      熱流道閥針運動不暢不得原因是什么呢?

      2019-01-11 17:48:13

      閥針運動不暢原因分析
      Causes of poor valve needle movement
      1. 氣壓壓力不足、氣路不通或密封不好
      pneumatic pressure is insufficient, or poorly sealed gas barrier
      2. 缸體系統被咬死:缸體、分流板和噴嘴不同心,碼模板積熱太多
      cylinder system has been killed: cylinder, manifold and nozzles of different heart, code templates accumulated heat too
      3. 閥針與導套卡死:不同心或過熱造成
      valve needle and guide Taoka death: heart, or overheating caused by different
      4. 閥針與導套之間有漏料,冷料包住了閥針
      valve leakage between the needle and the guide sleeve material, cold material encase the valve needle
      四、射不出膠的原因分析
      Fourth, the cause misfires gel analysis
      1. 澆口被雜質堵住了
      gate blocked by impurities
      2. 溫度太低
      temperature is too low
      3. 熱損失太大
      large heat loss
      4. 溫控器顯示的溫度和實際溫度有誤差
      shows the temperature of the thermostat and the actual temperature error
      五、熱噴嘴流延
      Five hot nozzle casting
      原因:熔化溫度太高,澆口太大,澆口冷卻不足,選用了不正確的熱噴嘴類型處理:降低熱噴嘴溫度或模具溫度,選用合適嘴頭,加工正確的澆口尺寸
