JPS6455206A - Frame for manufacturing imitation wooden pole and manufacture thereof - Google Patents

Abstract

PURPOSE:To make it possible to obtain a becomingly finished imitation wooden pole and at the same time eliminate the necessity for re-pasting pattern at every demolding of a product and consequently use a frame over a long period of time by a method wherein an imitation wooden pattern layer is formed by integrally insert-molding a perforated plate, which is mounted on the inner surface of a frame. CONSTITUTION:A perforated plate 2 such as woven metallic wire or the like is mounted by fixing materials 3 such as machine screws or the like on the inner surface of each one of an upper and a lover halved frames 1, which molds an imitation wooden pole by centrifuging. Under the state that the lower frame 1 is turned upside down, an imitation wooden master 5, on the surface of which an imitation wooden pattern is formed, is fitted to the interior of the turned frame 1 so as to keep the required gap between the master 5 and the inner surface of the frame 1, and then the periphery of the gap is tightly closed. After that, hardening material such as liquid rubber, liquid synthetic rubber or the like is poured from an inlet 6, which uses a bolt hole for mounting provided on the frame 1 or the like to the best advantage, in the gap made between the master and the inner surface of the frame 1, so as to fill the gap and harden itself. By demolding the imitation wooden master 5, an imitation wooden pattern layer 4, on the surface of which the imitation pattern is transferred, is molded under the state that the perforated plate 2 is insert-molded so as to be strongly bonded to the inner surface of the frame 1.
