本实用新型实施例安装在注塑机上使用,适合双色注塑产品,其工作方式如下:The utility model embodiment is installed on the injection molding machine and is suitable for two-color injection molding products. Its working method is as follows:

使用时,将模座固定在注塑机开合模系统的固定部,将转盘的转轴安装在注塑机开合模系统的活动部;When in use, fix the mold base on the fixed part of the mold opening and closing system of the injection molding machine, and install the rotating shaft of the turntable on the movable part of the mold opening and closing system of the injection molding machine;

初始状态下,垫板处在与第二顶针板左右错开的位置,此时第二顶针板前移至前止点,镶件也随之前移至前止点位置,第二顶针板与垫板前后对齐;设正对第一定模芯的动模芯为第一动模芯,正对第二定模芯的动模芯为第二动模芯;In the initial state, the backing plate is in a position staggered left and right with the second ejector plate. At this time, the second ejector plate moves forward to the front dead center, and the insert also moves forward to the front dead center position. The second ejector plate and the backing plate Front and rear alignment; Let the moving mold core facing the first fixed mold core be the first moving mold core, and the moving mold core facing the second fixed mold core be the second moving mold core;

此时开始第一色注塑,第一定模芯的定模腔与第一动模芯的动模腔组成第一色成型模腔,此时向第一色成型模腔内射入第一色注塑熔液,待第一色注塑熔液冷却成型后,注塑机开合模系统带动转盘及动模芯前移开模,使得第一动模芯与第一定模芯脱开,同时定模顶针也将第一色注塑半成品从定模腔内顶出,然后转盘转动180度,第一动模芯带着第一色注塑半成品转动至正对第二定模芯的位置,同时第二动模芯转动至正对第一定模芯的位置;At this time, the first color injection molding starts. The fixed mold cavity of the first fixed mold core and the movable mold cavity of the first movable mold core form the first color molding cavity. At this time, the first color molding cavity is injected into the first color molding cavity. After the first color injection melt is cooled and formed, the mold opening and closing system of the injection molding machine drives the turntable and the movable mold core to move the mold forward, so that the first movable mold core is separated from the first fixed mold core, and the mold is fixed at the same time The thimble also ejects the semi-finished product of the first color injection from the cavity of the fixed mold, and then the turntable rotates 180 degrees. The mold core rotates to the position facing the first fixed mold core;

然后注塑机开合模系统带动转盘及动模芯后移合模,使得第一动模芯与第二定模芯对合(同时第二动模芯也与第一定模芯对合),然后动模顶柱带动第一顶针板后移,从而带动第一顶针后移至后止点,从而将第一色注塑半成品从动模腔中顶出,然后第二顶针板带动第二顶针后移,从而带动镶件后移至后止点,此时后第二顶针板与垫板前后错开,此时侧滑油缸驱动垫板滑动至与第二顶针板左右重叠的位置,然后第二顶针板通过第二顶针带动镶件前移,直至第二顶针板的前板面抵住垫板,通过镶件实现第二色型腔的调节,此时即可开始第二色注塑,第二定模芯的定模腔成为第二色成型模腔,此时向第二色成型模腔内射入第二色注塑熔液,待第二色注塑熔液冷却成型后,注塑机开合模系统带动转盘及动模芯前移开模,使得第一动模芯与第二定模芯脱开,同时定模顶针也将双色注塑成品从定模腔内顶出,然后转盘转动180度,第一动模芯重新回至正对第一定模芯的位置,双色注塑成品的注塑即告完毕;Then the mold opening and closing system of the injection molding machine drives the turntable and the movable mold core to move backward to close the mold, so that the first movable mold core and the second fixed mold core are aligned (at the same time, the second movable mold core is also aligned with the first fixed mold core), Then the ejector column of the movable mold drives the first ejector plate to move backward, thereby driving the first ejector pin to move back to the rear dead point, thereby ejecting the semi-finished product of the first color injection molding from the movable mold cavity, and then the second ejector plate drives the second ejector pin to the rear At this time, the second thimble plate and the backing plate are staggered back and forth. At this time, the side slip cylinder drives the backing plate to slide to the position overlapping with the second thimble plate left and right, and then the second thimble plate The plate drives the insert forward through the second thimble until the front plate of the second thimble plate touches the backing plate, and the second color cavity is adjusted through the insert. At this time, the second color injection can be started, and the second fixed The fixed mold cavity of the mold core becomes the second color molding cavity. At this time, the second color injection molten liquid is injected into the second color molding cavity. After the second color injection molten liquid is cooled and formed, the injection molding machine opens and closes the mold system Drive the turntable and the movable mold core to move the mold forward, so that the first movable mold core is separated from the second fixed mold core. At the same time, the fixed mold thimble also ejects the two-color injection molded product from the fixed mold cavity, and then the turntable rotates 180 degrees. Once the moving mold core returns to the position facing the first fixed mold core, the injection molding of the two-color injection molding product is completed;

取下双色注塑成品后,第二顶针板后移至后止点,然后侧滑油缸驱动垫板滑动至与第二顶针板左右错开的位置,然后第二顶针板通过第二顶针带动镶件前移至前止点,然后注塑机开合模系统带动转盘及动模芯后移合模,使得第一动模芯与第一定模芯对合(同时第二动模芯也与第二定模芯对合),即可开始下一次双色注塑作业。After removing the two-color injection molding product, the second ejector plate moves backward to the rear dead center, and then the side-sliding oil cylinder drives the backing plate to slide to a position staggered left and right with the second ejector plate, and then the second ejector plate drives the insert forward through the second ejector pin. Move to the front dead point, and then the mold opening and closing system of the injection molding machine drives the turntable and the movable mold core to move backward to close the mold, so that the first movable mold core is matched with the first fixed mold core (at the same time, the second movable mold core is also aligned with the second fixed mold core) The mold core is matched), and the next two-color injection molding operation can be started.
