Abstract
The utility model discloses a kind of three thread processing molds, including cylindrical body, the cylindrical body is axially arranged with the through-hole through its both ends along it, the inner wall of the through-hole is equipped with thread, and through-hole described in the upper edge of one of described cylindrical body end face is circumferentially uniformly provided with three grooves for transitting to the thread end.Three thread processing molds of the utility model are circumferentially uniformly distributed along through-hole using three and transit to the groove of thread end, in the thread in processing the mold, using this three grooves as starting point, so that the tooth of the thread in the mold is away from the tolerance reached in thread standard, so as to ensure that three thread plastic parts precision that the mold processes are higher.
Description
Technical field
The utility model is related to mould parts manufacturing technology fields, more particularly to a kind of three thread processing molds.
Background technology
The part of many plastic cement all carries the shape of thread, but the processing of plastic cement thread is one of plastic mould processing
Exigent product, process is extremely complex, to the required precision higher of mould parts, because of the direct shadow of the size of part
Ring the size to product.At present injection mold, die casting thread forming technique can only ensure the major diameter of thread, path, logical
The required precision of no-go gage, for the plastic parts with three threads, it cannot be guaranteed that the precision of processing.
In view of the above shortcomings, the designer, is actively subject to research and innovation, to found a kind of three thread processing moulds
Tool makes it with more the utility value in industry.
Utility model content
The purpose of this utility model is that proposing a kind of three thread processing molds, process three spiral shells are enabled to
Tooth plastic parts precision is higher.
For this purpose, the utility model uses following technical scheme：
A kind of three thread processing molds, which is characterized in that including cylindrical body, the cylindrical body is axially arranged with along it
The inner wall of through-hole through its both ends, the through-hole is equipped with thread, and described in the upper edge of one of described cylindrical body end face
Through-hole is circumferentially uniformly provided with three grooves for transitting to the thread end.
Further, the cylindrical body includes integrally formed first cylinder and the second cylinder, first cylinder
Outer diameter is less than the outer diameter of second cylinder, and forms positioning step between first cylinder and second cylinder.
Further, the outer wall of second cylinder is equipped with direction positioning surface.
Further, the plane where the direction positioning surface and the outer wall of first cylinder are tangent.
Further, there is spacing between the end corresponding with the through-hole of end of the thread far from the groove.
Further, the spacing be more than the thread tooth away from.
The beneficial effects of the utility model are：It is circumferentially uniformly distributed along through-hole using three and transits to the recessed of thread end
Slot, in the thread in processing the mold, using this three grooves as starting point so that the tooth of the thread in the mold is away from reaching spiral shell
Tolerance in tooth standard, so as to ensure that three thread plastic parts precision that the mold processes are higher.
Description of the drawings
Fig. 1 is the structural schematic diagram for three thread processing molds that specific embodiment of the present invention provides；
Fig. 2 is the front view for three thread processing molds that specific embodiment of the present invention provides；
Fig. 3 is sectional views of the Fig. 2 along line A-A.
In figure：The first cylinders of 10-, the second cylinders of 20-, 30- through-holes, 40- threads, 50- grooves, 60- positioning steps, 70-
Direction positioning surface.
Specific implementation mode
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
As shown in Figures 1 to 3, three thread processing molds of the utility model include by the first cylinder 10 and the second cylinder 20
The cylindrical body being integrally formed to, cylindrical body are axially arranged with the through-hole 30 through its both ends along it, and the inner wall of through-hole 30 is equipped with
Thread 40, and circumferentially be uniformly provided with three transits to the recessed of 40 end of thread to one of cylindrical body end face upper edge through-hole 30
Slot 50.The utility model, along the circumferential groove 50 for being uniformly distributed and transitting to 40 end of thread of through-hole 30, is being processed using three
It is starting point with this three grooves 50 when thread 40 in the mold so that the tooth of the thread 40 in the mold is away from reaching thread
Tolerance in standard, so as to ensure that three thread plastic parts precision that the mold processes are higher.
Specifically, the outer diameter of the first cylinder 10 is less than the outer diameter of the second cylinder 20, and in the first cylinder 10 and the second cylinder
Positioning step 60 is formed between 20.The mold can be navigated on process equipment using positioning step 60.
In order to further navigate to cylindrical body on lathe, the outer wall of second cylinder 20 of the utility model is equipped with side
Plane and the outer wall of the first cylinder 10 to positioning surface 70, and where direction positioning surface 70 is tangent.Utilize direction positioning surface 70
It can be when processing thread 40 to positive direction, convenient for determining the axial position between electrode and lathe；In addition, making direction positioning surface 70
The plane at place and the outer wall of the first cylinder 10 are tangent, can simplify the structure of the Installing machine tool cylindrical body.
For the ease of being inserted into electrode, the utility model stays a dead band in end of the through-hole 30 far from groove 50, the dead band
Inside without processing thread, that is, end of the thread 40 processed far from groove 50 has between end corresponding with through-hole 30
Have a spacing, and the spacing be more than the tooth of thread 40 away from.
To sum up, three thread processing molds of the utility model enable to process three thread plastic parts precision
It is higher.
The technical principle of the utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
With novel principle, and it cannot be construed to the limitation to scope of protection of the utility model in any way.Based on the explanation herein,
Those skilled in the art would not require any inventive effort the other specific implementation modes that can associate the utility model,
These modes are fallen within the scope of protection of the utility model.
