Tilt Casting Mold Continuous Pouring Eliminates Turbulence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tilt casting methods for light metal components, such as aluminum alloys, face challenges in preventing flow turbulences and efficiently filling the mold cavity during tilting, often requiring intermediate melt collection containers that can lead to turbulence and inefficiencies.
Innovation Solution
The method involves continuous pouring of the light-metal melt directly into the casting run of the tilt casting mold at the beginning and during tilting, with a casting ladle or scoop tracking the mold, eliminating the need for intermediate melt collection containers and guiding the melt through a bottleneck to minimize turbulence, and using a tilt casting device without a transverse run or melt holding container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If intermediate melt collection containers (transverse run, melt holding container) are used to fill the mold cavity during tilting, then the mold can be filled with melt, but flow turbulences occur and the process becomes less efficient
Solution Approach 1:
The invention removes the intermediate melt collection container (transverse run, melt holding container) from the casting system. By directly pouring melt from the ladle into the mold cavity during tilting, the patent eliminates the source of turbulence associated with intermediate containers while maintaining continuous filling capability, thus resolving the contradiction between flow quality and filling efficiency
Solution Approach 2:
The invention implements continuous pouring of melt throughout the entire tilting process. The ladle follows the tilting mold continuously, ensuring uninterrupted melt flow directly into the mold cavity. This continuous action eliminates the need for intermediate containers and maintains both high flow quality and filling efficiency simultaneously
2Manufacturing precision
If melt is poured directly into the mold cavity during tilting without intermediate containers, then flow turbulences are reduced, but it requires precise tracking of the mold by the casting ladle
Solution Approach 1:
The invention introduces a guiding device as an intermediary between the casting ladle and the tilting mold. This guiding device automatically tracks the mold's tilting movement and guides the ladle accordingly, eliminating the need for manual precise tracking while maintaining direct pouring into the mold cavity, thus preserving flow quality while improving ease of operation
Solution Approach 2:
The guiding device is designed to automatically follow the mold's tilting motion without requiring external control input. The system self-adjusts the ladle position to match the mold position throughout the tilting process, making the operation straightforward while maintaining precise direct pouring

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach ensures a smooth, turbulence-reduced flow of the melt into the mold cavity, enabling the production of high-quality light metal components by avoiding the formation of casting pools and ensuring efficient filling without interruptions, thereby improving the tilt casting process.
Implementation Method 1
a die or casting mold is rotated about a tilt axis by up to 90°, while the melt flows into the die. By means of this measure, the die can be filled with the metal melt in particularly advantageous manner, without flow turbulences. A significant advantage of tilt casting, which is frequently mentioned in the literature, consists in that any splashed metal that might occur during gravity die casting can be prevented by guiding the metal melt along a wall of the casting mold.
Implementation Method 2
the light-metal melt is continuously poured directly into the casting run of the tilt casting mold, which forms the sprue of the component, at the beginning of and during the tilting movement of the tilt casting mold, using a casting ladle or a casting scoop, and flows through the casting run into the mold cavity of the tilt casting mold from the beginning, wherein the casting scoop or the casting ladle continuously tracks the casting mold during the tilting movement.
