Solution Overview

Problem

Existing methods for manufacturing molding dies face challenges in detaching the base plate and stacking body efficiently, leading to degraded processing efficiency and prolonged processing time due to strong adhesion between the two components.

Innovation Solution

The method involves assembling a base plate by inserting a second member, configured by a plurality of nest members, into an opening portion of a first member, shaping a stacking body by ejecting a shaping material onto the base plate, and removing the second member after stacking, utilizing through holes and female screw portions for easy detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If through holes are formed in the base plate to improve adhesion between base plate and stacking body, then adhesion strength is improved, but detachment becomes difficult and processing time is prolonged

Engineering Contradiction:

Improveadhesion strengthVSAvoidprocessing time

Core Design Contradiction:

StrengthVSLoss of time

Solution Approach 1:

The base plate is divided into a first base plate and a second base plate that can be detached from each other. The second base plate is configured with through holes to provide adhesion, while the first base plate can be separated from the second base plate after shaping, enabling easy detachment and reducing processing time.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The second base plate with through holes is extracted as a separate component from the first base plate. This allows the through holes to provide adhesion during shaping while enabling easy removal of the second base plate after the stacking body is formed, thus resolving the contradiction between strong adhesion and easy detachment.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of manufacture

If a single solid base plate is used to ensure structural integrity, then manufacturing simplicity is maintained, but adhesion control and detachment difficulty arise

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoiddetachment ease

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The base plate structure is segmented into two detachable parts: the first base plate and the second base plate. This segmentation allows the second base plate to have through holes for controlled adhesion while maintaining overall structural integrity, and enables easy detachment when needed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The second base plate acts as an intermediary component between the first base plate and the stacking body. It provides the through holes necessary for adhesion control while being detachable, thus mediating between the requirements for strong adhesion and easy detachment.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Assembling a base plate by inserting a second member into an opening portion of a first member, the second member being configured by a plurality of nest members, shaping a stacking that is to be a part of the molding die by ejecting a shaping material onto the base plate and stacking a layer, removing the nest members from the base plate on which the stacking body was shaped, and subjecting the stacking body to a cutting process are involved. During assembling of the base plate, the plurality of nest members are arrayed and inserted to fill the opening portion.
