The feature of the terms such as " third ", " the 4th " can explicitly or implicitly include at least one of the features.In description of the invention
In, the meaning of " plurality " is at least two, such as two, three etc., unless otherwise specifically defined.
The embodiments described below with reference to the accompanying drawings are exemplary, it is intended to be used to explain the present invention, and cannot understand
For limitation of the present invention.Each technical solution of the invention is described in detail below with reference to specific embodiment.
Puncture core bar of the invention has segmentation structure, to enable to curved lever in each section of injection molding
It reserves enough length to be positioned, and reserved part can be used in carrying out the positioning of curved lever, to overcome existing
It punctures in core bar manufacturing method, the problem of curved lever is easy to happen offset.
As shown in Figure 1, 2, in the technical scheme, the shaft for puncturing core bar is divided into two sections of settings.Specifically, the puncture
Core bar includes: tip 10, the first shaft 20 and the second shaft 30.
First shaft 20 has first end 21 and second end 22, and the first end 21 is connected with the tip 10,
And it is integrally formed with the tip 10.Preferably, first shaft 20 by way of injection molding with 10 one of the tip at
Type.
Second shaft 30 has third end 31 and the 4th end 32, the second end 22 of first shaft 20 and described the
The third end 31 of two shafts 30 is fixedly connected, described in order to guarantee the secured connection between the first shaft 20 and the second shaft 30
First end 21 is provided with several first connection structures 23, and the third end 31 is provided with several to be matched with the first connection structure 23
The second connection structure 33.Specifically, several first connection structures 23 are several spaced first protrusions, described the
Two connection structures 33 are the second protrusion matched with first protrusion.In addition, the 4th end 32 of second shaft 30 is set
It is equipped with auxiliary and punctures the installation end 34 that core bar carries out installation fixation in puncture outfit.
When first shaft 20 is connected with the second shaft 30, the first protrusion and the second protrusion are staggered, thus, the
One shaft 20 and the second shaft 30 are attached in a manner of being fitted into each other, so that, the first shaft 20 and the second shaft 30
Between have biggish contact area, and due to first protrusion the second protrusion between interaction force, limit the first bar
The relative motion of body 20 and the second shaft 30 on axially and tangentially, to both ensure that the fastness of connection.Wherein, described
Tangentially refer to and 30 plane tangent of the first shaft 20 and the second shaft, and the axial direction with first shaft 20 and the second shaft 30
With radial perpendicular direction.
Further, second shaft 30 is carried out by way of injection molding with the second end 22 of first shaft 20
Fusion connection.The fusion connection refers to, after the molding of the first shaft 20, the second end 22 of first shaft 20 is extend into
In the injection die cavities of second shaft 30, the second shaft 30 realizes second with first shaft 20 while injection molding
The fusion connection at end 22.After first shaft 20 and the molding of the second shaft 30, since the first protrusion and the second protrusion are staggered, make
Obtaining has biggish contact area between the first shaft 20 and the second shaft 30, in injection molding fusion process, 20 He of the first shaft
The active area that second shaft 30 carries out fusion connection is also larger, to further ensure stability when the two connection and company
Fastness after connecing.Further, since the molding mode of the first shaft 20 and the second shaft 30 using segmentation injection molding, the first shaft 20
With the second shaft 30 it is respectively separately formed during, internal curved lever has the located space of sufficient length, thus, avoid
Curved lever shifts, so that puncturing core bar injection molding quality with higher.It should be noted that as needed, first
Shaft 20 and the second shaft 30 can also be used the mode assembled after cooling and shaping respectively and installed.
As shown in Fig. 2, in one embodiment, several first protrusions and several second protrusions are arranged as follows:
Several first protrusions are evenly distributed along the circumferential direction of the second end 22 of first shaft 20, correspond ground, Ruo Gansuo
It is evenly distributed to state circumferential direction of second protrusion along the third end 31 of second shaft 30.In addition, any first protrusion is from described the
On the end face of one shaft 20, it is integrally formed along the axial direction of first shaft 20 and first shaft 20；Any second
Protrusion from the end face of second shaft 30, along second shaft 30 axial direction and second shaft, 30 one at
Type.
The peripheral surface of first protrusion and the peripheral surface of first shaft 20 are flush, thus, described first
Protrusion is curved surface with the surface that the first shaft 20 is flush.Specifically, the shape of first protrusion can be semicircle, half ellipse
Round, regular polygon or abnormal curved surface.Wherein, the abnormal curved surface refers to feelings when first protrusion has irregular shape
Shape.It should be noted that illustrating only the situation that the first protrusion is rectangle in Fig. 2, the situation of other shapes is not shown.
As shown in figure 3, in one embodiment, first protrusion includes the when first protrusion is abnormal curved surface
One ontology 230 and at least one clamping part 231, the first noumenon 230 are set along the axial direction extension of first shaft 20
It sets, the clamping part 231 is arranged from the side projection of the first noumenon 230；.By the way that the clamping part 231, Neng Goujin is arranged
One step limits the movement of first protrusion and the second protrusion in the axial direction.Correspondingly, the shape of second protrusion
The shape in gap between two adjacent the first protrusions is corresponding.
As shown in figure 4, in another embodiment, first protrusion includes when first protrusion is abnormal curved surface
Second ontology 232 and at least one recessed portion 233, second ontology 232 extend along the axial direction of first shaft 20
Setting, the two sides of recessed portion 233 from the first noumenon are recessed inwardly setting.It, can by the way that the recessed portion 233 is arranged
Further limit the movement of first protrusion and the second protrusion in the axial direction.Correspondingly, the shape of second protrusion
The shape in gap between shape and the first adjacent protrusion is corresponding.
Based on the same technical idea, the present invention also provides a kind of puncture core bars of segmented, which includes: point
End, the first shaft ..., the i-th shaft ..., the n-th shaft, the n is positive integer more than or equal to 3.To at this
In technical solution, the shaft for puncturing core bar is at least divided into three sections of settings.
