Description

Technical Field

[0001] This utility model relates to the technical field of magnesium alloy die casting equipment, specifically a magnesium alloy die casting device with a quick-change mold-locking structure. Background Technology

[0002] Magnesium alloys are alloys composed of magnesium as a base and other elements added. Their characteristics include: low density, high strength, high elastic modulus, good heat dissipation, good vibration damping, greater impact load capacity than aluminum alloys, and good resistance to corrosion from organic matter and alkalis. The main alloying elements include aluminum, zinc, manganese, cerium, thorium, and small amounts of zirconium or cadmium. Magnesium-aluminum alloys are the most widely used, followed by magnesium-manganese alloys and magnesium-zinc-zirconium alloys. They are mainly used in aerospace, transportation, chemical, and rocket industries. Magnesium alloy forming largely relies on die casting, where molten magnesium alloy is pressed into a mold cavity under high pressure, and high-precision castings are obtained after cooling. However, traditional magnesium alloy die-casting equipment uses multiple sets of bolts to fix the mold, which requires manual calibration and positioning during installation. When changing the mold, all bolts must be removed first, and then the mold center must be manually calibrated with a dial indicator to match the injection center of the die-casting machine, resulting in a long mold change time.

A magnesium alloy die casting device with a quick-change locking structure includes: a magnesium alloy die casting machine body 1. The magnesium alloy die casting machine body 1 has a fixed mold mounting plate 2 and a moving mold mounting plate 5 inside. A fixed mold 3 and two sets of locking mechanisms 4 are arranged on the side of the fixed mold mounting plate 2 near the moving mold mounting plate 5. A moving mold 6 and two sets of locking mechanisms 7 are arranged on the side of the moving mold mounting plate 5 near the fixed mold mounting plate 2. The locking mechanisms 7 have the same structure as the locking mechanisms 4. The installation method of the moving mold mounting plate 5 and the moving mold 6 is the same as that of the fixed mold mounting plate 2. Similar to the installation method of the fixed mold 3, the locking mechanism 4 includes a positioning plate 41, a sliding rod 42, a limiting block 43, a connecting plate 44, and a spring 45. The positioning plate 41 is fixedly connected to the front of the fixed mold mounting plate 2. The sliding rod 42 is slidably connected to the positioning plate 41, and there are two sets of sliding rods 42. The limiting block 43 is fixedly connected to the end of the sliding rod 42 near the fixed mold 3. The connecting plate 44 is fixedly connected to the end of the two sets of sliding rods 42 away from the limiting block 43. The spring 45 is sleeved on the periphery of the sliding rod 42, and the two ends of the spring 45 abut against the limiting block 43 and the positioning plate 41, respectively.

[0022] The fixed mold mounting plate 2 is provided with screws 22 on the front side, and the fixed mold mounting plate 2 is fixedly connected to the fixed mold station of the magnesium alloy die casting machine body 1 by screws 22.

[0023] The fixed mold mounting plate 2 has a through injection hole 21 on its front side, and four sets of positioning components 23 are provided on its front side.

[0024] The positioning component 23 includes a positioning rod 231 and a hemispherical block 232. The positioning rod 231 is fixedly connected to the front of the fixed mold mounting plate 2, and the hemispherical block 232 is fixedly connected to the end of the positioning rod 231 away from the fixed mold mounting plate 2.

[0025] The fixed mold 3 has a through injection hole 31 on its back side. The fixed mold 3 has two sets of limiting grooves 32 on both the left and right sides. The fixed mold 3 has four sets of positioning grooves on its back side. The positioning rod 231 is slidably connected inside the adjacent positioning groove. The inner wall size of the positioning groove is the same as the circumferential side size of the positioning rod 231.

[0026] The magnesium alloy die casting machine body 1 is equipped with a limiting mechanism 1 8 and a limiting mechanism 2 9. The limiting mechanism 1 8 is located above the fixed mold station of the magnesium alloy die casting machine body 1, and the limiting mechanism 2 9 is located above the moving mold station of the magnesium alloy die casting machine body 1. The limiting mechanism 2 9 has the same structure as the limiting mechanism 1 8.

[0027] The limiting mechanism 8 includes a fixed plate 81, a positive and negative threaded rod 82, and a guide rod 83. The fixed plate 81 is fixedly connected above the fixed mold station of the magnesium alloy die casting machine body 1, and there are two sets of fixed plates 81. The positive and negative threaded rod 82 is rotatably connected between the two sets of fixed plates 81, and the guide rod 83 is fixedly connected between the two sets of fixed plates 81.

[0028] The limiting mechanism 8 also includes a slider 84, a limiting plate 85, and a handwheel 86. The slider 84 is slidably connected to the side of the guide rod 83, and there are two sets of sliders 84. Both sets of sliders 84 are threadedly connected to the positive and negative threaded rods 82. The limiting plate 85 is fixedly connected to the bottom of the slider 84, and there are two sets of limiting plates 85 located at the bottom of the slider 84. The handwheel 86 is fixedly connected to the positive and negative threaded rods 82. The top of the connecting plate 44 is located between the two adjacent sets of limiting plates 85.

[0029] In summary, the magnesium alloy die-casting device with a quick-change locking structure provided by this utility model allows for the rotation of the forward and reverse threaded rods 82 by turning the handwheel 86 during operation. This rotation causes two sets of sliders 84 to slide along the guide rod 83, allowing them to move away from each other. As the sliders move away, the two limiting plates 85 near the center of the forward and reverse threaded rods 82 press against the adjacent connecting plates 44. The connecting plates 44 then slide the limiting blocks 43 out of the limiting groove 32 via the sliding rod 42, facilitating the removal of the fixed mold 3. After removing the fixed mold 3, the sliders 84 can be reset by turning the handwheel 86 in the opposite direction. The spring force of the spring 45 then resets the limiting blocks 43, aligning the positioning groove on the back of the fixed mold 3 with the hemispherical block 232. With the back of the fixed mold 3 facing the front of the fixed mold mounting plate 2, and the fixed mold 3 moved toward the fixed mold mounting plate 2, the fixed mold 3 can press against the limiting block 43. The limiting block 43 is pressed and moves toward the positioning plate 41. When the fixed mold 3 and the fixed mold mounting plate 2 are in contact, the four sets of positioning components 23 are located inside the four adjacent positioning grooves. At the same time, the limiting block 43 is located inside the adjacent limiting groove 32. At this time, if the handwheel 86 is rotated in the opposite direction, the two sets of limiting plates 85 far from the center of the positive and negative thread screws 82 can press against the connecting plate 44. At this time, the inclined edge of the limiting block 43 near the fixed mold mounting plate 2 can press against the inner wall of the limiting groove 32, so that the fixed mold 3 and the fixed mold mounting plate 2 can be tightly attached, so that the magnesium alloy solution can be injected normally into the space between the fixed mold 3 and the moving mold 6 through the injection hole 1 21 and the injection hole 2 31.
