븐 고안은 사출금형에서 합성수지재로 사출성형이 완료된 제품을 금형으로부터 취출하는 과정에서 발생되는 백화현상을 방지할 수 있도록 취출밀핀에 2차 취출하는 보조밀핀을 장치하여서된 사출금형의 제품 백화현상방지 취출장치에 관한 것이다.Even design prevents the product whitening phenomenon of the injection mold by installing the auxiliary mill pin to take out the second extraction pin to prevent the whitening phenomenon generated during the process of ejecting the finished product from the mold from the injection mold to the synthetic resin material. It relates to a taking out device.
종래의 경우 사출성형품의 제품특성에 따라 외관이 중요한 부분에 대해선 사출성형이 완료된 후 사출금형으로부터 제품을 이탈시키는데 있어 에젝터봉의 동작으로 밀판에 핀지지판으로 장치된 밀핀으로 하여금 성형품을 취출케되는데 이때 취출과정에서 밀핀과 성형품간에 취출에 필요한 취출력이 작용됨에 따라 제품에는 백화현상이 발생되는 결함이 있어 이를 방지키위한 취출장치로서는 핀지지판과 밀판사이에 일정길이의 핀을 장치하여 이용했으나 백화현상이 방지되는데 필요한 일정한 스트로크 조정이 어려운 결점이 있었다.In the conventional case, in the case where the appearance is important according to the product characteristics of the injection molded product, after the injection molding is completed, the ejector rod is ejected from the injection mold in order to take out the molded product by means of a pin pin installed on the plate as a pin support plate. As the ejection power required for ejection is applied between the mill pin and the molded product during the ejection process, the product has a defect of whitening phenomenon.As a ejection device to prevent this, a pin of a certain length is installed between the pin support plate and the mill plate. There was a drawback that the constant stroke adjustment required to prevent this was difficult.
따라서 본 고안은 이와같은 종래의 결점을 해소시키기 위해 밀핀의 상부에 탄력적으로 백화현상이 방지되는 스크로크로 대응할 수 있는 보조밀핀을 장치하여 된것으로서 그 실시예를 도시한 첨부도면에 따라 그 구성 및 작용효과를 상세히 설명하면 다음과 같다.Therefore, the present invention is to provide a secondary mill pin that can respond to the scratches to prevent bleaching elastically on the upper part of the mill pin in order to solve such a conventional defect as the configuration and according to the accompanying drawings showing the embodiment Detailed description of the effect is as follows.
에젝터봉(1)의 상향이동으로 핀지지판(2)을 통해 다수의 밀핀(3)이 장착된 밀판(4)이 상향이동하면서 하코어(5)의 상면에 위치한 사출성형품(6)이 밀핀(3)에 의해 취출되는 하부금형 장치에 있어서, 선정된 밀핀(3')의 상단부에 스프링(7)을 사이에 두고 연결핀(8)으로 보조밀핀(9)을 간극(a)이 형성되게 맞춤핀(10)을 통해 밀핀(3') 상단부에 체결하고, 보조밀핀(9)의 내부에서 간극(b)을 유지케 멈춤나사(11)를 조립하여서된 구성을 갖는다.The injection molded article 6 located on the upper surface of the lower core 5 is moved by the upward movement of the ejector rod 1 through the pin support plate 2. In the lower mold apparatus to be taken out by (3), a gap (a) is formed by the connecting pin (8) with the connecting pin (8) with a spring (7) interposed at the upper end of the selected mill pin (3 '). Fastening to the upper end of the mill pin (3 ') through the dowel pin 10, and has a configuration by assembling the stop screw (11) to maintain the gap (b) inside the auxiliary mill pin (9).
이와같이 구성되어진 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effect of the present invention configured in this way in detail as follows.
일반적인 사출금형장치에서 도면에 도시된 바와같이 사출성형하고자 하는 제품의 특성에 따라 외관이 중요한 부분에 대해 취출력이 작용되는 다수의 밀핀(3)중에 선정된 밀핀(3')의 상단에 적용하게 되는것으로서 성형품(6)의 취출동작으로 에젝터봉(1)이 상향으로 이동함에 따라 다수의 밀핀(3)이 핀지지판(2)을 통해 밀판(4)에 장치되어있는 상태의 밀판(4)이 이동함에 따라 성형품(6)이 안착되어있는 하코어(5)를 관통되면서 슬라이딩 용이케 조립된 밀핀(3)이 상향이동하므로서 다수의 밀핀(3)의 상면과 선정된 밀핀(3')의 상면이 성형품(6) 하면에 동시에 접지되면서 계속적인 상향이동할때 다수의 밀핀(3)에 의해서 성형품(6)은 1차적인 취출동작이 이루어지나 선정된 밀핀(3')의 상단에 조립된 보조밀핀(9)은 밀핀(3') 상면과 사이에 간극(a)을 유지케 장착된 스프링(7)을 압축하면서 보조밀핀(9)이 하향이동하여 이때 간극(a) 또는 간극(b)정도의 스트로크만큼 밀핀(3')이 이동하여 밀핀(3')의 상면과 보조밀핀(9)의 하면이 밀착 또는 연결핀(8)의 상단면과 멈춤나사(11) 하면이 밀착되었을매 선정된 밀핀(3')도 또다른 다수의 밀핀(3)과 2차적인 성형품(6) 취출동작을 하게되므로서 성형품(6) 취출시 밀핀(3)의 취출력에 의한 셩형품(6)의 백화현상 발생을 보조밀핀(9)의 장치로 2차적인 완충취출동작을 하게되어 백화현상을 방지하여 제품의 특성에 의해 외관이 중요한 것의 경우 그 부위에 해당하는 취출밀핀에만 본 고안의 보조밀핀(9)에 의한 백화현상방지 밀핀(3')을 적용하므로서 불량률을 최고화할 수 있게 된것이다.In the general injection mold apparatus, as shown in the drawing, it is applied to the upper end of the selected mill pin (3 ') among the plurality of mill pins (3) in which the ejection force is applied to the part whose appearance is important according to the characteristics of the product to be injected. As the ejector rod 1 is moved upward by the take-out operation of the molded article 6, the mill 4 in a state in which a plurality of mill pins 3 are installed on the mill 4 through the pin support plate 2 As the movement moves through the lower core 5 on which the molded article 6 is seated, the easily assembled mil pins 3 move upwards, and thus the upper surfaces of the plural mil pins 3 and the selected mil pins 3 '. When the upper surface is simultaneously grounded on the lower surface of the molded article 6, the molded article 6 is first taken out by the plurality of mil pins 3, but the auxiliary assembly assembled on the upper end of the selected mil pin 3 'is performed. The mil pin 9 is mounted to maintain a gap a between the mil pin 3 'top surface and As the auxiliary mill pin 9 moves downward while compressing the spring 7, at this time, the mill pin 3 'is moved by the stroke of the gap a or the gap b so that the upper surface of the mill pin 3' and the auxiliary mill pin 9 ), The lower surface of the contact pin or the upper surface of the connecting pin (8) and the stop screw (11) lower surface is in close contact with the selected mill pin (3 ') also take a number of other pins (3) and secondary molded article (6) When the molded article 6 is taken out, the whitening phenomenon of the X-shaped article 6 due to the ejection force of the mill pin 3 is secondary buffer take-out operation by the device of the auxiliary mill pin 9, thereby producing the whitening phenomenon. If the appearance is important by the characteristics of the product to prevent the whitening phenomenon by using the secondary mill pin (9) of the present invention only in the take-out mill pin corresponding to the site, it is possible to maximize the defective rate.
