Manufacturing method of tire mould


1. After the tire model is evenly coated with release agent, blow dry. The tire model treated by inner tube mold is surrounded by steel plate, and the steel plate is also treated with release agent.

2. The silica gel and the curing agent are stirred evenly. The appearance of the silica gel of the mold is a flowing liquid, component A is silica gel, and component B is the curing agent. For example: take 100g of silica gel and add 2G of curing agent (Note: silica gel and curing agent must be stirred evenly. If they are not stirred evenly, one piece of the mold will be cured, and one piece will not be cured. The uneven drying and curing of silica gel will affect the service life of silica gel mold and the number of mold turnover, and even cause the mold scrap.

3. Vacuumizing and exhausting foam treatment: after the silica gel and curing agent are evenly stirred, the vacuumizing and exhausting foam link should be carried out. The vacuumizing time should not be too long. Under normal circumstances, it should not be more than 10 minutes. The vacuumizing time is too long. Silica gel solidifies immediately, resulting in cross-linking reaction, making silica gel become one piece by one, unable to be brushed or poured, which wastes silica gel, so silica gel can only be used Pour it into the garbage can and take the silica gel again 3. Pour the prepared glue slowly along a fixed pouring point, and shake it from time to time to remove the air inside.

4. After the glue is cured completely in 120 minutes, 1000g of gypsum powder is mixed with water and then injected into the wooden frame until it is full (the wooden frame shall be divided into two parts by plastic sheet to facilitate formwork removal).

5. After 20 minutes, remove the wood strip, and the mold is finished.


1. The dosage of curing agent shall be determined according to the temperature, and it will decrease when the temperature is high. If the curing agent is used too much, the mold will become hard and brittle; if the curing agent is used too little, the operation time will be prolonged.

2. In order to prevent the change of physical properties of silica gel, it is recommended not to add silicone oil.

3. In order to achieve the use effect of your mold, please store the mold for at least 24 hours before use The tire mold is used for vulcanizing all kinds of tire molds.
