The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] Please see Figure 1-5 This utility model provides a technical solution: a seamless welded metal hand mold, including a hand mold 1, a metal upper mold 2, and a metal lower mold 7. The metal upper mold 2 and the metal lower mold 7 are arranged in an upper and lower correspondence. The upper surface of the metal lower mold 7 is provided with three positioning holes 16.

[0032] The three positioning holes 16 are provided with placement holes on their left and right inner walls, and three positioning rods 15 are fixedly connected to the lower surface of the upper mold 2 of the metal arm. Circular grooves 17 are provided on both the left and right sides of the positioning rods.

[0033] Furthermore, the inner walls of the two circular grooves 17 are slidably connected with locking posts 14, and the opposite surfaces of the two locking posts 14 are fixedly connected with springs 18.

[0034] Two springs 18 are fixedly connected to the inner walls of corresponding circular grooves 17, and the structures on the three positioning rods 15 are exactly the same.

[0035] Furthermore, a second arc-shaped groove 6 is provided on the rear surface of the upper mold 2 of the metal arm, and a first mounting hole 3 is provided on the rear surface of the upper mold 2 of the metal arm, the first mounting hole 3 being located below the second arc-shaped groove 6.

[0036] Furthermore, a first arc-shaped groove 5 is provided on the rear surface of the lower die 7 of the metal arm, and a second mounting hole 4 is provided on the rear surface of the lower die 7 of the metal arm, the second mounting hole 4 being located above the first arc-shaped groove 5.

[0037] Furthermore, a first arc-shaped card plate 10 that is adapted to the second arc-shaped card slot 6 is fixedly connected to the front surface of the hand mold 1;

[0038] The front surface of the hand mold 1 is fixedly connected to a first mounting rod 9 that is adapted to the first mounting hole 3, and the outer surface of the first mounting rod 9 is fixedly wrapped with a first rubber sleeve 8.

[0039] Furthermore, a second mounting rod 11 adapted to the second mounting hole 4 is fixedly connected to the front surface of the hand mold 1, and a second rubber sleeve 12 is fixedly wrapped around the outer surface of the second mounting rod 11.

[0040] The front surface of the hand mold 1 is fixedly connected to a second arc-shaped card plate 13 that is adapted to the first arc-shaped card slot.

[0041] Furthermore, when seamlessly welding the entire hand mold 1, first place the lower metal arm mold 7 flat on the ground, then place the upper metal arm mold 2 on the upper surface of the lower metal arm mold 7, so that the three positioning rods 15 enter the interior of the three positioning holes 16. When the multiple locking pins 14 contact the inner wall of the positioning hole 16, they will enter the inner wall of the corresponding circular groove 17 under pressure and compress the corresponding spring 18.

[0042] When multiple locking pins 14 come into contact with the placement holes inside the positioning holes 16, they will automatically slide through the inner wall of the circular groove 17 under the action of the spring 18 and extend into the interior of the corresponding placement hole, thereby completing the assembly of the lower metal arm mold 7 and the upper metal arm mold 2.

[0043] Furthermore, the hand mold 1 is then picked up, and the first arc-shaped card plate 10 and the second arc-shaped card plate 13 are respectively inserted into the interior of the second arc-shaped card groove 6 and the first arc-shaped card groove 5. Then the first mounting rod 9 and the second mounting rod 11 will enter the interior of the first mounting hole 3 and the second mounting hole 4 respectively.

[0044] When the second rubber sleeve 12 and the first rubber sleeve enter the first mounting hole 3 and the second mounting hole 4 respectively, the workers need to use force to squeeze the second rubber sleeve 12 and the first rubber sleeve into the interior of the first mounting hole 3 and the second mounting hole 4 respectively, thereby completing the installation of the entire metal hand mold.

[0045] Among them, the assembly of the hand mold 1 with the upper metal arm mold 2 and the lower metal arm mold 7 is completed by using a snap-fit ​​method. The entire assembly process does not require the use of external wall tools, which improves the convenience of assembling the metal hand mold before seamless welding.

[0046] The assembly of the hand mold 1 with the upper metal arm mold 2 and the lower metal arm mold 7 is completed by using a snap-fit ​​method. During seamless welding, the workers do not need to worry about misalignment, which improves the quality of seamless welding. In addition, the metal hand mold has the advantages of long service life and can be recycled and reused.

[0047] Working principle: When seamlessly welding the entire hand mold 1, first place the lower metal arm mold 7 flat on the ground, then place the upper metal arm mold 2 on the upper surface of the lower metal arm mold 7, so that the three positioning rods 15 enter the interior of the three positioning holes 16. When the multiple locking pins 14 contact the inner wall of the positioning hole 16, they will enter the inner wall of the corresponding circular groove 17 under pressure and compress the corresponding spring 18.

[0048] When multiple locking pins 14 come into contact with the placement holes inside the positioning holes 16, they will automatically slide through the inner wall of the circular groove 17 under the action of the spring 18 and extend into the interior of the corresponding placement hole, thereby completing the assembly of the lower metal arm mold 7 and the upper metal arm mold 2.

[0049] Furthermore, the hand mold 1 is then picked up, and the first arc-shaped card plate 10 and the second arc-shaped card plate 13 are respectively inserted into the interior of the second arc-shaped card groove 6 and the first arc-shaped card groove 5. Then the first mounting rod 9 and the second mounting rod 11 will enter the interior of the first mounting hole 3 and the second mounting hole 4 respectively.

[0050] When the second rubber sleeve 12 and the first rubber sleeve enter the first mounting hole 3 and the second mounting hole 4 respectively, the workers need to use force to squeeze the second rubber sleeve 12 and the first rubber sleeve into the interior of the first mounting hole 3 and the second mounting hole 4 respectively, thereby completing the installation of the entire metal hand mold.

[0051] Among them, the assembly of the hand mold 1 with the upper metal arm mold 2 and the lower metal arm mold 7 is completed by using a snap-fit ​​method, and the entire assembly process does not require the use of external wall tools.

[0052] The assembly of the hand mold 1 with the upper metal arm mold 2 and the lower metal arm mold 7 is completed by using a snap-fit ​​method.
