The present invention is further elaborated.
Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
Fig. 2 shows the structure diagrams for the cable extruding mold that present pre-ferred embodiments propose.The present embodiment proposes
Cable extruding mold squash type can be realized by position of the metering needle tube body in internal model, tubular type is squeezed, half squeeze tubular type three
The conversion of the extrusion die of kind form, to be suitable for the expressing technique of different cable types and material.The mold squeezes out three kinds
The mold of form is integrated in one, can flexible conversion can simultaneously quantify to finely tune, convenient for cable research and development debug, can one module multiple usages, improve
The versatility of cable extruding mold, so as to reduce production cost.
Specifically, as shown in Figures 2 and 3, the cable extruding mold that the present embodiment proposes includes external mold 10, internal model 20, needle
Pipe 30.
Wherein, internal model 20 is nested and is coaxially disposed in external mold 10, has gap between internal model 20 and external mold 10, internal model
Die orifice end face 201 is located within the die orifice end face 101 of external mold.
Needle tubing 30 includes needle tubing ontology 303, the needle tubing caudal peduncle 302 being connect with needle tubing ontology, is provided in needle tubing ontology 303
For wearing the through-hole of the cable core of cable, the end face of the separate needle tubing caudal peduncle 302 of needle tubing ontology 303 is needle tubing mouth end face 301, interior
Film 20 is in axial direction provided with centre bore, and 303 rotary setting of needle tubing ontology is in the centre bore, when rotation needle tubing caudal peduncle 302
When, needle tubing ontology 303 is in the centre bore along the axial movement of internal model 20.
In the present embodiment, needle tubing ontology 303 may be used screw thread 306 with internal model 20 and connect.When it is implemented, can including
Internal thread is set on the die body of mould 20, the external screw thread 307 being adapted with internal thread is set on needle tubing ontology 303, so that needle tubing
Ontology 303 is rotatably connected with internal model 20.
In the present embodiment, when rotation needle tubing caudal peduncle 302 to needle tubing mouth end face 301 stretch out external mold die orifice end face 101 or
When being flushed with the die orifice end face 101 of external mold, cable extruding mold is tubular molding tool, when rotation needle tubing caudal peduncle 302 to needle tubing mouth
When end face 301 is retracted the die orifice end face 101 of external mold, cable extruding mold is half tubular molding tool, when needle tubing ontology 303 is rotated
When going out centre bore, cable extruding mold is plsitive mold.
For the ease of with spanner or other tool knob needle tubing caudal peduncles 302 with metering needle nozzle end face 301 and external mold
The cross section of needle tubing caudal peduncle 302 is set as outer hexagon by the relative position of die orifice end face 101, the present embodiment.
In addition, the present embodiment is evenly distributed with several ventilations in one end of the close needle tubing caudal peduncle 302 of needle tubing ontology 303
Slot 303 allows air to be uniformly passed in internal model 20, ensures mold inside and outside air pressure balance, and cable jacket is made to squeeze out rounding,
Outer diameter is stablized.
When it is implemented, 4 or 6 air channels can be uniformly arranged in threaded one end of tool of needle tubing caudal peduncle 302
308。
In addition, it is 1mm's that the present embodiment indicates scale division value at least one of several air channels 308 air channel 308
Graduated scale 305 can so quantify the length that the die orifice end face 101 of external mold is stretched out in metering needle nozzle end face 301, to be suitable for not
Same cable type and the expressing technique of material are debugged convenient for the research and development of cable, reduce the waste of modification mold.
In addition, the present embodiment has been evenly arranged several air holes 304 on needle tubing ontology 303, make outer space in needle tubing 30
Gas forms reflux, avoids leading to cable jacket hard-pressed bale on cable core because cable core enters at a high speed the generation of needle tubing 30 Bernoulli effect.
The distance that the present embodiment stretches out the die orifice end face 101 of external mold by increasing needle tubing mouth end face 301, increases extrusion molding
Length is isolated with cable core in sheath, can effectively solve the problems, such as cable sheath and cable core adhesion.
In conclusion the advantageous effect of cable extruding mold proposed by the present invention is：Cable extruding mold of the present invention passes through
Position of the metering needle tube body in internal model can realize squash type, squeeze tubular type, half squeeze the extrusion die of tubular type three kinds of forms
Conversion, to be suitable for the expressing technique of different cable types and material.The mold of three kinds of extrusion forms is integrated in one by the mold,
Can flexible conversion can simultaneously quantify to finely tune, convenient for cable research and development debug, can one module multiple usages, improve the general of cable extruding mold
Property, so as to reduce production cost.
The foregoing is merely the preferred embodiment of the present invention, are not intended to limit the scope of the invention, every utilization
Equivalent structure or the flow transformation that description of the invention and accompanying drawing content are made, are directly or indirectly used in other relevant skills
Art field, is included within the scope of the present invention.
