摘要:
A monitor for maintaining a mold cycle count with an actuator sending a count signal to a processor following a mold operation. The monitor further includes a timer having an active mode and a sleep mode. The processor generates an average cycle time and an activity percentage of the mold taking into account active and sleep periods of the mold.
摘要:
A monitor for maintaining a mold cycle count and other mold operation data and a corresponding system that generates a first remote record of the mold cycle data and a second remote record of the mold cycle data, the second remote record comprising a lesser, different and/or non-confidential version of the first remote record. The first remote record and the second remote record may then be coordinated among an OEM manufacturer, a moldmaker and a molder.

A friction puller for an injection mold is disclosed. The friction puller has a bolt with a head portion and a threaded portion. The friction puller has first and second first substantially hemispherical wedges having a first and second passages running through them for the bolt and allow lateral float about the bolt. The friction puller also has a deformable jacket having a third passage running through is for the bolt and first and second substantially hemispherical cups for receiving the first and second substantially hemispherical wedges. The first hemispherical wedge can have a vent relief notch disposed in a top surface of the first hemispherical wedge. The deformable jacket can have a jacket vent notch disposed in a top surface of the deformable jacket. The bolt head and the jacket can have alignment indicator marks thereon. The bolt threads can have a variable pitch diameter.

摘要:
An alignment interlock for reciprocating tooling that includes a female lock having a central engagement area and a corresponding male lock having a profile shaped to matingly engage with the central engagement area. A plurality of particle rings are preferably formed on an engagement surface of the profile and an engagement ramp having a polished, radiused lead-in is preferably formed at a leading edge of the profile.
摘要:
An apparatus for releasing a part that has an undercut, particularly in an injection molding system. A flange is moveably mounted with respect to a moveable part of an injection mold. A head is moveably mounted with respect to the moveable part. A joint, such as a ball-and-socket joint, is used to connect the head with respect to the flange. The head has a shoulder that contacts a stop which is longitudinally fixed with respect to the moveable part, when the mold is in a closed position. A bias element can be used to normally urge the head in a lateral direction with respect to the moveable part.

A guiding mechanism and method are provided for properly aligning molds or portions thereof, such as ejector plates, as they are cycled. The guiding mechanism is an improvement over conventional bushings which require that the mold in which the bushings are mounted to be removed from the press and disassembled and thereafter, the press fitted bushings are pressed out. Herein, the bushings are provided with a replaceable insert or portion that is easily disconnected from the remainder of the bushing such as by unthreading a threaded insert from a threaded bushing body without removing the mold half from the press. A first replaceable insert can be mounted in the bushing body which is sized to receive the leader pin to guide the leader pins therein and align the mold halves as they are moved to the closed position. Alternatively, the inserts are mounted on the pins and are sized to be received in the bushings which guides the pins and inserts therein to align the mold halves or to guide the mold ejector plates for movement thereon. The first replaceable insert is replaceable with the a second insert of the same size as the first insert. The method of running a press includes the cycling of the mold halves until the pin or bushing inserts are worn, and then replacing the worn inserts by disconnecting them from the insert bodies and connecting new inserts to the insert bodies without removing the mold from the press or disassembling the mold halves.
