Tire mold movable type block machining tool

Abstract

The invention discloses a tire mold movable type block machining tool. The tire mold movable type block machining tool comprises a bottom plate and a movable type block, and is characterized in that threaded holes and a plurality of radial grooves are formed in the bottom plate in the circumferential direction and the radial direction, and the bottom plate is equally divided by the grooves; the movable type block is tightly attached to the bottom plate, a T-shaped block fixed above the grooves and used for clamping the movable type block is arranged on one circumferential side of the movable type block, and a first eccentric fastening screw cooperating with the T-shaped block and used for fixing the movable type block in the circumferential direction is arranged on the other circumferential side of the movable type block; and a positioning column used for fixing the movable type block in the radial direction is arranged on one radial side of the movable type block, and a second eccentric fastening screw cooperating with the positioning column and used for fixing the movable type block in the radial direction is arranged on the other radial side of the movable type block. Accordingto the tire mold movable type block machining tool, the problems that a traditional movable type block machining tool is troublesome to replace, suction force of a suction cup is not easy to control,and that only one movable type block is machined at a time can be solved, the machining efficiency of the movable type block is improved, and manpower is saved.

Description

technical field [0001] The invention relates to the technical field of tire molds, in particular to a tire mold movable type block processing tool. Background technique [0002] The movable type block is a part used to replace the characters on the bottom plate in the tire mold. It is fan-shaped. When the movable type block is processed, it needs to be fixed on the bottom plate and processed by a CNC machine. There are two traditional fixing methods: one is to process bolt holes on the bottom plate and fasten them with bolts from the back of the bottom plate, and each processing needs to be drilled for fastening and disassembly; the other is to use magnetic suction cups to fix. However, there are certain defects in the above two methods. The first fixing method is cumbersome to replace and requires a lot of manpower; the second fixing method is not easy to control the suction of the suction cup. The suction of the suction cup is large, and the chips will adhere to it. The su...
