The element that same or similar label represents same or similar element or has same or like function.
In describing the invention it is to be understood that term " " center ", " longitudinal ", " horizontal ", " length ", " width ",
" thickness ", " on ", D score, "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outward ", " axle
To ", " radially ", " circumferential ", the orientation of the instruction such as " reciprocal " or position relationship be based on orientation shown in the drawings or position relationship,
Be for only for ease of the description present invention and simplify description, rather than instruction or the hint device of indication or element must have specific
Orientation, with specific azimuth configuration and operation, be therefore not considered as limiting the invention.
Additionally, term " first ", " second " are only used for describing purpose, and it is not intended that indicating or hint relative importance
Or the implicit quantity indicating indicated technical characteristic.Thus, define " first ", the feature of " second " can express or
Implicitly include at least one this feature.In describing the invention, " multiple " are meant that at least two, such as two, three
Individual etc., unless otherwise expressly limited specifically.
Embodiment below with reference to Description of Drawings is exemplary it is intended to be used for explaining the present invention, and is not understood that
For limitation of the present invention.With reference to specific embodiment, each technical scheme of the present invention is described in detail.
As shown in Figures 1 to 3, the puncture core bar manufacture method of the present invention comprises the steps:
S1, offer puncture the shaft 1 of core bar, one end of described shaft 1 is sent in the die cavity 2 of injection mold, controls note
The curved lever 3 of mould so as to passing through described shaft 1 and stretching in described die cavity 2, or, first curved lever 3 is passed through described bar
Body 1, more described shaft 1 and curved lever 3 are together sent in the die cavity 2 of injection mold.
Wherein, the described shaft 1 puncturing core bar is hollow steel pipe, and this hollow steel pipe insertion setting, and its one end is used
In with puncture core tip 4 be connected.Preferably, described hollow steel pipe is processed by drawing process, so obtained sky
Heart steel tube surface quality preferably, meets the use standard of perforator.
Described curved lever 3 is used for the injection mo(u)lding that auxiliary punctures core tip 4, and it stretches into the described die cavity of described injection mold
The shape of the part in 2 is corresponding with the outer contoured shape at the puncture core tip 4 of molding, i.e. die cavity 2 and its internal molding
Space between bar 3 forms the injection mo(u)lding space puncturing core tip 4 front portions.So that curved lever 3 can pass through described bar
Body 1, and extend in the die cavity 2 of described injection mold, the length of described curved lever 3 is more than the length of described shaft 1.
S2, injection mold carry out matched moulds, and described shaft 1 and curved lever 3 are positioned, and keep described curved lever 3 He
There is between the inwall of shaft 1 spacing of 0.01mm～0.02mm.
After injection mould closing, under the pressing effect of shaft 1 and curved lever 3 detent mechanism in mould, realize positioning.Right
When described shaft 1 and curved lever 3 are positioned, described shaft 1 and curved lever 3 keep being coaxially disposed, i.e. shaft 1 and curved lever 3
Central axis coincide.The technological parameter setting when the molecular diameter according to injection molding material and injection is (as injection molding material flow velocity, injection
Temperature, injection pressure, molding cycle etc.), have between 0.01mm～0.02mm between described curved lever 3 and the inwall of shaft 1
Away from.It is arranged such, both ensure that when being subsequently implanted into injection molding material, injection molding material will not enter between curved lever 3 and the inwall of shaft 1
Space in, after making injection mo(u)lding, curved lever 3 can smoothly depart from again.
S3, by the injection hole of injection mold, in described die cavity 2 inject injection molding material, carry out puncture core tip 4 injection
Molding, described injection hole is located at the side of described shaft 1, and injection molding material is through pressurize, cooling aftershaping, sharp by the puncture core after molding
End 4 carries out the demoulding.
Wherein, described injection hole is opened on the medial wall of described die cavity 2, and is located at the shaft 1 entering in described die cavity 2
Side.So, when injecting injection molding material, injection molding material is relative to shaft 1 from laterally entering die cavity 2.Because puncturing core tip 4
Front end is the effect end being punctured, and it is higher to injection mo(u)lding prescription, thus, during the demoulding, the note of residual at injection hole
Plastics will not form projection puncturing the most advanced and sophisticated front end of core, it is to avoid adversely affect to puncturing the most advanced and sophisticated front end of core, thus
The injection quality that puncture core tip 4 has been effectively ensured.
Further, when injecting injection molding material, can be using the injection molding manner of unidirectional injection or two-way injection.Described injection note
When plastics adopt unidirectional injection, the quantity of described injection hole at least 1, described injection hole is opened in the inner side of described die cavity 2
On wall, and it is located at the side of described shaft 1.In order to improve the efficiency of injection, described injection injection molding material may also be employed two-way injection
Mode, now, the quantity of described injection hole is at least more than 2 even number, and described injection hole is opened in the inner side of described die cavity 2
On wall, and it is symmetrically located at the both sides of described shaft 1.
Based on described puncture core bar manufacture method, the present invention also provide a kind of puncture core bar, it is by puncturing as above
Core bar manufacture method is fabricated by.
Based on described puncture core bar, the present invention also provides a kind of perforator, and it includes puncturing as above core bar.
In sum, the puncture core bar manufacture method of the present invention, by the way of lateral injection injection molding material, is effectively ensured
Puncture the most advanced and sophisticated injection quality of core.Additionally, the core bar manufacture method that punctures of the present invention is passed through to control curved lever and is punctured core bar
Spacing between the inwall of shaft, had both been enable shaft to be efficiently separated with curved lever, and it can be avoided that injection molding material had entered
Enter in the space between shaft and curved lever.
