Abstract
The utility model discloses a casting die for a roller of a filling machine. The casting die comprises a lower die and an upper die, wherein the lower die is provided with a concentric pillar, the upper die is provided with a concentric hole, and the circle centers of the concentric pillar and the concentric hole are located in a same axial line. According to the casting die disclosed by the utility model, for the roller, with high requirement on precision, of the filling machine, the lower die with the concentric pillar and the upper die with the concentric hole are set, so that in the process of casting polyurethane on the roller, the concentricity and degree of symmetry of the roller are ensured, therefore, the production efficiency and qualified rate of products are greatly improved; and the casting die is simple in structure, and extremely practical.
Description
Technical field
The utility model relates to the casting mold technical field, relates in particular to a kind of bottle placer roller bearing casting mold.
Background technology
Roller bearing claims again roller bearing, and referring to Fig. 4, its structure comprises outer ring 4, inner ring 3 and the polyurethane 5 between 4 inner rings 3 of outer ring.The quality of roller bearing depends primarily on the symmetry at the axiality of inner ring 3, outer ring 4 and inner ring 3,4 two ends, outer ring.
The roller bearing that is used for bottle placer, its concentricity and symmetry require all to be no more than 0.2mm, for height like this requirement accurately, make comparatively difficulty, are difficult to realize batch production.
Therefore, need especially a kind of bottle placer roller bearing casting mold, to solve problems of the prior art.
The utility model content
The purpose of this utility model is to have relatively high expectations in order to solve in prior art the bearing accuracy that is used for bottle placer, makes comparatively difficulty, and being difficult to realize the defective produced in batches provides a kind of bottle placer roller bearing casting mold to solve the problems referred to above.
A kind of bottle placer roller bearing casting mold comprises counterdie and patrix, and described counterdie arranges concentric column, and described patrix arranges concentric hole, and the center of circle of described concentric column and concentric hole is on same axis.
In the utility model, on described counterdie, cylinder boss is set, the cylinder concave station is set on described patrix, described cylinder boss and cylinder concave station cooperatively interact, and the center of circle of described cylinder boss, cylinder concave station and concentric column, concentric hole is on same axis.
In the utility model, on described counterdie, counterdie and concentric column contacted position arranges spacing cylindrical groove, in described spacing cylindrical groove, spacing cylinder boss is set.
In the utility model, the concentricity of described concentric column and concentric hole is 0.02mm-0.2mm.
In the utility model, described counterdie and upper die combination mould and the exposed corner angle of patrix at present arrange respectively arc transition.
A kind of bottle placer roller bearing casting mold of the present utility model, compare with existing product, product for this high-precision requirement of bottle placer roller bearing, setting has the counterdie of concentric column and the patrix with concentric hole, guarantee its concentricity and symmetry when making the roller bearing cast polyurethane, greatly improve efficient and the qualification rate of producing product, simple in structure, very practical, realize the purpose of this utility model.

The specific embodiment
Below in conjunction with the accompanying drawing illustrated embodiment, the utility model is further described.
Embodiment
As shown in Fig. 1～3, Fig. 1 is structural representation of the present utility model; The structural representation of Fig. 2 the utility model counterdie; Fig. 3 is the structural representation of the utility model patrix.
A kind of bottle placer roller bearing casting mold comprises counterdie 1 and patrix 2, and counterdie 1 arranges concentric column 11, and patrix 2 arranges concentric hole 21, and the center of circle of concentric column 11 and concentric hole 21 is on same axis; Be that concentric column 11 and concentric hole 21 have concentricity preferably, the concentricity of the utility model special requirement is in 0.2mm.
On counterdie 1, counterdie 1 arranges spacing cylindrical groove 13 with concentric column 11 contacted position, and spacing cylindrical groove 13 is interior arranges spacing cylinder boss 12.
The concentricity of concentric column 11 and concentric hole 21 is 0.02mm-0.2mm.
When counterdie 1 makes up with patrix 2, counterdie 1 arranges respectively arc transition with the exposed corner angle of patrix 2.
When in use, cylinder concave station 22 amalgamations of patrix 2 are on the cylinder boss 12 of counterdie 2, roller bearing inner ring 3 is inserted on the concentric column 11 that equates with inner ring 3 sizes, the concentric hole 21 that equates with outer ring 4 outside dimensions is put in roller bearing outer ring 4, make concentricity and the symmetry of inner ring 3, outer ring 4 obtain maximum the guarantee, again at the interior injection polyurethane 5 of inner ring 3 and outer ring 4, thereby complete the making of roller bearing.
A kind of bottle placer roller bearing casting mold of the present utility model, compare with existing product, product for this high-precision requirement of bottle placer roller bearing, setting has the counterdie of concentric column and the patrix with concentric hole, guarantee its concentricity and symmetry when making the roller bearing cast polyurethane, greatly improve efficient and the qualification rate of producing product, simple in structure, very practical, realize the purpose of this utility model.
The above-mentioned description to embodiment is can understand and use the utility model for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and in the General Principle of this explanation is applied to other embodiment and needn't pass through performing creative labour.Therefore, the utility model is not limited to above-described embodiment, and those skilled in the art are according to announcement of the present utility model, and not breaking away from the improvement that the utility model category makes and revise all should be within protection domain of the present utility model.
