본 고안은 사출금형의 문자코어 착탈구조에 관한 것으로서, 특히 고정측 형판에 삽착공과 삽입공이 형성된 고정캐비티를 설치하고, 외부에는 장홈이 요설된 고정측받침판을 설치하여, 고정홈이 요설된 문자코어를 삽착공에 삽착하되, 삽입공으로는 고정키이를 삽입시켜 키이의 일단이 문자코어의 고정홈에 끼워 고정하고, 취출 또는 가능하게 하므로써 문자코어의 착탈을 용이하게 할 수 있도록 한 사출금형의 문자코어 착탈 구조에 관한 것이다.The present invention relates to a character core detachable structure of an injection mold, and in particular, a fixing cavity in which an insertion hole and an insertion hole is formed is installed in a fixed side template, and a fixed side support plate in which a long groove is recessed is installed on the outside, and a fixed groove is required. Inserting the core into the insertion hole, but inserting the fixing key into the insertion hole, the end of the key is inserted into the fixing groove of the character core to be fixed, and ejected or enabled, so that the character core can be easily attached and detached. It relates to a core detachable structure.
일반적으로 사출금형에서 제품의 표면에 문자를 인각하는데 있어 별도의 문자코어를 설치하여 사용되어 왔는데 도시된 도면 제5도에서와 같이 고정캐비티(22)상부 일측으로 걸림부가 형성된 삽착공(23)에 걸림구(25)가 형성된 문자코어(24)를 삽착시켜, 고정측받침판(21)에 설치결합하고, 그 외부에는 고정측형판(26)을 설치하였다.In general, in the injection mold has been used to install a separate character core in the engraving of the character on the surface of the product, as shown in Figure 5 shown in Figure 5 in the insertion hole 23 is formed with a locking portion on the upper side of the fixing cavity 22 The character core 24 in which the catching opening 25 was formed was inserted, it was attached to the fixed side support plate 21, and the fixed side plate 26 was provided in the outside.
또한, 상기와 같은 구조에서 가동측형판(27)과 고정측받침판(21)사이에 설치된 고정캐비티(22)내로 용융수지를 주입하여 제품(28)을 성형하는 과정에 있어서, 고정캐비티(22)에 설치된 문자코어(24)가 제품(28)의 표면에 문자를 인각하는 것인바, 문자코어(24)가 고정캐비티(22)에 걸림구(25)에 의해 삽착고정되고, 그 외부에는 고정측받침판(21)과 고정측형판(26)이 설치되어 사용하였으며, 문자코어(24)를 착탈하고자 할때엔 사출금형의 고정측받침판(21)과 가동측형판(27)을 분리시키고 고정측형판(21)을 격리시킨 다음, 고정측형판(26)과 고정캐비티(22)를 차례로 분해하여 문자코어(24)를 착탈하므로써, 성형제품의 문자인각 변경에 따라 문자코어의 교체작업이 용이하지 못하여 작업시간이 길고, 사출금형에 가해지는 예열 및 승온과정에서 전기적 소모가 많음에 따라 제조원가가 상승됨은 물론 사출금형으로 사출성형 제품을 제 성형사출할 때 금형의 온도차이가 심하여 제품에 수축(Sink Mark) 및 손상을 주어 불량이 발생하는 등의 문제점이 있었다.In addition, in the above structure, in the process of forming the product 28 by injecting molten resin into the fixed cavity 22 installed between the movable side plate 27 and the fixed side support plate 21, the fixed cavity 22 The character core 24 installed in the indentation of the character on the surface of the product 28, the character core 24 is fixed to the fixing cavity 22 by the locking hole 25, the outside fixed side The supporting plate 21 and the fixed side plate 26 are installed and used. When the character core 24 is attached or detached, the fixed side support plate 21 and the movable side plate 27 of the injection mold are separated and the fixed side plate (21) is separated, and then the fixed side plate 26 and the fixed cavity 22 are disassembled in order to remove the character core 24, so that the replacement of the character core is not easy in accordance with the change in the character of the molded product. Due to the long working time and high electrical consumption during preheating and heating D. There was a problem in that the manufacturing cost was increased as well as the temperature difference between the molds when the injection molding products were injection molded into injection molds caused severe shrinkage and damage to the products.
따라서, 본 고안은 상기와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로서, 고정캐비티에 삽착공을 관통되게 형성하고, 삽착공 일측에 삽칩공을 형성하여 된 고정캐비터를 고정측받침판에 설치하고, 그 외부에는 장홈이 형성된 고정측형판을 설치하여 일측에 고정홈이 요설된 문자코어를 삽착공에 삽착시키되, 고정키이를 삽입공에 삽입시키고 문자코어의 고정홈에 끼워 고정되도록 하므로써, 사출금형의 가동 측형판을 분리시킨 상태에서 문자코어를 용이하게 탈착시킬 수 있도록 한 것을 목적으로 한다.Therefore, the present invention has been devised to solve the conventional problems as described above, and to form the insertion hole through the fixing cavity, and to form a insertion chip hole on one side of the insertion hole is installed on the fixed side support plate By inserting a fixed side plate with a long groove formed on the outside thereof, the character core with the fixed groove on one side is inserted into the insertion hole, by inserting the fixing key into the insertion hole and being fixed to the fixing groove of the character core. It is an object of the present invention to enable the character core to be easily detached in a state where the movable side plate is removed.
이하 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings.
가동 측형판(12)과 고정측받침판(2)으로 구성되는 사출금형 (1)에 있어서, 고정측받침판(2)에 설치되어 있는 고정캐비티(3)에 설치된 문자코어(8)를 상기 고정캐비티(3)의 일측에 삽착공(4)을 관통되게 형성하고, 삽착공(4) 일측소정 위치에는 삽입공(5)이 연결관통되게 형성하여 고정측받침판(2) 중앙부에 설치하되, 그 내부 일측에 장홈(7)이 요설된 고정측형판(6)을 고정캐비티(3) 외부에 설치하여 삽입공(5)이 장홈(7)과 개방되게 하고, 일측에 고정홈(9)과 일단에 문자(10)가 각인된 문자키이(8)를 고정홈(9)이 삽입공(5)과 일치되게 삽착하고 고정키이(11)를 고정측형판(6)의 장홈(7)을 통해 삽입공(5)에 삽입시켜 일단이 문자코어(8)의 고정홈(9)에 끼워져 고정시킬 수 있도록 한 것이다.In the injection mold (1) consisting of the movable side plate (12) and the fixed side support plate (2), the character core (8) provided in the fixed cavity (3) provided on the fixed side support plate (2) is fixed to the fixed cavity. The insertion hole (4) is formed in one side of the through hole (3), and the insertion hole (5) is formed in the predetermined position on the one side of the insertion hole (4) so that the connection hole is formed and installed in the center of the fixed side support plate (2). A fixed side plate 6 having a long groove 7 on one side is installed outside the fixing cavity 3 so that the insertion hole 5 can be opened with the long groove 7, and on one side of the fixed groove 9. Insert the character key (8) in which the character (10) is imprinted so that the fixing groove (9) coincides with the insertion hole (5) and insert the fixing key (11) through the long groove (7) of the fixed side plate (6). (5) so that one end is inserted into the fixing groove (9) of the character core (8) to be fixed.
이와같이 구성된 본 고안은 사출금형(1)에서 가동측형판(12)을 분리한 상태로 고정측받침판(2)에 설치된 고정캐비티(3)에 형성시키고 삽착공(4)과 삽입공(5)이 일단에 문자(10)가 인각된 문자코어(8)의 일측에 고정홈(9)이 요설되게 하며, 이를 가동측형판(12)측으로 향하도록 하고, 고정홈(9)은 삽입공(5)과 일치되게 하여 고정키이(11)의 일단이 고정측형판(6)에 형성된 장홈(7)을 통하여 삽입공(5)으로 삽입시켜 고정하므로써 고정홈(9)에 끼워지게하여 문자키이(8)를 착설한 것이다.The present invention configured as described above is formed in the fixing cavity (3) installed on the fixed side support plate (2) in a state in which the movable side plate (12) is separated from the injection mold (1) and the insertion hole (4) and the insertion hole (5) The fixing groove 9 is recessed at one side of the character core 8 at which the character 10 is engraved at one end thereof, so that the fixing groove 9 faces the movable side plate 12 side, and the fixing groove 9 is an insertion hole 5. And the end of the fixing key 11 is inserted into the insertion hole 5 through the long groove 7 formed in the fixed side plate 6 so as to be fitted into the fixing groove 9 so that the character key 8 is fitted. Will be installed.
이 상태에서 가동측형판(12)을 고정측받침판(2)에 접합되게 하여 용융된 합성수지재를 주입시켜 가동측형판(12)과 고정캐비티(3) 사이의 제품성형부에서 사출성형제품(13)을 제작한다.In this state, the movable side plate 12 is joined to the fixed side support plate 2, and the molten synthetic resin material is injected to inject the molded product from the product forming part between the movable side plate 12 and the fixed cavity 3. ).
이 고정에서 문자코어(8)의 일단에 인각된 문자(10)가 동시에 성형될 수 있도록 하였다.In this fixing, the letters 10 engraved on one end of the letter core 8 can be molded simultaneously.
또한 이와같이 제품을 성형하는 중에 다른 제품을 성형하거나 문자코어(8)를 교환하고자 할때에는 사출금형(1)의 가동측형판(12)을 분리시킨 상태에서 문자키이(8)의 고정홈(9)에서 고정키이(11)의 일단을 취출하고 별도의 치구를 사용하여 문자코어(8)를 취출하면 되는 것이다.In addition, when forming a product in this way, when forming another product or to replace the character core 8, the fixing groove 9 of the character key 8 with the movable side plate 12 of the injection mold 1 removed. Take out one end of the fixed key (11) and using a separate jig to take out the character core (8).
상술한 바와 같이 본 고안은, 사출금형이 사출성형기에 장착된 상태에서 문자코어가 탈착이 가능하여 작업성 및 시간단축이 용이하고, 사출금형을 예열 및 승온시키는 과정도 단축되어 생산성 향상을 높여주는 동시에 원가절감을 기할 수 있는 특징으로 한다.As described above, the present invention allows the character core to be detachable in the state in which the injection mold is mounted in the injection molding machine, so that the workability and time can be shortened, and the process of preheating and raising the injection mold is also shortened to improve productivity. At the same time, it is characterized by cost reduction.
