Description
Technical field
The present invention relates to a kind of charging pile cable cover(ing) plsitive molds, belong to cables manufacturing production equipment technology.
Background technique
Charging pile cable is a kind of new energy cable in power industry, charging pile cable be generally used in charging station,
The regions such as parking lot, hotel, villa, cell, garage are subjected to wind and weather, day at sudden and violent night trembles with fear, frost and snow in use for a long time
The erosion of the natural conditions such as frost, ultraviolet light, ozone, so charging pile cable should meet water-fast, oil resistant, acid and alkali-resistance, resistance to height
Warm, wear-resisting, anti-UV, cracking resistance, flame retardant property are good etc. to require and meets the properties such as uvioresistant, ozone, high-low temperature resistant.
By the rational design to the construction of cable, the insulation of soft and high-strength, high-anti-friction special cable and sheath material are selected, ensure that
The reliability (- 40 DEG C of environment temperature ~ 50 DEG C) of every power transmission of the automobile charging system actual with cable under normal operation circumstances,
Solve the problems, such as that performance declines under the long-term moving condition of automobile charging system actual cable.The sheath material because its fill out agent type compared with
More, the production technology performance of material is poor, and extrusion temperature difficulty control, rough phenomenon occurs often.In addition, cable core
Structure is complicated, and core is not rounded, leads to occur a large amount of quality problems during sheathing, if structure size is unqualified, table
Face stranding line is serious, and surface ring crude has the problems such as particle.
It produces charging pile cable and oversheath is produced using 90 extruding machine of Ф, have two molds with the coordinative composition of equipments, respectively
Plsitive mold and tubular molding tool, using effect is unsatisfactory at present.When squeezing out sheath using tubular molding tool, stranding line is tight
Weight squeezes sheath after tubular type squeezes out and easily forms blank pipe because material draftability is poor, and muscle is played on surface when leading to online chip bending, and at
Cable line is than more serious；When squeezing out sheath using plsitive mold, surface stranding line makes moderate progress, but due to pressure relief after squeezing out
And the factors such as cooling meat, structure size is still difficult to guarantee, therefore how to be produced the higher sheath of mass and become technology people
Member needs the target studied.
Summary of the invention
The object of the present invention is to provide a kind of charging pile cable cover(ing) plsitive mold, the charging pile cable cover(ing) squash types
Mold can preferably control pressure of the material when squeezing out, and reduce the friction of material Yu die sleeve mouth, solve the prior art
Middle stranding line is serious, and the surface quality problems such as muscle are played on surface.
In order to achieve the above objectives, the technical solution adopted by the present invention is that: a kind of charging pile cable cover(ing) plsitive mold, packet
Die sleeve and the mold core on the inside of die sleeve are included, the mold core has one to go out material through hole, and the die sleeve front end is provided with a die sleeve and holds
Diameter, this die sleeve hold that diameter is located at the front end of mold core and there are gap, the outer surface of the mold core and the interior tables of die sleeve between mold core
Face is the conical surface, and the angle that two conical surfaces are formed is 3 ° ~ 4 °, and the outer surface of the mold core and the inner surface of die sleeve form a charging
Channel.
Further improved scheme is as follows in above-mentioned technical proposal:
1. in above scheme, the height that the die sleeve holds diameter is 2mm.
2. in above scheme, the outer surface of the mold core and the inner surface shape of die sleeve are angled 3.5 °.
3. in above scheme, the caliber size of the material through hole out is less than the caliber size that die sleeve holds diameter.
4. in above scheme, the mold core and die sleeve hold the gap between diameter as 2 ~ 5mm.
Due to the application of the above technical scheme, compared with the prior art, the invention has the following advantages:
1, charging pile cable cover(ing) plsitive mold of the present invention, the mold core including die sleeve and on the inside of die sleeve, the mold core tool
There is one to go out material through hole, the die sleeve front end is provided with a die sleeve and holds diameter, this die sleeve hold diameter be located at mold core front end and with mold core it
Between there are gap, the outer surface of the mold core and the inner surface of die sleeve are the conical surface, and the angle that two conical surfaces are formed is 3 ° ~ 4 °,
The outer surface of the mold core and the inner surface of die sleeve form a feeding-passage, can preferably control pressure of the material when squeezing out
Power reduces the friction of material Yu die sleeve mouth, solves in the prior art that stranding line is serious, and surface is played the surface quality such as muscle and asked
Topic, while the requirement of structure size stability is also met, improve the quality of product.
2, charging pile cable cover(ing) plsitive mold of the present invention, the height that die sleeve holds diameter is 2mm, and personnel are real after study
Multiple experiment and improvement in the production of border, the height of 2mm both will not reduce material and squeeze because of the too long friction increased to die sleeve mouth
In the pressure of die sleeve mouth when out, the problem of crude, ring will not occur because of shorter；In addition, outer surface and the mould of its mold core
The inner surface shape of set is angled 3.5 °, and the size of angle is also the trial and improvement that personnel are multiple after study, will be original
5 ° are reduced to 3.5 °, and the size of angle directly affects the size of injection pressure, the pressure for reducing angle when can guarantee material extrusion
Power is stably and controllable, so that solving extruding layer ring, stranding line and outer diameter shakiness and other issues easily occurs, also avoids because of angle
Degree is too small to cause stress too small the phenomenon that leading to blank pipe；In addition, it is 2 ~ 5mm that its mold core and die sleeve, which hold the gap between diameter, reserve
The gap of certain distance helps to control pressure when plastics enter mold core and die sleeve, and pressure controllable facilitates into the cable of output
Formation effect is good, and stranding line is few, and sheath is close.
