According to the mould preheating device, operation and usage can be continuously performed, the temperature of the preheated mould is constant, the mould is not prone to being damaged, the service life is long, operation is easy, and use is convenient.
Description
Technical field
The present invention relates to a kind of mould and die preheating device.
Background technology
When using die casting or forging workpiece, because mold temperature is low, casting melt temperature is very high, be easy to cause the defects such as difficult forming, mucous membrane, casting crack.Secondly, cast liquation due to low temperature mould and high temperature and change too greatly, cold and hot stress is very large, is easy to cause burn failure, when serious, causes mould to burst, and therefore, necessary preheating before mould uses, makes to arrive uniform temperature during mold work state.
Different according to the heating means of preheating, the heating of electric heating forged material, rock gas, the heating of die heater oil can be divided into.
Electric heating forged material: mainly add hot iron plate or round steel by heat-generating pipe, directly round steel or tappasaki is red is placed on mould, advantage is easy to operate, quick heating, and shortcoming is that use cost is high, red iron plate contact position temperature is high with burning, the hardness of mould changes, and cold and hot stress is very large, is easy to cause burn failure, thus affecting the mold use life-span, the precision of mould can not ensure.
Rock gas heats: now widely used a kind of mode, is applicable to different mold shape.Heater is made up of pipe, has a lot of aperture, and ejection gas, firepower size can realize by adjusting air valve.Cleanliness without any pollution, can localized heating.Shortcoming controls by people, and easily burn out mould, different mold materials can not accurate design temperature.
Die heater oil heating: full heating process completes in temperature control box, although homogeneous heating, temperature regulates and adopts Based Intelligent Control, temperature-controlled precision is high, can meet the strict demand of high technology standard, but mould and die preheating good after must take out mould in the temperature control box of die heater and could use, due to temperature control box and preheated mold temperature high, take out mould and easily scald operating personnel, continuation can only use operation, use inconvenience.Next, while taking out mould, mold hot is scattered and disappeared fast, and when causing casting or forge, mold temperature does not reach requirement, inconvenient.

Described heat transfer frame is poured into a mould by molten metal and is formed.
Described electric heater is electrothermal tube.
Described electric heater and power line junction are provided with spark plug porcelain insulator, for preventing electric leakage.
Be provided with temperature probe in described heat transfer frame, the power supply of this temperature probe is electrically connected with the mains switch of electric heater, and the mains switch for electric heater is controlled by temperature probe.
Also comprise framework, described framework adapts with the shape of heat transfer frame; Described heat transfer is placed in framework and heat transfer top of support and framework end face are in same level.
Described framework is surrounded by biside plate and forms; Described framework upper inwall is provided with convex edge; Described convex edge is provided with cover plate, for disperseing to carry the pressure acting on heat transfer top of support.
Adopt structure of the present invention, owing to comprising heat transfer frame and electric heater, heat transfer frame is coated on outside electric heater, and the heat that electric heater distributes is transmitted to mould by heat transfer frame.During use, open electric heater power switch, heat is transmitted to mould by heat transfer frame by electric heater heating, when mould arrives certain temperature, without the need to mold removal, directly carry out casting or forging operation on mould, not easily scald operating personnel, operation can be carried out continuously use, preheated mold temperature constant, mould is not fragile, long service life, simple to operate, easy to use.
Due to heat transfer two pieces, frame or three pieces or four pieces or five pieces of plates compositions, the adjacent surface between two pieces or three pieces or four pieces or five blocks of plates is provided with the draw-in groove cooperatively interacted, for putting electric heater, processing is simpler, production cost is lower, uses more convenient, operates simpler.
Because electric heater and power line junction are provided with spark plug porcelain insulator, for preventing electric leakage, longer service life, it is more convenient to operate, and operating efficiency is higher.
Owing to being provided with temperature probe in heat transfer frame, the power supply of this temperature probe is electrically connected with the mains switch of electric heater, and the mains switch for electric heater is controlled by temperature probe, the temperature of mould can be controlled faster and more accurately, operating efficiency is higher, and operation is simpler, uses more convenient.
Again owing to also comprising framework, framework adapts with the shape of heat transfer frame, and heat transfer is placed in framework and heat transfer top of support and framework end face are in same level, framework dispersion carrying acts on the pressure of heat transfer top of support, and to make longer service life, operating efficiency is high, simple to operate, easy to use.
Form because framework is surrounded by biside plate again, framework upper inwall is provided with convex edge, and convex edge is provided with cover plate, and for disperseing to carry the pressure acting on heat transfer top of support, longer service life, operating efficiency is high, simple to operate, easy to use.
