Description
Technical field
The present invention relates to field of die equipment, especially a kind of preceding mould screw thread core pulling mechanism.
Background technique
Core pulling is to belong to " overhead kick processing system " for handle the position that can not be demoulded on product die joint, is mold
A kind of structure.Core pulling definition: guarantee the mechanism that product smoothly demoulds, also referred to as sliding block.For example there is hole in plastic parts side, is being opened
Afterwards, if the fuse in this hole is not taken out, product can not be ejected.
Mould structure will use the structure of sliding block at this time, the fuse in hole is made into movable, be matched with inclined guide pillar and cover half
It closes, makes sliding block mobile with die sinking or molding.Core pulling is just named in this movement.
At present it is known that screw thread core pulling mechanism be to be realized by installing one group of gear assembly in rear mold, mold design
When need towards rear mold to form the mechanism of screw thread core pulling.But this mechanism just necessarily has limitation, needs to require
Product can only unidirectional core pulling, if there is core pulling at upper and lower both ends, design is just unable to complete.
Summary of the invention
The purpose of the present invention is to solve defects of the existing technology, provide a kind of preceding mould screw thread core pulling mechanism.
To achieve the goals above, The technical solution adopted by the invention is as follows:
A kind of preceding mould screw thread core pulling mechanism, including being located at the gear ring on the outside of fuse, gear wheel is engaged in the outside of gear ring, gear wheel
Middle part connects power-driven mechanism, and the end of the fuse is equipped with fixed gear, and fixed gear is set in the end of fuse, Gu
The outside of fixed gear is equipped with card tooth mold insert, and card tooth mold insert positions fixed gear, and the inner hole of fixed gear is equipped with interior tooth, fuse
Outside is equipped with the spiral teeth cooperated with interior tooth.
Further, the power-driven mechanism includes the intermediate gear connecting with gear wheel middle part, is engaged with intermediate gear
Straight trip rack gear and with the oil cylinder that connect of straight trip rack gear.
Further, the intermediate gear is connected with the center of gear wheel by connecting shaft, and the both ends of connecting shaft connect bearing,
Bearing is mounted on die apparatus.
Further, the intermediate gear and gear wheel are coaxial.
Further, the spiral teeth extend along the length direction of fuse.
The invention has the benefit that core-pulling mechanism is combined using one group of screw thread, when mold is opened, played using oil cylinder
One pulling force effect, and screw thread combination is cooperated by the thread between fixed gear and fuse, and fuse is driven up to move,
It is final to realize preceding mould screw thread core pulling, significant reference can be provided for the design of preceding mould screw thread core pulling, avoid some products
It is not available upside-down mounting mould and is unable to complete the awkward condition of mold design.
Detailed description of the invention
Fig. 1 is the structural schematic diagram at present invention top visual angle；
Fig. 2 is front schematic view of the invention；
Fig. 3 is the structural schematic diagram of bottom views of the present invention.
Specific embodiment
As shown in Figure 1 to Figure 3, a kind of preceding mould screw thread core pulling mechanism, the gear ring 2 including being located at 1 outside of fuse, gear ring 2
Gear wheel 3 is engaged in outside, and the middle part of gear wheel 3 connects power-driven mechanism, and the end of fuse 1 is equipped with fixed gear 4, fixed tooth
Wheel 4 is set in the end of fuse 1, and the outside of fixed gear 4 is equipped with card tooth mold insert 5, and card tooth mold insert 5 positions fixed gear 4, Gu
The inner hole of fixed gear 4 is equipped with interior tooth, and the outside of fuse 1 is equipped with the spiral teeth cooperated with interior tooth.
Further, power-driven mechanism include with the intermediate gear 6 connected in the middle part of gear wheel 3, engaged with intermediate gear 6
Straight trip rack gear 7 and the oil cylinder 8 being connect with straight trip rack gear 7.
Further, intermediate gear 6 is connected with the center of gear wheel 3 by connecting shaft 9, and the both ends of connecting shaft 9 connect bearing
10, bearing 10 is mounted on die apparatus.
In the present invention, intermediate gear 6 and gear wheel 3 are coaxial, and spiral teeth extend along the length direction of fuse 1.
The application method of the structure is as follows: before mold is opened, 8 pumpback of oil cylinder drives straight trip rack gear 7 to take out toward arrow direction
Dynamic, by the cooperation of teeth, rack gear 7 of keeping straight on drives gear wheel 3 to rotate along the direction of the arrow, and gear wheel 3 drives 1 direction of fuse to turn
It is dynamic.The end of fuse 1 is equipped with fixed gear 4, and fixed gear 4 is set in the end of fuse 1, and the outside of fixed gear 4 is equipped with card
Tooth mold insert 5, card tooth mold insert 5 position fixed gear 4, and the inner hole of fixed gear 4 is equipped with interior tooth, the outside of fuse 1 be equipped with it is interior
The spiral teeth of tooth cooperation, when fuse 1 rotates, due to the spiral teeth and the interior tooth phase interworking of fixed gear 4 outside fuse 1
It closes, in the case that fixed gear 4 is fixed, fuse 1 can up walk about with rotation, and at the same time, fuse 1 is inside product 11
Screw thread follows the movement of fuse and core pulling detaches product, and so far, the screw thread core pulling of preceding mold core is fully completed.
The core-pulling mechanism is combined using one group of screw thread, when mold is opened, plays a pulling force effect using oil cylinder, and spiral shell
Line combination is cooperated by fixed gear with the thread between fuse, and fuse is driven up to move, final to realize preceding mould screw thread
Core pulling can provide significant reference for the design of preceding mould screw thread core pulling, avoid some products be not available upside-down mounting mould and
It is unable to complete the awkward condition of mold design.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention
Principle, various changes and improvements may be made to the invention without departing from the spirit and scope of the present invention, these variation and
Improvement is both fallen in the range of claimed invention.The present invention claims protection scope by appended claims and its
Equivalent defines.
