Abstract
The invention discloses an improved sand box for special-shaped parts. Through the improvement sand box for dysmorphism piece of above-mentioned optimal design, set up bearing structure at the sand box inner wall, support the lateral wall of opposite sex sand mould to the emergence that the sand mould lateral wall warp when avoiding the pouring effectively reduces the sand mould volume simultaneously, the use of the sand mould raw materials that significantly reduces. The invention also provides a sand casting assembly.
Description
Technical Field
The invention relates to the technical field of sand casting, in particular to an improved sand box for a special-shaped piece and a sand casting assembly.
Background
Sand casting is a widely used form of casting. The method comprises the steps of manufacturing a sand mould in advance, filling high-temperature-resistant particles into a gap between the sand mould and a sand box after the sand mould is placed in the sand box, supporting the side wall of the sand mould, and pouring molten metal into the sand mould.
When the special-shaped piece (such as a column product with a small top and a large bottom) is produced, the shape of the outer wall of the sand mold is also irregular due to the irregular shape of the mold cavity. During pouring, the space in the sand box needs to be filled with filling sand each time to support the side wall of the sand mould. However, this wastes resin sand, increasing the cost and reducing the productivity of workers.
Disclosure of Invention
To solve the technical problems in the background art, the invention provides an improved sand box and sand casting assembly for special-shaped pieces.
The invention provides an improved sand box for special-shaped pieces, which comprises: a box body;
the inside accommodation space that is equipped with open-top of box, accommodation space inside is equipped with the bearing structure who is used for supporting the sand mould outer wall.
Preferably, the support structure is formed of a support steel plate welded to an inner wall of the accommodating space.
Preferably, the end part of the supporting steel plate is welded and fixed with the inner wall of the accommodating space, and the middle part of the supporting steel plate is spaced from the inner wall by a preset gap.
Preferably, be equipped with the reinforcing steel plate in the predetermined clearance, reinforcing steel plate both ends respectively with the supporting steel plate with accommodation space inner wall connection.
Preferably, a plurality of reinforcing steel plates are arranged in the preset gap side by side.
According to the improved sand box for the special-shaped parts, the accommodating space with the top opening is formed in the box body, and the supporting structure for supporting the outer wall of the sand mould is arranged in the accommodating space. Through the improvement sand box for dysmorphism piece of above-mentioned optimal design, set up bearing structure at the sand box inner wall, support the lateral wall of opposite sex sand mould to the emergence that the sand mould lateral wall warp when avoiding the pouring effectively reduces the sand mould volume simultaneously, the use of the sand mould raw materials that significantly reduces.
The invention also provides a sand casting assembly, which comprises the improved sand box for the special-shaped piece.
Preferably, the sand mold is positioned in the accommodating space, the side wall of the sand mold is matched with the supporting structure, and filling sand grains are filled between the sand mold and the inner wall of the accommodating space.
In the present invention, the sand casting assembly is similar to the above-mentioned modified sand box for the special-shaped member in technical effect, and therefore, the description thereof is omitted.
Drawings
Fig. 1 is a schematic top view of an improved sand box for special-shaped parts according to the present invention.
Fig. 2 is a schematic view of a sand mold of an improved molding box for a profile member according to the present invention in the molding box.
Detailed Description
Fig. 1 is a schematic top view showing a modified flask for a profile member according to the present invention, and fig. 2 is a schematic inside view showing a sand mold of the modified flask for a profile member according to the present invention.
Referring to fig. 1 and 2, the present invention provides an improved sand box for special-shaped members, comprising: a box body 1;
the inside accommodation space that is equipped with open-top of box 1, accommodation space is inside to be equipped with the bearing structure who is used for supporting 2 outer walls of sand mould.
In order to explain the specific working conditions of the improved sand box for the special-shaped pieces in the embodiment in detail, the embodiment also provides a sand casting assembly which comprises the improved sand box for the special-shaped pieces.
Specifically, the sand casting assembly further comprises a sand mold 2, the sand mold 2 is located in the accommodating space, the side wall of the sand mold 2 is matched with the supporting structure, and sand filling particles 5 are filled between the sand mold 2 and the inner wall of the accommodating space. Wherein, the filling sand adopts resin sand mixed by sand, resin and curing agent.
In the specific work process of the improved sand box for the special-shaped part, firstly, a sand mould after mould closing is placed in the sand box, so that the inner wall and the supporting structure of the sand box are matched with the outer wall of the sand mould in shape, then, a gap at the periphery of the sand mould in the sand box is filled with sand, the supporting structure is guaranteed to support the outer wall of the sand mould through the sand, and finally, high-temperature metal liquid is poured into the sand mould through a pouring cup at the top of the sand mould, so that pouring of the special-shaped part is completed.
In this embodiment, the improved sand box for the special-shaped piece is provided with a top-opening containing space inside the box body, and a supporting structure for supporting the outer wall of the sand mold is arranged inside the containing space. Through the improvement sand box that is used for dysmorphism piece of above-mentioned optimal design, set up bearing structure at the sand box inner wall, support the lateral wall of opposite sex sand mould to the emergence of sand mould lateral wall deformation when avoiding the pouring effectively reduces the sand mould volume simultaneously, the use of the sand mould raw materials that significantly reduces, and reduce the use amount of the interior packing sand grain of sand box.
In the specific embodiment of the supporting structure, the supporting structure is formed by the supporting steel plates 3 welded on the inner wall of the accommodating space, the supporting structure is formed by the supporting steel plates, the processing is convenient, and the requirement on the supporting strength of the outer wall of the sand mould can be well ensured.
Further, 3 tip of supporting steel plate with accommodation space inner wall welded fastening and 3 middle parts of supporting steel plate with the clearance is predetermine at the inner wall interval, reduces and annotates the sand volume, reduces the invalid work of using of resin sand and resin sand equipment.
In a specific arrangement mode of the reinforced steel plates, the reinforced steel plates 4 are arranged in the preset gaps, and two ends of each reinforced steel plate 4 are respectively connected with the supporting steel plates 3 and the inner wall of the accommodating space; the support strength of the support steel plate is improved.
In a further embodiment, a plurality of reinforcing steel plates 4 are arranged in the preset gap side by side, and the shape-following steel plates are welded in the sand box according to the shape of the special-shaped piece, so that the supporting strength at different positions is ensured.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
