Processing Technology of White Font on Side Plate of Tire Mold

Abstract

The invention belongs to the technical field of tire molds of automobiles and discloses a machining process for a white typeface of a side plate of a tire mold. The process avoids the problem that the machining precision is affected, the dimension is of frequent out-of-tolerance, the machining difficulty is increased and the machining time is shortened as deflection is generated by mounting an elongating plate to a machining electrode which is oversized to lead to inability of accurately locating by using a reference small electrode to adjust the tilt angle of a chuck and mounting a sample plate on a curved surface of a cavity of the side plate; meanwhile, the problem that the machining precision is decreased due to precision loss caused by use of a machine tool for a long time can be avoided. The machining process provided by the invention is simple and feasible in process and convenient to operate. By adopting EDM linked machining, the contour of the side plate is not eroded, so that the machining precision, the locating accuracy and the shaping dimension accuracy are improved, out-of-tolerance is avoided, and the machining time is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of automobile tire molds, in particular to a process for processing white fonts on side plates of tire molds. Background technique [0002] The production of tires is inseparable from molds, which have a high degree of specialization, commercialization and production concentration. The mold structure ranges from simple to complex, and the mold materials range from cast iron to cast steel, cast aluminum and alloy cast steel. The mold processing technology also varies from Simple manual, EDM to applique processing. With the rapid development of the automobile industry, tire companies have higher and higher requirements on the precision, quality, life and delivery time of molds, forcing many mold manufacturers to make a fuss about the precision and quality of molds in order to meet their own needs. , to ensure that the tires produced by customer tire companies are beautiful, accurate and durable. However, the...

Problems solved by technology

In order to improve the performance of the tire pattern and the beauty of the white font pattern or trademark, many tire manufacturers require the side plate steel sheet of the tire mold to have a complex structure or a three-dimensional structure, and at the same time require the white font pattern or trademark to be processed accurately and with high precision. It brings certain difficulties to the processing of tire molds

[0004] The current processing method generally uses electric machining to process the white font pattern or trademark on the side panel, but because the white font is a 3D large character, the depth on the side panel mold is relatively deep, and the electrical machining method is usually easy to corrode the side panel surface, and Unable to accurately locate during repeated processing, which affects the processing accuracy, and the size is often out of tolerance, which increases the processing difficulty and processing time

Therefore, the processing technology of this kind of tire mold is not ideal in the actual production process. The burden on it is poor in practicability
