Abstract
The utility model discloses a wheel mould bottom mould deformation-preventing device which comprises at least two pre-stress rings. At least one pre-stress ring is arranged on a back cavity of a bottom mould, and the distance from the pre-stress ring to a center hole is one third to a half of the radius of the bottom mould. Another pre-stress ring is arranged at the outmost end of the bottom mould and is in interference fit with the bottom mould. The pre-stress ring arranged on the back cavity of the bottom mould is embedded into the wheel mould bottom mould. The wheel mould bottom mould deformation-preventing device can solve the problem of thermal deformation of the wheel mould bottom mould, and prolongs service life of a mould.
Description
Technical field
The utility model relates to a kind of Casting Equipment, relates in particular to the casting wheel die.
Background technology
Wheel die is comprised of backform, bed die, limit mould.In prior art, a cover wheel mould can be produced tens thousand of products.The reason that causes mould to scrap is a lot, and one of them major reason is exactly die deformation.
Bed die is as the position that is easier to deform, and its distortion has certain rule.At first, the distortion of bed die center, because the bed die central temperature is relatively high, the bed die center raises up, and along with repeatedly colding and heat succeed each other of mould, stress discharges gradually, and the center is depressed deformation downwards again, and bed die center distortion is bigger than normal; Secondly, the distortion of bed die planar distortion, because the bed die diametric(al) arranges cooling duct, bed die easily occurs take the inlet and outlet direction as axis, the distortion that vertically upwarps.
Summary of the invention
The utility model aims to provide a kind of wheel die bed die anti-deformation device.
Technical solutions of the utility model are: wheel die bed die anti-deformation device, comprise at least two prestress annulars, at least one prestress annular is arranged on bed die back of the body chamber, and the distance in distance center hole is 1/3 to 1/2 of bed die radius, article one, prestress annular is arranged on the bed die outermost end, with the bed die interference fit.
The described prestress annular that is arranged on bed die back of the body chamber is embedded in the wheel die bed die.
As improvement of the present utility model, two prestress annulars are arranged on bed die back of the body chamber, and the distance between two prestress annulars is 20-50mm.
As improvement of the present utility model, three prestress annulars are arranged on bed die and carry on the back the chamber.
The thermal deformation problem that can solve the wheel die bed die of the present utility model extends die life.
Description of drawings
Fig. 1 is the wheel die bed die schematic diagram of prior art.
Fig. 2 is the schematic diagram of a kind of wheel die bed die of the utility model anti-deformation device.
In figure: 1-prestress annular A, 2-prestress annular B, 3-prestress annular C.
The specific embodiment
Technical solutions of the utility model are: a kind of wheel die bed die anti-deformation device, comprise at least two prestress annulars, at least one prestress annular is arranged on bed die and carries on the back the chamber, the distance in distance center hole is 1/3 to 1/2 of bed die radius, article one, prestress annular is arranged on the bed die outermost end, with the bed die interference fit.
The described prestress annular that is arranged on bed die back of the body chamber is embedded in the wheel die bed die.
As improvement of the present utility model, prestress annular A, prestress annular B are arranged on bed die back of the body chamber, and the distance between two prestress annulars is 20-50mm.
As improvement of the present utility model, three prestress annulars are arranged on bed die and carry on the back the chamber.
