Description

회전성형법에 의한 이중성형품의 내부 보강접합부 성형 장치Apparatus for forming internal reinforcement joint of double molded product by rotational molding method

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명의 금형내에 프라스틱 분말을 삽입한 상태 단면도.1 is a cross-sectional view of the plastic powder is inserted into the mold of the present invention.

제2도는 본 발명의 금형내면에 프라스틱 분말이 용융 부착된 상태 단면도.2 is a cross-sectional view of the plastic powder melt-attached to the mold inner surface of the present invention.

제3도는 본 발명의 금형을 서로 접근시켜 내면 돌출부의 용융 부착된 프라스틱이 서로 일체로 부착된 상태 단면도.3 is a cross-sectional view in which the molten plastics of the protrusions are integrally attached to each other when the mold of the present invention approaches each other.

Claims (2)

분말 회전성형법에 의하여 성형되는 이중성형품(12)의 내금형(4)과 외금형(5)의 내면에 각각 돌출부 (6),(6')를 돌설하여 통상의 회전성형법으로 성형하는 공정중 프라스틱분말(10)이 골고루 내, 외금형(4),(5) 내면에 용융 부착된 상태에서 설정된 간폭 만큼 양금형(4),(5)를 이동 접근시켜 양 돌출부(6).(6')의 용융프라스틱(11)이 접합된 다음 내, 외금형(4),(5)를 냉각시켜 이중성형품(12)에 내부 보강접합부(2)를 성형시키는 것을 특징으로 하는 회전성형법에 의한 이중성형품의 내부 보강접합부 성형방법.In-process plastic molding of projections 6 and 6 'on the inner surfaces of the inner mold 4 and outer mold 5 of the double-molded article 12 formed by the powder rotation molding method, respectively, and molding by the conventional rotation molding method. Both protrusions 6 and 6 are moved by moving the molds 4 and 5 by a predetermined width in a state in which the powder 10 is uniformly melted and attached to the inner surfaces of the molds 4 and 5. After the molten plastic 11 is bonded to the inner, the outer mold (4), (5) by cooling the double molded article by the rotational molding method, characterized in that for forming the internal reinforcement joint (2) to the double molded article (12) Method of forming internal reinforcement joint. 제1항에 있어서, 절곡 형성된 내, 외금형(4),(5)을 이동 접근시켜 양 돌출부(6),(6')의 용융프라스틱 (11)을 접합되게 하여 내부 보강접합부(2)가 형성되게 한 것을 특징으로 하는 이중성형품의 내부 보강접합부 성형방법.The inner reinforcement joint (2) according to claim 1, wherein the inner and outer molds (4) and (5) that are bent are moved to move the molten plastics (11) of both of the protrusions (6) and (6 '). Method for forming the internal reinforcement joint of the double-molded article, characterized in that formed. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
