摘要： An injection molding machine for producing shoe soles includes a fixed base, a turntable for rotation relative to the base between a plurality of stations, a plurality of molds including a mold piston and mold sides mounted on the turntable, the number of molds being equal to the number of stations, a multi-faceted column extending upwardly from and being rotatable with the turntable, and a last holder mounted on each face of the column, the number of last holders being equal to the number of molds. A dummy last is mounted on one side of the last holder for closing the mold by defining a first mold cavity with the mold sides and piston for molding a first sole portion at a first molding station, and a last is mounted on each of two opposing faces of the last holder adjacent the dummy last for receiving uppers and closing a mold defined by the mold sides, mold piston and first sole portion to mold a second sole portion between the first sole portion and the lasted upper at another molding station opposite the first molding station.

摘要： A method and apparatus for molding a rubber article from rubbers of two colors. Unvulcanized rubber is placed in a mold cavity. A movable mold member is advanced to spread and compress the rubber which is held in its spread condition until it is vulcanized. The movable member is provided with a peripheral outwardly extending lip for forming, in the rubber flash escaping around the periphery of the mold member, a peripherally extending weakened region. A peripherally extending recess region is also provided adjacent the lip for forming the flash rubber escaping past the lip into the base. After the first rubber has partially set and become vulcanized, the movable mold member is retracted away from the partially set rubber entrained therewith the bead formed in the recessed region thereof and thus tearing the rubber flash along the weakened region. The retraction of the movable mold member continues sufficient to expose a compressed gas inlet through which compressed gas is introduced to blow out through a gas outlet any particles of rubber which were formed during the severing of the rubber flash along the weakened region. After the mold cavity has been so cleaned, a second rubber is introduced into the mold cavity and the movable mold member is moved to spread the second injected rubber and to press it up against the partially set first injected rubber.

摘要： A machine for the production of footwear by injection molding comprises a multiplicity of shoe molds on a common carrier, such as a turntable, moving successively past a core-insertion station and an injection station. At the insertion station, a mold core in the form of a last is lowered into an open shoe mold which then moves into alignment with an extruder at the injection station. The lowerable core support at the insertion station carries a feeler which, by coming to rest on an aligned mold or on the mold carrier, limits the descent of the core into the mold.

摘要： A pneumatic-hydraulic control system for an apparatus for molding a shoe sole, in which a mold cavity is formed by a first fixed mold and a second mold movable relative to the first mold for opening and closing the mold cavity includes a mold operating cylinder with an operating piston movable therein, a piston rod connecting the operating piston to the second mold and a line connecting one side of the operating piston to a source of operating fluid for moving the second mold towards the first mold. A control cylinder with a control piston therein has one end in fluid communication with the operating cylinder and another end in fluid communication with the source of operating fluid, whereby the control piston moves in unison with the operating piston. A valve is provided in the line connecting the source of operating fluid to the operating cylinder for preventing the return of fluid to the reservoir from the operating cylinder when the second mold and operating piston are moving away from the first mold. An adjustable stop in the form of a knurled nut is connected to the piston rod of the control piston for limiting movement of such piston and consequently of the operating piston and the second mold away from the first mold.

摘要： When hot injection molding thermoplastic soles onto textile components the sole portion of the last is heated to achieve better bonding. In order to markedly increase production, only the peripheral part of the sole portion of the last is heated, the middle (remaining) part is maintained at an effectively lower temperature. This is accomplished by providing a last having either an insulating layer between the middle and peripheral parts thereof, or, marking the middle part entirely of insulating material.

摘要： A method for the production of an article of footwear or parts thereof from one or more molding materials, wherein the molding material is injected through a sprue hole into a two-part mold substantially surrounding a lasting member and having an enlarged opening spaced from the sprue hole. A plurality of closure members, each having a different molding surface on its interior, are sequentially aligned in sealing relationship to the opening to thereby permit molding of successive layers or portions of the article of footwear. A plurality of such molds and closure members may advantageously be mounted on a rotatable turret and successively presented to one or more stationary injectors.
