Claims (1)
합성수지 등으로 소정의 1차형틀(1)을 형성한 후 1차 형틀(1)에 스티렌계 수지와 발포제를 첨가하여 된 다공성 고분자 화합물을 소정량 주입한 후 발포시켜 표면이 평활된 1차 모형(2)을 다수개 형성하고, 규사, 지르콘, 크로마이트사의 모래 98.3중량 %와 결합제로서 페놀계수지를 0.8-1.2중량 % 및 무기산 또는 유기산 경화제 0.5-0.9중량 %를 혼합한 주물사(4)에 1차모형(2)을 매입한 다음, 매입된 1차모형(2)에 용융된 금속(액)(5)을 주입하여 1차모형(2)자체 구성 재질은 다공성 고분자 화합물을 용융금속(5)의 열로 열분해시켜 가스화하여 완성된 주물(6)을 형성하는 것을 특징으로 하는 주물 제조방법.After forming a predetermined primary mold (1) by using a synthetic resin or the like, a predetermined amount of a porous polymer compound obtained by adding a styrene-based resin and a blowing agent to the primary mold (1), and then foaming the primary model (smooth surface) 2) is formed, and primary casting sand 4 is formed by mixing 98.3% by weight of sand of silica sand, zircon and chromite sand with 0.8-1.2% by weight of phenolic resin and 0.5-0.9% by weight of inorganic or organic acid curing agent as a binder. After purchasing the model (2), the molten metal (liquid) (5) is injected into the embedded primary model (2), and the primary model (2) itself consists of a porous polymer compound of the molten metal (5). A method for producing a casting, which comprises thermally decomposing with heat to gasify to form a finished casting (6).※참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is to be disclosed based on the initial application.
