Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing mold production systems face challenges with costly and ergonomically difficult die frames, limited ejection system angular rotation, and potential mold damage during removal, due to specific ejection systems integrated into each matrix frame.

Innovation Solution

The casting table incorporates actuating means for ejection systems, including thrust and drive mechanisms that are movable through a housing within the die frame, allowing for increased stroke and reduced effort, and are designed to be actuated from the casting table rather than the die frame, facilitating easier handling and reducing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an ejection system is integrated into each die frame, then mold ejection function is achieved, but die frame cost and weight increase significantly

Engineering Contradiction:

Improvemold ejection functionVSAvoiddie frame weight

Core Design Contradiction:

ReliabilityVSWeight of stationary object

Solution Approach 1:

The ejection system is extracted from the die frame and relocated to the casting table. The casting table now incorporates the ejection mechanism, while the die frame is simplified to only contain the mold cavity and basic structural elements. This separation reduces die frame weight and cost while maintaining reliable mold ejection capability through the casting table's dedicated ejection system.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The casting table is given multiple functions: it serves as both the support structure for the die frame and the actuator for the ejection system. By integrating the ejection mechanism into the casting table, the same structure performs both structural support and active ejection functions, eliminating the need for a separate ejection system in each die frame.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If ejection system is integrated into die frame, then mold detachment is enabled, but handling and operation become difficult

Engineering Contradiction:

Improvemold detachment capabilityVSAvoiddie frame handling

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The complex ejection mechanism with cams, slots, and lever systems is extracted from the die frame and implemented in the casting table. This allows the die frame to be handled more easily as a simpler component, while the ejection function remains reliable through the casting table's integrated system.

Inventive Principle:

Principle #2Taking out (Extraction)

3Device complexity

If limited angular rotation is used in ejection system, then device complexity is reduced, but mold detachment distance is insufficient

Engineering Contradiction:

Improveejection system structureVSAvoidmold detachment distance

Core Design Contradiction:

Device complexityVSLength of moving object

Solution Approach 1:

Instead of relying on limited angular rotation of cams, the ejection system uses linear vertical movement of pistons and plunger elements. This dimensional change from rotational to linear motion provides sufficient detachment distance without requiring complex angular mechanisms, simplifying the overall device structure while achieving the required ejection stroke.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

4Productivity

If sudden ejection force is applied, then mold removal speed increases, but mold damage risk increases

Engineering Contradiction:

Improvemold removal speedVSAvoidmold damage risk

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The ejection process uses a controlled sequential action where pistons and plunger elements move in a regulated manner rather than sudden impact. The system applies ejection force through a controlled periodic motion that achieves efficient mold removal while minimizing shock and damage risk through gradual force application.

Inventive Principle:

Principle #19Periodic action
