Abstract
The invention provides a method and apparatus for injection-molding at least a first part of a plastics manifold element onto an extruded, panel-forming plurality of juxtaposed, hollow elements, comprising the steps of introducing into one set of ends of the hollow elements protrusions which extend from a core defining the shape of at least part of the interior space of the final manifold to be formed; clamping the region of the set of ends accommodating the protrusions between first and second mold members which, together with the core delimit the cavity of at least part of the final manifold; injecting plastic material into the cavity; and removing the core, and the mold members, whereby a strong bond is formed between the hollow elements and the manifold.
Claims12
A method for injection-molding at least a first part of a plastic manifold element onto an extruded, panel-forming plurality of juxtaposed, hollow elements, comprising the steps of:
- introducing into one set of ends of said plurality of hollow elements protrusion means extending from a core means, said core means defining the shape of at least part of the interior space of the final manifold to be formed;
- clamping the region of said set of ends accommodating said protrusion means between a first and a second mold member, which two members, together with said core means, delimit the cavity of at least part of said final manifold;
- injecting plastic material into said cavity;
- removing said core means, and
- removing said first and second mold members, whereby during the injection-molding process a strong bond is formed at the interface between the material of said plurality of juxtaposed, hollow elements and the material of the manifold being formed.
An apparatus for injection-molding a plastic manifold onto an extruded, panel-forming plurality of juxtaposed, hollow elements, which apparatus comprises:
- core means defining the shape of the interior space of the final manifold to be formed, protrusion means extending from said core means, which protrusion means is designed to substantially fit and fill at least one end section of said hollow elements to prevent the collapsing thereof during injection-molding of said manifold thereon, said core means comprising a core rail carrying said protrusion means, an extractor member in which said core rail is slidably arranged, and a core jacket substantially surrounding said extractor member, said core jacket, together with a portion of said core rail, defining the interior space of said final manifold.
