A piston block 8 is movably arranged inside the mounting frame 9, a connecting plate 7 is fixedly arranged on the left side of the piston block 8, a first spring 20 is fixedly arranged inside the mounting frame 9, and the left end of the first spring 20 is fixedly connected to the piston block 8, a through hole 11 is opened on the right side of the mounting frame 9, and the number of through holes 11 is multiple, and the multiple through holes 11 are distributed in a rectangular array, and the gas inside the cavity 10 is discharged through the through holes 11, a movable mold 12 is fixedly arranged on the right side of the mounting frame 9, and a guide assembly is arranged inside the bottom plate 1, and the guide assembly includes a guide block 21 fixedly arranged at the bottom of the mounting frame 9, a support shaft 23 is fixedly arranged on the surface of the guide block 21, and a moving wheel 22 is rotatably arranged on the surface of the support shaft 23, and the moving wheel 22 is slidably connected to the bottom plate 1, and the mounting frame 9 drives the guide block 21 to move when the guide block 21 moves. The guide block 21 drives the moving wheel 22 to slide inside the bottom plate 1 through the support shaft 23 to prevent the movable mold 12 from deflecting during the movement and improve the stability of the device. The top of the bottom plate 1 is fixedly provided with a right support plate 3, and the left side of the right support plate 3 is fixedly provided with a fixed mold 14. The right side of the fixed mold 14 is provided with a cooling component, and the cooling component includes a mounting plate 18 and a cooling plate 19.

The cooling plate 19 is started to cool the internal product through the mounting plate 18 and the fixed mold 14 to accelerate the product production speed. The surface of the fixed mold 14 is provided with a buffer component, and the buffer component includes a positioning block 13 and a positioning frame 15. The positioning frame 15 and the fixed mold 1 4 is fixedly installed on the front and rear sides, the positioning block 13 and the front and rear sides of the movable mold 12 are fixedly installed, a positioning rod 16 is fixedly arranged inside the positioning frame 15, and a second spring 17 is overlapped on the surface of the positioning rod 16. The right end of the second spring 17 is fixedly installed on the positioning frame 15, and a support pad 24 is fixedly arranged at the bottom of the bottom plate 1. The number of the support pads 24 is multiple. The plastic mold with high stability drives the connecting plate 7, the piston block 8, the mounting frame 9 and the movable mold 12 to move through the telescopic component. When the movable mold 12 moves to the right and contacts the fixed mold 14, the movable mold 12 drives the positioning block 13 to move to the right and enter the interior of the positioning frame 15, and slides along the positioning rod 16 to compress the second spring 17, and the pressure on the fixed mold 14 is reduced by the rebound effect of the second spring 17.When the movable mold 12 moves to the left and away from the fixed mold 14, the movable mold 12 drives the mounting frame 9, the piston block 8 and the connecting plate 7 to move to the left together. The connecting plate 7 moves to the left and contacts the push plate 6. The push plate 6 pushes the piston block 8 to slide to the right inside the cavity 10 through the connecting plate 7. The piston block 8 slides to the right and slowly discharges the air inside the cavity 10 through the through hole 11. When the air inside the cavity 10 is discharged, because the through hole 11 is small, the gas cannot be discharged quickly, forming a force, thereby reducing the pressure on the mounting frame 9, and then reducing the pressure on the movable mold 12. The device solves the problem that the movable mold 12 collides and produces a slight displacement when it contacts the fixed mold 14 or returns to its original position, thereby improving the stability of the device and thus improving the production quality of the plastic mold.
[0022] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.
[0023] When in use: drive the telescopic cylinder 4 to extend the output end, push the connecting rod 5 to move rightward, the connecting rod 5 drives the mounting frame 9 and the movable mold 12 to move rightward, the mounting frame 9 drives the connecting plate 7 to move rightward through the piston block 8, the mounting frame 9 moves rightward to drive the guide block 21 to move, the guide block 21 moves through the support shaft 23 to drive the moving wheel 22 to roll inside the bottom plate 1, when the movable mold 12 moves rightward and contacts the fixed mold 14, the movable mold 12 drives the positioning block 13 to move rightward into the interior of the positioning frame 15, and slides along the positioning rod 16 to compress the second spring 17, and the pressure on the fixed mold 14 is reduced by the rebound effect of the second spring 17, when the product needs to be taken out When the piston block 8 is pushed to the right, the air in the cavity 10 is slowly discharged through the through hole 11. When the air in the cavity 10 is discharged, the gas cannot be discharged quickly because the through hole 11 is small, thus forming a leftward force to push the piston block 8. At the same time, when the piston block 8 slides to the right, it compresses the first spring 20, and the piston block 8 can be pushed back to its original position through the rebound effect of the first spring 20.
[0024] In summary, the plastic mold with high stability drives the connecting plate 7, the piston block 8, the mounting frame 9 and the movable mold 12 to move through the telescopic assembly. When the movable mold 12 moves to the right and contacts the fixed mold 14, the movable mold 12 drives the positioning block 13 to move to the right and enter the interior of the positioning frame 15, and slides along the positioning rod 16 to compress the second spring 17. The rebound effect of the second spring 17 reduces the pressure on the fixed mold 14. When the movable mold 12 moves to the left away from the fixed mold 14, the movable mold 12 drives the mounting frame 9, the piston block 8 and the connecting plate 7 to move to the left together. The connecting plate 7 moves to the left and contacts the push plate 6, and the push plate 6 is pushed. The plate 6 pushes the piston block 8 to slide rightward inside the cavity 10 through the connecting plate 7. The piston block 8 slides rightward to slowly discharge the air inside the cavity 10 through the through hole 11. When the air inside the cavity 10 is discharged, because the through hole 11 is small, the gas cannot be discharged quickly, forming a force, thereby reducing the pressure on the mounting frame 9, and then reducing the pressure on the movable mold 12. The device solves the problem that when the movable mold 12 contacts with the fixed mold 14 or the movable mold 12 returns to its original position, the movable mold 12 collides and produces a slight displacement, thereby improving the stability of the device and thereby improving the production quality of the plastic mold.
