Description

Technical Field

[0001] The utility model relates to the technical field of automobile structural part production, in particular to a rapid die-changing device for extrusion casting equipment of automobile structural parts. Background Art

[0002] Squeeze casting, also known as liquid die forging, involves pouring molten or semi-solid metal into a mold and then applying high mechanical pressure to form, crystallize, and solidify it, resulting in a casting. During the squeeze casting process, the molten metal crystallizes and shrinks under the action of external mechanical forces, accompanied by a small amount of plastic deformation, resulting in a dense casting structure and refined grains. Squeeze casting technology can produce high-performance aluminum alloy castings, replacing traditional steel materials, achieving lightweight vehicles and reducing fuel consumption and emissions. With the development of new energy vehicles and the need for lightweight vehicles, the application of advanced squeeze casting technology in automotive structural components will become increasingly widespread.

[0003] Extrusion casting equipment requires frequent mold changes during operation. Because existing molds are designed for single use, operators must remove and then replace the mold, which reduces mold change time and casting efficiency. Therefore, this utility model proposes a rapid mold change device for extrusion casting equipment for automotive structural parts to address the shortcomings of the existing technology.

[0019] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0020] according to Figure 1-5As shown, this embodiment proposes a quick mold changing device for extrusion casting equipment of automobile structural parts, including an extrusion casting stand 1, a mold storage rack 2 and a mold positioning mechanism 3. A through slot 4 is provided on the top of the extrusion casting stand 1, a mold storage rack 2 is provided on one side of the through slot 4, and a mounting plate 5 is provided on the other side of the through slot 4. The mounting plate 5 is rotatably connected to the extrusion casting stand 1 through a rotating shaft. A lifting mechanism is installed on the side wall of the extrusion casting stand 1, and the mold storage rack 2 is connected to the lifting mechanism. An L-shaped mounting bracket 6 is provided on the outer wall of the extrusion casting stand 1 on one side of the through slot 4, and a pushing cylinder 7 is provided on the L-shaped mounting bracket 6. A pushing plate 8 is provided inside the through slot 4, and the output end of the pushing cylinder 7 extends into the through slot 4 and is connected to the pushing plate 8. The mold positioning mechanism 3 is symmetrically provided on the front and rear side walls of the extrusion casting stand 1 at the position of the mounting plate 5. The front and rear side walls of the extrusion casting stand 1 are provided with through holes adapted to the position of the mold positioning mechanism 3, and the side walls of the mounting plate 5 are provided with positioning holes 9 adapted to the through holes.

[0021] When the extrusion casting equipment of automobile structural parts of the present invention is used with a quick mold changing device, the mold is installed on the mounting plate 5 and is connected to the extrusion casting stand 1 in a fixed position through the mold positioning mechanism 3. The mold storage rack 2 is used to store multiple molds waiting to be replaced. When the mold on the mounting plate 5 needs to be replaced, the mold positioning mechanism 3 is first released to limit the position of the mold and the mounting plate 5, so that the mounting plate 5 can be flipped through the rotating shaft. After the mounting plate 5 is flipped, the mold on it is flipped over and replaced. At this time, the mounting plate 5 is controlled to reset again, and then the pushing cylinder 7 is controlled to move so that the pushing plate 8 pushes the mold at the corresponding position on the mold storage rack 2 onto the mounting plate 5 (the mold of the present invention is specified to be a mold with a fixing hole on the side wall, and the fixed fixing hole is adapted to the positioning hole 9). Then the mold positioning mechanism 3 connects and fixes the mounting plate 5, the mold and the extrusion casting stand 1 together.

[0022] The mold storage rack 2 includes a support plate 201 and a vertical plate 202. The support plates 201 are provided in multiple groups. The vertical plates 202 are provided on the front and rear sides of the tops of the support plates 201 in each group. The bottom of the upper support plate 201 is connected to the top of the vertical plate 202. The vertical plates 202 guide the movement of the mold when the push plate 8 pushes the mold to move, ensuring that the mold is correctly pushed onto the mounting plate 5.

[0023] The lifting mechanism includes an upper fixed plate 10, a lower fixed plate 11, and a lifting cylinder 12. The upper fixed plate 10 is provided on the front and rear side walls of the squeeze casting platform 1 at the location of the mold storage rack 2, and the lower fixed plate 11 is provided on the front and rear side walls of the bottom group of support plates 201. The upper fixed plate 10 is provided with a lifting cylinder 12, and the output end of the lifting cylinder 12 is connected to the top of the lower fixed plate 11. The mold storage rack 2 can be moved and controlled by the lifting mechanism. Specifically, the mold storage rack 2 can be raised and lowered by controlling the movement of the lifting cylinder 12, so that different support plates 201 are at the same level as the mounting plate 5.

[0024] A drive motor 13 is mounted on the front side wall of the squeeze casting stand 1, and the rotating shaft is driven to rotate by the drive motor 13. When the drive motor 13 is started, the rotating shaft can be controlled to rotate, and the rotating shaft rotation drives the mounting plate 5 to flip.

[0025] The mold positioning mechanism 3 comprises a bracket 301 and a positioning cylinder 302. Brackets 301 are symmetrically positioned on the front and rear sidewalls of the extrusion casting platform 1. Positioning cylinders 302 are mounted on these brackets 301. The output end of each positioning cylinder 302 matches the position and diameter of the through hole and positioning hole 9. By controlling the extension of the positioning cylinder output end, it can be inserted into the positioning hole 9 and the fixing hole on the mold, thereby securing the mold, mounting plate, and extrusion casting platform 1 together.

[0026] The extrusion casting stand 1 includes a platform 101 and support bases 102. The platform 101 is provided with support bases 102 at the bottom. Three sets of support bases 102 are provided. A support plate 14 slides between two sets of support bases 102 below the mounting plate 5. The support plate 14 can be used to catch a replaced mold that falls from the mounting plate 5.

[0027] The utility model provides a mold storage rack 2 driven by a lifting mechanism in the through slot of the extrusion casting stand 1, provides a mounting plate 5 installed by a rotating shaft, provides a pushing structure composed of an L-shaped mounting rack 6, a pushing cylinder 7 and a pushing plate 8, and provides a mold positioning mechanism 3. The mold storage rack 2 can be used to store molds to be replaced. The pushing structure composed of the L-shaped mounting rack 6, the pushing cylinder 7 and the pushing plate 8 can push the mold storage rack 2 onto the mounting plate 5. The mold located on the mounting plate 5 can be positioned by the mold positioning mechanism 3, and the mold located on the mounting plate 5 waiting to be replaced can be turned over by the mounting plate 5 to be removed from the mounting plate 5. The above-mentioned combination can realize rapid replacement of the mold, and the replacement process has a high degree of automation. Human labor does not need to touch the high-temperature mold, which can avoid burns.
