Example Embodiment

[0016] The present invention is described in further detail below in conjunction with accompanying drawing and embodiment:

[0017] see figure 1 , which is a schematic diagram of the overall structure of the injection molding machine in the prior art. The horizontal injection molding machine includes a body 1, a hydraulic system motor 2, a clamping cylinder 3, a fixed template 4, a mold clamping mechanism 5, a tie rod 6, a movable template 7, and a forming mold 8 , fixed template 9, barrel, screw and electric heating device 10, hopper 11, screw reduction box 12, drive screw motor 13, injection cylinder 14, metering device 15, injection mobile cylinder 16, console 17. Because the electric heating device is used in the prior art, the outer wall of the steel barrel is wrapped by the resistance wire, and the high temperature is generated by the resistance wire itself, and then the heat is slowly transferred from the high temperature of the outer surface of the steel barrel to the ...

Abstract

The invention provides a magnetic fusion heating system, which is characterized by sequentially comprising a metallic screw, a ceramic machine barrel, a stainless steel support barrel, a ceramic fiber thermal insulating layer, a magnetic fusion cable and a magnetic fusion electric cabinet. A steel machine barrel is replaced by the ceramic machine barrel; a non-contact electromagnetic induction heating mode is adopted, heat is directly produced on the steel screw, the interior of the machine barrel is uniformly heated, temperature is quickly raised and reduced, and the efficiency of about 95 percent can be achieved; and a running part is at low temperature, so that limitation on the service life does not exist.

Description

Technical field: [0001] The invention relates to the field of electromagnetic heating, in particular to a magnetic fusion heating system. Background technique: [0002] Currently on the market, domestic and foreign imported plastic machines (injection molding machines, extruders, blow molding machines) are heated by traditional contact resistance, that is, direct heating electric heaters wound with resistance wires. [0003] There are many disadvantages in using the traditional heating coil: First, the heating coil will dissipate heat to the surrounding air, and a large amount of heat will be lost in the external space, resulting in a waste of electric energy, and it will also affect the ambient temperature. If the ambient temperature is too high, there will be unsafe factors. It is unfavorable for the surrounding staff; in addition, this traditional heating method is transmitted through contact, which affects the heating efficiency. On average, only 30%-70% of the efficienc...
