본 고안은 사출금형 장치에서 사출물의 고정장치에 관한것으로, 특히, 사출금형의 사출물 프로펠러팬, 냉각 팬(Fan)등의 중심부분에 금속와셔가 인써트(Insert)도면서 금속와셔(Washer)의 고정 및 평탄도를 유지시켜 사출물의 균형을 유지시키는 사출금형의 사출물 고정장치에 관한것이다.The present invention relates to a fixing device for an injection molding in an injection mold apparatus. In particular, a metal washer is inserted into a central part of an injection mold propeller fan, a cooling fan, etc. while fixing a metal washer. And it relates to an injection molding apparatus of the injection mold to maintain the flatness to maintain the balance of the injection molding.
종래의 경우에는 첨부된 도면 제 3 도 및 제 4 도와 같이 로케이트링(31)이 안착된 스프루부시(32)의 밑면부가 금속와셔(33)의 윗면에 면맞춤되고 금속와셔(33)에 하코어핀(34)이 삽입되어 금속와셔(33)를 사출물(35)의 중심부에 인써트 시킴으로써 금속와셔(33)의 고정이 불합리적이고, 사출물(35) 사출심 사출압에 의한 중심부위가 변형 및 휨에 의한 사출물의 중심부가 중심을 이루지 못함으로써 제품의 생산성 저하와 품질의 질이 떨어지는 등의 문제점이 있었다.In the related art, as shown in FIGS. 3 and 4, the bottom portion of the sprue bush 32 on which the locating ring 31 is seated is fitted to the top surface of the metal washer 33 and attached to the metal washer 33. The lower core pin 34 is inserted to insert the metal washer 33 into the center of the injection molding 35, which makes the fixing of the metal washer 33 unreasonable. Since the center of the injection molded product is not centered, there is a problem such as lowering the productivity of the product and the quality of the product.
이에 본 고안은 상기와 같은 종래의 문제점을 해결하기 위해 스프루 부시의 중심부 내부를 테이퍼(Taper)형으로 고정기구를 가공하여 하코어핀의 중심을 고정시키고, 내부 측면부에는 3면의 수지통로를 가공 형성하고, 하코어핀의 상단부에 단차가공으로 금속와셔를 고정 및 지지토록함과 밑면에는 접시 탄성부재를 설치하여 완충력을 완화시킬 수 있도록 안출된 것으로 첨부된 도면에 의거하여 구성 및 작용효과를 상세히 설명하면 다음과 같다.In order to solve the above problems, the present invention processes a fixing mechanism in a tapered shape to fix the center of the core of the sprue bush, thereby fixing the center of the core core, and having three resin passages on the inner side surface. It is made to form and to fix and support the metal washer by the step processing on the upper part of the lower core pin, and the plate elastic member is installed on the bottom to relieve the buffering force. It will be described in detail as follows.
사출금형의 사출물(1)을 고정시킴에 있어, 수지를 주입시키는 로케이트링(8)이 안착 고정된 스프루 부시(2)의 내부측면부에 3면의 수지통로(7)을 형성하고, 내부중심부에는 테이퍼형으로 고정구(6)를 가공하여 사출물(1)의 중심을 고정시키는 하코어핀(4)이 면맞춤 고정되게 형성하고, 상기 하코어핀(4)의 상단부에 금속와셔(3)의 고정지지토록 단차 가공하고, 하단부의 밑면에는 면맞춤부의 완충작용을 하는 접시 탄성부재(5)를 설치하여 구성되고, 상기 금속와셔(3)에 스프루와 와셔면의 면맞춤부인 고정부(9)를 형성시켜 구성된 것이다.In fixing the injection mold 1 of the injection mold, a resin ring 7 having three surfaces is formed on the inner side surface of the sprue bush 2 on which the locate ring 8 for injecting resin is seated and fixed, The lower core pin 4 for fixing the center of the injection-molded product 1 by forming a tapered shape to fix the center of the injection molded product 1 is formed to be fitted to the center, and the metal washer 3 at the upper end of the lower core pin 4. And fixing the stepped portion so as to support the fixed portion of the lower end of the bottom portion is provided with a plate elastic member (5) acting as a cushioning portion of the mating portion, the fixing portion that is the mating portion of the sprue and washer surface to the metal washer ( 9) is formed by forming.
이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
스프루부시(2)를 금속와셔(3)의 윗면 고정부(9)에 면맞춤하여 평탄도가 유지된 상태에서, 로케이트링(8)이 안착 고정된 스프루 부시(2)의 내부 중심부에 형성된 테이퍼형의 고정구(6)에 하코어핀(4)의 상단부를 삽입시켜 사출물(1)의 중심부를 고정시키고, 하코어핀(4)의 단차 가공부에 금속와셔(3)가 고정된 상태에서 로케이트링(8)을 통해서 수지를 주입시키면 스프루부시(2)의 내부 측면부에 3면으로 설치된 수지통로(7)를 통해 금속와셔(3)에 수지를 주입시켜 제품을 생산할 수 있다.The inner center of the sprue bush 2 on which the locating ring 8 is seated and secured while the sprue bush 2 is aligned with the upper surface fixing portion 9 of the metal washer 3. The upper end of the lower core pin 4 is inserted into the tapered fastener 6 formed therein, thereby fixing the center of the injection molded product 1, and the metal washer 3 fixed to the step machining part of the lower core pin 4. When resin is injected through the locating ring 8 in the state, the resin can be injected into the metal washer 3 through the resin passage 7 installed on three sides of the inner side of the sprue bush 2 to produce a product. .
한편, 상부의 금형이 닫힐때 과다한 압력에 의해 스프루부시(2)의 밑면과 하코어핀(4)의 면 맞춤시 하코어핀(4)의 밑면에 설치된 접시 탄성부재(5)에 의해 금속와셔(3)의 변형과 휨을 방지하여 제품을 생산하는 사출금형의 사출물 고정장치에 관한 것이다.On the other hand, when the upper mold is closed, the plate elastic member 5 installed on the bottom surface of the lower core pin 4 when the bottom surface of the sprue bush 2 and the lower core pin 4 is aligned with the metal by excessive pressure. An injection molding apparatus for an injection mold for producing a product by preventing deformation and warpage of the washer (3).
따라서, 본 고안은 스프루 부시(2)의 내부 측면부 3면에 수지 통로(7)가 설치되어 있어 수지의 공급을 원활히 할 수 있고, 하코어핀(4)의 상단부를 단차가공으로 금속와셔(3)의 고정지지가 용이하고, 하코어핀(4)의 밑면에 접시 탄성부재(5)가 설치되어 금속와셔(3)의 변형과 휨의 방지로 제품의 정밀성과 생산성을 향상시킬 수 있을뿐 아니라 제품의 품질을 향상시킬 수 있는 등의 효과를 얻을 수 있다.Therefore, the present invention is provided with a resin passage (7) is provided on the three inner side surface of the sprue bush (2) to facilitate the supply of resin, the upper end of the lower core pin (4) by the step machining of the metal washer ( 3) It is easy to fix and support, and the plate elastic member 5 is installed on the underside of the lower core pin 4, which can improve the precision and productivity of the product by preventing the deformation and bending of the metal washer 3. In addition, the effect of improving the quality of the product can be obtained.
