A two-color injection mold for a rotary encoder backshell

Abstract

This utility model discloses a two-color injection mold for the rear shell of a rotary encoder, relating to the field of injection mold technology. It includes a worktable, with support columns fixedly connected to the four corners of the upper end of the worktable. A top frame is fixedly connected to the upper end of each support column, and support legs are fixedly connected to the four corners of the lower end of each support column. A first motor is fixedly installed at the center of the lower end of the worktable. The output end of the first motor passes through the lower end of the worktable and is fixedly connected to a turntable. The lower end of the turntable is rotatably connected to the upper end of the worktable. A first moving mold base and a second moving mold base, symmetrically distributed, are fixedly connected to the upper end of the turntable. This utility model achieves precise positioning of the turntable rotation through the cooperation of an arc-shaped positioning groove, an arc-shaped positioning block, and a first contact sensor. The cooperation of the push block and the second contact sensor further improves the precise positioning of the turntable rotation, ensuring the accuracy of moving mold switching, thereby guaranteeing the accuracy of subsequent mold closing and improving product quality.
