Abstract
The present invention provides a casting apparatus for eliminating cracks of a thick and large belt pulley shaft hole. According to the present invention, according to a casting mold, an inner gate and an annular transverse runner are connected; a rectangular pouring riser is arranged above the outer wall of a belt pulley casting mold along the belt pulley circumference outer ring by adopting the shaft hole of the belt pulley casting mold as the circle center; a proper amount of chill is arranged on the sand mold inner bottom surface of the thick and large position of the belt pulley cast; and the rectangular pouring riser is uniformly distributed along the circumference direction above the cast outer wall, the mold casting chill is uniformly arranged on the bottom surface of the middle thick position of the thick and large belt pulley casting mold, and the annular transverse runner is connected with the belt pulley casting mold through the inner gate. With the casting apparatus, the cooling rate of the thick and large position between the cast outer wall and the shaft hole is accelerated, the cracks can be eliminated, the operation process can be simplified, and the casting cost can be reduced.
Description
Technical field
The present invention relates to the thick massive casting device of casting pig, relate in particular to the thick large belt wheel porous dehiscence of a kind of elimination line casting device.
Technical background
At present, the casting device of existing thick large Grey Iron Belt Pulley, for fear of foundry goods in process of setting because liquid state is shunk and solidification shrinkage, at foundry goods final set position, produce shrinkage cavity and porosity, and in order to eliminate casting stress, mainly rely on running gate system and cross ingate blind riser and carry out feeding, but cross ingate blind riser, can produce hot-spot, increase casting stress, foundry goods bulk temperature is evenly distributed with to negative interaction.Therefore,, although said apparatus can make foundry goods occur that shrinkage and sink phenomenon is less, in foundry goods axis hole, easily produce cross crackle.
Summary of the invention
The object of the invention is to avoid the deficiencies in the prior art, a kind of casting device for thick large Grey Iron Belt Pulley is provided, accelerate the cooling velocity of thick large part between foundry goods outer wall and axis hole, can eliminate the crackle in foundry goods axis hole.
Its technical scheme is, a kind of casting device of eliminating thick large belt wheel porous dehiscence line, and described cast model is connected with circular cross-runner by ingate; It is the center of circle that described cast model be take the axis hole of belt wheel mold, and rectangle is built rising head and is arranged on described belt pulley mold outer wall top along on belt wheel circumference outer ring; The relevant mold inner bottom surface of the thick large part of described belt pulley foundry goods arranges chill; Described rectangle emits belt wheel foundry goods outer wall top circumferencial direction described in opening's edge to be uniformly distributed; Described mold chill is evenly arranged on the bottom surface of described thick big belt pulley mold thick middle large part; Described circular cross-runner is connected with described belt pulley mold by described ingate.
Therein in an embodiment, have at least a described rectangle to emit cast model outer wall even circumferential described in opening's edge to distribute.
In an embodiment, have at least a described chill to be evenly arranged on the bottom surface of described thick big belt pulley mold thick middle real part position therein.
In an embodiment, described circular cross-runner is connected with described thick big belt pulley mold by ingate described at least one therein.
In an embodiment, described chill is rectangular-shaped therein.
The invention has the beneficial effects as follows: in the mold of the thick large part of foundry goods, be provided with chill, relatively accelerated the cooling velocity of thick large part between foundry goods outer wall and axis hole, Feeder Design above foundry goods outer wall along circumference, existing feeding effect, can slow down again the cooling velocity of belt wheel outer wall, makes foundry goods outer wall, thick middle real part position and position, axle hole Temperature Distribution are substantially even, cooling velocity is even, realizes and solidifying simultaneously, has reduced the casting stress in foundry goods.This device can the contraction of feeding foundry goods can regulate again Temperature Distribution in foundry goods, makes thick big belt pulley foundry goods almost there is no shrinkage and sink foundry goods, and axis hole crackle is eliminated.
Accompanying drawing explanation:
Fig. 1 is the structure top view of example 1 of the present invention;
Fig. 2 is the structure front view of example 1 of the present invention.
In figure: 1. ingate; 2. rectangle rising head; 3. chill; 4. axis hole; 5. circular cross-runner; 6. thick large belt wheel mold.
The specific embodiment:
Below in conjunction with accompanying drawing, the present embodiment is described further.
Refer to Fig. 1 and Fig. 2, the cast model of the thick large belt wheel porous dehiscence of a kind of supporting elimination line casting device providing for the preferred embodiment for the present invention, by described ingate 1, be connected with described circular cross-runner 5, the described axis hole 4 of described thick large belt wheel mold 6 of take is the center of circle, described rectangle is built rising head 2 and is arranged on described thick big belt pulley mold 6 outer walls tops along on its circumference outer ring, at the sand mold inner bottom surface of the thick large part of described belt pulley foundry goods, chill 3 is set.Have at least a described rectangle rising head 2 to be uniformly distributed along cast model outer wall top circumferencial direction, in mold, have at least a described chill 3 to be evenly arranged on the bottom surface of described thick big belt pulley mold 6 thick middle real part positions, described circular cross-runner 5 is connected with described thick big belt pulley mold 6 by ingate described at least one 1.
The thick large belt wheel porous dehiscence of above-mentioned elimination line casting device, in described mold by the thick large part of described foundry goods, be provided with described chill, relatively accelerated the cooling velocity of thick large part between described foundry goods outer wall and described axis hole, described rectangle rising head is located at described foundry goods outer wall top along circumference, existing feeding effect, can slow down the cooling velocity of described belt wheel outer wall again, make described foundry goods outer wall, thick middle real part position and position, described axle hole Temperature Distribution are substantially even, cooling velocity is even, realize and solidifying simultaneously, reduced the casting stress in described foundry goods.Can the contraction of feeding foundry goods can regulate again Temperature Distribution in foundry goods, make thick big belt pulley foundry goods almost there is no shrinkage and sink foundry goods, axis hole crackle is eliminated.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
