[0024] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please refer to Fig. 1 and Figure 2As shown in the figure, a platen stroke control mechanism for a stretching die includes a housing 1. At the bottom of the inner cavity of the housing 1, three fixing components 5 are fixedly connected. At the left end of the housing 1, a stroke control component 2 is fixedly connected. At the upper end of the stroke control component 2, an air pump 6 is fixedly connected. The output end of the air pump 6 communicates with the inner cavity of the blanking component 3. In the middle of the top end of the housing 1, a die closing component 4 is fixedly connected. A collection cavity is provided at the front end of the housing 1, and a detector is provided at the front end of the housing 32.

[0026] In the specific implementation process of this solution, by setting the cooperation between the die closing component 4 and the blanking component 3 of the device, when stretching the die, the blanking component 3 of the device can make the stretched die be blown into the collection cavity of the device through the internal gas, thus reducing the situation of workers being scalded when taking the stretched die. Further, by setting the cooperation between the stroke control component 2 and the die closing component 4 of the device, the device can continuously stretch the die plate, which can improve its working efficiency while making the stretched die more uniform, thus avoiding the inaccurate feeding caused by the workers being too tired.

[0027] It should be noted that the die closing component 4, the air pump 6, the detector and the stroke control component 2 of the device are all controlled by a control board. The working principle of the control board is: sending data in the form of Bluetooth to the die closing component 4, the air pump 6, the detector and the stroke control component 2 of the device, so as to adjust their working frequencies and improve the production efficiency.

[0028] Further, please refer to 3. Figure 4 and Figure 5 As shown in the figure, the stroke control component 2 includes a support plate 21. The left end of the support plate 21 is fixedly connected to the middle of the right end of the housing 1. At the upper end of the support plate 21, a motor 22 is fixedly connected. Fixing plates 27 are fixedly connected to both the left and right ends of the housing 1. A second rotating wheel 28 is rotatably connected to the inner cavities of the two fixing plates 27. At the middle of the rear end of the housing 1, a U-shaped block 24 is fixedly connected. Adjusting components 26 are slidably connected to both the left and right sides of the front end of the U-shaped block 24. The outer surfaces of the two second rotating wheels 28 and the outer surfaces of the two first rotating wheels 262 are jointly wound and connected with two transmission belts 23. A plurality of die plates 25 are fixedly connected to the upper parts of the mutually approaching ends of the two transmission belts 23. The rear end of the right second rotating wheel 28 is fixedly connected to the output end of the motor 22 through a coupling.

[0029] The mold clamping assembly 4 includes a hydraulic cylinder 41. The bottom end of the hydraulic cylinder 41 is fixedly connected to the middle of the upper end of the housing 1. A connecting rod 42 is fixedly connected to the bottom end of the hydraulic cylinder 41. A connecting plate 43 is fixedly connected to the bottom end of the connecting rod 42. Three connecting rods 44 are fixedly connected to the bottom end of the connecting plate 43. The bottom ends of the three connecting rods 44 are all fixedly connected with mold clamping heads 45. The blanking assembly 3 includes an air chamber 31. The rear end of the air chamber 31 is fixedly connected to the rear part of the inner cavity of the housing 1. A spray head 32 corresponding to the three ejector pins 52 is fixedly connected to the front end of the air chamber 31. The two adjusting assemblies 26 include two housings 261. The inner surfaces of the two housings 261 are rotatably connected with a first rotating wheel 262. Two second springs 263 are fixedly connected to the inner cavities of the two housings 261. The bottom ends of the four second springs 263 are all fixedly connected to the upper end of the U-shaped block 24.

[0030] In the further implementation process of this solution, by setting the two device adjusting assemblies 26 fixedly connected to the front side of the upper end of the U-shaped block 24 to cooperate with the two device drive belts 23, when the three device mold clamping heads 45 stretch the mold plate 25, the two device drive belts 23 can rise or fall following the two device adjusting assemblies 26. Thus, while the device mold clamping heads 45 complete the mold stretching, it can effectively avoid the situation of dangerous accidents during manual stretching.

[0031] Furthermore, by setting detection heads on the upper parts of the outer surfaces of the three device spray heads 32, after the three device mold clamping heads 45 complete the stretching, the three device spray heads 32 can release the internal air through the detection heads, so that the stretched mold can be blown into the collection cavity at the front end of the device housing 1, thereby reducing the labor intensity of workers. Further, by setting three connecting rods 44 at the bottom end of the device connecting plate 43, when the device connecting rod 42 stretches downward, more molds can be stretched, thus improving its working efficiency. Further, by setting second springs 263 in the inner cavities of the two device adjusting assemblies 26, when installing or disassembling the two device drive belts 23, it can be more relaxed, which is convenient for the daily maintenance of maintenance personnel.

[0032] Furthermore, please refer to 5. The fixing assembly 5 includes a connecting plate 51. The bottom end of the connecting plate 51 is fixedly connected to the middle of the bottom wall of the inner cavity of the housing 1. A top pin 52 is fixedly connected to the upper end of the connecting plate 51. An adjusting plate 53 is clamped on the outer surface of the top pin 52. A telescopic tube 54 is fixedly connected to the upper end of the adjusting plate 53. A number of limiting blocks are arranged at one end of the two drive belts 23 close to each other. Springs are arranged on the inner surfaces of the three telescopic tubes 54.

[0033] In the further implementation process of this solution, a first spring is arranged on the inner surface of the telescopic pipe 54 of the device. Thus, when the device is stretched by the mold clamping head 45 of the device, the first spring inside it will descend. Then, when the stretching ends, the first spring, through its own resilience, will jack up the stretched mold, so as to cooperate with the three device nozzles 32. As a result, the stretched mold can enter the collection cavity arranged at the front end of the device housing 1. Further, by arranging limit blocks at one ends of the two device conveyor belts 23 that are close to each other, when the two device conveyor belts 23 transport a number of mold plates 25, the limit blocks can hold the mold plates 25, and then, after the mold is stretched, the stretched mold block is thrown away through the arc surface, so as to install the mold plate 25 for the next time. Further, by arranging a number of sliders at the bottom end of the second connecting plate 51, it is convenient for the operator to disassemble it when performing maintenance or replacement on it, thus saving the time for mold replacement and installation;

[0034] In addition, in this solution, the device motor 22, air pump 6, hydraulic cylinder 41, control board, detection head, and circuit connection are all conventional designs in the prior art, and this solution will not elaborate on them too much.

[0035] The working principle of this utility model is as follows: When the operator uses this device, first, the control parameters need to be adjusted through the control board. Further, the operator needs to install the mold plate 25 to be stretched on the upper part of one ends of the two device conveyor belts 23 that are close to each other. Subsequently, the hydraulic cylinder 41, air pump 6, motor 22, and detection head are started. Then, when the device hydraulic cylinder 41 is working, it will drive the first connecting rod 42 to descend. Then, when the first connecting rod 42 descends, it will drive the device first connecting plate 43 to descend. Then, when the device first connecting plate 43 descends, it will drive the three second connecting rods 44 to descend. Then, when the three device second connecting rods 44 descend, they will drive the mold clamping head 45 fixedly connected to their bottom ends to stretch the mold plate 25. During the process that the device mold clamping head 45 stretches the mold plate 25, the two device adjusting components 26 will rise or fall according to the stretching frequency, so that the device ejector pin 52 can jack up the mold. Thus, when the device mold clamping head 45 lifts after stamping, the spring arranged in the inner cavity of the device mold clamping head 45 will jack up the stretched mold, which is then detected by the detection head on the upper part of the outer surface of the nozzle 32, and then the gas in the inner cavity of the air chamber 31 is released, so that the stretched mold can be blown into the collection cavity at the front end of the device housing 1 to complete the collection.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present utility model.
