Description

Technical Field

[0001] This utility model relates to the field of die casting machine demolding technology, and in particular to a die casting machine that is easy to demold. Background Technology

[0002] Die casting machines are the core equipment in pressure casting. Their working principle is to inject molten metal (such as aluminum, zinc, etc.) into the mold cavity at high speed under high pressure (usually driven by a hydraulic system). After cooling, the mold is opened to obtain precision metal castings. Initially used for die casting lead type, it is now widely used in the automotive, electronics, and construction industries.

[0003] Currently, after molding, the surface temperature of the die-casting part remains high. Therefore, during the demolding process, the die-casting machine needs to wait for the casting to cool to a certain temperature before it can be easily removed. Existing technologies typically rely on natural cooling, resulting in a long cooling time and reduced demolding efficiency. To address this, we propose a die-casting machine that facilitates demolding. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a die-casting machine that facilitates demolding. By accelerating the cooling of the casting and striking it, the casting is separated from the lower mold, thereby improving the demolding efficiency of the casting.

The striking rods are slidably connected to the base, and a connecting plate is fixedly connected to the bottom end of the striking rod. An elastic element is provided on the outer side of the striking rod, and a reciprocating element is installed at the bottom end of the connecting plate, which facilitates striking the lower mold to separate the casting from the lower mold.

[0011] Preferably, the reciprocating component includes an incomplete gear fixedly connected to the drive shaft, and the outer surface of the incomplete gear meshes with a rack fixedly connected to the connecting plate, which facilitates cooperation with the elastic component to allow the striking rod to move up and down to strike the lower mold.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. Example

[0026] Please see Figures 1-6A die-casting machine for easy demolding includes a control box 1, a body 2 on one side of the control box 1, an upper mold 3 on the body 2, a base 4 at the bottom of the body 2, and a lower mold 5 mounted on the base 4; it also includes a cooling assembly 6, which includes an annular pipe 7 installed between the upper mold 3 and the lower mold 5, with multiple sets of air blowing pipes 8 connected to the annular pipe 7, the multiple sets of air blowing pipes 8 being inclined toward the lower mold 5, and the cooling assembly 6 cooling the casting in the lower mold 5 by blowing air through the multiple sets of inclined air blowing pipes 8; and a striking assembly 9, which is installed inside the base 4 and cooperates with the cooling assembly 6, the striking assembly 9 being used to strike the lower mold 5, causing the lower mold 5 to separate from the casting.

[0027] Please see Figure 3 and Figure 4 The cooling assembly 6 shown in the figure includes a fan shroud 10 installed inside the base 4. One end of the fan shroud 10 has a through hole 11. A fan wheel 12 is rotatably connected inside the fan shroud 10. A drive component 13 is installed on the axis of the fan wheel 12. The other end of the fan shroud 10 is connected to a connecting pipe 14. The end of the connecting pipe 14 is connected to a connecting pipe 15 that is connected to the annular pipe 7, which facilitates the cooling of the casting.

[0028] Please see Figure 3 and Figure 4 The driving component 13 shown in the figure includes a fixed frame 17 fixed inside the base 4. A motor 16 is fixedly connected to the fixed frame 17. A drive shaft 18 is fixedly connected to the output end of the motor 16. The drive shaft 18 extends into the inside of the wind shroud 10 and is rotatably connected to the wind shroud 10. A rotating frame 19 fixedly connected to the wind wheel 12 is fixedly connected to the drive shaft 18 to facilitate driving the wind wheel 12 to rotate.

[0029] Please see Figure 3 and Figure 5 The striking assembly 9 shown in the figure includes multiple striking rods 20 that are in contact with the lower mold plate. The striking rods 20 are slidably connected to the base 4, and the bottom end of the striking rods 20 is fixedly connected to a connecting plate 22. An elastic element 21 is provided on the outer side of the striking rods 20, and a reciprocating element 23 is installed at the bottom end of the connecting plate 22 to facilitate striking the lower mold 5 so that the casting is separated from the lower mold 5.

[0030] Please see Figure 3 and Figure 5The reciprocating component 23 shown in the figure includes an incomplete gear 24 fixedly connected to the drive shaft 18. The outer side of the incomplete gear 24 is meshed with a rack 25 fixedly connected to the connecting plate 22, which facilitates cooperation with the elastic component 21 to allow the striking rod 20 to move up and down to strike the lower mold 5.

[0031] Please see Figure 5 and Figure 6 The elastic element 21 shown in the figure includes a fixing plate 26 fixedly connected to the striking rod 20. A tension spring 27 is fixedly connected to the fixing plate 26. The end of the tension spring 27 is fixedly connected to a connecting plate 28 fixedly connected to the base 4, which facilitates the reset of the striking rod 20 and thus facilitates the striking of the lower mold 5.

[0032] Please see Figure 5 The end of the striking rod 20 shown in the figure is provided with a rubber pad 29 to prevent rigid compression from damaging the lower mold 5.

[0033] Please see Figure 1 and Figure 2 The base 4 shown in the figure has heat dissipation holes 30, and support legs 31 are installed at the bottom corners of the base 4. The design of the heat dissipation holes 30 facilitates heat dissipation for the motor 16, and the setting of support legs 31 helps to improve the stability of the device.

[0034] During implementation, after the casting is formed, the upper mold 3 moves upward away from the lower mold 5. At this time, the control motor 16 starts, and the drive shaft 18 rotates through the action of the motor 16. The rotation of the drive shaft 18 causes the impeller 12 to rotate. During the rotation of the impeller 12, wind force will be generated inside the connecting pipe 14. The wind force enters the connecting pipe 15 through the connecting pipe 14, and then enters the annular pipe 7 through the connecting pipe 15. Finally, it is blown out through the blowing pipe 8. In this scheme, the blowing pipe 8 is inclined towards the lower mold 5, so that the air blown out by the blowing pipe 8 can cool down the casting in the lower mold 5 and accelerate the cooling of the casting.

[0035] During the rotation of the drive shaft 18, the drive shaft 18 will drive the incomplete gear 24 to rotate. The rotation of the incomplete gear 24 causes the rack 25 to move. The movement of the rack 25 causes the connecting plate 22 to move. The movement of the connecting plate 22 causes the striking rod 20 to move. During the movement of the striking rod, the tension spring 27 will be stretched. After the incomplete gear 24 disengages from the rack 25, the tension spring 27 causes the connecting plate 22 to drive the striking rod 20 to reset and strike the lower mold 5. After the incomplete gear 24 engages with the rack 25 again, it will drive the striking rod 20 to move down again. Through the above reciprocating motion, the lower mold 5 is struck, causing the casting to separate from the lower mold 5.
