A fixed structure of snow tire mold spike pin

摘要

The present invention relates to a spike pin of a vulcanizing mold for forming a spike pin hole in the PTN during snow tire manufacturing, and relates to a spike pin fixing structure of a mold for manufacturing a snow tire which prevents the detachment of the spike pin.;The spike pin fixing structure of the mold according to the present invention is a structure in which the joint portion of the spike pin insertion groove 10 and the spark pin 30 of the mold is screwed, so that the tire and spike pins are repeatedly pulled out when the tire is taken out after vulcanization. It is firmly fixed so that there is no deviation of the spikes.
