The utility model relates to casting field, is specifically related to a kind of complicated casting system die casting.
Background technology
In foundry industry, die casting makes a kind of common casting mould.Die casting is a kind of casting mould of casting liquid forging, a kind of technique completed on special die casting die forging machine; Its basic craft course is: the first low speed of molten metal or high-speed casting fill in the die cavity of type progressive die tool, and along with the cooling procedure pressurization forging of molten metal.In press casting procedure, in order in the process of mold cavity by filled with metal by mold cavity and the molten metal gas that solidifies precipitation discharge mould as much as possible, reduce and prevent defects such as producing pore in die casting, be not fully filled, needing to arrange exhaust structure on die casting.
Exhaust structure on current die casting is generally the air discharge duct be arranged on mold parting surface, this exhaust structure run into cavity structure comparatively complicated situation time, due to the injection of molten metal, air is compressed to the position such as cavity bottom, corner, gas cannot be overflowed, and easily causes to fill discontented or to generate pore etc. bad.Such as, China Patent Publication No. CN203764928U, publication date on August 13rd, 2014, the name of innovation and creation is called a kind of aluminium alloy compression casting exhaust structure and die casting, and exhaust structure comprises at least one air discharge duct, and the air discharge duct degree of depth is not less than 0.3mm.The exhaust structure of this application case aluminum alloy die-casting die is the air discharge duct be arranged on die joint, there is the injection due to molten metal equally in it, air is compressed to the position such as cavity bottom, corner, and gas cannot be overflowed, and easily causes and fills the bad problem such as discontented or generation pore.
Utility model content
The purpose of this utility model be in order to overcome in prior art run into cavity structure comparatively complicated situation time, due to the injection of molten metal, gas is compressed to the position such as cavity bottom, corner, gas cannot be overflowed, easily cause and fill the bad problem such as discontented or generation pore, there is provided one can effectively solve run into cavity structure comparatively complicated situation time, due to the injection of molten metal, gas is compressed to the position such as cavity bottom, corner, gas cannot be overflowed, and easily causes the complicated casting system die casting of filling the bad problem such as discontented or generation pore.
The technical solution of the utility model is:
A kind of complicated casting system die casting, comprises die shoe, the patrix being arranged on the counterdie on die shoe and being positioned at above counterdie, cooling water flow conduits is provided with in described patrix, described counterdie is provided with oblique pulled core structure, and counterdie die joint is provided with air discharge duct, is provided with lower cooling water flow conduits in counterdie; Some lower exhaust passages be connected with counterdie die cavity are provided with on described counterdie lateral surface, near counterdie cavity bottom, on counterdie sidewall, be positioned at the peripheral lower annular cooling cavities be respectively equipped with around lower exhaust passage in each lower exhaust passage, and each lower annular cooling cavities is near counterdie lateral surface, described lower cooling water flow conduits is communicated with each lower annular cooling cavities successively.
This programme is provided with some lower exhaust passages be connected with counterdie die cavity on counterdie lateral surface, near counterdie cavity bottom, thus in the process that molten metal injects, the gas being compressed to the position such as cavity bottom, corner can be discharged by lower exhaust passage, effective improvement cannot be overflowed because of gas, easily causes and fills discontented or generate the bad problem such as pore.
On the other hand, because periphery, lower exhaust passage is respectively equipped with the lower annular cooling cavities around lower exhaust passage, each lower annular cooling cavities is near counterdie lateral surface, and lower cooling water flow conduits is communicated with each lower annular cooling cavities successively; Like this in press casting procedure, when in the process that molten metal flows outward along lower exhaust passage under pressure, due to the cooling effect of cooling water, time near metal liquid stream to lower annular cooling cavities, the rapid cooled and solidified of molten metal, thus realize in press casting procedure, under the prerequisite of being discharged by lower exhaust passage by the gas being compressed to the position such as cavity bottom, corner, effectively avoid molten metal under pressure along the overflow outward of lower exhaust passage.
As preferably, each lower exhaust passage is positioned at the same side of counterdie die cavity, and each lower annular cooling cavities is near the water inlet of lower cooling water flow conduits, and away from the delivery port of lower cooling water flow conduits.
Because each lower annular cooling cavities is near the water inlet of lower cooling water flow conduits, and away from the delivery port of lower cooling water flow conduits; After descending the cooling water in cooling water flow conduits to be flowed into by the water inlet of lower cooling water flow conduits like this, by first flowing through each lower annular cooling cavities, then in its remaining cooling water flow conduits, counterdie is cooled; Thus can effectively improve the cooling effect of cooling water flow when lower annular cooling cavities further, effectively avoid molten metal further under pressure along the overflow outward of lower exhaust passage.
As preferably, oblique pulled core structure comprises core, be arranged on counterdie base place, and the pilot hole extended obliquely, slidably be arranged on the slide block in pilot hole and the pneumatic cylinder be fixed on counterdie or hydraulic cylinder, described pilot hole is connected with counterdie die cavity, and one end of described core is connected with slide block, the piston rod of described pneumatic cylinder or hydraulic cylinder is connected with slide block, and the piston rod of pneumatic cylinder or hydraulic cylinder parallels with pilot hole.The oblique pulled core structure of this programme not only can mould casting structure, and be arranged on counterdie base place due to pilot hole, scavenging action can also be played in gap between such core and pilot hole, is discharged by the gas being compressed to the position such as cavity bottom, corner further.
As preferably, on counterdie, the port that is positioned at pilot hole is provided with the bracing frame extended obliquely, and described pneumatic cylinder or hydraulic cylinder are arranged on bracing frame.
As preferably, air discharge duct is made up of the left bank air drain be positioned on the left of counterdie die cavity and the right air discharge duct be positioned on the right side of counterdie die cavity, described left bank air drain by be arranged in order distribution first, second, third, fourth and the 5th left bank air drain form, described right air discharge duct is made up of the first, second, third, fourth, the 5th and the 6th right air discharge duct being arranged in order distribution.The vent groove configuration of this programme, can improve the exhaust capacity of mould further.
As preferably, lower exhaust passage is horizontally disposed with.
The beneficial effects of the utility model are: can effectively solve run into cavity structure comparatively complicated situation time, due to the injection of molten metal, gas is compressed to the position such as cavity bottom, corner, and gas cannot be overflowed, and easily causes and fills the bad problem such as discontented or generation pore.
