Abstract
The casting method that a kind of position of splitter from the melt introduction part for being arranged on casting molds casts the chamber that melt is imported in mold, wherein, the shell that the melt of position of splitter is contacted is made of copper or copper alloy, the temperature of the chamber of the mold at casting initial stage is set as defined mould temperature, and, the temperature at the casting initial stage of position of splitter is set as 65 DEG C hereinafter, being cast.
Description
Technical field
The present invention relates to the casting methods of the metal material for the formed products that aluminium alloy is obtained by high-pressure casting, particularly relate to
And shorten the technology of the circulation time of casting.
Background technology
In the molding of high die casting etc., the chamber into mold is set to import in the melt introduction part of casting molds sometimes molten
The component for being referred to as position of splitter of liquid.At this point, in casting, when the melt being pressed into from push rod encounters the position of splitter, melt passes through
The access being formed in position of splitter is imported into the chamber in mold.Position of splitter is in the component for forming mold, and melt initially connects
Tactile component particularly bears fierce cold cycling repeatedly.In addition, the most thick material handle of wall thickness in position of splitter and moulding shape
Portion is connected with access, it requires comparable cooling efficiency.In addition, since melt being required smoothly to flow into chamber, also, also
The function of solidifying it is sought, therefore, cooling body is equipped in position of splitter.
But these surface treatment epitheliums have thermal insulation, therefore, it may occur that reduce thermal conductivity the problem of.It is in addition, this
It is low to be surface-treated epithelium oxidative resistance, therefore, has the shortcomings that crackle and stripping easily occurs.Occur on surface treatment epithelium
During crackle, molten damage occurs for position of splitter, so must remove position of splitter from mold, implements surface treatment, becomes miscellaneous.In addition,
Even the position of splitter of copper alloy, when shortening circulation time, inside cooling media boiling, cooling efficiency reduces, former material (injection
Material) temperature rise, cause expect shank rupture or scaling loss, pound side etc. it is various operation deteriorate (working efficiency is substantially disliked
Change).
Invention content
The purpose of the present invention is to provide a kind of casting method and casting moulds, can inhibit the founding materials and copper of aluminium etc.
The reaction of the position of splitter of system carries out smooth casting, also, the cooling efficiency by greatly improving the position of splitter, effectively contracts
Short circulation time.
The intracavitary that melt is imported to the mold from the position of splitter of the melt introduction part for being arranged on casting molds is cast
Casting method in, the position that the melt of the position of splitter is contacted is made of copper or copper alloy, by the mould at the initial stage that casts
The chamber temperature of tool is set as defined mould temperature, also, the temperature at the casting initial stage of the position of splitter is set as less than 65 DEG C
And it is cast.
Specific embodiment
According to the embodiment of the present invention, from the position of splitter for the melt introduction part for being arranged on casting molds to the mold
Chamber import melt casting method in, the position that the melt of the position of splitter is contacted is made of copper or copper alloy, will be cast
The chamber temperature of the mold at initial stage is set in defined mould temperature, also, the temperature at the casting initial stage of the position of splitter is set
Less than 65 DEG C are scheduled on to be cast.
According to the above method, by by the casting initial stage temperature for the position of splitter being made of copper or copper alloy be set as 65 DEG C with
Under, aluminium when founding materials contacted with the position of splitter when, the two reaction before stage, the formation of the solidification layer of founding materials and
Solidification layer caused by solidification shrinkage easily occurs from the stripping of position of splitter.Therefore, it is possible to carry out the anti-of founding materials and position of splitter
The smooth casting that should be inhibited.In addition, material shank can promptly solidify, as a result, circulation time can be realized
Shortening.
In the above-mentioned methods, the position of splitter can be with cooling back with what is cooled down to the position of splitter inside it
The cooling component of the steel on road.
Claims (3)
1. a kind of casting method is that melt is imported the mold from the position of splitter for the melt introduction part for being arranged on casting molds
The casting method that intracavitary is cast, which is characterized in that the position of splitter, position that melt is contacted are by copper or copper alloy structure
Into, cast the chamber of the mold at initial stage temperature be set as defined in mould temperature, also, casting initial stage of the position of splitter
Temperature is set as 65 DEG C hereinafter, being cast.
2. casting method according to claim 1, wherein, the position of splitter has cold to position of splitter progress inside it
But the cooling component of the steel of cooling circuit.
3. a kind of casting mould, which is characterized in that have：Stent；Relative to the possible But moving die of stent advance and retreat；If
In in the stent, there is the cast gate hoop of inner space being open in the advance and retreat direction of the But moving die；Mounted on it is described can
On dynamic model, the position of splitter opposite with the cast gate hoop, the position of splitter has cylindric shell and setting inside the shell cold
But piece, the shell have the front end of the shape for the inner space for entering the cast gate hoop, what the melt of the shell was contacted
Surface is made of copper or copper alloy, does not form surface epithelium, the cooling fin on the surface being made of copper or copper alloy
With the cooling circuit of cooling medium cooled down for flowing to position of splitter.
