[0038] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0039] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless otherwise explicitly stated in the present invention, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof;

[0040] For the convenience of description, if the words "up", "down", "left" and "right" appear in the present invention, they only indicate that they are consistent with the up, down, left and right directions of the drawings themselves, and do not limit the structure. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0041] As introduced in the background technology, the shortcomings in the prior art exist. In order to solve the above technical problems, the present invention proposes a spring air hole sleeve device and a tire mold that can be cleaned without disassembly.

[0042] In a typical embodiment of the present invention, Figure 1 As shown, the spring pore sleeve device disclosed in this embodiment that can be cleaned without disassembly includes a spring pore sleeve and a protective device, and the spring pore sleeve includes a sleeve core 1, a spring 2, and a sleeve shell 3; the sleeve core 1 and the sleeve shell 3 are set together, and the sleeve shell 3 is inlaid on the mold, and one end of the sleeve core 1 has a notch 1-1, and the position of the notch 1-1 at least partially protrudes from the outside of the sleeve shell 3, and the other end of the sleeve core 1 is a limit end 1-2, and the sleeve shell 3 clamps the limit end 1-2. The spring 2 is sleeved on the shaft of the sleeve core 1, and one end of the spring 2 abuts against the lower end of the inner cavity of the sleeve shell 3, and the other end abuts against the limit end 1-2 of the sleeve core 1. Under the elastic force of the spring 2, the sleeve core 1 and the sleeve shell 3 have an exhaust gap at the shaft end. Further, the above-mentioned notch 1-1 style includes but is not limited to annular grooves, points, strips, through grooves, blind holes, threads, etc.

[0043] Furthermore, the protective device in this embodiment can close the exhaust gap to prevent impurities from entering. After the surface treatment, the protective device can be removed and the exhaust gap can be opened. There is no need to remove the sleeve core / the entire pore sleeve in order to prevent impurities from entering. Figure 2 As shown, it includes an opening and closing locking member 4, a rotating adjusting member 5, a spring 6, a tensioning member 7, a disassembly wrench 8, etc. The opening and closing locking member 4 is used to cooperate with the above-mentioned notch 1-1 to lock or loosen the sleeve core 1; by rotating the rotating adjusting member 5, it can be adjusted whether the opening and closing locking member 4 locks or loosens the sleeve core 1, that is, the rotating adjusting member 5 is a control member, and the rotating adjusting member 5 is specifically controlled by the disassembly wrench 8. When the rotating adjusting member 5 is rotated to a certain position, the opening and closing locking member 4 can be stretched open, otherwise, the opening and closing locking member 4 is locked; the spring 6 is used to connect the rotating adjusting member 5 and the tensioning member 7, the tensioning member 7 is fixed on the back of the mold or in the countersunk hole, preferably the countersunk hole is processed on the back of the mold, and the tensioning member is fixed in the countersunk hole, which does not affect the placement of the mold. In addition, by setting countersunk holes of different depths, the distance between the spring pore sleeve and the countersunk hole can be unified, which is conducive to the standardization of the length of the device.

[0044] Further, such as Figure 4 , Figure 5 As shown, in this embodiment, the opening and closing locking member 4 is a circumferentially discontinuous open slot structure, and its inner cavity side wall has a limiting protrusion 4-1, which can be stuck in the notch 1-1 of the sleeve core 1, and a through hole 4-2 is arranged at the bottom of the opening and closing locking member 4; the through hole cooperates with the connecting shaft of the rotating adjustment member 5 below, so that the head of the rotating adjustment member 5 can extend into the opening and closing locking member 4. The reason why the opening and closing locking member 4 is designed as a discontinuous structure in the circumference is mainly to enable the rotating adjustment member 5 to rotate inside it, and the long axis of the head of the rotating adjustment member 5 can extend from the side of the opening and closing locking member 4.

[0045] It should be further explained that the opening and closing locking member 4 needs to have a certain elasticity. Therefore, the opening and closing locking member 4 in this embodiment is made of an elastomeric material, including but not limited to elastomeric materials such as metal, plastic, and rubber.

[0046] It should be further explained that the above-mentioned limiting protrusion 4-1 can also be set as a limiting groove, and the corresponding notch 1-1 is set in the form of a protrusion.

[0047] Further, such as Figure 7 , Figure 8As shown, the rotary adjustment member 5 in this embodiment includes a head portion 5-1 and a tail portion 5-2, wherein the head portion 5-1 and the tail portion 5-2 are connected via a connecting shaft; wherein, in this embodiment, the head portion 5-1 is an elliptical cam, and since it is an elliptical cam, it has a major axis and a minor axis, and when the major axis is at the circumferential notch of the opening and closing locking member 4, the limiting protrusion 4-1 of the opening and closing locking member 4 and the notch 1-1 of the sleeve core 1 are in a closed state; when the major axis rotates to the side wall where the limiting protrusion 4-1 of the opening and closing locking member 4 is located, the opening and closing locking member 4 is opened by the head portion 5-1, and the limiting protrusion 4-1 of the opening and closing locking member 4 and the notch 1-1 of the sleeve core 1 are in a loose state; the connecting shaft cooperates with the through hole 4-2 at the bottom of the opening and closing locking member 4, and the connecting shaft extends out of the through hole 4-2 at the bottom of the opening and closing locking member 4 and is connected to the tail portion 5-2, and the connecting shaft and the tail portion 5-2 can be glued or mechanically connected.

[0048] Of course, it is not difficult to understand that the shape of the above-mentioned head 5-1 is not limited to the elliptical cam disclosed in this embodiment, and it can also be other irregular non-spherical shapes. However, no matter what shape it is, it is required to be able to open the above-mentioned opening and closing locking member 4 after rotating a certain angle.

[0049] Furthermore, in this embodiment, the tail portion 5 - 2 is a block structure.

[0050] It should be further explained that the above-mentioned rotation adjustment member 5 pushes the opening and closing locking member 4 in a manner including but not limited to a cam mechanism, a connecting rod mechanism, a spring mechanism, etc.

[0051] Furthermore, the tensioning member 7 in this embodiment is as follows: Figure 6 As shown, it is a columnar structure with a through hole in the middle. A limiting portion 7-1 is set at one end of the columnar structure close to the back of the mold. The diameter of the limiting portion 7-1 is larger than the diameter of the columnar body, so the limiting portion 7-1 can be against the back of the mold or in the countersunk hole.

[0052] Furthermore, in this embodiment, the above-mentioned spring 6 is connected between the tail 5-2 of the rotating adjustment member 5 and the tensioning member 7; in order to achieve the connection between the two, a limiting structure can be processed on the tail 5-2 of the rotating adjustment member 5 and the tensioning member 7, and the spring 6 can be clamped on the limiting structure, or the spring 6 can be welded / glued to the tail 5-2 of the rotating adjustment member 5 and the tensioning member 7.

[0053] It should be further explained that the material of the spring 6 includes but is not limited to metal, plastic, rubber and other elastomeric materials. Of course, it is not difficult to understand that the spring 6 can also be arranged between the opening and closing locking member 4 and the tensioning member 7. The arrangement method refers to the arrangement method of the tail 5-2 of the rotating adjustment member and the tensioning member 7, which will not be repeated here.

[0054] Further, such as Figure 3As shown in the structural schematic diagram of the above-mentioned disassembly wrench 8, the top end of the disassembly wrench 8 cooperates with the bottom of the rotating adjustment member 5, and the two are structures that can be combined and rotated together. Therefore, a straight-shaped or cross-shaped groove, for example, can be set at the bottom of the rotating adjustment member 5, or it can be directly set to a hexagonal shape, etc.

[0055] Based on the above device, the locking, sealing and resetting process of the spring pore sleeve in this embodiment is as follows:

[0056] On the back of the mold, insert the disassembly wrench into the inner hole of the tensioning member 7, push the rotating adjustment member 5 and the opening and closing locking member 4 into the air hole, and the top of the opening and closing locking member 4 is squeezed outward by the tail end of the sleeve core 1 and separated along the opening part, and continues to move upward, and the limiting protrusion 4-1 of the opening and closing locking member 4 is stuck with the notch 1-1 of the sleeve core 1, and then the opening and closing locking member 4 is deformed and restored, and locked with the notch of the sleeve core 1 (such as Fig.10 shown).

[0057] In actual use, the tail of the tensioning member 7 is against the back side / counter hole of the mold (such as Fig.11 As shown), one end of the spring 6 is connected thereto, and the other end applies tension to the sleeve core 1 by rotating the adjusting member 5 and the opening and closing locking member 4. At this time, the exhaust gap at the orifice of the air hole sleeve on the cavity surface is closed. In this state, the medium used for surface treatment, such as small particles of sand, detached rubber, or impurities after the surface adhesive scale is burned by the high temperature of the laser cleaning machine, will not enter the exhaust cavity of the spring air hole sleeve, and the surface of the cavity surface can be cleaned without disassembling the spring sleeve core or the spring sleeve.

[0058] After the surface treatment is completed, the rotary adjusting member 5 is driven to rotate by rotating the disassembly wrench 7, and the opening and closing locking member 4 is subjected to the tension of the connecting spring 6. The friction between the notch 1-1 of the sleeve core 1 and the opening and closing locking member 4 can prevent the opening and closing locking member 4 from rotating with the rotary adjusting member 5. The long end of the cam rotates to the clip of the opening and closing locking member 4 to open the opening and closing locking member 4, thereby releasing the locking state between the notched sleeve core 1 and the opening and closing locking member 4 (such as Fig. 9 As shown in the figure, the spring vent sleeve is reset by the spring force in the sleeve shell, the exhaust gap is opened, and the normal working state can be restored.

[0059] This embodiment also provides a tire mold, the tire mold comprising the above-mentioned spring air hole sleeve device that can be cleaned and removed without removal. Since the tire mold is provided with the above-mentioned spring air hole sleeve device that can be cleaned and removed without removal, the tire mold also has all the advantages mentioned above.

[0060] Embodiment 2

[0061] In this embodiment, another spring air hole sleeve device that can be cleaned without disassembly is provided, such as Fig.12As shown, in this embodiment, the tensioning member 7 in the first embodiment is eliminated, and a connecting spring 6 is sleeved on the outer side of the opening and closing locking member 4, one end of the connecting spring 6 abuts against the opening and closing locking member or the rotating adjusting member, and the other end abuts against the sleeve shell or the mold; the rest of the structure is exactly the same as that in the first embodiment, and will not be described in detail here.

[0062] The specific usage is as follows:

[0063] On the back of the mold, use a disassembly wrench 8 to push the rotary adjustment member 5 and the opening and closing locking member 4 into the hole. The top of the opening and closing locking member 4 is squeezed outward by the tail end of the sleeve core 1 and separated along the opening part, and locked with the notch 1-1 of the sleeve core 1. The connecting spring 6 is subjected to the pressure between the mold or the sleeve shell and the opening and closing locking member or the rotary adjustment member, and exerts a downward pulling force on the sleeve core 1. The exhaust gap at the air hole sleeve hole opening on the cavity surface is closed, and the surface treatment can be performed at this time.

[0064] The unlocking state is the same as in the first embodiment, and will not be described in detail here.

[0065] In addition, based on the spring pore sleeve device disclosed in this embodiment, this embodiment also provides a tire mold, and the tire mold includes the spring pore sleeve device that does not require cleaning and does not require disassembly. Since the tire mold is provided with the spring pore sleeve device that does not require cleaning and does not require disassembly, the tire mold also has all the advantages described above.

[0066] Finally, it should be noted that relational terms such as first and second are merely used to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any actual relationship or order between these entities or operations.
