Abstract
The invention discloses an extrusion mold of a bicolor plastic steel core coextrusion cold upsetting curtain rod. The extrusion mold comprises a mouth mold 1, a left pressure plate, a mouth mold 2, a tubular core bar, a mold body, a right pressure plate and a long screw. The extrusion mold is characterized in that a mouth mold hole is formed in the middle of the mouth mold 1; a plurality of circular arc grooves evenly distributed in the peripheral direction are formed in the mouth mold hole; a color composite material feed port is formed below the mouth mold 2; a base material feed port is formed above the mold body; the mouth mold 1 is axially pressed by the left pressure plate, and is peripherally pressed through a mouth mold screw; the right pressure plate is connected with the mold body by adopting a pressure plate screw; a boss at the right side of the tubular core bar is pressed in a hole of the mold body by the right pressure plate; and the left pressure plate, the mouth mold 2 and the mold body are connected in sequence by the long screw. The curtain rod, processed by the extrusion mold, has the advantages of beautiful surface, high rigidity, high strength, few consumed materials, low cost and long service life.
Description
Technical field
The present invention relates to mould, particularly the cold roof window curtain rod of a kind of dual-color plastic steel core co-extrusion extrusion die.
Background technology
Existingly for hanging up the curtain rod of curtain, mostly adopt smooth solid wood rod or round steel pipe to make, adopt the structure of solid wood rod can consume a large amount of timber, waste resource, and the surface processing of need spraying paint, cost is high, and adopt the structure of common round steel pipe for antirust, also the processing of need spraying paint on the surface of round steel pipe, cost is high, also has and adopts stainless steel tube as the mode of curtain rod, although this mode surface aesthetic and antirust, cost is higher.
Summary of the invention
Object of the present invention is just to provide that a kind of curtain rod surface aesthetic, rigidity processing is large, intensity is high, consumptive material is few, cost is low, the cold roof window curtain rod of the dual-color plastic steel core co-extrusion extrusion die of long service life.
For achieving the above object, the present invention includes mouthful mould one, left pressing plate, mouth mould two, tubulose plug, die body, right pressing plate and long spiro nail, the centre of described mouthful of mould one is provided with a mouthful nib, in described mouthful of nib, be provided with several circumferentially uniform arc grooves, the below of described mouthful of mould two is provided with colored compound material charging aperture, the top of described die body is provided with base-material charging aperture, described mouthful of mould one adopts left pressing plate to carry out axial compression, and circumferentially compress by mouth mould screw counterpart mould one, described right pressing plate adopts bridge screw to be connected with die body, described tubulose plug adopts right pressing plate that the boss on tubulose plug the right is pressed in the hole of die body, described long spiro nail is successively by left pressing plate, mouth mould two and die body connect.
The present invention is because the centre at mouth mould one is provided with a mouthful nib, and in mouth nib, be provided with several circumferentially uniform arc grooves, can process by expressing technique the curtain rod of surface band circle-arc tooth, the base-material charging aperture of being located at die body top can be at steel tube surface coextrusion plastic layer, and be located at the colored compound material charging aperture of mouthful mould two belows, can be at the desired location on plastic layer surface compoundly go out colored plastic layer.The curtain rod surface aesthetic that the present invention processes, rigidity is large, and intensity is high, and consumptive material is few, and cost is low, long service life.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is that enlarged drawing is looked on a left side of the present invention.
The specific embodiment
Referring to Fig. 1 to Fig. 2, the present invention includes mouthful mould 1, left pressing plate 2, mouth mould 24, tubulose plug 5, die body 6, right pressing plate 7 and long spiro nail 8, the centre of described mouthful of mould 1 is provided with mouthful nib 11, in described mouthful of nib 11, be provided with several circumferentially uniform arc grooves 111, the below of described mouthful of mould 24 is provided with colored compound material charging aperture 41, the top of described die body 6 is provided with base-material charging aperture 61, described mouthful of mould 1 adopts left pressing plate 2 to carry out axial compression, and circumferentially compress by mouth mould screw 3 counterpart moulds 1, described right pressing plate 7 adopts bridge screw 9 to be connected with die body 6, described tubulose plug 5 adopts right pressing plate 7 that the boss on tubulose plug 5 the right is pressed in the hole of die body 6, described long spiro nail 8 is successively by left pressing plate 2, mouth mould 24 and die body 6 connect.
During practical application, steel pipe is entered and is passed always the hole of tubulose plug 5 centres from the Kong Zhongleng tip cuttings of right pressing plate 7 centres, then, base-material enters from base-material charging aperture 61, can be at the surperficial coextrusion plastic layer of steel pipe, meanwhile, colored compound material enters from colored compound material charging aperture 41, can be at the desired location on plastic layer surface compoundly go out colored plastic layer, thereby process curtain rod.
