다이캐스팅 금형구조체{ A die casting mold structure }Die casting mold structure

본 발명은 다이캐스팅 금형구조체에 관한 것으로, 더욱 구체적으로 설명하면, 가동금형부와 고정금형부로 구성되어 있는 다이캐스팅 금형구조체의 고정금형부상에 가동금형부의 해제시에는 가동금형부의 방향으로 압출되는 압출핀이 작동되게 탄성작동부가 형성되어 있어 다이캐스팅 금형구조체내에 주조되어 성형된 성형품의 배출을 압출핀의 탄성작동에 의하여 밀어낼 수 있게 되어 길면서도 성형이 어려운 가늘게 연장된 성형품도 손상이 없이 다이캐스팅 금형구조체에서 배출하는 것이 가능한 탄성작동부가 구비된 다이캐스팅금형 구조체에 관한 것이다.
The present invention relates to a die casting mold structure, more specifically, an extrusion pin extruded in the direction of the movable mold portion when the movable mold portion is released on the stationary mold portion of the die casting mold structure composed of the movable mold portion and the stationary mold portion. The elastic actuating part is formed so that it can be pushed out of the die-casting mold structure by the elastic action of the extrusion pin, so that even the long, difficult-formed molded product can be discharged from the die-casting mold structure without damage. The present invention relates to a die casting mold structure provided with an elastic actuator.

일반적으로, 도 1a,1b에 도시된 바와 같이, 수평으로 길게 연장되면서 수직으로 가지가 형성된 성형품은 주조후에 성형품(M)을 금형에서 배출하고자 할 경우에, 고정금형부(2)에서 고정된 성형품(M)의 상부로 연장된 가지부(m1)가 접착되어 용이하게 이탈되지 않게 되어 성형품(M)의 중앙부(M1)가 절곡되거나 하여 불량품이 발생되게 되는 우려가 많이 있었다.Generally, as illustrated in FIGS. 1A and 1B, a molded article vertically extended while being horizontally elongated is a molded article fixed at the stationary mold part 2 when the molded article M is to be discharged from the mold after casting. There were many concerns that the branch part m1 extended to the upper part of (M) could not be easily detached and be detached, and the center part M1 of the molded article M might be bent, and a defective product might arise.

이러한 가지부(m1)의 이탈을 용이하게 하기 위하여 가지부(m1)의 상부에 살붙힘구배(m11)를 주어 이탈이 용이하게 하며 하부에는 갈퀴핀에 의하여 강제적으로 인출되도록 언더컷붙힘(m12)을 형성시켜서 고정금형부(2)에서 성형된 성형품(M)을 인출시키게 하여 고정금형부(2)로부터 용이하게 이탈을 쉽게 하는 구조가 사용되고 있으나, 이러한 변형된 구조는 성형품의 중량이 증가되게 되어 고가의 원료가 많이 소요되게 되어 제조가가 증대되는 문제점이 발생되고 있으며, 더욱이 이러한 살붙힘구배(m11)나 언더컷붙힘(m12)의 결함을 제거하기 위하여 반드시 후가공이 필요하게 되므로 제조시간도 오래 걸리게 되고 제조원가가 높이지게 되는 문제점이 있었다.
In order to facilitate the detachment of the branch (m1) by giving a thinning gradient (m11) to the upper portion of the branch (m1) to facilitate the detachment and the undercut attachment (m12) to be forcibly pulled out by a rake pin at the bottom Formed to take out the molded article (M) formed in the stationary mold portion (2) to facilitate the departure from the stationary mold portion (2) is used, but this modified structure is expensive to increase the weight of the molded article It takes a lot of raw materials of the manufacturing cost is increasing, and furthermore, since the post-processing is necessary to remove the defects of the sticking gradient (m11) or undercut paste (m12) it takes a long time to manufacture There was a problem that the manufacturing cost is increased.

It consists of a double upper plate and the lower plate of the wheat plate (16).

상기 고정금형부(2)는 성형품(M)이 성형되는 고정금형성형체가 내부에 배치되는 금형공간(21a)이 형성되고 상기 금형공간(21a)에 이격되게 탄성작동공간(21b)이 형성된 고정금형본체(21)와, 상기 금형공간(21a)내에 배치되며 성형품(M)이 성형되는 형태가 형성된 캐비티(22a)를 갖는 고정금형성형체(22)와, 상기 캐비티(22a)에 성형된 성형품(M)을 압출시키도록 캐비티(22a)의 상부의 고정금형성형체(22)와 고정금형본체(21)에 연통되게 형성된 압출공(23)상에 삽입되어 작동되는 압출핀(24)과, 가동금형부(1)와 분리되게 작동하는 고정측 리턴핀(25)과, 상기 압출핀(24)과 고정측 리턴핀(25)을 탄성적으로 작동시키도록 탄성작동공간(21b)내에 설치되어 승하강되게 작동되는 고정측 밀판(26)과, 상기 고정측 밀판(26)을 승하강작동되게 탄성적으로 작동시키는 탄성작동부(27)를 포함한다. The stationary mold part 2 is a stationary mold in which a mold space 21a in which a stationary mold forming body for molding the molded article M is formed is formed, and an elastic working space 21b is formed to be spaced apart from the mold space 21a. A stationary mold forming body 22 having a main body 21, a cavity 22a formed in the mold space 21a and having a shape in which the molded article M is molded, and a molded article M molded in the cavity 22a. Extrusion pin 24 is inserted into and actuated on the extrusion hole 23 formed in communication with the stationary mold body 22 and the stationary mold body 21 in the upper portion of the cavity 22a to extrude), and the movable mold portion The fixed side return pin 25 which operates separately from (1), and is installed in the elastic operating space 21b so as to elastically operate the extruded pin 24 and the fixed side return pin 25 to be moved up and down. A fixed side plate 26 to be operated and an elastic actuating unit 27 for elastically operating the fixed side plate 26 to move up and down. .

본 실시예에서 상기 고정금형본체(21)는 금형공간(21a)과 탄성작동공간(21b)이 단일체로 형성된 구조이나, 제조가 용이하게 금형공간(21a)과 탄성작동공간(21b)이 분리되게 제조되어 나사와 같은 연결수단에 의하여 조립되는 것도 가능하다고 할 것이다.In the present embodiment, the fixed mold body 21 has a structure in which the mold space 21a and the elastic operation space 21b are formed as a single body, but the mold space 21a and the elastic operation space 21b are easily separated. It will be possible to manufacture and be assembled by a connecting means such as screws.

상기 고정측 밀판(26)은 상측 밀판과 하측 밀판의 2중으로 형성된 밀판구조를 갖는다.The fixed side plate 26 has a double plate structure formed of a double plate of the upper plate and the lower plate.

상기 탄성작동부(27)는 하부에 설치된 고정측 밀판(26)이 상기 가동금형부(1)의 방향으로 밀어내는 방향으로 힘이 가해지도록 탄성작동 되게 되어 성형품(M)이 성형되게 되어 경화되고 고정금형부(2)와 접하는 가동금형부(1)가 분리되면, 탄성작동부(27)가 작동되어 고정측 리턴핀(25)과 압출핀(24)이 작동되면서 캐비티(22a)내에 성형된 성형품(M)을 압출시켜 밀어내게 되므로 성형품(M)의 용이한 배출이 가능하게 작동되는 것이다.The elastic actuating part 27 is elastically actuated so that a force is applied in a direction in which the fixed side tight plate 26 installed in the lower part pushes in the direction of the movable mold part 1 so that a molded article M is molded and cured. When the movable mold part 1 in contact with the stationary mold part 2 is separated, the elastic actuating part 27 is operated so that the fixed side return pin 25 and the extrusion pin 24 are operated to be formed in the cavity 22a. Extruded molded article (M) is pushed out so that easy discharge of the molded article (M) is enabled.

상기 탄성작동부(27)는 고정측 리턴핀(25)을 작동시키는 우레탄 탄성부(27a)와 압출핀(24)을 작동시키는 스프링부(27b)로 구성되어, 고정금형부(2)와 접하는 가동금형부(1)가 분리되면, 탄성작동부(27)의 우레탄 탄성부(27a)와 스프링부(27b)가 탄성작동되는 방향으로 밀어내게 작동되므로, 상기 고정측 리턴핀(25)과 압출핀(24)이 성형품(M)을 상기 가동금형부(1)의 방향으로 밀어내는 방향으로 힘이 가해지므로 성형품(M)의 배출이 용이하게 되는 것이다.The elastic actuating part 27 is composed of a urethane elastic part 27a for operating the fixed side return pin 25 and a spring part 27b for operating the extrusion pin 24 to contact the fixed mold part 2. When the movable mold part 1 is separated, the urethane elastic part 27a and the spring part 27b of the elastic actuating part 27 are operated to push out in the direction in which the elastic actuation is performed. Since the force is applied in the direction in which the pin 24 pushes the molded article M in the direction of the movable mold part 1, the discharge of the molded article M is facilitated.

이와 같은 구성을 갖는 본 발명의 제1실시예에 따른 다이캐스팅금형 구조체(A)의 작동을 이하에 상세하게 설명한다.The operation of the die casting mold structure A according to the first embodiment of the present invention having such a configuration will be described in detail below.

우선, 다이캐스팅을 위하여 가동금형부(1)가 상기 고정금형부(2)로 가동되어 합체되고, 용탕이 금형성형체(12)의 캐비티(12a)와 고정금형성형체(22)의 캐비티(22a)내로 주입되어 경화되게 되면, 가동금형부(1)가 상기 고정금형부(2)로부터 분리되게 작동된다.First, the movable mold part 1 is moved to the fixed mold part 2 and coalesced for die casting, and the molten metal is brought into the cavity 12a of the mold molding 12 and into the cavity 22a of the fixed mold body 22. When injected and hardened, the movable mold part 1 is operated to be separated from the stationary mold part 2.

이와 같이, 가동금형부(1)가 상기 고정금형부(2)로부터 분리되게 작동되어 이격되게 되면, 고정금형부(2)의 탄성작동부(27)가 탄성작동되면서 탄성작동공간(21b)으로 하향이동하게 되고 따라서 압출핀(24)이 동시에 하향이동되면서 성형품(M)의 가지부(m1)를 밀어내게 되므로 성형품(M)은 용이하게 고정금형성형체(22)로부터 용이하게 이탈되게 되는 것이다.As such, when the movable mold part 1 is separated from the fixed mold part 2 and spaced apart, the elastic actuating part 27 of the fixed mold part 2 is elastically operated to the elastic operation space 21b. Since the extrusion pin 24 is moved downward at the same time to push down the branch portion (m1) of the molded article (M) at the same time, the molded article (M) is easily separated from the stationary mold (22).

이와 같이 성형품(M)이 가동금형부(1)로부터 용이하게 배출되게 되므로 다이캐스팅작업이 원활하게 수행되는 것이 가능하게 되는 것이다.
In this way, since the molded article M is easily discharged from the movable mold part 1, the die casting operation can be performed smoothly.

본 발명에 따른 다이캐스팅 금형구조체는 일반적인 금형제조산업에서 동일한 방식으로 반복적으로 사용하는 것이 가능하다고 할 것이므로 산업상 이용가능성이 있는 발명이라고 할 것이다.
The die-casting mold structure according to the present invention will be said to be an industrially applicable invention because it can be repeatedly used in the same manner in a general mold manufacturing industry.
