A hot runner nozzle tip and hot runner nozzle tip components are disclosed, the nozzle tip, and the assembled tip components, form a channel that has a first annular segment that has a cross-sectional area that increases in size away from a tip inlet, and a second annular segment that extends from the first annular channel segment. A hot runner tip assembly is also disclosed. The hot runner tip assembly includes a tip component having an attachment portion, an extension portion that projects from the attachment portion, and a bore that extends therethrough. A sleeve having a rib that extends outward therefrom surrounds the extension portion. The sleeve contacts the tip component at a first contact area and at a second contact area so as to create a void therebetween, and the first and second contact areas are offset from the rib.

An injection unit positioning apparatus is disclosed that includes a positioning assembly interconnecting the injection unit to the molding machine. The positioning assembly includes an angular positioning assembly that permits rotation of the injection unit through a sweep plane that extends from an axis that is perpendicular to an inlet surface of a mold. The positioning assembly also includes a linear positioning assembly that permits linear translation of the injection unit on the sweep plane, and the height of the outlet relative to the inlet surface remains substantially constant during rotation and translation of the positioning assembly.

Injection unit positioning apparatus

An edge-gated injection molding apparatus is disclosed for distributing a melt stream to a plurality of mold cavities aligned on opposing sides of an injection manifold assembly. The injection manifold assembly includes melt outlets aligned on opposing sides thereof with a nozzle seal in fluid communication with each melt outlet for transferring the melt stream to a corresponding mold cavity. A sliding relationship between each nozzle seal and its respective melt outlet while the nozzle seal is securely held relative to the mold gate permits misalignment between the nozzle seal and its respective melt outlet in the cold condition without causing stress on the nozzle seal. Under operating conditions, the sliding relationship permits subsequent alignment between the nozzle seal and its respective melt outlet. The nozzle seal has a two-piece gate seal with components thereof threadably coupled to each other such that relative rotation therebetween applies a sealing preload.

Edge-gated injection molding apparatus

An injection molding system is disclosed that includes a mold insert set and a shaft locking assembly that releasably attaches the mold insert set to a mold plate of the injection molding system. Each mold insert of the mold insert set defines at least a portion of a mold cavity. The shaft locking assembly is displaceable between a locked position in which the mold insert set is held to the mold plate and an unlocked position in which the mold insert set is removable from the mold plate.

Quick-change molding system for injection molding

A molding system is disclosed that includes a plurality of cavity portions or core block assemblies attached to a mold plate and a plurality of core portion or core block assemblies attached to a second mold plate, and a plurality of stripper rings or thread split-slide assemblies attached to a stripper plate assembly. The stripper plate assembly includes a main stripper plate with one or more stripper plate panels coupled thereto that are translatable away from the main stripper plate during installation of at least the core portions or core block assemblies. The one or more stripper plate panels may be translatable to fold, outwardly swing, and/or slide relative to the main stripper plate to clear any core portions or core block assemblies that may have been previously installed.

An auxiliary injection unit is disclosed that has an extruder barrel and extruder screw integrated within an injection molding system. The extruder barrel and extruder screw are contained within a mold plate of the injection molding system with a drive mechanism of the auxiliary injection unit being external thereof. A melt stream emanating from the extruder barrel of the auxiliary injection unit is in selective fluid communication with either a melt channel of a manifold providing melt thereto during an injection cycle or with a discharge channel of a melt discharge tube for purging melt. A melt diverter component receives the melt stream from the extruder barrel and includes a shuttle valve slidably positioned therein that is operated to selectively divert the melt stream produced by the auxiliary injection unit to either the melt channel of the manifold or the discharge channel of the discharge tube.

Disclosed, amongst other things, is: a continuous molding machine, a cam of the continuous molding machine, a post-molding device of the continuous molding machine, a molded article handling device, amongst other things.

Continuous molding machine

An in-mold system and method for handling molded articles. An in-mold lid handling system provides a slide that is operable to translate laterally across a molding face of an injection mold to perform a first operation on, or to retrieve a plurality of molded articles from, a column of molding cavities and to thereafter retreat to an outboard position for a second operation, or to transfer the molded articles to drop chutes. The driving means for the slide include a first and a second transmission attached to the ends thereof. The transmissions operate on the same basic principle wherein at least one belt contained therein is configured along a path defined by a plurality of guides, the path including a plurality of segments defined between the guides, and the at least one belt being operable along the path between two positions, wherein the slide is attached to various suitably arranged path segments and is thereby driven between the inboard and the outboard positions respectively.

Simplified in-mold article handling system and a method for handling molded articles

The present invention relates to a carrier assembly for supporting the mold center section of a stack mold. The carrier assembly has a pair of mold supports to which the mold center section can be attached. Each mold support is movable along a linear rail attached to the base of a molding machine and has at least one block containing a linear bearing mounted thereto for engaging the linear rail. Each mold support further includes a linkage assembly for connecting the mold support to other platens so as to synchronize movement of each mold support with movement of at least one other platen.

Stack mold carrier mounted on linear bearings

A high speed, automatic device for removal of molded plastic articles from a multicavity injection mold including a method of minimizing molding machine cycle time.

Pivoting workpiece removal method

An injection molding machine having a plurality of axially arranged mold stations including structure for supporting sets of mold plates and a mechanism for opening, closing and overstroking mold plates.
