Blow molding tool with thermal insulation for plastic containers
The patent US12064915B2 describes a blow molding tool designed for use in blow molding machines, featuring two mold halves that house a molding body with at least one mold cavity. A key innovation is the inclusion of an insulation block made from thermally insulating material, which is positioned between the molding body and the baseplate. This configuration ensures that the molding body is thermally insulated from the baseplate, while also incorporating channels on the rear side of the molding body that facilitate heating and cooling circuits. These circuits allow for the controlled flow of temperature-regulated heating or cooling mediums, enabling efficient temperature management during the molding process.
The claims further detail the construction and materials of the blow molding tool, including the embedding of the molding body within the insulation block and the potential for a unified molding block structure. The insulation block is specified to be made from high-temperature-resistant plastics, such as polyaryl ether ketones and glass-fiber-reinforced plastics, ensuring durability and low thermal conductivity. The tool can accommodate multiple molding bodies, each thermally insulated, and is adaptable for use in both extrusion and stretch blow-molding machines. Additionally, the patent outlines a method for producing plastic containers, detailing the steps from heating the molding body to cooling it post-molding, with specific temperature ranges for the heating and cooling mediums. This method aims to produce containers with desirable surface finishes, enhancing the quality of the final product.
