The tire mold mainly refers to the automobile tire, along with the unceasing progress of the society, the automobile industry is in full swing development, the automobile unceasing demand also promoted the automobile related industry development, like washes the car, the automobile mold, the tire, the automobile fitting and so on, Mould on Tires these related professions in the Automobile Industry Foundation, all developed very well. Today is mainly about the tire mold related knowledge.
Tire mold types have a lively mold, from the pattern circle, mold sets, the upper and lower side of the plate, the active mold to distinguish the cone-oriented mold and oblique plane-oriented mold. Mould on Tires There are two halves of the mold, from the upper die, the lower mold two pieces. The following is a brief description of his processing technology: according to the tire mold drawing casting or forging blanks, and then rough cars and heat treatment. Complete annealing treatment of tire die Blanks, elimination of internal stress, annealing should be put flat, Mould on Tires to avoid deformation too large; according to the drawings to play the hoisting hole, and then according to the semi-precision car drawings will be the outside diameter and height of the pattern of processing, with half a car program car pattern circle cavity, car finished with a semi-precision vehicle model With the processing of the tire mold pattern electrode to the pattern circle with EDM molding, with the model inspection, the pattern circle according to the requirements of manufacturers are divided into several parts, respectively, draw the marking line, Mould on Tires put into the fixture back waist hole and tapping; According to the equal parts of the process 8, align the cut To cut the pattern in accordance with the drawing requirements of the pattern to play light, clear angle, Qinggen, hit the exhaust hole, the pattern block cavity evenly sprayed sand, the color uniformity, the pattern ring, die sleeve, the upper and lower side plate combined assembly, complete the tire mold.
Tire Mold Processing Technology
Taking the active mould as an example
1: According to the tire mold drawing casting or forging blanks, and then rough cars and heat treatment. The tire die blank is completely annealed, the internal stress is eliminated, Mould on Tires the annealing should be flat and the deformation is avoided.
2: According to the drawings to play the hoisting hole, and then according to the half precision car drawing circle of the outside diameter and height processing in place, Mould on Tires with a half fine lathe program car pattern circle cavity, car finished with a half fine car model test.
3: With the processing of a good tire mold pattern electrode to shape the pattern of electric spark processing, with a model test.
4: The pattern circle according to the requirements are divided into several parts, respectively, Mould on Tires draw the Mark Line, put into the fixture back waist hole and tapping.
5: According to the working procedure 8 cent of the equal parts, at the line cut.
6: Cut a good pattern of the pieces according to the drawing requirements of the pattern to play light, clear angle, Qinggen, playing exhaust holes.
7: On the pattern block cavity evenly spraying sand, requirements color 1.
8: The pattern circle, the mold sleeve, Mould on Tires the upper and lower side plate are assembled to complete the tire mold.
