Description

Technical Field

[0001] This invention relates to the field of die casting technology, and more particularly to an integrated die casting apparatus and method for automotive structural components. Background Technology

[0002] Die casting is a metal casting process characterized by applying high pressure to molten metal within a mold cavity. The molds are typically made of high-strength alloys. The process is somewhat similar to injection molding. Due to the high cost of casting equipment and molds, die casting is generally only used for mass production of large quantities of products. Manufacturing die-cast parts is relatively easy, generally requiring only four main steps with minimal incremental cost per component. Die casting is particularly suitable for manufacturing large quantities of small to medium-sized castings, making it one of the most widely used casting processes. Compared to other casting technologies, die casting produces smoother surfaces and exhibits greater dimensional consistency.

[0045] The traditional die casting process mainly consists of four steps, or high-pressure die casting. The four steps include mold preparation, filling, injection, and shakeout, which are also the basis of various modified die casting processes. In the preparation process, a lubricant needs to be sprayed into the mold cavity, which can help control the temperature of the mold and also help the casting to be demolded. Then the mold can be closed, and the molten metal is injected into the mold under high pressure, which is about 10 to 175 megapascals. When the molten metal is filled, the pressure is maintained until the casting solidifies. Then the ejector rod pushes out all the castings, and since there may be multiple mold cavities in one mold, multiple castings may be produced in each casting process. The shakeout process separates the residues, including the mold gate, runner, sprue, and flash. This process is usually completed by extruding the casting through a special trimming mold. Other shakeout methods include sawing and grinding. If the sprue is brittle, the casting can be directly dropped, which can save labor. The excess mold gate can be reused after melting. The usual yield is about 67%.

[0046] The working principle of the embodiment is as follows: in actual use, first, the first hydraulic telescopic rod 7 is used to move the movable die plate 6 and the mold installed thereon, so that the mold is combined with the mold on the fixed die plate 3, and the movable die plate 6 moves the hinged rod 16 and can move the bearing plate 15 downward, when the two molds are combined, the two round protrusions 27 and the hinged plate 19 are not in contact (because the movable plate 23 deviates to the direction of the bearing plate 15 when the mold is closed, so that the round protrusion 27 and the hinged plate 19 are not in contact, when the mold is opened, the L-shaped column 25 has a force on the movable plate 23, so that the round protrusion 27 re-contacts the hinged plate 19), the two hinged plates 19 are inclined under the action of their own gravity, the first super-high-temperature valve 18 is closed and the second super-high-temperature valve 28 is opened, so that the molten metal in the tank 9 enters the internal of the quantitative barrel 17, then the second super-high-temperature valve 28 is closed and the first super-high-temperature valve 18 is opened, so that the molten metal in the quantitative barrel 17 enters the internal of the feeding pipe 13 through the hopper 12, finally, the second hydraulic telescopic rod 11 drives the piston 14 to move to inject the molten metal into the two molds, after the molten metal between the two molds is formed, the movable die plate 6 is opened through the first hydraulic telescopic rod 7, the movable die plate 6 moves to drive the hinged rod 16 to move, the hinged rod 16 moves to drive the bearing plate 15 to move, the bearing plate 15 moves to drive the L-shaped column 25 to move, the two L-shaped columns 25 move to drive the two movable plates 23 to move (under the action of the gravity of the hinged plate 19), the two movable plates 23 move to drive the two spring rods 26 to move, the two spring rods 26 move to drive the two round protrusions 27 to move, so that the hinged plate 19 can be lifted, the top plate 20 and the top plate 21 are moved through the third hydraulic telescopic rod 22, so that the products in the mold can be pushed out and fall on the bearing plate 15, finally, the above steps are repeated, and when there are products on the bearing plate 15, the hinged plate 19 is inclined to make the products on the bearing plate 15 slide to the conveying belt 8 and be conveyed to the placement area.
