20090269434 | Injection mold friction puller - 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/or second first substantially hemispherical wedges having a first and/or 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. | 10-29-2009 |
20100221380 | Expandable cavity for injection molding tool - An injection molding tool having a first section moveable with respect to a second section. In a first position, the first section contacts the second section along a parting line and forms a cavity. An expandable cavity part is moveably mounted with respect to the second section. In a closed condition, the expandable cavity part is in a retracted or molding position. The expandable cavity part can be moved away from the molding position or the closed condition to a release position or an expanded condition with allows access to molded part or other article. A core pin is either moveably mounted with respect to the expandable cavity part or is in a fixed position with respect to the expandable cavity part. | 09-02-2010 |
20100320632 | ELECTRONIC CYCLE COUNTER - 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. | 12-23-2010 |
20100323054 | External plate locks for mold plates - A locking device for a mold including more than one movable plate. A spring-biased wedge block includes a first side wall and an opposing second side wall that is beveled with respect to the first side wall. A latch bar includes an inclined latch end for engaging with the second side wall of the wedge block. A cam bar includes a cam end for engaging with the first side wall of the wedge block. At least one of the wedge block, the latch bar or the cam bar is formed of a 4340 steel alloy, and at least one of the latch end, the cam end, or the wedge block second side wall is nitrided or nitride coated. | 12-23-2010 |
20110020490 | Demolding device for injection molding part with undercut - 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. | 01-27-2011 |
20110316180 | MOLD MONITORING - 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. | 12-29-2011 |
20120107442 | CUSTOMIZABLE MOLD SYSTEM - A customizable mold system for creating a custom mold by selecting from a plurality of pre-engineered mold bases and plates. Where the plurality of pre-engineered mold bases and plates provide various options for the custom mold including: a number of cavities; a size of the cavities; a type of coring method; and a type of gating method, for a selected global standard (US, DIN, JIS). | 05-03-2012 |
20120294968 | ALIGNMENT INTERLOCK FOR MOLDS AND DIES - 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. | 11-22-2012 |
20130103794 | SYSTEM AND METHOD FOR MONITORING TOOLING ACTIVITIES - An apparatus or system and method or process for displaying tool or die data or other tool or processing information on a display window of a webpage. A method for displaying tool data from a reciprocating tool includes positioning a monitor with respect to the reciprocating tool and the monitor recording data from the reciprocating tool. The data is communicated and then stored in a remote data storage location as stored tool data. The stored tool data is processed and then displayed, for example in the window of the webpage. | 04-25-2013 |
