Abstract
The utility model provides an electromagnetic heating device of an injection molding machine. The electromagnetic heating device comprises a plurality of electromagnetic heating controllers, a coil and a heat insulating layer, wherein the coil is wound on the heat insulating layer; the electromagnetic heating controllers are connected with the coil; the quantity of the electromagnetic heating controllers is two to six; and the coil is high-temperature resistant. The electromagnetic heating device has the advantages that a heating body heats close to the plastic particles and heating is rapid. As the exterior is wrapped with the heat insulating layer, the heat volatilization is small, the heating efficiency is high, operators are prevented from being scalded and the electromagnetic heating device is safe and reliable.
Description
Technical field
The utility model relates to the injection machine firing equipment, particularly relates to a kind of electromagnetic heating device of injection machine.
Background technology
In injection-moulding device, electrical heating is one of injection machine capital equipment.Most domestic producer adopts resistor disc to preheat at present, and heating is slow, and power consumption is high, and heater exposes affects surrounding working environment, and has the potential safety hazard of scalding operating personnel.Because resistor disc heating process is to heat first body and the feed nozzle body of injection portion, then by body heat is delivered on the plastic grain, plastic grain is melted, thus because body need to absorb heat heat time heating time longer.Heater exposes and causes heat very large to aerial volatilization in addition, so the efficiency of heating surface is very low.
Also has in addition a kind of use quartz ampoule heating, but it is more out of order than being easier to heating with quartz ampoule, because belonging to heat, the quartz ampoule heating transmits mode of heating, generate heat later on again with the heat transferred barrel by quartz ampoule, quartz ampoule is easy to break down because oxidation occurs excess Temperature, quartz ampoule heat hot loss ratio is larger simultaneously, very the waste electricity.
Summary of the invention
The purpose of this utility model is for above-mentioned existing problems, provides a kind of for injection machine electric heating energy-saving modification scheme, and this scheme device structure is simple, easy to implement, makes injection machine injection portion body self-heating.The heater outside adds wraps up in insulation material, avoids heat to distributing in the air.Reach energy-conservation, the purpose of safety.
The technical solution of the utility model: a kind of electromagnetic heating device of injection machine, consisted of by several electromagnetic heating controllers, coil, heat-insulation layer, coil winding is on heat-insulation layer, and electromagnetic heating controller is connected on the coil.
Further, described electromagnetic heating controller is 2 to 6.
Further, described electromagnetic heating controller is 4.
Further, described coil is high temperature resistant coil.
Advantage of the present utility model: heater generates heat near plastic grain, and heating fast.The outer wrap heat-insulation layer, the heat volatilization is little, and the efficiency of heating surface is high, avoids the scald to operating personnel, and is safe and reliable.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure:
1, electromagnetic heating controller 2, coil 3, heat-insulation layer
The specific embodiment
As shown in Figure 1, a kind of electromagnetic heating device of injection machine is made of several electromagnetic heating controllers 1, coil 2, heat-insulation layer 3, coil 2 is wrapped on the heat-insulation layer 3, electromagnetic heating controller 1 is connected on the coil 2, and described electromagnetic heating controller 1 is 4, and coil 2 is resistant to elevated temperatures coil.
Heat-insulation layer 3 is wrapped in external of injection-tube, and electromagnetic heating controller 1 produces high-frequency ac current, and resistant to elevated temperatures coil 2 is wrapped on the heat-insulation layer 3 electromagnetic heating controller 1 electric energy is exported, and makes the injection body produce eddy-current heating by electromagnetic induction principle.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
