Notice of injection moulding machine
Injection molding machine temperature rise is too high, five major hazards: the machine produces thermal deformation, oil viscosity decreases, rubber seals deformation, accelerate oil oxidation deterioration, but also make the air component pressure reduction.One of the hazards: causes the machine to produce thermal deformationIn the hydraulic component, the moving parts with different thermal expansion coefficients are jammed because of the small clearance between them, which results in malfunction and influences the drive accuracy of the hydraulic system, resulting in the poor quality of the parts.Hazard two: reduce the viscosity of the oilThe high temperature rise of the injection molding machine will lead to lower viscosity of the oil and leakage increase. The volume efficiency of the pump and the efficiency of the whole system will be significantly reduced. As the viscosity of the oil decreases, the oil film of the moving parts, such as the slide valve, is thinned and cut, and the frictional resistance increases, leading to increased wear.Hazard three: deform rubber sealsThe temperature rise of the injection molding machine is too high, it will deform the rubber seal, accelerate the aging failure, reduce the sealing performance and service life, and cause leakage.Four of the hazards: to accelerate the oxidation of oilThe temperature rise of the injection molding machine is too high, it will accelerate the oxidation of the oil, precipitate the asphalt material, and reduce the service life of the hydraulic oil. The precipitate blocks the damping orifice and the slit valve opening, causing the pressure valve to stop and cannot move, and the metal pipe lengthens and bends, and even breaks.
