Abstract
The utility model discloses a kind of mould preventing cast-internal shrinkage cavity or crack, it includes the upper molding sand of die cavity with foundry goods molding and lower molding sand, the core being filled in cast-internal and rising head, particularly, remove a part respectively in the inside of die cavity and form the multiple cavitys being connected with die cavity respectively, so that being formed with multiple thickenings matching with cavity in the both sides of foundry goods, plurality of cavity is located at the both sides of foundry goods respectively, and multiple cavitys of every side are spaced apart respectively along the fore-and-aft direction of mould.This utility model passes through easily shrinkage cavity or the foundry goods side wall in crack is provided with multiple thickenings, change the solidification shrinkage process of foundry goods so that foundry goods is less prone to crack or shrinkage cavity phenomenon, also reduce the quantity of rising head simultaneously, thus improve to expect rate, reduce production cost.
Description
Technical field
This utility model belongs to machine casting field and in particular to a kind of shaping mould preventing cast-internal shrinkage cavity or crack
Tool.
Background technology
The process exploitation of foundry goods now, because the structure design of foundry goods is substantially client providing, and it is main to cast producer
It is by technological design, the reasonable water inlet system of setting and system of risers it is ensured that the product produced meets delivery to customer and requires.
Original mentality of designing, is analyzed by simulation softward, the region of existing defects is carried out placing riser feeding, defect
Guide in rising head, then remove feeders is it is ensured that the quality of product.
But like this, because the product of some clients, the difference of structure, need to place multiple rising heads, lead to product
Must expect that rate is low（Note：The pouring molten iron weight of the weight of rate=product/total must be expected）.
Meanwhile, the position in shrinkage cavity or crack easily occurs typically in the side wall of foundry goods, along with must expect that rate is low, production quantity
In the case of identical, energy consumption and entreprise cost can be increased（Melting 1T molten iron needs about 650 degree of electricity）.
Content of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and providing a kind of improved prevents from casting
Part internal shrinkage or the mould in crack.
For solving above technical problem, this utility model adopts the following technical scheme that：
A kind of mould preventing cast-internal shrinkage cavity or crack, it includes the mo(u)ld top half with the die cavity of foundry goods molding
Sand and lower molding sand, the core being filled in cast-internal and rising head, particularly, remove a part simultaneously respectively in the inside of die cavity
Form multiple cavitys of being connected with die cavity respectively so that the both sides of foundry goods be formed with multiple with thickening that cavity matches
Part, plurality of cavity is located at the both sides of foundry goods respectively, and multiple cavitys of every side are respectively along the front and back of mould
To spaced apart.
It is preferably located at the symmetrical distribution of described cavity of both sides.
It is embodied as and preferred aspect according to one of the present utility model, cavity includes the first chamber on upper molding sand
Body, the second cavity being located on lower molding sand, the wherein first cavity and the second cavity are connected.
Specifically, the first cavity and the setting symmetrical above and below of the second cavity, and be in crescent shape.In immovable cast properties
Under the conditions of, by the setting of thickening, change the solidification shrinkage process of foundry goods cooling, reduce splitting of the easy appearance of foundry goods side wall
Seam or shrinkage cavity, improve the quality of foundry goods.
Preferably, the outline that each thickening is formed in foundry goods sidepiece is in circular arc.Not only save material, Er Qiecheng
Relatively attractive in appearance after type.
Additionally, mould also includes the venthole being arranged on molding sand.By the setting of venthole, effectively by steam
Discharge the quality it is ensured that after foundry goods molding.
Due to the enforcement of above technical scheme, this utility model compared with prior art has the advantage that：
This utility model passes through easily shrinkage cavity or the foundry goods side wall in crack is provided with multiple thickenings, changes casting
The solidification shrinkage process of part, so that foundry goods is less prone to crack or shrinkage cavity phenomenon, also reduces the quantity of rising head, thus improving simultaneously
Rate must be expected, reduce production cost.
Brief description
The utility model is described in more detail with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of this utility model foundry goods；
Fig. 2 is the cross-sectional schematic of the mould of this utility model foundry goods；
Wherein：1st, foundry goods；2nd, die cavity；3rd, upper molding sand；4th, lower molding sand；5th, core；6th, rising head；7th, cavity；71st, the first chamber
Body；72nd, the second cavity；8th, thickening；9th, venthole.
Specific embodiment
As depicted in figs. 1 and 2, the mould preventing cast-internal shrinkage cavity or crack of the present embodiment, it includes having
The upper molding sand 3 of the die cavity 2 of foundry goods 1 molding and lower molding sand 4, the core 5 being filled in cast-internal and rising head 6, particularly,
Remove a part respectively in the inside of die cavity 2 and form the multiple cavitys 7 being connected with die cavity 2 respectively, so that in foundry goods 1
Both sides are formed with multiple thickenings 8 matching with cavity 7, and plurality of cavity 7 is located at the both sides of foundry goods 1 respectively, and often
Multiple cavitys 7 of side are spaced apart respectively along the fore-and-aft direction of mould.
Specifically, positioned at the symmetrical distribution of cavity 7 of both sides.
In this example, the second cavity 72 that cavity 7 includes positioned at the first cavity 71 on upper molding sand 3, is located on lower molding sand 4,
Wherein first cavity 71 is connected with the second cavity 72.
Specifically, the first cavity 71 and the second cavity 72 setting symmetrical above and below, and be in crescent shape.In immovable foundry goods
Under conditions of energy, by the setting of thickening, change the solidification shrinkage process of foundry goods cooling, reduce foundry goods side wall and easily occur
Crack or shrinkage cavity, improve foundry goods quality.
Thickening 8 is matched with the first cavity 71 and the second cavity 72, and the outline being formed in foundry goods 1 sidepiece is in circle
Arc.Not only save material, and relatively attractive in appearance after molding.
Additionally, mould also includes the venthole 9 being arranged on molding sand 3.By the setting of venthole 9, effectively will
Steam discharges the quality it is ensured that after foundry goods 1 molding.
In sum, using the mould of the present embodiment, it has the advantage that：
1st, by the setting of multiple thickenings, change the solidification shrinkage process of foundry goods so that foundry goods is less prone to splits
Seam or shrinkage cavity phenomenon, improve the qualification rate of foundry goods；
2nd, can effectively reduce the quantity of rising head, thus improve to expect rate, reduce production cost.
Above this utility model is described in detail, but this utility model is not limited to the above embodiments.All bases
Equivalence changes or modification that spirit of the present utility model is made, all should cover in protection domain of the present utility model.
