Zusammenfassung: | Disclosed is an automatic combination device for upper and lower molds of an injection molding machine. The disclosed content consists of an upper mold and a lower mold that are butt-combined and includes an upper mold coupler formed on the lower surface of the upper mold and a lower mold coupler formed on the upper surface of the lower mold. The lower mold coupler is formed with a protrusion part having an opening part at the upper end thereof and is fitted to a lower opening part of the upper mold coupler. The lower mold coupler is inserted into an inner insertion part of the lower opening of the upper mold coupler by the length of the protrusion part so that the flow space can be expanded. Accordingly, when the upper mold and the lower mold are combined, and molding resin is filled in a molding groove, the gas remaining is rapidly discharged, thereby significantly reducing the defect rate of a molded product.
사출성형기의 상,하형 자동 결합장치가 개시된다. 개시된 내용은 맞대어져 결합되는 상부금형과 하부금형으로 이루어지고, 상부금형의 저면에 형성되는 상부금형커플러와, 하부금형의 상면에 형성되는 하부금형커플러를 포함하고, 하부금형커플러는 상단에 개구부를 갖는 돌출부가 형성되고, 상부금형커플러의 하단 개구부에 끼움결합되는 것이며, 하부금형커플러는 돌출부의 길이만큼 상부금형커플러의 하단 개구부의 내측 삽입부에 끼워져 삽입되어 유량공간이 확대될 수 있도록 한다. 이에 따르면, 상부금형과 하부금형이 결합되고 성형홈의 내부에 성형 수지가 충진될때 잔류하는 가스를 신속히 배출시킴으로써 성형품의 불량발생률을 현저히 낮출 수 있는 효과가 있다. |
