The present invention provides a device for exercising a live hinge formed integrally between a vessel portion and a lid of an article during injection molding. In an embodiment, the device includes a core block for forming the vessel portion and a movable side core for forming the lid. The side core has a molding position for forming the article, and an ejection position for ejecting the article from the core block. The device also includes an exercising member that is movable with the side core. The exercising member closes the lid and exercises the hinge during travel from the molding position to the ejection position.

Apparatus for exercising a live hinge

Servo side shuttle apparatus and method for a molding machine includes structure and/or steps whereby a shuttle plate is disposed adjacent at least one of a first mold half and a second mold half of the molding machine. A guidance assembly is coupled to the mold half and guides the shuttle plate linearly across a molding face of the mold half. A drive mechanism is provided to drive the shuttle plate in a linear direction. An operation structure is coupled to the shuttle plate and is configured to perform an operation on a molded article disposed either in the mold cavity or on the mold core. The operation may include removing the molded article from a mold core, applying a label to a mold cavity, and/or closing the lid of a molded article while it is resident on the mold core.

Molded article work piece application method

Disclosed is a method of a mold-spraying apparatus for use with a molding apparatus. The mold-spraying apparatus has: (i) a spray nozzle, (ii) a rotatable shaft being supportive of the spray nozzle, and (ii) a camming surface. The method includes: (a) engaging the rotatable shaft with the camming surface, and (b) moving the camming surface so that the rotatable shaft may rotate.

Mold-spraying apparatus of molding system

Disclosed is an article moving apparatus configured to move an article relative to a first mold half and a second mold half of a molding machine. The article moving apparatus includes an arm configured to grasp and release the article, and also include an arm reciprocating structure configured to reciprocate the arm between an in-mold position and an out-mold position relative to the first mold half and the second mold half, and to be selectively retractable away from an abutment relationship relative to any one of the first mold half and the second mold half.

Article moving apparatus configured for a molding machine

Disclosed is an article moving apparatus.

Article moving apparatus configured for molding machine

Disclosed is: (i) a mold-spraying apparatus of a molding system and/or (ii) a molding system having a mold-spraying apparatus, and/or (iii) a method of a mold spraying apparatus of a molding system, and/or (vi) a method of a molding system having a mold-spraying apparatus, amongst other things.

Side shuttle apparatus and method for an injection molding machine

Servo side shuttle apparatus and method for a molding machine includes structure and/or steps whereby a shuttle plate has a portion always disposed inboard of a perimeter of a first mold half of the molding machine. Drive structure is preferably configured to drive the shuttle plate only in one plane across a molding face of the first mold half. A plurality of gripping structures are coupled to the shuttle plate and are respectively configured to remove a corresponding plurality of molded articles from a corresponding plurality of mold cavities (or cores). The drive structure is also configured to drive the shuttle plate to cause the plurality of gripping structures to be moved in a direction which is diagonal with respect to an array direction of the plurality of mold cavities (or cores).

An apparatus and method for folding a hinged molded part in a molding machine. As a part-removal apparatus, preferably a swing arm mechanism, grips one of the lid portion or the base portion of the molded part and moves the molded part out of the mold, a deflector connected to a portion of the mold engages the other portion of the part and initiates folding of the lid portion to the base portion at the hinge. The deflector further folds the part as the mold closes. The portions of the part are pushed together and latched in one embodiment by the swing arm mechanism that grips and moves the molded part against the deflector, and in another embodiment by a closing actuator operated separately from the swing arm mechanism.

Apparatus for closing a hinged molded part

A nozzle assembly for use in injection molding comprises a pair of spacers acting between the manifold and either a cover plate or a hot runner plate of an injection molding machine to apply a contact pressure between the nozzle body melt channel and the manifold melt channel to achieve a seal therebetween. The resilience of the spacers result in an increased operational temperature range for the nozzle assembly, the contact pressure being generated and/or maintained over the range of the operational temperatures. An additional advantage is provided in that the nozzle assembly is compact and can be closely spaced with similar nozzle assemblies to achieve center spacings as small as eight millimetres. The assemblies can be mounted and/or removed from the cavity of the manifold plate, and/or changing of the nozzle heater elements, without requiring removal of the mold from the injection mold machine. In one embodiment, the nozzle assemblies can be removed or mounted by removing a cover plate from the manifold plate, the cover plate being capable of retaining multiple nozzle assemblies in place. In another embodiment, the nozzle assembly has a mounting flange and one or more bolts extend through the and engage the manifold plate and these bolts allow mounting and removal of the nozzle assembly.

Injection molding nozzle assembly

The present invention relates to an apparatus for manufacturing a substantially flat article, such as a smart card, having at least one substantially flat edge. The apparatus includes a mold for forming the substantially flat article, which mold includes an inlet gate for allowing molten plastic material to flow into a cavity space defined by the mold. The apparatus further includes a source of molten plastic material, a passageway communicating with the inlet gate and the source of molten plastic material, and a blade or pin for pushing residual plastic material in the passageway into the cavity space formed so as to form a side edge for the substantially flat article having substantially no gate vestige. A method for manufacturing the substantially flat article is also described.

Sliding edge gate for a hot runner mold

Improved method and apparatus for injection molding particularly useful with multiple hot runner valve gates to fill a single large mold cavity. A hot runner injection nozzle is provided having a gate through which melt is injected into a mold cavity, and a valve stem is movable on the injection nozzle between an open position permitting flow of melt through the gate and a closed position blocking the flow of melt through the gate. The valve stem is movable to at least one position between the open and closed positions restricting the flow of melt through the valve gate.

Apparatus includes a female mold and a mold core cooperating with the female mold to form a mold cavity therebetween in the mold closed position for the formation of a threaded, mold article therein. A movable, rotatable stripper ring is provided over the core, and means are provided to rotate the stripper ring from a rearward to a forward position and thereby remove the threaded article from the mold core by rotating same. A process for forming a threaded, molded plastic article is disclosed including molding the article in an injection mold and removing the article from the mold by rotating a rotatable and movable unscrewing means to rotate and remove the article from the mold core.
