DOUBLE EXTRUSION MOLDING DEVICE

摘要

PURPOSE: A double extrusion molding device is provided to form the surfaces of products as natural textures of wood and to prevent molding defectives. CONSTITUTION: A double extrusion molding device is composed of a main extruder for receiving first synthetic resin to continuously extrude products; a feeding pipe(51) of which an end is connected to the side of a mold disposed in front of the main extruder to extrusion-mold the products, installed to cross the main extruder; a wood powder inputting hopper(61) installed to the side of the feeding pipe to put second synthetic resin raw materials containing wood powders; a pigment inputting hopper(71) installed to the feeding pipe at the side of a wood powder inputting inlet to input a pigment; and a sub extruder(100) having a gas discharging outlet(81) disposed to the feeding pipe between the pigment inputting hopper and the mold to discharge gas generated in the feeding pipe. The feeding pipe includes a feeding screw(52) rotatively formed at the inside.
