HOT-PRESS MOLDING APPARATUS, AUTOMOTIVE BODY COMPONENT, HOT-PRESS MOLDING METHOD, AND AUTOMOTIVE BODY COMPONENT MANUFACTURING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240033802 titled 'HOT-PRESS MOLDING APPARATUS, AUTOMOTIVE BODY COMPONENT, HOT-PRESS MOLDING METHOD, AND AUTOMOTIVE BODY COMPONENT MANUFACTURING METHOD

Simplified Explanation

The abstract describes a hot-press molding apparatus used for molding metal sheet material. It consists of an upper mold with a molding surface and a blade serving as a punch, a lower mold with a molding surface for sandwiching the to-be-molded portion in cooperation with the upper mold, and a die that separates a trimming portion from the to-be-molded portion. The outer side surface of the upper mold is designed to extend in the cutting direction of the punch and creates a cooling suppression space that prevents cooling of the trimming portion.

  • The hot-press molding apparatus includes an upper mold, a lower mold, and a die.
  • The upper mold has a molding surface for molding a to-be-molded portion of a metal sheet material.
  • The lower mold has a molding surface for sandwiching the to-be-molded portion in cooperation with the upper mold.
  • The die separates a trimming portion from the to-be-molded portion in the metal sheet material.
  • The outer side surface of the upper mold extends in the cutting direction of the punch.
  • The outer side surface defines a cooling suppression space that prevents cooling of the trimming portion.
  • The apparatus prevents delayed fracture in the molded product.

Potential applications of this technology:

  • Automotive industry: This hot-press molding apparatus can be used for manufacturing various metal sheet components used in automobiles, such as body panels, structural parts, and engine components.
  • Aerospace industry: The apparatus can be utilized for producing metal sheet parts for aircraft, including fuselage components, wings, and landing gear parts.
  • Consumer electronics industry: This technology can be applied to manufacture metal sheet components used in electronic devices, such as smartphone casings, laptop frames, and tablet enclosures.

Problems solved by this technology:

  • Delayed fracture prevention: The hot-press molding apparatus prevents the occurrence of delayed fracture in the molded product, ensuring its structural integrity and durability.
  • Efficient trimming: The die separates the trimming portion from the to-be-molded portion, allowing for precise and efficient trimming of excess material.

Benefits of this technology:

  • Enhanced product quality: By preventing delayed fracture, the hot-press molding apparatus ensures that the molded products have high structural integrity and reliability.
  • Cost and time savings: The efficient trimming process reduces material waste and saves time during production.
  • Versatility: The apparatus can be used for molding various metal sheet materials, allowing for a wide range of applications in different industries.


Original Abstract Submitted

a hot-press molding apparatus includes an upper mold () having a molding surface for molding a to-be-molded portion () of a metal sheet material () and a blade () serving as a punch (), a lower mold () having a molding surface () for molding the to-be-molded portion by sandwiching it in cooperation with the upper mold, and a die () configured to separate, from the to-be-molded portion, a trimming portion () positioned outside the to-be-molded portion in the metal sheet material in which the to-be-molded portion is molded by the upper mold and the lower mold, in cooperation with the blade of the upper mold. an outer side surface () of the upper mold is so formed as to extend in the cutting direction of the punch, and defines, on the side of the upper mold, a cooling suppression space () to which the trimming portion is exposed and which suppresses cooling of the trimming portion. a hot-press molding apparatus capable of preventing the occurrence of delayed fracture in a molded product is provided.
