Automobile tire mold processing technology

Take the active mold as an example for automobile molds

1: Cast or forge the blank according to the tire mold diagram, and then rough the blank and heat treatment. Car mold tire mold blanks are fully annealed to eliminate internal stress. They should be laid flat during annealing to avoid excessive deformation.

2: Drill the hoisting holes according to the drawing, and then process the outer diameter and height of the pattern ring according to the semi-finished turning drawing. Use the semi-finished turning program to turn the inner cavity of the pattern ring, and inspect the semi-finished turning model after turning.

3: Use the processed tire mold pattern electrode to shape the inner pattern of the pattern ring by EDM, and use the template for inspection.

4: Divide the pattern ring into several parts according to the manufacturer's requirements, draw the marking lines respectively, and put them in the tooling to punch the back waist hole and tap the thread.

5: According to the equal parts divided in process 8, align and cut at the scribe line.

6: The cut pattern blocks are polished, corners, roots, and vent holes are drilled according to the requirements of the drawings.

7: Sand blasting uniformly inside the pattern block cavity, and the color is required to be consistent.

8: Combine the pattern ring, mold sleeve, upper and lower side plates to complete the tire mold.
