[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, Figure 1 What is shown is a schematic front view of the demoulding device in the embodiment; Figure 2 What is shown is a schematic top view of the demoulding device in the embodiment, Figure 3 It shows Figure 1 A cross-sectional schematic diagram in FIG.

[0025] The device includes:

[0026] Ladle 10;

[0027] A mold assembly 20, which extends from the opening end of the ladle 10 into the interior of the ladle 10 and forms a gap 40 with all the inner side walls of the ladle 10, and the furnace lining material 1 is injected into the gap 40;

[0028] The demolding member 30 outputs gas with a certain pressure at its output end. The demolding member 30 is inserted from the top of the mold assembly 20. The gas output from the output end of the demolding member 30 enters the gap between the bottom of the mold assembly 20 and the contact surface of the furnace lining material 1. The output gas applies upward pressure to the mold assembly 20, lifting the mold assembly 20 to achieve demolding.

[0029] The mold assembly 20 and the gap 40 formed between the mold assembly 20 and the inner side wall of the ladle 10 can realize the filling and molding of the furnace lining material 1; after the furnace lining material 1 is filled, the filling and compaction of the furnace lining material 1 can be realized by inserting a vibrating rod;

[0030] Specifically, the furnace lining material 1 is a refractory castable, which is a refractory material used for casting to form a furnace lining, and is usually made by mixing refractory powder and a binder and can form a dense furnace lining structure;

[0031] The demoulding member 30 demoulds the mold assembly 20 after the furnace lining material 1 is formed and solidified, and the mold assembly 20 is lifted up by air pressure to reduce the damage of the furnace lining material 1 during the demoulding process, and can also make the demoulding operation fast and simple, saving manpower.

[0032] like Figure 1 , Figure 2 , Figure 3 As shown, Figure 1 What is shown is a schematic front view of the demoulding device in the embodiment; Figure 2 What is shown is a schematic top view of the demoulding device in the embodiment, Figure 3 It shows Figure 1 A cross-sectional schematic diagram in FIG.

[0033] The mold assembly 20 includes a mold 21 and a support frame 22. The mold 21 has a cavity inside and an opening at the top. The support frame 22 is fixedly arranged at the open end of the mold 21. The length of the support frame 22 is greater than the diameter length of the open end of the ladle 10. After the mold 21 is extended into the ladle 10, the support frame 22 is movably overlapped at the open end of the ladle 10 to make the mold 21 in a raised shape, thereby ensuring the smooth formation of the gap 40.

[0034] The shape of the mold 21 matches the ladle 10, and the diagonal length of the cross section of the mold 21 is smaller than the diagonal length of the cross section of the ladle 10. The support frame 22 is provided to support the mold 21 after the mold 21 is placed in the ladle 10, so that the mold 21 is erected, thereby ensuring that the bottom end of the mold 21 can also smoothly form a gap 40 with the ladle 10.

[0035] The demoulding member 30 is a tube body, and the demoulding member 30 is inserted from the opening end of the mold 21, and the end thereof passes through the bottom end side wall of the mold 21;

[0036] The tube-shaped demoulding member 30 plays the role of conveying gas, and specifically, also includes an air pump, the output end of the air pump is connected to the input end of the tube body, and gas with a certain air pressure is input and transported through the tube body to the output end of the tube body for discharge;

[0037] The gas output from the output end of the tube body enters the gap between the bottom end of the mold 21 and the contact surface of the furnace lining material 1 , and the output gas applies upward pressure to the mold assembly 20 , thereby achieving lifting and demolding of the mold assembly 20 .

[0038] Specifically, the support frame 22 is a cross-arranged rod body, and the side wall of the open end of the ladle 10 is provided with a positioning plate 12 at the position corresponding to the rod body, and the positioning plate 12 is provided with a positioning groove at one end close to the support frame 22, and each rod body of the support frame 22 is overlapped in the positioning groove at the corresponding position;

[0039] By setting up the crossed rods, the mold 21 is relatively stable when it is erected, and by setting up the positioning plate 12 and the supporting frame 22 to overlap with each other, a certain positioning effect is played, so that the mold 21 is accurately installed;

[0040] The positioning plate 12 is also provided with a positioning hole 221, and a positioning column is correspondingly provided on one end of the rod body of the support frame 22 close to the positioning hole 221, and the positioning column is movably inserted into the positioning hole 221;

[0041] By providing the movable plug-in positioning holes 221 and the positioning columns, the mold 21 can be smoothly released from the mold without affecting the mold 21. The installation of the mold 21 and the support frame 22 is further positioned, and the gap 40 can be made as uniform as possible, thereby ensuring that the side wall thickness of the furnace lining material 1 is relatively uniform.

[0042] The ladle 10 includes a pouring gate 11 for pouring, and an extension portion 211 matching its shape is provided at a position corresponding to the pouring gate 11 on the mold 21. A cover 23 is also provided inside the open end of the mold 21; the cover 23 is provided to prevent the furnace lining material 1 from entering the mold 21.

[0043] Working principle: When the device is in use, firstly, the mold 21 is movably overlapped into the open end of the ladle 10 through the corresponding equipment to make the mold 21 stand up, and then the furnace lining material 1 is filled into the gap 40 formed between the mold assembly 20 and the inner side wall of the ladle 10. After the furnace lining material 1 is filled and formed and solidified, the air pump is turned on. The air pump inputs gas with a certain air pressure into the tube body and transports it to the output end of the tube body through the tube body for discharge. The discharged gas enters the gap between the contact surface of the bottom end of the mold assembly 20 and the furnace lining material 1. The output gas applies upward pressure to the mold assembly 20, and lifts the mold assembly 20 to achieve demolding.

[0044] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
