Description
Technical field
The utility model relates to a kind of cast casting sand molds.
Background technique
Traditional sand casting process include molding, moulding, mould assembly casting and etc., be most widely used in Foundry Production
Casting method.The casting of the blade class of some XX, from tail portion to spindle nose transition thickness from 20mm to 150mm, and spindle nose having a size of
400mm, it is this kind of with curved surface and thickness widely different casting in both ends also generallys use sand casting and obtains.
Since this kind of casting is longer, being cast by using flat pouring technique, product rate is lower and curved surface riser not easy to place,
It is easier that curved surface is caused to deform if by the way of riser back suction, in turn results in casting and scrap.In the prior art, this kind of casting
Part production yield rate is lower.
Summary of the invention
The purpose of the utility model is to provide a kind of cast casting sand molds that can improve castings production yield rate.
To achieve the above objectives, the present invention adopts the following technical solutions: a kind of cast casting sand mold, including template,
The core box frame being fixed on the upside of template is placed with a simulation riser and a die model, two simulation riser on the template
Up and down with respect to and splice with identical as the size shape of riser used when cast article, the axis for simulating riser is laterally set
Set, two die models up and down with respect to and splice with identical as the casting size shape cast out is poured, the simulation riser and die model are put
It is placed in the core box frame for enclosing shape, the die model lower end surface is plane and sticks on the upside of template upper surface that the die model is left
Hold high right end low, and die model upper surface composition has curved surface, the simulation riser left end is affixed with core box frame inner wall, described
Simulation riser right end connects with die model left end, and the height and position of core box frame upper end is higher than on die model upper end and simulation riser
The height and position at end has the space for stepping down to sand between the die model right end and core box frame inner wall.
The utility model sandbox is used for the manufacture of cavity plate, reuses the utility model to obtain two cavity plates, two recessed
Mould is to constitute the type chamber for cast article；Since simulation axis is laterally arranged, formed cavity plate end has to be emitted for cooperating
Mouthful riser slot, to keep riser vertically arranged, can only 90 degree overturning grooves so that cavity plate is used to erect pouring technique, riser is not yet
It needs to be placed on cavity die camber side, the placement of riser in subsequent casting can be made more stable, to guarantee the yield rate of casting.Its
In, simulation riser can be actual half of riser, can also be the model of half of the riser directly processed on wood.
Preferably, the simulation riser right end height is less than or equal to die model left end height.
Preferably, the simulation riser and die model are integrally formed.Above-mentioned setting is so that the molding of groove is more convenient, imitates
Rate is higher.
The utility model has the advantages that castings production yield rate can be improved.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the utility model.
Specific embodiment
The utility model is further described below according to the drawings and specific embodiments.
As shown in Figure 1, a kind of cast casting sand mold of the utility model, including template 1, the core being fixed on the upside of template 1
Box frame 2, is placed with a simulation riser 3 and a die model 4 on template 1, two about 3 simulation riser it is opposite and splice with
The size shape of used riser is identical when cast article, and the axis for simulating riser 3 is laterally arranged, and two about 4 die models are opposite
And splice with identical as the casting size shape cast out is poured, simulation riser 3 and die model 4 are placed in the core box frame 2 for enclosing shape
Interior, 4 lower end surface of die model is plane and sticks on the upside of 4 upper surface of template that the high right end in 4 left end of die model is low, and 4 upper surface structure of die model
At there is curved surface, simulation 3 left end of riser is affixed with 2 inner wall of core box frame, and simulation 3 right end of riser connects with 4 left end of die model, core box side
The height and position of 2 upper end of frame is higher than 4 upper end of die model and simulates the height and position of 3 upper end of riser, 4 right end of die model and core box frame 2
There is the space for stepping down to sand 6 between inner wall.
Wherein, simulation 3 right end height of riser and 4 left end height of die model, simulation riser 3 and die model 4 are integrally formed.
The utility model sandbox is used for the manufacture of cavity plate, reuses the utility model to obtain two cavity plates, two recessed
Mould is to constitute the type chamber for cast article；Since simulation axis is laterally arranged, formed cavity plate end has to be emitted for cooperating
Mouthful riser slot, to keep riser vertically arranged, can only 90 degree overturning grooves so that cavity plate is used to erect pouring technique, riser is not yet
It needs to be placed on cavity die camber side, the placement of riser in subsequent casting can be made more stable, to guarantee the yield rate of casting.This reality
With novel have the advantages that castings production yield rate can be improved.
