Abstract
A shift detecting element originates from an element cavity, a portion of which is defined in one portion of a mold section and another portion of which is defined in another cooperating mold section. The detecting element is cast as an appurtenance to a principal casting and is configured such that it can be easily removed from the principal casting. Misalignment or separation is determined by inspection and/or measurement of the cast shift detecting element.
Claims9
A method for detecting misalignment or separation of cooperating mold sections which comprises the steps of
- forming cooperating mold sections,
- forming a product mold cavity within said cooperating mold sections,
- forming a detecting element cavity within said cooperating mold sections,
- casting a product within said cooperating mold sections,
- casting a detecting element within said cooperating mold sections,
- removing said detecting element from said cooperating mold sections, and
- measuring said detecting element with a measuring means whereby an misalignment or separation of said cooperating mold sections is detected and measured.
A method for detecting misalignment or separation of cooperating mold sections which comprises the steps of
- forming a first mold section to define and to form a product mold cavity therewithin,
- forming a second mold section, said second mold section being functionally adapted to cooperate with said first mold section,
- locating a product mold cavity and a shift detecting element cavity within said mold sections,
- defining said product mold cavity and said shift detecting element cavity within said mold sections,
- casting said product and said shift detecting element within said shift detecting element cavity,
- removing said product and said shift detecting element from said mold sections, and
- measuring said detecting element with a measuring apparatus whereby any misalignment or separation of said mold sections is detected and measured.
A method for detecting misalignment or separation of cooperating mold sections which comprises the steps of
- forming cooperating mold sections,
- forming an interior cavity within said mold sections,
- a portion of said interior cavity defining the outer surface of a product mold cavity and portion defining the outer surface of a detecting element,
- casting a product and a detecting element within said interior cavity,
- removing said detecting element from said mold sections, and
- biasing said detecting element against a measuring device whereby any misalignment or separation of said cooperating mold sections is detected and measured.
