[0025] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only."

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] See also Figures 2 to 4 , a schematic diagram of a casting tree group structure shown in an embodiment of the utility model. Figure 1 As shown, it includes a tree group body 1 and a wax model 2, the tree group body 1 includes a casting port 11 and a plurality of casting trunks 12; a plurality of wax model connecting parts 121 are provided on both sides of the casting trunks 12, and the wax model connecting parts 121 between each of the casting trunks 12 are staggered according to the structural size of the wax model 2; the wax model 2 is fixedly connected to the wax model connecting parts 121.

[0029] In this embodiment, the tree group trunk 1 and the wax model 2 are both made of wax material. By cross-displacement of the wax model connection parts 121 between each casting tree trunk 12, the space idle rate is reduced and the space utilization rate of the casting tree group is improved. Wax model connection parts 121 are set on both sides of the casting tree trunk 12 so that casting can be carried out simultaneously on the casting tree trunk 12. It can be understood that the wax material tree group can be coated with fireproof material on its outer surface by dipping it in slurry and sprinkling sand, and then repeatedly dewaxing it at high temperature after multiple layers of production to obtain a hollow shell mold structure with a cavity structure for molten steel casting.

[0030] In some embodiments, Figure 4 As shown, the wax mold connection portion 121 is in an "L" shape or a "J" shape, so as to extend the casting trunk 12 laterally, thereby improving the lateral space utilization of the casting tree group.

[0031] In some embodiments, Figure 2 or Figure 3 As shown, the wax mold 2 is laterally fixedly connected to the wax mold connecting portion 121, thereby improving the lateral space utilization rate of the casting tree group.

[0032] In some embodiments, Figure 5 and Figure 6 As shown, both sides of the wax model connection part 121 are provided with a plurality of first connection members 1211, and all the first connection members 1211 on each side are correspondingly fixedly connected with all the second connection members 21 of a wax model 2. One side of a wax model connection part 121 is connected to a wax model 2, and one side of a wax model connection part 121 is provided with a plurality of first connection members 1211, such as Figure 6 Two wax model connection ports are shown; accordingly, the wax model 2 is provided with a plurality of second connection members 21 connected to the first connection member 1211 .

[0033] Alternatively, if Figure 6 As shown, the first connecting member 1211 is a boss-shaped wax model connecting member extending outward from the wax model connecting portion 121 , and the boss-shaped wax model connecting port is cylindrical or square.

[0034] In some embodiments, Figure 6 As shown, the connection between the first connecting member 1211 and the second connecting member 21 is an inwardly concave "V" shape 1212, so that it can be broken and fallen off by vibration. At the same time, when the wax model is arranged horizontally, the vibration-breaking force area of ​​the wax model is larger, thereby achieving automatic vibration breaking and falling off.

[0035] In some embodiments, Figure 7As shown, a trunk connector 122 is also provided between the plurality of casting trunks 12. The trunk connector 122 enables the empty shell mold structure to continue to transport the molten liquid in the casting pipe, and ensures the stability of the casting pipe to avoid shaking during the casting process.

[0036] In some embodiments, Figure 7 As shown, one of the casting trunks 12 is also provided with a casting trunk outlet 123, and the position of the casting trunk outlet 124 is lower than the lowest position of the other casting trunks. The casting trunk outlet 123 can discharge the air in the pipeline and recover the excess molten liquid, and only one outlet is required, which is convenient for the recovery of the molten liquid.

[0037] In some embodiments, Figure 7 As shown, auxiliary trunks 13 communicating with the casting trunk 12 are also provided on both sides of the casting port 11. Through the auxiliary trunks 13, the hollow shell mold structure can accelerate the molten liquid to evenly enter the casting pipe, thereby improving the casting efficiency.

[0038] By way of example and not limitation, Figures 1 to 7 As shown, the second connecting pieces 21 of the wax mold 2 are correspondingly and staggeredly bonded to the first connecting pieces 1211 of the corresponding wax mold connecting parts 121 to form a tree group structure composed of wax material. The wax material tree group is coated with fireproof material on its outer surface by slurry and sanding, and high-temperature dewaxing is performed after repeated multi-layer production to obtain a hollow shell mold structure with a cavity structure. The molten steel is poured into the casting port of the hollow shell mold structure, and the casting tree corresponding to the hollow shell mold structure pours the molten steel to each wax mold position corresponding to the hollow shell mold structure. After the hollow shell mold wax mold is filled with molten steel, it is cooled. When the hollow shell mold wax mold is cooled to a specified temperature, the casting tree group is vibrated by a vibrating machine so that the hollow shell mold wax mold is automatically vibrated and falls off, and then the hollow shell mold is peeled off to obtain the casting in the hollow shell mold, thereby completing the casting.

[0039] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
