Abstract:
A method and apparatus for a nonsynchronous system for continuously molding articles from a material cured by the control of temperature and pressure. The apparatus includes a multi-section self-clamping mold, a controller system, a material injector, a transfer system, a curing apparatus for curing the articles, and a mold separator-assembler. The method comprises pre-treating and then assembling the mold in a clamped condition. Under the control of the controller system, the mold is then injected with material from the injector, and moved by the transfer system through the curing apparatus to cure the material within the mold. Once cured, the controller system moves the mold to the mold separator-assembler via the transfer system. The mold is then disassembled into sections, the molded article is removed, and the sections are pre-treated and reassembled, for the next injection operation.
Abstract:
A method and apparatus for removing molded articles from a continuous, nonsynchronous system using multi-section, self-clamping molds. The apparatus is a mold separator-assembler having an elevator, and a horizontal position mover for disassembling the mold into sections, tracks for receiving sections of the self-clamping molds, and a track mover for moving the mold sections along their respective tracks to parallel, co-planar work stations. Once the molded article is removed at one of the work stations using an intermediate mechanism, the main sections are pre-treated and then reassembled using a second elevator and second horizontal position mover, for the next injection operation.
Abstract:
An automated continuous manufacturing system which includes a rotatable work table having a plurality of work piece supports for maintaining work pieces during operation of said system, and a plurality of work stations for performing cleaning, pretreatment, treatment or assembly tasks on work pieces secured to said work piece supports. Each of the tasks performed at the work table is performed at a respective work station. Certain of the work stations comprise a removable station subassembly for performing a specific task. The removable station subassemblies are removably engagable with the rotatable work table and may be replaced with an alternate removable station subassembly for performing a desired alternate task. One of the work stations is an assembly station engaged with the rotatable work table for receiving work pieces from their individual work piece supports. The assembly station further includes a removing subassembly for removing the work pieces from the work piece supports for further assembly. An orientation subassembly is also provided with the assembly station, and is mounted adjacent the removing subassembly by a quick change release member to enable easy removal and replacement with an alternate orientation subassembly. The orientation subassembly includes a position sensor for detecting the position of an alignment member of a work piece.
Abstract:
An apparatus 10 for removing a mold section C from a molded part M. The apparatus 10 includes a base frame 11 supporting a driver 12 and a power supply, and a support member 16 for engagement with the molded part M. The driver 12 is engaged with and driven by the power supply M. The support member 16 has a clamping station for receiving and clamping the mold section C engaged with the molded part M. The clamping station 20 also has an open position for receiving the mold section C engaged with the molded part, and a closed position in which the mold section and molded part are clamped within the clamping station. The clamping station 20 further includes a heater 44, to assist with partial heating of the molded part M and mold section C prior to removal of the molded part. A removal station 22 for receiving the mold section C following removal from engagement with the molded part M is also provided, as is a force rod member 13 for engagement with the mold section, which is operated by the driver 12 for movement between the clamping and removal stations 20, 22 during removal of the mold section from the molded part.
