Abstract
PURPOSE: To facilitate the assured discharge of a formed product outside a die, in a resin scrapless forming method with pressurized air, by arranging product-discharge projecting pins inside a ring.
CONSTITUTION: A heated synthetic resin sheet cut piece is rolled between upper and lower platens 12, 14 and upper and lower rings 16, 18 into a rolled sheet 10 having a reversed tray-shape. Thereafter, the upper and lower platens 12, 14 are removed, and the upper ring 16 is then closed with a cover 52 while the lower ring 18 is closed with a forming die 54. In this state, the rolled sheet 10 is formed with pressurized air. In this device, a plurality of product-discharging pins 38 provided with U-grooved rings 40 at their top ends are arranged in the lower ring 18, in a manner such that the pins 38 are brought into contact with the outside edge part of the rolled sheet 10 and pushed up from the downside at the final forming step.
