Description

수지제품 성형용 몰드Mold for molding resin products

본 고안은 수지제품 성형용 몰드에 관한 것으로, 좀 더 상세히는 몰드 내부에 삽입되어 성형된 수지제품을 변형이나 파손 없이 탈거할 수 있도록 구성한 수지제품 성형용 몰드에 관한 것이다.The present invention relates to a mold for molding a resin product, and more particularly, to a mold for molding a resin product that is inserted into the mold and configured to remove the molded resin product without deformation or damage.

도 1은 몰드에 반고체 상태의 수지제품이 삽입되기 전을 나타낸 사시도이고, 도 2는 몰드에 반고체 상태의 수지제품이 삽입된 후 클램프로 고정된 것을 나타낸 사시도이며, 도 3은 몰드 내부에서 고체 상태가 되며 성형된 수지제품을 탈거한 것을 나타낸 사시도이다.1 is a perspective view illustrating a resin product in a semi-solid state before being inserted into a mold, and FIG. 2 is a perspective view illustrating a clamped state after a semi-solid resin product is inserted into a mold, and FIG. 3 is a solid state in the mold. Is a perspective view showing that the molded resin product is removed.

도시한 바와같이 우레탄 폴리프로필렌 FRP와 같은 재질을 성형하여 제품을 만드는 몰드(10)는 상판(11)과 하판(12)으로 형성되고, 상판(11)과 하판(12)이 접하는 접합면 중간 부위에 제품의 형상과 같은 홈(13,14)이 상하로 나뉘어 상판(11)과 하판(12)에 형성되며, 상기 몰드(10)에 수지제품(16)을 성형할 경우에는 우선 수지제품(16)의 분리가 용이하도록 홈(13,14)에 이형제 처리를 하고, 상판(11)과 하판(12)의 홈(13,14)에 반고체 상태의 수지제품(16)을 삽입한 후 상기 상판(11)과 하판(12)에 클램프(15)로 고정하여 서로 밀착 고정한 다음 반고체 상태의 수지제품(16)이 고체 상태로 경화되는 일정 시간이 경과한 후에 상판(11)과 하판(12)을 해체한 후 홈(13,14)에 삽입된 고체상태의 수지제품(16)을 탈거하면 된다.As shown, a mold 10 for forming a product by molding a material such as urethane polypropylene FRP is formed of an upper plate 11 and a lower plate 12, and an intermediate portion of the joint surface at which the upper plate 11 and the lower plate 12 contact each other. The grooves 13 and 14, which are the same as the shape of the product, are divided into upper and lower portions, and are formed in the upper plate 11 and the lower plate 12. In the case of molding the resin product 16 in the mold 10, the resin product 16 The mold release agent is treated in the grooves 13 and 14 to facilitate separation, and the resin product 16 in the semi-solid state is inserted into the grooves 13 and 14 of the upper plate 11 and the lower plate 12 and then the upper plate ( 11) the upper plate 11 and the lower plate 12 are dismantled after a fixed time elapses after fixing the clamp 15 to the lower plate 12 and tightly fixing each other and then curing the semi-solid resin product 16 in a solid state. Then, the resin product 16 in the solid state inserted into the grooves 13 and 14 may be removed.

그러나 이와 같은 종래에 몰드(10)에서 고체 상태의 수지제품(16)을 탈 거하다 보면, 상판(11)과 하판(12)의 홈(13,14)에 이형제 처리를 한다 하더라도 수지제품(16)의 경화시 홈(13,14)과 수지제품(16)이 부분적으로 접착되는 경우가 많아 수지제품(16)의 탈거가 용이하지 못하고, 홈(13,14)에 밀착 삽입된 수지제품(16)을 무리하게 분리하다 보면 수지제품(16)이 변형되거나 파손되는 문제점이 있었다.However, when the resin product 16 in the solid state is removed from the mold 10 as described above, the resin product 16 is processed even if the release agent treatment is performed on the grooves 13 and 14 of the upper plate 11 and the lower plate 12. ), The grooves 13 and 14 and the resin product 16 partially adhere to each other when the resin is hardened, so that the resin product 16 may not be easily removed, and the resin product 16 closely adhered to the grooves 13 and 14. If you forcibly separate) there was a problem that the resin product 16 is deformed or broken.

본 고안은 전술한 바와 같은 종래에 몰드와 수지제품의 분리시 발생되는 문제점에 착안하여 제안된 것으로, 수지제품을 몰드에서 분리할 경우 변형이 파손이 발생되지 않도록 구성한 수지제품 성형용 몰드를 제공하고자 하는 것이다.The present invention has been proposed in view of the problems occurring in the separation of the mold and the resin product in the prior art as described above, to provide a mold for molding a resin product formed so that deformation does not occur when the resin product is separated from the mold. It is.

본 고안의 특징에 따르면, 상판(11)과 하판(12)으로 형성되며 서로 접하는 접합면에 각각 제품형상의 일부분이 되는 홈(13,14)이 형성된 몰드에 있어서, 상기 홈(13,14)에 연통되도록 상판(11)과 하판(12)에 형성한 유도공(17)과, 상기 유도공(17)에 탈착되며 압축공기를 홈(13,14)에 유입하는 공기유입관(19)과, 상기 유도공(17)을 메우며 탈착되는 마감용볼트(18)가 포함된 것을 특징으로 하는 수지제품 성형용 몰드가 제공된다.According to a feature of the present invention, in the mold formed with the upper plate 11 and the lower plate 12 and grooves 13 and 14, which are part of the product shape, respectively, on the joining surfaces in contact with each other, the grooves 13 and 14 An induction hole 17 formed in the upper plate 11 and the lower plate 12 so as to be in communication with the air, an air inlet pipe 19 which is detached from the induction hole 17 and introduces compressed air into the grooves 13 and 14; Provided is a mold for molding a resin product, which comprises a finishing bolt 18 which fills the guide hole 17 and is detachable.

이하에서 도면을 참조하여 본 고안의 바람직한 실시예를 설명한다.Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention.

도 4는 본 고안의 실시예를 나타낸 사시도이고, 도 5는 본 고안의 실시예를 나타낸 단면도이다. 도시한 바와같이 본 고안에 따른 수지제품 성형용 몰드(100)는 제품형상의 홈(13,14)이 형성된 상판(11)과 하판(12)에 원형의 유도공(17)을 홈(13,14)과 연통되게 형성하고, 상기 유도공(17)의 내부에 나사산(17a)을 형성하며, 상기 유도공(17)에 마감용 볼트(18)를 체결하여 유도공(17)을 메우도록 형성한다. 또한, 상기 유도공(17)의 나사산(17a)에 체결되도록 일측에 나사부(19a)가 형성되며 타측에 압축 공기를 배출하는 호스(20)와 결합되는 단면 원형상의 공기주입관(19)을 별도로 구비한다.4 is a perspective view showing an embodiment of the present invention, Figure 5 is a cross-sectional view showing an embodiment of the present invention. As shown, the mold 100 for molding a resin product according to the present invention has a circular guide hole 17 formed in the upper plate 11 and the lower plate 12 in which the grooves 13 and 14 of the product shape are formed. It is formed in communication with the), and forms a screw thread (17a) in the interior of the induction hole 17, by fastening the closing bolt 18 to the induction hole 17 is formed to fill the induction hole (17). In addition, the threaded portion (19a) is formed on one side to be fastened to the screw thread (17a) of the induction hole (17) and is provided with a separate air injection pipe 19 of the cross-section is coupled to the hose 20 for discharging the compressed air to the other side do.

이와 같이 형성한 몰드를 이용한 수지제품 성형방법을 살펴보면 다음과 같다. 우선 상판(11)과 하판(12)의 홈(13,14)에 반고체 상태의 수지제품(160)을 삽입하고, 상기 상판(11)과 하판(12)을 클램프(15)로 고정하여 서로 밀착 고정한 다음 반고체 상태의 수지제품(16)이 고체상태로 경화되는 일정 시간이 경과한 후에 홈(13,14)과 연통되게 형성된 유도공(17)을 메우며 체결된 마감용 볼트(18)를 탈거하고, 상기 유도공(17)의 나사산(17a)에 에어주입관(19)의 나사부(19a)를 체결하며, 상기 에어주입관(19)에 호스(20)를 결합한 후 에어주입관(19)을 통해 공기를 홈에 주입하여 홈(13,14)과 수지제품(16)의 접착된 부분을 분리한다. 그리고, 상판(11)과 하판(12)을 조인 클램프(15)를 해체한 후 상판(11)과 하판(12)을 분리한 다음 홈(13,14)에서 수지제품(16)을 탈거한다.Looking at the molding method of the resin product using the mold thus formed as follows. First, the semi-solid resin product 160 is inserted into the grooves 13 and 14 of the upper plate 11 and the lower plate 12, and the upper plate 11 and the lower plate 12 are fixed by the clamp 15 to closely adhere to each other. After fixing the semi-solid resin product 16 in a solid state after a certain time has elapsed, the inlet hole 17 formed in communication with the grooves 13 and 14 is filled, and the fastening finishing bolt 18 is removed. The screw portion 19a of the air injection pipe 19 is fastened to the screw thread 17a of the induction hole 17, and the air is introduced through the air injection pipe 19 after the hose 20 is coupled to the air injection pipe 19. Is injected into the groove to separate the bonded portion of the groove (13, 14) and the resin product (16). Then, after disassembling the clamp 15 that joins the upper plate 11 and the lower plate 12, the upper plate 11 and the lower plate 12 are separated, and then the resin product 16 is removed from the grooves 13 and 14.

이상에서 설명한 본 고안에 따르면, 제품형상의 홈이 형성된 상판과 하판에 홈과 연통되는 유도공을 형성하고 상기 유도공에 체결되는 공기주입관과 마감용 볼트를 구비한 수지제품 성형용 몰드를 형성하여 상기 공기주입관과 유도공을 통해 압축공기를 주입해 일차적으로 몰드의 홈에서 경화된 수지제품을 분리함으로써 몰드에서의 수지제품 탈거시 발생하는 변형 및 파손을 방지하게 되는 효과가 있다.According to the present invention described above, by forming an induction hole in communication with the groove in the upper plate and the lower plate is formed in the product shape groove and forming a mold for molding a resin product having an air injection pipe and a closing bolt fastened to the induction hole Compressed air is injected through the air injection pipe and the induction hole, thereby primarily separating the cured resin product from the groove of the mold, thereby preventing deformation and damage occurring when the resin product is removed from the mold.
