Description

사출물 게이트 절단장치{Projection gate cutting system}Injection gate cutting system

본 고안은 하나의 금형에서 다수의 사출제품이 수많은 러너(수지 용융액 중간 유입경로)게이트(수지 용융액 최종 유입경로)로 연결된 상태로 성형하는 사출공정과 성형된 사출물(다수의 제품, 러너, 게이트가 서로 연결된 상태) 중 제품과 직접연결된 폭이 좁은 게이트 부분을 절단하여 제품만을 추출해내는 게이트부 절단공정으로 이루어지는 통상의 사출성형공정에 있어서, 게이트부 절단 공정시 다수의 게이트부분을 한번에 일괄 자동절단 가능할 뿐 아니라 보다 깔끔하고 우수한 절단품질을 제공하여 생산성향상 및 품질향상, 작업환경개선 등의 이점을 제공하는 사출물 게이트 절단장치에 관한 것이다.The present invention is an injection process in which a plurality of injection products are connected to a number of runner (intermediate inflow paths of resin melt) gates (resin melt final flow path) in one mold, and a plurality of injection products (large number of products, runners, gates) In a conventional injection molding process in which a gate portion cutting process of cutting a narrow gate portion directly connected to a product and extracting only a product is performed, a plurality of gate portions may be automatically cut at a time during the gate portion cutting process. In addition, the present invention relates to an injection gate cutting device that provides advantages such as improved productivity, improved quality, and improved working environment by providing cleaner and superior cutting quality.

통상 휴대폰의 버튼이나 여타 소형 플라스틱 제품 및 각종 전자기기들의 합성수지제 소형 외장품, 악세사리 등의 제품들은 하나의 금형으로 다수의 제품을 성형사출하는 것이 일반적인 한편, 하나의 금형내에 다수의 제품을 한번에 사출성형하는 경우 각 배치된 제품간 용융재료의 이동 및 주입 중간경로인 러너가 구비되어야 함은 물론 그 러너의 끝부분과 제품간에는 폭이 좁은 최종 융용재료 유입경로인 게이트부가 필수적으로 요구된다.In general, products such as mobile phone buttons, other small plastic products, and small external articles made of synthetic resins and accessories of various electronic devices are generally molded and injected into a single mold, and a plurality of products are injected into one mold at a time. In the case of molding, a runner, which is an intermediate path for moving and injecting molten material between each arranged product, must be provided, as well as a gate part, which is a narrow final molten material inflow path, between the end of the runner and the product.

또, 금형틀에서 사출성형이 완료된 사출물(제품, 러너, 게이트부가 서로 연결된 상태)에 대해서는 후공정을 통해 제품과 연결된 게이트 부분을 절단하여 제품으로부터 러너와 게이트를 모두 제거하고 필요한 제품만을 깨끗하게 축출해 내는 게이트부 절단공정이 필수적일 뿐 아니라 제품의 품질유지 및 생산성을 고려해 게이트부 절단시 제품에 최소한의 흠집발생 및 신속한 절단작업이 또한 요구된다.In addition, for the injection molded parts (product, runner, gate part connected to each other) in the mold, the gate part connected to the product is cut through the post-process to remove all runners and gates from the product and to remove only the necessary products cleanly. Not only is the gate part cutting process essential, but also considering the maintenance of product quality and productivity, minimal scratches and rapid cutting work are required when cutting the gate part.

그러나 종래 게이트부 절단방법은 금형틀에서 제품와 러너, 게이트부가 서로 연결된 상태의 사출물을 인출한 후 그것을 한쪽 손으로 잡고 칼을 이용해 일일이 절단해내는 비능률적인 절단제거 방법을 취하고 있음에 따라 게이트부 절단에 따른 비용부단이 클 뿐 아니라 막대한 절단작업시간이 요구되는 등 가격경쟁력이 지극히 약화되는 문제점이 있었고, However, the conventional method of cutting gate parts is to cut the gate part according to the inefficient cutting and removing method of taking out the injection molding product and the runner and the gate part connected to each other from the mold mold and holding it with one hand and cutting it with a knife. There was a problem that the price competitiveness was extremely weakened, not only because the cost was excessive, but also enormous cutting time was required.

특히 칼로 게이트부를 자를 때 아주 사소한 부주의에 의해서도 외장품질이 특히 중요시되는 제품에 큰 흠집을 유발시켜 불량 및 품질저하로 이어지는 문제점이 있을 뿐만 아니라,In particular, when cutting the gate part with a knife, there is a problem that even a minor carelessness causes a large scratch on the product where exterior quality is particularly important, leading to defects and deterioration.

절단작업완료 후에도 추가적인 별도의 검사작업을 실시해야하는 불편함과 시간적 손실요소가 있었다.Even after the cutting work was completed, there were inconveniences and time loss factors that required additional inspection work.

나아가 위 같은 수작업 절단방법은 손으로 날카로운 도구를 이용함에 따라 부주의시 다칠 위험성까지 있고, 또 열악한 작업환경이 수반되어 작업장내의 청결도 유지 뿐 아니라 인력수급에도 큰 어려움이 야기되는 등 개선이 시급한 실정이다.In addition, the manual cutting method, such as the use of a sharp tool by hand, there is a risk of injuries inadvertently, and the poor working environment is accompanied by a poor working environment to maintain cleanliness in the workplace, as well as a great difficulty in supply and demand is urgently improved.

이에 본 고안에서는 상기와 같은 문제점을 일소하기 위해 안출한 것으로서, 먼저 다수의 제품와 러너,게이트가 서로 연결된 상태의 반 사출물을 용이하면서도 안전하게 안착시킨 후 제품에 흠집이 발생되지 않는 범위 각각의 게이트부 끝단 지점에 상,하 칼날이 자동으로 일괄 교차하게 하여 한번의 절단공정으로 러너, 게이트와 연결된 다수의 제품을 간단하면서도 신속하고 깨끗하게 축출해 낼 수 있는 그 절단장치를 제공함에 주안점을 두고 그 기술적 과제로서 완성한 것이다.Therefore, the present invention has been devised in order to eliminate the above problems, firstly, easy and safe seating of the semi-injection in a state in which a plurality of products, runners and gates are connected to each other, and then end of each gate part within a range where scratches are not generated in the product. Its technical task is to provide the cutting device that allows the upper and lower blades to cross automatically at the point automatically, and enables the simple and quick and clean removal of many products connected with runners and gates in one cutting process. It is completed.

위 기술적 과제를 달성하기 위해 본원에서는 첨부된 각 도면에 의거 보다 상세히 설명하면 하기와 같다.In order to achieve the above technical problem, the present disclosure will be described in more detail based on the accompanying drawings.

즉, 본 고안은 도 2에서 도시된 바와 같이 일정한 모양과 크기의 제품성형물(P)이 다수개 배열/형성된 가운데 그 제품성형물(P)들간에는 러너(10)와 게이트부(20)가 각각 연결된 상태인 게이트부 미절단 사출물(1)을 안전하게 안착/절단 셋팅할 수 있도록 하는 제품성형물 안착부(110)를 다수개소에 형성/배치시키며, 그 제품성형물 안착부(110) 사이에는 게이트 안내부(120)와 러너 수용공간(140)이 각각 마련된 게이트부 절단 하금형(100); That is, in the present invention, as shown in FIG. 2, a plurality of product moldings P having a predetermined shape and size are arranged / formed, and the runner 10 and the gate unit 20 are connected between the product moldings P, respectively. Forming and arranging the product molding seat 110 in a number of places that can be safely seated / cut setting the gate portion uncut injection (1) in the state, between the product molded seat 110, the gate guide ( A gate portion cut lower die 100 having 120 and runner accommodation spaces 140 respectively provided;

상기 절단 하금형(100)의 제품성형물 안착부(110)에 각각 하향 프레싱 될 수 있는 게이트부 절단 상금형(200); 을 상,하 대응 설치하는 것을 기본 구성으로한 가운데,A gate portion cutting upper mold 200 which can be pressed downward into the product molding seating portion 110 of the cutting lower mold 100; In the basic configuration to install the top and bottom

상기 게이트부 절단 하금형(100)의 구성요소 중 제품성형물 안착부(110)와 연결된 게이트 안내부(120)는 제품성형물 안착부(110)측과 접하는 부분에 칼날(131)이 형성되도록 하측 칼날용 경사각(130)을 각각 형성시킨 것을 핵심요지로 설계된 것이다.The gate guide portion 120 connected to the product molding seat 110 among the components of the gate cutting lower mold 100 has a lower blade so that the blade 131 is formed at a part in contact with the product molding seat 110. Forming the inclination angle 130 for each is designed as a key point.

그리고 상기한 구성 중 제품성형물 안착부(110)는 성형코자하는 제품(P)의 형태와 모양에 따라 다양하게 가공되는 것임은 물론 그 아래측으로 관통시켜 절단된 제품성형물이 아래로 용이하게 배출할 수 있게 하였으며,And the product molding mounting portion 110 of the above configuration is to be processed in various ways depending on the shape and shape of the product (P) to be molded, as well as the product molding cut through the bottom can be easily discharged down. To ensure that

또, 상기 제품성형물 안착부(110)측과 접하는 부분에 칼날(131) 형성된 하측 칼날용 경사각(130)은 제품에 흠집 등을 유발하지 않는 가운데 게이트부(20) 만을 아주 정밀하게 절단될 수 있도록 하는 것인 바, In addition, the inclined angle 130 for the lower blade formed with the blade 131 on the part in contact with the product molding portion 110 side so that only the gate portion 20 can be cut very precisely without causing scratches on the product. That is,

각도의 크기에 한정되는 것은 아니고 절단가능한 소정의 각도를 선택하여 적용하면 되는 것이다.The present invention is not limited to the size of the angle, and may be selected by applying a predetermined angle that can be cut.

그리고 상기 게이트부 절단 상금형(200)의 저면에는 제품성형물(P)이 직접 닿는 접촉부위인 만큼 필요에 따라 완충재(210)를 부착시켜 사용하면 보다 안전성을 기할 수 있다.In addition, the bottom surface of the gate portion cutting mold 200 may be attached to the product molded product P so that the cushioning material 210 may be attached as needed to ensure safety.

이와 같이 된 본 고안은 여러개의 제품성형물(P)이 연결/배치된 미절단 사출물(1) 전체를 안착시킨 후 한번의 하향 프레싱 동작으로 다수의 게이트부(20)를 동시에 절단가능하기 때문에 생산성을 보다 향상시킬 수 있을 뿐 아니라,The present invention thus achieved productivity since the plurality of gate parts 20 can be cut at the same time in one downward pressing operation after seating the entire uncut injection molding (1) to which a plurality of product moldings (P) are connected / arranged. Not only can you improve it,

특히 게이트부(20)를 안내하는 게이트 안내부(120)에 경사각(130)에 의한 칼날(131)이 형성되어 있음에 따라 제품성형물(P)과 게이트부(20)간 연결부를 아주 정밀하고도 깨끗하게 절단가능하여 아주 우수한 절단품질까지 제공된다.In particular, since the blade 131 is formed by the inclination angle 130 in the gate guide portion 120 for guiding the gate portion 20, the connection between the product molding (P) and the gate portion 20 is very precise and It can be cut cleanly and offers very good cutting quality.

이상과 같이 살펴본 본 고안의 사출물 게이트 절단장치는 다수개 제품이 배치된 게이트부 미절단 사출물 전체에 포함된 게이트부를 한번에 절단작업 가능하기 때문에 대량생산이 가능할 뿐 아니라 제품과 게이트부간 접지부를 아주 정밀하고도 깨끗하게 절단할 수 있어 절단품질유지에도 크게 기여할 수 있는 등 그 기대되는 바가 실로 다대한 고안이다.As described above, the injection gate cutting device of the present invention is capable of mass-producing the gate part included in the entire non-cutting injection part in which a plurality of products are arranged, so that not only mass production is possible but also the grounding part between the product and the gate part is very precise and It can be cut cleanly, and can greatly contribute to maintaining cutting quality.
