The characteristics of injection molding machines and how to deal with excessive temperature rise of injection molding machine?

2020-10-12

The characteristics of injection molding machines 

1. Two-color injection molding machine

The injection molding machine which can inject two colors at one time can meet the appearance requirements of consumers and can make users more comfortable to use the products.


2. Multi-station molding machine

The injection device and the mold clamping device have two or more working positions, and the injection device and the mold clamping device can also be arranged in various ways.


3. Electric injection molding machine

The all-electric injection molding machine can not only meet the needs of special applications, but also have more advantages than ordinary injection molding machines.

Another advantage of the all-electric injection molding machine is that it can reduce noise, which not only benefits the workers, but also reduces the investment and construction costs in the soundproof production workshop.


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.
