Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for producing cast products with incorporated pipes, such as insert casting, require additional steps to remove incompressible fluids from the pipe after the cast product is extracted from the mold, prolonging production time and risking fluid splatter.

Innovation Solution

A method and device that allows for the injection and discharge of incompressible fluids through the pipe before and during the casting process, using a mold with movable parts to hold the pipe and a fluid transporter to manage fluid flow, ensuring efficient removal without post-mold handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the filling material is removed after the cast product is extracted from the mold, then the cast product can be produced with the pipe incorporated, but the production time is extended and the filling material may splatter outside

Engineering Contradiction:

Improveease of removing filling materialVSAvoidproduction time

Core Design Contradiction:

Ease of manufactureVSLoss of time

Solution Approach 1:

The filling material is removed from the pipe before the casting process begins. The pipe is prepared in advance with the filling material already extracted, so that when the pipe is inserted into the mold and the casting is completed, no additional removal step is needed. This preliminary preparation eliminates the time-consuming post-casting removal operation and prevents splatter during extraction.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the incompressible fluid is discharged after the cast product is extracted from the mold, then the casting process can be completed, but the fluid may splatter outside and additional handling equipment is required

Engineering Contradiction:

Improvecasting cycle speedVSAvoidfluid splatter

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The incompressible fluid is discharged from the pipe before the casting process is completed. The discharge operation is performed in advance while the pipe is still in the mold, ensuring that all fluid is removed before the cast product is extracted. This prevents fluid splatter during extraction and eliminates the need for additional handling equipment.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

A discharge container or receptacle is positioned to receive the incompressible fluid as it is discharged from the pipe. This intermediary container captures the fluid during the discharge process, preventing it from splattering outside and contaminating the workspace. The container serves as a mediator between the discharge opening and the external environment.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A production method includes a preparation step of preparing a mold including a fixed mold and a movable mold, disposing a pipe in the mold such that an injection opening and a discharge opening are exposed outside from the mold, closing the mold, injecting an incompressible fluid into the injection opening to fill a third flow path of a main portion of the pipe with the incompressible fluid, filling a molding space formed by the movable mold and the fixed mold with a melted metal material, discharging the incompressible fluid in the third flow path from the discharge opening, and separating the movable mold from the fixed mold to open the mold and extracting a cast product having the incompressible fluid discharged from the third flow path.
