Solution Overview

Problem

Short molding products, such as preforms, are prone to falling or tilting during the taking-out process due to gaps between the take-out machine and the mold, leading to potential collisions with the inner surfaces of the take-out tubes and deformation of the products.

Innovation Solution

A molding product taking-out system that includes a molding machine with a stationary and movable platen, a take-out machine, and a control device. The control device coordinates the movement of the take-out machine and the movable platen to ensure the molding product approaches the take-out machine, preventing falls and collisions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the take-out machine enters between the opened molds to take out the molding product, then the taking-out process can be performed, but gaps between the take-out machine and the mold cause the molding product to fall or tilt, leading to collisions with the inner surfaces of the take-out tubes and product deformation

Engineering Contradiction:

Improvetaking-out processVSAvoidproduct deformation

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

Instead of moving the take-out machine toward the molding product in a fixed position, the invention inverts the approach by moving the mold (specifically the movable mold half) toward the take-out machine. This reversal of motion direction eliminates gaps between the take-out machine and the mold, preventing the molding product from falling or tilting during the taking-out process, thereby avoiding collisions with the take-out tube inner surfaces and product deformation.

Inventive Principle:

Principle #13The other way round (Inversion)

2Productivity

If the take-out machine moves between opened molds, then the molding product can be accessed, but the molding product is prone to falling or tilting due to gaps, causing collisions and deformation

Engineering Contradiction:

Improvetaking-out efficiencyVSAvoidproduct integrity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The invention reverses the conventional motion approach: rather than the take-out machine moving to access the molding product, the movable mold half moves toward the take-out machine. This inversion eliminates gaps during the taking-out operation, ensuring the molding product remains stable and intact, thus maintaining both productivity and product integrity.

Inventive Principle:

Principle #13The other way round (Inversion)

3Adaptability or versatility

If gaps exist between the take-out machine and the mold, then the take-out machine can be positioned between opened molds, but the molding product falls or tilts and collides with the inner surfaces of the take-out tubes

Engineering Contradiction:

Improvetake-out machine positioningVSAvoidproduct collision and deformation

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The invention inverts the motion strategy: instead of positioning the take-out machine and having gaps remain, the movable mold half moves toward the take-out machine. This eliminates the harmful gaps that cause the molding product to fall or tilt, preventing collisions with the take-out tube inner surfaces and subsequent product deformation, while still allowing the take-out machine to be positioned between opened molds.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A molding product taking-out system includes a molding machine that includes a stationary platen including a stationary mold and a movable platen including a movable mold, a take-out machine for taking out a molding product, and a control device, in which the control device causes the take-out machine to enter between the stationary mold and the movable mold that are opened, and moves at least one of the movable platen and the take-out machine such that the molding product relatively approaches the take-out machine.
