Also, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

[0036] As Figures 1 to 3 shown, a color glue mold is provided with an upper side plate 1 and a lower side plate 2, and a pattern block 3 arranged between the upper side plate 1 and the lower side plate 2, the upper side plate 1, the lower side plate 2 and the pattern block 3 enclosing a space for storing a tire to be vulcanized; the inner surface of the upper side plate 1 and / or the lower side plate 2 is further provided with a first recess 40, and the first recess 40 is provided with a removable type block 4; the inner surface of the removable type block 4 is further provided with a plurality of second recesses 50, and the second recesses 50 are provided with color glue 5 for forming colored characters and / or colored patterns on the surface of the tire.

[0037] The inner surface of the removable type block 4 and the inner surface of the color glue 5 arranged thereon protrude from the inner surface of the upper side plate 1 or the lower side plate 2 and are located in the space enclosed by the upper side plate 1, the lower side plate 2 and the pattern block 3. Alternatively, the inner surface of the removable type block 4 and the inner surface of the color glue 5 arranged thereon are aligned with the inner surface of the upper side plate 1 or the lower side plate 2 and form part of the inner surface of the upper side plate 1 or the lower side plate 2.

[0038] The detachable movable type block 4 is fixed to the upper side plate 1 and / or the lower side plate 2 by connecting screws 41.

[0039] The inner surface of the detachable movable type block 4 is also provided with a coating 6, which includes multiple layers of polytetrafluoroethylene (PTFE) sintered and cured layers, each layer having a thickness of 10 to 15 micrometers.

[0040] The total thickness of the coating 6 is 50 to 60 micrometers.

[0041] The bottom of the second groove 50 is also provided with several decorative lines 61.

[0042] like Figure 7 As shown, the detachable movable type block 4 is also provided with several spring conical positioning holes 70.

[0043] According to a colored rubber mold of this application, the upper side plate 1, the lower side plate 2, and the tread block 3 enclose a space for storing a tire to be vulcanized. The tread block 3 corresponds to the tire crown, and the upper side plate 1 and the lower side plate 2 correspond to the tire sidewall. The inner surface of the detachable type block 4 and the inner surface of the colored rubber 5 disposed thereon protrude from the inner surface of the upper side plate 1 or the lower side plate 2 and are located within the space enclosed by the upper side plate 1, the lower side plate 2, and the tread block 3, forming a recessed colored type block, that is, the colored lettering or pattern on the tire is recessed into the tire surface. The inner surface of the detachable type block 4 and the inner surface of the colored rubber 5 disposed thereon are aligned with the inner surface of the upper side plate 1 or the lower side plate 2 and constitute a part of the inner surface of the upper side plate 1 or the lower side plate 2, forming a protruding colored type block, that is, the colored lettering or pattern on the tire is protruding from the tire surface.

[0044] According to a colored adhesive mold of this application, the inner surface of the detachable type block 4, including the inner surface of the second groove 50, is coated with a coating 6. This coating is applied by surface spraying to increase adhesion, and in this embodiment, it is also referred to as the type block surface TFL coating process. The main component of the coating is polytetrafluoroethylene (PTFE). A multi-layer spraying process is used, with each layer being 10–15 micrometers thick. The coating is sintered and cured at 380–400°C. The cross-cut test (ASTM D3359) requires a grade ≥4B. The best adhesion effect for the pattern is achieved when the spraying thickness is 50–60 micrometers.

[0045] The bottom of the second groove 50 is also provided with several decorative lines 61, which are also referred to as the special processing technology of movable type block IDLG in this application embodiment. The adhesion of color glue is increased by the decorative lines at the bottom of the groove.

[0048] According to the color glue mold of the present application, the detachable movable type block 4 is further provided with a plurality of spring cone positioning holes 70, which are also referred to as THK positioning structures in the embodiments of the present application. By providing the positioning structure in the mold, it is ensured that the color rubber pattern can be smoothly implanted into the movable type block groove.

[0049] Figure 8 The THK positioning structure according to the embodiments of the present application and the color mark implantation time when the THK positioning structure is not used are compared in the table. Test group A pattern content: 8848; test group B pattern content: AL808; test group C pattern content: ALL-RIGHT; test group D pattern content: GF-ARSR EVER; and test group E pattern content: GF-ARSR EVER FORCE. Test results show that the color mark implantation time when the THK positioning structure is used is superior to that when the THK positioning structure is not used.

[0050] According to the color glue mold of the present application, a mold with a three-dimensional spatial structure is formed, which can form a color mark with a hollow shape and can fill other color glue in the hollow color mark or a color mark with a fluorescent function, thereby solving the problems of poor color glue forming quality and demolding difficulty.

[0051] By adding a coating or performing special treatment on the inner surface of the mold, the adhesion of the color glue is increased, and the firmness and definition of the pattern are further improved.

[0052] By providing the positioning structure in the mold, it is ensured that the color rubber pattern can be smoothly implanted into the movable type block groove.
