Description

Technical Field

[0001] This utility model relates to the field of tire production equipment, specifically to a blowing and drying device for the upper mold cavity of a vulcanizing chamber. Background Technology

[0002] Currently, with the rapid development of China's automotive industry, the demand for tires is increasing. Tire production generally involves the following steps: raw material preparation – rubber refining and compounding – tread and carcass manufacturing – semi-finished product production – molding – vulcanization – quality inspection and packaging.

[0003] After assembling semi-finished products such as the tread, carcass, and cord fabric into a green tire (an uncured tire, also called a tire blank) on a forming machine, the formed green tire needs to be placed in a vulcanizing machine and vulcanized in a mold under appropriate time and conditions. Vulcanization is one of the key steps in tire production. It enables the rubber to bond tightly to the carcass, forming the tire and improving its strength and wear resistance.

[0004] The green tire is placed in the vulcanizing chamber of the vulcanizing machine for vulcanization. During vulcanization, moisture in the green tire gradually separates, and water vapor condenses on the inner wall of the vulcanizing chamber, forming water droplets. After vulcanization, the upper vulcanizing chamber mold (i.e., the upper mold cavity) is lifted by a gantry crane, and the tire is moved away by a robotic arm. Workers then need to use handheld equipment to dry the moisture on the inner walls of the upper and lower vulcanizing chamber molds to prevent affecting the vulcanization of the next green tire. During the drying process of the upper vulcanizing chamber mold, workers need to stand directly below it, holding tools and looking upwards; this is not only extremely arduous and inefficient, but also carries the safety risk of the upper vulcanizing chamber mold accidentally falling and injuring workers.
