캡형의 금형제품(1)을 성형하고 이 제품의 일측에 홈부(2)를 형성하기 위하여 하부 금형틀(3)의 일측에 돌출부(4)를 형성하고 이 하부 금형틀(3)에는 다이캐스팅할 소재를 공급한 상태에서 상,하부 금형틀의 형합과 파팅으로 상기 제품을 제조하도록 함에 있어서, 상기 돌출부(4)의 내측에 모따기를 위한 경사부(5)를 형성하고 이 경사부(5)에 의하여 상기 제품의 단부에 모따기부(6)가 형성되면서 버가 발생되지 않도록 구성한 것이다.In order to mold the cap-shaped mold product 1 and to form the groove part 2 on one side of the product, a protrusion 4 is formed on one side of the lower mold frame 3, and the lower mold frame 3 is a material to diecast. In the manufacturing of the product by the molding and parting of the upper and lower molds in the state of supplying, the inclined portion 5 for chamfering is formed on the inner side of the protrusion 4 and by the inclined portion 5 The chamfer 6 is formed at the end of the product is configured so that no burr is generated.

이상과 같이 구성된 본 발명은 상기 캡형의 금형제품(1)을 성형하고 이 제품의 일측에 홈부(2)를 형성하기 위하여 하부 금형틀(3)과 상부 금형틀을 형합시킨 상태에서 이들의 사이로 다이캐스팅할 소재를 공급하고 이 소재를 성형하도록 한 것으로 상기 금형틀들이 형합된 상태에서 상기 소재가 공급되면, 상기 금형틀들의 형상에 따라 캡형의 제품이 성형되며, 상기 성형제품의 일측에는 상기 돌출부(4)에 의하여 홈부(2)가 형성되고, 상기 금형틀들의 파팅과 에젝팅작동에 의하여 상기 제품이 취출되면서 제품의 성형을 완료하게 된다.The present invention configured as described above die-casting between them in a state in which the lower mold mold 3 and the upper mold mold are molded in order to form the cap-shaped mold product 1 and to form a groove part 2 on one side of the product. When the material is supplied in a state in which the molds are joined, the cap-shaped product is molded according to the shape of the molds, and the protruding portion 4 is formed at one side of the molded product. Groove portion (2) is formed, and the product is taken out by the parting and ejecting operation of the molds to complete the molding of the product.

상기와 같이 캡형의 제품이 성형되고 이의 일측에 홈부(2)가 형성됨에 있어서, 상기 돌출부(4)의 내측 상단에 모따기를 위한 경사부(5)가 형성되어 있기 때문에상기 경사부(5)에 의하여 상기 제품의 홈부(2) 단부에 모따기부(6)가 형성되며 이 모따기부(6)에 의하여 상기 홈부(2)의 단부에서 버가 발생되지 않게 되는 것으로 상기 버의 형성에 따른 후가공이 필요없게 되는 것이다.When the cap-shaped product is molded as described above and the groove portion 2 is formed on one side thereof, the inclined portion 5 is formed on the inner upper end of the protruding portion 4 so that the inclined portion 5 is formed on the inclined portion 5. The chamfer 6 is formed at the end of the groove part 2 of the product, and the burr is not generated at the end of the groove part 2 by the chamfer 6 so that post-processing is required according to the formation of the burr. There will be no.

이상과 같은 본 발명은 상기와 같이 캡형의 제품을 성형하고 이의 일측에 하나 이상의 홈부를 형성함에 있어서, 상기 제품을 성형하는 금형틀의 돌출부에 경사부를 형성하고 이 경사부에 의하여 상기 제품의 단부에 모따기가 형성되도록 하므로써 상기 제품의 단부에서 버가 발생되지 않도록 할 수 있게 되며, 상기 버가 발생되지 않게 되므로 이 버를 제거하기 위한 후가공과 이를 위한 공정을 삭제할 수 있게 되고, 이에 따라 상기 제품의 성형을 원활하게 하면서 작업공수를 크게 줄일 수 있게 되는 점등의 특징을 지닌 것이다.In the present invention as described above, in forming the cap-shaped product and forming one or more grooves on one side thereof, the inclined portion is formed in the protrusion of the mold for forming the product, and the inclined portion is formed at the end of the product. By forming the chamfer, it is possible to prevent the burr from occurring at the end of the product, and since the burr is not generated, the post-processing for removing the burr and the process therefor may be eliminated, thereby forming the product. It has the feature of lighting that can greatly reduce the man-hour while smoothly.
