Abstract
The utility model discloses a sound-muffling plastic pipe extrusion die, comprising a die body (1), a supporting plate II (2), a supporting plate I (3), a converging plate (4), a die II (5), a die I (6), a short screw (7) and a long screw (8). The sound-muffling plastic pipe extrusion die is characterized in that a circular die hole (61) is formed in the middle of the die I (6), a round mandril (9) and five circumferentially-distributed fan-shaped mandrils (10) are arranged in the circular die hole (61), the five circumferentially-distributed fan-shaped mandrils (10) are arranged on the supporting plate I (3) in a foot-embedding manner, the round mandril (9) is arranged on the supporting plate II (2) in a foot embedding manner, the die I (6) is connected with the die II (5) via the short screw (7), and the long screw (8) can be used for connecting the die II (5), the converging plate (4), the supporting plate I (3), the supporting plate II (2) and the die body (1) in sequence. The sound-muffling plastic pipe manufactured by adopting the die disclosed by the utility model is high in strength, great in stiffness, good in sound muffling effect, and long in service life.
Description
Technical field
The utility model relates to mould, particularly a kind of noise reduction plastic tube extrusion die.
Background technology
The existing hush pipe that adopts such as the occasion of the need noise reductions such as ship ventilation pipe is the common round plastic tube that adopts the Intermediate Gray circular hole mostly, although this hush pipe cost is low, intensity is low, cracky, and also erasure effect is relatively poor.
The utility model content
The purpose of this utility model just is to provide that a kind of noise reduction plastic tube intensity that processes is high, rigidity is large, erasure effect is good, the noise reduction plastic tube extrusion die of long service life.
for achieving the above object, the utility model comprises die body, supporting plate two, supporting plate one, cylinder manifold, mouth mould two, mouth mould one, short screw and long spiro nail, the centre of described mouthful of mould one is provided with the circular port nib, round plug and five circumferential uniform fan-shaped plugs are housed in described circular port nib, described five circumferential uniform fan-shaped plugs all adopt the edge pin to be loaded on supporting plate one, described round plug adopts the edge pin to be loaded on supporting plate two, described mouthful of mould one use short screw is connected with a mouthful mould two, described long spiro nail is successively with mouth mould two, cylinder manifold, supporting plate one, supporting plate two and die body connect.
The utility model is because the centre at mouth mould one is provided with the circular port nib, and round plug and five circumferential uniform fan-shaped plugs are housed in the circular port nib, like this, form one for the die cavity of extruding between circular port nib and circle plug and five circumferential uniform fan-shaped plugs, by coextrusion process, just can process the noise reduction plastic tube of Intermediate Gray circular hole and five circumferential uniform scallop holes.The noise reduction plastic tube intensity that the utility model processes is high, and rigidity is large, and erasure effect is good, long service life.
