Embodiment 1

[0053] Such as Figure 1-11 As shown, a vertical series casting mold for steel castings includes a bottom plate 1 and a cover plate 6. The bottom plate 1 and the cover plate 6 are fixed by bolts 5 to form a casting cavity, and a casting module is arranged in the casting cavity.

[0054] The casting module includes a bottom block 2, a middle block 3, and an upper block 4. The bottom block 2 is arranged at the bottom of the casting cavity, the upper block 4 is arranged at the top layer of the casting cavity, and several medium blocks 3 Set between the bottom block 2 and the upper block 4. The bottom block 2 has a groove in the middle, and a casting structure is provided around it. The middle block 3 is a through hole, and there are several casting structures around it. Each casting structure is provided with a through hole, and the upper block 4 is provided in the middle. There is a through hole, and a casting structure is provided around it.

[0055] The bottom block 2, the middle...

Embodiment 2

[0058] Example 2 is basically the same as Example 1, but the difference is that the bottom block, medium block, and upper block are formed in series with a vertical runner in the middle. The runner mouth of the vertical runner can be designed from top to bottom. The lower diameter gradually increases, because the lower the casting, the greater the pressure difference between the inside and the outside, the larger the diameter can reduce the pressure, and the upper and lower pressure differences between the inside and outside ensure a balance. The casting increases smoothly when the casting is downward. Better efficiency, faster speed, guarantee product accuracy and casting efficiency. In this way, the groove of the bottom block is larger than the through hole of the upper block, and the through hole of the medium block gradually increases from top to bottom; when the product is cast, it can also ensure that the bottom connection is thicker, and it is not easy to cause the connec...

Embodiment 3

[0060] Embodiment 3 is basically the same as embodiment 1 or 2, the difference is that the bottom block, medium block, and upper block are located away from the center according to requirements, that is, the closer the casting structure is to the edge, the size is required Gradually increase in size. According to the casting characteristics of different castings, choose different enlargement coefficients. The increase coefficient is between 0.05% and 0.3% of the original size basis. The thickness of the sand coating during casting can also be gradually reduced to reduce the coefficient. Between 0.05%-0.3% of the original size. Because it is far away from the center, the inflowing casting material flows more slowly, and the pressure is reduced, and the corresponding size is gradually enlarged, which effectively ensures the consistency of the end surface level. The rate of good products increases, and the rate of good products can rise by more than 20%.

Abstract

The invention discloses a vertical cluster casting die for cast steel parts and a cluster casting method thereof, and belongs to the field of metal part casting. The vertical cluster casting die for the cast steel parts and the cluster casting method thereof aim to solve the problems that in the prior art, the number of procedures is large, the period is long, the productivity is low, the cost is high, the product quality stability is poor, and the product qualification rate is low. The vertical cluster casting die comprises a bottom plate and a cover plate, wherein the bottom plate and the cover plate are fixed through bolts to form a casting cavity, and a casting module is arranged in the casting cavity; and the casting module comprises a bottom block, middle blocks and an upper block, a groove is formed in the middle of the bottom block, casting structures are correspondingly arranged on the periphery of the bottom block, a through hole is formed in the middle of each middle block, a plurality of casting structures are arranged on the periphery of each middle block, a through hole is formed in each casting structure, a through hole is formed in the middle of the upper block, and casting structures are correspondingly arranged at the periphery of the upper block. According to the vertical cluster casting die for the cast steel parts and the cluster casting method thereof, the number of procedures is small, the period is short, the productivity is high, the cost is low, the product quality stability is high, and the product qualification rate is high.

Description

Technical field [0001] The invention relates to the field of metal castings, and more specifically, to a vertical series casting mold for steel castings and a series casting method thereof. Background technique [0002] Gear sleeve type wear-resistant castings are small steel castings with a unit weight of 1-10 kg. Most of the existing technology is produced by the precision casting method (lost wax method). Although this method has the advantages of high dimensional accuracy and beautiful appearance, it has a long production cycle, serious environmental pollution, high cost, and high labor intensity of workers. Precision casting (lost wax method) uses natural wax material or synthetic wax material, presses it into a casting shape in a mold, and then assembles it into a tree, and then the tree invades the paint to moisten it and hang the sand, immerse it in a curing agent to cure, and so on. Hang 11-17 sands, the larger the casting, the more layers of hanging sand; after the han...
