Abstract: An apparatus for rotational molding provides a mold having first and second mold components defining therebetween a mold cavity. The first mold component includes a mold insert adapted to translate toward the second mold component. A spring-biased latch mechanism restrains the mold insert in the outward disposition, and a touch pad is struck to trigger the latch mechanism and urge the mold insert inwardly while the mold is rotating. With the mold insert latched in the outward disposition, the rotational mold charged with thermoplastic material rotated biaxially and heated. After heating, while the mold assembly continues to rotate, the touch pad is struck to release the latch and cause the mold insert to move inwardly. The mold insert includes structural features that are moved more proximate to opposed mold portions.
