摘要:
Molded plastic articles are prepared in accordance with the process and apparatus of the present invention. A first mold cavity is filled via a feeding unit in engagement with a first mold cavity with plastic containing a volume expanding agent, the filled first mold cavity and feeding unit are moved away from each other and a second mold cavity and the feeding unit are moved into engagement with each other, the second mold cavity is filled with plastic containing a volume expanding agent via the feeding unit, the plastic is expanded in the first mold cavity via the volume expanding agent while the second mold cavity is in engagement with the feeding unit, and the expanded article is ejected from the first mold cavity.
摘要:
An injection molding machine of the present invention includes a first mold half having one of at least one mold cavity and at least one mold core and a rotatable turret block rotatable on an axis for rotating a plurality of movable mold halves thereof into alignment with the first mold half. Each of the movable mold halves include one of at least one mold cavity and at least one mold core matable with the first mold half for forming a mold for molding a molded article. The rotatable turret block is further for clamping the movable mold halves and the first mold half together. The machine further includes a mechanism for moving the rotatable turret block relative the first mold half a first injector for injecting melt into the at least one mold cavity.

An injection mold for an injection molding machine includes a first mold half having one of at least one mold cavity and at least one mold core. The first mold half is mounted on a rotatable turret block rotatable on an axis perpendicular to the central axis of the first mold half for rotating the at least first mold halves thereof into alignment with the second mold half. The first mold half is moved towards and away from the second mold half via means for moving, wherein the second mold half is stationary and supported by a frame. The rotatable turret block is further for clamping the first mold halves and the second mold half together.
