Tire mold casting process

Yantai Wonray Rubber Tyre Co.,Ltd | Updated: Oct 27, 2017


Tire mold types are active mold, from the pattern circle, mold sets, the upper and lower side panels, active mold to distinguish the cone-oriented active mold and oblique plane-oriented active mold. There are two halves of mold, by the mold, the mold two pieces. The following example of a live mold to briefly describe his processing technology: according to the tire mold casting or forging rough, Mould on Tires and then roughing and heat treatment. Tire mold blank to complete the annealing process to eliminate the internal stress, annealing should be flat, to avoid deformation is too large; according to the drawings to lift the hole, and then press the semi-fine car drawings will be the outer diameter and height processing in place, Program car pattern lap cavity, Mould on Tires car finished with semi-fine model test; with a good tire mold pattern electrode pattern pattern with EDM processing, with a model test; the pattern ring according to the requirements of manufacturers are divided into several copies , Respectively, Mould on Tires to draw the marked line, into the tooling back waist and tapping; tapping in accordance with the order of 8, the alignment of the cutting line; cut the block according to the requirements of the drawings to light, Clean the edge, clear the root, playing the exhaust hole; on the block cavity cavity evenly sandblasting, the same color; the pattern ring, mold sets, Mould on Tires the upper and lower side plate assembly, complete tire mold.

The mold ring in the tire mold can be interchangeably exchanged without having to replace the entire mold, thereby saving the production and input cost of the mold; Mould on Tires by providing an exhaust groove between the pattern loop and the protective sleeve, So that the tire in the vulcanization has a good exhaust performance, and then just outside the general vacuum equipment can be achieved vacuum tire curing, Mould on Tires the tire quality has been greatly improved.

Tire mold operation tips

1, according to the tire mold casting or forging rough, and then roughing and heat treatment. Tire mold blank for complete annealing, to eliminate internal stress, annealing should be flat, to avoid deformation is too large;

2, according to the drawings to lift the hole, Mould on Tires and then press the semi-fine car drawings will be the diameter of the ring and the height of processing in place, with semi-precision car program car lap cavity, car finished with semi-fine model test;

3, with a good processing of the tire mold pattern electrode pattern pattern processing, with a model test;

4, the pattern according to the requirements of manufacturers are divided into several copies, respectively, draw the marked line, Mould on Tires into the tooling back waist and tapping;

5, according to the same part of the process of 8, Mould on Tires at the crossed line at the cut;

6, the cut a good block according to the drawings required to light the pattern, clear angle, clear roots, playing the exhaust;

7, the block block cavity even within the sandblasting, Mould on Tires the same color requirements;

8, the pattern ring, mold sets, the upper and lower side board assembly, complete tire mold.
