Solution Overview
Problem
Existing molding units for forming containers with hollow recesses, such as handles, face challenges in compactness, ease of use, and maintenance due to the complexity of pneumatic and fluid circuits in wallet-type molds, which are not easily replicable from linear-type molds and require significant radial space and lateral access.
Innovation Solution
A molding unit design featuring a fluid circuit and pneumatic circuit integrated into the mold's upper surface, with passages drilled for thermal regulation and actuator control, allowing for compactness, ease of use, and maintenance by simplifying fluid and pneumatic connections through the upper surface, reducing radial bulk and facilitating easier access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connectors are connected from the side on the mold, then fluid supply for pneumatic circuit is ensured, but radial bulk of the molding unit increases and maintenance becomes complex
Solution Approach 1:
The patent transitions from lateral connector connections to upper-surface connections, changing the spatial dimension of fluid supply access. This dimensional shift allows connectors to be positioned on the upper surface of the mold rather than on the lateral side, reducing radial bulk while maintaining fluid supply reliability
2Reliability
If connectors are connected from the side on the mold, then fluid supply for pneumatic circuit is ensured, but ease of maintenance deteriorates due to difficulties of lateral access
Solution Approach 1:
The patent repositions connector connections from the lateral dimension to the upper surface dimension, making connectors accessible from above rather than from the side. This dimensional change significantly improves maintenance access while preserving fluid supply functionality
3Adaptability or versatility
If molding unit is designed for wallet-type molds with insert movement control, then container forming with hollow recesses is achieved, but considerable radial space is required
Solution Approach 1:
The patent relocates pneumatic connector connections from the radial/lateral dimension to the axial/upper surface dimension. This allows wallet-type molds to maintain their compact radial profile while still providing necessary access points for pneumatic circuits through the upper surface

Implementation Method 1
a fluid circuit for thermal regulation of the wall, which includes passages drilled in it
Implementation Method 2
the thermal regulation is ensured by means of a fluid circuit comprising passages drilled in the wall of the mold, supplied with fluid by external tubes
Implementation Method 3
the actuator is generally controlled pneumatically (i.e., with the aid of a pressurized fluid)
Implementation Method 4
a pneumatic circuit for controlling the actuator
Implementation Method 5
the blank, previously heated so as to enable its plastic deformation
Implementation Method 6
conforming to the wall under the effect of the high gas pressure that prevails in the blank
Implementation Method 7
the molds must be thermally regulated, to be kept either at a low temperature (typically on the order of 10° C.) so as to cool the container—and therefore to set—the material of the container
Implementation Method 8
or at a high temperature (typically on the order of 140° C.) so as to ensure a heat setting of the material at the end of forming, making it possible to increase its crystallinity
