Abstract
Adopt the present invention, can make HV cable accessories insulated part integral one-step molding, a mold can use liquid and two kinds of materials of solid simultaneously, each position uniform in shaping exhaust is unimpeded, and charging is young to be heated evenly, and has improved the stability of technology, simultaneously, because it is simple in structure, make mold design simple relatively, can omit vacuum extractor, the annex of global formation is because charging aperture is few in addition, overlap that is produced and tailing are also less, thereby have reduced cost.
Description
Technical field
The invention belongs to HV cable accessories and make the field, relate in particular to the forming method and the mould thereof that are used for the manufacturing of HV cable accessories insulated part.
Background technology
At present in the HV cable accessories manufacturing, what be used for fluid molding material is forming method and the mould of using left and right sides matched moulds, this method and mould have accomplishes have 110kV and above electric cable accessories as Chinese patent 03801986.8 " being used for protecting the coated semiconductor and the application process of elastomeric electrical cable accessories " mentioned; What be used for the solid material moulding is that this method and mould can only be accomplished 35kV and following electric cable accessories with the up and down forming method and the mould of matched moulds, and above-mentioned two kinds of methods and mould can not be taken into account the moulding of liquid and solid material simultaneously.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of forming method and mould thereof that the HV cable accessories insulated part is made that be used for is provided.
Technical scheme of the present invention is, a kind of forming method that is used for the manufacturing of HV cable accessories insulated part, use the mode of matched moulds up and down, it is characterized in that: when using the solid material moulding, from vertical mouthful and the bed die transverse holes charging of correspondence position of mold, from the transverse holes of bed die and vertically mouthful overflow exhaust, after sizing material is full of die cavity, pressure forms extrusion process from inside to outside, makes the interior air of cavity discharge; When using fluid molding material, from vertical mouthful and transverse holes charging of bed die, from a plurality of steam vent overflow exhausts of bed die transverse holes and mold, when the liquid material is full of die cavity, form the bulbs of pressure from inside to outside in the cavity, make the interior air of cavity discharge.
For realizing the mould that the HV cable accessories insulated part is made that is used for of said method, form by mold, bed die and core rod, the die cavity shape is the shape of HV cable accessories insulated part, it is characterized in that: the close end of mold has one group vertical mouthful, on the surface longitudinal axle of mold a plurality of steam vents is arranged; The vertically transverse holes of mouth of one group of correspondence is arranged on the bed die, and transverse holes communicates with die cavity, the vertical mouth that also has one group of transverse holes on the bed die and communicate with it, and transverse holes communicates with die cavity.
Adopt the present invention, can make HV cable accessories insulated part integral one-step molding, a mold can use liquid and two kinds of materials of solid simultaneously, each position uniform in shaping exhaust is unimpeded, and charging is young to be heated evenly, and has improved the stability of technology, simultaneously, because it is simple in structure, make mold design simple relatively, can omit vacuum extractor, the annex of global formation is because charging aperture is few in addition, overlap that is produced and tailing are also less, thereby have reduced cost.
Description of drawings
Fig. 1 is a mould schematic diagram of the present invention.
Among Fig. 1,1 vertical lateral port, 2 vertical mouths, 3 transverse holes, 4 transverse holes, 5 bed dies, 6 molds, 7 steam vents, 8 core rods, 9 semiconductive elements, 10 HV cable accessories.
Embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.
In Fig. 1, the forming method that this HV cable accessories 10 insulated parts are made, what use is the mode of matched moulds up and down, this mould, form by mold 6, bed die 5 and core rod 8, the inside groove shape is the shape of HV cable accessories 10 insulated parts, and there is one group of vertically mouth 2 the close end of mold 6, and a plurality of steam vents 7 are arranged on the surface longitudinal axle of mold 6; One group of corresponding vertically transverse holes 4 of mouth 2 is arranged on the bed die 5, and transverse holes 4 communicates with die cavity, the vertical lateral port 1 that also has one group of transverse holes 3 and communicate with it on the bed die 5, and transverse holes 3 communicates with die cavity.
With fluent material both liquid silastic is example, the concrete operations step is: at first prefabricated profiled semiconductive element 9 is installed on the core rod 8, apply enough temperature, time and pressure, the silicon rubber of flowability is injected in the die cavitys from the vertical mouth 1 and the transverse holes 3 of bed die, make it to be full of whole die cavity, build-up pressure; From a plurality of steam vents 7 overflow exhausts of bed die transverse holes 4 and mold, when sizing material was full of die cavity, pressure transmitted from inside to outside, semiconductive element 9 bears equal substantially pressure, can make with the position of insulating evenly, and exhaust is unimpeded, and charging is young, and under certain temperature and pressure, sizing material is subjected to smoothing out with the fingers and turns usefulness into, be heated evenly, the big stability that improves technology, simultaneously, because simple in structure, make mold design simple relatively, can omit vacuum extractor.
During annex moulding that usually overall dimension is bigger, generally need sectional forming, sometimes need ability moulding more than three times, and the present invention can be used for the bigger annex moulding of overall dimension, belong to integral one-step molding technique, owing to be whole material feeding, the die cavity internal pressure is always transmitted from inside to outside, can solve the excessive and defective of easy-formation not of product size, this method is applicable to the insulating material of solid and liquid.The annex of global formation is because charging aperture is few in addition, and overlap that is produced and tailing are also less, thereby have reduced cost.
