The setting of the fixed plate 13 can make the rotating rod 14 more stable, and the outer wall of the rotating rod 14 is fixedly connected with a rotating block 12, and the outer wall of the rotating block 12 is hinged with a connecting rod 10, and the connecting rod 10 is driven by the rotating block 12 to make corresponding movements, and the connecting rod 10 is provided with two groups, and the outer wall of the connecting rod 10 is hinged with a movable block 11, and the movable block 11 is provided with two groups, and the outer walls of the two groups of movable blocks 11 are arc-shaped, and the arc-shaped setting is more suitable for the inner wall of the rain boots.

[0028] Furthermore, the front end of the fixed table 7 is fixedly connected to a limiting assembly, the bottom end of the limiting assembly is plugged into the inner wall of the rotating rod 14, and the rotating rod 14 is plugged and limited by the limiting assembly. The limiting assembly includes a limiting block 9, the outer wall of the limiting block 9 is fixedly connected to the front end of the fixed table 7, the bottom end of the limiting block 9 is elastically connected to a plug-in column 16 through a connecting spring 15, and the outer wall of the plug-in column 16 is provided with a circular plate 1, and the bottom end of the connecting spring 15 is fixedly connected to the top of the circular plate 1. The setting of the circular plate 1 ensures that the plug-in column 16 will not separate from the inner wall of the limiting block 9 when moving, the outer wall of the rotating rod 14 penetrates and is rotatably connected to the inner wall of the fixed table 7, the outer wall of the movable block 11 is slidably connected to the inner wall of the fixed table 7, and the two groups of movable blocks 11 are vertically moved by the rotation of the rotating rod 14.

[0029] Furthermore, one end of the connecting spring 15 is fixedly connected to the outer wall of the plug-in column 16, and the other end of the connecting spring 15 is fixedly connected to the inner wall of the limit block 9. The outer wall of the plug-in column 16 passes through and is slidably connected to the inner wall of the limit block 9. When the plug-in column 16 moves, it will squeeze the connecting spring 15, so that the length of the connecting spring 15 becomes shorter.

A plurality of groups of plug-in holes are provided at the front end of the rotating rod 14, and the bottom end of the plug-in column 16 is plugged into the inner wall of the plug-in hole. The setting of the plurality of groups of plug-in holes means that the rotating rod 14 rotates at different angles and can be fixed by the plug-in column 16. The different rotation angles of the rotating rod 14 can make the two groups of movable blocks 11 move different distances, thereby adapting to different models of mold shells 4.

The outer wall of the plug board 20 penetrates and is slidably connected to the inner wall of the positioning block 18. When the plug board 20 moves, the length of the limit spring 19 will be squeezed, so that the length of the limit spring 19 becomes shorter. When the plug board 20 does not move, the plug board 20 is reset due to the elasticity of the limit spring 19.

[0031] Furthermore, the bottom end of the positioning block 18 is plugged into the inner wall of the connecting seat 5, and the bottom end of the plug plate 20 is plugged into the inner side wall of the connecting seat 5. The plugging of the plug plate 20 prevents the positioning block 18 from being separated from the inner wall of the connecting seat 5. Two groups of plug plates 20 are provided, which are respectively located at the front and rear ends of the positioning block 18. The two groups of plug plates 20 are staggered, and the staggered setting can save more space. The top inner wall of the rear end plug plate 20 is rotatably connected to the connecting block 17, and the outer wall of the connecting block 17 is plugged into the top of the front end plug plate 20.

[0032] Working principle: When relevant personnel need to use a larger rain boot mold shell 4, first move the plug-in column 16 inside the limit block 9 upward to release the limit of the plug-in column 16 on the rotating rod 14, and then the rotating rod 14 can be rotated, so that the rotating rod 14 drives the rotating block 12 to rotate. At this time, the two groups of connecting rods 10 will rotate accordingly, and then drive the two groups of movable blocks 11 to move to both ends, so as to expand the size of the fixed platform 7. When the size of the two groups of movable blocks 11 is consistent with the size of the rain boot mold shell 4, loosen the plug-in column 16, so that the plug-in column 16 and the rotating rod 14 are plugged and fixed, and then can adapt to the larger rain boot mold shell 4, thereby avoiding the shaking of the finished product of the larger rain boot mold shell 4 after injection molding.

[0033] When the relevant personnel need to replace the rain boot mold shell 4, first rotate the connecting block 17 upwards, such as Figure 7As shown, the two groups of plug plates 20 can then be moved toward the middle to release the connection between the two groups of plug plates 20 and the connecting seat 5, and then the mold shell 4 can be moved upward, thereby facilitating the disassembly and replacement of the mold shell 4 and avoiding the traditional bolt-fixed installation.
