  • Publication number: 20150115502
    Abstract: A collapsible core of an injection mold includes relatively movable components arrayed about an imaginary centerline. When in an operational position for molding a new product, the movable components each define a separate segment of the exterior of the core, such as side by side segments of interior features such as a continuous set of threads to be formed in a product being molded. To move between operational and retracted positions, some core components are pivotally connected to a nest of the core, and others are translatably connected to the nest. When a newly molded product is ejected from the mold, ejection movement causes the pivotally connected core components to pivot to disengage the newly formed interior features, and causes the translatably connected components to translate to disengage the newly formed interior features.

  • Patent number: 8342838
    Abstract: A mold includes upper and lower mold members, an upper-side slider pushing member, a slider, and an ejector rod. The upper-side slider pushing member is secured on the upper mold member. The lower mold member defines a movement space. The slider is slidably mounted on the lower mold member, and forms outer and inner angled surfaces. The ejector rod is movably mounted on the lower mold member. The ejector rod extends into the movement space and is driven by the push bar. The ejector rod and the upper-side slider pushing member are respectively engageable and thus pushing the inner and outer angled surfaces of the slider to cause the slider to slide on the lower mold member. The mold keeps the slider in a closed state while the mold is being opened, thereby preventing molded products from sticking to an upper mold member and saving internal space for the sliders.

  • Publication number: 20120318003
    Abstract: Disclosed are an ice maker, a refrigerator having the ice maker, and a method for supplying ice of the refrigerator. When the ice making container is rotated, ice of the ice making container freefalls to be released, thus reducing the size of the ice maker and making a refrigerator slimmer. Also, since a partition wall is not provided on an inner circumferential surface of the ice making container, the roughness of the inner circumferential surface of the ice making container can be enhanced, and accordingly, heat can be evenly transferred from an ice releasing heater to reduce a generation amount of residual water. In addition, since ice can be released without using the ice releasing heater, power consumption can be reduced and residual water which can be generated in case of using the heater can be further reduced.

    Abstract: A lightweight concrete mixture (e.g., comprising cement and polystyrene foam) is introduced into a compactable mold having a mold cavity defined by plural wall structures including at least two compacting wall structures. After introducing the lightweight concrete mixture into the compactable mold, the compacting wall structures are moved such that the lightweight concrete mixture is compacted in the mold cavity. The respective positions of the plural compacting wall structures can be maintained during curing of the lightweight concrete mixture such that the lightweight concrete mixture is held under compression during curing. A compactable mold may also include one or more tubes for forming tube-shaped cavities within a building block formed in the mold. Tubes can form intersecting cavities within the building block. Tubes can remain stationary while the compacting walls are moved, even when the tubes are attached to a compacting wall.
