Abstract
The utility model discloses a large casting gating system belongs to the casting technique, if the workshop direction of height space is not enough during the production of large casting, can't produce the pouring, the utility model discloses install the sand box of passing a bridge in the side of main sand box and the top surface of passing a bridge the sand box is not higher than the top surface of main sand box to with the high reduction of runner basin, leave sufficient space in the top of runner basin, make the pouring opening of ladle can be higher than the runner basin and pour into a mould. Moreover, a gap bridge sand box and a pouring basin are arranged on two opposite sides of the main sand box; two traveling cranes are used for respectively hoisting a ladle and simultaneously pouring the pouring basins on the two sides, so that the ladle with a short height and a small capacity can be used for pouring large castings, the pouring opening of the ladle is higher than the pouring basin, the product quality is ensured, and the pouring efficiency is improved.
Description
Technical Field
The utility model belongs to the casting technique, concretely relates to large-scale foundry goods gating system is applicable to large-scale foundry goods height very high, the manufacturing under the high space restricted condition in workshop during the pouring.
Background
In a general foundry, for pouring large castings (such as castings of more than 40 tons), it is important to ensure that an effective space exists in the height direction of a workshop, and if the space in the height direction of the workshop is insufficient, pouring cannot be performed.
The pouring basin of the existing pouring system is directly placed on the cover box, or the gap bridge sand box is installed on the cover box, and then the pouring basin is placed on the gap bridge sand box, so that the whole height of the pouring system is too large, and the pouring opening of the ladle is lower than the pouring basin on the premise that the effective space in the height direction of a workshop is set, and pouring cannot be carried out.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that solve and the technical task that provides are that workshop direction of height space is not enough when overcoming the large-scale foundry goods of production, can't produce the defect of pouring, provide a large-scale foundry goods gating system.
In order to achieve the above object, the utility model discloses a large casting gating system, be in including main sand box, packing molding sand in the main sand box, gap bridge sand box, install runner basin on the gap bridge sand box, form die cavity, characterized by in the molding sand: the gap bridge sand box is arranged on the side surface of the main sand box, and the top surface of the gap bridge sand box is not higher than that of the main sand box.
As a preferable technical means: the main sand box comprises a bottom box, at least one sand box ring and a cover box which are sequentially stacked together from bottom to top, the gap bridge sand box is arranged on the side surface of the cover box, and the top surface of the gap bridge sand box is not higher than that of the cover box.
As a preferable technical means: the two opposite sides of the main sand box are provided with the gap bridge sand box and the pouring basin.
As a preferable technical means: and a sprue, an ingate and a cross gate are arranged in the molding sand in the main sand box.
The utility model discloses install the sand box of passing a bridge in the side of main sand box and the top surface of sand box of passing a bridge not be higher than the top surface of main sand box to with the high reduction of runner basin, leave sufficient space in the top of runner basin, make the pouring opening of ladle can be higher than the runner basin and pour into a mould.
Moreover, a gap bridge sand box and a pouring basin are arranged on two opposite sides of the main sand box; the two traveling cranes can respectively hoist a ladle to simultaneously pour the pouring basins on the two sides, so that the pouring efficiency is improved, the ladle with a short height and a small capacity can be used for pouring large castings, the pouring opening of the ladle is higher than the pouring basin, and the product quality is ensured.
Drawings
FIG. 1 is a schematic view of a large casting gating system of the present invention;
the reference numbers in the figures illustrate: 01 main sand box, 1 ladle, 2 pouring basin, 3 sprue, 4-bridge-crossing sand box, 5-cavity, 6-cover box, 7-sand box ring, 8-bottom box, 9-ingate, 10-cross gate, 11-crane hook and 12-molding sand.
Detailed Description
The present invention will be further explained with reference to the drawings attached to the specification.
The large casting pouring system shown in fig. 1 comprises a main sand box 01, molding sand 12 filled in the main sand box, a gap bridge sand box 4 and a pouring basin 2 installed on the gap bridge sand box, wherein the main sand box 01 comprises a bottom box 8, a plurality of sand box rings 7 and a cover box 6 which are sequentially stacked together from bottom to top, a cavity 5 is formed in the molding sand, the gap bridge sand box 4 is installed on the side surface of the cover box 6, and the top surface of the gap bridge sand box 4 is not higher than the top surface of the cover box 6. A sprue 3, an ingate 9 and a cross runner 10 which are communicated with the sprue basin 2 and the cavity 5 are arranged in the molding sand of the main sand box 01. As shown in the figure, the height of the top surface of the cover box 6 is H, the height of the pouring opening of the ladle 1 is H, and the height of the upper edge of the pouring basin 2 is H1, so that H1= H is limited, thereby achieving the purpose of lowering H1 to enable H1 to be less than H, and thus, a sufficient space is left above the pouring basin 2 to enable the pouring opening of the ladle to be higher than the pouring basin for pouring.
The pouring height can be reduced by the aid of the large casting pouring system. Moreover, in order to improve the pouring efficiency, the bridge sand box 4 and the pouring basin 2 are arranged on two opposite sides of the cover box 6 of the main sand box 01. Two traveling cranes are used for respectively hoisting a ladle 1 and simultaneously pouring the pouring basins 2 on the two sides, the ladle with a short height and a small capacity can be used for pouring large castings, the pouring opening of the ladle is higher than the pouring basin, and the product quality is ensured.
