[0040] In this embodiment, a heating structure for a vulcanizing machine die of the present utility model is given. By placing the product to be vulcanized in the middle template 2, then the upper die assembly 3 seals the middle template 2, and the heating mechanism 4 heats the middle template 2, so that the product in the middle template 2 is vulcanized. And through the heating mechanism 4, the heating wires 47 can be quickly replaced, thus avoiding affecting the processing efficiency of the product.

[0041] Furthermore, as Figures 2 to 3 shown, the lower template 1 in the preferred embodiment of the present utility model further includes a placement groove 11 opened on the upper surface of the lower template 1, and the middle template 2 is detachably disposed in the placement groove 11; a sealing groove 12 opened on the left side of the lower template 1, and the sealing plate 41 is detachably disposed inside the sealing groove 12; a heating groove 13 opened inside the sealing groove 12; and a support member 14 disposed inside the heating groove 13.

[0042] Even further, the support member 14 includes a support block 141 disposed inside the heating groove 13; a plurality of support grooves 142 evenly distributed and opened on the upper surface of the support block 141 and used for supporting the heating wires 47.

[0043] Even further, the inner side of the sealing groove 12 and the outer side of the sealing plate 41 are in interference fit, so as to ensure that the sealing plate 41 will not fall off from the sealing groove 12 during use.

[0044] In this embodiment, multiple preferred embodiments of the lower template 1 are given. Through the sealing groove 12 and the heating groove 13, the heating mechanism 4 can be located inside the lower template 1, so that the heating mechanism 4 can better heat the lower template 1 and the middle template 2. And through the support member 14, the heating wires 47 can be supported, avoiding one end of the heating wires 47 being always suspended, resulting in a short service life of the heating wires 47.

[0045] Furthermore, as Figure 4 shown, in the preferred embodiment of the present utility model, the upper die assembly 3 includes at least two guide posts 31, which are evenly distributed on the upper surface of the lower template 1; an upper template 32, which is slidably arranged outside at least two guide posts 31.

[0046] In this embodiment, multiple preferred embodiments of the upper die assembly 3 are given. Through the upper template 32, the middle template 2 can be sealed, so that the products in the middle template 2 can be better vulcanized. And through the guide posts 31, the stability of the upper template 32 when sealing the middle template 2 is ensured.

[0047] Furthermore, as Figure 5 shown, the heating mechanism 4 in the preferred embodiment of the present utility model further includes two support sleeves 43, which are symmetrically arranged on the upper surface of the mounting plate 42; two lead screws 44, which are respectively rotatably arranged inside the two support sleeves 43; two clamping plates 45, which are respectively rotatably arranged on the lower end surfaces of the two lead screws 44; two conductive blocks 46, which are respectively arranged between the lower parts of the two clamping plates 45 and the mounting plate 42, and heating wires 47 are respectively arranged between the right sides of the two conductive blocks 46.

[0048] Furthermore, the mounting plate 42 is a metal mounting plate, and the mounting plate 42 is electrically connected to the vulcanizing machine; a handle is arranged on the left side of the sealing plate 41.

[0049] Furthermore, both of the two conductive blocks 46 are electrically connected to the heating wire 47, and the two conductive blocks 46 are respectively located inside the two support sleeves 43; the heating wire 47 is located between the inside of a plurality of support grooves 142.

[0050] In this embodiment, multiple preferred embodiments of the heating mechanism 4 are given. Through the heating wire 47, the lower template 1 and the middle template 2 can be heated, so that the products in the middle template 2 can be vulcanized. When the heating wire 47 is damaged, the sealing plate 41 is pulled out from the sealing groove 12 through the handle, and then the lead screw 44 is rotated. The lead screw 44 will drive the clamping plate 45 to move upward, so that the heating wire 47 can be detached from the mounting plate 42. Then a new heating wire 47 is placed on the mounting plate 42, and the lead screw 44 is rotated in the reverse direction. The lead screw 44 drives the clamping plate 45 to clamp the conductive block 46, so that the heating wire 47 can be quickly replaced.
