In order to realize the purpose, the utility model discloses a technical scheme is:
a circular steel casting mould comprises a reverse mould box and a sand box, wherein the reverse mould box is matched with the sand box to perform reverse mould forming on a gear, a cast gear mould is arranged in the reverse mould box, the reverse mould box is supported by cast steel, the cross section of the reverse mould box is circular, the outer diameter of the cast gear mould is smaller than the inner diameter of the reverse mould box, the difference between the inner diameter of the reverse mould box and the outer diameter of the cast gear mould is the thickness of the cast gear, the sand box is arranged on the top side of the reverse mould box and is in sealed buckling connection, a sprue cup communicated with the inner side of the sand box is arranged at the top of the sand box, the sand box is buckled above the reverse mould box, then molten steel is poured inwards through the sprue cup at the top of the sand box, and the pouring molten steel keeps slow frequency, molten steel can flow into the mould box of falling along the pouring basin elder generation and then stretch and fill, later can be full of inside mould box and the sand box of falling, cooling shaping at last, only be provided with a bore pouring basin that is bigger a little because of the sand box top, a pouring basin plays into molten steel and carminative effect simultaneously, thereby can abandon the gas outlet, need not set up other holes that are used for giving vent to anger at the sand box, thereby can not extend because of the venthole and have the lug pouring thick circular steel casting, and avoided need cut the lug after the mould shaping of falling, increase work load and extravagant molten iron, can not influence the pleasing to the eye of steel casting simultaneously yet, practical effect has been increased.
Further, the cast gear mold is composed of a plurality of mold lugs, the mold lugs are arranged in sequence to form a circle, gaps are reserved among the mold lugs in sequence, so that the flow direction of internal gas for pouring molten steel is smooth, air holes cannot be formed in the mold lugs, the internal gas can be gathered towards the middle along gaps among the mold lugs during pouring and then is discharged through the sprue cup, the molten steel can effectively and smoothly flow to the outer sides of the mold lugs through the gaps under the cooperation of the mold lugs, the gaps are provided with a plurality of gaps, therefore, the molten steel cannot be blocked due to pressure intensity problems, meanwhile, the gaps are filled with the molten steel to form supporting rods for reinforcing and supporting the inner side of the steel casting, the bottoms of the mold lugs are fixed at the bottom of the inner side of the inverted mold box, when the sand box is buckled on the inverted mold box, the tops of the mold lugs are attached to the top side of the inner side of the sand box, the molten steel can be shunted through the mold lugs, and further through holes among the supporting rods in the circular steel casting are formed, so that the quality of the steel casting is reduced and the molten steel is saved.
Further, the mould lug is provided with four groups at least.
Furthermore, an inner control column is fixed in the middle of the inverted mould box, the diameter of the inner control column is smaller than the caliber of the inlet of the pouring cup, the inner control column is located at the center of the cast gear mould, and the inner control column is mainly used for filling space to enable molten steel to form an inner hole in the middle of a circular steel casting.
Furthermore, the two sides of the mold stripping box are provided with the movable handles, so that workers can conveniently hold the mold to move.
Compared with the prior art, the utility model beneficial effect shows:
the utility model discloses only set up a bore at the sand box top and slightly greater pouring cup, abandoned the venthole among the prior art in the circular casting mould, and then pour and accomplish thick circular steel casting and can not extend because of the venthole and have the lug, avoided in addition needing to cut the lug after the back mould shaping, increase work load and extravagant molten iron, also can not influence the pleasing to the eye of steel casting simultaneously, increased practical function.

Detailed Description
For the convenience of understanding of those skilled in the art, the technical solution of the present invention will be further specifically described with reference to fig. 1 to 3.
The utility model discloses, a circular steel casting mould, including inverted mould case 1 and sand box 2, inverted mould case 1 cooperation sand box 2 is used for carrying out the inverted mould shaping to the gear, be provided with cast gear mould 11 in the inverted mould case 1, inverted mould case 1 is supported by the cast steel, and its cross section is ring shape, cast gear mould 11 external diameter is less than inverted mould case 1 internal diameter to the difference of inverted mould case 1 internal diameter and cast gear mould 11 external diameter is the thickness of cast gear promptly, inverted mould case 1 middle part is fixed with interior accuse post 12, interior accuse post 12 diameter is less than the bore that pouring cup 13 was imported to interior accuse post 12 position cast gear mould 11 central point, interior accuse post 12 mainly used for fills the space, makes the hole at the circular steel casting middle part of molten steel shaping, sand box 2 sets up in inverted mould case 1 top side and leakproofness lock joint, 2 tops of interior accuse are provided with pouring cup 13 of its inboard, is going on to pouring sand box 2 top in inverted mould case 1 top, then through pouring cup 13 to interior pouring cup lock joint, pouring box is provided with the convenient removal of the hand and is held the sand box 3 people's.
When the pouring molten steel keeps slow frequency, the molten steel can flow into the inverted mould box 1 along the pouring cup 13 firstly and then spread and fill, then the inverted mould box 1 and the sand box 2 can be filled with the molten steel, and finally cooling and forming are carried out, only the pouring cup 13 with a slightly larger caliber is arranged at the top of the sand box 2, and one pouring cup 13 plays roles of feeding the molten steel and exhausting simultaneously, so that a gas outlet can be abandoned, other holes for discharging gas are not required to be formed in the sand box 2, and a convex block can not extend due to the gas outlet when a thick circular steel casting is poured, and the convex block is prevented from being cut after the inverted mould forming, so that the workload and the waste of the molten steel are increased, meanwhile, the attractiveness of the steel casting is not influenced, and the practical effect is increased.
