Abstract
A shaping die for manufacturing a high voltage cable accessory insulating part is composed of an upper die (6), a lower die (5) and a die core (8), wherein the shape of a die cavity is the shape of a high voltage cable accessory insulating part. The shaping die is characterized in that the upper die (6) is provided with a group of longitude ports (2) close to the end portion, a longitude shaft on the surface of the upper die (6) is provided with a plurality of exhaust holes (7), the lower die (5) is provided with a group of transverse holes (4) corresponding to the longitude ports (2), the transverse holes (4) are communicated with the die cavity, the lower die (5) is further provided with a group of transverse holes (3) and longitude ports (1) communicated with the transverse holes (3), and the transverse holes (3) are communicated with the die cavity. The high voltage cable accessory insulating part can be wholly shaped in one time, a set of dies can use two materials of liquid and solid simultaneously, the shaping of each part is even, the exhaustion is smooth, a material inlet is small and is heated evenly, the technique stability is improved, furthermore, and accessories which are integrally shaped generate less flash and leftover bits and pieces of industrial material since the material inlets are few, thereby lowering the cost.
Description
Technical field
The utility model belongs to HV cable accessories and makes the field, relates in particular to be used for the mould that the HV cable accessories insulated part is made.
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 purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of mould that the HV cable accessories insulated part is made that is used for is provided.
The technical solution of the utility model is, a kind of mould that is used for the manufacturing of HV cable accessories insulated part, 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 utility model, 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 utility model.
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
Below in conjunction with accompanying drawing the utility model is described in further detail.
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.
Claims (1)
1. one kind is used for the mould that the HV cable accessories insulated part is made, form by mold (6), bed die (5) and core rod (8), the die cavity shape is the shape of HV cable accessories insulated part, it is characterized in that: the close end of mold (6) has one group vertically mouthful (2), 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 mouthful (2) is arranged on the bed die (5), and transverse holes (4) communicates with die cavity, and bed die (5) is gone up vertical mouthful (1) that also has one group of transverse holes (3) and communicate with it, and transverse holes (3) communicates with die cavity.
