Method and device for determining opening time of precooling bin of frozen sand mold and precooling bin

The embodiment of the invention discloses a method and device for determining the opening time of a frozen sand mold precooling bin and the precooling bin. A frozen sand mold is divided into a plurality of cells through a preset sand mold three-dimensional model, and the freezing duration needed by the frozen sand mold is determined by judging whether the temperature of the cell with the highest temperature meets the target freezing temperature or not; the technical problem that in the prior art, the opening time of the precooling bin cannot be accurately controlled, so that the temperature of the frozen sand mold cannot meet the requirement is solved, and the technical effects that energy is saved in the freezing process, the working efficiency is improved, and the process cost is reduced are achieved. 本发明实施例公开了一种冷冻砂型预冷仓的开启时间确定方法、装置和预冷仓，通过将冷冻砂型利用预设砂型三维模型划分为多个单元格，并通过判断温度最高的单元格的温度是否满足目标冷冻温度来确定冷冻砂型所需要的冷冻时长，进而确定预冷仓的开启时间，解决了现有技术中无法对预冷仓的开启时间进行准确控制所导致的冷冻砂型的温度无法满足需求的技术问题，实现了冷冻过程的能量节约，且提高了工作效率、降低了工艺成本的技术效果。
