This utility model discloses an aluminum profile production mold with a buffer structure, relating to the field of aluminum profile production technology. The utility model includes a worktable, on which a buffer mechanism and a demolding mechanism are provided. The buffer mechanism includes a connecting plate disposed at the bottom of the worktable. Two fixing blocks are fixedly connected to the left side of the connecting plate, and a sliding rod is fixedly connected between the two fixing blocks. Two sliders are slidably connected to the sliding rod, and spring sheets are fixedly connected to the sides of the two sliders that are furthest from each other. This utility model, by setting up a buffer mechanism, solves the problem that existing aluminum profile production molds are not convenient for buffering the force when merging two molds. The large impact force during merging can damage the mold and its cavity, thus affecting the mold's accuracy and causing deviations in the shape and size of the formed aluminum profile.

The invention discloses a horizontal continuous casting crystallization cavity low-oxygen copper liquid bubble eliminating method and device, and relates to the technical field of low-oxygen copper liquid continuous casting crystallization, a continuous casting machine shell and a bubble eliminating cavity are included, a continuous casting crystallization mechanism is arranged in the continuous casting machine shell, and a stirring mechanism is arranged in the bubble eliminating cavity. The stirring mechanism comprises a first motor arranged in the bubble eliminating cavity, a sliding groove is formed in the first motor, a sliding block is slidably connected to the interior of the sliding groove, a threaded rod is arranged at the output end of the first motor, a threaded cylinder is in threaded connection to the exterior of the threaded rod, and an air suction cylinder is fixedly connected to the interior of the bubble eliminating cavity. The thorn-shaped stirring fan can stir copper liquid in the bubble eliminating cavity at different heights, so that bubbles in the copper liquid are punctured and eliminated, dead angles are few when the bubbles are eliminated, a vacuum environment is formed in the bubble eliminating cavity, some missing bubbles are eliminated again, and the bubbles can be effectively prevented from being generated again in the copper liquid.
