A stable side supporting effect is provided for the motor through the right-angle frame, then the stability of the motor in the using process is guaranteed, a sliding adjustment space is provided through the sliding groove, then the sliding and guiding effects are conveniently provided for the sliding block in the longitudinal adjustment process, and the rapid and high-precision adjustment function is achieved.

This utility model discloses a tie rod structure for a dual-motor injection molding machine, including a tailstock and a headstock. The tailstock and headstock are fixed together by multiple tie rods. A middle frame is slidably connected to a lead screw. Two sets of drive assemblies are detachably mounted on the tailstock. Two lead screw assemblies are provided between the tailstock and the middle frame corresponding to the two sets of drive assemblies. The drive assemblies drive the lead screw assemblies to rotate, and the lead screw assemblies can extend and retract through rotation to drive the middle frame to slide on the tie rods. By combining a double-ended threaded lead screw assembly with a synchronous toothed belt drive, the output deviation of the dual motors is effectively eliminated, ensuring the precise sliding of the middle frame on the four high-strength tie rods and significantly reducing the risk of skewing.
