Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a quick-assembly and disassembly device for the inner mold of a molten iron ladle. Background Technology

[0002] This mold is mainly used for casting the refractory lining of molten iron ladles. The mold is 2 meters high. Because it is difficult to remove the mold after the external refractory material has solidified, it is designed as a detachable upper and lower part. It must be assembled before each use and disassembled when removing the mold. The mold is a cylindrical barrel shape, wider at the top and narrower at the bottom, connected internally by bolts. Each time it is used, workers must enter the mold to connect the bolts, and once connected, it is difficult for workers to get out.

[0003] The main improvement of this utility model is that the bolt connection is changed to a long connecting rod connection, so that workers do not need to enter the mold and can operate from the top, reducing the difficulty of operation and lowering the safety risks. Utility Model Content

[0004] The purpose of this invention is to provide a quick-assembly and disassembly device for the inner mold of a molten iron ladle, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-assembly and disassembly iron ladle inner mold device, comprising an upper mold and a lower mold, wherein multiple corresponding slots are respectively provided in the upper mold and the lower mold, and a connecting rod is inserted into each set of slots. The two ends of the connecting rod are detachably fixed to the top of the upper mold and the bottom of the lower mold, respectively. The upper mold and the lower mold fit together, and the top of the upper mold and the lower mold are both provided with a pull ring for lifting.

[0006] Preferably, both the upper and lower molds are frustum-shaped structures with a thicker top and a thinner bottom. The outer diameters of the top of the lower mold and the bottom of the upper mold are the same, and the slopes of the side walls of the two molds are the same.

[0007] Preferably, both the upper and lower molds are provided with annular reinforcing ribs at their tops. Multiple connecting strips are fixedly connected to the bottom wall of the reinforcing ribs. The connecting strips are evenly distributed in a ring, and pull rings are detachably fixed to the top of the connecting strips.

[0008] Preferably, the reinforcing rib has a slot, the connecting rod is inserted into the slot, and a locking nut is screwed onto the top of the connecting rod to fix the connecting rod and the upper mold.

[0009] Preferably, there are 3 links, with adjacent links spaced 120 degrees apart.

[0010] Preferably, the minimum inner diameter of both the upper and lower molds is less than 75cm, and the sum of their lengths is 2m.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The main improvement of this utility model's quick-assembly and disassembly iron ladle inner mold device is that the bolt connection between the upper and lower molds is changed to a long connecting rod connection. Workers do not need to enter the mold; they can operate from the top, reducing operational difficulty and safety risks. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 As shown, a quick-assembly and disassembly ladle inner mold device includes an upper mold 1 and a lower mold 2, which are fitted together. Both the upper mold 1 and the lower mold 2 are frustoconical structures with a thicker top and a thinner bottom. The outer diameter of the top of the lower mold 2 is the same as that of the bottom of the upper mold 1, and the sidewall slopes of the two molds are the same. The two molds are stacked together to form a mold for use. The two molds are placed inside the ladle shell 9, and then refractory material for the ladle lining is poured between the ladle shell 9 and the molds to form a filling layer 10.

[0019] like Figure 2 As described above, both the upper mold 1 and the lower mold 2 are provided with annular reinforcing ribs 11 at their tops. Multiple connecting strips 5 are fixedly connected to the bottom wall of the reinforcing ribs 11. The connecting strips 5 are evenly distributed in a ring, and a pull ring 6 is detachably fixed to the top of the connecting strips 5. An insert plate 7 can be inserted into the pull ring 6. The insert plate 7 is fixed to a lifting ring 8. The upper mold 1 or the lower mold 2 can be lifted out of the formed molten iron ladle by connecting the lifting ring 8 with a lifting device.

[0020] The connection structure between the upper mold 1 and the lower mold 2 is as follows: Figure 1The upper mold 1 and lower mold 2 each have multiple corresponding slots 3. A connecting rod 4 is inserted into each slot 3. The two ends of the connecting rod 4 are detachably fixed to the top of the upper mold 1 and the bottom of the lower mold 2, respectively. Preferably, there are three connecting rods 4, with adjacent connecting rods 4 spaced 120 degrees apart. The main improvement is changing the bolt connection of the half-mold to a long connecting rod connection. Workers do not need to enter the mold; they can operate from the top, reducing operational difficulty and safety risks. The minimum inner diameter of both the upper mold 1 and lower mold 2 is less than 75cm, and their combined length is 2m. Operating in such a narrow and elongated space is indeed inconvenient.

[0021] The reinforcing rib 11 has a slot, the connecting rod 4 is inserted into the slot, and the top of the connecting rod 4 is screwed with a locking nut to fix the connecting rod 4 and the upper mold 1. This connection method of locking the nut makes it easy to fix and easy to disassemble.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
