Abstract
The utility model belongs to the field of injection molds, and particularly relates to a screw rod driving mechanism for rotationally de-threading injection molded products. The screw rod driving mechanism comprises a screw rod, a main driving gear, a gear core, a movable mold portion and a fixed mold portion. An injection molding machine drives the movable mold portion and the fixed mold portion to combine and separate, the screw rod is arranged beside the fixed mold portion, and the main driving gear is mounted on the screw rod and connected with the gear core. The screw rod driving mechanism for rotationally de-threading the injection molded products can save mold cost, realize uniformity of the injection molded products and improve appearance of the injection molded products.
Description
Technical field
The utility model belongs to the injection mold field, relates in particular to a kind of lead screw transmission mechanism that screw thread is taken off in the injection-molded item rotation that is used for.
Background technology
Existing taking off automatically in the screw thread injection mold is generally nothing more than having: chain gear transmission, rack-and-pinion transmission, worm and gear transmission or the like.The disadvantage of last various methodologies is all must the driving energy be provided by the external world, as: hydraulic motor, motor; Oil cylinder, cylinders etc. are so bring die cost to improve; The matching range of mould and injection machine dwindles, and mould appearance is not attractive in appearance, also has in addition except the rack-and-pinion transmission; Outside the worm and gear transmission, the original position of goods screw thread can not accurately be located, and causes the fit angle of each goods and blow molded bottle to occur different.
Summary of the invention
The utility model provides a kind of lead screw transmission mechanism that screw thread is taken off in the injection-molded item rotation that is used for of saving the uniformity of die cost, realization goods and improving mould appearance to above deficiency.
The utility model solves the technical scheme that its technical problem adopted:
This lead screw transmission mechanism; Comprise screw mandrel, main drive gear, gear mold core, dynamic model part, cover half part, injection machine drives dynamic model part and cover half part opening and closing movement, the other screw mandrel that is provided with of cover half part; Main drive gear is housed on the screw mandrel, and main drive gear is connected with gear mold core.
Operation principle: injection machine drives the action of mould active and inactive mold part folding, makes the other screw mandrel of cover half part keep the turnover main drive gear, thereby makes main drive gear carry out positive and negative rotation, and goods are taken off in the rotation of driven gear core.Wherein note opening of mould, must remain unchanged apart from drawing via Theoretical Calculation.
The beneficial effect of the utility model is:
1. saving die cost.
2. realize the uniformity of goods.
3. improved mould appearance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure:
L, screw mandrel, 2, main drive gear, 3, gear mold core, 4, the dynamic model part, 5, the cover half part.
The specific embodiment
Shown in accompanying drawing; This lead screw transmission mechanism; Comprise screw mandrel 1, main drive gear 2, gear mold core 3, dynamic model part 4, cover half part 5, injection machine drives dynamic model part 4 and cover half part 5 opening and closing movements, the cover half part 5 other screw mandrels 1 that are provided with; Main drive gear 2 is housed on the screw mandrel 1, and main drive gear 2 is connected with gear mold core 3.
Operation principle: injection machine drives the action of mould active and inactive mold part 5 foldings, makes cover half part 5 other screw mandrels 1 keep turnover main drive gear 2, thereby makes main drive gear 2 carry out positive and negative rotation, and goods are taken off in 3 rotations of driven gear core.Wherein note opening of mould, must remain unchanged apart from drawing via Theoretical Calculation.
Claims (1)
1. one kind is used for the lead screw transmission mechanism that screw thread is taken off in the injection-molded item rotation; Comprise screw mandrel, main drive gear, gear mold core, dynamic model part, cover half part; It is characterized in that: injection machine drives dynamic model part and cover half part opening and closing movement; The cover half part is other to be provided with screw mandrel, and main drive gear is housed on the screw mandrel, and main drive gear is connected with gear mold core.
