Abstract
The invention discloses an induction heater for an injection machine, wherein several segments of coils are winded outside the head; a hoop is disposed between segments of the coils respectively; a change-over switch is fixed on each hoop respectively; each change-over switch is connected with the front-end and the back-end taps of an adjacent coil; an insulating layer and a rigid air duct uniformly disposed in axial direction are disposed between the coils and the head. The induction heater adopts an electromagnetic induction heating mode, which does not require preheating, greatly decreases the energy consumption, and improves the working efficiency. The heating coils are segmented; by allowing the change-over switch to select different taps so as to change the number of turns for each segment, the voltage of each segment of coil is adjusted, and the temperature of each segment is adjustable; the application is more convenient and flexible; the insulating layer is disposed, so the heat dissipation of the head to surrounding environment is reduced; the ambient temperature is decreased; the production security is improved; the head is not exposed in the air, so the head is not easy to be oxidized, and the service life is prolonged.
Description
Technical field
The present invention relates to induction heater, be specifically related to be used for the induction heater of injection machine.
Background technology
The injection machine heater is the heating of plastic particle; Make it reach molten state; And molten plastic applied high pressure; Make its ejaculation and be full of mold cavity, can one-shot forming complex contour, size accurately or have the dense plastic products of quality of metal insert, be widely used in every field such as national defence, electromechanics, automobile, packing.The tubulose head of existing injection machine heater needs very long preheating time through the resistance wire heating, has wasted electric energy greatly.Heat makes production environment be in the condition of high temperature to the external environment transmission, and workman's operating environment is abominable.Head is exposed to oxidation easily in the air, and resistance wire is in the high-temperature oxydation state, and service life is short, needs often to change.
Summary of the invention
The purpose of this invention is to provide a kind of energy efficient, make things convenient for temperature control, increase work efficiency, strengthen production security, the induction heater that is used for injection machine easy for installation.
For reaching above-mentioned purpose, the induction heater that is used for injection machine disclosed by the invention comprises the tubulose head; Be around with the plurality of sections coil at head, head, the end of every section coil are established tap, install anchor ear between each section coil respectively; Fixing change-over switch respectively on each anchor ear, each change-over switch links to each other with the tap of adjacent windings, is respectively equipped with thermometer hole on each anchor ear; Between coil and head, heat-insulation layer is arranged, be evenly equipped with the rigidity air channel between heat-insulation layer and the head vertically, an end in rigidity air channel is installed as the copper pipe anchor ear of concentrating air intake; The copper pipe anchor ear leaves fresh air inlet respectively towards corresponding each air channel, the side in rigidity air channel, and each fresh air inlet is corresponding with each rigidity air channel one end to link to each other, the end sealing of copper pipe anchor ear; The other end is an air inlet, and the other end in rigidity air channel is an air outlet.
The present invention compared with prior art has the following advantages: induction heater of the present invention does not need preheating through electromagnetic induction heating, has significantly reduced energy consumption, increases work efficiency.Heater coil segmentation and regionalization territory, every section coil is established tap, selects different taps to change every section coil turn through change-over switch, regulates the voltage of every section coil; Realize that every section temperature is adjustable, use more convenient flexibly, the insulation layer is set; Reduced the heat radiation of head, reduced environment temperature, improved production security surrounding environment; Head is not exposed in the air, is difficult for oxidizedly, has prolonged service life; The insulation heat insulation layer is established and is regulated the air channel, can control temperature effectively, satisfies the production demand better.
