An oil spraying device for spraying a mold release agent inside the molding cavity 5 to facilitate the discharge of the molding cavity 5 is arranged between the inside of the rectangular opening and the liquid storage tank 7. In this embodiment, the shoe mold, hydraulic device, compressed air control device, feeding device, water vapor control device, cooling water control device and controller involved in the molding of popcorn soles are consistent with the existing popcorn sole molding equipment on the market in structure and function. This embodiment focuses on improving the problem that the manual spraying demoulding machine causes unevenness and requires additional wiping, which affects the production efficiency; In order to realize the function of lifting the movable plate 6, the spraying includes a movable plate 6 and a micro flow pump 23. The micro flow pump 23 is arranged inside the liquid storage tank 7. The movable plate 6 is slidably connected to the inner wall of the rectangular opening. A lifting driving structure for driving the movable plate 6 to lift is arranged between the movable plate 6 and the inner wall of the machine 1. When the lifting driving structure is at the end of the lower stroke, the upper wall of the movable plate 6 is flush with the upper wall of the machine 1. The lifting driving structure includes two groups of first cylinders 10. A group of side support plates 9 are fixedly connected to the inner upper wall of the machine 1 and are located on the left and right sides of the rectangular opening. The two groups of first cylinders 10 are fixedly connected to the inner upper wall of the machine 1 and are located on the left and right sides of the rectangular opening. A cylinder 10 is fixedly connected to the opposite side of the two groups of side support plates 9, and the ends of the extended shafts of the two groups of first cylinders 10 are fixedly connected to the lower wall of the movable plate 6. The movable plate 6 is driven to rise and fall by extending and retracting the shafts of the first cylinders 10. The two groups of first cylinders 10 drive the movable plate 6 to rise and fall, so that the movable plate 6 can be flush with the upper wall of the machine table 1 when the release agent does not need to be sprayed, and other processes of the popcorn forming machine are not affected. When the release agent needs to be sprayed, the first cylinder 10 extends the shaft to drive the movable plate 6 to rise for spraying; In order to maintain the stability of the movable plate 6 when it is lifted or lowered, a first guide structure for maintaining the stability of the movable plate 6 when it is lifted or lowered is provided between the lower wall of the movable plate 6 and the inner wall of the machine table 1. The first guide structure includes two groups of positive support plates 11 and four groups of first guide rods 12. The two groups of positive support plates 11 are fixedly connected to the inner upper wall of the machine table 1 and are respectively located on the front and rear sides of the rectangular opening. The opposite sides of the two groups of positive support plates 11 extend toward the center of the front and rear directions of the rectangular opening. The four groups of first guide rods 12 are slidably connected to the inner wall of one group of positive support plates 11 in pairs of two. The upper ends of the four groups of first guide rods 12 are fixedly connected to the lower wall of the movable plate 6. The four groups of first guide rods 12 are respectively close to the four corners of the lower wall of the movable plate 6. The axis of the first guide rod 12 is perpendicular to the upper wall of the machine table 1. Through the guiding effect of the four groups of first guide rods 12, the stability of the movement of the movable plate 6 can be maintained when it is lifted or lowered. In order to control the highest point of the movable plate 6, a threaded section 1201 is provided at one end of the first guide rod 12 away from the movable plate 6. The outer wall of the threaded section 1201 is threadedly connected to a limiting sleeve 21. The limiting sleeve 21 and the threaded section 1201 are locked and fixed by a nut. Different types of soles have different heights of the lower molding molds 4. The limiting sleeve 21 can control the highest stroke of the movable plate 6. The limiting distance can be adjusted by loosening the nut and rotating the limiting sleeve 21 to be suitable for lower molding molds 4 of different heights. At the same time, after limiting the upper movable stroke of the movable plate 6 by the limiting sleeve 21, the distance between the atomizing nozzle 19 and the inner surface of the molding cavity 5 can be accurately controlled to improve the atomization effect. In order to ensure the stability of the connecting strip 17 when it moves forward and backward, the lower wall of the movable plate 6 is distributed front and back and fixedly connected with the front fixing frame 22 and the rear fixing frame 13 in sequence. Two groups of fixing sleeves 15 are fixedly connected between the front fixing frame 22 and the opposite sides of the rear fixing frame 13. The rear side of the rear fixing frame 13 is slidably connected with the connecting strip 17 through a second guide structure. The second guide structure includes two groups of second guide rods 16. The two groups of second guide rods 16 are distributed left and right and are fixedly connected to the front wall of the connecting strip 17 in sequence. The ends of the two groups of second guide rods 16 away from the connecting strip 17 all penetrate the inner wall of the rear fixing frame 13 and are slidably connected to the inner side wall of a group of fixing sleeves 15 respectively. The guidance of the two groups of second guide rods 16 can maintain the stability of the connecting strip 17, the liquid storage box 18 and the atomizing nozzle 19 when they are driven by the second cylinder 14 to translate. In order to drive the spraying structure to move forward and backward uniformly so as to achieve the purpose of spraying the spraying structure on the inner wall of the molding cavity 5 to form a uniform release agent film, a translation driving structure for driving the connecting strip 17 to move forward and backward is provided between the connecting strip 17 and the rear fixing frame 13. The translation driving structure is a second cylinder 14. The second cylinder 14 is fixedly connected between the front fixing frame 22 and the rear fixing frame 13 and is located between the two sets of fixing sleeves 15. The end of the second cylinder 14 extending the shaft passes through the rear fixing frame 13 and is fixedly connected to the front wall of the connecting strip 17. The second cylinder 14 uses a common uniform speed cylinder on the market. The atomizing nozzle 19 is driven to move forward and backward by extending and retracting the shaft of the second cylinder 14. The moving process is very stable. In order to realize mechanical quantitative spraying, a spraying structure is arranged between the lower wall of the connecting strip 17 and the micro flow pump 23, and the spraying structure includes two groups of liquid storage boxes 18 and atomizing nozzles 19. The two groups of liquid storage boxes 18 are distributed on the left and right and are fixedly connected to the lower wall of the connecting strip 17 in sequence. An oil storage cavity is arranged inside the liquid storage box 18. The liquid storage box 18 and the micro flow pump 23 are connected through a spraying pipe 20. The two groups of atomizing nozzles 19 are respectively fixedly connected to the lower wall of a group of liquid storage boxes 18. The two groups of atomizing nozzles 19 are respectively aligned with a group of molding cavities 5 in the upper and lower directions under the front projection. Before the popcorn sole is formed, the micro flow pump 23 extracts the oil in the liquid storage tank 7. After the release agent is added, it is metered into the liquid storage box 18, and then sprayed out through the atomizing nozzle 19 by the pressure of the pump to form a uniform mist group, forming a uniform film on the inner surface of the molding cavity 5. The opening and closing time of the micro flow pump 23 can be controlled by a common travel switch on the market. Through simple tests, it can be achieved that the micro flow pump 23 is turned on when the atomizing nozzle 19 is located above the molding cavity 5. In order to avoid the dripping problem of the atomizing nozzle 19, the atomizing nozzle 19 can be moved to the rear end of the molding cavity 5 first, and sprayed from the back to the front, which can avoid the problem of excessive release agent in the molding cavity 5 caused by dripping during the return journey; In order to enable the spray pipe 20 to be retracted when the second cylinder 14 extends the shaft and retracts it, the spray pipe 20 is a spring hose, which can ensure that the spray pipe 20 also shrinks synchronously after the second cylinder 14 extends the shaft and retracts it, to avoid the subsequent movable plate 6 being stuck between the movable plate 6 and the rectangular opening when it descends.

[0020] Working principle: by driving the movable plate 6 up and down through two groups of first cylinders 10, the movable plate 6 can be flush with the upper wall of the machine platform 1 when there is no need to spray the release agent, and other processes of the popcorn forming machine are not affected. When the release agent needs to be sprayed, the first cylinder 10 extends the shaft to drive the movable plate 6 to rise for spraying; by the guiding effect of the four groups of first guide rods 12, the movable plate 6 can maintain the stability of the movement when it rises and falls. There is a problem of different heights of the lower forming molds 4 of different models of soles. The limit sleeve 21 can control the maximum stroke of the movable plate 6. By loosening the nut and rotating the limit sleeve 21, the limit distance can be adjusted to suit the lower forming molds 4 of different heights. At the same time, after limiting the upper movable stroke of the movable plate 6 by the limit sleeve 21, the distance between the atomizing nozzle 19 and the inner surface of the forming cavity 5 can be accurately controlled to improve the atomization effect. The guidance of the two groups of second guide rods 16 can keep the connecting strip 17, the liquid storage box 18 and the atomizing nozzle 19 driven by the second cylinder 14 to translate. The stability of the atomizing nozzle 19 is driven to move forward and backward by extending and retracting the shaft of the second cylinder 14, and the moving process is very stable; before the popcorn sole is formed, the mold release agent in the liquid reservoir 7 is extracted by the micro flow pump 23, and then measured and sent to the liquid storage box 18, and then sprayed through the atomizing nozzle 19 by the pressure of the pump to form a uniform fog group, forming a uniform film on the inner surface of the molding cavity 5. The opening and closing time of the micro flow pump 23 can be controlled by a common stroke switch on the market. Through a simple test, it can be achieved that the atomizing nozzle 19 is opened when it is located above the molding cavity 5. In order to avoid the dripping problem of the atomizing nozzle 19, the atomizing nozzle 19 can be moved to the rear end of the molding cavity 5 first, and sprayed in the form of spraying from the back to the front, which can avoid the problem of excessive mold release agent in the molding cavity 5 caused by dripping during the return journey; the spring hose can ensure that the spraying pipe 20 also shrinks synchronously after the extension shaft of the second cylinder 14 is retracted, so as to avoid the subsequent movable plate 6 being stuck between the movable plate 6 and the rectangular opening when it descends.
