[0024] Reference Figures 1-4 The embodiment provides a heat preservation structure for providing a constant temperature environment for the vulcanization mold 11 at the position of the periphery of the vulcanization mold, which is matched with a vulcanization machine. Specifically, the heat preservation structure comprises a cylinder 13 enclosed at the position of the periphery of the vulcanization mold, and the lower end of the cylinder 13 is fixed by the clamping of the bolt protruding on the end plate 12 at the lower position of the vulcanization machine through the limiting portion 132 arranged on the outer peripheral wall surface thereof. The cylinder 13 and the end plate 12 of the vulcanization machine form a heat preservation chamber surrounding the vulcanization mold 11. Specifically, from the structural composition, the cylinder 13 is a sandwich structure, comprising a heat-resistant plastic steel layer close to the vulcanization mold 11, a heat preservation layer at the intermediate position and a heat insulation decorative layer at the outer side; from the overall appearance, the height of the cylinder 13 should be not less than 300 mm, and the thickness of the cylinder wall should be not less than 35 mm. Moreover, the cylinder wall of the cylinder 13 is provided with notches 131 for the steam hose to enter, and the notches 131 should be not less than two and arranged at intervals, and the cross-sectional diameter of a single notch 131 should be not greater than 1 / 5 of the height direction size of the cylinder 13 to ensure the heat preservation and heat insulation effect of the lateral wall surface of the cylinder 13.

[0025] From the constituent material of the cylinder 13, the heat preservation layer at the intermediate sandwich position is made of fibrous heat insulation material by pressing molding, and the fibrous heat insulation material can be one or a combination of rock wool, asbestos, slag wool or glass fiber. The fiber length of the fibrous heat insulation material is not less than 10 mm, and the thermal conductivity coefficient of the fibrous heat insulation material is not greater than 0.2 W / (m·k). The heat-resistant plastic steel layer and the heat insulation decorative layer molded together with the heat preservation layer have physical performance parameters respectively as follows: the effective thickness of the heat-resistant plastic steel layer is not less than 1.5 mm, and the heat insulation decorative layer is a color steel plate, and the effective thickness of the color steel plate is not less than 1 mm.

[0026] The working process of the heat preservation structure of the vulcanization mold 11 is as follows: the cylinder 13 corresponding to the outer dimension of the vulcanization mold 11 is taken, the relative position of the cylinder 13 and the vulcanization machine is fixed by clamping the limiting part 132 on the cylinder 13 with the bolt on the end plate 12 at the lower position of the vulcanization machine. The vulcanization machine is driven to make the end plate 12 at the upper and lower positions close to each other until the vulcanization mold 11 at the position of the upper end plate 12 and the vulcanization mold 11 at the position of the lower end plate 12 are combined. Since the cylinder 13 is fixed on the lower end plate 12, and the lower vulcanization mold 11 is arranged in the cylinder 13, when the vulcanization mold 11 is combined under the driving of the end plate 12, the end plate 12 on the vulcanization machine is clamped with the cylinder 13 to form a heat preservation chamber surrounding the vulcanization mold 11. The heat preservation sleeve ring is arranged around the vulcanization mold 11, the exposed surface of the vulcanization mold 11 is effectively isolated from the outside, the heat dissipation area is reduced, in the production of the heated vulcanization product, the heat loss can be effectively reduced, the vulcanization mold 11 used is less affected by the environment temperature, the heat preservation efficiency is improved, and the steam consumption is saved.
