Embodiment

[0019] Example: such as figure 1 As shown, the electromagnetic heating system of the injection molding machine includes: the barrel 1 of the injection molding machine, the hopper, and the insulating material 4 covered on the barrel 1. The insulating material is made of ceramic fiber products. The insulating material 4 can prevent the heat from being lost after the barrel is heated. The electromagnetic induction coil 3 is wound in sections on the outside, and the electromagnetic induction coil 3 is provided with a shield 5. The shield 5 is mainly made of aluminum alloy. A temperature measuring point is arranged near each section of the electromagnetic induction coil, and the thermistor 2 is placed on the measuring point At the temperature point, the electromagnetic induction coil 3 is electrically connected to the same electromagnetic controller 6 in parallel, and the power supply is provided by the electrical control cabinet 7 . The electromagnetic controller includes a microp...

Abstract

The invention relates to an injector electromagnetic heating system, which comprises a material barrel and an electrical control cabinet. The system also comprises electromagnetic induction coils which are sectionally fired outside the material barrel, heat sensitive elements arranged on each temperature measuring point and an electromagnetic controller, wherein the electromagnetic induction coilgenerates an alternating magnetic field after being galvanized with high frequency and high voltage electricity; the temperature measuring points are arranged close to each section of the electromagnetic induction coils; the electromagnetic controller comprises a microprocessor and a peripheral circuit so as to convert power frequency current into high frequency and high voltage current, output the high frequency and high voltage current to the electromagnetic induction coil, monitor the temperature of the material barrel in a real-time mode and adjust the heating power of each section in time. The controller is integrated on a control board so as to realize control over a plurality of coils of one heating host machine, simplify the heating system, reduce the manufacturing cost and save 15 percent of electricity compared with the prior electromagnetic heating system.

Description

technical field [0001] The invention relates to a method and a system for heating an injection molding machine, in particular to a method and a system for electromagnetic heating technology. Background technique [0002] At present, most of the heating devices of injection molding machines use resistance heating. In this heating method, the heat generated by the resistance wire needs to be transferred to the heating component through heat conduction. During the heat conduction process, most of the heat will be lost, such as lost to the air. In the process, the heat conversion efficiency is low, resulting in a waste of electric energy. In addition, the resistance wire is easy to burn out due to high temperature aging, the service life is short, and the warm-up time is long. In view of the shortcomings of this heating method, someone proposed an electromagnetic heating method. The method is to pass a high-frequency and high-voltage current to the electromagnetic induction coi...
