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.
As shown in Figure 1, the puncture core bar inner hollow setting comprising: tip 1, the first shaft 2 and the second shaft
3, wherein the tip 1 is located at one end of first shaft 2, and second shaft 3 is located at the another of first shaft 2
End.Preferably, the length of second shaft 3 is greater than the sum of the length at the tip 1 and the first shaft 2.
The manufacturing method of puncture core bar of the invention enables to curved lever reserved due to the molding mode using segmented
Enough length is positioned, and reserved part can be used in carrying out the positioning of curved lever, to overcome existing puncture
In core bar manufacturing method, the problem of curved lever is easy to happen offset.Specifically, the manufacturing method of puncture core bar of the invention includes
Following steps:
The production of S1, tip and the first shaft.
The step S1 punctures tip 1 and the first shaft 2 of core bar for production first.Due to second shaft 3
Length is greater than the sum of the length at the tip 1 and the first shaft 2, thus, in 2 production process of tip 1 and the first shaft, favorably
In the fixation for keeping positional relationship between tip 1 and the first shaft 2 and curved lever.Meanwhile curved lever and 3 phase of the second shaft
Corresponding part, can be used in the positioning of curved lever at this time, shift in this way, further avoiding curved lever.
As shown in Fig. 2, the step S1 is specifically included:
S11, by the part corresponding with the tip 1 and the first shaft 2 of curved lever 4, be sent into the of the first injection molding station
In one type chamber 5.
Wherein, the internal diameter of the first type chamber 5 is greater than the outer diameter of the curved lever 4, thus, the first type chamber 5 with into
Enter the injection molding space that the tip 1 and the first shaft 2 are limited between the curved lever 4 of the first type chamber 5.In addition, molding
The part corresponding with the tip 1 and the first shaft 2 of bar 4 refers to, on curved lever 4 for assist tip 1 and the first shaft 2 at
The part of type.
S12, the curved lever 4 is positioned, is fixed in position it with respect to the inner wall of the first type chamber 5.
Wherein, when being positioned to the curved lever 4, using the positioning mechanism in corresponding injection moulding apparatus to curved lever 4,
Part corresponding with second shaft 3 applies active force, and the curved lever 4 and the first type chamber 5 is made to keep coaxial arrangement.Institute
Rheme sets fixed be meant that: making curved lever 4 under the action of positioning mechanism of the locating rod 3 in injection moulding apparatus with described first
The inner wall holding position relationship of type chamber 5 is relatively fixed.
Specifically, the inner wall includes side wall 51 and antetheca 52, is had between the curved lever 4 and the side wall 51 radial
Distance, for curved lever 4 under detenting force, the radial distance between 5 injection die cavities 2 of curved lever 4 and the first type chamber keeps uniform
Unanimously, radial positioning is carried out to curved lever 4 to realize；There is axial distance between the curved lever 4 and the antetheca 52, at
For type bar 4 under detenting force, the axial distance between curved lever 4 and antetheca 52 keeps uniformity, to realize to molding
Bar 4 carries out axially position.
Further, since the tip 1 of injection molding and the opposite puncture core bar of the first shaft 2 are generally speaking, length is shorter, and at
The part that type bar 4 can be used for positioning is relatively long.In this way, curved lever 4 is not susceptible to deviate, it can guarantee the point of injection molding
The Forming Quality at end 1 and the first shaft 2.
S13, to injecting injection molding material between the first type chamber 5 and curved lever 4, injection molding material through pressure maintaining, it is cooling after form, will
Tip 1 after molding and the first shaft 2 are separated with the first type chamber 5.
Wherein, during tip 1 after molding and the first shaft 2 being separated with the first type chamber 5, curved lever is kept
4 are fixed in position with the tip 1 and the first shaft 2, in this way, in order to the injection molding of the second shaft 3.
As shown in figure 3, the production of S2, the second shaft.
S21, by the part corresponding with second shaft 3 of curved lever 4, be sent into the second type chamber 6 of the second injection molding station
In.
Wherein, the internal diameter of the second type chamber 6 is greater than the outer diameter of the curved lever 4, thus, the second type chamber 6 with into
Enter the injection molding space that second shaft 3 is limited between the curved lever 4 of the second type chamber 6.Meanwhile first shaft 2
End is also extend into second type chamber 6, is connected in order to be molded with the second shaft 3.In addition, the curved lever 4 and described second
The corresponding part of shaft 3 refers to, for assisting the molding part of the second shaft 3 on curved lever 4.
S22, the curved lever 4 is positioned, makes the side of its opposite tip 1 and the first shaft 2 and second type chamber 6
Wall is fixed in position.
Wherein, corresponding with the tip 1 and the first shaft 2 to curved lever 4 when being positioned to the curved lever 4
Part applies active force, and the curved lever 4 and second type chamber 6 is made to keep coaxial arrangement.Wherein, the position for applying active force is
It acts on the tip 1 outside curved lever 4 and the first shaft 2, thus, under the transmitting effect of power, active force can be applied to
On curved lever 4, and then realize the positioning of the curved lever 4.At this point, due to the opposite puncture core bar of the second shaft 3 of injection molding
Generally speaking, length is shorter, and to can be used for position portion relatively long for curved lever 4.In this way, curved lever 4 is not susceptible to deviate,
It can guarantee the quality of the second shaft 3 of injection molding.
S23, to injecting injection molding material between the second type chamber 6 and curved lever 4, injection molding material through pressure maintaining, it is cooling after form, it is right
Puncture core bar after molding is demoulded.
Wherein, the second shaft 3 is in second type chamber 6 when injection molding, and injection molding material is by being opened in 6 inner sidewall of second type chamber
Injection hole be injected into the second type chamber 6, the injection molding material of injection is in contact with the end of the first shaft 2, in injection molding material
Under heat effect, the end face of the first shaft 2 is merged with injection molding material, after 3 injection molding of the second shaft, the first shaft 2 with
Second shaft 3 is connected, and obtains completely puncturing core bar.
In addition, second injection molding station is continuously arranged with first injection molding station, alternatively, second injection molding station
It is separately positioned with first injection molding station.Wherein, when second injection molding station and first injection molding station are continuously arranged,
It can be realized by double coloured plastic injection machine, at this point, being sent to automatically at the first injection molding station tip after molding and the first shaft
Two injection molding stations carry out the injection molding of the second shaft.Second injection molding station and first injection molding station are separately positioned
When, two molds can be used and carry out injection molding respectively.
The present invention also provides a kind of manufacturing methods for puncturing core bar, in the manufacturing method of this puncture core bar, puncture core bar
Injection molding is not limited to two sections of injection moldings, can be as needed, completes to puncture according to the more multistage Shooting Techniques such as three sections, four sections
