The electric wire eye mould that is easy to change
Technical field
The utility model relates to a kind of equipment of making electric wire, is specifically related to a kind of electric wire eye mould that is easy to change.
Background technology
Present electric wire eye mould, as shown in Figure 1, comprise a circular external eye model 1, external eye model 1 middle part is provided with a round platform hole 11, comprise that also one is fixedly mounted on external eye model 1 central circular internal eye model 2, internal eye model 2 tops are round platforms 21, and the round platform hole 11 of round platform 21 and described external eye model 1 cooperates the formation one corridor section 3 that allows melted material 6 pass through, internal eye model 2 middle parts are provided with an inner chamber 22 that can allow electric wire heart yearn 4 pass through, and inner chamber 22 tops offer one and allow electric wire heart yearn 4 pass to enter the through hole 23 of described corridor section 3; During use, the diameter of the outlet in the round platform hole 11 of outer eye mask 1 (that is: corridor section outlet) diameter decision wire covering materials, when reality is used, owing to need the clad material of different-thickness, when changing, just need to change different external eye models like this, and change external eye model at every turn, and all need to carry out the work of aligning, use trouble.
The utility model content
The utility model purpose is: overcome the defective of prior art, provide a kind of easy to use, when needing the clad material of different-thickness, can carry out the electric wire eye mould that is easy to change of aligning.
The technical scheme that utility model provides is as follows: a kind of electric wire eye mould that is easy to change, comprise a circular external eye model, the external eye model middle part is provided with a round platform hole, comprise that also one is fixedly mounted on external eye model central circular internal eye model, the internal eye model top is a round platform, the round platform hole of round platform and described external eye model cooperates the formation one corridor section that allows melted material pass through, the internal eye model middle part is provided with an inner chamber that can allow the electric wire heart yearn pass through, interior top of chamber offers one allows the electric wire heart yearn pass the through hole that enters described corridor section, also include one and the circular cover die that is threaded of external eye model, the cover die middle part offers one and the forming through hole that communicates of described corridor section.
As preferably, in the above-mentioned electric wire eye mould that is easy to change, the forming through hole at described cover die middle part is a round platform hole.
The utlity model has following advantage: eye mask outside outside original, install a cover die additional, one forming through hole that is connected with corridor section in the external eye model is arranged therein, because cover die and external eye model are to be threaded, only need to change different cover dies, change the outlet diameter of forming through hole in the cover die, just can change the thickness of clad material, having exempted in the traditional design when changing external eye model need be to the work of external eye model aligning, easy to use, raises the efficiency.

Embodiment
Below in conjunction with accompanying drawing concrete execution mode is illustrated:
As shown in Figure 2, a kind of electric wire eye mould that is easy to change, comprise a circular external eye model 1, the external eye model middle part is provided with a round platform hole 11, comprise that also one is fixedly mounted on external eye model 1 central circular internal eye model 2, internal eye model 2 tops are round platforms 21, the round platform hole 11 of round platform 21 and described external eye model 1 cooperates the formation one corridor section 3 that allows melted material 6 pass through, internal eye model 2 middle parts are provided with an inner chamber 22 that can allow electric wire heart yearn 4 pass through, inner chamber 22 tops offer one and allow electric wire heart yearn 4 pass to enter the through hole 23 of described corridor section 3, also include one and the circular cover die 5 that is threaded of external eye model 1, cover die 5 middle parts offer one and the communicate forming through hole 51 of 3 circular platform type of described corridor section.
Of the present utility model installing and using as shown in Figure 3, comprise a head 7, include a L type circular hole 71 in the head 7, the Horizontal Exit of L type circular hole 71 offers a pit 72, described external eye model 1 is installed in the pit 72, and the end face of the Horizontal Exit of L type circular hole 71 is installed with the fixing external eyes supporting ring 74 of external eye model 1 horizontal level by screw 73; In the horizontal ends of L type circular hole 71 internal eye model 2 that extends described head 7 is installed, the inner chamber 22 that electric wire heart yearn 4 passes internal eye model 2 outwards continues to extend by forming through hole 51 backs of described corridor section 3 and cover die 5 successively; The sidewall of described pit 72 is equipped with one, and to be used to reconcile external eye model 1 and interior eye mask 2 coaxial to guarantee electric wire heart yearn 4 and the concentric aligning screw 75 of clad material.
During use; only need add melted material 6 endlessly in the vertical end of the L of head 7 type circular hole 71; melted material 6 can be full of the forming through hole 51 of described L type circular hole 71, corridor section 3 and cover die 5; travel forward and electric wire heart yearn 4 continues not stop; melted material 6 can be attached on the electric wire heart yearn 4 and travel forward; through after the forming through hole, form certain thickness coating protective layer and be wrapped in electric wire heart yearn 4 and come out, just formed electric wire commonly used on the market through the refrigerating work procedure of back.
Certainly, above embodiment just is explanation rather than restriction the utility model, as: as described in forming through hole in the cover die can be the round platform hole, also can be through hole; Described cover die can be an internal thread, and external eye model is an external screw thread, also can be the cover die external screw thread, the external eye model internal thread; Or the like ... such conversion all falls within the protection range of the present utility model.
