Detailed Description
The technical solution of the present invention will be described in detail with reference to the accompanying drawings.
In the description of the present application, it is to be understood that the terms "upper", "lower", "left", "right", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings.
In the description of the present application, it is to be understood that reference to the bottom of the nozzle is to the position opposite the inlet of the nozzle, i.e. to the rightmost side of the nozzle as viewed in fig. 2.
The specific embodiment is as follows:
the outer mold of the mold for molding the vulcanized tire shown in fig. 1 comprises a first outer mold 1, a second outer mold 2, an air inlet 3, an air outlet 4, an air guide part 5 and a connecting part 6, wherein the first outer mold 1 and the second outer mold 2 are both semicircular and provided with air chambers, one ends of the first outer mold 1 and the second outer mold 2 are connected through hinges, the air inlet 3 and the air outlet 4 are respectively arranged at one ends of the first outer mold 1 and the second outer mold 2 close to the hinge, and the other ends of the first outer mold 1 and the second outer mold 2 are connected through the connecting part 6. The connecting portion 6 comprises a first connecting plate 601 and a second connecting plate 602 which are respectively arranged at the ends of the first outer die 1 and the second outer die 2, at least one threaded hole 604 is respectively arranged on the first connecting plate 601 and the second connecting plate 602, and two threaded holes 604 are preferably respectively arranged on the first connecting plate 601 and the second connecting plate 602. The locking bolt 603 connects the first connecting plate 601 and the second connecting plate 602 through the threaded hole 604, and when the two are connected together, a circular outer mold which can be sleeved on the outer side walls of the upper mold and the lower mold is formed. Since the outer die is sleeved on the outer side wall of the die, the inner diameter R of the annular outer die is slightly larger than the outer diameters of the upper die and the lower die, but if the inner diameter R of the outer die exceeds the outer diameters of the upper die and the lower die too much, the gap formed between the outer die and the lower die will affect the heat conduction, so the inner diameter R of the outer die is preferably set to be 1mm to 2mm larger than the outer diameters of the upper die and the lower die, so that the outer die can be tightly sleeved on the outer portions of the upper die and the lower die under the action of the locking bolts 603 of. In addition, because the outer side walls of the upper die and the lower die need to be sleeved with the outer die, as shown in fig. 3, the axial height H of the outer die cannot exceed the sum of the heights of the upper die and the lower die, and the height H is only slightly lower than the sum of the heights of the upper die and the lower die by 3mm to 5 mm.
In order to provide the connection part 6 and to prevent heat loss of the outer molds, the first outer mold 1 and the second outer mold 2 are both configured as a 4-layer structure as shown in fig. 2, and from the outside to the inside are an outer plate 7 made of stainless steel, which plays a role of protecting and fixing the connection part 6, an insulation layer 8 made of rock wool, an inner plate 9 made of stainless steel, and an air chamber 10 disposed at the innermost layer and directly contacting the upper mold and the lower mold, respectively. The air guide part 5 is arranged to be used for connecting the air chambers of the first outer die 1 and the second outer die 2, the air guide part 5 comprises an air outlet nozzle 501 arranged at the end part, far away from the hinged end of the air chamber, of the first outer die 1 and an air inlet nozzle 502 arranged at the end part, far away from the hinged end of the air chamber, of the second outer die 2 and matched with the air outlet nozzle 501, a high-temperature-resistant sealing rubber gasket 503 with an air hole in the middle is arranged at the bottom of the air inlet nozzle 502, the air outlet nozzle 501 can be inserted into the air inlet nozzle 502, and the end part. Here, the air outlet nozzle 501 and the air inlet nozzle 502 serve to connect the air cells in the first outer die 1 and the second outer die 2, and if each is set to 1, the air outlet nozzle and the air inlet nozzle will affect the flow of the hot steam inside the two air cells, so it is preferable to set the air outlet nozzle 501 and the air inlet nozzle 502 to 2 respectively.
