DETAILED DESCRIPTION

[0025] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 7 , the utility model provides a technical solution:

[0027] See also Figure 1-Figure 2 As shown, a water nozzle clamping structure of an injection molding machine with a robot clamping includes an injection molding machine 1, a fixed base plate 8 is installed on the top of the injection molding machine 1, a displacement cylinder 2 is installed on the top of the fixed base plate 8, a rotating cylinder 4 is arranged on one side of the telescopic end of the displacement cylinder 2, a bending arm 5 is connected to the driving end of the rotating cylinder 4, one end of the bending arm 5 is connected to a clamping cylinder 6, a mold 7 is arranged on one side of the fixed base plate 8, and the injection molding machine 1 is provided with a chamber 9.

[0028] The clamping cylinder 6 replaces the manual clamping of the water inlet to achieve the clamping work of the water inlet. The displacement cylinder 2 controls the accuracy of the left and right positions to achieve the left and right movement of the robot. The rotating cylinder 4 controls the accuracy of the front and back positions to achieve the front and back movement of the robot. Before the mold 7 works, the robot is completely reset and returns to the origin.

[0029] When the mold 7 starts to work and the mold is closed, the displacement cylinder 2 of the manipulator corrects the left and right positions under the action of thrust, and the rotating cylinder 4 corrects the front and rear positions under the action of thrust. After reaching the precise position, the clamping cylinder 6 clamps the water outlet under the action of thrust, and then the displacement cylinder 2 moves back first to disengage the water outlet, and then the clamping cylinder 6 starts to loosen the water outlet, so that the water outlet falls into the chamber 9, and then returns to the origin in sequence. The clamping of the water outlet is completed once, and then the work is repeated. This combined linkage of the displacement cylinder 2, the rotating cylinder 4 and the clamping cylinder 6 reduces labor costs and safety, and the movement is more efficient and accurate, thereby improving efficiency;

[0030] This method saves time compared to manually clamping the water outlet, thereby reducing costs, is safer, operates automatically, and improves efficiency. It can be used for clamping the water outlet of any injection molding machine 1 to improve the working efficiency of the injection molding machine 1.

[0031] See also Figure 1-Figure 2 The telescopic end of the displacement cylinder 2 is connected to a connecting block 3, and the rotating cylinder 4 is fixedly mounted on the outer wall of the connecting block 3.

[0032] The connecting block 3 is used to fix the rotating cylinder 4 and connect the rotating cylinder 4 to the telescopic end of the displacement cylinder 2. When the displacement cylinder 2 drives the connecting block 3, the rotating cylinder 4 can be driven to move. The connecting block 3 supports the rotating cylinder 4 more stably.

[0033] See also Figure 1-Figure 6 The inner wall of the chamber 9 is rotatably connected with a connecting rod 11, and two supporting rods 12 are fixedly installed on the outer wall of the connecting rod 11. An elastic cloth 13 is fixedly connected between the two supporting rods 12, and a return spring 21 is connected between one of the supporting rods 12 and the outer wall of the chamber 9.

[0034] When the nozzle falls from the clamping cylinder 6 into the chamber 9, due to the high height between the clamping cylinder 6 and the chamber 9, the nozzle collides with a hard object during the falling process, which may cause scratches, cracks or breaks. The elastic cloth 13 catches the falling nozzle, which plays a buffering role on the downward impact force of the nozzle.

[0035] When the water outlet hits the elastic cloth 13, due to the impact force, the elastic cloth 13 and the support rod 12 will swing downward, and at the same time, the support rod 12 will squeeze the reset spring 21, and the connecting rod 11 will rotate along the outer wall of the chamber 9. When the elastic cloth 13 tilts, the water outlet can slide into the chamber 9 along the elastic cloth 13, and then the reset spring 21 will push the support rod 12 and the elastic cloth 13 back to their original positions, making it convenient for the elastic cloth 13 to buffer the subsequent water outlets. The elastic force of the reset spring 21 is relatively small, so when the water outlet hits the elastic cloth 13, the elastic cloth 13 and the support rod 12 will swing downward.

[0036] See also Figure 3-Figure 5 The chamber 9 is provided with an arc-shaped slide groove 15 , wherein one of the support rods 12 is fixedly connected to a slide rod 20 , and one end of the slide rod 20 extends into the interior of the arc-shaped slide groove 15 .

[0037] Since the support rod 12 and the elastic cloth 13 swing around the connecting rod 11, the swing trajectory of the support rod 12 and the elastic cloth 13 is arc-shaped. When the support rod 12 swings downward, it will slide along the arc-shaped slide groove 15 through the slide rod 20. The arc-shaped slide groove 15 provides a guide for the support rod 12, making the support rod 12 more stable when swinging.

[0038] See also Figure 7A pressing plate 22 is arranged inside the arc-shaped slide groove 15 , and a buffer spring 10 is connected between the bottom of the pressing plate 22 and the inner bottom wall of the arc-shaped slide groove 15 .

[0039] When the slide rod 20 slides along the arc-shaped slide groove 15 and hits the pressure plate 22, the pressure plate 22 cooperates with the buffer spring 10 to buffer the slide rod 20. Because the elastic cloth 13 and the support rod 12 will swing downward quickly when the water outlet hits the elastic cloth 13, which will cause the slide rod 20 to quickly hit the arc-shaped slide groove 15. The pressure plate 22 and the buffer spring 10 buffer the force of the slide rod 20 to prevent the slide rod 20 from loosening and being damaged.

[0040] See also Figure 3 An inclined plate 14 is fixedly mounted on the outer wall of the chamber 9 , and the inclined plate 14 is inclinedly arranged on one side of the elastic cloth 13 . A collecting box 18 is arranged on one side of the chamber 9 .

[0041] After the water outlet slides down from the elastic cloth 13 , it will roll to one side of the inclined plate 14 , and then the water outlet will roll along the inclined plate 14 into the collecting box 18 , so that the water outlet can be collected by the collecting box 18 .

[0042] See also Figure 3 The injection molding machine 1 is provided with a slide rail 17 , and a slider 16 is fixedly installed on the outer wall of the collection box 18 . The slider 16 is located inside the slide rail 17 and is slidably connected to the slide rail 17 .

[0043] After the collecting box 18 is pulled, the collecting box 18 can slide along the slide rail 17 through the slider 16 to realize the mobility of the collecting box 18. In this way, when the water outlet in the collecting box 18 is full, the collecting box 18 can be pulled out to facilitate the removal of the water outlet.

[0044] See also Figure 4 A plurality of elastic ropes 19 are fixedly connected between the two support rods 12 , and the outer wall of the elastic rope 19 abuts against the bottom of the elastic cloth 13 .

[0045] The elastic rope 19 holds the bottom of the elastic cloth 13 so that when the water outlet falls and hits the connecting block 3, the connecting block 3 will not be knocked loose from the support rod 12, so that the elastic cloth 13 can better withstand the impact.

[0046] Working principle:

[0047] The clamping cylinder 6 replaces the manual clamping of the water inlet to achieve the clamping work of the water inlet. The displacement cylinder 2 controls the accuracy of the left and right positions to achieve the left and right movement of the robot. The rotating cylinder 4 controls the accuracy of the front and back positions to achieve the front and back movement of the robot. Before the mold 7 works, the robot is completely reset and returns to the origin.

[0048] When the mold 7 starts to work and the mold is closed, the displacement cylinder 2 of the manipulator corrects the left and right positions under the action of thrust, and the rotating cylinder 4 corrects the front and rear positions under the action of thrust. After reaching the precise position, the clamping cylinder 6 clamps the water outlet under the action of thrust, and then the displacement cylinder 2 moves back first to disengage the water outlet, and then the clamping cylinder 6 starts to loosen the water outlet, so that the water outlet falls into the chamber 9, and then returns to the origin in sequence. The clamping of the water outlet is completed once, and then the work is repeated. This combined linkage of the displacement cylinder 2, the rotating cylinder 4 and the clamping cylinder 6 reduces labor costs and safety, and the movement is more efficient and accurate, thereby improving efficiency;

[0049] This method saves time compared to manually clamping the water outlet, thereby reducing costs, is safer, operates automatically, and improves efficiency. It can be used for clamping the water outlet of any injection molding machine 1 to improve the working efficiency of the injection molding machine 1.

[0050] When the nozzle falls from the clamping cylinder 6 into the chamber 9, due to the high height between the clamping cylinder 6 and the chamber 9, the nozzle collides with a hard object during the falling process, which may cause scratches, cracks or breaks. The elastic cloth 13 catches the falling nozzle, which plays a buffering role on the downward impact force of the nozzle.

[0051] When the water outlet hits the elastic cloth 13, due to the impact force, the elastic cloth 13 and the support rod 12 will swing downward, and at the same time, the support rod 12 will squeeze the reset spring 21, and the connecting rod 11 will rotate along the outer wall of the chamber 9. When the elastic cloth 13 tilts, the water outlet can slide into the chamber 9 along the elastic cloth 13, and then the reset spring 21 will push the support rod 12 and the elastic cloth 13 back to their original positions, making it convenient for the elastic cloth 13 to buffer the subsequent water outlets. The elastic force of the reset spring 21 is relatively small, so when the water outlet hits the elastic cloth 13, the elastic cloth 13 and the support rod 12 will swing downward.
