The casting system of the vertical separation of unit.
Background technique
In order to meet productivity requirement, the greensand foundry production line of automation is increasingly by small-sized cast iron high-volume
With the welcome of long-term production.The molding machine of vertical separation is (such as by the Disamatic of DISA Industries A/S manufacture without case
Molding machine) up to 450-500 mold can be produced and per hour commonly used in castings of gray cast iron.In Disamatic machine, one
A model half part is installed in the end of the extrusion piston of hydraulic operation, and it is (so-called that another half part is mounted to oscillating deck
, because it can move and be swung away from mold).This machine is able to produce hard, rigid, without case greensand mold.
In typical casting technique (mold horizontally or vertically separated), molten metal is poured into and defines casting shape
In the pre-formed mold cavity of shape.But as metal freezing, contraction lead to shrinkage cavity, this causes again can not in final casting
The defect of receiving.Overcome above by additional (usually closed) volume or chamber being connected to casting cavity is provided, so that molten
Melt metal to enter also by the opening drawn from casting cavity and fill additional cavity to form metal reservoir.During solidification,
Molten metal in the reservoir is discharged and flow back into casting cavity the contraction for compensating casting by opening.This is referred to as casting
Feeding, and reservoir is commonly known as " feed inlet ", " charging is oral " or " riser ".Importantly, the gold in feeder sleeve cavity
Belong to and kept for the melting time be longer than the metal in mold cavity, and is placed close to the appropriate part of casting.
It is referred to as " natural feeder " in the feeder of material (usually sand) molding identical with casting molds are formed.
Feeder chamber is usually cylindrical or conical butt, and bottom has opening, and is usually completely enclosed in mold.These
Commonly known as " closed " or " blind " feed inlet or riser.When being linked together by two sseparated half modules, feeder
It can be vertically located at the separator bar of mold.Selectively, it can be fully located in a half part of mold and be in
Horizontal position.The type of feeder will be determined by the size and configuration of casting and runner system.
In certain casting systems, feeder can be " open ", and thus the top of feeder is located at the top of mold,
So that in use, the metal at the top of feeder will be opened wide towards atmosphere.It is shown in the Casting Equipment described in GB 1357410
This feeder, wherein metal enters mold cavity via cast gate under stress, fills casting cavity, then passes through opening upwards stream
Enter feeder chamber.When casting is cooling and starts to shrink, the metal in feeder is flow back into casting by same opening, so that
Feeder opening now acts as outlet, and it serves as entrance before.
Side-feeder is commonly referred to as feed system, it is intended to which the thermal loss for reducing feeder cools down it more slowly simultaneously
Keep liquid longer, so that a greater amount of charging metals can be provided for casting.This means that feeder can be reduced
Size (compared with natural feed device), thus assign improve casting yield benefit, allow to single mould plate and thus
More casting are produced on single mold, to reduce repairing (cleaning) cost.These feed systems or feeder sleeve are usual
Be the refractory material shape of chemical adhesion, and be made into height be insulated and/or it is exothermic.Exothermic sleeves connect with molten metal
It is lighted when touching, and generates heat to postpone the solidification of the intracavitary metal of feeder.
Initially, the conventional method of the mold production charging casting of vertical separation is using natural sand riser.With vertical point
Every mold in the increase of the quantity and complexity of casting that produces and then improve the casting quantity of yield and every mold
It is required that feeder sleeve starts to be used, generally by inserting the sleeve into mold using automatic core setter in molding cycle
Connecting line on.However, these sleeves are applied to might have problem on molding connection (or separation) line, and it is closed in mold
Before or mold be closed during sleeve outflow location.As described in GB2372004A, there is the sleeve of external flanges can by using changing
Partly to alleviate this problem.
Feeder is placed on the limitation on molding connecting line but also being difficult to supply heavier, the thicker part of casting.
This can be by using metal gasket or cooling next gram of feed path to form independence (the usual thickness) part for leading to casting
Clothes.But the validity of this method is restricted, and there are several deficiencies, lead to cleaning cost increase and casting output
It reduces.Natural sand riser can also be in conjunction with adding the cushions or cooling down use, still, this method limited efficacy, because of its significant drop
Low casting yield, and usually there is limited space on mould plate, the especially feelings in the multiple casting of each mold arrangement
Under condition.
