Abstract
본 발명은 성형공간부내로 공급되는 수지의 흐름 방향으로 일정하게 하여 경계선(weld line)의 발생을 방지하는 저압 사출 성형 방법 및 성형 금형 장치를 제공하는데 발명의 목적이 있으며, 이를 위한 사출 방법은 상,하 금형 사이의 성형 공간부에 연결된 복수개의 게이트를 통하여 합성수지를 공급하여 플라스틱 제품을 성형하는 성형 방법에 있어서, 상기 복수개의 게이트를 순차적으로 개방시켜 수지를 공급하므로써 상,하 금형 사이의 성형 공간부 내를 공급된 수지가 일방향으로 흐르도록 공급함을 특징으로 하며 동 방법을 수행하기 위한 장치의 구성은 상,하 금형과 수지 공급의 메인 통로인 런너와, 런너로부터 분기되어 상,하 금형 사이의 성형 공간부에 연결되어 수지를 공급하는 복수개의 게이트를 구비하는 저압사출 성형 금형 장치에 있어서, 상기 복수개의 게이트에는 각기 통로를 선택적으로 개페시킬 수 있는 개페 밸브가 구비되어 있음을 특징으로 한다.An object of the present invention is to provide a low pressure injection molding method and a molding die apparatus for preventing the generation of a weld line by making it constant in the flow direction of the resin supplied into the molding space. In the molding method of molding a plastic product by supplying a synthetic resin through a plurality of gates connected to the molding space between the lower mold, the molding space between the upper and lower molds by sequentially opening the plurality of gates to supply resin It is characterized in that the supplied resin flows in one direction so that the configuration of the apparatus for performing the method is a runner which is the main passage of the upper and lower molds and the resin supply, and branched from the runners between the upper and lower molds. In the low pressure injection molding die device having a plurality of gates connected to the molding space to supply the resin, The plurality of gates are each provided with an opening valve for selectively opening the passage.
