Description
Technical field
The utility model belongs to the die casting field, relates in particular to a kind of die casting cooling device.
Background technology
In the die casting production process, the temperature of mould is to influence a good key factor of formed product, local high temperature or low temperature can have a strong impact on formed product and die life, though mold temperature can not reach absolute equilibrium in actual production, but by correct design to mould structure, cooperate efficient, rational cooling system, each regional temperature of mould can be controlled.Owing to the production environment more abominable in the die casting production process and the particularity of die cast metal, mould needs to bear repeatedly quenching and shock heating nearly 300 ℃ temperature difference at short notice, can produce great alternating thermal stress, very easily cause the cracking of mould, cause scrapping of mold materials; Simultaneously, owing to metal mold die casting need be poured into a mould, and in mould, be cooled to the die sinking of metal subsolidus uniform temperature ability when metal liquid, thereby the cooling effectiveness of mould directly influences the efficient that die casting is produced.
In sum, reasonably cooling system is adjusted most important for mould structure and technology.The die casting cooling system of Cai Yonging mainly contained following several mode in the past:
(1) air-cooled: as shown in Figure 1, compressed air inserts from the outside, and the compressed air channel 912 in die 911 imports and needs the cooling position, and at the mould closure state, slide block 913 closed channel mouths make compressed air not enter mould inside; When die sinking, slide block 913 is opened compressed air channel 912, cooling wafer shape core 914.Its shortcoming is owing to need offer compressed air channel specially, and need offer inflatable mouth, and is bigger for non-slide block position limitation that can't be closed, and exists die casting production apoplexy cold efficiency lower, and wind energy such as can not recycle at defective.
(2) heat pipe cooling: heat pipe is the sealed metal tube that heat transfer medium (normally water) is housed, and inside pipe wall is covered with capillary layer.Its operation principle is as shown in Figure 2: heat transfer medium evaporates after the temperature end 921 (being evaporating area) of heat pipe absorbs heat, and steam 923 is got back to temperature end 921 by the capillary layer 924 in managing in low-temperature end 922 (being condensing zone) condensation after the condensation again.The general vertical setting of heat pipe, low-temperature end 922 heat exchange efficiency when top is the highest, and low-temperature end 922 generally can adopt water-cooled or air-cooled.Its shortcoming is: the position of needs emphasis cooling in heat energy-saving position of suitable cooling die (position in the instant heating quantity set) and the die only, be not suitable for large-scale cooling, and because it need cooperate mould water-cooled or air-cooled use, and manufacturing cost is higher, so less use.
(3) die heater cooling: though adopt the die heater cooling effective, die heater costs an arm and a leg, and needs to be equipped with special-purpose interface, also need offer corresponding oil circuit on mould, and is very uneconomical.
(4) water cooling: water circulation cooling is the most widely used a kind of type of cooling in the existing compression mod, its operation principle is to utilize the specific heat capacity of specific heat of water appearance greater than steel, inner by water being imported mold cavity through after the circulation, take the mould inside heat out of the mould outside, recycling by importing mould after a series of equipment cooling again again.As shown in Figure 3: in mold cavity, get out a rectangle loop in advance, and utilize plug 93 1 will need the position sealing of sealing, outside water enters by water inlet 932, flows out from delivery port 933 after the rectangle circuit cycle, and the heat of taking away mold cavity makes its cooling.Though it has efficient height, easy to control, advantage that cost is low and capable of circulation; But following shortcoming is arranged: need dig waterway channel in mold cavity, for large and medium-sized die casting, because it is complex-shaped, molded surface just rises and falls, and is difficult to arrange too much closed circuit, interferes otherwise can produce with thimble, pin etc.
The utility model content
Technical problem to be solved in the utility model is to provide that a kind of cost is low, efficient is high, can controls the die casting cooling device of each regional temperature of mould by demand.
The utility model is to realize like this, a kind of die casting cooling device, comprise a device for cooling and water inlet assembly that is communicated with described some device for cooling respectively and water outlet assembly, described some device for cooling comprises a little cold outer tube and is sheathed on the cold interior pipe of the interior point of the cold outer tube of described point, pipe was communicated with described water inlet assembly in described point was cold, and cold outer tube of described point and the gap of putting between the cold interior pipe are communicated with described water outlet assembly.
The utility model carries out the subregion cooling by the mode of a cooling to each zone of mould, can control each regional temperature in the mould by demand, thereby guarantee the moulding of die-cast product significant points and the compactness of interior tissue thereof, be highly suitable for the cooling system of large die-casting mould and complicated die casting, have that cost is low, efficient is high, volume is little, be convenient to advantages such as dismounting and cleaning.
