Description

Technical Field

[0001] This utility model relates to the field of mold adjustment technology, specifically an adjustable mold device for casting and molding non-ferrous metal alloys. Background Technology

[0002] Casting is a method of pouring molten metal into a casting cavity that conforms to the shape of the part, allowing it to cool and solidify to obtain the part or blank. The material being cast is often a metal that was originally solid but has been heated to a liquid state, while the mold material can be sand, metal, or even ceramic. In the casting process of non-ferrous metal alloys, the design and manufacture of the mold have a crucial impact on the quality of the final product and production efficiency.

[0003] Once the shape of a fixed mold is determined, it is difficult to change it quickly. When it is necessary to produce castings with different shapes, the entire mold must be replaced, which usually takes a lot of time. The increased mold changeover time directly reduces production efficiency and increases production costs.

[0004] To address these issues, we propose an adjustable mold device for casting non-ferrous metal alloys. Utility Model Content

A roller is fixedly connected to the bottom of the solution tank, and the roller is rotatably connected to the second sliding groove, so that the solution tank can drive the right mold closing unit above to move and adjust its position. The cooperation between the roller and the second sliding groove reduces friction and resistance during movement, and improves the stability and durability of the equipment.

The threaded connection between the motor and the connecting block allows for precise control of the movement distance and speed of the right mold-closing unit; the slide rod provides additional stability, preventing the right mold-closing unit from shifting or tilting during movement.

[0012] Preferably, a limit plate is fixedly connected to the right side of the mounting plate, which limits the maximum movement distance of the right mold closing unit and prevents equipment damage caused by excessive movement.

[0013] Preferably, the upper surface of the worktable is provided with a sliding groove and a through groove. A slider is slidably connected inside the sliding groove. The upper surface of the slider is fixedly connected to the support plate. The transport pipe is movably connected inside the through groove.

It also has the function of mold rotation, providing the necessary cooperation for the casting.

[0026] Example 2:

[0027] Based on Embodiment 1, the right mold-closing unit is equipped with a liquid injection assembly, which includes a distribution pipe 602, a transport pipe 601, and a solution tank 4. One end of the distribution pipe 602 is located inside each mold 708, and the other end is fixedly connected to the inside of the rotating shaft 706 and connected to the transport pipe 601, so as to evenly distribute the alloy liquid in the solution tank 4 into each mold 708. A valve is provided on the distribution pipe 602 to control the opening and closing of the distribution pipe 602, so as to achieve precise injection and flow control of the alloy liquid. One end of the transport pipe 601 is located inside the rotating shaft 706, and the other end of the transport pipe 601 is connected to the inside of the solution tank 4, connecting the solution tank 4 and the distribution pipe 602 to ensure smooth transmission of the alloy liquid. A mounting plate 2 is fixedly connected below the workbench 1. A sliding groove 304 is opened on the upper surface of the mounting plate 2. Rollers 401 are fixedly connected to the bottom of the solution tank 4 to facilitate the movement of the solution tank 4 and the right mold-closing unit on it. Roller 401 is tactilely connected to slide groove 304.

[0028] The drive unit includes a motor 301, a slide bar 302, a threaded rod 303, and a connecting block 305. Motor 301 is connected to the left side of the worktable 1 and is connected to the threaded rod 303 via a coupling, providing power to the threaded rod 303 and driving the movement of the solution tank 4 and its right mold-closing unit. The threaded rod 303 is connected to the front of the worktable 1, and the slide bar 302 is connected to the back of the worktable 1. The connecting block 305 is fixedly connected to both the front and back of the solution tank 4, and is threadedly connected to the threaded rod 303 and slidably connected to the slide bar 302. A limit plate 5 is fixedly connected to the right side of the mounting plate 2 to limit the maximum movement distance of the solution tank 4 and its right mold-closing unit, preventing damage to the equipment due to excessive movement.

[0029] The upper surface of the workbench 1 is provided with a sliding groove 101 and a through groove 102. A slider is slidably connected inside the sliding groove 101. A support plate 701 is fixedly connected to the upper surface of the slider. The transport pipe 601 is movably connected inside the through groove 102 to provide space for the transport pipe 601 and ensure the smoothness of the alloy liquid during the transmission process.

[0030] Working Principle: The shape of mold 708 is adjusted according to production requirements. Motor 703 is started, driving worm gear 704 to rotate. Worm gear 704 meshes with worm wheel 705, achieving smooth power transmission. Worm wheel 705 drives rotating shaft 706 via connecting shaft, which in turn drives cross 707 and mold 708 to rotate, enabling rapid mold changes and adapting to the production needs of castings with different shapes. Motor 301 drives threaded rod 303 to rotate, which, via connecting block 305, drives solution tank 4 and its right mold-closing unit to move under the guidance of slide rod 302 and threaded rod 303, achieving mold closing.

[0031] The molten alloy in solution tank 4 is then transferred to the inside of rotating shaft 706 via transport pipe 601, and then evenly distributed to each mold 708 via distribution pipe 602. The valve on distribution pipe 602 controls the injection and flow rate of the molten alloy. After the molten alloy cools and solidifies, motor 301 is restarted to drive the threaded rod to rotate, thus opening the mold.
