Injection molding machine electromagnetic induction heating soaking device

Abstract

The invention discloses an injection molding machine electromagnetic induction heating soaking device and relates to the technical field of heating. The injection molding machine electromagnetic induction heating soaking device comprises an electromagnetic heating cylinder and an electromagnetic heating controller. The electromagnetic heating cylinder comprises an inner layer material cylinder, middle layer insulation cotton and an outer layer wound high-temperature wire electromagnetic coil. The surface of the insulation cotton is fixedly wrapped with a high-temperature-resistant cloth. Effective gaps are kept between wound wires of the high-temperature wire electromagnetic coil. The electromagnetic heating controller has matched capacitance inductance and current range. The high-temperature wire electromagnetic coil comprises two or more coil sets. All the coil sets are tightly wound on the insulation cotton and are separated from each another. Every two adjacent coil sets adopt a rewinding mode, namely the high-temperature wire electromagnetic coil is opposite in winding direction, and generated electromagnetism directions are opposite. The injection molding machine electromagnetic induction heating soaking device provided by the invention is even in temperature distribution, stable in product quality, long in device service life and good in energy saving effect.

Description

technical field [0001] The invention belongs to the technical field of heating, in particular to an electromagnetic induction heating homogenizing device for an injection molding machine. Background technique [0002] In the traditional heating industry, resistance wire and quartz heating methods are commonly used, but this traditional heating method has relatively low thermal efficiency. Resistance wire and quartz mainly rely on electricity to generate heat by themselves and then transfer the heat to the barrel. , so as to achieve the effect of heating objects, the heat utilization rate of this heating effect is only about 50%, and the other 50% of the heat is dissipated into the air, and the power loss of all traditional resistance wire heating methods is as high as 50%. . And through electromagnetic induction heating, the magnetic field is generated by the current, so that the iron metal pipe itself heats up, and the heat insulation material is added to prevent the heat ...

AI Technical Summary

Problems solved by technology

Resistance wire heating has problems such as large heat loss, rising ambient temperature, short service life, and large maintenance, but its biggest advantage is uniform temperature distribution; relatively speaking, electromagnetic induction heating has good energy-saving effects, good environmental protection effects, and long service life. Long and other advantages, but the temperature distribution is uneven in the electromagnetic induction heating p
