Abstract
Three-dimensional articles are molded from materials capable of flow utilizing A. a molding zone having a plurality of advancing contiguous molds with adjacent molds forming mold cavities at contiguous interfaces transverse to the direction of motion. B. a discharge zone following the molding zone wherein said molds travel in an arcuate path, become separated from each other and the mold cavities are opened; C. feeding a material capable of flow to the molding zone, forcing same into said mold cavities and solidifying same therein; and Withdrawing said molded articles from the discharge zone.
Claims13
Continuous molding apparatus for molding a plurality of three dimensional articles comprising
- a. carrier means adapted to travel in a first path followed by a arcuate path
- b. a plurality of contiguous mold means, said mold means having transverse and mutually adjacent pairs of faces which are transverse with respect to the carrier means, mounted on said carrier means adjacent ones of said mold means forming undercut mold cavities in said transverse and mutually adjacent pairs of faces of said mold means when said carrier means travels in the said first path, said mold faces containing said undercut mold cavities separating from each other and opening said mold cavities when said carrier means travel in said arcuate path
- c. means for feeding and forcing a material capable of flow into the said mold cavities.
