Description

Technical Field

[0001] The utility model relates to the technical field of die casting, in particular to an aluminum fluid die casting mold. Background Art

[0002] In the traditional aluminum die casting forming process, the molten aluminum is heated to about 720°C, and the molten aluminum is pushed into the mold cavity by the injection force of the die casting machine screw. During the injection process of the molten aluminum, the farther the range of the molten aluminum, the worse the fluidity, and the smaller the injection force, which will cause defects:

[0003] 1. The feeding port needs to have a feeding pad;

[0004] 2. The thickness of the product cannot be less than 0.5 mm or greater than 10 mm, and the shape of the product cannot be too long;

[0005] 3. Due to the low density on the surface of the product, it will appear rough, and the flash on the mold joint line is serious;

[0006] 4. The energy consumption of the aluminum die casting machine is large, and the daily output is low.

[0007] Therefore, improvements need to be made to the above problems. Summary of the Invention

[0008] Aiming at the defects in the prior art such as the need for a feeding pad, large size limitations, roughness and serious flash, large energy consumption and low daily output, the utility model provides a new aluminum fluid die casting mold.

[0009] In order to solve the above technical problems, the utility model is realized through the following technical solutions:

[0010] An aluminum fluid die casting mold includes a punch assembly, a die assembly, and an automatic ladle. The punch assembly cooperates with the die assembly, and the automatic ladle cooperates with the die assembly.

[0011] The punch assembly is used for downward die casting and cooperates with the die assembly for mold closing. The die assembly is used for carrying molten aluminum and cooperating with die casting. The automatic ladle is used for accurately and quantitatively adding molten aluminum to the die assembly.

[0012] Through the above design, the die casting product of the utility model has a bright surface, high density, no flash, and small size limitations, no need for a feeding pad, lower energy consumption, and higher daily output.

[0013] Preferably, in the above-mentioned aluminum fluid die casting mold, the die assembly is provided with a die part, and an aluminum fluid area is arranged in the die part.

[0014] The aluminum fluid area provided inside the female die part allows the molten aluminum to flow and form within a controlled area, thereby ensuring the geometric shape and dimensional accuracy of the product and reducing material waste. The design of the female die part helps to ensure that the injection volume and flow path of the molten aluminum are consistent during each die-casting process, thus improving the consistency of the product.

[0015] Preferably, for the above-mentioned aluminum fluid die-casting mold, a bottom plate is provided at the bottom of the female die part. The bottom plate cooperates with the aluminum fluid area, and a strong magnetic ring is provided on the lower side of the bottom plate. The strong magnetic ring cooperates with the bottom plate.

[0016] The bottom plate is used to be inlaid at the bottom of the product. The strong magnetic ring is used to hold the bottom plate and prevent the molten aluminum from pouring in. The strong magnetic ring provides a strong and reliable fixing method to ensure that the bottom plate does not move or shift during the die-casting process.

[0017] Preferably, for the above-mentioned aluminum fluid die-casting mold, the female die assembly is further provided with a lower cylinder, and the lower cylinder cooperates with the bottom plate.

[0018] The lower cylinder is used to jack up the die-cast product after die-casting to assist the demolding process of the bottom plate, making it easier to take out the die-cast finished product from the mold. The presence of the lower cylinder provides additional support for the bottom plate and ensures the stability of the bottom plate during the die-casting process.

[0019] Preferably, for the above-mentioned aluminum fluid die-casting mold, the female die assembly is further provided with a workbench, a work panel is provided on the workbench, and the female die part is connected to the work panel.

[0020] The setting of the workbench and the work panel provides a stable platform, enabling the female die part to be firmly connected, thereby improving the overall stability of the mold. The work panel provides a convenient working area for the operator, facilitating the installation, adjustment, and maintenance of the mold.

[0021] Preferably, for the above-mentioned aluminum fluid die-casting mold, the automatic ladle includes an automatic manipulator and a quantitative ladle part. The automatic manipulator is connected to the quantitative ladle part, and the quantitative ladle part cooperates with the female die assembly.

[0022] Through the cooperation of the automatic manipulator and the quantitative ladle part, the automation of the molten aluminum injection is achieved. The quantitative ladle part can precisely control the amount of molten aluminum injected each time, thereby ensuring the consistency of the product quality and reducing waste. The automated molten aluminum injection process can significantly reduce the production cycle time and improve the overall production efficiency. The automated operation reduces the possibility of human operation errors and improves the reliability of the production process.

[0023] Preferably, for the above-mentioned aluminum fluid die-casting mold, the male die assembly is provided with an extrusion head, and the extrusion head cooperates with the female die assembly.

[0024] The cooperation between the extrusion head and the die cavity assembly ensures the precise forming of molten aluminum during the die-casting process, improving the geometric accuracy of the product. The design of the extrusion head helps reduce product defects such as air bubbles, shrinkage cavities, warping, and cracks, thereby improving product quality. The design of the extrusion head can disperse the pressure exerted on the die during use and extend the service life of the die.

[0025] Preferably, for the above-mentioned aluminum fluid die-casting mold, the punch assembly is further provided with an upper cylinder, and the upper cylinder cooperates with the extrusion head.

[0026] The upper cylinder provides pressure for the extrusion head, which helps to more precisely control the pressure during the die-casting process. The setting of the upper cylinder helps to ensure the precise cooperation between the extrusion head and the die cavity assembly, thereby improving the die-closing accuracy. The upper cylinder can quickly respond to pressure changes, shorten the cycle time of die-closing and separation, and improve production efficiency.

[0027] Preferably, for the above-mentioned aluminum fluid die-casting mold, it further includes a bracket. The upper cylinder is fixed on the bracket. The punch assembly is further provided with a downward moving cross plate. The extrusion head is connected to the lower side of the downward moving cross plate, and the downward moving cross plate is slidably connected to the bracket.

[0028] The bracket provides a stable fixing point for the upper cylinder and the punch assembly, which helps to maintain the stability of the overall mold. The design of the slidable connection between the downward moving cross plate and the bracket can accelerate the die-closing and separation speeds of the mold and improve production efficiency. The design of the bracket can be compatible with automated equipment to achieve an automated die-casting process.

[0029] Preferably, the die-casting process of the above-mentioned aluminum fluid die-casting mold includes the following steps:

[0030] S1: Take a negative film and place it at the bottom of the die cavity part of the die cavity assembly. After the strong magnetic ring on the lower side of the negative film is energized, it sucks the negative film. The quantitative spoon part of the automatic ladle pours 600°C - 640°C molten aluminum into the aluminum fluid area of the die cavity part;

[0031] S2: The extrusion head of the punch assembly moves downward to close the mold with the die cavity part. After closing the mold, wait for 3 to 4 seconds, and then extrude to the limit with a pressure of 400 Pa;

[0032] S3: The extrusion head returns to its original position, the strong magnetic ring is powered off, and the lower cylinder of the die cavity assembly jacks up from the position of the negative film to obtain the die-cast product.

[0033] Step S1 is used for injecting molten aluminum. A strong magnetic ring is used to hold the bottom plate, ensuring the precise positioning of the bottom plate in the concave die part, thereby improving the dimensional accuracy of the die-cast product. The quantitative spoon part of the automatic spoon realizes the automation of molten aluminum injection, reduces manual operation, and improves production efficiency. The temperature range of the molten aluminum is reduced while ensuring the fluidity of the molten aluminum and the die-casting quality.

[0034] Step S2 is used for die-casting. After the mold is closed, wait for 3 to 4 seconds to allow the molten aluminum to flow and partially cool in the concave die part, which helps the mold to be better filled and reduces internal defects. Using a pressure of 400 Pa for extrusion helps to improve the material density of the die-cast product, thereby achieving a product without burrs, honeycombs, and with a bright surface.

[0035] Step S3 is used for taking out the product. The action of the lower cylinder lifting from the position of the bottom plate helps to achieve rapid demolding of the product and improve production efficiency. Precise control of the demolding process helps to maintain the integrity of the product and avoid product defects caused by improper demolding.

[0036] The utility model is more energy-saving and efficient. The temperature of the molten aluminum is reduced from about 720 °C to about 620 °C, with lower energy consumption. There is no need for a feeding ladle, and the daily output is increased from the traditional 800 molds per shift to 2000 molds per shift.

[0037] The product of the utility model has a bright surface, no burrs, and does not require manual surface polishing.

[0038] The product of the utility model has little limitation on thickness and shape. The thickness can be less than 0.5 mm or greater than 10 mm, and the shape can be extra-long, as long as it can be installed in the die-casting mold.

[0039] The bottom covering of the utility model, that is, the installation of the bottom plate, is combined with the die-casting process, reducing the bottom covering cost and improving production efficiency. The adhesion of the bottom plate is higher, and the thermal conductivity of the bottom of the product aluminum pot is better.

[0040] The strong magnetic ring of the utility model holds the bottom plate to prevent the molten aluminum from pouring in and ensures the product quality. Brief Description of the Drawings
