Core Manufacturing Apparatus Parallel Linkage Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing core manufacturing apparatuses face productivity issues due to the need to uncouple and recouple the storage unit from the kneading vessel when transitioning between horizontal and vertical states, leading to inefficiencies in core sand distribution and packing.
Innovation Solution
A core manufacturing apparatus with a storage unit that remains coupled to the kneading vessel through a parallel linkage system, allowing it to turn with the vessel without uncoupling, ensuring continuous operation and accurate core sand feeding and weighing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the storage unit is uncoupled and recoupled when the kneading vessel transitions between horizontal and vertical states, then the storage unit can maintain proper positioning, but productivity decreases due to time loss from uncoupling and coupling actions
Solution Approach 1:
The storage unit is made dynamically adjustable through a support mechanism that allows it to change its orientation angle. The support includes a rotating table or similar mechanism that enables the storage unit to tilt and follow the kneading vessel's movement between horizontal and vertical states, maintaining proper positioning without uncoupling.
Solution Approach 2:
A support mechanism acts as an intermediary between the storage unit and the kneading vessel. This support includes a rotating table or positioning mechanism that mediates the transition, allowing the storage unit to maintain proper orientation relative to the kneading vessel during state changes without direct coupling or uncoupling actions.
2Device complexity
If the storage unit remains fixed in position while the kneading vessel turns, then the storage unit structure is simple, but it cannot maintain proper coupling posture during transition
Solution Approach 1:
The storage unit incorporates a dynamic support mechanism with adjustable orientation. The support allows the storage unit to rotate or tilt, changing its angle to match the kneading vessel's orientation during transitions between horizontal and vertical states, maintaining proper coupling throughout the movement.
3Device complexity
If the kneading vessel operates in horizontal state only, then the feed port positioning is simple, but core sand cannot be packed into far corners of the mold effectively
Solution Approach 1:
The kneading vessel is designed to dynamically change its orientation from horizontal to vertical state. This dynamic positioning allows the ejection port to be oriented vertically during ejection, enabling core sand to be packed into far corners of the mold effectively while maintaining simple feed port positioning in the horizontal state.

AI summary
Provided is a core manufacturing apparatus including: a storage unit configured to store core sand; a kneading vessel configured to be fed with the core sand; a kneading rod configured to knead the core sand; and a piston configured to eject the kneaded core sand. The kneading vessel is capable of transitioning between a horizontally lying state and a vertically standing state and configured to be fed with the core sand in the horizontally lying state. The piston is configured to eject and pack the core sand into a mold with the kneading vessel in the vertically standing state. The storage unit is turnably coupled to the kneading vessel and configured to remain coupled to the kneading vessel in the same posture while the kneading vessel turns.
