Embodiment
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
As Figure 1-5, a kind of mould for being used to manufacture the thin-walled tubular plastics with one end open, including be mutually adapted
Dynamic model and cover half, the cover half includes cover half body 1, and in this specific embodiment, cover half body 1 is square structure, certainly,
In other embodiments, cover half body 1 can also be the other structures such as tri-prismoid, cylinder.
The upper surface of the cover half body 1 is provided with a cavity, and the cavity includes the cylindrical upper cavity 11 being connected
With lower chamber 12, the diameter of the upper cavity 11 is more than the diameter of lower chamber 12, so as to form step-like cavity.Upper cavity 11
How much diameter can specifically be selected greatly than the diameter of lower chamber 12 according to being actually needed, and this is that those skilled in the art can be with
Realize, no longer describe in detail easily.
Be provided with electromagnet 14 in cover half body under the bottom of lower chamber 12, electromagnet 14 by reversing switch with
Power supply connects, and reversing switch is prior art, and this is no longer described in detail, and the magnetic pole of electromagnet 14 is setting up and down（I.e. with opening
Matched moulds direction is consistent）.Preferably, electromagnet 14 is close to the bottom of lower chamber 12.
The dynamic model includes dynamic model body 2, and in this specific embodiment, dynamic model body 2 is square structure, certainly, other
In embodiment, dynamic model body 2 can also be the other structures such as tri-prismoid, cylinder.
The lower surface of the dynamic model body 2 is provided with a lug boss, and the lug boss includes being connected cylindrical upper
Lug boss 21 and lower convex portion 22, the diameter of the upper projecting portion 21 is more than the diameter of lower convex portion 22, step-like so as to be formed,
The diameter of upper projecting portion 21 is equal to or slightly less than the diameter of upper cavity 11, thus punch-pin can be positioned, lower convex portion
22 diameter is less than the diameter of lower chamber 12, and the height of lower convex portion 22 is less than the height of lower chamber 12.
Magnet 23 is provided with lower convex portion 22, the magnetic pole of magnet 23 is setting up and down（It is i.e. consistent with open mold direction）, this tool
In body embodiment, magnet 23 is preferably magnet.Preferably, magnet 23 is close to the lower surface of lower convex portion 22.
When dynamic model and during cover half matched moulds, lower convex portion 22 be located at lower chamber 12 it is interior and with the composition type of inwall 12 of lower chamber
Chamber, magnet 23 is just relative with the magnetic pole of electromagnet 14, and certainly, in other embodiments, magnet 23 can also be set with electromagnet 14
The other positions in dynamic model and cover half are put, this is that those skilled in the art can realize easily, is no longer described in detail.Upper projection
Portion 21 is embedded and the lower surface of upper projecting portion 21 interior in upper cavity 11（That is step surface）With the lower surface of upper cavity 11（That is step
Face）It is brought into close contact, plastic liquid can be blocked, so as to one-shot forming, without trimming again, the cover half body 11 is provided with some
