Abstract
The utility model discloses an electrothermal ring, which is formed by thermal melting moulding on the injection moulding machine. The present electrothermal rings are entirely sealed type; once the heating material nichrome wire in the electrothermal ring is fused, the electrothermal ring is useless. The utility model is characterized in that a master and slave type structure is adopted. The master and slave type structure is composed of a master thermal conduction ring 1, a slave type heating block 2 and a fastening screw 3. Compared with the present the electrothermal ring of entirely sealed type structure, the utility model has the advantages of long service life of the master thermal conduction ring 1, convenient replacement of the slave type heating block 2, fast rise of temperature, electrical energy saving, and safe use.
Description
The utility model relates to and add a kind of Electrothermal ring that hot melt is moulded on injection molding machine.
The structure of conventional electric heating circle is the integral sealing formula, and its exothermic material is nickel filament, and in use, power consumption is big, temperature is also wayward, and nickel filament is easily aging, and the life-span is short.Owing to be integral sealing formula structure,, nickel filament just do not have value once blowing.
The purpose of this utility model is to overcome above-mentioned deficiency, the conventional electric heating coil structures is made improvements, and can reach and increase the service life economical with materials, automatic constant-temperature, safe and reliable, the effect of saves energy.
Below in conjunction with accompanying drawing, structure of the present utility model and purposes are made concrete description.
The utility model is made up of parent heat conduction circle 1, daughter heating piece 2 and holding screw 3.Daughter heating piece 2 is made up of nickel filament or PTC heating pottery 4, insulating material 5, foreskin 6 and contact conductor 7; Daughter heating piece 2 is to be fixed on the parent heat conduction circle 1 with flat head screw, thereby makes the integral body of a parent heat conduction circle 1 and an Electrothermal ring of many daughter heating piece 2 compositions; Exothermic material in the daughter heating piece 2 is nickel filament or PTC heating ceramic material, adopts the primary-secondary type assembly, and its purpose is to be convenient to change after exothermic material damages.Adopt serial or parallel connection between the contact conductor 7 on each daughter heating piece 2.
The utility model is compared with the Electrothermal ring of existing integral sealing formula structure, has parent heat conduction circle 1 long service life, and daughter heating piece 2 is convenient to change and can also reach quick heating, automatic constant-temperature, saves energy, safe and reliable advantage.
Most preferred embodiment of the present utility model:
Parent heat conduction circle 1, diameter are 10cm, and thickness is 5cm;
The volume of daughter heating piece 2 is: 5 * 1 * 0.5cm
3
And be evenly distributed on the parent heat conduction circle 1.
Claims (2)
1, a kind of Electrothermal ring is characterized in that it is made up of parent heat conduction circle 1, daughter heating piece 2 and holding screw 3.
2, a kind of Electrothermal ring according to claim 1 is characterized in that described daughter heating piece 2 is made up of nickel filament or PTC heating pottery 4, insulating material 5, foreskin 6 and contact conductor 7.
