摘　　要：由于气液固三态的参与,气辅成型的冷却过程较为复杂。本文参照气辅成型的数学模型对该冷却过程工艺参数进行理想化假设,并对该模型进行简化及求解,得到了塑料制品在冷却过程中的温度场分布和冷却时间。As the participation of three states-gas, liquid and solid-the cooling process of Gas-assisted injection molding becomes comparatively complicated. This paper tries to obtain temperature distribution and cooling time of plastic products in the process by making an idealized hypothesis for parameters of the cooling process, with reference to the mathematical model of gas-assisted injection molding, which is simplified and solved in this paper...
