Description

Technical Field

[0001] This utility model relates to the field of ingot mold technology, and in particular to a split magnesium alloy ingot mold. Background Technology

[0002] Magnesium alloys, as the lightest metallic structural material currently used in industrial applications, are increasingly in demand in aerospace, automotive manufacturing, and 3C electronics due to their high specific strength, excellent shock absorption, and good electromagnetic shielding performance. Magnesium alloys are generally produced using a semi-solid casting process. However, the interfacial tension between the solid particles and liquid metal in the semi-solid magnesium alloy slurry is relatively high. During the filling process, local solidification can easily occur due to temperature fluctuations on the mold surface, forming "micro-adhesion points." As the solidification process progresses, these adhesion points gradually expand into large areas of mold adhesion, making it difficult to demold the magnesium alloy by adhering to the inner wall of the mold.

[0003] Therefore, this application provides a split magnesium alloy ingot mold. Utility Model Content

[0004] This invention provides a split magnesium alloy ingot mold, which can solve the problem that traditional magnesium alloy casting molds are prone to local solidification due to temperature fluctuations on the mold surface during the magnesium alloy filling process, forming "micro-adhesion points". As the solidification process progresses, these adhesion points will gradually expand into large-area adhesion, causing the magnesium alloy to stick to the inner wall of the mold and making it difficult to demold during the demolding process.

[0005] This utility model provides a split magnesium alloy ingot mold, comprising:

[0006] A mold mechanism includes a lower mold and an upper mold, wherein a movable cavity is provided at the center of the upper end of the lower mold and an mounting cavity is provided at the center of the lower wall of the upper mold;

[0007] The demolding mechanism includes a connecting frame fixedly installed on one side of the lower mold, a moving plate slidably connected inside the moving cavity, and a pressure plate slidably connected inside the mounting cavity. A cylinder is fixedly installed on one side of the connecting frame, and the output end of the cylinder is fixedly connected to one side of the moving plate.

[0008] In a split-type magnesium alloy ingot mold according to one embodiment of the present invention, a ventilated steel is fixedly installed inside the movable plate, and a connecting air pipe is provided on one side of the movable plate, the connecting air pipe being interconnected with the ventilated steel.

[0009] In a split magnesium alloy ingot mold according to one embodiment of the present invention, guide holes are provided at the four corners of the upper surface of the lower mold, and guide rods are fixedly installed at the four corners of the lower wall of the upper mold.

[0010] In a split magnesium alloy ingot mold according to one embodiment of the present invention, the lower wall of the pressure plate and the upper wall of the movable plate are provided with mutually compatible inclined surfaces, and a fixed installation is provided inside the movable cavity.

[0011] In a split-type magnesium alloy ingot mold according to one embodiment of the present invention, a scraper is fixedly installed on the right side of the lower wall of the pressure plate.

[0012] In a split-type magnesium alloy ingot mold according to one embodiment of the present invention, a spring rod is fixedly installed between the pressure plate and the mounting cavity.

[0013] In a split magnesium alloy ingot mold according to one embodiment of the present invention, lifting holes are provided on the outer walls of both the left and right sides of the upper mold.

[0014] In a split magnesium alloy ingot mold according to one embodiment of the present invention, an electric heating wire is fixedly installed inside the lower mold, and the electric heating wire is arranged in a corrugated shape inside the lower mold.

[0015] The technical solution provided in this application embodiment can include the following beneficial effects: This application designs a split magnesium alloy ingot mold. By sliding a moving plate inside the moving cavity, after the magnesium alloy casting is completed, the moving plate is moved to the left along the moving cavity by the operation of a cylinder, thereby causing the bottom of the magnesium alloy ingot to separate from the moving plate. On the one hand, the bottom of the magnesium alloy mold is demolded first, reducing the damage to the casting caused by the instantaneous concentration of demolding force. On the other hand, after the moving plate is removed, the continuity of the overall adhesion of the magnesium alloy is broken, which facilitates the demolding of the magnesium alloy. First, inert gas is injected into the inside of the ventilated steel through the connecting air pipe. The inert gas is blown to the bottom of the magnesium alloy through the ventilated steel to form an isolation layer. On the one hand, the isolation layer can reduce the direct contact between the metal and the mold, assisting separation. On the other hand, the inert gas prevents the magnesium alloy from oxidizing.

[0023] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] like Figures 1 to 4 As shown, this application provides a split magnesium alloy ingot mold, comprising:

[0026] The mold mechanism 100 includes a lower mold 10 and an upper mold 20. The lower mold 10 has a moving cavity 12 at its upper center and the upper mold 20 has an installation cavity 21 at its lower center. The demolding mechanism 30 includes a connecting frame 31 fixedly installed on one side of the lower mold 10, a moving plate 33 slidably connected inside the moving cavity 12, and a pressure plate 35 slidably connected inside the installation cavity 21. A cylinder 32 is fixedly installed on one side of the connecting frame 31, and the output end of the cylinder 32 is fixedly connected to one side of the moving plate 33.

[0027] After adopting the above technical solution, by sliding the moving plate 33 inside the moving cavity 12, after the magnesium alloy casting is completed, the moving plate 33 is moved to the left along the moving cavity 12 by the operation of the cylinder 32, thereby causing the bottom of the magnesium alloy ingot to separate from the moving plate 33. On the one hand, the bottom of the magnesium alloy mold is demolded first, reducing the damage to the casting caused by the instantaneous concentration of demolding force. On the other hand, after the moving plate 33 is pulled out, the continuity of the overall adhesion of the magnesium alloy is broken, which facilitates the demolding of the magnesium alloy.

[0028] It should be noted that during the mold closing process, the cylinder 32 first pushes the moving plate 33 from the left side to the right side of the moving cavity 12, and then the lower mold 10 and the upper mold 20 are combined to achieve mold closing. During this process, the pressure plate 35 and the moving plate 33 come into contact and combine, so that the moving plate 33, the pressure plate 35 and the moving cavity 12 form a forming cavity. After the raw material is poured into the forming cavity and cooled, the magnesium alloy ingot casting operation is completed. After the magnesium alloy ingot is completed, inert gas is first injected into the ventilated steel 37 through the connecting air pipe 38. The inert gas is blown to the bottom of the magnesium alloy through the ventilated steel 37 to form an isolation layer. On the one hand, this isolation layer can reduce the direct contact between the metal and the mold. Contact and assisted separation, and on the other hand, inert gas is used to prevent magnesium alloy oxidation. At this time, the cylinder 32 works to move the moving plate 33 to the left along the moving cavity 12, thereby pulling the moving plate 33 away from the bottom of the magnesium alloy. On the one hand, the bottom of the magnesium alloy mold is demolded first, reducing the damage to the casting caused by the instantaneous concentration of demolding force. On the other hand, after the moving plate 33 is pulled away, the continuity of the overall adhesion of the magnesium alloy is broken, which facilitates the demolding of the magnesium alloy. During the movement of the moving plate 33, the scraper 36 on the lower wall of the pressure plate 35 contacts the upper wall of the moving plate 33 and scrapes off the impurities adhering to the moving plate 33. The staff only needs to use a vacuum cleaner to remove the impurities, reducing the workload of the staff.

[0029] In an optional embodiment, a ventilated steel 37 is fixedly installed inside the movable plate 33. A connecting air pipe 38 is provided on one side of the movable plate 33. The connecting air pipe 38 is connected to the ventilated steel 37. First, inert gas is injected into the ventilated steel 37 through the connecting air pipe 38. The inert gas is blown to the bottom of the magnesium alloy through the ventilated steel 37 to form a gas isolation layer. On the one hand, the isolation layer can reduce the direct contact between the metal and the mold, which helps to separate the parts. On the other hand, the inert gas can prevent the magnesium alloy from oxidizing.

[0030] In one optional embodiment, guide holes 13 are provided at the four corners of the upper surface of the lower mold 10, and guide rods 23 are fixedly installed at the four corners of the lower wall of the upper mold 20. By setting the guide holes 13 and guide rods 23, the lower mold 10 and the upper mold 20 can be accurately fitted together when the mold is closed.

[0031] In an optional embodiment, the lower wall of the pressure plate 35 and the upper wall of the moving plate 33 are provided with mutually compatible inclined surfaces. The moving cavity 12 is fixedly installed on one side. During the process of moving the moving plate 33 to pull the core, the inclined surfaces can prevent interference between the moving plate 33 and the pressure plate 35, making it easier for the moving plate 33 to move. At the same time, the 14 is used to limit the pressure plate 35.

[0032] In one optional embodiment, a scraper 36 is fixedly installed on the right side of the lower wall of the pressure plate 35. During the movement of the moving plate 33, the scraper 36 on the lower wall of the pressure plate 35 contacts the upper wall of the moving plate 33 and scrapes off the impurities adhering to the moving plate 33. The staff only needs to use a vacuum cleaner to remove the impurities, reducing the workload of the staff.

[0033] In an optional embodiment, a spring rod 34 is fixedly installed between the pressure plate 35 and the mounting cavity 21. During the mold closing process, the spring rod 34 pushes the pressure plate 35 downward, thereby making the pressure plate 35 and the moving plate 33 tightly connected and improving the sealing of the molding cavity. On the other hand, during the core pulling process, the spring rod 34 pushes the pressure plate 35 downward, thereby making the scraper 36 stick tightly to the upper wall of the moving plate 33 and improving its impurity removal effect.

[0034] In one optional embodiment, lifting holes 22 are provided on the outer walls of both the left and right sides of the upper mold 20, which facilitates the lifting of the upper mold 20.

[0035] In an optional embodiment, an electric heating wire 11 is fixedly installed inside the lower mold 10, and the electric heating wire 11 is arranged in a corrugated shape inside the lower mold 10. During the magnesium alloy ingot casting process, the lower mold 10 is heated by the electric heating wire 11, which can prevent the magnesium alloy raw material from solidifying too early after entering the lower mold 10.
