Abstract

This utility model discloses a fixture for fixing and inspecting polymer molds using laser technology. It includes an inspection table with a gantry frame fixedly connected to its bottom. The gantry frame has a lifting structure, and a rotating frame is located above the inspection table. Each rotating frame has a sliding groove on one opposite side, and a sliding rod is fixedly connected to each sliding groove. Two clamping plates are slidably connected to the two sliding rods, and rubber pads are fixedly connected to the opposite sides of the two clamping plates. This utility model utilizes a second servo motor, a worm gear, and a worm wheel. The second servo motor drives the worm gear to rotate via a second rotating shaft, and the worm gear drives a corresponding first rotating shaft to rotate. The first rotating shaft, through the rotating frame, causes the fixed double-sided mold to flip, eliminating the need for operators to disassemble the fixed double-sided mold. After flipping, it can be re-fixed, making operation convenient and improving inspection efficiency.
