[0026] The specific implementation methods of the present invention are described below in combination with the prior art and the accompanying drawings. These implementation methods are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. The present disclosure can be implemented in various forms and should not be limited by the implementation methods described herein.

[0027] like Figure 1 As shown, in the prior art, the hot mold 1 is placed on the ground through the support 2, and the spraying equipment 3 is provided with wheels at the bottom, which is movable, and the nozzle of the spraying equipment 3 can rotate 360 ​​degrees. The nozzle of the spraying equipment 3 is extended into the hot mold 1 to spray the release agent. When spraying the release agent, when the nozzle is spraying at the two end parts of the hot mold 1, in order to prevent insufficient spraying of the release agent at the end, it is necessary to make the nozzle slightly extend out of the end, and it is inevitable that a part of the release agent is sprayed out of the tube end, the sprayed release agent is wasted and the chemical substances in the release agent will pollute the air.

[0028] Example 1

[0029] The present embodiment is different from the prior art described above in that Figure 2 As shown, the hot mold spraying device has not only the spraying equipment 3, but also a collecting hood 4 which is arranged at both ends of the hot mold 1 and can move left and right.

[0030] Further Figure 3 As shown, the collecting hood 4 includes a walking base 41, a hood support portion 42 and a hood body 43. The hood support portion 42 is fixed to the upper portion of the walking base 41. The hood body 43 is connected to the hood support portion 42 through a through channel 44. A collecting barrel 45 is placed directly below the through channel 44. The hood body 43 covers the end of the hot mold 1. The spraying equipment 3 can spray a release agent on the hot mold 1 through the hood body 43.

[0031] Collecting hoods 4 are provided at both ends of the hot mold 1. When the spraying operation is performed, the two ends of the hot mold are covered, which not only avoids air pollution, but also can collect the release agent sprayed out of the hot mold tube end. Universal wheels are provided under the walking base 41. When driven or pushed by external force, the walking base 41 will carry the entire collecting hood 4 to move, so that the collecting hood 4 can be removed after the spraying preparation and spraying is completed, without affecting the placement of the hot mold.

[0032] The purpose of this embodiment is to use the cover body 43 to block the splashing release agent. The cover body support part 42 can be installed according to the support needs and general rigidity needs. It can be a steel structure bracket or a box structure. This embodiment provides a preferred non-enclosed box structure with a side opening. As shown in the figure, the collection bucket 45 can be placed through the opening on the inner side.

[0033] More specifically, the box-type structure is square and is formed by splicing a plurality of metal panels, and the through channel 44 is connected through the metal panel on the top of the box-type structure.

[0034] Next, combine Figure 4 In this embodiment, the cover body 43 is a circular shell structure formed by welding an outer plate 431, an annular plate 432 and an inner plate 433. A central hole larger than the outer diameter of the hot mold 1 is provided on the outer plate 431 and the inner plate 433, and the through channel 44 is connected to the bottom of the cover body 43. Preferably, the diameter of the central hole on the outer plate 431 and the inner plate 433 is 1.1-1.3 times the outer diameter of the hot mold 1.

[0035] In order to make the release agent in the cover body 43 gather at the middle position, as shown in the figure, this embodiment is also provided with a guide plate 434 inclined toward the center at the bottom position in the cover body 43. In order to make the release agent in the cover body 43 enter the cover body support part, the top of the through channel 44 in this embodiment is not higher than the inner surface of the bottom of the cover body 43.

[0036] Example 2

[0037] This embodiment is a substitute for the embodiment 1, in which the outer plate 431 of the cover body 43 disposed on the collecting cover 4 at one end away from the spraying device 3 in the embodiment 1 is set as a whole flat plate without a center hole. This structure is relatively simple and is not shown in the figure. Since the nozzle of the spraying device 3 does not need to pass through the outermost outer plate 431 of the collecting cover 4 disposed at one end away from the spraying device 3, it is also possible to set the outer plate 431 at this location as a whole flat plate, which improves the blocking effect of the release agent at this location to a certain extent.

[0038] Other advantages of this embodiment are the same as those of Embodiment 1.

[0039] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
