Powder Slush Molding Table Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In powder slush molding systems, simultaneous production using multiple molds as many as the number of working devices requires excess facilities, leading to increased installation space and equipment investment, particularly when using a transfer device or temporary-placement stage.
Innovation Solution
A powder slush molding system that secures temporary-placement space for demolded molds using an existing working device, specifically by configuring the cooling device's table to turn upside down, allowing molds to be placed on its back surface, thereby utilizing existing facilities to transfer molds efficiently without expanding installation space or equipment investment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a transfer device or temporary-placement stage is added to enable simultaneous production using five molds, then productivity is improved, but installation space increases and equipment investment becomes large
Solution Approach 1:
The cooling device's table is designed to perform multiple functions: it serves as the cooling surface during the cooling process and as a temporary-placement stage for demolded molds. By making the table movable and reconfigurable, the same equipment structure fulfills both cooling and temporary storage roles, eliminating the need for separate temporary-placement stages and reducing installation space requirements.

3Manufacturing precision
If molds are transferred sequentially through multiple devices, then manufacturing precision is maintained, but loss of time increases
Solution Approach 1:
The system positions the cooling device's table in advance to serve as a temporary-placement stage, so that when a mold completes demolding, the receiving position is already prepared. This eliminates waiting time and allows continuous mold circulation without interruption, maintaining transfer reliability while reducing cycle time.

AI summary
Disclosed is a powder slush molding system that molds a slush skin by melting and adhering a powder resin material to an inner surface of a mold that is heated. The powder slush molding system includes a heating device, a rocking device, a cooling device, a demolding device, and a transfer device configured to transfer the mold between these devices. The cooling device includes a cooling bath and a table configured to turn upside down vertically above the cooling bath. The mold fixedly placed on an upper surface of the table faces the cooling bath side when the table is turned upside down. The table is configured to allow the mold to be placed also on a back surface of the table. The back surface faces upward when the table is turned upside down.
