A modular barrel and screw assembly for use in injection molding including a barrel having a barrel body, a separate barrel injection portion and a separate barrel end cap, with the barrel end cap being removably connected to the barrel injection portion and the barrel injection portion being removably connected to the barrel body, and a screw assembly having a screw tip assembly removably connected to a screw portion, wherein an injection chamber having a shot volume is defined by the barrel injection portion, the barrel end cap and the screw tip assembly. The modular barrel and screw assembly enables servicing of the barrel injection portion, barrel end cap and/or screw tip assembly without requiring removal of the barrel body, and enables use of a plurality of alternative corresponding separate barrel injection portions, separate barrel end caps and tip assemblies that provide a plurality of different shot volumes.

A molding die has a lower holder, an intermediate holder, an upper holder, a lock member, an upper link bar, a lower link bar, a restriction member, and a drive part. A movement of the lock member in a molding die opening direction or a molding die closing direction is restricted by the intermediate holder. The upper link bar has a first retaining groove in which the lock member fits when being located at a molding die closing position. The lower link bar has a second retaining groove in which the lock member fits and a release portion that enables the lock member to be released from the first retaining groove. The restriction member is movable between a restriction position that prevents the lock member from fitting in the second retaining groove and a free position that enables the lock member to fit in the second retaining groove.

An apparatus for molding a physical body comprising at least two mold materials, wherein the apparatus comprises a first mold tool and a second mold tool configured for defining a mold volume in between in which the physical body is moldable by supplying the at least two mold materials, and a supply unit configured for separately supplying the at least two mold materials to the mold volume, wherein at least part of at least one of the first mold tool and the second mold tool is movable to thereby increase the dimension of the mold volume after having supplied the first mold material to the mold volume and before and/or during supplying the second mold material to the mold volume.

A workpiece clamping device able to perform a set-up changing operation for clamping members depending on the kind of a workpiece to be processed, at a low cost, by a simple method. The workpiece clamping device includes a bracket, a movable part which is movable with respect to the bracket, a clamping member to be attached to and detached from the bracket or the movable part, to clamp a workpiece, and a detachable device for detachably coupling the bracket or the movable part to the clamping member.

An injection molding machine includes a base, a stationary platen fixed to the base for holding a first mold section, and a moving platen for holding a second mold section. The moving platen is slidably supported on a platen slide surface fixed to the base and moveable along a machine axis between a mold closed position, in which the moving platen is drawn towards the stationary platen, and a maximum daylight position, in which the moveable platen is spaced axially apart from the stationary platen by a platen opening. The machine further includes a carriage support structure slidably supporting a stack mold carriage for holding a mold center section. The stack mold carriage is translatable parallel to the machine axis between a carriage advanced position and a carriage retracted position spaced axially apart from the carriage advanced position by a carriage stroke length. The carriage support structure includes a pair of beams removably fixed relative to the base, the beams extending parallel to the machine axis and spaced apart from each other by a lateral spacing, each beam having a beam length that is less than the platen opening and greater than the carriage stroke length.

There is provided a structure for positioning a first mold part of a mold on a mold mounting face in an injection molding machine. The structure comprises a positioner configured to connect the first mold part to part of the injection molding machine, wherein the positioner is adjustable to position the first mold part on the mold mounting face. The structure further comprises controller executable instructions executable in a controller with which to resolve an alignment parameter of the mold using a feedback signal from a sensor. Further provided is a method of operating an injection molding machine which method comprises the steps of positioning a first mold part of a mold on a mold mounting face using a positioner and appreciating an alignment parameter of the mold with reference to a feedback signal from a sensor.

The inventive method for making a medical device includes providing a micro plastic tube; molding a hub onto the tube; trimming the tube to a predetermined length; molding a tip onto the tube, and creating a tip that contains a micro orifice at a predetermined angle.

An injection mold, in particular for encapsulating rotors of electric machines, has a mold, wherein the mold has an arrangement of mold segments. The arrangement forms, along a longitudinal axis, a cavity for a component to be arranged. An exchange unit is provided, which is designed to remove at least one mold segment from and/or insert at least one mold segment into the arrangement, with the result that a size of the cavity can be changed.

A method for manufacturing a molded part by an injection molding machine while changing between multiple molds, the method including transporting a stack mold including an intermediate mold to a molding operation position inside the injection molding machine, wherein the intermediate mold includes a first unit for closing a first opening portion for delivering a resin to a cavity and a second unit for closing a second opening portion for receiving the resin from a next to the intermediate mold, the next mold including a third unit for closing a third opening portion for receiving the resin, injecting the resin into the mold, closing the opening portions by the first unit, second unit, and third unit, and unloading the mold from the molding operation position after the resin is injected into the mold, where the first, second, and third opening portions are closed in this order.

A method for manufacturing a molded part while changing between multiple molds including a first ejecting step of opening a first mold and ejecting the molded part from the first mold, a checking step of checking the ejected molded part to determine if the molded part is acceptable, a first injecting step of closing the first mold and performing injection into the first mold, a second ejecting step of, where the ejected molded part is determined to be acceptable, changing the first mold to a second mold and ejecting the molded part from the second mold after the first injecting step, and a third ejecting step of, in a case where the molded part ejected in the first ejecting step is determined to be non-acceptable, not changing the first mold to the second mold and ejecting the molded part from the first mold.
