Embodiment

[0028] Precision casting: cast tire molds to produce unsplit quincunx-shaped aluminum tread rings;

[0029] Rough turning: the size of the back of the rough turning pattern ring of the tire mold after the above precision casting;

[0030] Splitting: cutting the pattern ring line of the tire mold after the rough car into a single block;

[0031] Fine milling on the upper and lower sides: Place the single pattern block of the split tire mold above on the upper and lower tire molds, and align and clamp it based on the inner diameter of the finely cast pattern block and the end face of the cavity. Finish milling on the top and bottom of the pattern block, and process the process groove of the pattern block;

[0032] Fine milling split surface: put the above-mentioned fine milled upper and lower single pattern blocks on the milling split surface tire, the process grooves processed in the above sequence, the top diameter of the pattern block and the center of the finely cast patter...

Abstract

The invention relates to processing technology of an aluminum pattern block for a tire mold. The processing technology comprises finish casting, rough turning, valving, upper and lower side finish milling, valving surface finish milling, finish turning and pattern modifying. The mold cavity of a casting part is taken as the overall dimension of a reference processing pattern block and the overalldimension is taken as the inner surface of a finish reference processing mold cavity, so that the gradient of the casting part is minimized, the pattern modifying workload of a bench worker is lowered greatly and the change of a pattern geometry is reduced. Moreover, damage to the finish casting inner surface is reduced while the pattern modifying workload is lowered and the formation of a shrinkage cavity under the shell of the casting part is avoided, so that the processing quality of the pattern block is enhanced and production efficiency is improved; and the technical problems of high casting gradient and pattern modifying workload instability which are not solved by technical personnel in the field are solved.

Description

technical field [0001] The invention relates to a processing technology of a pattern block, in particular to a processing technology of an aluminum pattern block of a tire mold. Background technique [0002] The pattern in the tire is not only the decisive factor for the beautiful appearance of the tire, but also is more related to whether the traction, braking, turning, water drainage and noise performance of the tire can be fully utilized. It is mainly composed of pattern grooves, pattern blocks and pitches. [0003] In the prior art, the processing technology of the tire mold aluminum pattern block consists of the following steps: [0004] 1. Precision casting: Casting an unsplit aluminum pattern ring; [0005] 2. Car: the back size of the rough and fine car pattern circle; [0006] 3. Splitting: cutting the pattern ring wire into a single piece; [0007] 4. Milling: rough and fine milling of the split face of the pattern block; [0008] 5. Fitter: Drill air holes an...
