[0028] A fixing mechanism, which is arranged at the bottom of the support frame 1;

[0029] Among them, the fixing mechanism includes a first pneumatic cylinder 5, the top of the first pneumatic cylinder 5 is fixedly connected to the bottom of the support frame 1, and a rectangular block 6 is fixedly connected to the right side of the first pneumatic cylinder 5. The front and rear sides of the right side of the rectangular block 6 are hinged with connecting rods 7, and the other end of the connecting rod 7 is hinged with a clamping block 8. There are two clamping blocks 8. The outer surfaces of the two clamping blocks 8 are movably connected to the inner surface of the support frame 1, and the inner surfaces of the two clamping blocks 8 are movably connected to the outer surface of the limit block 3. The tops of the inner sides of the two clamping blocks 8 penetrate the mold 4 and extend to the inside of the mold 4. The two clamping blocks 8 move away from each other to release the fixing effect on the mold 4.

[0030] When the first pneumatic cylinder 5 is in operation, it will drive the rectangular block 6 to move to the right, thereby causing the two connecting rods 7 to rotate and drive the two clamping blocks 8 to move away from each other. When the two clamping blocks 8 move to the outside of the mold 4, the fixing effect on the mold 4 will be released. At this time, the mold 4 can be pulled outward to complete the replacement of the mold 4, thereby achieving the purpose of facilitating the replacement of molds 4 with different appearances.

[0031] Among them, the top of the workbench 2 is fixedly connected to a U-shaped bracket 9, the middle of the top of the U-shaped bracket 9 is fixedly connected to a second pneumatic cylinder 10, the bottom of the second pneumatic cylinder 10 passes through the U-shaped bracket 9 and extends to the bottom of the U-shaped bracket 9 and is fixedly connected to a cover plate 11.

[0032] When the second pneumatic cylinder 10 is in operation, it will drive the cover plate 11 to move downward to close the mold 4 .

[0033] A drainage hole 12 is provided in the middle of the cover plate 11 , and a funnel 13 located just above the drainage hole 12 is fixedly connected to the top of the cover plate 11 .

[0034] Such a design enables the liquid rubber to be introduced into the interior of the mold 4 through the funnel 13 and the drainage hole 12 .

[0035] A limiting groove 14 is provided inside the cover plate 11 and is located on the right side of the drainage hole 12 . A blade 15 is movably connected to the inner surface of the limiting groove 14 .

[0036] The blade 15 is designed to cut off the excess rubber.

[0037] The top of the cover plate 11 is fixedly connected with a driving motor 16 located on the right side of the limiting groove 14 , the other end of the output shaft of the driving motor 16 is fixedly sleeved with a rotating shaft 17 , and the outer surface of the rotating shaft 17 is fixedly sleeved with a rotating rod 18 .

[0038] When the driving motor 16 is running, the rotating shaft 17 will drive the rotating rod 18 to rotate.

[0039] Among them, the other end of the rotating rod 18 is hinged with a movable block 19, and the other end of the movable block 19 is hinged with a connecting block 20. The bottom of the connecting block 20 passes through the limiting groove 14 and is fixedly connected to the blade 15. The outer surface of the connecting block 20 is movably connected to the inner surface of the limiting groove 14. The connecting block 20 moves to the left, driving the blade 15 to move to the left to cut excess rubber.

[0040] The movable block 19 rotates to push the connecting block 20 to move leftward, and then the connecting block 20 drives the blade 15 to move leftward, thereby achieving the purpose of automatically cutting excess rubber.

[0041] There are four support frames 1 , the four support frames 1 have the same size, and the four support frames 1 are symmetrical with respect to the center of the workbench 2 .

[0042] The design of four support frames 1 provides a better supporting effect on the workbench 2 .

[0043] The working principle and use process of this utility model:

[0044] When casting pet rubber, first start the second pneumatic cylinder 10, which will drive the cover plate 11 to move downward until it fits with the mold 4, and then introduce the liquid rubber into the interior of the mold 4 through the funnel 13 and the drainage hole 12. After the pet rubber is formed, start the drive motor 16, which will cause the rotating shaft 17 to drive the rotating rod 18 to rotate, and then cause the movable block 19 to rotate and push the connecting block 20 to move to the left, so that the blade 15 moves to the left to cut the excess rubber, thereby achieving the purpose of automatically cutting the excess rubber.

[0045] When replacing a mold 4 with a different appearance, starting the first pneumatic cylinder 5 will drive the rectangular block 6 to move to the right, thereby causing the two connecting rods 7 to rotate and drive the two clamping blocks 8 to move away from each other. When the two clamping blocks 8 move to the outside of the mold 4, the fixing effect on the mold 4 will be released. At this time, pulling the mold 4 outward can achieve the purpose of replacing a mold 4 with a different appearance.
