Second, the principle of energy-saving disk machine As the disc machine has a very abrupt process of mutation, the impact on the machine is very large, affecting the life of the entire injection molding system. At present, there are a large number of old equipment in domestic shoe-making enterprises. The degree of automation is low and energy consumption is high. Machines are generally designed for maximum production capacity. In fact, they often do not use as much power as they produce. The rotational speed of the oil pump motor remains unchanged, so the output power is almost constant, and there is a phenomenon of large horse-drawn carts in production. As a result, a lot of energy was wasted.

First, the working principle of the automatic disc type plastic injection molding machine The shoe-making enterprise's automatic disc type plastic injection molding machine, is the shoe-making enterprise's main one kind of common electricity equipment, the person calls the electric tiger. China is a big shoe country and has a lot of shoemaking equipment. The following mechanical characteristics of the automatic disc plastic injection molding machine (hereinafter referred to as: disc machine):
â—Ž This machine is used to produce all kinds of high-grade monochrome, bicolor and tricolor sports shoes, casual shoe soles, male and female children's shoes and other products.
â—Ž Raw materials are suitable for the production of various thermoplastic materials such as foam, such as PVC, TPR, etc.
â—Ž The machine is controlled by computer programs (single-chip microcomputer, PLC). The main and auxiliary machines have precise control, simple operation and easy maintenance.
â—Ž With the help of the pressure switch design, the closing mold master cylinder can quickly close the mold and establish the clamping force, so that each molding can not produce burrs and ensure the quality of the product.
â—Ž Proportional pressure control, independent operation of the die pressure, suitable for the production of different shots.
We adopt the variable-frequency operation technology of the disc machine. The inverter detects the pressure and flow signals from the computer board of the disc machine in real time. The pressure or flow signal of the disc machine is 0~1A. After the internal processing, it outputs different frequencies. , Adjust the motor speed, that is: output power and pressure and flow synchronization automatic tracking control, equivalent to the quantitative pump into an energy-saving variable pump, the original hydraulic system and the machine to run the power required to eliminate the original system of high pressure Loss of flow energy. Can greatly reduce the mold, mold vibration, stabilize the production process, improve product quality, reduce mechanical failure, extend the life of the machine, but also can save a lot of electricity.
Third, the characteristics of frequency conversion and energy saving 1) Simple operation, synchronous operation with the disc machine, without any adjustment;
2) High reliability: retain the original control method of the disc machine and the same oil circuit; adopt the mains/power-saving operation control mode to prepare for failure without affecting production;
3) Soft start: Reducing machine vibration, prolonging the service life of equipment and molds; effectively reducing noise and improving working environment; system heating significantly reduced, oil temperature stable; prolonging the service life of sealing components, reducing downtime maintenance rate, saving a lot Maintenance costs, while increasing the installed capacity of the transformer;
4) High rate of return: All investments will be recovered by electricity savings during approximately 6 to 12 months.
