Description
Technical field
A kind of mouth of a river resectoscope is the utility model is related to, particularly relating to that one kind applies in injection mold can be automatically to note
The device that the modeling mouth of a river is cut off.
Background technology
It is well known that as shown in Figure 1, mould injection complete but product also without ejection before the top of rear cavity 1 into
All can be there are regrinding-material 2 on the product of type, the mode that tradition removes regrinding-material 2 is all to be acted first by the thimble in rear cavity 1
Product is ejected, then manually regrinding-material 2 is cut or cut away from product using manual mode, this mode is specific
When implementation there are it is following the shortcomings that.
First, manually its production efficiency is cut or cut away to regrinding-material 2 than relatively low from product using manual mode,
Need to coordinate large number of worker to complete at the same time, secondly, the mode of handwork is influenced by worker itself factor
It is more, the different situation of like products regrinding-material cut out portion size, round and smooth degree shearing quality often occurs, and this is to pass
The major defect of system technology.
Utility model content
The utility model provides a kind of rotation mouth of a river resectoscope, it automatically can shear injection moulding regrinding and be carried with reaching
High production rate, lifts the effect of product quality, and this is the main purpose for the utility model.
Technical solution is used by the utility model：One kind rotates mouth of a river resectoscope, it includes shearing pipe, action gear
And drive ring, wherein, which fixes the bottom for being set in the shearing pipe, is provided with the action gear outer surface outer
Screw thread, the drive ring include outer ring body and inner ring body, which has an inner cavity, are provided with the inner surface of the inner cavity interior
Screw thread, the action gear are arranged in the inner cavity, meanwhile, the external screw thread of the action gear is mutually nibbled with the internal thread of the inner cavity
Close, which is located at the inner ring body surrounding, and motor gear is meshed with the outer ring body, which fixes and be set in electricity
On the power output shaft of machine, which is recessed with an injection molding cavity, which, which has, tilts inner ring surface and inner bottom surface,
The inner bottom surface is connected to the bottom of the inclination inner ring surface, and the outer surface at the top of the inclination inner ring surface with the shearing pipe crosses to form one
Ring edge is sheared, the angle between the inclination inner ring surface and the outer surface of the shearing pipe is less than 45 degree.
The shearing pipe is threaded through in rear cavity, offers injection molding channel at the top of the rear cavity, the note in the shearing tube top portion
Modeling chamber is connected with the injection molding channel, and when work, injection material enters in the injection molding cavity from top to bottom first, then flows
Enter into the injection molding channel and formed product carried out at the top of the rear cavity, after formed product can in the injection molding cavity and
Regrinding-material is formed above the shearing ring edge, this moment, which drives the motor gear to rotate, and drives the outer ring body to rotate, by
It is arranged in the inner ring body in the outer ring body, so the inner ring body drives the shearing pipe to rotate rising this moment, and by this
Shearing ring edge shearing regrinding-material makes regrinding-material be separated with product, to have the function that the automatic shearing mouth of a river, exists so as to save product
Secondary regrinding-material excision processing after injection, and avoid manual excision from bringing low production efficiency, excision quality cannot protect
The problem of barrier.
When specific implementation, which offers centre hole, is offered on the inner bottom surface of the injection molding cavity
Perforation, perforation connection are arranged between the injection molding cavity and the centre hole, are provided with thimble in the centre hole, which includes pin
Body and top, the top are fixed at the top of the needle body, wherein, which is arranged on the centre hole, which is threaded through
In the perforation, which is fixed on ejector retainner plate, should after the shearing pipe, which rotates, rises the action for completing the shearing mouth of a river
Ejector retainner plate action makes the top be ejected from the perforation, to have the function that the regrinding-material that will be shear off releases the injection molding cavity.
The beneficial effects of the utility model are：When utility model works, which drives the motor gear to rotate,
And drive the outer ring body to rotate, since the inner ring body is arranged in the outer ring body, so the inner ring body drives this to cut this moment
Pipe Cutting, which rotates, to be risen, and regrinding-material is separated with product by shearing ring edge shearing regrinding-material, to reach the automatic shearing mouth of a river
Effect so that save product after the injection-moulding secondary regrinding-material excision processing, and avoid manual excision bring production effect
The problem of rate is low, and excision quality cannot ensure.

Embodiment
As shown in Figures 2 to 4, a kind of to rotate mouth of a river resectoscope, it includes shearing pipe 10, action gear 20 and drive ring
30, wherein, which fixes the bottom for being set in the shearing pipe 10.
External screw thread is provided with 20 outer surface of action gear, which includes outer ring body 31 and inner ring body 32.
The inner ring body 32 has an inner cavity, and internal thread is provided with the inner surface of the inner cavity.
The action gear 20 is arranged in the inner cavity, meanwhile, this of the external screw thread of the action gear 20 and the inner cavity are interior
Screw thread is meshed.
31 ring of outer ring body is located at 32 surrounding of inner ring body.
Motor gear 33 is meshed with the outer ring body 31, which fixes the power output shaft for being set in motor 34
