How to deal with excessive temperature rise of injection molding machine?
(1) According to different load requirements, frequently check and adjust the pressure of the relief valve to make it just right.
(2) Reasonable selection of hydraulic oil, especially the viscosity of the oil. When conditions permit, try to use a lower viscosity to reduce viscosity friction loss.
(3) Improve the lubrication conditions of moving parts to reduce friction loss, which is helpful to reduce working load and heat.
(4) Improve the assembly quality and self-precision of hydraulic components and hydraulic systems, strictly control the fitting clearance of fittings and improve lubrication conditions. The sealing material with small friction coefficient and improved sealing structure are used to reduce the starting force of the hydraulic cylinder as much as possible to reduce the heat generated by mechanical friction loss.
(5) If necessary, add a cooling device.
