Abstract
The utility model relates to a kind of Anti-cracking wooden model core box, belongs to the technical field of wooden model for casting.It comprises core box matrix, and described core box matrix is formed with curved bottom portion, and described curved bottom portion top is provided with the curved face part of being made by monoblock offset plate, between curved face part and curved bottom portion, by spaced wooden unit, supports.It can effectively solve wooden model core box cracking, thereby distortion affects a casting accuracy difficult problem.
Description
Technical field
The utility model relates to a kind of Anti-cracking wooden model core box, belongs to the technical field of wooden model for casting.
Background technology
Wooden model is that casting industry is used mould widely, wooden model core box has inner sunken face, especially medium caliber and bigbore core box, surface area is larger, in industry, be to adopt batten splicing method at present, surface joining is formed, with the produced core box of the method, it is the general mould of casting unit, through the use of 5 years of center Su Faheng shop Machinery Co., Ltd., find, there is following defect in this product: 1, such core box is used 2 ~ 3 months substantially, shrinkage porosite due to timber, will crack, be used for splicing the timber meeting perk distortion of curved surface, cause mould repair work to increase, especially can affect product size precision, enterprise is caused to a large amount of cost allowances, 2, with timber, be spliced into curved surface, to take timber too many, production process is complicated, Production Time is long, affects manufacturing schedule.
Summary of the invention
Thereby the utility model object is to provide a kind of can effectively solve wooden model core box cracking, be out of shape the Anti-cracking wooden model core box that affects a casting accuracy difficult problem, solved the shrinkage porosite due to timber that existing wooden model core box exists, will crack, be used for splicing the timber meeting perk distortion of curved surface, cause mould repair work to increase, especially can affect product size precision, enterprise is caused to a large amount of cost allowances; With timber, be spliced into curved surface, to take timber too many, production process is complicated, Production Time is long, affects the problems such as manufacturing schedule.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises core box matrix, described core box matrix is formed with curved bottom portion, described curved bottom portion top is provided with the curved face part of being made by monoblock offset plate, between curved face part and curved bottom portion, by spaced wooden unit, supports.Described offset plate is wood glue plate or bamboo offset plate.By the produced curved face part of offset plate of a full surface, smooth surface, nothing splicing trace, the core surface quality of producing is good, and precision is reliable; Significantly reduced the timber use amount in former technique, one side reduces process time, processing cost, has reduced on the other hand the generation of the defects such as the crackle being caused by timber shrinkage porosite, surperficial perk, has effectively reduced maintenance cost and the maintenance time of mould; For ease of maintenaince, if curved surface damages, ground floor offset plate can be changed, maintenance load is little, and changes the core box of making old technique, needs the timber of splicing to change, and what face is the maintenance of large workload.
As preferably, described curved face part is laminated by some layers of offset plate, thereby improves intensity and the reliability of curved face part, is also convenient in addition the maintenance of curved face part, only the offset plate on top layer need be removed and change new offset plate during curved face part damaged surfaces.
As preferably, between described some layers of offset plate, by steel nail, interfix, thereby improved glue plate layer fixing reliability each other.
As preferably, described wooden unit is the little cone-like structure of the large upper end cross sectional of lower end cross-sectional area.Adopt the wooden unit lower end of cone-like structure to form reliable connection with curved bottom portion, the less sectional area in wooden unit upper end can reduce the contact area of wooden unit and offset plate lower surface, guarantees the curved surface smoothness of curved face part.
As preferably, the two ends end face of described curved bottom portion is coated with cover plate, described cover plate extends to formation elongated end in curved bottom portion, described curved face part is laminated by some layers of offset plate, the top layer offset plate gland of curved face part is at the end face of cover plate elongated end, and the end face of the offset plate below curved face part top layer is connected to the lower surface of cover plate elongated end.Wherein, curved face part top layer offset plate gland can guarantee the smooth and smooth of curved face part surface at the end face of cover plate elongated end, the lower surface that the end face of the offset plate below curved face part top layer is connected to cover plate elongated end can prevent the perk at curved face part two ends the distortion of restricted curved surface portion, guarantee the stability of curved face part, improved the Forming Quality of sand mold.
Therefore, thus the utlity model has can effectively solve wooden model core box cracking, distortion affects the features such as a casting accuracy difficult problem.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the utility model wooden model core box;
Fig. 2 is the A place partial enlarged drawing of Fig. 1.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, core box matrix 1 is formed with curved bottom portion 2, and curved bottom portion 2 tops are provided with the curved face part 3 of being made by monoblock wood glue plate or bamboo offset plate.Between curved face part 3 and curved bottom portion 2, by spaced wooden unit 4 supportings, wooden unit is the little cone-like structure of the large upper end cross sectional of lower end cross-sectional area.The utility model does not adopt timber splicing legal system to make curved surface, but the disposable curved surface of producing of adoption of innovation wood glue plate or bamboo offset plate, by steel nail, increase the offset plate number of plies again, thickness is increased to 15-20mm, between offset plate curved surface and core box matrix, adopts the flitch of 4x6mm to support, this technique has the following advantages: by the produced curved surface of offset plate of a full surface, smooth surface, nothing splicing trace, the core surface quality of producing is good, and precision is reliable; Significantly reduced the timber use amount in former technique, one side reduces process time, processing cost, has reduced on the other hand the generation of the defects such as the crackle being caused by timber shrinkage porosite, surperficial perk, has effectively reduced maintenance cost and the maintenance time of mould; For ease of maintenaince, if curved surface damages, ground floor offset plate can be changed, maintenance load is little, and changes the core box of making old technique, needs the timber of splicing to change, and what face is the maintenance of large workload.As shown in Figure 2, the two ends end face of curved bottom portion 2 is coated with cover plate 5, cover plate 5 extends to formation elongated end 6 in curved bottom portion, curved face part 3 is laminated by multilayer offset plate, between multilayer offset plate, by steel nail, interfix, top layer offset plate 7 glands of curved face part are at the end face 9 of cover plate elongated end 6, and the end face of the offset plate 8 below curved face part top layer is connected to the lower surface 10 of cover plate elongated end.Curved face part top layer offset plate gland can guarantee the smooth and smooth of curved face part surface at the end face of cover plate elongated end, the lower surface that the end face of the offset plate below curved face part top layer is connected to cover plate elongated end can prevent the perk at curved face part two ends the distortion of restricted curved surface portion, guarantee the stability of curved face part, improved the Forming Quality of sand mold.
