[0029] Reference Figure 1 and Figure 3The utility model provides an embodiment: an elbow S-shaped water swelling forming mold, including a base 1, a lower die base 12 is arranged on the upper part of the base 1, and the four outer corners of the lower die base 12 are fixedly connected with mounting blocks 15, the upper part of the base 1 is fixedly connected with a support frame 5, the inside of the support frame 5 is fixedly connected with a cylinder 6, the output end of the cylinder 6 is fixedly connected with a fixing plate 7, and the bottom of the fixing plate 7 is provided with an upper die base 8, the inside of the mounting block 15 and the fixing plate 7 are both threadedly connected with a screw 14, one end of the screw 14 is fixedly connected with a clamping block 22, the inside of the base 1 and the upper die base 8 are both provided with a clamping groove 23, the clamping block 22 is slidably connected to the inside of the clamping groove 23, and the left and right sides of the inside of the base 1 and the upper die base 8 are both provided with fixing components;

[0030] The fixing assembly includes a second spring 25, which is arranged on the left and right sides of the base 1 and the upper mold base 8. One end of the second spring 25 is fixedly connected to a stop block 26, which is arranged on the left and right sides of the screw 14. A through slot 24 is opened at the upper part of the slot 23, and one end of the second spring 25 is fixedly connected to the inside of the through slot 24, and the stop block 26 is slidably connected to the inside of the through slot 24.

[0031] The screw rod 14 is rotated to move the clamping block 22 away from the clamping slot 23 and simultaneously press the stopper 26 so that the stopper 26 slides inside the through slot 24 to press the second spring 25, so that the second spring 25 can be disassembled and replaced.

[0032] Reference Figure 1 and Figure 2 , the left and right sides of the bottom of the upper die seat 8 are fixedly connected with plug blocks 9, a first spring 18 is arranged inside the plug block 9, a slide slot 19 can be provided on the left side of the plug block 9, one end of the first spring 18 is fixedly connected inside the slide slot 19, the other end of the first spring 18 is fixedly connected with a moving block 20, the moving block 20 is slidably connected inside the slide slot 19, slots 21 are provided on the left and right sides of the upper part of the lower die seat 12, the plug block 9 and the moving block 20 are slidably connected inside the slot 21, and the pressing head 11 is slidably connected to the left and right sides of the interior of the lower die seat 12, and the pressing head 11 is slidably connected inside the slot 21;

[0034] The upper die base 8 is moved downward by starting the cylinder 6, so that the insertion rod 10 is inserted into the insertion hole 16, and the insertion block 9 is inserted into the slot 21. The slot 21 squeezes the first spring 18 through the moving block 20, so that the moving block 20 moves in the slide groove 19. When the moving block 20 loses its squeezing, the rebound force of the first spring 18 drives the moving block 20 to be inserted into the interior of the slot 21, so that the upper die base 8 and the lower die base 12 are molded together.

[0035] Reference Figure 1 The upper left, right, front and back sides of the base 1 are fixedly connected with support blocks 2, the upper part of the support block 2 is fixedly connected with a punch needle seat 4, the output end of the punch needle seat 4 is fixedly connected with a punch needle tube 17, the lower die seat 12 and the upper die seat 8 are both provided with a tube cavity 13, the punch needle tube 17 is arranged inside the tube cavity 13, and one side of the punch needle seat 4 is fixedly connected with a high-pressure water inlet joint 3.

[0037] Working principle: When the device is needed, the cylinder 6 is started to drive the upper die seat 8 to move through the fixed plate 7, so that the upper die seat 8 drives the insertion rod 10 to be inserted into the inside of the insertion hole 16, and the insertion block 9 is inserted into the inside of the slot 21 at the same time. The slot 21 squeezes the moving block 20, so that the moving block 20 squeezes the first spring 18, so that it slides inside the slide groove 19. When the slot 21 no longer squeezes the moving block 20, the first spring 18 is inserted into the slot 21 due to its rebound force, so that the upper die seat 8 and the lower die seat 12 are molded together, and high-pressure water is introduced through the high-pressure water inlet joint 3. , so that it drives the punch needle tube 17 through the punch needle seat 4 to perform water swelling pre-forming on the pipe fitting, thereby realizing fixed mold closing of the mold seat, avoiding the influence of molding effect due to the mold not being fixed during water swelling molding. When it is necessary to replace molds of other specifications, the screw 14 is rotated to drive the block 22 to move so that it is separated from the slot 23. At the same time, the second spring 25 is squeezed through the block 26 to slide in the through slot 24. The block 22 is no longer fixed and can be disassembled, thereby realizing quick and convenient disassembly and replacement of the mold, and improving the practicality of the device.
