In fact, a pair of molds is a heat exchanger, the heat enters the mold from the melted plastic, and then enters the continuous circulation cooling medium - ice water, with only a small part of air and the pressure mold of the injection molding machine. A considerable part of the plastic forming cycle is used for cooling, sometimes more than 80% of the plastic forming cycle, so it is absolutely necessary to control the cooling time to the minimum. For example, the molding cycle of a set of moulds is generally 20 seconds. If the cooling water of the original cooling tower is cooled by the chiller, it can be shortened to 16 seconds.
雖然更初選擇配備了冷水機的價格較高，但它可以增加20%的產量，從長遠來看，可以得到很多好處。那么如何選擇冰水能量呢?由上圖可知，它與成型數據的比熱容，膠水的溫度，重量，脫模的溫度有關。普通注塑模具冷卻,冰水選擇0.1 ~ 0.2 mpa的壓力,可以滿意需求,和冷水的微機全功能功能滿意這個需求,當需求大于0.2 mpa的壓力,需要單獨計劃,為了使用相應的壓力泵來滿足系統供水需求。
Although the initial choice of equipped with chiller has a high price, it can increase the output by 20% and get many benefits in the long run. So how to choose ice water energy? From the above figure, it is related to the specific heat capacity of molding data, glue temperature, weight and mold release temperature. For the cooling of common injection mold, the pressure of 0.1 ~ 0.2 MPa can satisfy the demand, and the computer full function of cold water can satisfy the demand. When the demand is greater than 0.2 MPa, it needs to be planned separately, in order to use the corresponding pressure pump to meet the water supply demand of the system.
