Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy brackets, in particular to a mold for forming a high-strength aluminum alloy bracket. Background Art

[0002] A casting mold is a process that creates a part's structural shape by pre-forming it with other easily moldable materials. The mold is then placed in a sand mold, creating a cavity with the same dimensions as the part. A fluid liquid is then poured into this cavity, which, after cooling and solidifying, forms a part with the exact same shape and structure as the mold. Casting molds are a crucial part in the casting process.

[0003] Existing aluminum alloy brackets are widely used in aerospace, automotive, and electronic equipment due to their lightweight, high strength, and excellent corrosion resistance. However, the production of aluminum alloy brackets still presents several technical challenges. Traditional aluminum alloys are prone to thermal deformation at high temperatures, and casting molds often experience a loss of precision after prolonged operation, resulting in uneven wall thickness and loose structure in the casting, making it difficult to meet the requirements for high-strength mechanical properties. Therefore, a mold for forming high-strength aluminum alloy brackets has been proposed. Utility Model Content

[0004] The purpose of the present invention is to provide a high-strength aluminum alloy bracket forming die to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a high-strength aluminum alloy bracket forming mold, comprising a lower mold and an upper mold,

[0006] Two forming cavities are provided inside the lower mold and the upper mold;

[0007] An aluminum alloy bracket body is cast inside the molding cavity;

[0008] A gate connected to the molding cavity is installed on one side of the lower mold;

[0009] Sliders are connected to both sides of the lower mold and the upper mold;

[0010] The other two sides of the lower mold are provided with first limiting grooves, and the other two sides of the upper mold are provided with second limiting grooves;

[0011] Locking blocks are provided on both sides of the lower mold and the upper mold;

[0012] A filter component is provided on one side of the gate.

[0013] Preferably, the filter assembly includes a connecting pipe, one end of which is integrally formed with a hexagonal connector, and an inner wall of the connecting pipe is provided with a filter screen.

[0014] Preferably, the outer side of the connecting pipe is provided with an external thread, and the inner wall of the gate is provided with an internal thread connected to the external thread.

[0015] Preferably, a first limiting rib and a second limiting rib are respectively provided on one side of the locking block, and the first limiting rib and the second limiting rib are distributed up and down.

[0016] Preferably, when the locking block is attached to one side of the lower mold and the upper mold, the first limiting rib and the second limiting rib are respectively inserted into the inner sides of the first limiting groove and the second limiting groove.

[0017] Preferably, the slider is located on one side of the molding cavity.

[0018] Compared with the prior art, the above technical solution adopted by the present invention has the following technical effects:

[0019] 1. Filtering the metal liquid through the filter screen inside the gate can effectively remove impurities in the metal liquid, which can not only improve the quality and purity of the casting products, but also extend the service life of the mold and reduce mold damage and maintenance costs caused by impurities.

[0020] 2. The driving mechanism drives the slider to contact both sides of the lower mold and the upper mold to ensure that the molding cavity accurately forms the aluminum alloy bracket body. The first limiting rib and the second limiting rib on the outside of the locking block are inserted into the inside of the first limiting groove and the second limiting groove, which effectively reduces the impact of thermal deformation of the casting mold, thereby solving the problem of aluminum leakage that may occur during the production process, and helps to ensure that the wall thickness of the casting is uniform and the structure is dense, meeting the requirements of high-strength mechanical properties.

[0021] 3. By adopting the integrated low-pressure casting of the lower mold and the upper mold, the molding cavity forms two aluminum alloy bracket bodies at one time, which significantly improves the production efficiency and can effectively prevent the aluminum alloy bracket body from being deformed during demolding and ejection, further ensuring product quality, reducing the scrap rate, and thus reducing production costs.

[0033] Example

[0034] See also Figure 1-7The utility model provides a technical solution: a mold for forming a high-strength aluminum alloy bracket, including a lower mold 2 and an upper mold 8. The lower mold 2 and the upper mold 8 are provided with two molding cavities inside, and the aluminum alloy bracket body 1 is cast inside the molding cavity; a gate 10 connected to the molding cavity is installed on one side of the lower mold 2, and a driving mechanism drives one end of a slider 7 to contact both sides of the lower mold 2 and the upper mold 8. At this time, under the action of the slider 7, the lower mold 2 and the upper mold 8, the molding cavity forms the aluminum alloy bracket body 1;

[0035] Slide blocks 7 are connected to both sides of the lower mold 2 and the upper mold 8; first limiting grooves 3 are provided on the other two sides of the lower mold 2, and second limiting grooves 11 are provided on the other two sides of the upper mold 8; locking blocks 4 are provided on both sides of the lower mold 2 and the upper mold 8, and the slide blocks 7 and the locking blocks 4 are connected to the driving mechanism of the operating table. The driving mechanism can be a hydraulic cylinder or a pneumatic cylinder;

[0036] A filter assembly 9 is provided on one side of the gate 10 .

[0037] In order to improve the casting quality of the aluminum alloy bracket body 1, a filter assembly 9 is provided. The filter assembly 9 includes a connecting pipe 91. A hexagonal connector 92 is integrally formed at one end of the connecting pipe 91. A sealing ring (not shown in the figure) can be installed on one side of the hexagonal connector 92. The sealing ring is used to seal the connection between the connecting pipe 91 and the gate 10. A filter screen 93 is installed on the inner wall of the connecting pipe 91. An external thread is provided on the outer side of the connecting pipe 91, and an internal thread connected to the external thread is provided on the inner wall of the gate 10. The metal liquid enters the inner side of the molding cavity through the gate 10. When the metal liquid passes through the filter screen 93 threadedly connected to the inner side of the gate 10, the filter screen 93 filters impurities in the metal liquid. Before the metal liquid enters the molding cavity, the metal liquid is filtered by the filter screen 93 on the inner side of the gate 10.

[0038] A first limiting rib 5 and a second limiting rib 6 are respectively provided on one side of the locking block 4, and the first limiting rib 5 and the second limiting rib 6 are distributed up and down. When the locking block 4 is attached to one side of the lower mold 2 and the upper mold 8, the first limiting rib 5 and the second limiting rib 6 are respectively inserted into the inner sides of the first limiting groove 3 and the second limiting groove 11, and the first limiting rib 5 and the second limiting rib 6 on the outside of the locking block 4 are inserted into the inner sides of the first limiting groove 3 and the second limiting groove 11, which reduces the influence of thermal deformation of the casting mold and solves the problem of aluminum leakage in the production process, so that the wall thickness of the low-pressure process casting is uniform and dense. The slider 7 is located on one side of the molding cavity, and the lower mold 2 and the upper mold 8 are integrated into low-pressure casting. The molding cavity forms two aluminum alloy bracket bodies 1 at one time to prevent the aluminum alloy bracket body 1 from being ejected and deformed.

[0039] Working principle: First, install the lower mold 2 and the upper mold 8 on the operating table surface of the die-casting machine, and at the same time connect the slider 7 and the locking block 4 to the driving mechanism of the operating table. The driving mechanism can be a hydraulic cylinder or an air cylinder. At this time, the cast metal liquid enters the inner side of the molding cavity through the gate 10. When the metal liquid passes through the filter screen 93 threadedly connected to the inner side of the gate 10, the filter screen 93 filters the impurities in the metal liquid. Before the metal liquid enters the molding cavity, the metal liquid is filtered through the filter screen 93 on the inner side of the gate 10, which can effectively remove impurities in the metal liquid, which can not only improve the quality and purity of the cast products, but also extend the service life of the mold and reduce mold damage and maintenance costs caused by impurities.

[0040] When a large amount of impurities are clogged on the surface of the filter screen 93 , you only need to use a wrench to rotate the hexagonal connector 92 to drive the connecting pipe 91 away from the inside of the gate 10 . At this time, take a new filter assembly 9 and install it inside the gate 10 .

[0041] At this time, the metal liquid enters the inner side of the molding cavity, and the driving mechanism drives one end of the slider 7 to contact the two sides of the lower mold 2 and the upper mold 8. At this time, under the action of the slider 7, the lower mold 2 and the upper mold 8, the molding cavity molds the aluminum alloy bracket body 1. During molding, the first limiting rib 5 and the second limiting rib 6 on the outside of the locking block 4 are inserted into the inside of the first limiting groove 3 and the second limiting groove 11, reducing the impact of thermal deformation of the casting mold, solving the problem of aluminum leakage during the production process, and making the low-pressure process castings have uniform wall thickness and good density, which can meet the requirements of high-strength mechanical properties. At the same time, the lower mold 2 and the upper mold 8 are integrated into low-pressure casting, and the molding cavity molds two aluminum alloy bracket bodies 1 at a time to prevent the aluminum alloy bracket body 1 from being ejected and deformed, shortening the production cycle, improving production efficiency, and reducing production costs.

[0042] In summary, the driving mechanism drives the slider 7 to contact both sides of the lower mold 2 and the upper mold 8, ensuring that the molding cavity accurately molds the aluminum alloy bracket body 1, and the first limiting rib 5 and the second limiting rib 6 on the outside of the locking block 4 are inserted into the inside of the first limiting groove 3 and the second limiting groove 11, which effectively reduces the impact of thermal deformation of the casting mold, thereby solving the problem of aluminum leakage that may occur during the production process, and helps to ensure that the wall thickness of the casting is uniform and the structure is dense, meeting the requirements of high-strength mechanical properties.

[0043] By adopting the integrated low-pressure casting of the lower mold 2 and the upper mold 8, the molding cavity forms two aluminum alloy bracket bodies 1 at one time, which significantly improves the production efficiency and can effectively prevent the aluminum alloy bracket body 1 from being deformed during demolding and ejection, further ensuring product quality, reducing the scrap rate, and thus reducing production costs.
