[0018] The drawings are used to provide further understanding of the utility model, and constitute a part of the specification, are used together with the embodiments of the utility model to explain the utility model, and do not constitute the limitation of the utility model. DETAILED DESCRIPTION

[0019] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments; based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] like Figures 1-3 As shown in the embodiment of this utility model, a wear-resistant ball demolding device includes a lower fixed frame 1. In use, the lower fixed frame 1 is fixed on the lower mold 7. A floating ring 2 is provided on the lower fixed frame 1. The floating ring 2 can move up and down relative to the lower fixed frame 1 to accommodate wear-resistant balls of different diameters. Multiple sets of arc-shaped sliders 14 are rotatably provided on the floating ring 2. A rotating shaft 12 is horizontally hinged on the arc-shaped sliders 14. A rubbing roller 13 is provided on the rotating shaft 12. The rubbing roller 13 is driven to rotate by a motor 4. When the motor 4 drives the rubbing roller 13 to rotate, the rubbing roller 13 will rotate cyclically along the circumference of the floating ring 2 under the action of the arc-shaped sliders 14. While the rubbing roller 13 is rotating, it will roll and rub against the upper end of the ball 8 to be demolded in the lower mold 7, causing the ball 8 to be demolded to loosen between the ball 8 and the lower mold 7, so as to facilitate subsequent material removal.

[0022] To better adjust the position between the rubbing roller 13 and the ball 8 to be demolded, ensuring that the rubbing roller 13 and the ball 8 to be demolded are always tangent, multiple sets of guide positioning posts 5 are fixedly provided on the lower fixed frame 1. Multiple sets of connecting holes for connecting to the upper mold are provided on the edge of the lower mold 7. The lower end of the guide positioning post 5 is fixed in the connecting hole of the lower mold 7. The guide positioning post 5 can keep the lower fixed frame 1 relatively fixed and prevent it from rotating. The floating ring 2 is slidably provided on the guide positioning post 5. A spring 6 is provided on the guide positioning post 5 in the area between the floating ring 2 and the lower fixed frame 1. The floating ring 2, rubbing roller 13 and other components above the spring 6 compress the spring 6, making the rubbing roller 13 tangent to the ball 8 to be demolded. The spring 6 plays a role in buffering and supporting.

[0023] The top of the guide positioning column 5 is provided with a floating disk 3, that is, the floating disk 3 is located above the center of the lower fixed frame 1, and the motor 4 is located on the floating disk 3 above the center of the lower fixed frame 1.

[0024] like Figures 3-5 As shown, in order to drive the rubbing roller 13 to rotate, the end of the output shaft of the motor 4 is provided with a driving bevel gear 10, and the end of the rotating shaft 12 away from the arc-shaped slider 14 is provided with a driven bevel gear 11. The driven bevel gear 11 meshes with the driving bevel gear 10. When the motor 4 drives the driving bevel gear 10 to rotate, the driven bevel gear 11 drives the rotating shaft 12 to rotate, thereby causing the rubbing roller 13 to rotate.

[0025] In order to stabilize the rotating shaft 12, and at the same time, the rotating shaft 12 can both rotate to exert external force on the surface of the to-be-demoulded sphere 8, and revolve to make the rubbing roller 13 cyclically exert external force on all the to-be-demoulded spheres 8 in the lower mould 7, the output shaft of the motor 4 is provided with a rotating ring 9, the rotating ring 9 is arranged above the driving bevel gear 10, the part of the rotating shaft 12 protruding from the driven bevel gear 11 is hingedly arranged in the rotating ring 9, the rotating ring 9 and the arc-shaped sliding block 14 provide fulcrums for the two ends of the rotating shaft 12, and when the rotating shaft 12 rotates under the action of the driven bevel gear 11, it also revolves around the driving bevel gear 10, thereby cyclically exerting external force on the surface of all the to-be-demoulded spheres, so that better demoulding effect is achieved.

[0026] The floating ring 2 is provided with a sliding groove 15, the arc-shaped sliding block 14 is slidingly arranged in the sliding groove 15, the rubbing roller 13 is arrayed with protrusions, and the protrusions can increase the friction between the to-be-demoulded spheres 8, thereby improving the demoulding effect.

[0027] In use, the upper mould is removed from the lower mould 7, the to-be-demoulded spheres 8 in the lower mould 7 are leaked out, then the lower fixed frame 1 is placed on the lower mould 7, the lower end of the guide positioning column 5 is fixed in the connecting hole of the lower mould 7, and the lower fixed frame 1, the floating ring 2 and the floating disc 3 cannot rotate.

[0028] Under the action of the gravity of the upper floating ring 2, the floating disc 3 and other components, the spring 6 is compressed until the rubbing roller 13 is tangent to the upper end of each to-be-demoulded sphere 8, the height of the floating ring 2 and the floating disc 3 is relatively fixed, when the rubbing roller 13 moves to the area between each adjacent to-be-demoulded sphere 8, the spring 6 is compressed again, the floating ring 2 and the floating disc 3 also continue to move downward, but they will restore to the initial height again in the subsequent rotation, so that the floating ring 2 and the floating disc 3 form slight fluctuations in the height direction, and the spring 6 can effectively reduce the buffer.

[0029] Then the motor 4 is started, the motor 4 drives the rotating shaft 12 to rotate through the driving bevel gear 10 and the driven bevel gear 11, the rotating shaft 12 rotates and revolves around the driving bevel gear 10, thereby driving the rubbing roller 13 to rotate and revolve, the rubbing roller 13 reciprocatingly rotates along the circumferential direction of the floating ring 2 under the action of the arc-shaped sliding block 14, thereby exerting external force on each to-be-demoulded sphere 8 in the lower mould 7, so that the to-be-demoulded sphere 8 is loose with the lower mould 7, so as to be taken out subsequently.

[0030] It is to be noted that the relationship terms such as first and second, and the like, are used only to differentiate one entity or action from another, and do not necessarily require or imply any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0031] The above describes the utility model and its implementation, this kind of description is not limited, the embodiment shown in the drawing is only one of the utility model, the actual structure is not limited to this. In general if the ordinary skilled person in the art is inspired, without departing from the utility model creation tenet, not creative design the structure mode and example similar to this technical scheme, all should belong to the protection scope of the utility model.
