Description

Technical Field

[0001] The utility model relates to the technical field of electroplating devices, in particular to an electroplating device for a tire mold. Background Art

[0002] As the most critical sliding friction component in flexible tire molds, guide rings have long been the subject of intense research by tire mold manufacturers. The quality of the guide ring's friction surface machining determines the mold's flexibility. For example, the straightness and roundness of the guide ring's inner tapered surface determine smooth mold movement and prevent mold sticking. Some guide rings require electroplating on their inner tapered surfaces, so the quality of the plating layer determines the guide ring's service life and smooth movement.

[0003] As the existing devices are used, their shortcomings are gradually exposed, mainly in the following aspects:

[0004] First, since the inner cone of the guide ring is restricted by the fact that the guide ring has a variety of different sizes during the electroplating process, traditional electroplating tooling needs to be individually produced according to the guide ring structure. The process is relatively cumbersome, the structural rigidity is poor, and the production cost is high.

[0005] Second, the existing electroplating tooling is prone to deformation during repeated use, which affects the uniformity of the electrode arrangement, and thus affects the electroplating efficiency of the inner cone of the guide ring and the uniformity and density of the electroplating layer thickness.

[0006] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0007] In response to the defects in the existing technology, the utility model solves the problems in the traditional technology that the inner cone of the guide ring is restricted by the fact that the guide ring has a variety of different sizes during the electroplating process, and the traditional electroplating tooling needs to be individually produced according to the guide ring structure. The process is relatively cumbersome and the structural rigidity is poor, and the production cost is high; and the existing electroplating tooling is prone to deformation during repeated use, affecting the uniformity of the electrode arrangement, and thus affecting the electroplating efficiency of the inner cone of the guide ring and the uniformity and density of the thickness of the electroplating layer.

[0008] In order to solve the above problems, the present invention provides the following technical solutions:

[0013] As an optimized solution, the upper support ring and the lower support ring are both formed by welding split arc-shaped pieces.

[0014] As an optimized solution, the lower surface of the lower support ring of the electroplating tooling unit at the bottom is detachably connected to an inner hole electroplating circular ring.

[0015] As an optimized solution, the electroplating tooling unit at the bottom is connected to an insulating plate through a bolt assembly, and the guide ring is supported on the insulating plate.

[0028] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0029] like Figure 1 and Figure 2 As shown, the electroplating device for tire molds includes a conical electroplating tooling unit 1, wherein the electroplating tooling units 1 are provided with a plurality of electroplating tooling units 1 and are located in the same conical surface direction, and adjacent electroplating tooling units 1 are detachably arranged. The electroplating tooling units 1 include a plurality of grid electrodes 11 arranged along the conical surface direction.

[0030] The electroplating tooling unit 1 further includes an upper support ring 9 and a lower support ring 10 which are located in the same conical surface direction from top to bottom, and the grid electrode 11 is fixed on the upper support ring 9 and the lower support ring 10 .

[0031] The upper support ring 9 and the lower support ring 10 are located on the edge of the outer ring, and a positioning slot 12 is provided corresponding to each grid electrode 11. The grid electrode 11 is fixed in the positioning slot 12, which can effectively reduce the difficulty of assembly and welding during processing, thereby reducing costs. The spacing between the grid electrodes 11 is consistent, ensuring consistent current density in the later stage.

[0032] A plurality of positioning holes 5 are provided on the upper support ring 9 and the lower support ring 10 , and adjacent electroplating tooling units 1 are connected via tightening bolts 4 and the positioning holes 5 .

[0033] The upper support ring 9 and the lower support ring 10 are both formed by welding separate arc-shaped pieces, such as 1 / 4 arc.

[0034] The lower surface of the lower support ring 10 of the lowest electroplating tooling unit 1 is detachably connected to an inner hole electroplating circular ring.

[0035] The electroplating tooling unit 1 at the bottom is connected to the insulating plate 6 via a bolt assembly 3 , and the guide ring 2 is supported on the insulating plate 6 .

[0036] The guide ring 2 is connected to an aluminum plate cathode 7 , and the electroplating tooling unit 1 is connected to an aluminum plate anode 8 .

[0037] An insulating pad is provided between the lower end of the guide ring 2 and the insulating plate 6 .

[0038] The guide ring 2 is sleeved on the outside of the electroplating fixture unit 1 , and a plating gap is provided between the guide ring 2 and the electroplating fixture unit 1 .

[0039] The plurality of electroplating tooling units 1 are numbered so as to facilitate rotation of the unit number segments within a corresponding range according to the height and diameter of the guide ring 2 .

[0040] The working principle of this device is:

[0041] When it is necessary to electroplate the inner cone of the guide ring 2, the unit number segment of the universal electroplating tooling to be used is selected according to the height and diameter of the guide ring 2. The adjacent electroplating tooling units 1 are connected by tightening bolts 4 and positioning holes 5 and assembled in sequence, which can effectively ensure the concentric position relationship between the units. The positioning holes 5 are also used to rigidly connect the tooling and the guide ring 2 using the insulating plate 6 to ensure that the spacing between the electroplating tooling unit 1 and the guide ring 2 is consistent. In addition, the spacing between the grid electrodes 11 of each tooling unit is consistent, so that during the electroplating process, the current density passing through the guide ring 2 is uniform. The distance between the lowest electroplating tooling unit 1 and the insulating plate 6 can be adjusted by the bolt assembly 3, and then the distance between the grid electrode 11 and the guide ring 2 can be adjusted to ensure the uniformity of the coating.
