Abstract
The utility model relates to a declining type pouring device of a casting piece, comprising a pouring cup, a sprue, a cross pouring gate and a flat casting piece; the large plane of the flat casting piece is arranged transversely, the end of the cross pouring gate is provided with a cold slug well, and the casting piece is communicated with the cross pouring gate by an internal pouring gate. The declining type pouring device has the advantages that liquid alloy is filled according to the preconceived filling sequence, so as to effectively prevent the disadvantages of casting lap, misrun and the like caused by rapid cooling of the liquid metal, and successfully cast and form the wing plane.
Description
Technical field
The utility model relates to a kind of oblique pouring device of foundry goods.
Background technology
Certain glide missile wing face is the main parts size of state key research and development program element, the long 1420mm of this aerofoil, and the cavity wall thickness has only 3mm in the 1235mm scope, and aerofoil is the streamline curved surface.Aerofoil adopts cast form.The basic wall thickness of aerofoil has only 3mm, and ultra-thin area 269*1235*2mm2 is shaped very difficult.So can Design of Runner System be trial-produceed successfully most important to this part.
Running gate system be liquid alloy filling foundry goods die cavity the passage of process.Correct design running gate system, and make liquid alloy steadily and reasonably be full of the die cavity of foundry goods is most important to the assurance of the shaping of this foundry goods and casting quality.
In trial-production in earlier stage, adopted multiple running gate system: (1) many cast gates disperse ingate.(2) the formula running gate system that drenches with rain.(3) disperse cast gate and pop gate to unite use.These running gate systems all are the common methods that solves casting pouring moulding problem.But end in failure.Reason is; Though these running gate systems have shortened the mobile distance of liquid metal, can cause that liquid flowing reaches the irregular of air scavenge in the die cavity, concerning this special foundry goods, be difficult to solve the moulding problem.
The utility model content
The technical problems to be solved in the utility model is: a kind of more reasonably oblique pouring device of aerofoil profile shape foundry goods is provided.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical problem that solves the utility model adopts is: a kind of oblique pouring device of foundry goods, comprise cup, sprue, cross gate and flat foundry goods, the big flat transverse setting of described flat foundry goods, the end of cross gate is provided with slag well, is connected by ingate between foundry goods and the cross gate.
According to another embodiment of the present utility model, the oblique pouring device of foundry goods comprises that further described ingate is elongated ingate along the cross gate direction.
According to another embodiment of the present utility model, the oblique pouring device of foundry goods comprises that further described foundry goods is a glide missile wing face foundry goods.
According to another embodiment of the present utility model, the oblique pouring device of foundry goods comprises that further described apparatus for pouring angle of inclination is 20 °.
According to another embodiment of the present utility model, the oblique pouring device of foundry goods comprises that further each sectional area ratio of described running gate system is that F is straight: in F horizontal stroke: the F=1: 5: 12.
The utility model has solved the defective that exists in the background technology, 1. adopts great opening oblique pouring system, and each sectional area ratio of running gate system is that F is straight: in F horizontal stroke: the F=1: 5: 12, reduced the filling resistance of liquid alloy.2. adopt 20 ° of inclined castings, make the filling order filling successively of liquid alloy, prevented liquid metal cooled fast effectively and casting flaws such as the cold shut that causes, misrun, successfully with the aerofoil castable by anticipation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Fig. 2 is the vertical view of die joint among Fig. 1
Wherein: 1, cup, 2, sprue, 3, cross gate, 4, foundry goods, 5, slag well, 6, ingate, 7, the filter tank.
The specific embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, a kind of oblique pouring device of foundry goods comprises cup 1, sprue 2, cross gate 3 and flat foundry goods 4, described flat foundry goods 4 big flat transverse settings, the end of cross gate 3 is provided with slag well 5, is connected by ingate 6 between foundry goods 4 and the cross gate 3.Wherein each sectional area ratio by running gate system is that F is straight: in F horizontal stroke: the F=1: 5: 12 design data, formula cast cross gate 3 adopts similar slit cast column along the from left to right elongated cross gate 3 of casting length direction.In addition, ingate 6 does not adopt distributing, and adopts along the elongated ingate of cross gate 3 directions.And, because cross gate 3 resistance ratios ingates 6 are little, liquid metal enters cross gate 3 along sprue 2 through filter tank 7 earlier and flows to cross gate 3 terminal slag wells 5, after cross gate 3 ends are full of, from the horizontal filling foundry goods 4 of ingate 5 terminal A, along with cross gate 3 upwards constantly is full of, liquid metal constantly constantly is full of foundry goods 4 from A to B place 2 like this, when having kept foundry goods 4 fillings, liquid metal remains higher temperature, good mobility.The gas of die cavity also constantly moves up by the filling direction simultaneously, discharges die cavity by the path that designs smoothly, has greatly reduced the filling resistance.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
Claims (5)
