Description
Technical field
The utility model relates to a kind of electromagnetic induction heater, on particularly a kind of barrel periphery that solenoid is installed in injection molding machine, and in solenoid, feed high-frequency alternating current, the eddy-current heating that utilizes metalwork barrel autonomous induction to produce is to the injection molding machine electromagnetic induction heater of the heating of the particles in barrel and the barrel.
Background technology
Injection molding machine is a kind of widely used plastic processing machinery, use face is wide in a large number, but existing injection molding machine all still is by being wrapped in the outer resistance wire energising of barrel, heating, and with conducting the mode that heats, with heat transferred to barrel, conduct heat by barrel and to make plastic rubber material fusion in the barrel, inject and be injection molded into product, the heat of its outer ring of this kind heat exchange pattern all is lost in the air greatly, heat conduction losses is big, take, the heat efficiency is low, and cause electric leakage because of self heating power can produce insulation ageing problem, and also can cause the rising and the pollution of ambient temperature simultaneously, influence health of operators.
Patent No. CN01256319.6 " injection molding machine gun barrel electromagnetic eddy heating arrangement " just provides a kind of and the original conduction mode of heating of injection molding machine has been improved to the electromagnetic induction heating mode gun barrel is heated, but its adopts be with plurality of electromagnetic iron directly axially, be spaced the structure that is fixed on the gun barrel, need process a lot of metal shells of organizing electromagnet and being wrapped in electromagnet, processing, installation bother, workload is big.If will keep in repair, change electromagnet also need allow injection molding machine stop to produce just to finish for a long time, to have influenced the work of injection molding machine.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of injection molding machine electromagnetic induction heater is provided, it is simple in structure, easily installation, dismounting, easy to maintenance quick, low cost of manufacture, be installed on the barrel of injection molding machine and the supporting use of electromagnetic induction heater control cubicle, greatly reduce the ambient temperature of injection molding machine, improved condition of work, improved the heat efficiency, power savings is remarkable.
The technical scheme in the invention for solving the above technical problem is, the injection molding machine electromagnetic induction heater, comprise the electromagnetic induction heater control cubicle that is installed on the injection molding machine, and two outputs of electromagnetic induction heater control cubicle are connected with the two ends of solenoid, described solenoid, two coils that turn to by insulated conductor, be close to respectively on the inwall of two halves shell, also clog on the outer surface of coil and be fixed with the two halves housing that heat-insulation layer constitutes, and the two halves housing is enclosed within and is fixed into housing on the barrel, and the housing more than 1 and 1 is installed on the described barrel.
Compared with prior art, advantage of the present utility model is: this electromagnetic induction heater is except that the power and energy saving advantage with electromagnetic induction heating, also adopted directly because of it coil is close on the two halves shell that is fixed on plastic production, self does not generate heat coil, long service life.Also between coil and half shell, add the magnetic stripe that is lined with tape insulation, shielded AC magnetic field laterally and improved the intensity and the heat efficiency in coil generation magnetic field again.Also at the outer surface filling heat-insulation layer of coil, the heat that barrel is produced is difficult for being dispersed in the air, has improved the heat insulating ability and the heat efficiency of barrel again in addition.Coil and half shell all can be processed separately, and easily processing, be assembled into integral body then, with screw the two halves housing being embraced cover again during use is fixed on the barrel, fast quick-detach, transposing, installation and maintenance both be convenient to, do not influence the work of injection molding machine again, energy-saving effect significantly reaches more than 30%, greatly reduces production cost.
