Vertical rubber injection molding machine feature

The characteristics of the proportional valve control oil circuit of vertical rubber injection machine:

1.After the oil pump motor is running, it runs at full speed and high load, and then the proportional valve sets the required pressure and flow for each level. However, in a production cycle of the injection molding machine, only the motor loads in the high-voltage mold clamping and melting stages are relatively large, while the motor loads in other stages are generally small. In other stages, the oil pump motor provides a constant flow at a constant speed, and excess hydraulic oil flows back through the relief valve. generate unnecessary waste.

2. The characteristics of the on-off valve control oil circuit:

The power of the oil pump motor is allocated according to the larger load during its operation. After the oil pump motor is running, the pressure and flow are not set. During the working stages of mold clamping, feeding injection, glue melting, pressure holding, cooling and mold opening, the corresponding directional switch valve in the oil circuit is opened, and the overflow valve works at full flow. When cooling and discharging, the directional switching valve is closed, the overflow valve is opened, and all flow back, resulting in waste.

Energy saving analysis of vertical rubber injection molding machine;

During the cooling and discharging process, the load of the hydraulically driven equipment represented by the vertical rubber injection machine is almost zero, and the cooling and discharging time accounts for 30-60% of the entire cycle. According to previous work experience, in terms of injection molding machines. Energy losses due to cooling and discharge flooding can be as high as 30%-65%. The power consumption of the oil pump motor of the injection molding machine accounts for 60%-75% of the total power consumption of the equipment, which has the potential for energy saving. Energy-saving and low-carbon life itself should become a habit of people's life. Regardless of the next power supply situation, we should implement the awareness of energy saving and emission reduction into our daily life. From a macro perspective, green and low-carbon is the only way for sustainable development. Striving for the peak of carbon dioxide emissions in 2030 is not only China's commitment to the world, but also an endogenous need for China's economic transformation.
