[0016] Refer to Figures 1-4, the liquid medicine bag welding mold, including a base 1, symmetrically arranged guide rods 2 are fixedly connected to the base 1, symmetrically arranged frames 3 are fixedly connected to both of the two guide rods 2, rubber layers 4 are provided on the top and bottom walls of the multiple frames 3, symmetrically arranged guide frames 5 are fixedly connected to the interiors of the multiple frames 3, moving rods 6 are slidably connected to the multiple guide frames 5, symmetrically arranged pressure-bearing blocks 7 are fixedly connected to the opposite walls of the multiple moving rods 6, symmetrically arranged first molds 8 are slidably connected to both of the two guide rods 2 and the frames 3, second molds 9 are fixedly connected to the middle positions of both of the two guide rods 2 and the frames 3, lead screws 10 are rotatably connected to the interiors of the two guide rods 2, symmetrically arranged moving plates 11 are slidably connected to the interiors of the two guide rods 2, symmetrically arranged extrusion blocks 12 are fixedly connected to the multiple moving plates 11, and a scale 13 is provided on the base 1.

[0017] Furthermore, the lead screws 10 are all threadedly connected to the moving plates 11, the lead screws 10 are all arranged as bidirectional lead screws, and the lead screws 10 are convenient for driving the moving plates 11 to move.

[0018] Furthermore, the extrusion blocks 12 all pass through the side walls of the guide rods 2 and are located inside the frames 3.

[0019] Furthermore, the moving rods 6 are all in contact with the rubber layers 4, the sizes and shapes of the first molds 8 and the second molds 9 are the same, and when the moving rods 6 move, it is convenient to contact the rubber layers 4.

[0020] Furthermore, rotating blocks 14 are fixedly connected to the lead screws 10, and the rotating blocks 14 are convenient for rotating the lead screws 10.

[0021] When this device is in use, when it is necessary to change the distance between the first mold 8 and the second mold 9, the first mold 8 can be directly slid, and the first mold 8 is moved to the ideal position corresponding to the scale 13, and then the lead screw 10 is rotated by an external tool and the rotating block 14. The rotation of the lead screw 10 will drive the two moving plates 11 to move in opposite directions. The movement of the two moving plates 11 will drive the extrusion blocks 12 to slide inside the frames 3. Each extrusion block 12 will move towards the pressure-bearing block 7. When the extrusion block 12 moves to the obliquely arranged position of the pressure-bearing block 7, it will slowly squeeze the pressure-bearing block 7. At this time, the pressure-bearing blocks 7 will drive the moving rods 6 to move towards the rubber layer 4 when being squeezed. The movement of the moving rods 6 will squeeze and deform the rubber layer 4. At this time, the rubber layer 4 will tightly fit the inner wall of the first mold 8, and there is a great friction between the rubber layer 4 and the inner wall of the first mold 8. At this time, the position of the first mold 8 is fixed, and the welding work of the liquid medicine bag pipe orifice can be carried out.
