[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1-5 The present invention provides a mold release agent spraying device, including a bottom frame 5, a walking mechanism fixedly connected to the bottom of the bottom frame 5, a top frame 11 fixedly connected to the top of the bottom frame 5, a stabilizing part provided inside the top frame 11, a horizontally arranged horizontal connecting rod 13 fixedly connected to the middle of the outer side wall of the top frame 11, a lifting part fixedly connected to the other end of the horizontal connecting rod 13, and a mold release agent spraying mechanism fixedly connected to the bottom end of the lifting part.

[0032] The mold release agent spraying mechanism includes a vertically arranged support plate 15. The top end of the support plate 15 is fixedly connected to the bottom end of the lifting part. The support plate 15 is provided with two vertically symmetrically arranged spacing adjustment parts. The end of the spacing adjustment part away from the support plate 15 is fixedly connected to the mold release agent spraying part, and the side of the mold release agent spraying part away from the spacing adjustment part is fixedly connected to the rubber residue cleaning part.

[0033] The release agent spraying unit further optimizes the design by including a fixed platform 17, which is fixedly connected to the end of the spacing adjustment unit. The fixed platform 17 has through slots 24 in the middle of its top and bottom ends. Each through slot 24 is rotatably connected to two atomizing nozzles 25 spaced apart. The fixed platform 17 has two vertically arranged cavities 26 inside, which correspond one-to-one with the through slots 24 and are connected to the through slots 24 through a connecting hole 32. The two atomizing nozzles 25 in the same through slot 24 are connected to an angle adjustment unit, which is fixedly installed in the cavity 26.

[0034] Further optimization of the design includes a third motor 27, which is fixedly installed inside the cavity 26. The output shaft of the third motor 27 is fixedly connected to one end of a horizontally arranged bidirectional threaded screw 28, and the other end of the bidirectional threaded screw 28 is rotatably connected to the side wall of the cavity 26. The threads on both sides of the midpoint of the bidirectional threaded screw 28 have opposite directions of rotation. The two ends of the bidirectional threaded screw 28 are respectively threaded to a slide 29. One end of the slide 29 slides in contact with the wall of the cavity 26, and the other end of the slide 29 is fixedly connected to a second rack 30. The end of the atomizing nozzle 25 is fixedly connected to a semi-circular gear 31, which meshes with the second rack 30.

[0035] By adjusting the included angle between the two atomizing nozzles 25 within the same through slot 24, the coverage area of ​​the sprayed release agent can be adjusted, thereby ensuring that the entire inner wall of the mold is coated with release agent. When adjusting the included angle, the third motor 27 drives the bidirectional threaded screw 28 to rotate. Since the threads at both ends of the bidirectional threaded screw 28 rotate in opposite directions, when the bidirectional threaded screw 28 rotates in the same direction, the two slides 29 can move closer or further apart. When the slides 29 move closer or further apart, the meshing action of the second rack 30 and the semi-circular gear 31 can adjust the included angle between the two atomizing nozzles 25, thereby adjusting the coverage area of ​​the release agent.

[0036] In a further optimized design, the spacing adjustment unit includes a second motor 19. The second motor 19 is fixedly connected to the side wall of the support plate 15 away from the fixed platform 17. The output end of the second motor 19 is fixedly connected to one end of a vertically arranged lead screw 20. The other end of the lead screw 20 is rotatably connected to a fixed seat 22. The fixed seat 22 is fixedly connected to the side wall of the support plate 15. The two fixed seats 22 are close to each other. A slider 21 is threadedly connected to the lead screw 20. The side wall of the slider 21 slides in contact with the side wall of the support plate 15. One end of the slider 21 near the fixed platform 17 is fixedly connected to a telescopic part. The other end of the telescopic part passes through the strip hole 23 opened on the support plate 15 and is fixedly connected to the fixed platform 17.

[0037] The design is further optimized so that the telescopic part includes a horizontally arranged second telescopic rod 16. One end of the second telescopic rod 16 is fixedly connected to the side wall of the slider 21, and the other end of the second telescopic rod 16 passes through the strip hole 23 opened on the support plate 15 and is fixedly connected to the fixed platform 17.

[0038] The distance between the two fixed platforms 17 is adjusted according to the type of mold to be sprayed. When the mold is a single-cavity mold, the distance between the two fixed platforms 17 is reduced, and then the fixed platforms 17 are controlled to extend into the mold. Then, the top of the upper fixed platform 17 sprays out the release agent, while the bottom of the lower fixed platform 17 sprays out the release agent. When the mold is a double-cavity mold, the distance between the two fixed platforms 17 is increased, and then the upper fixed platform 17 extends into the upper cavity of the double-cavity mold, and the lower fixed platform 17 extends into the lower cavity of the double-cavity mold. The top and bottom of the two fixed platforms 17 spray out the release agent simultaneously.

[0039] The solution is further optimized so that the rubber residue cleaning part includes a high-pressure jet head 18, which is fixedly connected to the side wall of the fixed platform 17 away from the second telescopic rod 16. The top and bottom ends of the high-pressure jet head 18 are respectively provided with jet ports.

[0040] As the high-pressure jet nozzle 18 enters the mold along with the fixed platform 17, it continuously sprays high-pressure gas to form an air knife, which cleans away the rubber residue adhering to the inner wall of the mold.

[0041] The design is further optimized. The walking mechanism includes a first motor 8, which is fixed inside the base frame 5 by a fixing rod 7. The output shaft of the first motor 8 is fixedly connected to a gear 9, which meshes with a first rack 4. The first rack 4 is fixedly connected to the middle groove 2 opened at the top center of the guide rail seat 1. The four corners of the bottom end of the base frame 5 are respectively rotatably provided with walking wheels 6, which are rolled in the guide rail grooves 3 opened on both sides of the top of the guide rail seat 1.

[0042] The first motor 8 drives the gear 9 to rotate, and the gear 9 drives the entire device to move through the meshing action of the first rack 4.

[0043] The design was further optimized, and the stabilizing part includes a counterweight 12, which is fixedly embedded in the top frame 11.

[0044] The counterweight 12 improves the stability of equipment operation.

[0045] The scheme is further optimized. The lifting part includes a first telescopic rod 14, which is set vertically. The fixed end of the first telescopic rod 14 is fixedly connected to the end of the horizontal connecting rod 13 away from the top frame 11, and the telescopic end of the first telescopic rod 14 is fixedly connected to the top of the support plate 15.

[0046] The first telescopic rod 14 extends and retracts to different lengths to adjust the height of the fixed platform 17, ensuring that the fixed platform 17 can enter the mold at different heights and improve the applicability of the equipment.

[0047] The design is further optimized so that the bottom of the four corners of the top of the bottom frame 5 is fixedly connected to the bottom of the vertically set uprights 10, and the tops of the four uprights 10 are fixedly connected to the bottom of the top frame 11.

[0048] Reference Figure 6 When applying release agent to a single-cavity mold, the release agent is sprayed from the top of the upper fixed platform 17 to cover the surface of the upper mold 33, and the release agent is sprayed from the bottom of the lower fixed platform 17 to cover the surface of the lower mold 34.

[0049] Reference Figure 7 When applying release agent to the double-cavity mold, the upper fixed platform 17 extends between the upper mold 33 and the middle mold 35, and release agent is sprayed from both the top and bottom of the fixed platform 17 to cover the surface of the upper mold 33 and the top surface of the middle mold 35. The lower fixed platform 17 extends between the middle mold 35 and the lower mold 34, and release agent is sprayed from both the top and bottom of the fixed platform 17 to cover the bottom surface of the middle mold 35 and the surface of the lower mold 34.

[0050] The working process of this invention is as follows:

[0051] First, the first motor 8 is controlled to operate, driving the gear 9 to rotate. Through the meshing of the gear 9 and the first rack 4, the entire device is moved to the position of the mold to be sprayed with release agent. Then, the atomizing nozzle 25 is connected to the release agent storage container (not shown in the figure), and the high-pressure jet nozzle 18 is connected to the high-pressure gas source (not shown in the figure). Next, the first telescopic rod 14 is controlled to extend and retract a certain length to ensure that the two fixed platforms 17 can simultaneously extend into the mold to spray the release agent. Then, the second telescopic rod 16 is controlled to extend, driving the fixed platforms 17 and the high-pressure jet nozzle 18 to gradually enter the mold. During the entry process, the high-pressure jet nozzle 18 sprays high-pressure gas to clean the residual rubber on the inner wall of the mold. At the same time, the atomizing nozzle 25 sprays atomized release agent to cover the inner wall of the mold. After the spraying is completed, the second telescopic rod 16 is shortened, driving the fixed platforms 17 and the high-pressure jet nozzle 18 to move out of the mold.

[0052] When the mold to be sprayed is a single-cavity mold, the second motor 19 is controlled to work, driving the two fixed platforms 17 to move closer to each other, reducing the distance between the two fixed platforms 17, and then the two fixed platforms 17 are simultaneously inserted into the single-cavity mold. During spraying, only the top of the upper fixed platform 17 and the bottom of the lower fixed platform 17 are sprayed with release agent.

[0053] When the mold to be sprayed is a double-cavity mold, the second motor 19 is controlled to work, driving the two fixed platforms 17 to move away from each other, increasing the distance between the two fixed platforms 17. The upper fixed platform 17 extends into the upper cavity, and at the same time, the top and bottom ends are sprayed with release agent. The lower fixed platform 17 extends into the lower cavity, and at the same time, the top and bottom ends are sprayed with release agent.
