Abstract
The utility model discloses a prevent casting mould that roll pulled, including the runner, the rising head, cold mould and under casing, the rising head, cold mould and under casing all include the metal pattern, the rising head, be provided with the cavity in the metal pattern of cold mould and under casing, be provided with quartzy sand bed on the cavity inner wall, in the rising head in quartzy sand bed and the under casing thickness of quartzy sand bed be greater than the thickness of quartzy sand bed in the cold mould, quartzy sand bed make the cavity of metal pattern form the die cavity under surrounding, be equipped with the flexonics circle between runner and the rising head, be provided with the through -hole with the shape looks adaptation of the die cavity of rising head department in the flexonics circle, removable fixedly connected with layer board on the cavity inner wall of the metal pattern of under casing. Adopt after this kind of structure the die cavity for compound gold dust genotype chamber, the easy drawing of patterns can not produce and pull, utilized the flexonics circle, the runner has the removal space when the molten steel cooling strain makes the runner produce decurrent pulling force, utilized the layer board to prevent among the casting process that quartzy sand bed and cold mould throw off.
Description
Technical field
The utility model relates to a kind of casting die for roll casting, especially a kind of casting die preventing roll from pulling in knockout course.
Background technology
Roll is the vitals of roll forming.Roll needs to bear larger roll-force in the operation of rolling, uses casting die to carry out by a cast molding in the production of therefore roll.In prior art, roll casting mould comprises cast gate, rising head, cold mould and under casing, rising head, cold mould and under casing include metal pattern, the die cavity being used for cast molding is formed in metal pattern, easily pull the roll strength that the body of roll makes to cast out when shortcoming is demoulding difficulty, the demoulding after casting not very good, have impact on the quality of product; Too easily cause body of roll skin to produce chilling layer when cooling, what the processing of subsequent step was become is very difficult.
Utility model content
Easily pull the roll strength that the body of roll makes to cast out when the purpose of this utility model is demoulding difficulty after solving the casting of existing roll casting mould, the demoulding not very good, have impact on the quality of product; Body of roll skin is too easily caused to produce chilling layer, the very difficult problem that the processing of subsequent step is become when cooling.
The technical solution adopted in the utility model is: a kind of casting die preventing roll from pulling, comprise cast gate, rising head, cold mould and under casing, rising head, cold mould and under casing include metal pattern, cavity is provided with in the metal pattern of described rising head, cold mould and under casing, cavity inner wall is provided with quartz sand layer, in rising head in quartz sand layer and under casing the thickness of quartz sand layer be greater than quartz sand layer in cold mould thickness, make the cavity of metal pattern form die cavity under quartz sand layer surrounds.
As further improvement of the utility model, be provided with between described cast gate and rising head and flexibly connect circle, flexibly connect in circle and be provided with the through hole suitable with the shape of the die cavity at rising head place, removablely on the cavity inner wall of the metal pattern of described under casing be fixedly connected with supporting plate, the upper surface of described supporting plate contacts with the bottom of quartz sand layer in cold mould.
The beneficial effects of the utility model are: after have employed this structure, die cavity is multiple sand metal mold cavity, the easy demoulding of roll and can not producing pulls, utilize flexibly connect circle, when molten steel cools be out of shape make cast gate produce downward pulling force time cast gate have mobile space, utilize supporting plate to prevent quartz sand layer and cold mould in casting process from throwing off, solve the problem that roll demoulding difficulty causes pulling.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Shown in figure: 1 cast gate, 2 rising heads, 3 cold moulds, 4 under casings, 5 metal patterns, 6 quartz sand layers, 7 flexibly connect circle, 8 supporting plates.
Detailed description of the invention
Below in conjunction with figure, the utility model is described further.
A kind of casting die preventing roll from pulling, comprise cast gate 1, rising head 2, cold mould 3 and under casing 4, rising head, cold mould and under casing include metal pattern 5, described rising head, cavity is provided with in the metal pattern of cold mould and under casing, cavity inner wall is provided with quartz sand layer 6, in rising head, in quartz sand layer and under casing, the thickness of quartz sand layer is greater than the thickness of quartz sand layer in cold mould, the cavity of metal pattern is made to form die cavity under quartz sand layer surrounds, be provided with between described cast gate and rising head and flexibly connect circle 7, flexibly connect in circle and be provided with the through hole suitable with the shape of the die cavity at rising head place, removablely on the cavity inner wall of the metal pattern of described under casing be fixedly connected with supporting plate 8, the upper surface of described supporting plate contacts with the bottom of quartz sand layer in cold mould.
In the utility model, flexibly connect in circle and be provided with the through hole suitable with the shape of the die cavity at rising head place, such as, when the roll neck of roll is truncated cone-shaped (now roll neck cross section is trapezoidal), the through hole flexibly connected in circle is truncated cone-shaped and the trend of through-hole wall make through hole consistent with the trend of the cavity lateral at rising head place is large, little away from a side opening of roll neck near a side opening of roll neck.When molten steel cools is out of shape, roll casting makes cast gate produce downward pulling force by pulling cast gate, flexibly connects circle, make cast gate have mobile space due under cast gate, therefore can not produce pulling force by breaker roll.The roll demoulding after the convenient casting of quartz sand layer in cold mould.
Those skilled in the art should know; protection scheme of the present utility model is not limited only to the above embodiments; various permutation and combination and conversion can also be carried out on the basis of above-described embodiment; under the prerequisite without prejudice to the utility model spirit, the various conversion that the utility model carries out all are dropped in protection domain of the present utility model.
