Abstract
The utility model discloses a circular casting rough special sandbox, relating to the technical field of casting and comprising a sandbox (2), a lantern ring (7) and a mould (4), wherein, the sandbox (2) is arranged in a circular shape, and the outer edge of the sandbox (2) is provided with an outer border (5) for placing the lantern ring (7). The upper surface of the mould (4) is provided with a riser (6) and a pouring channel (3), and a cavity (1) of the mould (4) is in a horizontal turning hook shape. As a pouring way of the circular sandbox is adopted, the circular casting rough special sandbox can effectively reduce the amount of usage of sand. The utility model has the advantages of simple structure and low cost, and the like, the sandbox can be used multiple times.
Description
Technical field:
The utility model relates to casting technology field, especially relates to a kind of annular cast blank special shape mo(u)lding box.
Background technology:
Prior art is made the large-sized annular cast blank and is adopted the forging mode to realize usually, and forging is to utilize metal forming machinery that metal stock is exerted pressure, and makes it produce plastic deformation to obtain required forging; Because the Forging Technology complexity wants to obtain repeatedly forging and pressing ability of a large-sized annular cast blank moulding preferably usually, and is time-consuming; Want to obtain fast the large-sized annular cast blank, very big for the molding sand demand, and to produce more discarded object, thereby production cost is also higher.
Summary of the invention:
In order to overcome the deficiency in the background technology, the utility model provides a kind of annular cast blank special shape mo(u)lding box, annular cast blank special shape mo(u)lding box described in the utility model is owing to adopted the pouring type of ring-type sandbox, can effectively reduce the use amount of molding sand, and the utlity model has simple in structure, cost is low, and sandbox such as can repeatedly utilize at advantage.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of annular cast blank special shape mo(u)lding box, comprise sandbox, the collar and mould, described sandbox is the toroidal setting, outer rim at sandbox is provided with the outer of placing the collar, the upper side of described mould is provided with rising head and running channel, the die cavity of described mould is set to "] " shape, that is to say that wherein the outside of mold cavity is sky.
Described annular cast blank special shape mo(u)lding box, the rising head that is provided with in the upper side of mould is at least one.
Described annular cast blank special shape mo(u)lding box, the running channel that the upper side of mould is provided with is at least one.
Owing to adopted technique scheme, the utlity model has following beneficial effect;
Annular cast blank special shape mo(u)lding box described in the utility model is by sandbox and mould; Described sandbox is made of iron and steel, is annular, and its internal diameter is a bit larger tham the external diameter of annular cast mould, and its wall thickness can be decided according to actual needs; The utility model lowered greatly molding sand use amount, saved molten steel, reduced production cost and working strength of workers because the annular cast blank do not need pattern draft, reduced the weight of cast steel gear blank, also improved the quality of foundry goods.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
In the drawings: 1, die cavity; 2, sandbox; 3, running channel; 4, mould; 5, outer; 6, rising head; 7, the collar.
The specific embodiment:
In Fig. 1, a kind of annular cast blank special shape mo(u)lding box, comprise sandbox 2, the collar 7 and mould 4, described sandbox 2 is the toroidal setting, outer rim at sandbox 2 is provided with the outer 5 of placing the collar 7, the upper side of described mould 4 is provided with rising head 6 and running channel 3, and the die cavity 1 of described mould 4 is set to "] " shape, that is to say that wherein the outside of mould 4 die cavities 1 is sky; The rising head 6 that is provided with in the upper side of mould 4 is at least one; The running channel 3 that the upper side of mould 4 is provided with is at least one.
During use mould is put into sandbox 2, behind the described collar 7 inwall daubs, be enclosed within the outside of mould 4 then, begin cast after preparation is finished and just can until finishing.
