Electromagnetic Induction Heating Injection Molding Equipment Power Saver

Abstract

The invention belongs to the technical field of heating, and particularly discloses a power saver for an electromagnetic induction type heating injection molding machine. The power saver for the electromagnetic induction type heating injection molding machine comprises a power supply filter communicated with an alternating-current circuit, and is characterized in that the power supply filter is connected with a full-bridge PWM (Pulse Width Modulation) rectifying and filtering circuit; the full-bridge PWM rectifying and filtering circuit is connected with a buckle type electromagnetic coil through a control drive circuit; and a water cooling constant-temperature system and a connection switch system, which are connected in parallel, are mounted on the control drive circuit. The power saver for the electromagnetic induction type heating injection molding machine provided by the invention has the advantages that the structure is simple, the use is convenient, the damage on a human body by radiation can be effectively reduced, the problems that a transducer and a microcomputer are influenced can be solved, the power saving rate can reach 30-60%, and the safe energy conservation and the environmental friendliness can be realized.

Problems solved by technology

[0002] At present, various plastic machinery such as injection molding machines, granulators, and blow molding machines used by people are known as "electric tigers", all of which are heated by electric heating wires and electric heating tubes, and the utilization rate is extremely low, which can reach about 60%. , 40~50% of the heat energy is lost in the air, which cannot be fully utilized, which not only increases the cost of the manufacturing industry, pollutes the environment, but also easily causes unsafe factors such as leakage

[0003] With the development of science and technology, new technologies are constantly emerging. In recent years, a group of technical innovators have made various energy-saving transformation plans for the injection molding industry, but they have not been completely perfected. For example, communication and contact in temperature control are too frequent. Start, reducing the service life of the AC contactor; another example, there is no solution for high-frequency radiation interference, which will cause great harm and damage to the human body, frequency converter, and microcomputer, especially the problem of secondary pollution to the power grid.
