  • Patent number: 5238387
    Abstract: An apparatus for molding a product of synthetic resin which includes a mold assembly having a die plate and first and second mold dies which define a mold cavity therebetween. The first mold die includes a fixed member fixed to the die plate. At least two movable members are respectively displaceable in perpendicular directions away from each other. Each of the movable members are mounted on the die plate and are further displaced from the fixed member to open the first mold die. A resilient member is provided for perpendicular contacting the movable members and urging the movable members toward the fixed member to assembly the first mold die together.

  • Patent number: 5044919
    Abstract: An apparatus for molding a product such as an automotive instrument panel of synthetic resin has a first station including a mechanism for opening and closing a mold assembly, a second station including a mechanism for pouring a resin solution into the mold assembly which is closed, and a third station for hardening the poured resin solution in the mold assembly. A feed mechanism interconnects the first, second, and third stations in a looped configuration for circulating at least three mold assemblies through the first, second, and third stations. The mold assembly includes a first mold die for placing therein a covering sheet of a predetermined shape, a second mold die combinable with the first mold die to define a mold cavity therebetween, and a mechanism for pouring a resin foam solution into the mold cavity to form a molding integral with the covering sheet.

  • Patent number: 4872417
    Abstract: An automatic coating apparatus has a plurality of nozzle devices movable in X-, Y-, and Z-axis directions along tracks over a workpiece to be coated. One of the nozzle devices is displaceable with respect to the other nozzle device. Different coating materials are ejected from the nozzle devices toward the workpiece. Each of the nozzle devices has a nozzle which can be opened and closed by a valve operated by a cylinder mechanism. While a coating material is being ejected from one of the nozzle devices, the other nozzle device is closed. By thus selectively opening and closing the nozzle devices, the different coating materials can be coated successively on the workpiece.
