A die thermometer is arranged on the die. The die cavity comprised of the movable die and the static die has five symmetrically arranged deep-long wing sheet groove for formed thin-wall wing sheets, two rows of copper pipe supporting and positioning clamps are horizontally arranged inside the static die cavity, and the copper pipe supporting and positioning clamps are fixing connected with the static die. The spray port is arranged on the head of the die cavity, and an exhaust port is arranged at the back of the die cavity. Composite copper-magnesium-alloy column-wing-type convection radiators made from the utility model are featured with small weight, high strength, good decoration effect, low cost, high radiation capacity, even heat flow, dry-hot-free, good corrosion resistance and good endurance. The embedded pipe inserts and the main part are cast simultaneously, so the embedded pipe inserts and the main part are reliably connected, and the service life is long.
Description
Affiliated technical field
The utility model relates to the die casting technical field, especially a kind of magnesium alloy-copper die casting combined column aerofoil profile convector radiator die casting.
Background technology
The general heating system that adopts radiator, boiler body, pipe-line system and high-temperature-hot-water heating agent (or steam) to constitute in the most of area of northern China solves people's heating problem, antagonism severe cold.As the radiator of heating system end equipment, traditional have cast-iron radiator, a steel radiator.As everyone knows, cast-iron radiator heaviness, presentation quality are poor, so people adopt steel radiator to replace cast-iron radiator.But steel radiator antioxygen corrosive power is poor.Because China urban heating system is mainly based on central heating, a lot of heating system designs have been selected normal-pressure boiler direct heating for use or have been selected the open type expansion tank for use or selected the constant pressure pump level pressure for use and automatic drainage system etc., this non-enclosed heating system constantly discharges water and moisturizing, makes ducted oxygen content severe overweight; In addition because the management existing problems, parts such as valve in bad repair with age or that select for use are defective or appearance lack of standardization is installed leaks in a large number, the hot water of missing has only by replenishing cold water realizes balance, and this has more increased ducted oxygen content, so steel radiator is shorter service life.For remedying the deficiency of steel radiator antioxygen corrosive power difference, people adopt and are coated with the passive mode of chemical preservation coating at the steel radiator inner chamber, but can't detect coated thickness of coating and uniformity, and therefore coated quality is difficult to guarantee.Because aluminium has stronger antioxygen corrosive power, therefore people adopt Aluminium Radiator again a few years ago, but aluminium alkali resistance corrosive power is very poor, only is applicable to the heating water quality of PH=5～8.5, is not suitable for the current widely used open type boiler direct supply system of China (PH=10～12).Copper is a kind of antioxygen corrosive power and all very strong material of alkali resistance corrosive power, but China's copper resource scarcity costs an arm and a leg, and copper proportion is bigger, and copper radiator weight is heavier.China's magnesium resource is abundant, magnesium alloy is in light weight, intensity good, good decorative property, if can adopt magnesium alloy to make radiator and embedded copper pipe, then the antioxygen corrosive power of radiator and alkali resistance corrosive power are all very strong, cost of manufacture is low again simultaneously, and ornamental good again.How with copper pipe and magnesium alloy in conjunction with firmly being the key of making this radiator, adopting die casting compound is in conjunction with firm effective ways with two kinds of materials.But because copper is different with the magnesium alloy thermal coefficient of expansion, cause being coated on the magnesium alloy and the copper pipe disengagement of copper pipe surface in press casting procedure and the use because of expanding with heat and contract with cold, because ducted hot water or steam have certain pressure, heating especially for skyscraper, in case magnesium alloy combines insecure words with copper, quick-fried strong phenomenon occurs easily and cause radiator to damage, have an accident.
Summary of the invention
In order to overcome the deficiency of existing technology, the purpose of this utility model provides a kind of magnesium alloy and combines magnesium alloy-copper die casting combined column aerofoil profile convector radiator die casting reliably with copper.
Technology and case that its technical problem that solves the utility model adopts are: a kind of magnesium alloy-copper die casting combined column aerofoil profile convector radiator die casting, be dark chamber die casting, have and lump together the mould main body that the dynamic model that forms mold cavity and quiet mould are formed, be fixed with die heater on the mould main body, the mold cavity of dynamic model and quiet mould has the profound wing tank of five symmetrically arranged forming thin-walled fins respectively, be horizontally disposed with two row's copper pipes in the mold cavity of quiet mould and supported the location clip, copper pipe supports the location clip fixedlys connected with quiet mould, jet is arranged on the mold cavity head end, and the mold cavity rear end is provided with bleeding point.
Be positioning supports copper pipe preferably, prevent to cause the copper pipe of product not firm with surperficial magnesium alloy combination because of the thermal coefficient of expansion of copper and magnesium alloy is different, every row's copper pipe supports the setting of locating copper pipe support location clip in the clip and is spaced apart 40mm～120mm in the described mold cavity, and copper pipe supports location clip hem width 1.5mm～3mm.The magnesium alloy of the copper pipe surface of the product after moulding has the gap like this, copper pipe and magnesium alloy be in conjunction with reliable, to such an extent as to also can not occur the phenomenon that causes copper pipe and surperficial magnesium alloy to come off in conjunction with unreliable surperficial magnesium alloy because of the thermal coefficient of expansion of copper and magnesium alloy is different in the radiator use.
The beneficial effects of the utility model are, utilize the magnesium alloy-copper die casting combined column aerofoil profile convector radiator of the utility model preparation, and body is a magnesium alloy, and it is in light weight, and intensity is good, good decorative property, and cost is low; This body profile is the column type of band fin, make product all have three primary conditions of high heat dispersion, instant heating conduction, heat radiation and cross-ventilation, the other types radiator only possesses heat conduction and heat radiation, in thermal energy exchange, convection current is the effective means that improves thermal efficiency, can improve heat and imitate more than 20%, and hot-fluid is even, does not have scorching phenomenon; The built-in water passage inserts is a copper material, its corrosion resistance and good, intensity height, long service life; Magnesium alloy is moulding in die casting under high-temperature liquid state, and material density is big, and the surface does not have welding processing stand face, and is sturdy and durable; Built-in water passage inserts and the embedding of main body through pressure casting bag, body and built-in water passage inserts are in conjunction with reliable, to such an extent as to can in use not occur because of the magnesium alloy on different copper pipes that cause of the thermal coefficient of expansion of copper and magnesium alloy and surface in conjunction with unreliable surperficial magnesium alloy come off, the built-in water passage inserts is quick-fried strong, thereby cause radiator to damage, have an accident.
