Corrugated Pipe Mold Jaw Return Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for producing corrugated pipes from thermoplastic face inefficiencies in the return of mold jaws, leading to slower production rates due to limitations in the movement and attachment mechanisms of the return conveying device.
Innovation Solution
The introduction of drive means that can move perpendicularly to the plane of the supporting table in both the inlet and outlet assemblies, allowing for more efficient movement and attachment of mold jaws, enabling faster return and increased production rates by reducing the time required for the return of mold jaws and allowing multiple mold jaws to be processed simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional return conveyors with gripping arms are used to move mold jaws back and forth, then the mold jaws can be returned to the beginning of the mold section, but the production rate is limited due to the sequential operation and time required for gripping and moving each mold jaw individually
Solution Approach 1:
The patent applies dynamics by making the drive means movable perpendicular to the supporting table plane, allowing the system to transition between different operational states (engaged/disengaged) dynamically. This enables the drive means to quickly attach to and detach from mold jaws without complex gripping mechanisms, significantly reducing the time for mold jaw return operations and increasing production rate.
Solution Approach 2:
The patent introduces movement in a new dimension by allowing drive means to move perpendicular to the plane of the supporting table. This vertical movement capability enables the drive means to engage with and propel mold jaws from below, eliminating the need for lateral gripping arms and enabling faster, more efficient mold jaw return operations.
2Productivity
If drive means are positioned only in the plane of the supporting table, then the structure remains simple, but the ability to efficiently move and attach multiple mold jaws simultaneously is limited
Solution Approach 1:
The drive means is designed to be dynamically positionable in the vertical direction, allowing it to engage with multiple mold jaws at different positions simultaneously. This dynamic capability enables the system to process multiple mold jaws in parallel, significantly increasing productivity while the overall structural complexity remains manageable due to the straightforward vertical movement mechanism.

AI summary
The invention under consideration concerns a device for the production of corrugated pipes made of thermoplastic, in which mold jaws, which complement each other in pairs, are conducted jointly in a cycle along a mold section that leads away from an extruder head; they are moved apart at the end of the mold section and are returned to its beginning separately from one another with a mold section device for the movement of the mold jaws along the mold section, which has a supporting table with drive means for the mold jaws on the mold section, and with a return conveying device for the return conveyance of the mold jaws from the end of the mold section to its beginning, which has an outlet assembly to move apart the mold jaws at the end of the mold section and/or an inlet assembly to move in the mold jaws at the beginning of the mold section. In accordance with the invention, the outlet assembly and/or the inlet assembly have drive means, which can be moved perpendicularly with reference to the plane of the supporting table.
