Description

Technical Field

[0001] The utility model relates to the technical field of automobile molds, in particular to a batch processing device for circular needles of automobile molds. Background Art

[0002] There are many circular needles in automobile molds, but the circular needles are cylindrical in shape. During the CNC machining process, clamping and processing are difficult. Installing them into the mold for assembly processing requires processing time of large CNC machine tools, and the angles cannot be processed in place. If the commonly used vise is used for clamping and processing, the ejector pins will vibrate during the processing, and the processed surface will be rough and cannot meet the requirements, and mass production is impossible. If the ejector pins are clamped in a vise one by one for CNC machining, the efficiency is too low. Therefore, a batch processing device for circular needles in automobile molds is proposed.
