Description

[0001] MATERIAL INLET SLEEVE PART FOR HIGH-PRESSURE DIE CASTING MOLDS

[0002] Technical Field:

[0003] The invention relates to the sleeve part located in the material inlet section of high- pressure die casting molds.

[0004] This invention relates to a sleeve part for preventing the problem of material solidification during the production of lightweight products.

[0005] Prior Art:

[0006] High-pressure die casting is a casting method based on filling liquid metal into a metal mold under pressure, where solidification occurs under pressure. The material is transferred to the casting mold chamber through a component known as the sleeve part. The invention described in this specification relates to this sleeve part.

[0007] In the casting of lightweight parts (e.g., below 1 kg), the molten material loses heat and solidifies as it progresses along the sleeve. This not only negatively impacts casting performance but also adversely affects the reusability of the sleeve part. This situation is particularly observed in low-weight casting processes because the molten raw material progresses within the sleeve with a low wall thickness. The same issue is not encountered in the production of high-weight parts.

[0008] In the prior art, certain dyes are used to prevent the material, which progresses along the sleeve and pours into the mold chamber, from solidifying. These dyes reduce surface roughness, allowing the molten material to flow without sticking and solidifying. However, they do not provide a solution for low-weight molten materials. The main reason for this is the loss of heat by the molten material.

[0009] As a result, there is a need for a new sleeve part that overcomes the prior art and eliminates its disadvantages. Summary of the Invention:

[0010] The invention is a sleeve part that overcomes the prior art, eliminates its disadvantages, and additionally offers extra advantages.

[0011] The objective of the invention is to provide a sleeve part that ensures the molten material progresses into the mold chamber without solidifying and sticking.

[0012] The sleeve part of the invention comprises a resistor. With the resistor, the temperature of the sleeve part is raised to between 200-250°C. Thus, the liquid molten material reaches the chamber stably at the same temperature. The solidification problem during the transfer has been reduced by 90%. The stability of the temperature significantly contributes to obtaining good parts in terms of qualitative properties.

[0020] Description of the Invention:

[0021] In this detailed description, the sleeve part (10) of the invention is explained with examples solely for better understanding of the subject, without creating any limiting effect.

[0022] The sleeve part (10) mentioned in the invention is located in the material inlet section of the die casting mold. The sleeve part (10) is a U-shaped, thin-walled component. Since it is positioned at an angle, the molten material poured from its upper section progresses into the die casting mold chamber through the mouth (11 ) section at its lower end.

[0023] Here, when the molten material comes into contact with the inner surface of the sleeve part (10), it loses its heat, and solidification is observed. This issue becomes much more pronounced, especially during the die casting of lightweight parts. This is because, in lightweight parts, the casting melt flows through the sleeve part (10) with a thin wall, and in such cases, solidification in the contact areas obstructs the flow of the melt.

[0024] The solution in the invention involves heating the sleeve part (10) with a resistor (12). Although this heating is considered to be between 200-250°C, it may vary depending on the parameters of the casting process.

[0025] In the invention, the resistor (12) placed in any section of the sleeve part (10) heats the sleeve part (10). The resistor (12) can be located throughout the entire sleeve part (10) or in a section near the mouth (11 ). The design of the resistor (12) is such that it wraps around the sleeve part (10) from the outside and, like the sleeve part (10), has a U-shaped cross-section.

[0026] The sleeve part (10) mentioned in the invention is a component of the molten material dosing system used in high-pressure die casting processes. The use of a dosing system provides a significant advantage as it prevents the molten material from coming into contact with air. However, even in dosing systems, the problem of molten material solidification is encountered. The present invention comprises a resistor design that addresses this issue.
