An apparatus simultaneously operates all split locking nuts of an injection molding machine two-platen clamp unit to engage and disengage the split locking nuts with clamp unit strain rods. Each split locking nut has opposed pivoting nut halves operated by coupling rotation of a rotating member through a predetermined angular range to the nut halves via translating members such as push rods. The push rods are pivotably connected to the rotating member and to the nut halves so that the direction of each push rod relative to the rotating member and to the nut half changes with rotation of the rotating member. A method of molding comprises: disengaging split locking nuts from strain rods; positioning a moveable platen assembly to abut mating mold components; simultaneously operating the split locking nuts to engage the strain rods; and, applying force to the abutted mold components sufficient for injection and cure of melt.

Apparatus and method for injection molding

A block former comprises a portable device for compression forming of carbon dioxide particles into a non-homogenous block of carbon dioxide. The formed non-homogenous block can be used with carbon dioxide blasters that shave the formed block, and then eject the carbon dioxide shavings into a pneumatic jet as a blast media for cleaning surfaces. The block former further comprises a control system comprising a logic system of switches, valves, and timers to perform a timed sequence of events to form loose carbon dioxide particles into a non-homogenous block, to release compression on the block, and to eject the formed block from the block former. A single compression surface is provided to compress the carbon dioxide particles block, to release pressure on the block, and to eject the block from the block former device. The carbon dioxide particles used to form the non-homogeneous block can vary in size from snow to chunks or pellets.

Method and apparatus for forming carbon dioxide particles into a block

An apparatus for forming a block from carbon dioxide particle is configured to allow changing between precise thicknesses with very little downtime, utilizing both weight based and volumetric dosing. A spacer supports the lower ejection piston during block forming, with a shuttle discharging particles into the forming chamber while simultaneously pushing a previously formed block on to a conveyor. In one embodiment, the shuttle dosing cavity has a volume that is greater than the volume of the forming chamber volume, which allows more pellets, volumetrically, to be dosed into the dosing cavity than the volume of the forming cavity.
