US 2026/0175508 A1 · SYSTEM AND METHOD FOR BLOW MOLDING PLATE COMPONENTS FOR ARTICLES OF FOOTWEAR

Abstract

A blow molding system includes an extrusion system including at least one extruder configured to extrude a parison having an interior cavity and a blow pin configured to extend into the interior cavity of the parison extruded from the extrusion system. The blow molding system also includes a mold assembly at least partially defining a mold chamber configured to receive the parison. The mold chamber includes a mold surface defining a profile of a sole component of an article of footwear. The blow molding system further includes an upper opposing the mold surface and at least partially defining the mold chamber. The upper is configured with a bottom surface to receive a portion of the parison upon inflation of the parison by the blow pin.

Dependent claims

A blow molding system comprising:

a first extruder extruding a first material forming a first layer of a parison having an interior cavity;
a first mold half disposed adjacent to the first extruder and having a first mold cavity defining a profile of at least one sole component of an article of footwear;
a second mold half supporting an upper relative to the first mold half, the first mold half and the second mold half cooperating to define a mold chamber between the first mold cavity and the upper in a closed state;
and
a blow pin extending into the interior cavity of the parison, the blow pin injecting pressurized fluid into the interior cavity of the parison to urge the parison into engagement with the first mold cavity and the upper.
