山东模具公司冷水机是如何选择的?

来源:    发布时间:2019-10-30 16:40:00    点击:

  事实上,一对模具是一个热交换器,热量从熔化的塑料进入模具,然后从模具进入连续循环的冷却介质——冰水,只有一小部分空气和注塑机的压力模版。相当一部分的塑料成型周期是用来冷却的,有时超过80%的塑料成型周期,所以绝对有必要把冷却时间控制到。例如,一套模具的成型周期一般为20秒,如原冷却塔的冷却水到冷水机进行冷却,则可缩短至16秒。
  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.

  虽然更初选择配备了冷水机的价格较高,但它可以增加20%的产量,从长远来看,可以得到很多好处。那么如何选择冰水能量呢?由上图可知,它与成型数据的比热容,胶水的温度,重量,脱模的温度有关。普通注塑模具冷却,冰水选择0.1 ~ 0.2 mpa的压力,可以满意需求,和冷水的微机全功能功能满意这个需求,当需求大于0.2 mpa的压力,需要单独计划,为了使用相应的压力泵来满足系统供水需求。
  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.
