Ejector Base Insert Plate Plug Screw Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mould container press systems face inefficiencies due to the time-consuming process of replacing worn-out ejector bases and insert plates, which are prone to rust and require labor-intensive retapping of screw threads, leading to prolonged downtime in brick production.
Innovation Solution
The introduction of a plug and screw connection for the insert plate on the ejector base, combined with a preassembled ejecting device that can be displaced through an opening in the mould container part, allowing for quicker replacement and adjustment of components, including the use of a spring washer and compression spring for tensioning, and a welded connection for robust assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screws are used to attach insert plates to ejector bases, then the insert plates can be releasably mounted, but the screws become rust-bound due to repeated exposure to hot and moist clay, requiring time-consuming drilling and retapping operations
Solution Approach 1:
The ejector base is divided into separate components: a base body and an insert plate that can be independently replaced. The insert plate is detached from the base body, allowing only the worn insert plate to be removed while retaining the base body, thus reducing replacement time and eliminating the need for retapping operations.
Solution Approach 2:
The insert plate is extracted as a separate replaceable component from the ejector base. By removing only the insert plate (not the entire base), the maintenance operation is simplified to just removing and replacing the insert plate, avoiding time-consuming drilling and retapping of the base screws.
2Reliability
If a complete ejector base replacement is performed, then worn ejectors can be replaced, but the mould container press cannot be employed for brick production for a considerable length of time
Solution Approach 1:
The ejector system is segmented into a permanent base body and a replaceable insert plate. This allows selective replacement of only the worn insert plate while retaining the functional base body, enabling quick maintenance that minimizes production downtime and maintains overall system reliability.
Solution Approach 2:
The insert plates are pre-manufactured as separate components and can be prepared in advance. When wear occurs, pre-prepared replacement insert plates can be immediately installed on the retained base bodies, eliminating the need for time-consuming on-site manufacturing or complete base replacement operations.
3Strength
If screws are repeatedly used in hot and moist clay environments, then insert plates can be securely attached, but the screws rust and require drilling out and tapping new threads
Solution Approach 1:
The screws are extracted from the maintenance operation entirely. Instead of removing and replacing screws, the insert plate itself is designed as a separate component that can be detached and replaced without involving screw operations, thereby eliminating rust issues and the need for drilling and retapping.
Solution Approach 2:
The insert plates are designed as disposable or limited-life components that are replaced rather than repaired. This approach is more economical than maintaining screws, as the insert plates can be quickly swapped without any fastening operations, eliminating the recurring cost and time of screw replacement.
