Abstract
The invention discloses a one-time vulcanizing mold for a rubber belt track. The mold comprises a mold base, a heating plate, an inner mold, an outer mold, an outer mold rack, a central shaft and a conical plunger, wherein the central shaft is arranged on the mold base in the center of the inner mold, and the central shaft is connected with a driving device which drives the central shaft to move up and down; the conical plunger is provided with a central hole, and a clamping hole, which corresponds to connecting blocks, is formed in the side wall of the conical plunger; the conical plunger is arranged on the central shaft in a sleeving manner after the inner mold and the outer mold are closed; a limiting component is arranged on the upper part of the central shaft; the driving device drives the conical plunger to move downwards along the interior of the inner mold so as to apply pressure to the inner and outer molds by virtue of the central shaft and the limiting component; and discharging holes communicated with vulcanizing cavities are formed in the connecting blocks. When the vulcanizing mold is vulcanized, rubber can well flow into the vulcanizing cavity, the vulcanizing cavity is easily filled with the rubber, and perfect tooth punching is guaranteed. Therefore, the yield of the rubber belt track is increased.
