Abstract
The utility model discloses a high-density polyethylene water supply pipe external surface burnishing device which comprises an opening die, a steel sleeve, a plastic ring and four inner hexagon screws in uniform peripheral distribution; the steel sleeve is provided with four screw holes in uniform peripheral distribution; the left end surface of the steel sleeve is provided with a seam allowance; an inner hole of the steel sleeve is internally provided with an inner boss; the center of the steel sleeve is provided with a round hole; the right end surface of the opening die is provided with a groove and four thread holes in uniform peripheral distribution; the center of the opening die is provided with an open die hole; the plastic ring is installed in the inner hole of the steel sleeve; the right end surface of the plastic ring clings to the left end surface of the inner boss of the steel sleeve; the seam allowance of the steel sleeve is inserted into the groove of the opening die; and the steel sleeve is connected with the opening die through the four inner hexagon screws in uniform peripheral distribution. The high-density polyethylene water supply pipe external surface burnishing device provided by the utility model can improve the quality of the outer surface of a polyethylene water supply pipe obviously, can produce products with beautiful appearances, is simple in structure, and has long service life.
Description
Technical field
The utility model relates to mould of plastics, specifically high density polyethylene (HDPE) feed pipe outer surface extrusion processing device.
Background technology
What existing mould mouth mould for the production of the high density polyethylene (HDPE) feed pipe adopted is that mould steel is made, because its surface roughness is larger, and its skin-friction coefficient is larger, thus adopt the outer surface of the high density polyethylene (HDPE) feed pipe that this mouthful mould processes smooth not, and not attractive in appearance.
The utility model content
The purpose of this utility model just provides that a kind of product design that can significantly improve high density polyethylene (HDPE) feed pipe outer surface quality, process is attractive in appearance, simple in structure, the high density polyethylene (HDPE) feed pipe outer surface extrusion processing device of long service life.
For achieving the above object, the utility model comprises a mouthful mould, also comprise steel bushing, plastic hoop and four circumferential uniform soket head cap screws, described steel bushing is provided with four circumferential uniform screw holes, the left side of described steel bushing is provided with seam, be provided with inner convex platform in the endoporus of described steel bushing, the center of described steel bushing is provided with circular hole, the right side of described mouthful of mould is provided with groove and four circumferential uniform screwed holes, the center of described mouthful of mould is provided with a mouthful nib, described plastic hoop is loaded in the endoporus of steel bushing, the right side of described plastic hoop is adjacent to the left side of the inner convex platform of steel bushing, in the groove of the seam insert port mould of described steel bushing, described steel bushing is connected with a mouthful mould by four circumferential uniform soket head cap screws; Described plastic hoop adopts polytetrafluoroethylmaterial material to consist of; Adopt matched in clearance between the outer round surface of described plastic hoop and the endoporus of steel bushing; Adopt matched in clearance between the groove of the seam of described steel bushing and mouthful mould.
The utility model is owing to having adopted the plastic hoop of being made by polytetrafluoroethylene (PTFE) (being commonly called as " King ") material, polytetrafluoroethylene (PTFE) has not viscosity of little, the good corrosion resistance of coefficient of friction and surface, when plastic liquid passes through the inner surface of plastic hoop, can process to get gloss very with the surface of the contacted plastic liquid of plastic hoop inner surface, thereby so that high density polyethylene (HDPE) feed pipe outer surface becomes smooth bright.The utility model can significantly improve high density polyethylene (HDPE) feed pipe outer surface quality, and the product design that processes is attractive in appearance, and is simple in structure, long service life.
