[0002] like Figure 7 As shown, the tread block is the core component of the tire mold, and its processing quality directly affects the tire's appearance and quality. Existing tread blocks are typically made of cast aluminum, and usually have internal holes at both ends. The symmetry and positional accuracy of its cavity curves are key aspects that need to be ensured during processing.

[0003] Specifically, the end face reference surface machining of cast aluminum patterned blocks is the first or second (after rough machining) finishing process in the entire patterned block machining process. By machining the end face of the cast aluminum patterned block (usually the back or bottom surface of the patterned block) into a high-precision plane, it serves as the process reference for all subsequent machining processes (such as milling, drilling, finishing, etc.). Therefore, the end face reference surface of cast aluminum patterned blocks has extremely high dimensional accuracy and geometric tolerance requirements.

[0004] Currently, the end face reference surface of cast aluminum patterned blocks is usually roughed using a vertical machining center or a large milling machine. Then, a three-jaw chuck with soft jaws, special fixtures, or pads and pressure plates on the worktable is used to align and initially fix the cast aluminum patterned blocks. This process requires a lot of manual operation, and a lot of time is spent on positioning and alignment. It is difficult to effectively guarantee the machining accuracy and quality. Furthermore, a lot of time needs to be spent on correction in subsequent processes, which seriously affects production efficiency.
