[0027] Example 1

[0028] like Figure 1 and 3 As shown, the utility model provides a technical solution:

[0029] A quick-disassembly and assembly-type inner mold structure, which at least includes but is not limited to a main support template 1 and an auxiliary support template 2. The main support template 1 and the auxiliary support template 2 are arranged in pairs, so that the main support template 1 and the auxiliary support template 2 are staggered to form a cylindrical structure; the contact parts of the main support template 1 and the auxiliary support template 2 are both oblique structures; a wedge-shaped cavity is formed between adjacent main support templates 1, and the auxiliary support template 2 can be inserted into the wedge-shaped cavity.

[0030] Based on the above structure, when in use, the main supporting formwork 1 is first placed symmetrically in the area to be supported, and then the auxiliary supporting formwork 2 is inserted into the wedge-shaped cavity between adjacent main supporting formworks 1 to form a complete formwork structure. When disassembling, only one side of the auxiliary supporting formwork 2 needs to be slid out to achieve rapid removal of the entire internal formwork.

[0031] As an example, an internal support frame 3 is also provided in the cylindrical structure formed by the main support formwork 1 and the auxiliary support formwork 2 , and a plurality of support rods 32 are provided on the internal support frame 3 , and each of the main support formwork 1 and the auxiliary support formwork 2 is in contact with at least two support rods 32 .

[0032] Based on the above structure, the cylindrical inner mold structure formed by the main supporting template 1 and the auxiliary supporting template 2 is supported by the internal support frame 3 to ensure the stability of the inner mold.

[0033] As an example, the internal support frame 3 may include a central connecting rod 31, a main support rod 32, a secondary support rod 34 and a hanging ring 33. The central connecting rod 31 is a rectangular steel structure. The main support rod and the secondary support rod are arranged in two layers along the length direction of the central connecting rod 31. The central connecting rod is provided with a slide slot hole 35 for the main support rod to pass through; the main support rod is arranged in the slide slot hole, and the main support rod can move along the length direction of the slide slot hole; the secondary support rod is arranged on the side wall of the central connecting rod that is perpendicular to the slide slot hole; the hanging ring is arranged at the top position of the central connecting rod.

[0034] The auxiliary support rod is fixedly connected to the inner wall of the auxiliary support formwork, and the main support rod is fixedly connected to the side wall of the main support formwork.

[0035] Based on the above structure, due to the existence of the slide slot hole, when the component is cast and formed, the central connecting rod is lifted by the lifting ring to move upward, and the secondary support rod and the auxiliary support template directly connected thereto are driven to move upward. The area of ​​the auxiliary support template is small, so the auxiliary support template can be slid with a small force. At the same time, after the auxiliary support template slides, the entire inner mold structure will be unloaded, and then gradually pulled upward. When the main support rod moves to the lowest end of the slide slot hole, the central connecting rod drives the unloaded main support template upward to complete the disassembly operation;

[0036] As an example, a limit block 36 is provided on the main support rod, and the limit block is provided in the slide slot hole, and there is a gap between the limit block and the side wall of the slide slot hole.

[0037] Based on the above structure, the main support rod is restricted from moving left and right in the slide slot hole of the central connecting rod by a limit block, so that it can only move up and down along the length direction of the slide slot hole. This can simplify the disassembly and assembly process of the main template and improve the assembly accuracy.

[0038] As an example, the main support template 1 and the auxiliary support template 2 are both arc-shaped structures, the overall structure of the auxiliary support template 2 is a structure that is large at the top and small at the bottom, and the overall structure of the main support template 1 is a structure that is small at the top and large at the bottom. Only in this way can the auxiliary support template 2 be quickly plugged in.

[0039] As an example, the auxiliary support formwork 2 may include an upper auxiliary portion 21, a lower auxiliary portion 22 and a lateral auxiliary portion 23; the axis of the upper auxiliary portion 21 is collinear with the central axis of the lower auxiliary portion 22, the lateral auxiliary portions 23 are respectively arranged between the upper auxiliary portion 21 and the lower auxiliary portion 22, and the projection of the auxiliary support plate on the vertical plane is an isosceles trapezoidal structure.

[0040] The central angle of the upper auxiliary part 21 is 45°, and the central angle of the lower auxiliary part is 22.5°; the size of the upper auxiliary part 21 is one eighth of the top size of the inner mold structure; the size of the lower auxiliary part 22 is one sixteenth of the bottom size of the inner mold structure.

[0041] Based on the above structure, the size of the upper auxiliary part 21 is set to one eighth of the top size of the inner mold structure; the size of the lower auxiliary part 22 is set to one sixteenth of the bottom size of the inner mold structure. In this way, the size of the auxiliary support plate can be reduced as much as possible, thereby reducing the difficulty of disassembling the auxiliary support plate and reducing the difficulty of disassembly.

[0042] As an example, the main supporting formwork 1 may include an upper supporting portion 11, a lower supporting portion 12 and a lateral supporting portion 13; the axis of the upper supporting portion 11 is collinear with the central axis of the lower supporting portion 12, and the lateral supporting portions 13 are respectively arranged between the upper supporting portion 11 and the lower supporting portion 12, and the projection of the main supporting formwork on the vertical plane is an isosceles trapezoidal structure.

[0043] The central angle of the upper support part 11 is 135°, and the central angle of the lower support part is 157.5°; the size of the upper support part 11 is three-eighths of the top size of the inner mold structure; the size of the lower support part 12 is seven-sixteenths of the bottom size of the inner mold structure.

[0044] Based on the above structure, the size of the upper support part 11 is set to three-eighths of the top size of the inner mold structure; the size of the lower support part 12 is set to seven-sixteenths of the bottom size of the inner mold structure. In this way, the size of the main support template can be increased as much as possible, thereby increasing the stability of the support, while cooperating with the auxiliary support plate for quick disassembly and assembly.

[0045] As an example, the lateral auxiliary portion 23 may include an inner auxiliary edge 231 and an outer auxiliary edge 232; a positive inclined surface structure is formed between the inner auxiliary edge 231 and the outer auxiliary edge 232; the lateral support portion 13 may include an inner support edge 131 and an outer support edge 132, and a reverse inclined surface structure is formed between the inner support edge 131 and the outer support edge 132; the slope and gradient of the positive inclined surface structure are matched with those of the reverse inclined surface structure, so that the positive inclined surface structure and the reverse inclined surface structure can fit tightly.

[0046] Based on the above structure, since a positive slope structure and a reverse slope structure are arranged on the side walls of the main support template and the auxiliary support plate, a guide groove structure is formed. On the one hand, the disassembly and assembly speed can be accelerated. On the other hand, the reverse slope structure can also limit the positive slope structure to prevent the auxiliary support plate from detaching from the main support template.

[0047] Through this solution, the internal mold can be formed quickly. At the same time, when demolding, it is only necessary to move the internal support frame 3. The auxiliary support mold can form a gap with the component under the action of a smaller force, so that the mold and the component can be separated quickly, minimizing the damage of the mold to the surface of the component.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
