Description
Technical field
The utility model relates to injection mold technology, in particular to a kind of de- inner thread device and de- internal screw thread mould
Tool.
Background technique
Screw thread refers to the convex row spiral yarn shaped, with particular cross section produced on cylinder or circular cone parent surface
Play part, internal screw thread refers to that screw thread is set on finished product inner wall, internal screw thread product be widely applied among various products.It is existing
One internal screw thread product of internal screw thread mold does a kind of Leave out thread system, and an interior tooth mold core is got on the bus a bearing position, gear position, and ten
Divide inconvenience, and die manufacturing cost is higher, is not suitable with modern production requirement.
Utility model content
The technical problems to be solved in the utility model is how to provide one kind to produce multiple and different specification internal screw thread products
De- inner thread device and de- internal screw thread mold.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:
A kind of de- inner thread device, including sprocket wheel, gear wheel, pinion gear, first rotating shaft, the second shaft and link block, institute
It states sprocket wheel and the gear wheel all interference is socketed in the first rotating shaft, the pinion gear interference is socketed on second shaft
On, one end of second shaft is equipped with groove, and a part of the link block is embedded in the groove, the gear wheel with
The pinion drive connection.
Preferably, the cross-sectional shape of the link block is I-shaped.
Preferably, which further includes four bearings, and the both ends of the first rotor are socketed in an axis respectively
In the inner ring held, the bitrochanteric both ends are also socketed in respectively in the inner ring of a bearing.
Preferably, which further includes a motor, the rotor transmission connection of the sprocket wheel and the motor.
Technical solutions of the utility model also propose a kind of de- internal screw thread mold, including caster, above-described de- interior spiral shell
Line device and multiple outer pitch thread mold fuses, the outer pitch thread mold fuse are removably connected on the link block.
Preferably, the screw thread model of each outer pitch thread mold fuse is different.
By adopting the above technical scheme, it by sprocket wheel, gear wheel, pinion gear, first rotating shaft, the second shaft and link block, is formed
A kind of de- inner thread device.Gear wheel is driven by sprocket wheel, the large gear turn the small gear, the second shaft of pinion gear socket
Groove can be packed into link block, and link block upper semisection can connect outer tooth mold fuse (what is taken off is internal screw thread product).Manufacture
When the product of different model, it is only necessary to which the outer pitch thread mold fuse on more preferable link block can produce the interior spiral shell of different model
Line finished product.The technical program is simple and effective, can avoid cost caused by the multiple molds of configuration and wastes.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the utility model takes off one embodiment of internal screw thread mold；
Fig. 2 is the structural schematic diagram for the link block that the utility model takes off one embodiment of internal screw thread mold.
In figure, 1- sprocket wheel, 2- gear wheel, 3- pinion gear, 4- first rotating shaft, the second shaft of 5-, 6- link block, 7- bearing,
9- groove, the outer pitch thread mold fuse of 10-.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
Referring to FIG. 1 and FIG. 2, technical solutions of the utility model propose a kind of de- inner thread device, including sprocket wheel 1, canine tooth
Wheel 2, pinion gear 3, first rotating shaft 4, the second shaft 5 and link block 6, sprocket wheel 1 and all interference of gear wheel 2 are socketed on first rotating shaft 4
On, 3 interference of pinion gear is socketed in the second shaft 5, and one end of the second shaft 5 is equipped with groove 9, and a part of link block 6 is embedded
In in groove 9, gear wheel 2 and pinion gear 3 are sequentially connected.
Specifically, the cross-sectional shape of link block 6 is I-shaped, and top view and bottom view are rectangle.It is in side
Open reeded cuboid in portion.In use, the other end of link block 6 is embedded in the groove of external screw thread mold fuse, by transversal
Face is that I-shaped link block 6 drives the rotation of external screw thread mold fuse, realizes de- internal screw thread.
Specifically, which further includes four bearings 7, and the both ends of the first rotor are socketed in a bearing 7 respectively
Inner ring on, bitrochanteric both ends are also socketed in respectively in the inner ring of a bearing 7.
Specifically, which further includes a motor, the rotor transmission connection of sprocket wheel 1 and motor.
Technical solutions of the utility model also propose a kind of de- internal screw thread mold, including caster, above de- internal screw thread dress
It sets and multiple outer pitch thread mold fuses 10, outer pitch thread mold fuse 10 is removably connected on link block 6.
Specifically, the screw thread model of each outer pitch thread mold fuse 10 is different.
By adopting the above technical scheme, by sprocket wheel 1, gear wheel 2, pinion gear 3, first rotating shaft 4, the second shaft 5 and link block
