Abstract
The utility model discloses a wooden mold for forming a cast in molding sand. Steel liquid is poured in the cast to make cast steel in the shape of the wooden mold. The wooden mold comprises a bottom (1) consisting of a plurality of layers of wooden boards which are fixedly connected and a side surface (2) fixedly connected to the periphery of the bottom (1), wherein a die cavity (3) is composed of the bottom (1) and the side surface (2). The wooden mold has the following beneficial effects that the cast is formed in the molding sand of the wooden die; the steel liquid is poured in the cast to make the cast steel in the shape of the wooden mold, thus obtaining a DB mold; the wooden mold is easy to manufacture; and the labor and the resources are saved.
Description
Technical field
The utility model relates to mould, more particularly, relates to a kind of wooden model.
Background technology
In the process of making glass, can use a kind of concavo-convex steel part, generally be referred to as the DB mould.But when making the DB mould, be generally that a solid steel is hollowed out, polishes, make the DB mould.Therefore there is the defective of making difficulty, wasting time and energy in the DB mould of prior art.
The utility model content
The technical problems to be solved in the utility model is, makes defective difficult, that waste time and energy for the above-mentioned DB mould existence of prior art, and a kind of wooden model is provided.Wooden model of the present utility model has overcome defects, forms casting mold in molding sand with wooden model, and the cast molten steel is made the cast steel of wooden model shape in casting mold, namely gets the DB mould; Make simply, saved human and material resources.
The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of wooden model, be used for forming casting mold with described wooden model at molding sand, the cast molten steel is made the cast steel of described wooden model shape in described casting mold, described wooden model comprises by the affixed bottom surface that forms of plywood and is fixed in the side of described bottom periphery, and described bottom surface and side are formed with die cavity.
In wooden model described in the utility model, described wooden model also comprises for the bamboo nail of affixed described plywood and glue.
In wooden model described in the utility model, described bottom surface is lower arcuate surface.
In wooden model described in the utility model, the gap location of described plywood also is filled with atomized ash.
In wooden model described in the utility model, described side also is connected with extension.
Implement wooden model of the present utility model, have following beneficial effect: form casting mold in molding sand with wooden model, the cast molten steel is made the cast steel of wooden model shape in casting mold, namely gets the DB mould; Make simply, saved human and material resources.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in accompanying drawing:
Fig. 1 is the structural representation of the utility model wooden model embodiment;
Fig. 2 is along the cutaway view of A-A line in Fig. 1;
Fig. 3 is along the cutaway view of B-B line in Fig. 1.
The specific embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast accompanying drawing and describe the specific embodiment of the present utility model in detail.
As shown in Figure 1-Figure 3, the wooden model of the present embodiment is used for forming casting mold with wooden model at molding sand, and the cast molten steel is made the cast steel of wooden model shape in casting mold, wooden model comprises by the affixed bottom surface that forms 1 of plywood and is fixed in the side 2 of bottom surface 1 periphery, and bottom surface 1 and side 2 are formed with die cavity 3.Bottom surface 1 is lower arcuate surface, and lower arcuate surface is along the direction bending away from die cavity 3.Side 2 also is connected with extension 4, and in the present embodiment, the quantity of extension 4 is 6, and certainly, the quantity of extension 4 is not limited to 6, can be also other quantity as 3,8 etc.
Plywood adopts bamboo nail and glue to carry out affixed.The gap location of plywood also is filled with atomized ash.Atomized ash is commonly called as putty, claims again unsaturated polyester resin putty, and the effect of filling atomized ash is to make the junction of plywood smooth.
Further:
The first, the key of design wooden model is to calculate accurately the washing shrinkage of cast steel, contrast by experiment, and the discovery washing shrinkage will be made corresponding adjustment according to the wall thickness of product.
At length say, correspondingly, cast steel comprises cast steel bottom surface, cast steel side and cast steel die cavity;
The length of cast steel side is greater than one meter, and the shrink ratio of the wall thickness of cast steel side is 0.398; The length of cast steel side is less than or equal to one meter, and the shrink ratio of the wall thickness of cast steel side is 0.333;
The shrink ratio of cast steel bottom surface is 0.018;
The length of cast steel inner chamber is greater than one meter, and the shrink ratio of cast steel inner chamber is 0.45; The length of cast steel inner chamber is less than or equal to one meter, and the shrink ratio of cast steel inner chamber is 0.413;
The shrink ratio of the opening part of cast steel die cavity is 0.028.
The second, plywood carries out affixed with bamboo nail and glue, with Digit Control Machine Tool, plywood is processed after doing.
The 3rd, then carry out fine finishining with Digit Control Machine Tool.
The 4th, check, packing.The wooden model that processes is carried out layout inspection, repair with atomized ash connecting uneven the other side.The receiving party that packing process will be considered timber to, guarantee that in transportation, wooden model can not damage.
The above is described embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, also can make a lot of forms, within these all belong to protection of the present utility model.
