Description

Technical Field

[0001] This utility model relates to the field of die casting mold technology, specifically a high-efficiency zinc-magnesium alloy die casting mold. Background Technology

[0002] Die casting is a metal casting process that involves filling a mold cavity with molten alloy under high pressure and high speed, and then cooling it under high pressure to form the final product. It is one of the most widely used and fastest-growing metal hot forming processes in the casting industry. With the continuous improvement of die casting equipment and technology, the application scope of die casting products will continue to expand on the existing basis.

[0003] Chinese Patent Publication No. CN222359241U discloses "A High-Efficiency Zinc Alloy Die-Casting Mold," comprising: a support platform; horizontal telescopic rods fixedly installed at both ends of the support platform; an mounting sleeve fixedly connected to the outer surface of one end of each horizontal telescopic rod; a support base fixedly connected above the mounting sleeve; a vertical telescopic rod fixedly connected above the support base; a connecting sleeve fixedly connected to one end of the vertical telescopic rod; a support rod fixedly connected to one side of the connecting sleeve; an mounting block fixedly connected to one side of the support rod; a connecting block movably connected to one side of the mounting block; a vertical rod fixedly installed to one side of the connecting block; and a positioning pad movably connected to the upper part of the lower mold. This novel design, by adjusting the positioning pad, allows for adjustment based on the size and shape of the casting, facilitating increased use of the die-casting mold, improving casting processing efficiency, and enhancing the practicality of the die-casting mold.

[0004] While existing technologies can be adjusted according to the size and shape of the casting, the castings still need to be manually removed from the mold during use. This is not only inefficient but also increases labor intensity. Manual demolding requires operators to directly contact the high-temperature mold and castings, posing safety risks such as burns. Furthermore, different die-casting processes have different requirements for the mold's movement distance, making it impossible to control the moving mold's movement distance and speed during the die-casting process, thus failing to ensure the dimensional accuracy and surface quality of the castings. Utility Model Content

[0005] The purpose of this utility model is to provide a high-efficiency zinc-magnesium alloy die-casting mold to solve the problems in the background technology where castings need to be manually removed from the mold during use, which is not only inefficient but also increases labor intensity. Manual demolding requires operators to directly contact the high-temperature mold and castings, posing safety risks such as burns. At the same time, different die-casting processes have different requirements for the mold's moving distance, making it impossible to control the moving distance and speed of the moving mold during the die-casting process, and thus failing to ensure the dimensional accuracy and surface quality of the castings.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency zinc-magnesium alloy die-casting mold, including a worktable and a small threaded rod, wherein a die-casting assembly is provided on the top of the worktable and a lifting assembly is provided on the bottom of the worktable; The die-casting assembly includes a fixed block, and a limiting block is fixedly connected to one side of the outer surface of the fixed block. A movable block is slidably embedded inside the limiting block, and a slot is fixedly connected to the top of the outer surface of the movable block. A sphere is rotatably embedded inside the slot, and an upper mold is fixedly connected to the bottom of the outer surface of the movable block. The lifting assembly includes a fixed box, and a connecting plate is provided inside the fixed box. Multiple limiting rods are rotatably embedded inside the connecting plate. Multiple limiting rods are fixedly connected to the top of the outer surface of the connecting plate, and a limiting plate is fixedly connected to the top of the outer surface of each of the multiple limiting rods. Multiple small threaded rods are rotatably embedded inside the limiting plate. Threaded blocks are threaded on the outer surface of each of the multiple small threaded rods, and a lifting column is fixedly connected to the top of the outer surface of each of the multiple threaded blocks.

[0007] Preferably, an eccentric rod is rotatably embedded inside the fixed block, and multiple eccentric plates are fixedly connected to the outer surface of the eccentric rod. A connecting column is rotatably embedded inside each of the multiple eccentric plates, and a connecting tube is rotatably sleeved on the outer surface of each of the multiple connecting columns. A large threaded rod is embedded in the internal thread of the connecting tube, and the large threaded rod is fixedly connected to the outer surface of the sphere.

[0008] Preferably, an output rod is rotatably embedded inside the fixed box, and an output gear is fixedly connected to the outer surface of the output rod. A connecting rod is rotatably embedded inside the fixed box, and a connecting gear is fixedly connected to the outer surface of the connecting rod. The outer surface of the connecting gear meshes with the output gear. A connecting helical gear is fixedly connected to the outer surface of the connecting rod.

[0009] Preferably, a transmission rod is rotatably embedded inside the connecting disc, and a power helical gear is fixedly connected to the top of the outer surface of the transmission rod. The outer surface of the power helical gear meshes with the connecting helical gear, and the power gear is fixedly connected to the outer surface of the transmission rod.

[0010] Preferably, the connecting disc has multiple linkage rods rotatably embedded inside, and the outer surfaces of the multiple linkage rods are fixedly connected to transmission gears. The outer surfaces of the multiple transmission gears are all meshed with the power gears, and one side of the outer surface of the multiple linkage rods is fixedly connected to a small threaded rod.

[0011] Preferably, a first motor plate is fixedly connected to one side of the outer surface of the fixing block, and a first motor is provided on the top of the outer surface of the first motor plate. The output shaft of the first motor is fixedly connected to the eccentric rod. A second motor plate is fixedly connected to one side of the outer surface of the fixing box, and a second motor is provided on the top of the outer surface of the second motor plate. The output shaft of the second motor is fixedly connected to the output rod.

[0012] Preferably, the workbench is provided with a lower mold inside, and a plurality of lifting columns are slidably embedded inside the lower mold, and a plurality of threaded blocks are slidably sleeved on the outer surface of the limiting rod.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are: When die casting is required, the first motor on the top of the first motor plate is turned on. The output shaft of the first motor is fixedly connected to the eccentric rod. The first motor drives the eccentric rod to rotate, which in turn drives the eccentric plate to rotate. The eccentric plate drives the connecting pipe to rotate through the connecting column. The connecting pipe is connected to the ball-shaped moving block through a large threaded rod. The first motor drives the moving block to reciprocate up and down inside the limiting block. When it is necessary to adjust the movement range of the moving block, the large threaded rod is rotated, thereby threading the large threaded rod into the interior of the connecting pipe, thus adjusting the length of the large threaded rod and changing the movement range of the moving block. Through the above technical solution, the rotational motion is converted into linear reciprocating motion, which can accurately control the moving distance and speed of the upper mold during the die casting process, ensuring the dimensional accuracy and surface quality of the casting. Moreover, by controlling the reciprocating movement distance of the upper mold, the production needs of castings of different sizes can be met.

[0014] Secondly, after the casting is completed, the second motor on the top of the second motor plate is turned on. The output shaft of the second motor is fixedly connected to the output rod. The second motor drives the output rod to rotate, which in turn drives the output gear to rotate. The output gear then drives the geared connecting gear to rotate, which in turn drives the connecting helical gear to rotate via the connecting rod. The connecting helical gear then drives the geared power helical gear to rotate, which in turn drives the power gear to rotate via the transmission rod. The power gear then drives multiple transmission gears to rotate, which in turn drives the linkage rod to rotate. The linkage rod then drives the small threaded rod to rotate, which in turn drives the threaded block to move. The movement of the threaded block then drives the lifting column to move up and down. The lifting column has a hollow internal structure. The lifting column ejects the casting from the lower mold. This technical solution reduces the time spent manually removing parts, thereby improving the overall efficiency of the production line. Furthermore, the multiple lifting columns maintain the shape and size stability of the casting, reducing deformation or damage caused by improper demolding. Attached Figure Description
