Description

Technical Field

[0001] This utility model relates to an aluminum die-casting cylinder, and more particularly to an aluminum die-casting cylinder with adjustable filling degree. Background Technology

[0002] Die casting is a highly efficient metal casting process that involves injecting molten metal under high pressure into the cavity of a precision mold, where it rapidly cools and solidifies to produce metal parts with complex shapes and high precision. In this process, the die casting cylinder, as a key component of the die casting machine, plays a crucial role in storing and transporting the molten metal. Traditional die casting cylinders have a fixed structure, typically consisting of a cylinder body, liner, inlet window, outlet, sealing device, and other auxiliary components. The degree to which the molten aluminum fills the cylinder directly affects the quality of the die-cast product, and this degree of filling is limited by the cylinder's length, diameter, the position of the inlet window, and the positions of the scoop and punch.

[0003] In existing technologies, the design of die-casting cylinders has some limitations. For example, patents CN203304522U ("A Lubrication Device for a Die-casting Cylinder"), CN205587627U ("A Structure for Improving Air Entrainment in a Cylinder in a Mold"), and CN2144429U ("An Oil-cooled Integral Cylinder for a Die-casting Mold") all disclose cylinder structures. In these cylinders, because the position of the feed window is fixed, the position of the punch is limited by the scoop, causing the die-casting punch to only work behind the feed window, making it impossible to adjust the filling degree of the molten aluminum. This limits the flexibility of the die-casting process and the consistency of the products. Utility Model Content

[0023] like Figure 1-2As shown, this embodiment provides an aluminum die-casting cylinder with adjustable filling degree, including a cylinder body 1 with a compression chamber and a punch 2 connected to a piston rod 3.

[0024] like Figure 1-2 As shown, the tail end of the material cylinder body 1 is open and the punch 2 extends into the self-compression chamber. An adjustable feeding area 4 is provided on the upper side wall of the end of the material cylinder body 1 near the punch 2. The adjustable feeding area 4 includes a through hole with a rectangular or quasi-rectangular outline and a stop block 42 located in front of the through hole.

[0025] like Figure 1-2 As shown, when the stop block 42 is located inside the through hole, the rear section of the through hole forms a first feed window m. The scoop is positioned above the first feed window m and enters the compression chamber to collect material. When the stop block 42 is removed from the through hole, the through hole forms a second feed window n, the scoop moves forward from the front section of the second feed window n, and the punch 2 moves forward to the side of the through hole.

[0026] like Figure 3-4 As shown, when die-casting defects such as cold material and white spots appear in the product, the filling degree of the die-casting cylinder can be increased to improve the die-casting defects. At this time, the stop block 42 can be removed, so that the setting position of the scoop is moved forward, and the die-casting punch 2 is moved forward. After these steps are completed, the filling degree of the aluminum liquid in the cylinder will be increased accordingly. Without replacing the die-casting cylinder, the increased filling degree of the aluminum liquid has a significant improvement on defects such as cold material and white spots in the product, greatly improving the efficiency of die-casting and reducing the replacement time of the die-casting equipment.

[0027] like Figure 1-4 As shown, the walls of the through holes are all inclined from the outside inwards towards the center. The stop block 42 has an inclined front wall and inclined side walls that cooperate with the inner front wall and the inner side walls of the through holes. The stop block 42 is engaged in the through hole. The configuration of the inclined walls ensures the contact area between the two and also restricts the installation position of the stop block 42, making the positional fit between the two more precise.

[0028] like Figure 2 As shown, the front end of the material cylinder body 1 is provided with a sprue sleeve 6, and the outer periphery of the material cylinder body 1 is provided with a flange ring 7. The punch 2 is a circular punch 2, and the diameter of the punch 2 is the same as the width of the through hole.

[0029] like Figure 2 As shown, the material cylinder body 1 is composed of a front material distribution cylinder 11 and a rear material distribution cylinder 12 connected in the length direction. The front end of the front material distribution cylinder 11 is provided with a sprue sleeve 6, and the outer periphery of the front material distribution cylinder 11 is provided with a flange ring 7.

[0030] The above describes an adjustable-filling-degree aluminum die-casting cylinder provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand this utility model and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from its principle, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
