Description

A kind of sandbox for casting rolled mortar wall or broken wall
Technical field
The utility model relates to casting tooling device technical field, especially a kind of sandbox for casting rolled mortar wall or broken wall.
Background technology
Rolled mortar wall and broken wall are the main wearing pieces of cone crusher.Usually adopt the method for sand casting to produce this class foundry goods, its material is generally potassium steel, and its general structure is cone structure.
As shown in Figure 1, sandbox casing 1 outer wall of traditional sandbox adopts square or rectangle structure, and this class sandbox versatility is good, but when producing potassium steel rolled mortar wall and broken wall, need to use more sand, exist mold thickness big, insufficient strength, problems such as product easy deformation.These problems have not only reduced dimensional stability, but also have increased production cost.
High manganese steel casting 4 shrinks big, in the process of pouring into a mould and solidifying, the casting sandbox has born very large expansive force, simultaneously, rolled mortar wall and broken wall foundry goods are owing to be cone structure, outside expansive force is very big, and this causes frequent can not being effectively controlled of size of potassium steel rolled mortar wall or broken wall foundry goods, because scrapping of causing of size distortion is high.
The utility model content
The technical problems to be solved in the utility model is: a kind of sandbox for casting rolled mortar wall or broken wall is provided, and the intensity of sandbox is higher, and the mold thickness reduction, saves production cost.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of sandbox for casting rolled mortar wall or broken wall, has the sandbox casing, described sandbox casing has cope and drag box, described cope has circular lid, described drag box has the taper wall body, the inwall of described drag box matches with the foundry goods outer wall that needs casting, the described foundry goods that needs to cast is rolled mortar wall foundry goods or broken wall foundry goods, the taper shape of the outer wall of described drag box for progressively dwindling downwards, described cope and drag box are provided with the case shelves, leave rising head on the case shelves of described cope, leave running channel and cast gate on the case shelves of described drag box.
Further, be symmetrical arranged the hanging axis that is useful on lifting on the outer wall of described cope, the outer wall of drag box, the bore of described cope is consistent with the bore on drag box top.
Further, be flat bottom the described drag box.
The beneficial effects of the utility model are: the inwall of drag box of the present utility model matches with needing the casting outer wall, and the taper shape of the outer wall of drag box for progressively dwindling downwards makes each position of foundry goods cool off uniformity, and dimensional stability improves greatly.By the distortion of foundry goods with scrap the loss that causes and significantly reduce, simultaneously, in contrast to square or rectangular sandbox in the prior art, the utility model can be saved the sand about 1/3.Upper and lower sandbox is provided with the case shelves, and these case shelves are conducive to strengthen the intensity of sandbox and guarantee that sandbox is indeformable.Upper and lower sandbox is symmetrical arranged hanging axis, is convenient to lifting and mould turnover.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the casting technique schematic diagram of prior art;
Fig. 2 is the combination schematic diagram of upper and lower sandbox in the utility model;
Fig. 3 is casting technique schematic diagram of the present utility model;
Wherein: 1, sandbox casing, 11, cope, 12. drag boxs, 3. hanging axis, 4, foundry goods, 5. core.
The specific embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
As shown in Figure 2, a kind of sandbox for casting rolled mortar wall or broken wall, has sandbox casing 1, sandbox casing 1 has cope 11 and drag box 12, cope 11 has circular lid, drag box 12 has the taper wall body, the inwall of drag box 12 matches with foundry goods 4 outer walls that need casting, needing the foundry goods 4 of casting is rolled mortar wall foundry goods or broken wall foundry goods, the taper shape of the outer wall of drag box 12 for progressively dwindling downwards, cope 11 is provided with the case shelves with drag box 12, leaves rising head on the case shelves of cope 11, leaves running channel and cast gate on the case shelves of drag box 12.
Be symmetrical arranged the hanging axis 3 that is useful on lifting on the outer wall of the outer wall of cope 11, drag box 12, the bore of cope 11 is consistent with the bore on drag box 12 tops.
The inwall of drag box 12 matches with foundry goods 4 outer walls that need casting, and the taper shape of the outer wall of drag box 12 for progressively dwindling downwards makes foundry goods 4 each position cool off uniformities, and dimensional stability improves greatly.By the distortion of foundry goods 4 with scrap the loss that causes and significantly reduce, simultaneously, in contrast to square or rectangular sandbox in the prior art, the utility model can be saved the sandbox sand about 1/3.Upper and lower sandbox 11,12 is provided with the case shelves, and these case shelves are conducive to strengthen the intensity of sandbox and guarantee that sandbox is indeformable..Upper and lower sandbox 11,12 is symmetrical arranged hanging axis 3, is convenient to lifting and mould turnover.
As shown in Figure 3, according to the casting process scheme of rolled mortar wall or broken wall, rolled mortar wall foundry goods or broken wall foundry goods are placed on drag box 12, rising head is arranged on cope 11, upper and lower sandbox 11,12 is provided with the case shelves, and the case shelves are a little less than corresponding case mouth.The case shelves of drag box 12 are reserved the position of running channel and cast gate, and the case shelves of cope 11 are reserved the position of rising head.Foundry goods 4 is placed in the drag box 12, places core 5 in the foundry goods 4.As seen from Figure 3, with respect to sandbox shown in Figure 1 in the prior art, sandbox outer wall place can save more sandbox sand, and the utility model can be saved the sandbox sand about 1/3.
If adopt waterglass carbon dioxide hardening technology, calculate according to 1 ton foundry goods, can save the sand cost about 100 yuan, can save the waterglass about 60 yuan, can save other costs such as carbon dioxide about 40 yuan, save altogether 200 yuan per ton.Calculate according to the scale of producing 5000 tons of rolled mortar walls and broken wall per year, only just can save 100 ten thousand yuan of costs in 1 year.
Be enlightenment with above-mentioned foundation desirable embodiment of the present utility model, 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.
