Automated Casting Carriage System for Rapid Mold Changeover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current casting processes, such as counter-pressure die casting and low-pressure die casting, are labor-intensive and have long changeover times, particularly when switching molds or furnaces, which hampers productivity and automation.
Innovation Solution
A method and system for casting under pressure that includes a plant with a hermetically sealable lower chamber for the furnace and an upper chamber for the mold, where the mold halves can be pivoted for easy access and treatment, and a rail system for fully automatic transfer of furnaces and molds, utilizing parallel valves for precise pressure control and a carriage system to significantly reduce changeover times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual handling and preparation of molds and furnaces is used, then labor flexibility is maintained, but changeover times are long (8 hours) and productivity is low
Solution Approach 1:
The system enables self-service through automated carriages that automatically transport molds and furnaces between positions without manual intervention. The carriage system with automated positioning and handling reduces changeover operations from requiring 8 hours of manual labor to completing the same tasks in approximately 15 minutes, significantly improving productivity while maintaining controlled complexity through standardized automated mechanisms
Solution Approach 2:
The system implements dynamic adaptability through movable mold halves that can be pivoted between horizontal and vertical positions, and through a carriage system that dynamically transports components between storage and working positions. This dynamic configuration allows the same automated system to handle multiple mold types and furnace configurations, reducing changeover time while maintaining flexibility
2Ease of operation
If molds are kept in horizontal position for casting, then casting process is simplified, but access to inner surface for treatment is difficult and labor-intensive
Solution Approach 1:
The mold halves are designed to be dynamically reconfigurable between horizontal and vertical positions. During the casting process, molds remain in the horizontal position for simplified operation. For maintenance and treatment operations, the molds can be pivoted to a vertical position, providing easy access to the inner surface without requiring workers to crawl between mold halves, thus reducing treatment time while maintaining operational simplicity
Solution Approach 2:
The system transitions the mold orientation from a two-dimensional horizontal plane to a three-dimensional vertical configuration during maintenance operations. This dimensional change allows workers to access the inner surface of the mold from the front in a standing position, eliminating the need to work in confined horizontal spaces and significantly reducing the time and effort required for mold treatment
3Productivity
If frequent mold and furnace changes are performed manually, then production flexibility is maintained, but labor intensity increases and productivity decreases
Solution Approach 1:
The automated carriage system performs self-service by automatically transporting molds and furnaces between storage and working positions without requiring manual handling. The system includes automated positioning mechanisms that align components precisely, reducing the need for operator intervention and enabling more frequent mold and furnace changes to be performed automatically, thereby increasing casting output per hour while reducing manual labor requirements
Solution Approach 2:
The system replaces manual mechanical handling with automated mechanical systems. Carriages equipped with positioning mechanisms automatically transport and position molds and furnaces, substituting human physical effort with automated mechanical action. This substitution enables more frequent changes to be performed in less time, increasing productivity while reducing the extent of manual automation required

Function Achieved in This Case
This approach increases automation, reduces changeover times from 8 hours to 15 minutes, enhances productivity, and improves control quality by allowing for efficient and time-saving maintenance and preparation of mold surfaces, while maintaining precise pressure regulation.
Implementation Method 1
the pressurization of the molten metal in the furnace to pump it up into the mold is achieved by a pressure differential, by slightly reducing the gas pressure in the mold. This creates an overpressure in the casting furnace, which is sufficient for the molten metal to rise into the mold.
Implementation Method 2
Such systems with a casting device, especially for casting under pressure generated by a gas phase
