However, due to the preciousness of the mold, the driving equipment will slow down when the movable mold approaches the fixed mold to prevent collision, so as to achieve the effect of protecting the mold. However, this will greatly prolong the mold connection time and have a great impact on the overall production efficiency. For this reason, we propose a split mold with a buffer function.

[0006] By adopting the above technical solution, the movable mold can be buffered while the movable mold is connected quickly to the fixed mold, which not only ensures the connection speed but also plays a protective effect on the mold.

[0007] The utility model is further configured such that the buffer assembly includes a sleeve fixed at the bottom end of the horizontal plate, and the interior of the sleeve is sleeved with a sleeve rod slidably connected to the inner wall of the sleeve, the bottom end of the sleeve rod is spaced apart from the end face of the bottom plate, and the top end of the sleeve rod is fixedly connected with a first piston plate slidably and sealingly connected to the inner wall of the air cavity, an air cavity is opened inside the sleeve, and the air cavity is filled with air to achieve buffering.

[0015] In summary, the utility model mainly has the following beneficial effects:

[0016] 1. The utility model provides a buffer assembly. When the movable mold 2 moves toward the fixed mold 1, the sleeve rod 8 moves relatively toward the sleeve 7 and squeezes the air in the air cavity 10 inside the sleeve 7 through the first piston plate 11. The resistance generated by the compressed air is used to slow down the speed of the sleeve 8, i.e., the buffer effect. Therefore, the fast connection between the fixed mold 1 and the movable mold 2 can be completed without slowing down the driving source, i.e., the electric guide rail 4, and there will be no collision problem.

[0017] 2. The utility model provides a snap-fit ​​block, a snap-fit ​​groove, a snap-fit ​​rod and a limit groove. As the movement of the first piston plate 11 increases, the air pressure in the air cavity 10 will gradually increase until the first piston plate 11 moves to the limit position. At this time, the air pressure is greater than the maximum value of the pressure valve. Therefore, the gas will be discharged into the telescopic tube 12 through the pressure valve. Then, the gas is discharged into the cavity of the vertical plate 9 through the telescopic tube 12 to drive the second piston plate 13 to move and stretch the spring. After the second piston plate 13 moves, it will push the drive plate 14 to move and make the snap-fit ​​block 15 move to the sleeve rod 8. The locking block 15 is engaged in the locking groove 16 of the outer wall, thereby completing the limitation of the sleeve rod 8. Furthermore, after the mold production is completed, the electrically controlled air outlet valve will be opened. At this time, the air inside the vertical plate 9 and the sleeve 7 will be discharged, thereby resetting the second piston plate 13 to release the limitation of the sleeve rod 8. When the locking block 15 moves to the locking groove 16 to engage, the locking block 15 will squeeze the driven block 17 to move, and the driven block 17 will then push the moving plate 18 to move and stretch the spring. The movement of the moving plate 18 will drive the locking rod 19 to move to the limiting groove 20 to limit the sleeve 7. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0024] The following describes an embodiment of the utility model based on its overall structure.

[0025] A split mold with a buffer function, such as Figure 1-4As shown, it includes a fixed mold 1, a movable mold 2 for engaging with the fixed mold 1 is arranged above the fixed mold 1, and bottom plates 3 for fixing the fixed mold 1 are fixed to the outer walls of both sides of the fixed mold 1, and the bottom plates 3 are fixedly connected to the fixing objects by bolts, and two groups of electric guide rails 4 extending upward are installed on the top of the bottom plate 3, and the outer wall of each group of electric guide rails 4 is sleeved with a slider 5 adapted to the electric guide rail 4 and fixed to the outer wall of the movable mold 2, a cross plate 6 is fixed between the two groups of sliders 5, and a buffer assembly is installed at the bottom end of the cross plate 6;

[0026] Furthermore, in this embodiment, the buffer assembly includes a sleeve 7 fixed to the bottom end of the horizontal plate 6, and the sleeve 7 is sleeved with a sleeve rod 8 slidably connected to the inner wall of the sleeve 7, the bottom end of the sleeve rod 8 is spaced from the end surface of the bottom plate 3, and the top end of the sleeve rod 8 is fixedly connected to a first piston plate 11 slidably and sealedly connected to the inner wall of the air cavity 10, the sleeve 7 is provided with an air cavity 10, and the air cavity 10 is filled with air to achieve buffering;

[0027] Specifically, when the movable mold 2 moves toward the fixed mold 1, the sleeve rod 8 will move relatively toward the sleeve 7 and squeeze the air in the internal air cavity 10 of the sleeve 7 through the first piston plate 11, and the resistance generated by the compressed air is used to slow down the speed of the sleeve 8, that is, the buffer effect. Therefore, there is no need to slow down the driving source, that is, the electric guide rail 4, to complete the quick connection of the fixed mold 1 and the movable mold 2, and there will be no collision problem.

[0028] See also Figure 2-3 , an air inlet valve for air intake is provided at the top of the air cavity 10, and pressure valves for exhaust are provided on the outer walls of both sides of the air cavity 10, a telescopic tube 12 connected to the pressure valve is connected to the outer wall of the sleeve 7, and the telescopic tube 12 extends downward, and the end surface of the bottom plate 3 is located on both sides of the sleeve rod 8 and is equipped with vertical plates 9 with electric-controlled air outlet valves, and a cavity is provided inside the vertical plate 9, and the cavity is connected to the telescopic tube 12, and the inner wall of the vertical plate 9 is slidably sealed and connected to the second piston plate 13 connected to the inner wall of the vertical plate 9 through a spring, and the end of the second piston plate 13 is fixedly connected to a driving plate 14 extending to the outside of the sleeve rod 8, and a clamping block 15 is fixed to the outer wall of the driving plate 14, and a clamping groove 16 adapted to the clamping block 15 is provided on one side of the clamping block 15 and located on the outer wall of the sleeve rod 8;

[0029] In the above description, in this embodiment, the gas in the air cavity 10 is used to buffer the connection between the movable mold 2 and the fixed mold 1, and the gas discharged from the air cavity 10 can also be used to drive the clamping block 15 to clamp and limit the sleeve rod 8, thereby ensuring the stability of the connection of the movable mold 2;

[0030] Specifically, as the movement of the first piston plate 11 increases, the air pressure in the air cavity 10 will gradually rise until the first piston plate 11 moves to the extreme position. At this time, the air pressure is greater than the maximum value of the pressure valve, so the gas will be discharged into the telescopic tube 12 through the pressure valve, and then the gas is discharged into the cavity of the vertical plate 9 through the telescopic tube 12 to drive the second piston plate 13 to move and stretch the spring. After the second piston plate 13 moves, it will push the driving plate 14 to move and make the locking block 15 move to the locking groove 16 on the outer wall of the sleeve rod 8 to lock, thereby completing the limitation of the sleeve rod 8. Furthermore, after the mold production is completed, the electrically controlled air outlet valve will be opened. At this time, the air inside the vertical plate 9 and the sleeve 7 will be discharged, thereby resetting the second piston plate 13 to release the limitation of the sleeve rod 8.

[0031] See also Figure 4 A driven block 17 is slidably disposed inside the engaging groove 16, and a movable plate 18 is connected to the outer wall of the driven block 17 through a spring and is connected to the inner wall of the sleeve rod 8 for sliding reset. A clamping rod 19 extending to the outer wall of the sleeve rod 8 is fixedly connected to the outer wall of the movable plate 18, and a limiting groove 20 adapted to the clamping rod 19 is provided on one side of the clamping rod 19 on the inner wall of the sleeve 7;

[0032] In the above description, while the engaging block 15 limits the sleeve rod 8, the engaging block 15 also drives the driven block 17 to limit the sleeve 7 and thus complete the secondary limit of the connection state of the fixed mold 1 and the movable mold 2;

[0033] Specifically, when the engaging block 15 moves to engage in the engaging groove 16, the engaging block 15 will squeeze the driven block 17 to move, and the driven block 17 will then push the moving plate 18 to move and stretch the spring. The movement of the moving plate 18 will drive the engaging rod 19 to move to the limiting groove 20 to limit the sleeve 7.

[0034] The working principle of the utility model is as follows: when the movable mold 2 moves toward the fixed mold 1, the sleeve rod 8 will relatively move toward the sleeve 7 and squeeze the air in the air cavity 10 inside the sleeve 7 through the first piston plate 11, and the resistance generated by the compressed air is used to achieve the speed reduction of the sleeve 8, that is, the buffering effect. Therefore, the fast connection between the fixed mold 1 and the movable mold 2 can be completed without slowing down the driving source, that is, the electric guide rail 4, and there will be no collision problem.

[0035] Furthermore, as the movement of the first piston plate 11 increases, the air pressure in the air cavity 10 will gradually rise until the first piston plate 11 moves to the limit position. At this time, the air pressure is greater than the maximum value of the pressure valve, so the gas will be discharged into the telescopic tube 12 through the pressure valve, and then the gas is discharged into the cavity of the vertical plate 9 through the telescopic tube 12 to drive the second piston plate 13 to move and stretch the spring. After the second piston plate 13 moves, it will push the driving plate 14 to move and make the engaging block 15 move to the engaging groove 16 on the outer wall of the sleeve rod 8 to engage, thereby completing the limitation of the sleeve rod 8. Furthermore, after the mold production is completed, the electrically controlled air outlet valve will be opened. At this time, the air inside the vertical plate 9 and the sleeve 7 will be discharged, thereby resetting the second piston plate 13 to release the limitation of the sleeve rod 8.

[0036] In addition, when the engaging block 15 moves to engage in the engaging groove 16, the engaging block 15 will squeeze the driven block 17 to move, and the driven block 17 will then push the moving plate 18 to move and stretch the spring. The movement of the moving plate 18 will drive the engaging rod 19 to move to the limiting groove 20 to limit the sleeve 7.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model.
