본 고안은 폴리에치렌수지제 의자심판의 내구성이 좋고 비교적 저렴한 비용으로 만들 수 있는 의자심판 제조장치에 관한 것이다.The present invention relates to a chair core manufacturing apparatus which can make the chair core made of polyethylene resin with good durability and relatively low cost.
종래의 합성수지제 의자나 의자부속품은 주로 사출성형하여 만들어진 제품이므로 소재의 특성에 따라 제조금형이 비싸게 되어 경제성이 없었다.Conventional synthetic resin chairs and chair accessories are mainly manufactured by injection molding, so manufacturing molds are expensive according to the characteristics of the material, and thus, there is no economic feasibility.
특히, 내구성이 약하기 때문에 의자심판과 같은 내구성을 필요로 하는 제품을 만들 수 없는 문제점이 있었다.In particular, there is a problem that can not make a product that requires the durability, such as chair chair because the durability is weak.
본 고안은 이와같은 문제점을 해결하기 위하여 폴리에치렌수지제 판상 소재를 비교적 두꺼운 형태로 만들되 응고되기전에 의자심판 성형틀 사이에 넣고 유압으로 압착성형하여 의자심판을 제조할 수 있게 한 것으로 이를 첨부된 도면에 의하여 더욱 상세히 설명하면 다음과 같다.In order to solve the above problems, the present invention is made of polyethylene resin plate-shaped material in a relatively thick form, but before being solidified, it is inserted between the chair core molds and press-molded by hydraulic pressure to manufacture a chair core. When described in more detail by the drawings as follows.
제1도와 제2도는 본 고안의 제조장치를 나타낸 것으로 고정판(1)상면 네모서리 부분에 수직안내봉(3)을 각각 직립시켜 그 선단에 상판(2)을 고정시키고 상판 저면에 고정형틀(4)을 부착하되 이 고정형틀(4)은 내부에 냉각수저장실(401)이 구비되고 고정형틀(4) 저면을 의자심판 형상과 같은형으로 절개하여 그 내면의 일측에는 좌대외면형성부(402)를 만들고 타측에는 등받이외면형성부(403)를 형성하며 상판(2)하측에 위치한 유압실린더(5)의 피스톤로드(501) 선단에 승강판(6)을 장치하여 안내구멍(601)을 따라 승강작용케하고 승강판(6) 상면에 가동형틀(7)을 부착하되 이 가동형틀(7)은 내부에 냉각수저장실(701)이 구비되며 가동형틀(7)상면은 의자심판 내면과 같은 각도로 돌출부(705)를 형성하여 일측에는 좌대내면형성부(702)를 만들고 타측에는 등받이내면형성부(703)를 만들되 그 양측면에 각각 깊이가 깊은 측면 보강체형성홈(706)을 형성시킨 구성으로 결합구멍(다)을 가진 의자심판(가)의 좌대부(가1)와 등받이(가2)의 양측에 보강지지체(나)를 일체로 형성시킬 수 있도록 한 것이다.1 and 2 are views showing the manufacturing apparatus of the present invention, the vertical guide rods (3) upright on the four corners of the fixing plate (1), respectively, to fix the top plate (2) at its front end and the fixing frame (4) The fixed mold 4 is provided with a cooling water storage chamber 401 therein, and the bottom of the fixed mold 4 is shaped like a chair core. Cut into a mold to form a seat outer surface forming portion 402 on one side of the inner surface and a back surface forming portion 403 on the other side of the piston rod 501 of the hydraulic cylinder (5) located below the upper plate (2) The elevating plate 6 is provided to move up and down along the guide hole 601, and a movable mold 7 is attached to the upper surface of the elevator plate 6, and the movable mold 7 has a coolant storage chamber 701 therein. The upper surface of the movable mold (7) forms a protruding portion (705) at the same angle as the inner surface of the chair core to form the seat inner surface forming portion (702) on one side and the back surface inner forming portion (703) on the other side, the depths of which are respectively on both sides thereof. The reinforcing supporter (B) is integrally formed on both sides of the seat (1) and the backrest (A2) of the chair core (A) having a coupling hole (C) with a configuration in which the deep side reinforcement forming grooves (706) are formed. It is to be formed.
이와같이된 본 고안은 유압실린더(5)를 작동시켜 피스톤로드(501)선단에 장치된 승강판(6)을 승강시킴에 따라 가동형틀(7)을 고정형틀(4)에 접리시켜 그 연접부에 제품을 만들 수 있기 때문에 만들때는 승강판(6)을 하강시켜 놓은 다음 폴리에치렌수지제를 판상으로 만든 소재(9)가 응고되기전에 가동형틀(7)상면에형으로 덮어 씌운후 승강판(6)을 압상시키면 가동형틀(7)이 상승하여 고정형틀(4)의 형성부와 압접되어 폴리에치렌판상소재(9)는 의자심판(가)모습으로 압착성형되어 제품이 만들어지고 고정형틀(4)과 가동형틀(7)의 냉각장치에 의하여 성형품이 응고되어 의자심판(가)이 만들어지게 된다.According to the present invention, the movable mold 7 is folded to the stationary mold 4 by operating the hydraulic cylinder 5 to elevate the elevating plate 6 mounted at the end of the piston rod 501. Because the product can be made, the lifting plate (6) is lowered when making the product, and then on the upper surface of the movable mold (7) before the material (9) made of polyethylene resin plate After the cover plate is covered with a die, the lifting plate 6 is pushed up and the movable die 7 is raised to be pressed against the forming portion of the stationary die 4 so that the polyethylene-like plate material 9 is pressed against the chair core. The product is made and the molded product is solidified by the cooling device of the stationary mold 4 and the movable mold 7 so that the chair core a is made.
이렇게 본 고안의 제조장치로 만들어진 제품은 제3도 및 제4도와 같은 의자심판(가)을 얻게되어 단일공정으로 제품이 만들어질 뿐만 아니라 제품의 두께가 두껍게 되어서 내구적이고 튼튼한 심체를 만들수 있는 이점이 있으며 의자심판(가)의 좌대부(가1)와 등받이 (가2)의 양측에 보강지지체(나)가 일체로 형성되어 팔걸이 부착이 용이하고 좌대부(가1)와 등받이(가2)의 각도 변경이 없는 실용적인 제품을 저렴한 비용으로 제조할 수 있는 이점이 있는 것이다.Thus, the product made by the manufacturing apparatus of the present invention has the advantage of being able to obtain a chair core as shown in FIGS. 3 and 4, and not only to make the product in a single process but also to make the product thick and to create a durable and durable core. The reinforcement support (B) is integrally formed on both sides of the chair stand (A) and the backrest (A2) of the chair judge (A), so that the armrest can be easily attached and the seatrest (A) and the backrest (A2) There is an advantage that a practical product without an angle change can be manufactured at low cost.
