  • Patent number: 10295754
    Abstract: A position determination method for determining a position of a point on a flat surface by observing the position of the point and a position of a fiducial portion on the flat surface in an image of a measuring system provided with an imaging optical system using coaxial episcopic illumination is provided. The fiducial portion is in the shape of a pillar at least in the basal portion and provided with an inclined surface surrounding the foot of the pillar. The method includes the steps of determining a position of the outer boundary of the foot from the boundary between the inclined surface and the flat surface in the image; determining the position of the fiducial portion from the position of the outer boundary of the foot; and determining the position of the point with respect to the position of the fiducial portion.

The mold is used for molding box bodies of at least two different of the packaging box for liquid crystal glass; A cavity(es) of the mold is of a joining structure, and comprises a group of shared splicing piece(s), and at least two groups of selected splicing pieces. The cavities formed by the shared splicing piece(s) and different groups of selected splicing pieces are in different sizes, and are respectively used for forming box bodies of different sizes. The mold can mold box bodies of at least two different sizes of the packaging box for liquid crystal glass. Because the shared splicing piece(s) can be shared, the development cost of the mold is lower than the cost of separately developing two sets of integrated box body molds. In addition, the development cycle can be shortened.

    Abstract: The side walls of a mold have recesses in each of which is mounted a mold core for forming depressions on the outer side of a concrete block which is to be produced in this mold. The mold cores are pivotally supported around a horizontal axis which is parallel to the mold walls on the outer side of the mold. A sloping cam slot on each mold core is used to pivot the mold cores into the mold cavity defined by the mold walls and then back into the recess. The inner edges of a recess closely fit the mold core and function as strippers which self-clean all surfaces of the mold core which have come into contact with the concrete when the mold core is pivoted back into its recess. As a result, time intervals for cleaning the mold cores are greatly lengthened and a clean and smooth surface of the finished concrete block is insured.

  • Patent number: 6740281
    Abstract: An integral three-dimensional article having interstitials therethrough, the three-dimensional article comprises an unconstrained number of axially successive stages. An apparatus and process for molding such a three-dimensional article are also disclosed. The apparatus has members extending into a mold cavity, each member having access to the periphery of the mold cavity. Each stage may nest within an adjacent stage. The nesting may be accomplished by having the end of one stage be convex, while the mating end of an adjacent stage is complementary and concave. The article may be useful as a static mixer, heat exchanger, etc.

  • Patent number: 6604930
    Abstract: A molding machine for a concrete mix includes a frame with a vibratible mold having a vertical through cavity with hollow cores extending downwardly in the mold cavity. A pallet receiver with a pallet thereon is movable upwardly to close the bottom of the cavity. Core tops have openings therein and ventilation pins are receivable to block air passage through the core top openings when the pallet is in mold closing position. Cups with bottom openings are in the cores below the top openings to receive and guide the pins and passageways around the pins permit suction-braking air to move past the pins to the cup bottom openings when the pins move downwardly away from the core top openings.

  • Patent number: 6485623
    Abstract: A device for forming angled wells in an electrophoresis gel slab includes a device having a plurality of projections oriented at an angle with respect to a longitudinal dimension of the device. A method for forming angled wells in a gel places the device in a gel forming material and allows the material to polymerize to form the electrophoresis gel slab. The device can be removed from the gel slab without distorting or tearing the gel and forming a plurality of substantially uniform sample wells oriented at an angle with respect to the edge of the gel slab. The sample wells are dimensioned to contain a liquid sample for electrophoresis separation. The gel slab can be rotated 90° so that the sample wells are oriented along a vertical edge of the gel slab with the sample wells retaining the liquid sample therein.

  • Patent number: 6471903
    Abstract: An array of hollow microneedles is constructed of molded plastic, in which a micro-machining technique is used to fabricate the molds used in a plastic microforming process. The molds are detachable and can be re-used. The preferred process for making the plastic arrays of microneedles is a microinjection technique. In the microinjection method, a molten plastic substance is injected between two micro-machined molds that contain microhole and micropillar arrays. Once the desired shape of the microneedle array has been formed, the mold and the plastic material are cooled down. Next, the molds are separated and the plastic microneedle array is detached from the mold structures.

  • Publication number: 20020134907
    Abstract: A method of forming a polymer-based microfluidic system platform using network building blocks selected from a set of interconnectable network building blocks, such as wire, pins, blocks, and interconnects. The selected building blocks are interconnectably assembled and fixedly positioned in precise positions in a mold cavity of a mold frame to construct a three-dimensional model construction of a microfluidic flow path network preferably having meso-scale dimensions. A hardenable liquid, such as poly (dimethylsiloxane) is then introduced into the mold cavity and hardened to form a platform structure as well as to mold the microfluidic flow path network having channels, reservoirs and ports. Pre-fabricated elbows, T's and other joints are used to interconnect various building block elements together. After hardening the liquid the building blocks are removed from the platform structure to make available the channels, cavities and ports within the platform structure.

  • Patent number: 6406654
    Abstract: A wax pattern mold and molding process are disclosed for forming a wax pattern of a hollow, thin walled object, in particular, a golf club head. A mold is provided in at least two halves defining a mold cavity. A core made up of a plurality of interfitted parts is placed in the mold to precisely define the thin walls. The core and mold are provided with a registration channel such that the core is properly registered in the cavity to ensure dimensional integrity of the thin walls. Pins, holes, slots, and fingers are provided to lock the core parts together while the wax pattern is formed and to permit the core parts to be disassembled through an opening in the mold without separating the mold halves.

  • Patent number: 6399006
    Abstract: A method and apparatus for producing molded fluoropolymer sweep elbows with straight threadable ends that minimizes distortion of the fitting. The apparatus comprises a mold core or insert that is comprised of multiple curved segments which are retracted from the mold individually. The mold core is divided into two or more pieces on a curved plane parallel to the curved central axis of the core and the segments thus formed are retracted from the mold by a combination of arcuate and translational motions to avoid distortion of the fitting ends.

  • Publication number: 20010040309
    Abstract: A method of forming a number of air vent holes in a rear case of a liquid crystal flat plate display (LCD) monitor and an apparatus therefor. The method includes forming a number of air vent holes on an incline plane of the rear case using a first metal mold and a second metal mold, such that pin holes are formed in the first metal mold and protrusion pins are installed in the second mold so as to be respectively inserted into the pin holes, to form respective air vent holes. The molding is performed in a state that the protrusion pins are inserted into the respective pin holes during injection of a solution which forms the rear case.
