Abstract
The invention discloses a process for forming titanium alloy die castings. The process comprises the following steps: (1) placing an iron core; (2) closing a die; (3) locking the die; (4) pulling the core through an oil cylinder; (5) carrying out die casting; (6) pulling the core through the oil cylinder; (7) opening the die; (8) outputting the casting. During die casting, the die is opened and then the core is pulled through the oil cylinder; after oil in the oil cylinder is unloaded, no pressure exists; the long-time load movement is avoided so that a core shaft of the oil cylinder is not broken and oil leakage is not serious.
Description
Technical field
The invention belongs to die-casting technique field, particularly a kind of moulding process of titanium alloy die casting.
Background technology
Die casting is a kind of part of compression casting, use the compression casting machinery die casting machine installing casting die, the metal such as copper, zinc, aluminum or aluminum alloy being heated to be liquid state is poured into the feeding mouth of die casting machine, through die casting machine die casting, cast out the copper of the shape and size of mould restriction, zinc, aluminium part or aluminum alloy part, such part is just called die casting usually.Die casting has different calls in different places, as diecast parts, die-casting, die casting, die casting aluminium, die case zinc part, die casting copper piece, copper die casting, zine pressure casting, aluminium diecasting aluminium diecasting, aluminium pressure alloy-steel casting, aluminium alloy compression casting part etc.
Summary of the invention
In order to realize object of the present invention, the present invention by the following technical solutions:
A kind of moulding process of titanium alloy die casting, described titanium alloy casting is according to the following material composition of parts by weight: alundum (Al2O3) 20-38 part, manganese dioxide 6-15 part, copper sulphate 8-14 part, Iron concentrate 5-7 part, chrome-molybdenum steel 2-5 part, silica 6-8 part, brass 2-8 part, tinplate 3-7 part, nickel hydroxide 6-9 part, titanium dioxide 15-34 part;
Concrete forming step comprises:
1) iron core is placed;
2) matched moulds;
3) locked mode;
4) loose core of oil cylinder;
5) die casting;
6) loose core of oil cylinder;
7) die sinking;
8) part is gone out.
Beneficial effect of the present invention: loose core of oil cylinder after first die sinking during die casting of the present invention, in oil cylinder after emptying without pressure, avoid long load action to make oil cylinder core axle fracture, leakage of oil serious.
Detailed description of the invention
Embodiment provided by the invention is described in further detail:
A kind of moulding process of titanium alloy die casting, described titanium alloy casting is according to the following material composition of parts by weight: alundum (Al2O3) 20-38 part, manganese dioxide 6-15 part, copper sulphate 8-14 part, Iron concentrate 5-7 part, chrome-molybdenum steel 2-5 part, silica 6-8 part, brass 2-8 part, tinplate 3-7 part, nickel hydroxide 6-9 part, titanium dioxide 15-34 part;
Concrete forming step comprises:
1) iron core is placed;
2) matched moulds;
3) locked mode;
4) loose core of oil cylinder;
5) die casting;
6) loose core of oil cylinder;
7) die sinking;
8) part is gone out.
Loose core of oil cylinder after first die sinking during die casting of the present invention, in oil cylinder after emptying without pressure, avoid long load action to make oil cylinder core axle fracture, leakage of oil serious.
In this description, the present invention is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, description is regarded in an illustrative, rather than a restrictive.
