After the upper mold 1 and the lower mold 2 are closed, a cavity 11 for vulcanizing the tire blank is formed. The upper mold 1 is fixedly sleeved on the upper mold 1, and an upper steam cavity 31 is formed between the upper insulation sleeve 3 and the upper mold 1; the lower insulation sleeve 4 is fixedly sleeved on the lower mold 2, and a lower steam cavity 41 is formed between the lower insulation sleeve 4 and the lower mold 2. The upper insulation sleeve 3 can reduce the heat loss of the upper mold 1, and the lower insulation sleeve 4 can reduce the heat loss of the lower mold 2, thereby reducing the heat loss in the cavity 11 and improving the production efficiency of the tire.

[0035] like Figure 2 and 3As shown, an upper partition 5 is provided inside the upper insulation sleeve 3, and the upper partition 5 is located in the upper steam cavity 31. One side of the upper partition 5 is fixedly connected to the outer wall of the upper mold 1, and the other side is fixedly connected to the inner wall of the upper insulation sleeve 3. A first positioning member is provided on the upper partition 5, and the first positioning member is a first positioning pin 51. A first positioning hole 32 is provided on the upper insulation sleeve 3, and the first positioning pin 51 passes through the first positioning hole 32 and is fixedly connected to the upper partition 5. An upper steam inlet 33 is provided on one side of the opening of the first positioning hole 32, and an upper steam outlet 34 is provided on the other side and near the bottom of the upper insulation sleeve 3. The upper steam inlet 33 and the upper steam outlet 34 are both connected to the upper steam cavity 31. When it is necessary to install the upper partition 5 and the upper insulation sleeve 3, after moving the upper partition 5 to a suitable position, move the first positioning pin 51 so that the first positioning pin 51 passes through the first positioning hole 32 and is fixedly connected to the upper partition 5. At this time, the upper partition 5 and the upper insulation sleeve 3 are relatively positioned to facilitate the fixed installation of the upper partition 5, so that steam can enter from the left side of the upper partition 5 and flow out from the right side of the upper partition 5. In actual operation, after closing the upper mold 1 and the lower mold 2, steam is injected into the upper steam inlet 33 through a pipeline, and the steam enters the upper steam cavity 31 from the left side of the upper partition 5, and flows out of the upper steam outlet 34 from the right side of the upper partition 5. The steam is sucked out from the upper steam outlet 34 through a pipeline, so that the upper insulation sleeve 3 can be heated and insulated, thereby facilitating the heating and insulation of the upper mold 1, reducing the impact of temperature changes on the tire production process.

A second positioning member is provided on the lower baffle 6, and the second positioning member is a second positioning pin 61. A second positioning hole 42 is provided on the lower insulation sleeve 4, and the second positioning pin 61 passes through the second positioning hole 42 and is fixedly connected to the lower baffle 6. A lower steam inlet 43 is provided on one side of the opening of the second positioning hole 42, and a lower steam outlet 44 is provided on the other side. Both the lower steam inlet 43 and the lower steam outlet 44 are connected to the lower steam cavity 41. When it is necessary to install the lower baffle 6 and the lower insulation sleeve 4, after moving the lower baffle 6 to a suitable position, move the second positioning pin 61 so that the second positioning line passes through the second positioning hole 42 and is fixedly connected to the lower baffle 6. At this time, the lower baffle 6 and the lower insulation sleeve 4 are relatively positioned, which is convenient for the fixed installation of the lower baffle 6. Thus, it is convenient for steam to enter from the left side of the lower partition 6 and flow out from the right side of the lower partition 6. In actual operation, after the upper mold 1 and the lower mold 2 are closed, steam is injected into the lower steam inlet 43 through the pipeline, and the steam enters the lower steam cavity 41 from the left side of the lower partition 6 and flows out of the lower steam outlet 44 from the right side of the lower partition 6. The steam is sucked out from the lower steam outlet 44 through the pipeline, which is convenient for the lower insulation sleeve 4 to be heated and insulated, thereby facilitating the heating and insulation of the lower mold 2, and reducing the impact of temperature changes on the tire production process.

[0037] The implementation principle of a bias tire molding mold with a heat-insulating sleeve in the embodiment of the present application is as follows:

[0038] When the tire needs to be processed, after the upper mold 1 and the lower mold 2 are closed, steam is injected into the upper steam inlet 33 through the pipeline, and the steam is sucked out from the upper steam outlet 34 through the pipeline, so that the upper steam cavity 31 is filled with steam; steam is injected into the lower steam inlet 43 through the pipeline, and the steam is sucked out from the lower steam outlet 44 through the pipeline, so that the lower steam cavity 41 is filled with steam, which is convenient for the upper insulation sleeve 3 to heat and keep the upper mold 1 warm, and for the lower insulation sleeve 4 to heat and keep the lower mold 2 warm, which reduces the energy loss during the heating process, improves the heating rate, and improves the production efficiency of the tire.

When the upper mold 1 and the lower mold 2 are closed, the movement of the upper mold 1 can drive the movement of the first connecting rod 511, and the movement of the first connecting rod 511 can drive the movement of the connecting block 512, so that the connecting rod is embedded in the connecting groove 612, and the connecting groove 612 can limit the first connecting rod 511, thereby limiting the upper mold 1, so that the upper mold 1 and the lower mold 2 are relatively fixed, and the closing accuracy of the upper mold 1 and the lower mold 2 is further improved.

[0042] The implementation principle of a bias tire molding mold with a heat-insulating sleeve in the embodiment of the present application is as follows:
