Description

Technical Field

[0001] This utility model belongs to the field of wax molds, and specifically relates to a split wax mold. Background Technology

[0002] For some long shaft-type workpieces, during the casting process, it is necessary to first manufacture a mold shell, and then inject the casting liquid through the mold shell opening to complete the casting of the workpiece. The mold shell manufacturing process involves multiple applications of slurry, sanding, and drying around the wax model, and then removing the wax model to complete the mold shell manufacturing. However, the size or shape of the sprue on the lower side of the mold shell will vary depending on the requirements of different products. However, all existing wax models are of a one-piece structure. When a mold shell with different sprues is required, the entire wax model needs to be replaced. The one-piece design has a limited range of adaptability during the processing, the mold processing cost is also high, and it will lead to low production efficiency. Therefore, it is necessary to design a split wax model to solve the above problems. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a split wax model, which solves the problem mentioned in the background art that existing wax models on the market are all one-piece and have a limited range of applications during processing.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A split wax model includes a long strip-shaped wax model body, in which a reinforcing rib is embedded. The upper end of the reinforcing rib is connected to the wax model body by a fixing nut, and a hollow split mold is threadedly connected to the outer side of the reinforcing rib above the fixing nut.

[0006] As a further improvement to this utility model, a plurality of reinforcing rings are uniformly fixed on the reinforcing rib.

[0007] As a further improvement to this utility model, a connecting nut is embedded at the bottom of the mold, a reinforcing plate is fixed in the middle of the outer wall of the connecting nut, and the connecting nut on the lower side of the reinforcing plate is threadedly connected to the upper end of the reinforcing rib.

[0008] As a further improvement to this utility model, the connecting nut on the upper side of the reinforcing plate is internally threaded with an umbrella-shaped hook.

[0009] As a further improvement to this utility model, the upper end cover of the mold is provided with a top cover, and the top cover has a through hole in the middle for easy passage of the umbrella handle-shaped hook. The outer side of the umbrella handle-shaped hook on the upper side of the top cover is threaded with a positioning nut, and the bottom side of the positioning nut abuts against the top cover.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model has a split mold connected by a threaded parting above the wax mold body, so that the entire wax mold forms a split structure. At this time, different wax mold bodies can be replaced below the parting mold. During production, the wax mold body can be replaced according to specific needs, which makes the wax mold more applicable, saves the cost of manufacturing wax molds, and effectively improves the production efficiency of products.

[0012] This invention improves the strength of the wax model body by embedding reinforcing ribs and reinforcing rings inside the wax model body, making it less prone to damage, especially when the wax model body is long.

[0013] This utility model prevents raw materials from entering the mold during product manufacturing by setting a top cover above the mold.

[0014] This invention facilitates the placement of the entire wax model by installing an umbrella-handle-shaped hook at the mold parting point. The umbrella-handle-shaped hook can be hung on the equipment, which is more convenient than placing it flat. Attached Figure Description

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] The present invention provides the following embodiments:

[0022] A split-type wax model includes a long strip-shaped wax model body 1. A reinforcing rib 2 is embedded within the wax model body 1. The upper end of the reinforcing rib 2 is connected to the wax model body 1 via a fixing nut 21. A hollow parting mold 3 is threadedly connected to the outer side of the reinforcing rib 2 above the fixing nut 21. This invention, by threading a parting mold 3 onto the upper part of the wax model body 1, creates a split-type structure for the entire wax model. Different wax model bodies 1 can be replaced below the parting mold 3. During production, the wax model body 1 can be changed according to specific needs, thus broadening the applicability of the wax model, saving manufacturing costs, and effectively improving product production efficiency.

By embedding the reinforcing rib 2 and reinforcing rings 22 in the wax model body 1, this utility model helps to improve the strength of the wax model body 1, especially when the length of the wax model body 1 is long, it is not easy to be damaged.

[0024] A connecting nut 4 is embedded at the bottom of the mold 3. A reinforcing plate 41 is fixed in the middle of the outer wall of the connecting nut 4. The connecting nut 4 on the lower side of the reinforcing plate 41 is threaded to the upper end of the reinforcing rib 2. The setting of the reinforcing plate 41 helps to fix the connecting nut 4 inside the mold 3.

[0025] The connecting nut 4 on the upper side of the reinforcing plate 41 is internally threaded with an umbrella handle-shaped hook 5; by installing the umbrella handle-shaped hook 5 at the mold parting 3, this utility model helps to place the entire wax model. The umbrella handle-shaped hook 5 can be hung on the equipment, which is more convenient than placing it flat.

[0026] The upper end of the mold 3 is provided with a top cover 6. The top cover 6 has a through hole 61 in the middle for easy passage of the umbrella handle-shaped hook 5.
