Abstract
The utility model discloses a roll casting sand box with neck bush belongs to roll casting die utensil field, including the neck bush of sand box, sand box inner chamber parcel, the sand mould of neck bush parcel, adopt interference fit zonulae occludens between sand box inner chamber and the neck bush, adopt interference fit zonulae occludens between neck bush and the sand mould, the utility model discloses an install the neck bush in having the sand box that is not conform to the specification now additional, the technology design according to the sand mould requires adjustment sand box inner chamber size again, will have the sand box utilization that is not conform to the specification now, has avoided the production of sand box instrument expense.
Description
Technical field
This utility model relates to roll casting mould field, a kind of roll casting sandbox with neck bush.
Background technology
The mould that roll casting is used selects various sizes of sandbox according to dimension of roller, change along with roll product structure, special shape mo(u)lding box for roll casting is also required to again make, and thus has a large amount of sandbox and discards and leave unused for a long time, makes new sandbox simultaneously and also will produce the highest expense.
Utility model content
This utility model technical issues that need to address are to provide a kind of roll casting sandbox with neck bush, are coordinated the sandbox making the roll casting of different size can use same specification by neck bush.
For solving above-mentioned technical problem, this utility model be the technical scheme is that
There is the roll casting sandbox of neck bush, it is characterized in that: include neck bush, the sand mold of neck bush parcel that sandbox, sandbox inner chamber wrap up, use interference fit compact siro spinning technology between described sandbox inner chamber and neck bush, between described neck bush and sand mold, use interference fit compact siro spinning technology.
Further improvement is that of technical solutions of the utility model: described neck bush external diameter is more than sandbox internal diameter 0.01 mm～3 mm.
Further improvement is that of technical solutions of the utility model: described neck bush thickness is 10mm～80mm.
Further improvement is that of technical solutions of the utility model: described neck bush is provided with many sets according to different-diameter.
Further improvement is that of technical solutions of the utility model: described neck bush material is identical with sandbox material.
Owing to have employed technique scheme, the technological progress that this utility model obtains is:
This utility model is by installing neck bush additional in the existing sandbox fallen short of specifications, the production engineering specifications according still further to sand mold adjusts sandbox inner chamber size, is utilized by the existing sandbox fallen short of specifications, it is to avoid the generation of sandbox tool expense.
This utility model is assembled into different-thickness by the interference fit of the neck bush of many set different sizes, then meets the specification between sand mold and sandbox by pad regulation, makes neck bush make simple operations more flexible.
Accompanying drawing explanation
Fig. 1 is this utility model perspective view；
Fig. 2 is the full sectional view that this utility model master regards；
Wherein, 1, sandbox, 2, neck bush, 3, sand mold.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further details:
As shown in Figure 1 and Figure 2, there is the roll casting sandbox of neck bush, including sandbox 1, neck bush 2, sand mold 3, interference fit compact siro spinning technology is used between described sandbox 1 inner chamber and neck bush 2, and it is peripheral that sandbox 1 is wrapped in neck bush 2, use interference fit compact siro spinning technology between described neck bush 2 and sand mold 3, and neck bush 2 is wrapped in sand mold 3 periphery；Interference fit between sandbox 1, neck bush 2 and sand mold 3 ensures do not have space between each structure, makes roll quality in casting cycle and safety be protected.
As in figure 2 it is shown, neck bush 2 external diameter is more than sandbox 1 internal diameter 0.01 mm～3 mm, neck bush 2 is assembled in sandbox 1 mechanically；Sand mold 3 is assembled in neck bush 2 again by mechanical system；Assemble and between rear sandbox 1 and neck bush 2, there is no between space, and sand mold 3 and neck bush 2 also not have space, it is ensured that security reliability during casting；The amount of neck bush 2 and the interference fit of sandbox 1 is in the reasonable scope, it is ensured that neck bush 2 and sandbox 1 will make neck bush 2 can fit into sandbox 1 more easily internal on the premise of relative movement.
Neck bush 2 thickness of the present utility model is 10mm～80mm, the thickness of neck bush 2 is adjusted by production engineering specifications and the size of sandbox 1 according to sand mold 3, can be in close contact between sandbox 1 and sand mold 3 meeting neck bush 2, reduce sand mold 3 usage amount while make excessive sandbox 1 can twice laid, economize on resources.
As shown in Figure 1, neck bush 2 is provided with many sets according to different-diameter, can fit together with interference fit between each set neck bush 2, make neck bush 2 can unify model batch production, then when producing the roll of all size, adjusted the thickness of neck bush 2 by the quantity adjusting neck bush 2, then make to be in close contact between sand mold 3 and sandbox 1 by the regulation of the instrument such as pad and very close to each other, making this utility model operation more flexible.
Neck bush 2 material of the present utility model is identical with sandbox 1 material, sandbox 1 material is generally irony or wooden, makes 1 neck bush 2 have the identical coefficient of expansion with the sandbox 1 identical guarantee of material, makes during casting, gap is not produced, it is ensured that the safety of casting and quality between each assembly.
Operation principle:
This utility model uses the mode neck bush 2 of interference fit to be reduced by sandbox 1 inner chamber, is reducing the usage amount of sand mold 2, save roll casting cost in roll casting work；Simultaneously by the most inappropriate sandbox 1 twice laid originally, save instrument cost.
Neck bush 2 of the present utility model uses many sets of different-diameter, is assembled into the neck bush 2 of different-thickness by the interference fit of each set neck bush 2, then makes between sandbox 1 and sand mold 3 very close to each other by the adjustment of pad, and processing is simple, flexible operation.
