3 : 가동측형판 4 : 너트 고정핀3: movable side plate 4: nut fixing pin

20 : 인서트 너트20: insert nut

본 고안은 인서트 너트 삽입하여 작업하는 몰드금형에서 인서트 너트가 수지의 흐름방향에 상관없이 일정한 위치에 고정되도록한 장치에 관한 것이다.The present invention relates to a device in which the insert nut is fixed in a fixed position regardless of the flow direction of the resin in the mold mold to work by inserting the insert nut.

통상적으로 인서트너트를 내장하는 플라스틱 몰드물을 성행하기 위하여서는 터널게이트 또는 다이렉트 게이트의 방법을 사용하여 사출하는 방법을 사용하였으나 이러한 사출방법은 게이트의 선정에 제한요소가 많았으며 수지의 흐름방향에 따라 인서트 너트가 가이드핀에서 이동하는 경우가 종종발생하여 제품의 불량을 유발하는 요인이 되었다.In general, the injection molding method using tunnel gate or direct gate is used to perform the plastic mold containing the insert nut. However, this injection method has many limitations in the selection of the gate and according to the flow direction of the resin. The insert nut often travels on the guide pin, causing product defects.

이러한 요인을 해소하기 위하여 몰드물에 인서트너트를 삽입할 수 있는 공간을 확보한 후 사출성형후에 인서트너트를 압입하기 위하여 초음파를 이용하여 용접하는 방법이 강구되었으나 이러한 방법은 작업성이 매우 난해하여 생산성을 저하하며 제조원가가 상승되어 원가를 상승시키는 요인이 되었다.In order to solve these factors, the method of securing the space for insert nut inserts into the mold and welding by inserting the insert nut after injection molding has been devised. The manufacturing cost has risen and the cost has been increased.

본 고안은 상기와 같은 문제점을 해소하기 위하여 안출된 것으로서 사출성형시 인서트 너트가 이동하지 않도록 고정핀을 설치하여 인서트 너트가 수지의 흐름에도 견고하게 제위치를 견지하여 제품의 불량방샐을 미연에 방지하여 제품의 생산수율을 높일 수 있도록 함에 본 고안의 목적이 있다.The present invention was devised to solve the above problems, and the fixing nut is installed so that the insert nut does not move during injection molding, so that the insert nut keeps its position firmly against the flow of the resin, thereby preventing the product's defect prevention. The purpose of the present invention is to increase the production yield of the product.

상기 목적을 달성하기 위한 실시예를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.An embodiment for achieving the above object will be described in detail with reference to the accompanying drawings.

우선 첨부된 도면에 의거 본 고안의 구성들 설명하면, 사이드게이트금형에서 고정측형판(1)에는 가이드 핀(2)을 설치하여 인서트너트(20)를 임시고정할 수 있도록 하고, 가동측형판(3)에는 다수개의 너트고정편(4)을 설치하여 금형이 닫힐때 너트고정핀(4)의 단부가 인서트 너트(20)를 압압하여 인서트 너트(20)가 이동하지 못하도록 고정하여서 된것으로서 도면중 미설명 부호 11은 받침판, 10은 몰드물, 12는 스프로우, 13은 게이트, 15는 이젝트핀이다.First, according to the accompanying drawings, the configurations of the present invention will be described. In the side gate mold, the fixed side plate 1 is provided with guide pins 2 so that the insert nut 20 can be temporarily fixed, and the movable side plate ( 3) a plurality of nut retaining pieces (4) is installed so that the end of the nut fixing pin (4) is fixed to the insert nut (20) to prevent the insert nut (20) from moving when the mold is closed. Reference numeral 11 is a support plate, 10 is a mold, 12 is a sparrow, 13 is a gate, 15 is an eject pin.

이와같이 구성된 본 고안의 작용효과는 수지를 사용하여 인서트너트를 구비하는 몰드물(10)을 성행하고자 할때 고정측형판(1)에 설치된 가이드핀(2)에 인서트 너트 (20)를 끼워 가고정한 후 가동측형판(3)을 닫으면 가동측형판(3)의 전면보다 약간 돌축되게 설치되어 있으며 후면은 받침판(11)에 지지된 다수개의 너트 고정핀(4)이 인서트 너트(20)는 가이드핀(2)에 견고하게 고정되며 이와같은 상태에서 수지를 흘려주게되면 수지는 스프로우(12)를 지나 게이트(13)을 통해 내부로 흘러들어 형합물을 형성하게 되는데, 이때 수지의 흐름방향이 인서트 너트(20)를 고정측형판(1) 방향으로 밀어주는 방향으로 압력을 가하면서 충전하게되어 인서트 너트(20)를 고정측형판(1) 방향으로 압력을 가하면서 충전하게되어 인서트 너트(20)는 제 위치에 고정된 상태에서 형합물을 형성하게 된다.The effect of the present invention configured as described above is to temporarily insert the insert nut 20 into the guide pin 2 installed on the fixed side plate 1 when the mold 10 having the insert nut is used by using a resin. After closing the movable side plate (3) is installed slightly stiffer than the front side of the movable side plate (3), the rear is a plurality of nut fixing pins (4) supported by the support plate (11) insert nut 20 is a guide pin When the resin is firmly fixed to (2) and the resin is flowed in such a state, the resin flows through the gate 12 through the gate 12 to form a compound, and the resin flow direction is insert. The nut 20 is charged while applying pressure in the direction of pushing in the direction of the fixed side plate 1, and the insert nut 20 is charged while applying pressure in the direction of the fixed side plate 1 to the insert nut 20. Is fixed in place A is formed.

이와같이 형합물을 충진한 상탱서 온도를 낮추어 고형시킨후 가동측형판(3)을 후진시키면 형합물(10)은 인서트 고정핀(2)에 끼인상태에서 고정측형판(1)에서 벗어나게되며 이후 가동측형판이 후진을 계속함에 따라 이젝트핀(15)이 형합물을 외주면을 밀어주게 되므로 형합물은 인서트 너트 고정핀(2)에서 빠지게 된다.Thus, after lowering the temperature of the upper tanker filled with the mold to solidify, the movable side plate 3 is retracted, and the mold 10 is released from the fixed side plate 1 while being caught by the insert fixing pin 2, and then operated. As the side plate continues reversing, the eject pin 15 pushes the outer surface of the mold, so that the mold is removed from the insert nut fixing pin 2.

이와같은 과정에 의해 제조하고자 하는 형합물의 정위치에 인서트 너트를 형합시킬수 있게 된다.By this process it is possible to mold the insert nut in place of the molding to be produced.

상기한 바와같이 본 고안에 의하면 인서트 너트를 삽입하는 형합물을 사출함에 있어 인서트 너트가 금형내에서 요동없이 제자리에 고정되므로 사출물의 불량을 미연에 방지하므로 제조수율을 향상시킬 수 있다.As described above, according to the present invention, since the insert nut is fixed in place without fluctuation in the mold when inserting the insert nut, it is possible to improve the manufacturing yield since it prevents defects of the injection in advance.
