The utility model relates to a rotary core-extracting mechanism of a one-outlet multi-injection mould, which comprises a mould frame; the mould frame is provided with a moving mould; the moving mould is provided with a plurality of mould cavities; each mould cavity is provided with a threaded core; the lower part of the threaded core is provided with a core-extracting gear; the mechanism is characterized in that a plurality of core-extracting gears are driven by a rack; the rack is arranged on an oil cylinder support; the oil cylinder support is arranged on the mould frame; the oil cylinder support is also provided with an oil cylinder; and the rack is driven by the oil cylinder. The technical scheme is characterized in that all threaded cores are driven by the same oil cylinder through a transmission mechanism, not only has simple structure and low manufacturing cost, but also can ensure that all the threaded cores synchronously rotate when in core extraction, thereby ensuring that internal thread lines of the plastic pieces are not damaged, and percent of pass of the plastic pieces is improved.

Description

One goes out the rotation core-pulling mechanism of many injection molds
Technical field
The utility model relates to a kind of one rotation core-pulling mechanism that goes out many injection molds, belongs to the plastics machinery technical field.
Background technology
The working of plastics that has internal thread for manufacturing; the common mode of loosing core is to adopt the rotation of screw thread fuse to loose core at present; promptly when loosing core, drive the screw thread fuse by oil motor and rotate along the internal thread of working of plastics, such mode of loosing core can effectively play the effect of protection internal thread.But go out the mould of many (promptly a secondary mould is produced a plurality of working of plastics) for one, because of a plurality of screw thread fuses are arranged on the mould, each screw thread fuse is driven by an oil motor, therefore need to be equipped with a plurality of oil motors, this mould is complex structure not only, the manufacturing cost height, and each screw thread fuse works alone by the oil motor drive, therefore when loosing core, be difficult to guarantee that all screw thread fuses rotate synchronously, destroy the internal thread of working of plastics easily, reduced the qualification rate of working of plastics.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, production cost is low, the rotation synchronously of all screw thread fuses is deviate from when loosing core, the internal thread of guaranteeing working of plastics is not damaged, thereby improves a rotation core-pulling mechanism that many injection molds of the qualification rate of working of plastics.
The technical scheme that the utility model adopted is to achieve the above object of the invention:
One goes out the rotation core-pulling mechanism of many injection molds, comprise mould bases, dynamic model is installed on the mould bases, a plurality of die cavitys are arranged on the dynamic model, each die cavity is furnished with a screw thread fuse, the gear of loosing core is installed in screw thread fuse bottom, it is characterized in that above-mentioned a plurality of gear of loosing core by rack drives, described tooth bar is installed on the cylinder bracket, and cylinder bracket is installed on the mould bases, described cylinder bracket is also installed oil cylinder, and described tooth bar is driven by oil cylinder.
The characteristics of the technical program are that whole screw thread fuses are driven by transmission mechanism by same oil cylinder, not only simple in structure, low cost of manufacture, and can guarantee that whole screw thread fuses rotate synchronously when loosing core, thereby the internal thread of guaranteeing working of plastics be not damaged, improved the qualification rate of working of plastics.
Described die cavity has 24, wherein per 6 die cavitys are one group, the gear of loosing core of 6 screw thread fuses of every group of die cavity correspondence is by gear set drive, per two gear trains are driven by a toothed rack, described gear train comprises driving gear, the driving gear center have one with the tooth post of tooth bar engagement, described driving gear drives first gear of loosing core, first gear driven first driven gear of loosing core, first driven gear drives second gear of loosing core, second gear driven second driven gear of loosing core, and second driven gear drives the 3rd, the 4th, the 5th gear of loosing core, the 3rd gear driven the 3rd driven gear of loosing core, the 3rd driven gear drive the 6th gear of loosing core.The technical program is one to go out the transmission mechanism of 24 mould correspondence.
Description of drawings
Fig. 1 is to use the structural representation of the corresponding mould of the utility model embodiment;
Fig. 2 is the partial enlarged drawing in U zone among Fig. 1;
Fig. 3 is the structural representation of core-pulling mechanism among Fig. 1;
Fig. 4 is the transmission mechanism structural representation of core-pulling mechanism among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Shown in Fig. 1-4, one goes out the rotation core-pulling mechanism of many injection molds, comprise mould bases 1, dynamic model 2 is installed on the mould bases 1, a plurality of die cavitys 21 are arranged on the dynamic model 2, each die cavity 21 is furnished with a screw thread fuse 6, there is the external screw thread 61 with the screw-internal thread fit of working of plastics 7 screw thread fuse 6 upper ends, the gear of loosing core is installed in screw thread fuse 6 bottoms, the gear of loosing core is driven by tooth bar 5, and described tooth bar 5 is installed on the cylinder bracket 3, and cylinder bracket 3 is installed on the mould bases 1, described cylinder bracket 3 is also installed oil cylinder 4, and described tooth bar 5 is driven by oil cylinder 4.Described die cavity 21 has 24, wherein per 6 die cavitys 21 are one group, the gear of loosing core of 6 screw thread fuses 6 of every group of die cavity 21 correspondences is by gear set drive, per two gear trains are driven by a toothed rack 5, described gear train comprises driving gear 11, driving gear 11 centers have one with the tooth post of tooth bar 5 engagement, described driving gear 11 drives first gear 12 of loosing core, first the loose core gear 12 drives first driven gear 13, first driven gear 13 drives second gear 14 of loosing core, second the loose core gear 14 drives second driven gear 15, second driven gear 15 drives the 3rd, the 4th, the 5th gear 16 of loosing core, 17,18, the 3rd loose core gear 16 drives the 3rd driven gear 19, the three driven gears 19 and drives the 6th gear 20 of loosing core.The characteristics of the technical program are that 24 screw thread fuses 6 are driven by transmission mechanism by same oil cylinder 4, not only simple in structure, low cost of manufacture, and can guarantee that whole screw thread fuses 6 rotate synchronously when loosing core, thereby the internal thread of guaranteeing working of plastics 7 is not damaged, and has improved the qualification rate of working of plastics 7.
