Description

Technical Field

[0001] This utility model relates to the field of casting equipment technology, and more specifically, to a multi-functional casting machine. Background Technology

[0002] A pressure casting machine is a device used to rapidly inject molten metal into a mold under pressure to produce high-precision castings. The casting process typically involves first injecting molten metal into the mold cavity under pressure, then holding the pressure, cooling, and finally releasing the pressure to open the mold and remove the part.

[0003] In pressure casting, the solidification of castings typically begins with cooling from the outside and the side furthest from the gating gate. This can lead to shrinkage porosity on the interior and the surface furthest from the gating gate. Currently, pressure holding is used to minimize shrinkage porosity, but this method requires higher pressure equipment and molds with greater precision and airtightness, significantly increasing costs.

[0034] Example

[0035] Combination Figures 1 to 5 As shown, this embodiment provides a multifunctional casting machine, including a furnace 1 that can inject molten metal into a mold 18 under pressure through a pouring port 12; and a robot arm that can close the mold 18, which has a pouring port on its side, and move the mold 18 to bring the pouring port closer to or away from the pouring port 12; the furnace has an inclined pouring channel 16 inside, which passes through the upper side of the furnace 1 to form the pouring port 12; the robot arm is mounted on a base, and a first drive 7 is provided on the base, which can drive the robot arm to rotate along the axis of the pouring port 12.

[0036] In this embodiment, as Figure 1 and Figure 2As shown, the robotic arm is mounted on the frame 2. It includes a first robotic arm 3 and a second robotic arm 4, with a first fixture 5 and a second fixture 6 respectively at their ends, used to clamp two molds 18 that can be closed. A second drive 8 is provided on the base to drive the first robotic arm 3 and the second robotic arm 4 to move closer or further apart, so as to realize the closing and opening of the molds 18. The first fixture 5 and the second fixture 6 are respectively rotatably disposed at the ends of the first robotic arm 3 and the second robotic arm 4; and the first robotic arm 3 and the second robotic arm 4 are respectively provided with a third drive 9, which is a hydraulic cylinder used to drive the fixture to rotate, thereby causing the cavity opening of the mold 18 to rotate outward, facilitating the demolding of the molded parts.

[0037] In this embodiment, a fourth drive 10 is also provided on the base to drive the robot arm to move vertically, thereby adjusting the height of the mold 18 so that the pouring gate is adjusted to the same height as the injection port 12. A sixth drive 11 is provided on the base to drive the robot arm to move horizontally, so that the pouring gate of the mold 18 seals against the injection port 12. A fifth drive 13 is also provided on the frame 2 to drive the robot arm to rotate, so as to cooperate with the fourth drive 10 to lower the mold 18 into the cooling tank or the graphite tank 19. The base is rotatably mounted on the base 15, and a seventh drive 14 drives the base to rotate along the vertical axis, so that the mold 18 can rotate and switch between the loading / unloading station and the injection station.

[0038] In this embodiment, as Figure 4 and Figure 5 As shown, the furnace 1 has an inclined injection channel 16 extending through its upper side, and the injection port 12 on the upper side of the injection channel 16 has an outwardly protruding injection boss 17. The mold 18 rotates along the horizontal axis of the injection boss 17 under the drive of the first drive 7, and the inclined injection channel 16 facilitates the smooth injection of molten metal into the cavity of the mold 18. The inclined injection channel 16 extending through the upper side of the furnace 1 allows the molten metal to be injected more smoothly into the mold cavity, while also preventing molten metal from clogging the injection channel 16. Even if some molten metal adheres to the injection channel 16, it is easy to clean it later.

[0039] In this embodiment, the pouring gate is located on the lower side of the mold 18 so that after the mold 18 is flipped over, a larger cavity is placed below the pouring gate, so as to better utilize gravity for shrinkage compensation.

[0040] The casting process of this multi-functional casting machine is described below, such as... Figure 2 As shown in the top view, the furnace 1 is located at the injection station on the right, and the loading and unloading station is in front.

[0041] like Figures 2 to 5 As shown. First, the robotic arm with mold 18 installed rotates to the loading / unloading station under the drive of the seventh drive 14, placing the core into the mold 18. Driven by the second drive 8, the first robotic arm 3 and the second robotic arm 4 move closer together, causing the mold 18 to close. Then, driven by the seventh drive 14, the robotic arm rotates to the injection station. Driven by the fourth drive 10, the height of the sprue is adjusted to be coaxial with the injection port 12. Then, the sixth drive 11 moves the mold 18 to the right, bringing the sprue against the injection port 12. Subsequently, the furnace 1 injects molten metal into the cavity of the mold 18 using pressure, and then... The first drive 7 drives the mold 18 to rotate at a certain angle along the axis of the injection port 12, and holds the pressure for a certain period of time after the cavity is filled with molten metal. Finally, driven by the seventh drive 14, the mold 18 rotates to the loading and unloading station. Then, driven by the second drive 8, the first robot 3 and the second robot 4 move away from each other and drive the mold 18 to open the mold and unload the part. After the unloading is completed, the third drive 9 drives the fixture to rotate outward, and at the same time, the fifth drive 13 drives the robot to rotate downward. At this time, driven by the fourth drive 10, the mold 18 is lowered into the cooling tank below for cooling, or lowered into the graphite tank 19 for graphite coating.

[0042] It should be noted that the holding time and the angle of rotation along the axis of the injection port 12 are specifically set according to the different parts being molded. Taking a die-cast thin-walled part as an example, its injection port is located on the lower side of the mold 18; when the injection port abuts against the injection port 12, the furnace 1 begins to hydraulically inject molten metal into the cavity of the mold 18; at this time, the first drive 7 begins to drive the mold 18 to rotate along the axis of the injection port 12 until it rotates 180 degrees, so that most of the cavity is placed below the injection port; after the molten metal fills the cavity, it is held under pressure for about 5 seconds, and then the pressure is released to rotate the mold 18 to the loading and unloading station for mold opening and unloading; in this way, a thin-walled casting without shrinkage porosity is obtained.

[0043] The multi-functional casting machine described above can rotate the mold 18 along the axis of the injection port 12, which can both maintain pressure inside the cavity of the mold 18 and rotate it at a certain angle according to different parts to achieve feeding through the gravity of the molten metal itself. This method achieves dual feeding through pressure maintenance and gravity, which greatly reduces the problem of shrinkage inside and outside the parts; and its structure is simple and the cost is low.

[0044] Of course, in other embodiments, such as Figure 12 and Figure 13 As shown, the interior of the furnace 1 can also have multiple injection channels 16 arranged horizontally in parallel; the mold 18 can have one pouring port adapted to the injection port 12 of one of the injection channels 16, or multiple pouring ports adapted to the injection ports 12 of multiple injection channels 16 respectively. When the mold 18 has one injection port 12, the mold can vertically part the product in the vertical direction, that is, the cavity inside the mold is roughly divided into left and right parts. The injection port 12 is set on the vertical parting line, and it can rotate along the axis of the injection port 12 under the drive of the first drive 7, so as to achieve feeding by the gravity of the molten metal itself; at the same time, the injection ports 12 of the other injection channels 16 are blocked by plugs (not shown in the figure) to prevent the molten metal from flowing out from other injection channels when the mold is flipped. When the mold 18 is provided with a plurality of injection ports 12 that are respectively adapted to the injection ports 12 of the plurality of injection channels 16, the mold performs horizontal parting of the product along the horizontal surface, and the injection ports are set on the parting line; the setting of the plurality of injection channels is suitable for injection of large products, which can realize rapid filling of the product and has a lower pressure requirement for injection, thereby improving the quality of the product.

[0045] In other embodiments, such as Figure 6 and Figure 7 As shown, a second injection port 20 can also be provided directly above the furnace 1. For some ordinary parts that do not have high requirements for appearance, they only need to be filled and then held under pressure. Therefore, the injection port of the mold can be directly set at the bottom. When the robot moves the mold to directly above the furnace 1, the injection port of the mold is brought into contact with the second injection port 20 to carry out filling and holding pressure, thereby realizing conventional pressure casting.

[0046] In another embodiment, such as Figure 8 and Figure 11As shown, two robotic arms 21 are symmetrically arranged on the base. One robotic arm can clamp the mold and close it, then use a flipping mold to seal the pouring gate against the injection port 12 on the side of the furnace, followed by injection, flipping, and pressure holding molding processes to cast parts with high appearance requirements or thin-walled parts. The other robotic arm clamps the mold and closes it, then uses a flipping mold to seal the pouring gate against the second injection port 20 directly above the furnace, followed by injection and pressure holding molding to cast ordinary parts with lower appearance requirements. This method allows for the casting of multiple parts using the same furnace. Of course, it can also be used to cast the same part, with one robotic arm clamping the mold for die casting and other processes, while the other robotic arm clamps the mold to insert the core. In this way, the two molds can work continuously, reducing the waiting time for core insertion when one mold is working.

[0047] Of course, it should be noted that symmetrically arranging two robotic arms 21 is only one feasible solution. Alternatively, four robotic arms can be evenly distributed on the base, each holding a molding die. One feasible casting method involves the first robotic arm, after the die in the first robotic arm is cast, rotating 90 degrees to the unloading position, while the other robotic arm rotates 90 degrees to the casting position. At this point, the unloading and casting of the parts can be performed simultaneously; this process can be repeated to achieve continuous casting and improve efficiency.

[0048] Of course, the base 15 in the above embodiments can be installed on the mounting base 22 (e.g., Figure 7 (as shown), or it can be hoisted using a suspension base 23 (as shown). Figure 11 (As shown).
