systematic analysis of die - casting mold spray forming process cooling mechanism . And three - dimensional castings reasonable simplified means of finite element analysis , rectangular box class die casting mold temperature field simulation . By contrast , were studied molten metal pouring temperature of 650 ° C , 670 ° C , 700 ° C , mold preheat temperatures were 180 ° C , 200 ° C , 240 ° C conditions , the shape of the die casting and mold structure its temperature field impact, and compared with the actual experimentally measured temperature distribution . Considering the temperature gradient of the mold , heating rate , the forming process parameters , select the parameters of the casting process requirements , and therefore a method to control mold temperature field . To apply this method to the actual production , and gas plug body die castings as a typical product resulting mold temperature field control method , applied to the the gas plug body structure of die-casting mold design and casting process parameters selection .
