Muzzle；
Detent mechanism, the detent mechanism is made up of two positioning guide columns, where plane where two positioning guide column and sprue bush
Plane is vertical, and each positioning guide column is made up of the first locating piece for matching and the second locating piece, and first locating piece is set
In on caster, second locating piece is arranged in male template；
Mould emptier, the mould emptier is arranged at mold bottom, including thimble and ceiling device；
When the die is closed, from two coloring agents of sprue bush injection different colours, the injection of first time is completed, then by controlling to turn to
Mechanism, 180 degree rotates caster, is turned in place when the first locating piece and the second locating piece overlap to be set to after rotation, carries out second
Secondary injection, molds after completing double-shot moulding, the product after ceiling device controls thimble to eject quadric injection mould.
Further, the steering mechanism includes being arranged at the axle bed at male template bottom centre, is arranged at axle bed center
And run through male template and extend downwardly in caster is resisted against in the rotating shaft outside mould, the rotating shaft, also including being provided with for protecting
The axle sleeve of rotating shaft is protected, the axle sleeve is arranged between axle bed and mould.
Further, the ceiling device includes top board, top plate guide post and top plate guide bushing, and the top board is arranged at thimble bottom
Portion, is additionally provided with the push back pin for reducing thimble on the top board, top plate guide bushing is arranged outside the top plate guide post.
Beneficial effect：The present invention only needs to folding mould once just into double-shot moulding is completed, and substantially increases the efficiency of production,
The double-color mold supports that many set products are carried out simultaneously, and the further improve production efficiency of energy, the mould passes through localization machine when rotating
Structure can accurately position steering angle, be greatly reduced the product error rate after double-shot moulding, improve qualification rate.
