Detailed Description

The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:

as shown in fig. 1 to 7, a solid tire mold mainly comprises an upper mold body 1 and a lower mold body 2 which are arranged in a vertically opposite manner, wherein an upper mold cavity is arranged in the upper mold body 1, and a lower mold cavity is arranged in the lower mold body 2. In order to prevent glue overflow, a glue overflow structure for discharging excessive glue in the upper and lower die cavities is arranged on the top surface of the lower die body 2, and the glue overflow structure is in the prior art and is not described herein.

A mold clamping and positioning structure for positioning the upper mold body 1 when moving downwards is arranged between the upper mold body 1 and the lower mold body 2. The concrete structure of compound die location structure includes reference column 8, and the lower extreme of reference column sets up to the tapering section that the diameter reduces gradually downwards, is provided with reference column mounting hole 1a in last die body 1, and the upper end of reference column 8 passes through the bolt fastening in reference column mounting hole 1a, is provided with the reference column insertion hole 2a that corresponds with reference column mounting hole 1a in lower die body 2, is provided with the reference column guide ring 9 of being convenient for when the reference column inserts in the upper end of reference column insertion hole 2a simultaneously, and the internal diameter of reference column guide ring 9 is less than the internal diameter of reference column insertion hole 2 a.
