이 고안은 사출성형기에 있어 사출성형된 제품을 손상시키지 않고 용이하게 인출시키기 위한 2단 금형의 제품 착탈구조에 관한 것이다.This invention relates to a product detachable structure of a two-stage mold for easy extraction without damaging the injection molded product in the injection molding machine.
통상 사출성형기는 형판전진→사출→계량→냉각→형판후퇴→압출의 1 싸이클과정을 거쳐 제품을 완성하고 있는 것이다.In general, an injection molding machine completes a product through one cycle of template advancement → injection → measurement → cooling → template retraction → extrusion.
또한, 제품을 용이하게 인출하도록 형판의 성형부에 실리콘수지나 피라핀과 같은 이형제를 도포시켜 사출성형된 제품이 형판의 성형부내에 달라붙지 않고 용이하게 탈락되게 하고 있다.In addition, a release agent such as silicone resin or pyramid is applied to the molding portion of the template to easily withdraw the product so that the injection molded product is easily detached without sticking to the molding portion of the template.
그러나, 종래에는 제1도와 같은 제품(1)을 사출성형한 후 제품을 취출할 때 제품의 상향돌출부(11)를 지지하여 주는 별도의 지지, 고정장치가 없으므로 제2도에 도시한 바와같이 캐비티코어(2 : Cavity core)가 열리면서 제품의 돌출부(11)가 성형부(21)에 끼여 잘 빠져나오지 않게되어 제품(1)을 손상시키게 되는 문제점이 있었다.However, in the related art, since there is no separate support and fixing device for supporting the upward protrusion 11 of the product when the product is ejected after injection molding the product 1 as shown in FIG. 1, the cavity as shown in FIG. As the core 2 opens, there is a problem that the protrusion 11 of the product is caught in the molding part 21 so as not to come out well, thereby damaging the product 1.
이 고안은 상기의 같은 문제점을 감안, 해결하기 위해 안출한 것으로서, 이 고안의 목적은 제품의 돌출부를 지지, 고정하여 주는 코어핀을 게재하여 제품 취출시 즉, 캐비티코어가 열릴때 돌출부를 지지, 고정하여 주므로서 제품이 손상되는 것을 방지하기 위한 2단 금형의 제품 착탈구조를 제공함에 있다.This invention has been devised to solve the above-mentioned problems, and the object of this invention is to provide a core pin for supporting and fixing the protrusion of the product to support the protrusion when the product is taken out, that is, when the cavity core is opened, In order to prevent damage to the product by fixing it to provide a product detachable structure of the two-stage mold.
상기 목적을 달성하기 위한 이 고안의 특징은, 캐비티코어 몸체의 수납부내에 스프링에 탄성지지되는 코어핀이 수납되어 캐비티코어가 열릴때 코어핀에 고정하고 있는 지지바의 끝단이 제품의 돌출부를 압입하며 상기 돌출부가 캐비티코어의 성형부에서 용이하게 탈락되도록 하여서된 점에 있다.A feature of this invention for achieving the above object is that the core pin elastically supported by the spring is accommodated in the receiving portion of the cavity core body so that the end of the support bar fixed to the core pin when the cavity core is opened presses the protrusion of the product. And the protrusion is easily detached from the molding portion of the cavity core.
이하, 이 고안에 따른 2단 금형의 제품 착탈구조의 바람직한 하나의 실시예에 대하여 첨부도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the product detachable structure of the two-stage mold according to the present invention will be described in detail.
제3도는 이 고안에 따른 일실시예도로서 제품의 성형부를 갖는 캐비티코어(3)의 몸체(31)에 코어핀(4)을 수납하는 수납부(32)를 형성하고, 상기 수납부(32)의 면(32a)에는 가이드홀(33),(34)을 각각 뚫고, 상기 가이드홀(33)은 캐비티코어 몸체(31)를 관통하며 가이드홀(34)은 성형부(35)에 연통되게 형성하고 있는 것이다.3 is an embodiment view according to the present invention to form an accommodating portion 32 for accommodating the core pin 4 in the body 31 of the cavity core 3 having a molded part of the product, the accommodating portion 32 Guide holes 33 and 34 are drilled in the surface 32a of the guide hole 33, the guide holes 33 penetrate the cavity core body 31, and the guide holes 34 are formed to communicate with the molding part 35. I'm doing it.
코어핀(4)은 캐비티코어(3)의 수납부내에 수용되어 캐비티코어(3)의 개,폐에 따라 제품(1)의 상향돌출부(11)를 지지하여 주도록 하고 있는 것으로서, 몸체(41)의 상,하부에 가이드바(42),(43)를 형성하여 가이드바(42)는 가이드홀(33)에 끼워지고 가이드바(43)의 외주연에는 탄성스프링(44)을 끼워 상기 탄성스프링(44)에 의해 코어핀(4)이 수납부내에서 탄성력을 갖도록 하고 있는 것이다.The core pin 4 is accommodated in the housing portion of the cavity core 3 to support the upward protrusion 11 of the product 1 in accordance with opening and closing of the cavity core 3. Guide bars 42 and 43 are formed at the upper and lower portions of the guide bars 42 so that the guide bars 42 are fitted into the guide holes 33 and the elastic springs 44 are fitted to the outer circumference of the guide bars 43. By 44, the core pin 4 has elastic force in an accommodating part.
가이드 홀(34)에는 지지바(5)를 삽입, 고정하고 있다.The support bar 5 is inserted and fixed to the guide hole 34.
이와같이 구성되는 캐비티코어(3)를 코어(6)에 올려놓게 되면, 가이드바(43)의 끝단(43a)이 코어(6)의 상단면(6a)과 접촉하면서 후동되어 스프링(44)을 압입하면서 코어핀 몸체(41)와 수납부의 면(32a) 사이에 일정한 갭(G)을 형성하게 된다.When the cavity core 3 configured as described above is placed on the core 6, the end 43a of the guide bar 43 is driven while contacting the top surface 6a of the core 6 to press-fit the spring 44. While forming a constant gap (G) between the core pin body 41 and the receiving surface (32a).
상기 갭(G)은 캐비티코어(3)가 코어(6)로부터 들어오릴게 될때, 즉 캐비티코어(3)를 열면 상기의 갭(G)만큼 스프링(44)의 탄성력으로 코어핀(4)의 지지바(5)가 성형부(21)에 의해 형성된 제품(1)의 돌출부(11)를 압압시켜 주도록 하여 주므로서 제품의 돌출부(11)가 성형부에 끼여서 취출시 제품이 손상되는 것을 방지하도록 하고 있는 것이다.The gap G is formed by the elastic force of the spring pin 44 by the gap G when the cavity core 3 is lifted from the core 6, that is, when the cavity core 3 is opened. The support bar 5 presses the protrusion 11 of the product 1 formed by the molding portion 21 so that the protrusion 11 of the product is caught in the molding portion to prevent the product from being damaged when taken out. I'm doing it.
이와같이 이 고안에 따른 2단 금형의 제품 착탈구조는 캐비티코어(3)의 성형부(21)에 제품의 돌출부(11)를 갖는 제품을 성형함에 따라 상기 제픔의 돌출부(11)를 압압하여 주는 지지바(5)에 의해 캐비티코어의 성형부내에서 제품의 돌출부가 쉽게 탈착하도록 하므로서 제품의 손상되는 것을 방지하여 생산성을 향상시키게 되는 이점이 있는 것이다.As described above, the product detachable structure of the two-stage mold according to the present invention supports to press the protrusion 11 of the product as the product having the protrusion 11 of the product is formed on the molding part 21 of the cavity core 3. The bar (5) has the advantage of improving the productivity by preventing the damage of the product by making it easy to detach the protrusion of the product in the molding portion of the cavity core.
