阀针运动不畅原因分析
Causes of poor valve needle movement
1. 气压压力不足、气路不通或密封不好
pneumatic pressure is insufficient, or poorly sealed gas barrier
2. 缸体系统被咬死：缸体、分流板和喷嘴不同心，码模板积热太多
cylinder system has been killed: cylinder, manifold and nozzles of different heart, code templates accumulated heat too
3. 阀针与导套卡死：不同心或过热造成
valve needle and guide Taoka death: heart, or overheating caused by different
4. 阀针与导套之间有漏料，冷料包住了阀针
valve leakage between the needle and the guide sleeve material, cold material encase the valve needle
四、射不出胶的原因分析
Fourth, the cause misfires gel analysis
1. 浇口被杂质堵住了
gate blocked by impurities
2. 温度太低
temperature is too low
3. 热损失太大
large heat loss
4. 温控器显示的温度和实际温度有误差
shows the temperature of the thermostat and the actual temperature error
五、热喷嘴流延
Five hot nozzle casting
原因：熔化温度太高，浇口太大，浇口冷却不足，选用了不正确的热喷嘴类型处理：降低热喷嘴温度或模具温度，选用合适嘴头，加工正确的浇口尺寸

先检查针阀是否漏气，电磁阀是否排气不畅，阀针和阀针套间是否有炭化料卡住，这些地方检查后再根据时间情况做解决方法。具体可咨询我们，qq281011834
