Abstract

본 고안은 사출성형제품의 게이트 제거기에 관한 것으로서, 이를 더욱더 상세히 설명하자면 사출성형된 제품과 제품에 존재하는 게이트의 연결부를 상,하측부에서 한번에 제거가 가능하도록 한 것인데, 수평이동되는 절단부에 의해 게이트의 수평연결부를 절단하고 하고정판(1)과 실린더(21)가 수직으로 설치된 상고정판(2) 사이에 마련된 승강판(3)의 하강에 의해 게이트의 수직연결부를 절단할 수 있도록 되어 있으며, 승강판(3) 저면의 제품 고정대(33)가 제품(4)을 고정시킴으로서 게이트(5) 제거시에 발생될 수 있는 제품(4)의 흔들림을 방지하여 컷팅작업을 정교하게 할 수 있고, 또 수평, 수직의 이중으로 한번에 다수의 게이트 연결부(51,52)를 절단하므로 작업속도도 상승시킬 수 있기 때문에 게이트(5) 제거작업이 용이함은 물론 작업속도가 상승되어 생산성이 상승되고 생산비용은 감소되며, 컷팅되는 위치도 일정하여 게이트(5) 제거작업으로 인한 불량률도 낮출 수 있는 이점을 가진 유용한 고안인 것이다.The present invention relates to a gate remover of an injection molded product, and to explain this in more detail, it is possible to remove the connection part of the injection molded product and the gate existing in the product at a time from the upper and lower parts by a horizontal moving cutting part. The horizontal connection of the gate is cut and the vertical connection of the gate can be cut by the lowering of the elevating plate 3 provided between the fixed plate 1 and the upper fixing plate 2 in which the cylinder 21 is installed vertically. The product holder 33 on the bottom of the elevating plate 3 secures the product 4, thereby preventing the product 4 from shaking, which may be generated when the gate 5 is removed, thereby making the cutting work more precise. Since multiple gate connections 51 and 52 are cut at a time in a double horizontal and vertical manner, the work speed can be increased, so the removal of the gate 5 is easy and the work speed is increased. It is a useful design with the advantage that the acidity is increased, the production cost is reduced, and the cut position is also constant, so that the defect rate due to the gate 5 removal operation can be lowered.

Description

사출성형제품의 게이트 제거기{GATE REMOVAL MACHINE OF PRODUCTS FOR INJECTION MOLDING}GATE REMOVAL MACHINE OF PRODUCTS FOR INJECTION MOLDING

본 고안은 사출성형제품의 게이트 제거기에 관한 것으로서, 이를 더욱더 상세히 설명하자면 사출성형된 제품과 제품에 존재하는 게이트의 연결부를 상,하측부에서 한번에 제거가 가능하도록 한 것이다.The present invention relates to a gate remover of an injection molded product, and to explain this in more detail, it is possible to remove the connection part of the gate formed in the injection molded product and the product from the upper and lower portions at once.

일반적으로 사출성형시에는 얻고자하는 제품외에 용융된 원료가 금형으로 주입되는 주입로에 의해 생성되는 게이트도 함께 존재하게 됨으로 완성품을 얻기 위해서는 제품과 게이트의 연결부를 절단하여 게이트를 제거하여야 하는데, 제품과 게이트의 연결부는 금형에 따라 다수가 존재하고 연결부의 위치도 다양하여서,In general, during injection molding, the gate generated by the injection path into which the molten raw material is injected into the mold is also present in addition to the product to be obtained. Therefore, in order to obtain a finished product, the gate is removed by cutting the connection between the product and the gate. There are a large number of connections between the gate and the gate, and the location of the connection varies.

기존과 같이 수동으로 절단시에는 작업속도가 느리게 되는 문제점이 발생하고 있어 대량생산이 원할하지 못하고 생산성도 낮았으며, 절단부에는 흠집이 생길 수 있고 절단면이 깨끗하지 못함은 물론 균일하지 못하게 되는 문제점도 발생되고 있어 미관상 품질이 떨어지고 게이트 제거작업으로 인한 불량률이 높은 문제점을 안고 있는 실정이다.When cutting manually, there is a problem that the work speed is slow, so mass production is not desired and productivity is low. As a result, there is a problem in that aesthetic quality is deteriorated and defect rate due to gate removal is high.

본 고안은 위와 같이 종래에 제반되는 여러 문제점들을 한꺼번에 해결하기 위함에 그 기술적인 과제를 둔 것으로서, 특히 사출성형된 제품과 게이트를 연결하는 다수의 연결부를 수평과 수직의 이중으로 절단할 수 있도록 한 게이트 제거기를 제공함에 그 목적을 둔 것인데,The present invention has been made to solve the above-mentioned problems in the prior art at the same time, and in particular, it is possible to cut a plurality of connections horizontally and vertically, in particular, a plurality of connections connecting the injection molded product and the gate. The purpose is to provide a gate remover,

상기 컷터 지지대(114)는 컷터(115)를 제품 피난홈(116)의 양측에 고정하여서 이루어지고,The cutter support 114 is made by fixing the cutter 115 to both sides of the product evacuation groove 116,

상기 절단부(11)와 하고정판(1) 사이에는 스프링(118)을 가진 다수의 절단부 연결봉(117)을 마련하여서 된 것이다.A plurality of cutout connecting rods 117 having a spring 118 are provided between the cutout part 11 and the fixed plate 1.

이와 같이 된 본 고안은 제품 안착대(121)에 게이트(5)를 제거할 제품(4)을 안착시킨 후, 절단부(11)의 컷터 작동봉(113)을 작동시키게 되면 제품 피난홈(116)의 컷터(115)가 수평이동되면서 게이트(5)의 제1연결부(51)를 수평으로 절단한 후 컷터 작동봉(113)의 걸림턱(119)에 의해 제2연결부(52) 상측에 정지하게 되고,According to the present invention, the product evacuation groove 116 is operated when the cutter operating rod 113 of the cutting part 11 is operated after the product 4 is mounted on the product seating plate 121 to remove the gate 5. The cutter 115 is horizontally moved and the first connector 51 of the gate 5 is horizontally cut and then stopped above the second connector 52 by the latching jaw 119 of the cutter operating rod 113. Become,

이때 상고정판(2)의 실린더 작동봉(22)을 작동시키게 되면, 승강판(3)이 수직하강하여 승강판(3) 저면의 제품 고정대(33)가 제품 안착대(121)에 안착된 제품(4)을 흔들리지 않게 고정함과 동시에 컷터 지지대(114)의 상면을 하측으로 압박하여 절단부(11) 전체가 하측으로 압박되면서 제품 피난홈(116) 양측의 컷터(115)가 제2연결부(52)를 수직으로 절단하게 되며,At this time, when operating the cylinder operating rod 22 of the upper fixing plate (2), the lifting plate (3) is lowered vertically, the product fixing plate 33 of the bottom of the lifting plate (3) is seated on the product seating plate 121 While fixing (4) unshakably and simultaneously pressing the upper surface of the cutter support 114 downward, the entire cutting portion 11 is pressed downward, so that the cutters 115 at both sides of the product evacuation groove 116 are connected to the second connection portion 52. ) Will be cut vertically,

수평, 수직으로 절단된 후에는 절단부(11)가 그 하측의 스프링(118)으로 인해 압박되기전의 위치로 복귀됨과 동시에 승강판(3)도 상승하여 하강전의 위치로 복귀하게 되며 또 컷터 지지대(114)도 수평이동되기 전의 위치로 복귀하게 된다.After cutting horizontally and vertically, the cutting portion 11 is returned to the position before being pressed by the lower spring 118, and the lifting plate 3 is also raised to return to the position before the lowering and the cutter support 114 ) Will return to the position before horizontal movement.

또한 승강판(3)의 하강은 승강판(3) 양측의 안내관(31)이 상,하고정판(2,1)을 연결하는 연결봉(32)에 끼워져 있으므로 승강판(3)의 하강이 안정적으로 이루어지게 된다.In addition, the lowering of the elevating plate 3 is stable because the guide pipes 31 on both sides of the elevating plate 3 are fitted to the connecting rods 32 connecting the upper and fixed plates 2 and 1. Will be made.

따라서 본 고안은 승강판(3) 저면의 제품 고정대(33)가 제품(4)을 고정시킴으로서 게이트(5) 제거시에 발생될 수 있는 제품(4)의 흔들림을 방지하여 컷팅작업을 정교하게 할 수 있고, 또 수평, 수직의 이중으로 한번에 다수의 게이트 연결부(51,52)를 절단하므로 작업속도도 상승시킬 수 있기 때문에 게이트(5) 제거작업이 용이함은 물론 작업속도가 상승되어 생산성이 증가되고 생산비용은 감소되며, 컷팅되는 위치도 일정하여 게이트(5) 제거작업으로 인한 불량률도 낮출 수 있는 이점을 가진 유용한 고안인 것이다.Therefore, the present invention prevents the shaking of the product 4 which may be generated when the gate 5 is removed by the product holder 33 on the bottom of the elevating plate 3 so as to refine the cutting operation. In addition, since the gate speeds can be increased by cutting a plurality of gate connections 51 and 52 at once in horizontal and vertical, the removal of the gate 5 is easy, as well as the productivity is increased. Production cost is reduced, and the cut position is also a useful design with the advantage of lowering the defective rate due to the gate (5) removal work.
