Abstract
The utility model discloses an improve mould of wisdom energy locomotive cable degree of eccentricity, including extrusion formula mold core, positioning bolt, die sleeve and positioning die, positioning die is hollow structure, including mold core locating surface, die sleeve locating surface and round pin, the front end inclined plane of positioning die's internal surface is as the mold core locating surface, and positioning die's surface is as the die sleeve locating surface, the round pin runs through positioning die, the interior cone angle of mold core locating surface is 45 with the cone angle of extrusion formula mold core. The utility model discloses a mould that improves the locomotive cable degree of eccentricity can become a horizontal line with extrudeing the central fixed of formula mold core and die sleeve, can guarantee that insulation and sheath have high concentricity, after extrusion formula mold core and die sleeve are fixed takes positioning die out, does not completely influence the flow of material, therefore the effectual degree of eccentricity and the external diameter that has reduced the cable.
Description
Technical field
The utility model relates to locomotive cable field, refers in particular to a kind of mould improving the locomotive cable degree of eccentricity.
Background technology
The develop rapidly of China in Recent Years locomotive technology, locomotive electric cad system equipment is more and more accurate, thus stube cable quantity needed for intra-locomotive gets more and more, but intra-locomotive limited space, therefore the external diameter of cable requires more and more stricter.Locomotive cable insulation used and sheath material are low-smoke non-halogen flame-retardant oil resisting material, the mobility of this material is lower, adopt tubular molding tool production can cause insulation and jacket surface crude, insulation and sheath directly affect the electrical property of cable with conductor in conjunction with defective tightness simultaneously, therefore plsitive mold must be adopted to produce, but plsitive mold eccentric difficulty is comparatively large, eccentric process can waste a large amount of time and materials, can cause that the outside diameter of cable is bigger than normal cannot meet customer need simultaneously.
Cable adopts plsitive mold to produce insulation or sheath, to need express material by very large pressure to conductor, insulated wire cores or become on cable core, then be insulation or the sheath that line segment is squeezed into rounding by die sleeve, gained cable smooth in appearance rounding, insulation and sheath are combined with internal layer closely, excellent electrical property, therefore receives an acclaim.But eccentric is very difficult during operation, cause primarily of following factor: 1, plsitive mold extruding force is 2 ~ 3 times of crowded tubular type, core rod and die sleeve directly have the distance of about 4mm, just started to add man-hour Flow of Goods and Materials unstable, when die sleeve be line segment bear very large pressure be very easy to bias; 2, gap is had between core after multicore cable stranding and an inadequate rounding, therefore the aperture 0.2mm larger than the external diameter after stranding of squash type core rod is selected, this will cause into the mobile space that cable core has 0.2mm in core rod, during eccentric, the traction of core is unstable, thus causes the bias mixed up also to have bias after bursting at the seams.Therefore need to burst at the seams while eccentric, until till qualified, so repeatedly adjust test and can cause a large amount of wastes.Both added labour intensity, and can waste a large amount of materials again, general start eccentric can waste more than 10 meter of cable.The cable eccentricity degree produced in this way is generally more than 10%.
Chinese patent ZL200820040105.X disclosed " pressing type mold for electric cable protection sleeve ", the concentric sizing having radial direction to be greater than this cross section core rod external diameter in die core front end supports, and ensures in cable extrusion formula production process not eccentric.But because locomotive cable insulation and sheath material require halogen-free low-voltage oil resistant high flame retardant, the mobility of material is poor, and the program adds concentric sizing and supports on original mould, have impact on the flowing of material between core rod and die sleeve, causes material matched moulds region crude.Locomotive cable specification is more simultaneously, will increase a large amount of moulds, also can cause the waste of increasing in program implementation process.
Utility model content
The purpose of this utility model is to provide a kind of mould improving wisdom energy locomotive cable eccentricity degree.
The technical scheme realizing the utility model object is a kind of mould improving wisdom energy locomotive cable eccentricity degree, comprises squash type core rod, bolt, die sleeve and jig; Described jig is hollow structure, comprises core rod locating surface, die sleeve locating surface and pin; The inclined-plane, front end of the inner surface of described jig is as core rod locating surface, and the outer surface of jig is as die sleeve locating surface, and described pin runs through jig; The interior cone angle of described core rod locating surface and the cone angle of squash type core rod are 45 °.
Described bolt comprises fixes the upper bolt of die sleeve, lower bolt, left bolt and right bolt from four direction.
The minimum place internal diameter of described squash type core rod is 8.0mm, and the external diameter of jig is 11.9mm, and the internal diameter of die sleeve is 12.0mm.
Described pin to be inserted in jig and to be welded to connect with jig, and the height exposing die sleeve locating surface is 20mm.
Adopt technique scheme, the utility model patent has following beneficial outcomes:
(1) center of squash type core rod and die sleeve can fixedly be become a horizontal line by the mould of the raising locomotive cable degree of eccentricity of the present utility model, can ensure that insulation and sheath have high concentricity, jig is extracted out after fixing by squash type core rod and die sleeve, do not affect the flowing of material completely, therefore effectively reduce the degree of eccentricity and the external diameter of cable.
(2) jig of the present utility model is separated with die sleeve with squash type core rod, therefore traditional squash type core rod and die sleeve all can normally use, only need additional processing jig, this jig is identical with the cone angle of squash type core rod with die sleeve internal diameter, the aperture of squash type core rod can increase or reduce, therefore jig may be used for the production of multiple specification cable, very convenient and practical.
