  • Patent number: 8968623
    Abstract: A method for demolding concrete blocks which are cast in a resilient mold supported in a rigid frame, the mold having a top surface and at least one cavity with an opening on the top surface, which cavity holds a cured cast concrete block. The mold has two opposing edges. The demolded blocks are stacked on a collection surface. A support is positioned over the cavity and the mold, the support and the frame are inverted and positioned in demolding apparatus. After two opposing edges of the mold are engaged by the demolding apparatus, the support is withdrawn to allow the mold to sag. The blocks may release from the mold and fall onto the collection surface. If any blocks remain in the mold, a plunger mechanism is pushed against the sagging mold to release the blocks. Guide members may facilitate positioning the blocks on the collection surface.

  • Patent number: 8877114
    Abstract: A method and apparatus for removing a SMP apparatus from within a cured composite part. The method may comprise the steps of triggering the SMP apparatus from a rigid state to a malleable state, inducing a pressure differential that drives the SMP apparatus, in the malleable state, away from the cured composite part and toward an inner mandrel tool, and removing the inner mandrel tool with the SMP apparatus resting thereon out of the cured composite part. The inner mandrel tool may comprise an outer surface having varying contours such that a surface area of the outer surface is great enough to prevent the SMP apparatus from folding over onto itself or creasing when driven toward the inner mandrel tool. A maximum straight line distance between points on the outer surface may be small enough to allow the inner mandrel tool clearance for removal from the cured composite part.

    Abstract: A method for dechucking a substrate from an electrostatic chuck (ESC) in a plasma processing system is provided. The method includes flowing a first gas into a plasma chamber. The method also includes flowing a second gas to a backside of the substrate to create a high pressure buildup of the second gas under the backside. The method further includes reducing a flow of the second gas such that at least a portion is trapped under the substrate backside. The method yet also includes pumping out the plasma chamber to increase a pressure differential between a first pressure that exists under the backside of the substrate and a second pressure that exists in a region above the substrate, wherein the pressure differential enables the substrate to be lifted from the ESC. The method yet also includes removing the substrate from the ESC.

The groove is connected, as by channels through the mold, to a switchable source for gas removal to prevent bubbles and for the application of pressurized gas to separate the mold and substrate. In use, the mold is disposed adjacent the moldable surface and gas is withdrawn from the patterned region through the groove as the mold is pressed toward and into the moldable surface. At or near the end of the imprinting, the process is switched from removal of gas to the application of pressurized gas. The pressurized gas passes through the groove and separates or facilitates separation of the mold and the moldable surface.

Generally, this molding method will involve using a mold with a core side and a cavity side. The mold is designed to mold a substrate when filled with the thermoplastic. A quantity of thermoplastic is injected into the mold. Once the plastic is in the mold, gas is vented to the core side of the mold as the thermoplastic cools. The gas is introduced via sintered vents that have been added to the mold. In general, the gas will have a pressure less than 500 psi. Once the thermoplastic cools, the substrate is formed and can be ejected from the mold.

    Abstract: A method of molding an inner or cover layer of a thermoset or thermoplastic material around a golf ball core within a compression mold, in which the core is positioned within a mold cavity containing preformed inner hemispherical shells and holding the opposing mold portions in a closed position wherein heat and pressure are applied. Knockout pins engage the core and layer to biasly eject it from the mold cavity, while simultaneously blowing high pressure air into the mold cavity to aid in releasing the core and layer without the need of a release agent coating the cavities.

  • Publication number: 20070278705
    Abstract: Contact lens delensing methods are described, and the present delensing methods include using a gas to facilitate separation of a polymerized contact lens product from a contact lens mold member. The contact lens mold member is compressed to deform a portion of the mold member, and gas, such as air, is directed toward the polymerized contact lens product in contact with the portion. The contact lens mold member can be compressed as the mold member, and lens product, rotate. A vacuum device can be used to separate the polymerized contact lens product from the contact lens mold member after compressing the portion of the mold member and directing the gas towards the mold member. Delensing systems used to practice the present methods are also described.

  • Patent number: 7255824
    Abstract: An apparatus for molding a plastic closure includes a male mold assembly including a forming pin and an outer pin sleeve which cooperate with a female mold for defining a mold cavity. To facilitate mechanical stripping of a molded closure from the forming pin, pressurized air is introduced into the molded closure through at least one air passageway which extends axially between the forming pin and pin sleeve. By outwardly expanding and forming the plastic closure during ejection from the forming pin, forces to which the closure is subjected during ejection are significantly reduced, thereby desirably reducing the amount of cooling of the closure that is required during the molding cycle prior to ejection. Significantly increased operating speeds for the compression molding apparatus can thus be achieved.

  • Patent number: 6875378
    Abstract: An optical disk molding apparatus and method are provided which prevent data formed on a molded object from being damaged and prevent quality deterioration of the molded object. There are provided a mold moving device, a first gas supply device, and a controller, whereby a first release space part is formed by opening molds from a mold clamp state by a movement distance not damaging a data transferred face of the optical disk, and a gas is supplied to the first release space part at a point in time when the first release space part is formed, thereby totally separating the optical disk and a stamper from each other. No damage is caused to a data transferred face at the point in time when the first release space part is formed. Since separation between the optical disk and the stamper is performed via pressure of the gas after the first release space part is formed, data is prevented from being damaged over the data transferred face of the optical disk in its entirety.
