Specific embodiment
The embodiments of the present invention are described in further detail below in conjunction with Detailed description of the invention, but the present embodiment and are not had to
In limitation the utility model, all similar structures and its similar variation using the utility model should all be included in the utility model
Protection scope, the pause mark in the utility model indicates the relationship of sum.
As Figure 1-Figure 2, a kind of bicolor injection mould provided by the utility model embodiment, it is characterised in that: packet
Die holder (not shown), turntable 3 are included, and the two cover half cores 11,12 being fixed on die holder, one of cover half core is first
Cover half core 11, another cover half core are the second cover half core 12, are formed with a cover half chamber on each cover half core, and each
The fixed die ejector 10 for being ejected forward the intracavitary injecting products of cover half is designed on cover half core；
It is symmetrically fixed there are two the identical moving-mould-core 2 of structure on the turntable 3, it is formed with dynamic model chamber on moving-mould-core 2, is moved
It is equipped with the mold insert 9 that can be slid back and forth in die cavity, the cover half chamber of the dynamic model chambers of two moving-mould-cores 2 and two cover half cores 11,12 is one by one
Face；
The moving-mould-core 2 is equipped with the dynamic model top pillar 6 that can be slid back and forth, and is fixed with the first ejector retainner plate 71 on dynamic model top pillar 6,
The first thimble 81 is fixed on first ejector retainner plate 71, dynamic model chamber offers the centre hole entered and left for the first thimble；
The moving-mould-core 2 is equipped with the second ejector retainner plate 72 that can be slid back and forth, and fixes the second thimble on the second ejector retainner plate 72
82, the second thimble 82 and mold insert 9 are affixed；
The moving-mould-core 2 is equipped with the backing plate 5 that can be horizontally slipped, and the sideslip oil cylinder for driving backing plate 5 to horizontally slip
4, the backing plate 5 is staggered with the second ejector retainner plate 72 or so, and backing plate 5 can slide into the position Chong Die with the second ejector retainner plate 72 or so
It sets.
The utility model embodiment is mounted on injection molding machine and uses, and is suitble to double-shot moulding product, and working method is as follows:
In use, die holder to be fixed on to the fixed part of injection molding machine folding modular system, the shaft of turntable is mounted on injection molding machine
Open and close the movable part of modular system；
Under original state, backing plate is in the position being staggered with the second ejector retainner plate or so, before the second ejector retainner plate moves forward at this time
Stop, mold insert also move forward to preceding dead-centre position therewith, are aligned before and after the second ejector retainner plate and backing plate；If face the first cover half core is dynamic
Mold core is the first moving-mould-core, and the moving-mould-core of face the second cover half core is the second moving-mould-core；
Start the injection molding of the first color at this time, dynamic model chamber the first color of composition of the cover half chamber of the first cover half core and the first moving-mould-core at
Pattern chamber injects the first color injection molding melt into the first color shaping mold cavity at this time, after the first color injection molding melt is cooled and shaped, note
Molding machine opens and closes modular system and drives turntable and moving-mould-core Forward die sinking, so that the first moving-mould-core and the first cover half core disengage, it is fixed simultaneously
First color is also molded semi-finished product from the intracavitary ejection of cover half by mould thimble, and then turntable rotates 180 degree, and the first moving-mould-core is with first
Color injection molding semi-finished product turn to the position of face the second cover half core, while the second moving-mould-core turns to the position of face the first cover half core
It sets；
Then injection molding machine folding modular system drives turntable and moving-mould-core to move back molding, so that the first moving-mould-core and the second cover half
Core pairing (while the second moving-mould-core also with the first cover half core pairing), then dynamic model top pillar drives the first ejector retainner plate to move back, thus
It drives the first thimble to move back to rear stop, is ejected so that the first color is molded in the driven die cavity of semi-finished product, then the second ejector retainner plate
It drives the second thimble to move back, so that mold insert be driven to move back to rear stop, is staggered before and after rear second ejector retainner plate and backing plate at this time, at this time
Sideslip oil cylinder driving backing plate slides into the position Chong Die with the second ejector retainner plate or so, and then the second ejector retainner plate passes through the second thimble band
Dynamic mold insert Forward is realized the adjusting of the second colour pattern chamber by mold insert, is at this time until the front face of the second ejector retainner plate resists backing plate
It can start the injection molding of the second color, the cover half chamber of the second cover half core becomes the second color shaping mold cavity, at this time into the second color shaping mold cavity
The second color injection molding melt is injected, after the second color injection molding melt is cooled and shaped, injection molding machine opens and closes modular system and drives turntable and dynamic model
Core Forward die sinking, so that the first moving-mould-core and the disengagement of the second cover half core, while fixed die ejector is also by double-shot moulding finished product from cover half
Intracavitary ejection, then turntable rotates 180 degree, and the first moving-mould-core is back to the position of face the first cover half core again, double-shot moulding at
The injection molding of product is accused and is finished；
After removing double-shot moulding finished product, the second ejector retainner plate is moved back to rear stop, and then sideslip oil cylinder driving backing plate slides into
The position being staggered with the second ejector retainner plate or so, then the second ejector retainner plate drives mold insert to move forward to preceding stop by the second thimble, so
Injection molding machine folding modular system drives turntable and moving-mould-core to move back molding afterwards, so that the first moving-mould-core and the first cover half core pairing are (same
When the second moving-mould-core also with the second cover half core pairing), double-shot moulding operation next time can be started.
