Description

주철제 금형Cast iron mold

제1도는 본 고안의 단면도.1 is a cross-sectional view of the present invention.

제2도는 본 고안의 부분도.2 is a partial view of the present invention.

본 고안은 주로 철주물로 되는 아령, 바벨, 기계부품 등의 주물 제품을 제조하는 금형을 개량한데 특징이 있는 것이다.The present invention is characterized by an improved mold for manufacturing casting products such as dumbbells, barbells, and mechanical parts, which are mainly iron castings.

종래에는 주물사, 규산소다, 까스류 등의 재료를 사용하여 제품 1개당 일회용 사형(砂型)을 매회 1개씩 제조한 다음 철주물을 주입하여서 되었으며, 사형의 분쇄 및 페기처리를 하는 등, 제품의 탈사를 해야 하는 등의 작업 공정상 커다란 단점이 있었으며, 이와같이 하여서된 주물 제품은 표면이 거칠고, 곰보처럼 수가 생기므로 일반적으로 공지의 방법에 의하여 표면 가공 처리를 하여야 완제품이 되는 단점이 있었다.Conventionally, by using a material such as foundry sand, sodium silicate, and cutlets, one disposable sand mold is produced per product each time, and then iron casting is injected, and sanding is crushed and discarded. There was a big disadvantage in the work process, such as to have, and the cast product thus made has a disadvantage that the surface is rough, and the number is like a bear, so that the finished product is generally subjected to surface treatment by a known method.

본 고안은 이와같은 상기의 제결함을 고려하여 고온 강도에 우수한 오오스 테나이트계 및 회주철등의 주철을재료로 하여 주입로 상에 슬랙제거장치를 한 것으로 재질 FC-20의 바벨 플레이트를 예로들어 상세히 설명하면 다음과 같다.The present invention is made of a cast iron such as austenite-based and gray cast iron, which is excellent in high temperature strength in consideration of the above defects, and a slack removal device is formed on the injection path. The explanation is as follows.

고온 강도에 우수한 주철을 재료로 하여 주입구(1)은 두께 13-16미리미터, 폭은 두께의 4배, 깊이는 폭이상으로 하고, 압탕(10)은 수축공 소멸하기 위하여 50제곱미리미터×125미리미터 이상으로 하고, 바벨플레이트와의 겹침폭(7)(9)은 두께 2-3미리미터×75미리미터로 하여, 주입구(1)와 겹침목(7)과의 사이에 가능한 여러개의 슬랙제거장치(2,3,4,5)를 제2도와 같이 형성한 것이다.The inlet 1 is 13-16 millimeters thick, the width is 4 times the thickness, the depth is more than the width, and the hot water 10 is 50 square millimeters * in order to dissipate shrinkage pores. It should be 125 mm or more, and the overlap width (7) (9) with the barbell plate shall be 2-3 mm x 75 mm in thickness, and as many as possible between the inlet port (1) and the laminated clasp (7) The slack removal apparatuses 2, 3, 4, and 5 are formed as shown in FIG.

이와같이 하여서 된 금형을 섭씨 900도 정도를 예열한 후 동유 또는 모빌유에 탄소 또는 흑연 등을 섞은 액으로 표면 난열 처리를 하면 된다. 또한 슬렉 제거장치란 주입통로를 갑자기 좁혀지도록 하고 그 상부에 공간(2,3,4,5)를 형성하여, 비중이 가벼운 불순물 슬랙은 상부에 부딪혀 공간에 모이도록 한 것으로 이와같은 현상을 여러번 반복해서 불순물 슬랙을 제거할수 있도록 한 것이다.The mold thus prepared may be preheated to about 900 degrees Celsius, and then subjected to surface heat treatment with a mixture of carbon or graphite with copper or mobil oil. In addition, the slag removal device is to narrow the injection passage suddenly and to form a space (2, 3, 4, 5) on the upper part, so that the impurity slag with a light specific gravity hits the upper part and collects in the space. This is to remove impurities slack.

즉, 섭씨 1,340도 이하의 온도로 철주물을 가능한 빠른 속도로 주입하면 필요한 철주물위로 불순물 슬랙은 떠오르게 되는데, 이때 형성된 슬렉 제거장치(2,3,4,5)에 순차적으로 제2도에서와 같이 불순물 슬랙은 모이게 된다. 그러므로 필요한 철주물만 흐름이 급하지 않게 서서히 바벨 플레이트(8)에 주입하게 되며, 압탕(10)을 통하여 주입량을 확인할 수 있고, 수축율 및 수축공을 소멸할수 있도록 한 것이다.In other words, when the iron casting is injected as fast as possible at a temperature below 1,340 degrees Celsius, impurity slack rises on the required iron casting. In this case, the slag removal devices 2, 3, 4, and 5 are sequentially formed in FIG. Likewise impurity slack is collected. Therefore, only necessary cast iron is slowly injected into the barbell plate (8) so that the flow is not in a hurry, it is possible to confirm the injection amount through the pressure 10, and to shrink the shrinkage rate and shrinkage hole.

이와같이 본 고안을 이용하여 제조된 주물 제품은 냉간 주물 처럼 표면이 매우 강하고, 매끈하며, 곰보처럼 나타나는 수가 발생하지 아니함으로 공지의 방법에 의한 2차 표면 가공이 불필요한 완제품이 된다. 그러므로 본 고안은 종래의 사형(砂型)제작에 소모되는 시설비, 재료비, 인건비 등을 절감할수 있으며, 공지의 방법에 의한 2차 표면 가공이 불필요함으로 가공비 등이 절감되며, 본 고안의 금형 1개로 수만개의 제품을 제조할 수 있으므로 균일한 규격품(비중)을 제조할 수 있는 커다란 잇점이 있는 것이다.As such, the casting product manufactured using the present invention has a very strong surface, like a cold casting, and smooth, and does not appear as a bear, so that secondary surface processing by a known method is unnecessary. Therefore, the present invention can reduce the facility cost, material cost, labor cost, etc., which is consumed in the conventional sand mold production, and the processing cost, etc. are reduced by not requiring secondary surface processing by a known method, and tens of thousands of molds of the present invention It is possible to manufacture a product of, so there is a big advantage to produce a uniform standard (weight).

이러한 본 고안의 잇점을 주물 업계에서 이용한다면 주물 제품의 제조원가가 현저하게 절감될수 있으며, 시설 및 인원의 축소로 인하여 그 실용적 효과가 현저한 것으로 국가 경제 및 산업 발전에 커다란 도움이 될수 있을것 같다.If the advantage of the present invention is used in the casting industry, the manufacturing cost of the casting product can be significantly reduced, and the practical effect is remarkable due to the reduction of facilities and personnel, which may be a great help for the national economy and industrial development.
