Abstract
Description
Technical Field
[0001] This invention relates to the field of die casting technology, and more specifically, to a die casting machine. Background Technology
[0002] Depending on the material being produced, die-casting machines are typically categorized into aluminum alloy die-casting machines, magnesium alloy die-casting machines, and so on. Traditional die-casting machines are mostly single-type machines, capable of producing die-cast parts from specific materials, such as aluminum alloys or magnesium alloys, making it difficult to freely and conveniently switch between different materials. When the production material needs to be changed, large-scale adjustments to the melting and transportation production lines are often required, resulting in high costs.
[0003] In magnesium alloy die casting, the conventional method is similar to that for aluminum alloys: liquid magnesium is poured directly into an open injection cylinder exposed to air, and then injected into the mold through an injection system. Because liquid magnesium is highly susceptible to oxidation, magnesium alloy products produced by this method often contain many impurities and have poor performance; furthermore, liquid magnesium is flammable, requiring extremely high safety standards. Another method is a screw-type semi-solid magnesium alloy die casting machine. This machine achieves complete enclosure of the liquid magnesium, avoiding oxidation and combustion risks, and the semi-solid magnesium alloy can be directly transferred to the mold for forming. However, this method requires a screw and a container for the semi-solid alloy within the slurry cylinder before being pressed into the mold, making high-speed, high-pressure injection impossible, thus limiting product forming efficiency. Furthermore, neither of these types of magnesium alloy die casting machines can be directly switched to aluminum alloy die casting mode. Summary of the Invention
[0004] To address the aforementioned technical problems, this invention provides a die-casting machine that can conveniently switch between two die-casting modes: magnesium alloy die-casting and aluminum alloy die-casting. It also supports high-speed, high-pressure injection, enabling high-performance, multi-material die-casting production.
[0005] According to one embodiment of the present invention, a die-casting machine is provided, comprising: a fixed mold plate, one end face of which has a mounting groove, and at least one side face of which has a mounting hole communicating with the mounting groove, and the bottom surface of the mounting groove has a fixing hole; an injection assembly, one end of which is provided with an injection hammer head opposite to the mounting groove; a first injection cylinder, the side wall of which has a through hole, one end of which has a first injection hole, and the other end of which has a first discharge port; a second injection cylinder, the side wall of which has an inlet, one end of which has a second injection hole, and the other end of which has a second discharge port; and a first molten material supply device, disposed on the side of the fixed mold plate, one end of which is connected to the mounting groove. The device includes a third discharge port opposite to the mounting hole; a second molten material supply device with a feeding structure capable of multi-degree-of-freedom movement; wherein, in the first molten material die-casting mode, the first injection cylinder is fixed in the mounting groove, the through hole is connected to the third discharge port, the first discharge port is connected to the fixing hole, and the injection hammer is slidably disposed in the first injection hole; in the second molten material die-casting mode, the second injection cylinder is fixed in the mounting groove, the second discharge port is connected to the fixing hole, the injection hammer is slidably disposed in the second injection hole, and the feeding structure can move to the inlet.
[0006] As one embodiment, the fixed template has mounting holes on both sides that communicate with the mounting groove; the discharge end of the first molten material supply device is slidably disposed in one of the mounting holes, and a first hydraulic cylinder is disposed in the other mounting hole, with the movable end of the first hydraulic cylinder being disposed opposite to the first injection cylinder.
[0007] As one embodiment, the fixed template has mounting holes on both sides that communicate with the mounting groove, and the first molten material supply device is provided at each of the two mounting holes. The discharge end of the first molten material supply device is slidably disposed in the mounting hole, and two through holes are symmetrically provided on the side wall of the first injection cylinder.
[0008] As one embodiment, the die-casting machine further includes: a second hydraulic cylinder, one end of which is connected to the fixed template and the other end of which is connected to the first molten material supply device, for driving the first molten material supply device to slide along the depth direction of the mounting hole.
[0009] As one embodiment, the die-casting machine further includes: a slide table, fixedly disposed on the side of the fixed template, on which a slide rail parallel to the second oil cylinder is formed; wherein, the first molten material supply device is slidably disposed on the slide rail.
[0010] In one embodiment, the first molten material supply device includes: a slurry cylinder with the third discharge port at one end, a discharge port on the side wall, and a screw with helical blades rotatably mounted inside, and a valve at the third discharge port; and a drive device connected to the screw and capable of driving the screw to rotate.
[0011] In one embodiment, the injection hammer head is detachably connected to the front end of the injection rod in the feeding assembly.
[0012] In one embodiment, the second molten material supply device further includes a molten material holding furnace and a moving component. The feeding structure is located at the front end of the moving component, and the moving component is used to drive the feeding structure to transfer the molten material in the molten material holding furnace to the inlet.
[0013] In one embodiment, the moving component includes an X-axis moving structure, a Y-axis moving structure, and a Z-axis rotating structure connected in sequence, and the feeding structure is disposed on the Z-axis rotating structure.
[0014] In one embodiment, the first molten material supply device is used to supply magnesium alloy molten material to the first injection barrel; the second molten material supply device is used to supply aluminum alloy molten material to the second injection barrel.
[0015] Based on the above description and practice, it can be seen that in the first molten material die casting mode, the first injection cylinder of the die casting machine of the present invention is fixedly installed in the mounting groove of the fixed template. At this time, the through hole on its side wall is aligned with the mounting hole on the side of the fixed template, and the third outlet of the first molten material supply device is connected to the through hole, thereby realizing the supply of molten material into the first injection cylinder. The first outlet of the first injection cylinder is connected to the fixing hole on the bottom surface of the mounting groove. The injection hammer of the ejector assembly is slidably disposed in the first injection hole. When a sufficient amount of molten material is received, the injection hammer advances to press the molten material in the first injection cylinder into the mold cavity through the fixing hole.
[0016] In the second molten material die casting mode, the first injection cylinder is removed from the mounting slot, and the second injection cylinder is fixedly installed in the mounting slot. At this time, the second outlet of the second injection cylinder is connected to the fixing hole, and the injection hammer is slidably disposed in the second injection hole. The feeding structure of the second molten material supply device, through its multi-degree-of-freedom movement capability, adds molten material to the inlet of the second injection cylinder. The advancement of the injection hammer allows the molten material in the second injection cylinder to be pressed into the mold cavity through the fixing hole.
[0017] The die-casting machine of this invention includes a first molten material supply device, a second molten material supply device, a first injection cylinder, and a second injection cylinder, while only having one feeding assembly. During operation, by setting different injection cylinders within the fixed mold, it is possible to quickly switch between two different molten material die-casting modes. Because both die-casting modes use the same feeding assembly, compared to traditional screw-type semi-solid magnesium alloy die-casting machines, it can support high-speed, high-pressure injection, achieving high-performance, multi-material die-casting production.

[0028] like Figures 1 to 8 As shown, in this embodiment, a die-casting machine is disclosed. Figure 2 To demonstrate the structure of the mounting slot 11 in the die-casting machine, the second molten material supply device 60 is omitted. In this embodiment, the structure of the die-casting machine is described in detail using the first molten material die-casting mode as magnesium alloy die-casting mode and the second molten material die-casting mode as aluminum alloy die-casting mode as examples. In other embodiments, the molten material supplied by the first molten material supply device 50 and the second molten material supply device 60 can be changed according to actual working conditions, enabling the die-casting machine to perform die-casting operations in two different modes.
[0029] The die-casting machine mainly includes a fixed mold plate 10, a feeding assembly 20, a first injection cylinder 30, a second injection cylinder 40, a first molten material supply device 50, and a second molten material supply device 60. This die-casting machine can easily switch between the first molten material die-casting mode and the second molten material die-casting mode, while also supporting high-speed, high-pressure injection, enabling high-performance, multi-material die-casting production.
[0030] The fixed template 10, also known as the head plate, has a mounting groove 11 formed on one end face. This mounting groove 11 is used to accommodate and fix different injection cylinders. At least one side of the fixed template 10 has a mounting hole 12 communicating with the mounting groove 11. The bottom surface of the mounting groove 11 has a fixing hole 13 for assisting in fixing the injection cylinder. After the injection cylinder is fixedly installed in the mounting groove 11, one end of it is opposite to the ejector assembly 20, and the other end is opposite to the mold runner. The ejector assembly 20 can inject the molten material in the injection cylinder into the mold.
[0031] The injection assembly 20 includes an injection cylinder 23 and an injection rod 22 connected thereto. The front end of the injection rod 22 is equipped with an injection hammer 21. The injection hammer 21 is positioned opposite the mounting groove 11 and is used to reciprocate within the injection barrel to push the molten material into the mold. In this embodiment, the injection hammer 21 is detachably connected to the front end of the injection rod 22. When injecting different molten materials, an injection hammer 21 with a suitable melting point that does not react with the molten material can be replaced. Alternatively, an injection hammer 21 with a higher melting point, suitable for both types of molten materials, can be directly installed and replaced only after wear occurs. Furthermore, when switching injection barrels, an injection hammer 21 of the appropriate size can be used according to the orifice diameter of the different barrels to ensure the sealing and stability of the injection process.
[0032] The first injection cylinder 30 and the second injection cylinder 40 are used to convey different molten materials under different die-casting modes. The user can choose to fix one of them in the mounting slot 11 according to actual operational needs. In this embodiment, the first injection cylinder 30 is used to convey the magnesium alloy molten material provided by the first molten material supply device 50. The side wall of the first injection cylinder 30 is provided with a through hole 31, which is opposite to the mounting hole 12. One end of the first injection cylinder 30 is provided with a first injection hole 32 for the injection hammer head 21 to extend into, and the other end is provided with a first discharge port 33. The molten material in the first injection cylinder 30, pushed by the injection hammer head 21, can enter the mold from the first discharge port 33.
[0033] In this embodiment, the second injection barrel 40 is used to transport the molten aluminum alloy supplied by the second molten material supply device 60. The side wall of the second injection barrel 40 is provided with an inlet 41, one end is provided with a second injection hole 42 for the injection hammer head 21 to extend into, and the other end is provided with a second outlet 43. The molten material in the second injection barrel 40 can enter the mold from the second outlet 43 under the push of the injection hammer head 21.
[0034] The first molten material supply device 50 is disposed on the side of the fixed template 10, and one end of it is a third discharge port 51. The position of the third discharge port 51 is opposite to the mounting hole 12, and it is used to supply molten material to the first injection cylinder 30 in the mounting groove 11. The second molten material supply device 60 has a feeding structure 61 that can move with multiple degrees of freedom, and is used to supply molten material to the second injection cylinder 40.
[0035] like Figure 3 As shown, in the first molten material die casting mode, i.e., the magnesium alloy die casting mode, the first injection cylinder 30 is fixedly installed in the mounting groove 11 of the fixed template 10. At this time, the through hole 31 on the side wall of the first injection cylinder 30 is aligned with the mounting hole 12 on the side of the fixed template 10 and is connected to the third outlet 51 of the first molten material supply device 50. The first outlet 33 of the first injection cylinder 30 is set in the fixing hole 13 on the bottom surface of the mounting groove 11 and is connected to the mold's sprue. The injection hammer head 21 of the ejector assembly 20 is slidably set in the first injection hole 32 of the first injection cylinder 30. During operation, the first molten material supply device 50 injects semi-solid magnesium alloy molten material into the first injection cylinder 30 through the third outlet 51 and the through hole 31. Then, the injection hammer head 21 advances at high speed and high pressure under the drive of the ejector assembly 20, pressing the molten material in the first injection cylinder 30 into the mold through the sprue.
[0036] When it is necessary to switch to the second molten material die casting mode, that is, to switch to the aluminum alloy die casting mode, move the third outlet 51 of the first molten material supply device 50 away from the first injection cylinder 30, remove the first injection cylinder 30, and then install and fix the second injection cylinder 40. Molten material is then injected into the second injection cylinder 40 through the second molten material supply device 60 for die casting.
[0037] Specifically, the first injection cylinder 30 is removed from the mounting groove 11, and the second injection cylinder 40 is fixedly installed in the mounting groove 11. At this time, the second outlet 43 of the second injection cylinder 40 is located in the fixing hole 13 on the bottom surface of the mounting groove 11, and the injection hammer 21 is slidably located in the second injection hole 42. The second molten material supply device 60 transfers the liquid aluminum alloy molten material to the inlet 41 of the second injection cylinder 40 and injects it through its movable feeding structure 61. Then, the injection hammer 21 advances at high speed and high pressure under the drive of the ejector assembly 20, pressing the molten material in the second injection cylinder 40 into the mold.
[0038] In the second molten material die casting mode, the first molten material supply device 50 remains separated from the second injection cylinder 40, and the first molten material supply device 50 is in a stopped mode. Similarly, in the first molten material die casting mode, the second molten material supply device 60 is in a stopped mode.
[0039] In this embodiment, a valve is also provided at the third outlet 51 of the first molten material supply device 50. This valve opens when material needs to be supplied to the first injection cylinder 30, and closes when injection operation is required, preventing pressure from being transmitted to the first molten material supply device 50. Therefore, during magnesium alloy die casting, the first molten material supply device 50 is only used to provide magnesium alloy molten material and does not need to provide injection pressure. The injection molten material is supplied by the feeding assembly 20, thus achieving the same high-speed, high-pressure injection as aluminum alloy die casting.
[0040] The die-casting machine of this invention includes a first molten material supply device 50, a second molten material supply device 60, a first injection cylinder 30, and a second injection cylinder 40, while only one feeding assembly 20 is provided. During operation, by setting different injection cylinders within the fixed mold platen 10, it is possible to quickly switch between two different molten material die-casting modes. Since the two die-casting modes use the same feeding assembly 20, compared to traditional screw-type semi-solid magnesium alloy die-casting machines, it can support high-speed, high-pressure injection, achieving high-performance, multi-material die-casting production.
[0041] In this embodiment, the fixed template 10 has mounting holes 12 on both opposite sides that communicate with the mounting groove 11. The discharge end of the first molten material supply device 50 is slidably disposed in one mounting hole 12. A first hydraulic cylinder 70 is disposed in the other mounting hole 12, with its movable end extending into the mounting groove 11 and positioned opposite to the first injection cylinder 30. When the first injection cylinder 30 is installed, the first hydraulic cylinder 70 extends and its movable end abuts against the side of the first injection cylinder 30, and the third discharge port 51 of the first molten material supply device 50 abuts against the through hole 31 of the first injection cylinder 30. The first hydraulic cylinder 70 and the first molten material supply device 50 cooperate to clamp and fix the first injection cylinder 30 in the mounting groove 11, ensuring that the first discharge port 33 is opposite to the mounting hole 12. When it is necessary to switch injection cylinders, the first hydraulic cylinder 70 and the first molten material supply device 50 retract, and the first injection cylinder 30 can be removed. This structure facilitates the installation and fixing of the first injection cylinder 30.
[0042] Furthermore, a positioning groove 34 is provided at the position of the first injection cylinder 30 opposite to the first oil cylinder 70. When the first oil cylinder 70 extends, the movable end is tightly pressed against the positioning groove 34. It cooperates with the first molten material supply device 50 to prevent the position of the first injection cylinder 30 from shifting or to prevent the first injection cylinder 30 from rotating.
[0043] In one embodiment, the fixed template 10 has mounting holes 12 on two opposite sides that communicate with the mounting groove 11. A first molten material supply device 50 is provided in each of the two mounting holes 12, with the discharge end of the first molten material supply device 50 slidably disposed within the mounting hole 12. Two through holes 31 are symmetrically provided on the side wall of the first injection cylinder 30. When the first injection cylinder 30 is installed, the third discharge ports 51 of the two first molten material supply devices 50 respectively abut against the two through holes 31 of the first injection cylinder 30. The two first molten material supply devices 50 cooperate to clamp and fix the first injection cylinder 30 within the mounting groove 11, ensuring that the first discharge port 33 is opposite to the mounting hole 12. When it is necessary to switch injection cylinders, the two first molten material supply devices 50 retract, allowing the first injection cylinder 30 to be removed. This structure also facilitates the installation and fixing of the first injection cylinder 30 within the mounting groove 11 and enables rapid supply of molten material to the first injection cylinder 30.
[0044] The two first molten material supply devices 50 can supply molten material to the first injection cylinder 30 simultaneously, or they can supply molten material to the first injection cylinder 30 sequentially according to actual working conditions. For example, when the molten material preparation time is long, the molten material can be supplied to the first injection cylinder 30 sequentially. While one molten material supply device is supplying material, the other molten material supply device is preparing the molten material, which can improve the die casting efficiency.
[0045] In this embodiment, to facilitate the docking and separation of the first molten material supply device 50 and the first injection cylinder 30, the die-casting machine further includes a second hydraulic cylinder 80 and a slide table 90. One end of the second hydraulic cylinder 80 is connected to the fixed template 10, and the other end is connected to the first molten material supply device 50, used to drive the first molten material supply device 50 to slide along the depth direction of the mounting hole 12. The slide table 90 is fixedly mounted on the side of the fixed template 10, and a slide rail 91 parallel to the second hydraulic cylinder 80 is formed on it, and the first molten material supply device 50 is slidably mounted on the slide rail 91. In the first molten material die-casting mode, the second hydraulic cylinder 80 shortens, pushing the third outlet 51 of the first molten material supply device 50 into the mounting hole 12, tightly docking with the through hole 31 of the first injection cylinder 30. When it is necessary to switch to the second molten material die-casting mode, the second hydraulic cylinder 80 extends, pulling the first molten material supply device 50 out of the mounting hole 12, providing space for replacing the injection cylinder.
[0046] In this embodiment, the first molten material supply device 50 is specifically a slurry-making device for preparing and conveying semi-solid magnesium alloy. It includes a slurry-making cylinder 52 and a drive device 54. One end of the slurry-making cylinder 52 has a third outlet 51, and the side wall has a feed port 53 for feeding raw materials. A screw with helical blades is rotatably mounted inside the slurry-making cylinder 52. The drive device 54 is connected to the screw and drives it to rotate. The raw material enters the slurry-making cylinder 52 through the feed port 53, and under the shearing, stirring, and conveying action of the screw blades, it is heated and formed into a semi-solid slurry, which is finally extruded from the third outlet 51. To precisely control the temperature, the side wall of the slurry-making cylinder 52 is also equipped with a heating device, such as a resistance heating coil or an induction heating coil.
[0047] In other embodiments, the first molten material supply device 50 can also be a plunger type or other existing molten material supply method, all of which can provide molten material to the first injection cylinder 30.
[0048] In this embodiment, the second molten material supply device 60 is mainly used to supply liquid metal, such as molten aluminum alloy. It includes a molten material holding furnace 62 and a moving assembly. The molten material holding furnace 62 is used to store and hold the molten material. The feeding structure 61 is located at the front end of the moving assembly. The moving assembly is used to drive the feeding structure 61 to move, so as to scoop the molten material from the molten material holding furnace 62 and move it to the inlet 41 of the second injection cylinder 40 for pouring. In order to achieve flexible positioning, the moving assembly may include an X-axis moving structure 63, a Y-axis moving structure 64 and a Z-axis rotating structure 65 connected in sequence. The feeding structure 61 is located on the Z-axis rotating structure 65, so as to realize the horizontal and vertical movement and tilting action of the feeding structure 61 to complete the material picking and pouring.
[0049] In this embodiment, the second molten material supply device 60 is a beam-type soup feeder, and the feeding structure 61 is a rotating soup ladle. In other embodiments, the second molten material supply device 60 may also be configured as a robotic arm soup feeder, a linkage mechanism soup feeder, a quantitative furnace soup feeder, etc.
[0050] The magnesium alloy die-casting machine employs an independent injection cylinder and feeding assembly 20, enabling high-speed, high-pressure injection. This overcomes the low pressure-bearing capacity of traditional screw-type semi-solid die-casting machines. Simultaneously, the enclosed first molten material supply device 50 and first injection cylinder 30 ensure that the magnesium alloy is isolated from air throughout the entire process from slurry preparation to injection, avoiding the risks of oxidation and combustion. The aluminum alloy die-casting mode utilizes a movable feeding structure 61 for casting, offering flexibility and reliability. Both modes share the same feeding assembly 20, enabling high-speed, high-pressure injection and pressurized filling. Switching between the two modes is convenient and quick, significantly improving equipment utilization and production flexibility, and reducing equipment costs for multi-material production.
[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
