The sketch map of the acceleration channels exhaust structure that Fig. 2 provides for the embodiment of the invention.
The specific embodiment
Technical scheme is for a better understanding of the present invention described embodiment provided by the invention in detail below in conjunction with accompanying drawing.
The embodiment of the invention provides a kind of zinc-aluminum-magnesium alloy die cast mould, and is as depicted in figs. 1 and 2, comprising: preceding mould bases 1 and back mould bases 14, and said preceding mould bases 1 is provided with front mould meat 2 and sprue bush 3; Said back mould bases 14 is provided with back mould meat 11 and divides flow cone 4; Also be provided with front mould temperature probe 5 and front mould electrical equipment box 7 before said on the mould bases 1, also be provided with back mould temperature probe 13 and back mould electrical equipment box 10 on the mould bases 14 of said back, wherein:
In the said front mould meat 2 front mould heat power supply device 6 is installed; In the said back mould meat 11 back mould heat power supply device 12 is installed; Said front mould heat power supply device 6 connects power controling box through front mould electrical equipment box 7 and is connected power controling box with back mould heat power supply device 12 through back mould electrical equipment box 10, and said back mould temperature probe 13 is connected said power controling box respectively with front mould temperature probe 5.
In other embodiment, on the foregoing description basis, further, parting line venting piece 8 before also being provided with on the said preceding mould bases 1 also is provided with back parting line venting piece 9 on the mould bases 14 of said back.
In other embodiment; On above-mentioned each embodiment basis; Further, said back mould meat 11 is provided with cross gate 17, and said cross gate 17 is provided with a plurality of pectination runners and comprises: be positioned at two middle pectination runners 16, be positioned at the pectination runner 15 of other positions etc.; And the turning-in respectively of the upper end of middle two pectination runners 16 is the centre position 18 of cross gate between the pectination runner 16 of two upper end turning-ins.Belong to liquid and be set to shunting through cast gate exactly and bore straight channel and arrive the pectination runner again to cross gate, the die cavity that gets into front mould meat, back mould meat formation at last becomes product.Two pectination runners 16 were owing to can guarantee to obtain the centre position 18 of the metal liquid of the highest temperature at cross gate in the middle of this mould can let; Just can guarantee under the uniform pressure state; The flow velocity in the centre position 18 of cross gate is higher than the position, both sides, thereby makes the smooth and easy discharge of gas.
In the above-described embodiments, the front mould heat power supply device passes through the electric energy self-heating with back mould heat power supply device;
Give front mould meat and back mould meat with the hot respectively conduction of said heating then;
Said front mould temperature probe, back mould temperature probe are measured the temperature of said front mould meat and back mould meat respectively;
And this temperature fed back to power controling box continue heating with control front mould heat power supply device and back mould heat power supply device, thereby front mould meat and back mould meat are reached need and be stationary temperature.
In the prior art, owing to alloy liquid solid rate under the occupied state changes mainly because high-temperature liquid metal produces heat exchange with mould meat in filling process change, solid rate reaches 0.3 part and just has been difficult to moulding generally speaking.Control mould through temperature control device in the embodiments of the invention; Thereby solid rate is lower than the solid rate that filler alloys allows when having guaranteed to fill; Guaranteed that die cast fills condition, mold temperature is remained to formed product before solid rate below 0.3, just can be with the forming parts of thin-walled.
Preceding parting line venting piece is to make things convenient for the gas in the die cavity to discharge with back parting line venting piece.The mould meat of high temperature has reduced solid rate, but has also heightened flowability, and the exhaust structure that provides in the prior art will inevitably make molten metal along with exhaust duct is discharged, like this will pressure release, and final product also finally can not get elevated pressures and shrinkage porosite.Before and after the parting line venting piece belong to the Quench type, molten metal one solidifies to Quench here, goes out never again.
It can be compressed then and to hide that product is inner forms pore if the thicker product die cavity of wall thickness has gas, but ultra-thin-wall does not have the Zang Na space, in case there is gas not get rid of, what form on the part of moulding no longer is pore but perforation.Therefore the runner that is beneficial to air scavenge also is the most important thing of mould of the present invention.Because the occupied state that tapered runner forms must be that the two ends flow velocity is faster than the centre; Taper pectination runner is no exception; Reason is that metal liquid stream is to runner under the slow pressure condition, and the die casting machine speed-raising of the full back of runner filling is high pressure, but owing to the molten metal of contact die cavity of the prior art exchanges prior to mold hot; This money paid for shares belongs to liquid temp must be lower than the back molten metal; Its flowability must be lower than other so, in the middle of therefore traditional taper pectination runner meeting both sides filling speed is higher than, gas will be enclosed in middle and go out not go so.Preceding parting line venting piece among the present invention is the acceleration channels exhaust technique with back parting line venting piece; Two pectination branch flow passages turning wherein and reducing and form big resistance; The molten metal that straight channel arrives has earlier guaranteed that middle branch flow passage is assigned to molten metal at last, thereby has obtained being higher than the liquid of other position temperature because be obstructed and must flow to other position earlier here; The high-temp liquid flowability is best, runs also the most soon under the same pressure state.Gas so must be discharged.Guaranteed that the flow velocity in the middle of the runner was higher than both sides when alloy was filled, from inside to outside, guaranteed to fill not and can arrange not go out or exhaust influences filling speed slowly when guaranteeing the discharge of gas because of gas.
Thereby obtain qualified products such as forming part.Reach more than 95% through the overtesting yield rate.
More than a kind of zinc-aluminum-magnesium alloy die cast mould that the embodiment of the invention provided and the method for processing parts have been carried out detailed introduction; For one of ordinary skill in the art; Thought according to the embodiment of the invention; The part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as limitation of the present invention.
