Background technology
Die casting machine is exactly under pressure the equipment cooling down molding in molten metal bath injection to mould, obtains a series of industry foundry machinery of solid metal foundry goods after die sinking.Die casting machine is generally divided into hot press chamber die casting machine and cold pressing chamber die casting machine, and hot press chamber die casting machine is the same with the clamping of cold pressing chamber die casting machine, and it is distinctive in that injection, casting mechanism are different.The pressure chamber of hot press chamber die casting machine and smelting furnace are closely linked to be an entirety, and the pressure chamber of cold pressing chamber die casting machine and smelting furnace are what to separate.Along with the continuous expansion of domestic existing kirsite industry, the quantity of the fusing stove that zinc alloy casting uses also constantly increases.At present, traditional zinc alloy smelting furnace has oil burner, coal furnace and electric furnace, but these zinc alloy smelting furnaces all have its respective defect.Such as, exhaust emission environment can be produced after oil burner costs rather expensive and fuel oil burning；Although the cost of coal furnace is cheap, but fire coal can produce waste gas in combustion equally and cause environmental pollution, and the temperature in coal furnace in use stove controls inaccuracy；Electric furnace transfers heat in the melting pot filling kirsite by air after substantially adopting electrothermal wire heating, although its mode of heating will not to environment, but it is to pass through air transfers heat, this can allow heat energy cause consumption in transmittance process unavoidably, the burn-off rate of alloy is slow, increasing the consumption of electric energy, and the service life of thermoelectric wire is short, the use cost of the electric furnace made is bigger.For this, China Patent No.: 201020504728.5 openly know clearly a kind of directly-heated type zinc alloy smelting furnace, including furnace shell, melting pot, temperature sensor and electric-controlled box, heat-insulation layer it is provided with between furnace shell and melting pot, one end of temperature sensor and the temperature measuring point cantact on melting pot, the other end electrically connects with electric-controlled box, is provided with electric heating tube in the chamber of melting pot, and the electric connecting terminal of electric heating tube electrically connects with electric-controlled box.Adopt electric heating tube directly to contact with kirsite, enhance heat transference efficiency, reduce the loss of electric energy；But the insulation aspect of body of heater still adopts common practice, namely it is incubated at insulation materials such as one layer of asbestos of body of heater outer cladding；Temperature in body of heater still transfer spreading is gone out, body of heater heat slowly spreads transmission and consumes either directly through adiabator layer, consumes electric energy too high, and heat insulation effect is poor, especially for the zinc alloy diecasting machine of medium-and-large-sized number, its power consumption still remains high, and the engine power of its driving requires higher.
Summary of the invention
Therefore, for above-mentioned problem, the present invention proposes a kind of simple in construction, be effectively improved furnace insulation effect, save a large amount of electric energy, reduce the zinc alloy diecasting machine of power strength needed for medium-and-large-sized board.
For solving this technical problem, the present invention takes below scheme: a kind of zinc alloy diecasting machine, including board, the holding furnace being located on board and the electric heater unit be located in holding furnace cavity volume, the body of heater of described holding furnace includes internal protecting wall, heat-insulation layer and outer furnace wall, described internal protecting wall and outer furnace wall are connected with each other Guan Bi and constitute the outside framework of body of heater, and described heat-insulation layer is located at outer furnace wall inner surface and is provided with one layer of cavity between heat-insulation layer and internal protecting wall.
Further improving, between described heat-insulation layer and internal protecting wall, spacing distance is 1cm-8cm.
Further improving, described heat-insulation layer is asbestos layer or heat-preservation cotton layer.
Further improve, described electric heater unit includes electric heating tube, electric-controlled box and temperature sensor, described electric heating tube is located in holding furnace cavity volume, described temperature sensor is located on the internal protecting wall of body of heater, described temperature sensor is connected with electric-controlled box input, described electric-controlled box connects and controls electric heating tube, and the end that controls of described electric-controlled box is connected with the PLC outfan of board.
nullBy adopting preceding solution，The invention has the beneficial effects as follows: by the furnace binding of holding furnace is carried out new design，Namely cavity is set between the internal protecting wall of body of heater and heat-insulation layer，Make emptying between heat-insulation layer and internal protecting wall，The heat making body of heater cannot carry out direct transfer spreading heat by heat-insulation layer，Consumption of calorie is few，Peripheral at internal protecting wall by spacer insulating layer air-coating again，Heat is made to preserve efficiency high，The holding furnace making the die casting machine of the present invention consumes electricity and reduces 2-3 times compared with the holding furnace of prior art，Generated output simultaneously for medium-and-large-sized zinc alloy diecasting machine also has very big improvement，As original need 24 kilowatts start electric heater unit to be heated，Nowadays only need 12 kilowatts and can supply enough electrical heat energies，The present invention has simple in construction、Production cost is low、It is effectively improved furnace insulation effect、Save a large amount of electric energy、Reduce the power strength needed for medium-and-large-sized board、The remarkable results such as energy-conserving and environment-protective，Can wide popularization and application.
