완구공의 제조방법How to make a toy ball

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

제1도는 본 발명의 단면도,1 is a cross-sectional view of the present invention,

제2도는 본 발명의 제조장치 예시도,2 is an illustration of a manufacturing apparatus of the present invention,

제3도는 본 발명의 성형장치가 닫힌 상태.3 is a state in which the molding apparatus of the present invention is closed.

Claims (1)

유압실린더(8)에 의하여 승강되는 압판(5)에 하형(2)를 장치하고 고정판(6)에 상형(3)을 장치하여 상형과 하형에 전기히터(4) (4a)를 접촉시키고 성형홈(2a)(3a)에 고무 50g, 경탄 50g에 발포제 8％와 살진산 4％를 넣어 혼합한 공소재(1가)를 넣고 형을 닫아 품온을 100-120℃로 15-20분간에 걸쳐 가열하므로써 내부에 들어 있는 소재(1가)가 발포되어 공중심부(1d)는 밀도가 적고 표층(1a)으로 갈수록 밀도가 크게 공을 형성시키는 완구공의 제조방법.The lower die 2 is mounted on the platen 5 lifted by the hydraulic cylinder 8, and the upper die 3 is mounted on the fixed plate 6 to contact the electric heaters 4 and 4a between the upper die and the lower die. (2a) Put the mixed material (monovalent) mixed with 50g of rubber and 8% of blowing agent and 4% of salmonic acid in 50g of rubber and hardwood, and close the mold and heat the product temperature at 100-120 ° C for 15-20 minutes. Therefore, the material (monovalent) contained therein is foamed, so that the air core (1d) is less dense, the density of the ball to the surface layer (1a) is a manufacturing method of the toy ball. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
