Description

Technical Field

[0001] This utility model relates to the field of aluminum casting processing technology, specifically a stamping device for aluminum casting processing. Background Technology

[0002] Aluminum castings refer to metal products made by processing aluminum alloy materials through casting processes. Due to the excellent properties of aluminum alloys (such as low density, corrosion resistance, good thermal conductivity, and ease of processing) and the flexibility of casting processes, they are widely used in many fields.

[0003] In the current aluminum casting process, stamping machines are used. When stamping aluminum castings, traditional stamping machines place the aluminum castings on the inner wall of the mold and then control the hydraulic cylinder of the stamping machine to drive the stamping plate to descend until it contacts the mold, thereby completing the stamping of the aluminum castings. However, after stamping, the extrusion will cause the aluminum castings to fit tightly against the inner wall of the mold, which will affect the easy removal of the aluminum castings.

[0004] To address the problems mentioned above, those skilled in the art have proposed a stamping device for processing aluminum castings. Utility Model Content

[0005] The purpose of this invention is to provide a stamping device for processing aluminum castings, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A stamping device for processing aluminum castings includes a stamping base, brackets installed at the four corners of the stamping base, a top plate installed on the top of the brackets, and two sets of symmetrically distributed guide rods installed between the stamping base and the top plate. Each set of guide rods consists of two rods symmetrically distributed on the stamping base. A lifting frame is slidably mounted on the guide rods. An entry groove is opened in the middle of the lifting frame. A mold frame is installed at the bottom of the lifting frame, and the inner wall of the mold frame is aligned with the entry groove. A mold groove that mates with the mold frame is opened on the stamping base. A stamping assembly is provided on the top plate for stamping. Limiting assemblies are provided on both sides of the stamping base for limiting the entry of the lifting frame.

[0008] As a further embodiment of this utility model, the mold frame and the mold groove have the same thickness.

[0009] As a further improvement of this utility model: two symmetrically distributed first hydraulic cylinders are installed on the stamping base, and the top of the first hydraulic cylinders is connected to the end of the lifting frame.

[0010] As a further embodiment of this utility model: the stamping assembly includes a second hydraulic cylinder mounted on the top plate, a drive plate mounted on the bottom of the second hydraulic cylinder, the drive plate being slidably connected to the guide rod, a mounting seat mounted on the bottom of the drive plate, and a stamping plate matching the mold frame mounted on the bottom of the mounting seat.

[0011] As a further improvement of this utility model, the thickness of the mounting base is greater than the thickness of the mold groove.

[0012] As a further improvement of this utility model: the limiting component includes a third hydraulic cylinder installed on both sides of the stamping seat, the third hydraulic cylinder is fixedly connected to the limiting block, and the limiting block is provided with a slot that matches the two ends of the lifting frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model moves the lifting frame along the guide rod to a position that fits against the stamping seat. At this time, the mold frame at the bottom of the lifting frame will be inserted into the mold groove and fit against the inner wall of the mold groove. At this time, the aluminum casting can be placed in the mold frame, and then the stamping assembly will stamp the aluminum casting in the mold frame. After the stamping is completed, the lifting frame is driven to rise along the guide rod, so that the mold frame also rises synchronously. Due to the pressure applied to the aluminum casting by the stamping assembly, the stamped aluminum casting will not rise synchronously during the rise of the mold frame until the mold frame separates from the aluminum casting. Then the stamping assembly can rise. At this time, since there is a gap between the stamped aluminum casting and the inner wall of the mold groove, it is convenient to remove it with tools, thus improving the convenience of removing the aluminum casting.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] Please see Figures 1-3A stamping device for processing aluminum castings includes a stamping base 1, brackets 3 installed at the four corners of the stamping base 1, a top plate 4 installed on the top of the brackets 3, and two sets of symmetrically distributed guide rods 5 installed between the stamping base 1 and the top plate 4. Each set of guide rods 5 consists of two rods symmetrically distributed on the stamping base 1. A lifting frame 6 is slidably mounted on the guide rods 5. An entry groove 7 is opened in the middle of the lifting frame 6. A mold frame 8 is installed at the bottom of the lifting frame 6. The inner wall of the mold frame 8 is aligned with the entry groove 7. A mold groove 2 that mates with the mold frame 8 is opened on the stamping base 1. A stamping assembly is provided on the top plate 4 for stamping. Limiting assemblies are provided on both sides of the stamping base 1 for limiting the entry of the lifting frame 6.

[0020] By moving the lifting frame 6 along the guide rod 5 to a position where it fits against the stamping seat 1, the mold frame 8 at the bottom of the lifting frame 6 will be inserted into the mold groove 2 and fit against the inner wall of the mold groove 2. At this time, the aluminum casting can be placed in the mold frame 8, and then the stamping assembly will stamp the aluminum casting in the mold frame 8. After the stamping is completed, the lifting frame 6 is driven to rise along the guide rod 5, so that the mold frame 8 also rises synchronously. Due to the pressure applied to the aluminum casting by the stamping assembly, the stamped aluminum casting will not rise synchronously during the rise of the mold frame 8 until the mold frame 8 separates from the aluminum casting. Then the stamping assembly can rise. At this time, since there is a gap between the stamped aluminum casting and the inner wall of the mold groove 2, it is convenient to remove it with tools, thus improving the convenience of removing the aluminum casting.

[0021] In one embodiment, the mold frame 8 and the mold groove 2 have the same thickness.

[0022] Since the mold frame 8 and the mold groove 2 have the same thickness, and since the mold frame 8 and the mold groove 2 match each other, the mold frame 8 can be completely inserted into the mold groove 2, and the mold frame 8 fits against the inner wall of the mold groove 2. At this time, the lifting frame 6 will fit against the stamping seat 1, which makes it convenient for the limiting component to limit the lifting frame 6.

[0023] In one embodiment, two symmetrically distributed first hydraulic cylinders 9 are installed on the stamping base 1, and the top of the first hydraulic cylinders 9 is connected to the end of the lifting frame 6.

[0024] The lifting frame 6 is driven by the first hydraulic cylinder 9 to move up and down along the guide rod 5, thereby adjusting the height of the mold frame 8.

[0025] In one embodiment, the stamping assembly includes a second hydraulic cylinder 13 mounted on the top plate 4. A drive plate 10 is mounted on the bottom of the second hydraulic cylinder 13. The drive plate 10 is slidably connected to the guide rod 5. A mounting base 11 is mounted on the bottom of the drive plate 10. A stamping plate 12 matching the mold frame 8 is mounted on the bottom of the mounting base 11.

[0026] During stamping, the second hydraulic cylinder 13 is activated by the control unit of the stamping machine. The second hydraulic cylinder 13 drives the drive plate 10 to descend along the guide rod 5, thereby driving the mounting base 11 to descend, so that the mounting base 11 drives the stamping plate 12 to enter the mold frame 8 to stamp the aluminum casting.

[0027] In one embodiment, the thickness of the mounting base 11 is greater than the thickness of the mold groove 2.

[0028] Because the thickness of the mounting base 11 is greater than the thickness of the mold groove 2, the lifting frame 6 can rise along the guide rod 5 and separate from the aluminum casting when the stamping is completed.

[0029] In one embodiment, the limiting component includes a third hydraulic cylinder 14 installed on both sides of the stamping seat 1. The third hydraulic cylinder 14 is fixedly connected to the limiting block 15, and the limiting block 15 is provided with a slot 16 that matches both ends of the lifting frame 6.

[0030] When the mold frame 8 is fully inserted into the mold groove 2, the third hydraulic cylinder 14 is activated to drive the limit block 15 to move, so that the slot 16 of the limit plate fits with the end of the lifting frame 6, thereby limiting the lifting frame 6 and preventing the mold frame 8 from moving during the stamping process.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
