摘要:
A tool for forming an article in a forming operation is provided with a plurality of individually formed laminate sheets that are aligned, stacked and assembled to collectively form a tool body, each having a coefficient of thermal expansion. A series of the laminate sheets has a plurality of apertures coaxially formed therethrough. A plurality of pins collectively have a coefficient of thermal expansion and sized to be received within the plurality of apertures the plurality of pins extending through at least a plurality of the laminate sheets and collectively extend through the series of the laminate sheets. The coefficient of thermal expansion of the pins is higher than the coefficient of thermal expansion of the laminate sheets such that the laminate sheets and pins expand to secure the pins within the apertures to maintain the laminate sheets in stacked alignment while being heated to form the tool.

A mold block includes a tool body with a contoured finished surface adapted to receive a tool insert having a forming surface for forming a bottle neck in a molding operation. The tool body defines an internal channel for heat transfer with the forming surface. At least a portion of the channel is offset generally equidistant from the finished surface to provide a path contoured for conformal cooling of the insert. The tool body has a pair of ports intersecting the channel. Several methods for forming a mold block are disclosed and include machining a contoured finished surface adapted to receive a tool insert on a tool body, forming a heat transfer channel within the tool body, and forming a pair of ports into the tool body. At least a portion of the channel is offset generally equidistant from the finished surface for conformal cooling of the insert.

In one embodiment, a tool for forming an article in a molding operation has a tool body formed from a non-particulate material, with a particulate material bonded to the body. The body provides a forming surface for forming the article. The particulate material, or the particulate material and the tool body collectively provide a duct for conveying a fluid for transfer of heat with the forming surface. In another embodiment, the tool has a tool body formed from a non-particulate material with a cavity and the particulate material is disposed within the cavity. A heat transfer material is disposed in the cavity bonding the particulate material to the tool body. Methods for manufacturing such tools are also disclosed.

A tool 10 and a method for creating the tool 10 which is comprised of several selectively coupled sectional members 12, 16, and which includes at least one cooling channel 14. In one embodiment, each sectional member 12, 16, which is to be used to form the at least one cooling channel 14, has respective indented channels 18, 20. Channel 18 of member 12 registers with a unique one of the channels 20 of member 16 to which member 12 is coupled, thereby forming the unique cooling passage 14. Other embodiments are disclosed which also provide desired cooling paths 14.

An apparatus and a methodology 200, 350 for producing a tangible item 120 by the use of a plurality of sectional members, such as sectional members 10 and 14. In one embodiment, each sectional member 14 includes a protuberance 16 and these protuberances are selectively nestled to allow the various sectional members 14 to be connected and to cooperatively form a tangible item, such as tangible item 120. In an alternate embodiment of the invention, a first sectional member includes an opening 12 which receives a protuberance 70 from another sectional member. Other sectional members may thereafter be coupled to this assembly by the use of nestled protuberances, thereby allowing the coupled sectional members to cooperatively create a tangible item.
摘要:
A methodology 40 for producing a laminated tool 10 having desired dimensional accuracy. The tool 10 is produced by the use of several sectional members, such as sectional members 14, 16 which are selectively coupled and which are measured. The measurement is used to determine whether to selectively press these previously coupled sectional members 14, 16 to ensure that their coupled arrangement has a desired dimensional accuracy. Additional measurements and needed pressing operations are accomplished each time a new sectional member is added to the previously coupled sectional member combination.

An actuating means for a vehicle body closure latch includes a driver or passenger controlled electric motor driving a reciprocable rack through a gear train. The rack is resiliently biased to a neutral position and shifts an actuator from neutral to an operating position when the rack is moved from the neutral position to a driving position. The actuator is engageable with a latch operator to control movement of the latch bolt to unlatched position when the actuator moves to an operating position. When the actuator reaches the operating position, the actuator is positively stopped to stall the motor or power operator. When the power is removed from the stalled motor or power operator by the driver or passenger releasing a switch, the bias of the resilient centering means returns the rack to its initial neutral or starting position and back drives the motor through the gear train.

A lockable lift assist assembly includes a piston assembly moveable between an extended position and a retracted position. A valve assembly is coupled in movement together with the piston assembly. The valve assembly is configured to selectively alter a flow of a hydraulic fluid through a fluid communication path established within the valve assembly to control movement of the piston assembly.

A method 10 and a laminated tool 31 which is created by the method 10 and which is formed by the selective coupling or attachment of sectional members, such as members 14, 16. The formed tool 31 includes a finished surface 36 which is formed by the selective deposition of material 30 onto surface 22.
