Abstract
The utility model discloses a plastic pipe shaping extrusion device, which comprises an extrusion die and a sizing sleeve, wherein the extrusion die comprises a mouth die and a core die, and the external diameter of the outlet of the mouth die of the extrusion die is smaller than the internal diameter of the sizing sleeve; an air flow channel is arranged in the core die, and the air inlet of the air flow channel is communicated with an air source; and the air outlet of the air flow channel is positioned on the core die at the outlet end of the mouth die of the extrusion die. The utility model has the advantages that: the pipe bears the radial force and the axial force simultaneously when going out of the mouth die, so that the pipe deforms along the axial and radial directions simultaneously, and the grains of pipe plastic after cooling crystallization are changed into a gravel shape from a strip shape, thereby greatly improving the compressive strength and tensile strength of the pipe.
Description
Technical field
The utility model relates to a kind of plastic pipe modular system, particularly a kind of plastic pipe typing extrusion device.
Background technology
Extrude in the production at various plastic pipe Vacuum shapings,, often the mouth mould external diameter of extrusion die is processed into and is slightly larger than the calibration sleeve internal diameter, extrude the stability of production with raising for favourable vacuum seal.And the mouth mould external diameter of extrusion die during greater than the calibration sleeve internal diameter, when pipe enters calibration sleeve by extrusion die, is just had an inwardly process of extruding, thereby reduced the mechanical performance of the tubing of producing.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of good vacuum seal that can realize is provided, and can guarantee that again the mechanical performance of the tubing of producing is impregnable, also can improve production stability plastic pipe typing extrusion device.
A kind of plastic pipe typing extrusion device, comprise extrusion die and calibration sleeve, extrusion die comprises mouthful mould and core, its structural feature is: the mouth mould outlet external diameter of extrusion die is less than the internal diameter of calibration sleeve, in core, be provided with air flow passage, the air inlet and the source of the gas of described air flow passage are conducted, and the gas outlet of described air flow passage is positioned on the core of the extrusion die mouth mould port of export.
The plastic pipe typing extrusion device of this structure, when work, can make tubing when the outlet mould, be subjected to the effect of radial load and axial force simultaneously, pipe is axially being deformed simultaneously with both direction radially, make the grain shape of tubing plastic cool crystallization transfer the gravel shape to, thereby improve the compressive resistance and the hot strength of tubing greatly, the experiment proved that by strip, the hydraulic pressure strength of tubing is high more about about 20% than common process, and the stability of production is also improved greatly.
Described core is a kind of hollow core, and the inner chamber of core constitutes air flow passage.
Described gas outlet or be one or for a plurality of, a plurality of gas outlets is positioned at the same cross-section of core.
The outlet external diameter of described extrusion die mouth mould is littler by 30%～50% than the internal diameter of calibration sleeve.
In sum, advantage of the present utility model is:
Plastic pipe typing extrusion device of the present utility model, can make tubing when the outlet mould, be subjected to the effect of radial load and axial force simultaneously, thereby make its axially with radially deform simultaneously, make the grain shape of tubing plastic cool crystallization transfer the gravel shape to by strip, thereby improve the compressive resistance and the hot strength of tubing greatly, the experiment proved that the hydraulic pressure strength of tubing is high more about about 20% than common process, the stability of Sheng Chaning also improves greatly simultaneously.
