Description

Mold preheating device
Technical field
The present invention relates to a kind of mold preheating devices.
Background technique
When using die casting or forging workpiece, since mold temperature is low, casting melt temperature is very high, it is easy to cause into The defects of type difficulty, mucous membrane, casting crack.Secondly as low temperature mold changes too greatly with high temperature casting melt, cold and hot stress is very Greatly, it is easy to cause burn failure, under serious situation, cause mold to burst, therefore, mold must preheat before, make mould Certain temperature is reached when having working condition.
It is different according to the heating means of preheating, electric heating forged material can be divided into, rock gas heats, die heater oil adds Heat.
Electric heating forged material: heating iron plate or round steel mainly by heat-generating pipe, is directly placed on mould round steel or tappasaki are red On tool, advantage is easy to operate, quick heating, high with the iron plate contact position temperature of burning red the disadvantage is that use cost is high, mold it is hard Degree changes, and cold and hot stress is very big, it is easy to burn failure is caused, so that the service life of mold is influenced, the precision of mold It is impossible to ensure that.
Rock gas heating: a kind of now widely used mode is suitable for different mold shapes.Heater is by pipe system At having many apertures, spray gas, the adjustable air valve of firepower size is realized.Cleanliness without any pollution, can local heating.Disadvantage It is to be controlled by people, is easy to burn out mold, different mold materials can not accurate set temperature.
The heating of die heater oil: full heating process is completed in temperature control box, although homogeneous heating, temperature is adjusted using intelligence control System, temperature-controlled precision are high, can meet the strict demand of high technology standard, but mold it is preheated after must be from the temperature control box of die heater Interior taking-up mold could use, and since temperature control box and preheated mold temperature are high, take out mold and be easy scald operator, Zhi Nengchi Continuous property is inconvenient to use using operation.Secondly, mold heat leakage is fast while taking out mold, mold when causing to cast or forge Temperature not up to requires, it has not been convenient to.Summary of the invention
That the technical problem to be solved in the present invention is to provide a kind of preheated mold temperature is constant, can be carried out continuously operation, use Convenient mold preheating device.
In order to solve the above-mentioned technical problem, mold preheating device of the invention, including heat transfer frame and electric heater, the heat transfer Frame is coated on outside electric heater, and the heat that the electric heater distributes is transmitted to mold by the frame that conducts heat.
The shape of the heat transfer frame is rectangle.
The heat transfer frame is made of copper material or aluminum material.
The heat transfer frame by two pieces or three pieces or four pieces or five pieces of board groups at;Described two pieces or three pieces or four pieces or five blocks of plates Between adjacent surface be equipped with mutually matched card slot, for putting electric heater.
Adjacent surface between described two pieces or three pieces or four pieces or five blocks of plates is equipped with mutually matched clamping groove, clamping block, Two adjacent panels between described two pieces or three pieces or four pieces or five blocks of plates are fixedly connected by clamping groove, clamping block.
The heat transfer frame is poured by molten metal.
The electric heater is electrothermal tube.
The electric heater and power supply line junction are equipped with spark plug porcelain insulator, leak electricity for preventing.
Temperature probe is equipped in the heat transfer frame, the power supply of the temperature probe is electrically connected with the power switch of electric heater, is used It is controlled in the power switch of electric heater by temperature probe.
It further include frame, the shape of the frame and heat transfer frame is adapted;The heat transfer is placed in frame and heat transfer frame Top surface and frame top surface are in same level.
The frame is surrounded by both side plate;The framework upper inner wall is equipped with convex edge;The convex edge is equipped with cover board, The pressure of heat transfer top of support is acted on for dispersing carrying.
Using structure of the invention, since including heat transfer frame and electric heater, heat transfer frame is coated on outside electric heater, and electric heater dissipates The heat of hair is transmitted to mold by the frame that conducts heat.In use, opening electric heater power switch, heat is passed through biography by electric heater fever Hot frame is transmitted to mold, when mold reaches certain temperature, without removing mold, is directly cast or is forged on mold Operation, is not easy to scald operator, can be carried out continuously and operate with, preheated mold temperature is constant, and mold is hardly damaged, and uses the longevity Life length, it is easy to operate, it is easy to use.
Due to heat transfer frame by two pieces or three pieces or four pieces or five pieces of board groups between two pieces or three pieces or four pieces or five blocks of plates Adjacent surface be equipped with mutually matched card slot, for putting electric heater, process simpler, production cost is lower, using more It is convenient, it operates simpler.
It since electric heater and power supply line junction are equipped with spark plug porcelain insulator, leaks electricity for preventing, the service life is longer, operation More convenient, working efficiency is higher.
Due to being equipped with temperature probe in heat transfer frame, the power supply of the temperature probe is electrically connected with the power switch of electric heater, is used It being controlled in the power switch of electric heater by temperature probe, can faster and more accurately control the temperature of mold, working efficiency is higher, Operation is simpler, using more convenient.
Again due to further including frame, the shape of frame and heat transfer frame is adaptable, and heat transfer is placed in frame and frame top of conducting heat Face and frame top surface are in same level, and frame dispersion carrying acts on the pressure of heat transfer top of support, so that service life is more Long, work efficiency is high, easy to operate, easy to use.
It is surrounded again due to frame by both side plate, framework upper inner wall is equipped with convex edge, and convex edge is equipped with cover board, for dividing Scattered carrying acts on the pressure of heat transfer top of support, and the service life is longer, and work efficiency is high, easy to operate, easy to use.
