An apparatus for molding a part includes a plunger cavity, a plunger, and a mold cavity, wherein the plunger is oriented out-of-plane with respect to a major surface of the mold cavity, and first and second vents couples to respective first and second portions of the mold cavity. In a method, resin and fiber are forced into the mold cavity from a plunger cavity, and at least some of the fibers and resin are preferentially flowed to certain region in the mold cavity via the use of vents.

A tire curing mold comprises a plurality of vent holes provided on a side forming surface coming into contact with a side wall portion of a tire. The side forming portion is provided with a recess portion which is recessed toward an outer side in a tire width direction from a profile of the side forming surface. A diameter of a vent hole which is open within the recess portion is set to be larger than a diameter of a vent hole which is open on the profile of the side forming surface.

A microneedle chip and manufacturing method. The method comprises injecting, into a female mold, a fluid needle liquid, wherein forming cavities matching the shapes of needles of a microneedle chip are provided at the female mold and form a cavity array, injection inlets are provided at a surface of one side of the female mold, and air ejection openings are provided at a surface of another side of the female mold to form an air ejection surface; covering the air ejection surface of the female mold using a breathable film, and during injection, passing a gas through the breathable film so as to retain the liquid inside the forming cavities; curing the fluid needle liquid to form the microneedle chip, and demolding to obtain the same. By employing the air ejection openings and the breathable film, a liquid is retained while ejecting a gas, providing a favorable micro-injection effect.

To provide an injection mold capable of filling a necessary resin material for obtaining a desired molded article in a cavity space of a fine mesh structure, there is provided an injection mold according to an embodiment of the present invention composed of a core mold and a cavity mold, in which a cavity space is formed when the core and cavity molds are in a contact with each other, the cavity space surrounding a plurality of contact areas between the core and cavity molds. In the injection mold according to an embodiment of the present invention, at least one of the core and cavity molds has a through-hole which has an opening in a parting plane of the core and cavity molds and extends from the opening to an outside of the injection mold, the parting plane corresponding to the contact areas between the core and cavity molds.

A mold, a molding machine, and a foamed molded body manufacturing method are provided that are capable of more reliably preventing ingress of foamed resin into a gas discharge hole using a gas-impermeable member and capable of adequately discharging gas inside the cavity to the cavity outside through the gas discharge hole during foam molding, and that are also capable of achieving good design characteristics in a foamed molded body. A gas discharge hole 5 is provided at a cavity 4 inner face of a mold 1 and discharges gas inside the cavity 4 to outside the cavity 4. A gas-permeable member 6 is disposed inside the cavity 4 of the mold 1 so as to cover the gas discharge hole 5, and a gas-impermeable member 8 is disposed on the gas discharge hole 5 side of the gas-permeable member 6 so as to face the gas discharge hole 5. A portion of the gas discharge hole 5, spanning at least from axial direction intermediate portion of the gas discharge hole 5 to the cavity 4 side of the gas discharge hole 5, is configured with a tapered profile portion 5a that increases in diameter on progression toward the cavity 4 side.
