몰드금형에서의 슬라이드코아 멈춤장치{slide core stop equipment in mold metalic}Slide core stop equipment in mold metalic

본 발명은 몰드금형 슬라이드코아 멈춤장치에 관한 것으로, 더욱 상세하게는 슬라이드코아 멈춤장치을 설치하여 금형적치 공간을 적게하고 안전사고를 방지하도록 한 몰드금형 슬라이드코아 멈춤장치에 관한 것이다.The present invention relates to a mold mold slide core stop device, and more particularly, to a mold mold slide core stop device to install a slide core stop device to reduce the mold loading space and to prevent safety accidents.

도 1 은 종래의 사출금형 슬라이드코아의 동작전 상태도이고, 도 2 는 종래의 사출금형 슬라이드코아가 스프링에 의해 후퇴한 상태도로서, 이를 참조하여 설명하면 다음과 같다.1 is a state diagram before the operation of the conventional injection mold slide core, Figure 2 is a state diagram of the conventional injection mold slide core retracted by a spring, as described with reference to this.

도 1 에 도시된 바와같이 몰드(mold)금형을 형합한 후 사출동작으로서 슬라이드코아(4)가 경사핀(3)에 의하여 스프링(9)이 압축된 상태이다.As shown in FIG. 1, the spring 9 is compressed by the inclined pin 3 of the slide core 4 as an injection operation after molding a mold.

도 2 에 도시된 바와같이 사출한 후 몰드금형이 제품을 취출하기 위하여 상원판(1)과 하원판(2)이 벌어져 제품 취출이 가능하다.After injection as shown in FIG. 2, the upper mold plate 1 and the lower plate 2 are opened in order for the mold mold to take out the product.

또한 몰드금형 슬라이드코아(4)를 작동시키기 위해서는 도 2 에 도시된 바와같이 브라켓트(6)에 볼트(7), 와셔(8), 스프링(9)을 끼운후 슬라이드코아(4)에 탭(tap)을 가공한 후 조립한다.In addition, in order to operate the mold mold slide core (4), as shown in Figure 2 by inserting the bolt (7), washer (8), spring (9) to the bracket (6) and then taps on the slide core (tap) ) And then assemble.

사출시 상원판(1), 하원판(2)을 형합한 플라스틱 수지로 성형을 한 후 상원판(1), 하원판(2)이 벌어지면 슬라이코아(4)가 스프링(9)에 의해서 후퇴한다.During injection, the upper plate 1 and the lower plate 2 are molded with a plastic resin, and after the upper plate 1 and the lower plate 2 are opened, the sleek core 4 is retracted by the spring 9. do.

종래에는 몰드금형 제작시 작업공정이 브라켓트, 스프링, 볼트, 탭 작업 등이나 또는 금형적치할 경우 2단,3단으로 쌓지 못하도록 적치공간이 넓어지고 옆으로 튀어나와 있기 때문에 안전사고와 금형관리에 문제점이 발생한다.Conventionally, when the mold mold is manufactured, the working process is bracket, spring, bolt, tap work, etc., or when the mold is placed, the stacking space is extended and protrudes to prevent the stacking into two and three stages. This happens.

따라서 본 발명은 상기한 종래의 문제점을 해결하기 위해 몰드금형 슬라이드 제작시 납기단축, 원가절감, 작업공정단축 및 적치공간을 적어지게 하고, 스프링이 옆으로 튀어나오지 않도록 하여 안전사고를 예방하고자 하는데 그 목적이 있다.Therefore, the present invention is to reduce the delivery time, cost reduction, work process shortening and storage space when manufacturing the mold mold slide to solve the above-mentioned conventional problems, and to prevent the safety accident by preventing the spring from protruding to the side. There is a purpose.

본 발명에 적용되는 몰드금형 슬라이드코아 멈춤장치는,Mold mold slide core stop device applied to the present invention,

브라켓트(6)에 볼트(5)(7), 와셔(8), 스프링(9)을 장착하고, 슬라이드코아(4)에 탭을 가공하여 사출시 상기 스프링(9)에 의해 상기 슬라이드코아(41)를 고정시키는 슬라이드코아(4) 멈춤장치에 있어서, 상기 슬라이드코아(4)에 취부된 맞춤핀(10)을 볼트(12)로 고정하고, 하원판(2)에 취부된 슬라이드코아멈춤장치(11)을 볼트(13)로 고정하며, 상기 하원판(2)의 일측면에 슬라이드코아멈춤장치(11) 홈(16)을 형성하여 사출시 상기 맞춤핀(10)이 경사핀(3)에 의해서 상기 슬라이드코아멈춤장치(11)에 삽입되어 상기 슬라이드코아(4)를 고정시킴을 특징으로 한다.Bolts (5) (7), washers (8), and springs (9) are mounted on the brackets (6), and the slide cores (41) are tabbed on the slide cores (4). In the slide core (4) stop device for fixing a), the slide core stop device attached to the lower plate (2) by fixing the dowel pin (10) attached to the slide core (4) with a bolt (12) 11) is fixed to the bolt (13), the slide core stop device (11) groove 16 is formed on one side of the lower plate (2) when the dowel pin 10 is inclined pin (3) during injection It is characterized in that it is inserted into the slide core stop device 11 to secure the slide core (4).

또한 슬라이드코아멈춤장치(11)에는 열처리된 환봉이 삽입되어 마모를 방지함을 특징으로 한다.In addition, the slide core stop device 11 is characterized in that the heat-treated round bar is inserted to prevent wear.

도 3 은 본 발명에 적용되는 슬라이드코아 멈춤장치의 동작전 상태도이고, 도 4 는 본 발명에 적용되는 슬라이드코아 멈춤장치의 동작후 상태도이며, 도 5 는 본 발명에 적용되는 슬라이드코아 멈춤블럭의 삽입부의 상세도로서, 이를 참조하여 설명하면 다음과 같다.Figure 3 is a state diagram before the operation of the slide core stop device applied to the present invention, Figure 4 is a state diagram after the operation of the slide core stop device applied to the present invention, Figure 5 is the insertion of the slide core stop block applied to the present invention As a detailed view of the negative, it will be described with reference to the following.

도 4 는 몰드금형이 제품을 사출하기 위한 동작으로서 맞품핀(10)이 슬라이드멈춤장치(11)의 홈(17)을 이탈한 상태를 나타낸 것이다.4 shows a state in which the mold pin 10 is released from the groove 17 of the slide stopper 11 as an operation for injecting the product.

사출 후 도 3 에 도시된 바와같이 하원판(2)에 슬라이드멈춤편(11)이 조립될 수 있도록 밀링 홈가공을 한 후 슬라이드코아(4)에 Φ10 맞춤핀(10)을 볼트(12)로 고정한 후 슬라이드멈춤장치(11)을 볼트(13)로 조립한다.After injection, milling groove processing is performed so that the slide stopper 11 can be assembled to the lower plate 2 as shown in FIG. 3, and then the Φ10 dowel pin 10 is attached to the slide core 4 with bolts 12. After fixing, the slide stopper 11 is assembled with a bolt (13).

몰드금형 사출시 슬라이드코아(4)의 맞춤핀(10) Φ10이 상원판(1)의 경사핀(3)에 의하여 슬라이드멈춤장치(11)의 폭 9.6mm에 강제로 끼워진 후 멈추므로 슬라이드코아가 윗쪽에 있을 경우에는 내려오지 않기 때문에 스프링 역할을 하게 된다.Since the alignment pin 10 Φ 10 of the slide core 4 is inserted into the width 9.6 mm of the slide stopper 11 by the inclined pin 3 of the upper plate 1 when the mold mold is injected, the slide core stops. If it is on the top, it does not come down, so it acts as a spring.

슬라이드멈춤장치(11)재질이 프라스틱으로 반복동작되므로 마모방지를 위하여 도 5 와 같이 Φ10 길이 8mm의 열처리 환봉(17)을 삽입하여 제작한다.Since the slide stopper 11 material is repeatedly operated by plastic, it is manufactured by inserting a heat treatment round bar 17 having a length of Φ10 8mm as shown in FIG. 5 to prevent wear.

몰드금형 제작시 사용되는 슬라이드멈춤장치(11)의 재질은 프라스틱으로 상원판(1)의 경사핀(3)의 작동으로 강제로 끼워지게 만든 탄력성 있는 프라스틱으로 만든 홈구조로 된 슬라이드멈춤장치(11)이다.The material of the slide stop device (11) used in the manufacture of the mold mold is a plastic slide stop device (11) made of elastic plastic, which is forcibly fitted by the operation of the inclined pin (3) of the upper plate (1). )to be.

좀더 부연하면, 상기 슬라이드멈춤장치(11)는 강제로 끼워지는 상기 홈(16)에서 마모 방지를 위해 Φ10 길이 8mm의 열처리 편(17)을 삽입하여 제작된다.More specifically, the slide stopper 11 is manufactured by inserting a heat treatment piece 17 of Φ10 length 8mm to prevent abrasion in the groove 16 to be forcibly fitted.

이상에서 설명한 바와같이 본 발명은, 몰드금형 제작시 슬라이드멈춤장치을 사용하면 브라켓트, 스프링지지 볼트, 와셔를 제작하지 않아도 되며, 이로인해 납기단축, 원가절감, 금형적치를 할 경우 외곽으로 튀어나오지 않으므로 적치공간이 줄어들고 안전사고를 미연에 방지할 수 있으며 금형관리를 효율적으로 할 수 있다.As described above, the present invention does not require the manufacture of brackets, spring support bolts, and washers when the slide stopper is used in the production of mold molds, and thus, when the delivery time is shortened, the cost is reduced, and the mold is not ejected outward, The space can be reduced, safety accidents can be prevented, and mold management can be efficiently performed.
