As shown in fig. 5, in the drag box 32 obtained by disposing molding sand in the lower mold 22, a flange cavity 322 corresponding to the flange pattern 222, a first cylinder cavity 323 corresponding to the first cylinder pattern 223, a lower core cavity 324 corresponding to the lower core pattern 224, and a runner 327 corresponding to the runner pattern 227 are formed. The flange cavity 322 and the runner 327 are recessed from the parting plane of the drag 32 toward the bottom surface of the drag 32.
Accordingly, as shown in fig. 6 to 9, the first cylinder chamber 323 is disposed at the bottom end of the flange chamber 322, and the lower core chamber 324 is disposed at the bottom end of the first cylinder chamber 323. The flange cavity 322, the first barrel cavity 323, and the lower core head cavity 324 are in communication with one another, which together define the lower cavity 302.
After the cope and drag molds are closed, the lower cavity 302 faces the upper cavity 301, and the runner 327 faces the sprue 317. Meanwhile, a hub core 33 is arranged in a cavity formed by the upper cavity 301 and the lower cavity 302, the upper end and the lower end of the hub core 33 are respectively matched in the upper core cavity 314 and the lower core cavity 324, and the outer peripheral surface of the hub core 33 is spaced from the inner peripheral surfaces of the flange cavity 322, the first cylinder cavity 323, the second cylinder cavity 312 and the third cylinder cavity 313, so that the cast workpiece is in a hollow stepped cylinder shape. At the same time, a certain gap is formed between the upper core head cavity 314 and the lower core head cavity, so that the gas in the cavity can enter the gas outlet 315 through the gap.
In an embodiment of the present disclosure, a boss 3241 is disposed on one side of a bottom surface of the lower core cavity 324, and a notch 331 corresponding to the boss 3241 is correspondingly disposed at a bottom end of the hub core 33 to cooperate with the boss 3241 for limiting, so as to prevent the hub core 33 from moving circumferentially or radially in the cavity due to molten iron impact during casting.
At the same timeReferring to fig. 10-12, the accommodating chamber 3161 also accommodates the easy separation plate 34. The easy separation piece 34 is located at the bottom of the cope 31, and the bottom surface thereof abuts against the parting surface of the drag 32. A riser socket 342 facing the riser 3162 and a riser neck 341 communicating the riser socket 342 with the second body cavity 312 are provided in the frangible web 34. The riser socket 342 and the riser neck 341 together form a feeding channel. The feeding channel faces the bottom periphery of second chamber 312. The flange 15, the first cylinder 11, the second cylinder 12 and the third cylinder 13 correspond to each other in the dimensional relationship R15>R12>R13≈R11Wherein is R15Radial dimension, R, of the flange 1511Is the radial dimension, R, of the first cylinder 1112Is the radial dimension, R, of the second cylinder 1213Is the radial dimension of the third cylinder 13. Therefore, in the casting process, the largest hot spot of the casting is located at the junction of the flange 15 with the largest radial dimension and the second cylinder 12, namely the periphery of the bottom of the second cylinder cavity 312 opposite to the feeding channel, and the arrangement of the easy spacer 34 can enable the riser 3162 to feed the hot spot, so that the feeding efficiency of the hot spot is improved, the feeding amount is reduced, the internal quality of the hot spot is ensured, and the problem that the internal quality defects such as shrinkage porosity and shrinkage cavity are easily generated in a hot spot area in the related technology is solved.
The end surface of the easy separation plate 34 facing the second cylinder chamber 312 is an arc surface with the same inner circumferential surface of the second cylinder chamber 312, so that the radian of the surface of the cast second cylinder 12 facing the easy separation plate 34 is the same as that of the other positions. Meanwhile, the cross-sectional dimension of the riser neck 341 is reduced along with the distance from the riser socket 342, so that the flow rate of molten iron is accelerated, and the whole cavity can be rapidly filled with the molten iron.
In some embodiments of the present disclosure, the bottom surface of the septum 34 is further provided with a downwardly projecting positioning projection 346. The positioning protrusions 346 are inserted into the drag mold 32 to position the break away piece 34 and secure the break away piece 34.
The frangible web 34 also has a riser patch 343 at the end of the riser neck 341 remote from the riser nest 342 to extend the effective feeding distance of the risers 3162. The riser patch 343 communicates the riser neck 341 with the second barrel cavity 312, the cross-sectional dimension of the riser patch 343 is larger than that of the riser neck 341, and the distance between both side surfaces of the riser patch 343 is increased as being away from the interface 344 with the riser neck 341 to ensure that molten iron in the cavity is sequentially solidified, enhancing the feeding effect.
Specifically, the interface 344 between the riser patch 343 and the riser neck 341 is a sloped surface sloping toward the bottom and inside of the frangible web 34, and the interface 344 is provided with an opening 345 communicating the riser patch and the riser neck to form a fracture surface in the casting corresponding to the interface 344. The casting can be broken and separated from the riser part along the fracture surface by knocking with a hammer, so that the step of cutting the casting after casting in the traditional process is omitted, and the working hours and the labor force are saved. While the width of the top of the opening 345 is smaller than the width of the bottom thereof to further ensure that the fracture surfaces can be separated more easily.
In some embodiments of the present disclosure, to improve the efficiency of casting, multiple cavities may be provided in a molding box, which are symmetrical about a runner and communicate with the same gate through the runner. In the present disclosure, four cavities are provided in one molding box as an example.
In the embodiment of the present disclosure, the gate 3172 is located in the middle of the cope 31. The runners 327 in the drag 32 include a main runner 3272 opposite the gate 3172 and a secondary runner 3271 extending from the main runner 3272 to either side. The middle section of the main runner 3272 is recessed downward to form a groove, and the groove and the buffer cavity 3171 together form a buffer space to control the flow rate of molten iron entering the runner 327 from the gate 3172. The four cavities are distributed on two sides of the runner 327 and are communicated with the sub-runner 3271. Two easy-to-separate sheets 34 in the casting mold 3 are respectively placed between two cavities on the same side, and the cavities at two ends of the easy-to-separate sheets 34 are communicated with the riser sockets 342 through two riser necks 341 on the easy-to-separate sheets 34, so that one riser can feed a plurality of cavities, and further casting materials are saved.
The above description is only for the purpose of illustrating the preferred embodiments of the present disclosure and is not to be construed as limiting the scope of the present disclosure, but rather is intended to cover all equivalent structural changes made by applying the teachings of the present disclosure to the accompanying drawings.
