Summary of the invention
The inventor believes that the those skilled in the art does not understand problem place (it is associated with employed machine barrel or pipeline in the metal-molding system).According to the present art, usually molten magnesium alloy is not to be handled being higher than under 650 degrees centigrade by metal-molding system or metal injection molding system, and this is because known machine barrel sub-assembly comprises the skin with Inconel-718 alloy.Specifically, because the chemistry related with the Inconel-718 alloy phase, it is impossible that molten magnesium alloy is heated to above about 650 degrees centigrade.When attempting (for example making the thin-wall metal goods, the portable case of mobile phone outer casing and/or computer) in time, go wrong, this is to be lower than about 650 degrees centigrade molten magnesium and often to have big relatively spheric granules (that is, comparing with the size of wanting molded thin-gage goods) because be heated to.Therefore big spheric granules often sticks in mold cavity, and described mold cavity is configured to mold walls goods as thin as a wafer, and described big spheric granules stops or to hinder molten magnesium mobile towards the edge of mold cavity unfriendly.Use is heated to the molded products that the molten magnesium that is lower than 650 degrees centigrade causes having unacceptable thin-walled character and/or quality.Make thin-gage goods thin as far as possible so that be extremely favourable in the possibility that leaves potentiality aspect the weight minimizing and also show the littler goods of making (with in the mold thin walls metallic article, may size comparing) by the current of the present art.
According to a first aspect of the invention, it provides a kind of metal-molding pipeline assembly (100), it comprises body (105), described body be configured to tolerate exceed about 650 degrees centigrade from about 30 to about 40 degrees centigrade higher temperature being used to handle moulding material, and described moulding material comprises the molten metal alloy with light metal alloy.
According to a second aspect of the invention, it provides a kind of metal-molding pipeline assembly (100), it has body (105), described body be configured to tolerate exceed about 650 degrees centigrade from about 30 to about 40 degrees centigrade higher temperature to be used to handle moulding material, and described moulding material comprises the molten metal alloy with light metal alloy, described body (105) has: (i) shell body (102), and it comprises the Inconel-720 alloy; Reach (ii) inner housing (104), it is assemblied in the shell body (102), and described inner housing (104) comprises corrosion resisting alloy.
Except that other technique effect, a technique effect of various aspects of the present invention be Inconel-720 alloy tolerance exceed about 650 degrees centigrade from about 30 to about 40 degrees centigrade higher temperature to be used to handle the fusion moulding material, described fusion moulding material comprises the molten metal alloy with light metal alloy, for example magnesium alloy.For (for example making the metal thin-wall goods, mobile phone outer casing or portable case etc.), the ability of processing molten magnesium improvement manufacturing thin-wall metal goods (promptly under being higher than 650 degrees centigrade, the ability of molded even thinner goods), and these thin goods can not make by using the pipeline operated under less than about 650 degrees centigrade temperature and/or the molding process of machine barrel.
