[0002] With the rapid improvement of the current industrial level, the conventional rectangular furnace bottom prefabricated parts have also been improved. The conventional rectangular furnace prefabricated parts can only be used for rectangular furnaces single - handedly. With the research and development and use of hexagonal furnace bottom prefabricated parts, the hexagonal furnace bottom prefabricated parts have gradually replaced the rectangular furnace bottom prefabricated parts. The hexagonal furnace bottom prefabricated parts can be placed in a net shape, and the interface is in a V - shape with the horizontal plane, reducing the contact area between the furnace rake and the prefabricated part interface, reducing the damage to the prefabricated part when the furnace rake is used, preventing stress concentration from causing damage to the furnace bottom, and can meet various furnace types such as rectangular furnaces and circular furnaces, with strong applicability.

[0003] When forming the hexagonal furnace bottom prefabricated part, a forming die seat is required. Most of the existing forming die seats are only adapted to rectangular furnace bottom prefabricated parts, which is inconvenient for the forming of hexagonal furnace bottom prefabricated parts, not convenient for quick assembly and operation, and has certain limitations in use. Summary of the Utility Model

Assembly clamping plates are fixed at the top and bottom of the two connecting plates on the same side. Connecting grooves are opened on the outer surface of the lower die seat, the upper and lower sides of the outer surface of the middle die seat and the outer surface of the upper die seat. Adjacent two connecting grooves form an assembly clamping groove. The two assembly clamping plates at the same horizontal height are clamped in the assembly clamping groove at the corresponding position.

[0012] With the above solution, by using the elasticity of the spring in cooperation with the locking plate, when the locking plate is pressed into the groove, the spring deforms.

[0022] Please refer to Figures 1-4 , the present invention provides a forming structure for the bottom precast part of the furnace, including a forming die base 1. The forming die base 1 includes a lower die base 2, a middle die base 3, an upper die base 4 and a connecting part 6. The lower die base 2, the middle die base 3 and the upper die base 4 are arranged in sequence from bottom to top. A forming cavity is formed inside the lower die base 2, the middle die base 3 and the upper die base 4, and a formed furnace bottom shell 5 is formed in the forming cavity. The number of the middle die bases 3 is several, and several middle die bases 3 are arranged with their heads and tails fitting together. A pouring port pipe communicating with the forming cavity is installed through one of the middle die bases 3. The connecting part 6 includes four connecting plates 7. Assembly clamping plates 8 are fixed at the top and bottom of two connecting plates 7 on the same side. Connecting grooves are opened on the outer surface of the lower die base 2, the upper and lower sides of the outer surface of the middle die base 3 and the outer surface of the upper die base 4. Adjacent two connecting grooves form an assembly clamping groove. Two assembly clamping plates 8 at the same horizontal height position are clamped in the assembly clamping grooves at the corresponding positions. An insertion plate 9 is fixedly installed at the end of one side of the assembly clamping plate 8, and a plate sleeve 10 is fixedly installed at the end of the other side of the assembly clamping plate 8. The insertion plate 9 is inserted inside the plate sleeve 10, and a groove is opened on the side surface of the insertion plate 9, and a locking plate 14 is movably arranged inside the groove. A locking hole for the locking plate 14 to insert is opened on the plate sleeve 10.

[0023] By setting the lower die base 2 and the middle die base 3 to cooperate with the upper die base 4 and the connecting piece 6, after the lower die base 2, the middle die base 3 and the upper die base 4 are assembled in sequence from bottom to top, the assembly card plate 8 is used in cooperation with the insertion plate 9 and the plate sleeve 10 to realize the locking operation between the lower die base 2 and the middle die base 3 and between the middle die base 3 and the upper die base 4. Furthermore, it is convenient for the assembly operation of the forming die base 1, convenient for the forming use of the hexagonal furnace bottom prefabricated part, with a simple structure and convenient operation.

[0024] The inner wall of the connecting groove is fixedly installed with a positioning card plate 15, and the assembly card plate 8 is provided with positioning card holes for the positioning card plate 15 to be inserted into. By using the positioning card plate 15 in cooperation with the positioning card holes, it can play a positioning and guiding effect during the assembly of the assembly card plate 8, and also play a limiting effect in the vertical direction, avoiding the separation phenomenon between the lower die base 2 and the middle die base 3 and between the middle die base 3 and the upper die base 4.

[0025] Sealing grooves are opened on the upper surface of the lower die base 2, the lower surface and the upper surface of the middle die base 3, and the lower surface of the upper die base 4, and sealing rings 11 are embedded in the sealing grooves. By using the sealing rings 11 in cooperation with the sealing grooves, it can ensure the good sealing characteristics between the lower die base 2 and the middle die base 3 and between the middle die base 3 and the upper die base 4.

[0026] A plurality of springs 13 are fixedly installed on the inner wall of the groove on the insertion plate 9, and the plurality of springs 13 are fixedly connected to the side surface of the locking plate 14. By using the elasticity of the springs 13 in cooperation with the locking plate 14, when the locking plate 14 is pressed into the groove, the springs 13 are deformed. When the insertion plate 9 is inserted into the plate sleeve 10, the elasticity of the springs 13 can be used to drive the locking plate 14 to reset and insert into the locking hole, thereby realizing the convenient locking of the insertion plate 9 and the plate sleeve 10.

[0027] An expansion rod 12 is arranged inside the spring 13, and both ends of the expansion rod 12 are fixedly connected to the inner wall of the groove and the side surface of the locking plate 14 respectively. The expansion rod 12 expands and contracts synchronously with the deformation of the spring 13, playing a supporting effect on the locking plate 14 to prevent the locking plate 14 from shaking.

[0028] During use, when assembly is required, first align the middle die base 3 with the lower die base 2, then align the upper die base 4 with the middle die base 3, then align the assembly card plate 8 with the assembly card slot and use the positioning card plate 15 and the positioning card holes for positioning and guiding. During positioning and guiding, press the locking plate 14 so that the locking plate 14 squeezes the springs 13 to deform and enters the groove. When the insertion plate 9 is inserted into the plate sleeve 10, the elasticity of the springs 13 is used to drive the locking plate 14 to reset and insert into the locking hole, realizing the installation and locking of the assembly card plate 8, and then completing the assembly operation of the forming die base 1. Then, the hexagonal furnace bottom prefabricated part material is injected through the injection port pipe for forming operation.
