By adopting the technical scheme, the product inside the die is conveniently injected for the second time by arranging the two-shot injection hole.
The invention is further provided with: the bottom of the spring plate is provided with a lower die holder.
By adopting the technical scheme, the double-shot injection mold can be conveniently installed on the workbench by arranging the lower die holder, and the double-shot injection mold is fixed.
In summary, the invention has the following beneficial effects:
through designing a die cavity with traditional double-colored injection mold, then after the mould die sinking, drive an injection molding mold insert and two injection molding mold inserts respectively through going position loose core hydro-cylinder and remove to carry out the compound die, make it carry out twice injection molding's setting to the injection molding, reached can make double-colored mould single-cavity injection molding's function, thereby effectively improve work efficiency, double-colored injection mold also only needs a set of mould and an ejecting system simultaneously, has also reduced the manufacturing cost of mould.
