Abstract
The utility model discloses a kind of cable vitta extrusion dies, the extruding end of its internal model is set with external mold inner sleeve and external mold housing from the inside to the outside, external mold housing tube wall is provided with the first vitta injecting hole, the setting of external mold outer casing inner wall is fluted, external mold inner sleeve tube wall is provided with the second vitta injecting hole, and the first vitta injection centerline hole, the center line of groove and the second vitta injection centerline hole overlap.Annular groove forms vitta extruded stock chamber so that vitta extrusion pressure is uniform；It adjusts external mold inner sleeve and can conveniently adjust vitta position；If desired increase vitta quantity, without increasing vitta extruder head, it is only necessary to increase injecting hole in external mold inner sleeve, it is very convenient.
Description
Technical field
The utility model is related to cable production equipment, more particularly to a kind of cable production China and foreign countries are molded into modeling vitta extrusion die
Tool.
Background technology
For the homochromy core wire in cable core is made easily to distinguish, common mode is to fill one or more its on homochromy core wire
The vitta of his color, vitta must squeeze out simultaneously with core wire true qualities, and vitta squeezes out necessary uniformity, does not influence core wire globality
Energy.The external mold of traditional vitta extrusion die is provided with injecting hole, and directly vitta is expressed on product by external mold injecting hole.By
It is easily fluctuated in vitta extrusion pressure, vitta is caused to squeeze out uneven, and vitta position is just completely solid after mold machine-shaping
It is fixed.During if necessary to change vitta position, then need to re-work making extrusion die, when needing to increase vitta quantity,
Injecting head and injecting hole must also be increased, die manufacturing cost increases, and very inconvenient.
Utility model content：
A kind of Novel cable vitta extrusion die of design of the utility model so that vitta extrusion pressure is uniform, facilitates color
Position is adjusted and vitta quantity increases.
To achieve the above object, the utility model uses following technical scheme.Cable vitta extrusion die, including internal model,
External mold housing and external mold inner sleeve, the extruding end of internal model are set with external mold inner sleeve and external mold housing, external mold housing tube wall from the inside to the outside
The first vitta injecting hole is provided with, the setting of external mold outer casing inner wall is fluted, and external mold inner sleeve tube wall is provided with the second vitta injecting hole,
First vitta injection centerline hole, the center line of groove and the second vitta injection centerline hole overlap.
Further, the second vitta injecting hole is at least one.
The utility model annular groove forms vitta extruded stock chamber so that vitta extrusion pressure is uniform, adjusts external mold inner sleeve
It can conveniently adjust vitta position.If desired increase vitta quantity, without increasing vitta extruder head, it is only necessary in external mold inner sleeve
Upper increase injecting hole, it is very convenient.

Fig. 3 is the structure sectional view of external mold inner sleeve 3 in the utility model.
In figure:1- internal models, 2- external mold housings, 3- external mold inner sleeves, 4- the first vitta injecting holes, 5- grooves, the second vittas of 6-
Injecting hole.
Specific embodiment
Below in conjunction with drawings and examples, the utility model is described in further detail.Referring to Fig. 1 to Fig. 3, cable vitta squeezes
Go out mold, including internal model 1, external mold housing 2 and external mold inner sleeve 3, which is characterized in that the extruding end of internal model 1 is set with from the inside to the outside
External mold inner sleeve 3 and external mold housing 2,2 tube wall of external mold housing are provided with the first vitta injecting hole 4, and setting is fluted in external mold housing 2
5,3 tube wall of external mold inner sleeve is provided with the second vitta injecting hole 6,4 center line of the first vitta injecting hole, the center line of groove 5 and
Two vitta injecting holes, 6 center line overlaps.The second vitta injecting hole 6 is at least one.
Entire vitta extrusion die is made of internal model 1 and external mold housing 2 and external mold inner sleeve 3, there is vitta injecting hole on external mold 2
4,2 inner wall recessing 5 of housing, external mold inner sleeve 3 has the second vitta injecting hole 6, the first vitta injecting hole 4, groove 5 in extrusion
It is completely superposed with 6 center line of the second vitta injecting hole.
Extrusion external mold is divided into two parts and formed by the utility model, respectively external mold housing 2 and external mold inner sleeve 3, outside external mold
It covers 2 inner walls and is provided with an annular groove 5, groove 5 is connected with the first vitta injecting hole 4, the color that external mold inner sleeve 3 is molded as needed
Quantity trepanning, vitta injected plastics material are expressed to groove 5, then squeeze through groove 5 through the first vitta injecting hole 4 on external mold housing 2
The second vitta injecting hole 6 of external mold inner sleeve 3 is pressed onto, then is molded into product surface through the second vitta injecting hole 6 and forms vitta.
It, should be according to extruding machine and extruded product it needs to be determined that mold overall dimensions, internal model 1 is with passing when the utility model makes
Internal model 1 of uniting is identical, and external mold is made of two parts, respectively external mold housing 2 and external mold inner sleeve 3, first determines external mold housing 2
After the first vitta injecting hole 4 is drilled, an annular groove 5, groove are opened in the inner wall of external mold housing 2 for first vitta injecting hole, 4 position
5 center lines are overlapped with 4 center line of the first vitta injecting hole, and injection vitta quantity opens the second vitta note to external mold inner sleeve 3 as needed
Mole 6, external mold inner sleeve 3 and 2 fitted position of external mold housing are fitted close, by step ensure in extrusion external mold inner sleeve 3 with
External mold housing 2 is connected as a single entity, 4 center of the first vitta injecting hole of external mold inner sleeve 3 and 5 center line of annular groove of external mold housing 2
It overlaps.
