注塑加工中,温度过高有什么影响?

注塑加工过程中,难免会温度特别高,温度高了会有很多不好的影响!今天小编就以济南注塑模具为例,为大家详细的总结一下注塑加工过程中,温度过高的影响!
In the process of injection moulding, it is inevitable that the temperature will be very high. If the temperature is high, there will be many adverse effects. Today Xiaobian takes Jinan Injection Mold as an example to summarize the effect of excessive temperature in injection processing in detail.
1,使机械产生热变形:液压元件中热胀系数不同的运动部件因其配合见习变小而卡死,引起动作失灵,影响液压系统的传动精度,导致部件工作质量变差。
1. Thermal deformation of machinery: the moving parts with different thermal expansion coefficients in hydraulic components are jammed because of their smaller cooperation with novices, resulting in movement failure, affecting the transmission accuracy of the hydraulic system, resulting in poor working quality of the components.
2,使油的粘度降低:注塑机温升过高将导致油的粘度降低,泄漏增加,泵的容积效率和整个系统的效率会显著降低,由于油的粘度降低,滑阀等移动部件的油膜变薄和被切破,摩擦阻力增大,导致磨损加剧。
2. Reduce the viscosity of oil: the high temperature of injection moulding machine will lead to the decrease of oil viscosity and leakage, the volume efficiency of the pump and the efficiency of the whole system will be significantly reduced. Because of the decrease of oil viscosity, the oil film of moving parts such as sliding valves will become thinner and cut, and the friction resistance will increase, which will lead to worsening.
3,使橡胶密封件变形:注塑机温升过高会使橡胶密封件变形,加速老化失效,降低密封性能及使用寿命,造成泄漏。

3. Deformation of rubber seals: Excessive temperature rise of injection moulding machine will deform rubber seals, accelerate aging failure, reduce sealing performance and service life, and cause leakage.
4,加速油液氧化变质:注塑机温升过高会加速油液氧化变质,析出沥青物质,降低液压油的使用寿命,析出物堵塞阻尼小孔和缝隙式阀口,导致压力阀卡死而不能动作,金属管路伸长而弯曲,甚至破裂等。
4. Accelerate oil oxidation deterioration: Excessive temperature rise of injection moulding machine will accelerate oil oxidation deterioration, precipitate asphalt, reduce the service life of hydraulic oil, blockage of damping orifice and slot valve orifice, lead to pressure valve stuck and unable to move, metal pipeline elongation and bending, or even rupture.
5,导致部件工作质量变差:注塑机温升过高会导致部件工作质量变差,油中溶解空气逸出,产生气穴,致使液压系统工作性能降低。
5. Cause parts work quality deterioration: high temperature of injection moulding machine will lead to parts work quality deterioration, dissolved air escaping from oil, resulting in cavitation, resulting in hydraulic system performance degradation.
