Abstract

The utility model relates to an ultra high molecular weight polyethylene tubing extrusion equipment comprising a material canister which is provided with a screw rod along the central line of the inner cavity of the material canister; one end of the material canister is provided with a hopper, another end of the material canister is provided with a front barrel flange which is connected with diversion node of mould; the diversion node is connected with the spreader shell through bolt; the spreader shell is provided with inner core whose front end and conical hole of diversion node inner cavityconstitutes a feeding passage; end of the spreader inner core is sequentially connected with several segments of mould through the bolt. In the utility model, the ultra high molecular weight polyethylene tubing extrusion equipment reduces side thrust and simultaneously reduces adhesive force between material and screw rod, in another aspect ensures the material can not rotate under strong back pressure and high speed rotation of screw rod while high pressure plasticizing is implemented.

Description

The ultrahigh molecular weight polyethylene tubing extrusion equipment
Technical field
The utility model relates to a kind of ultrahigh molecular weight polyethylene tubing extrusion equipment.
Background technology
At present, the domestic special equipment of producing ultrahigh molecular weight polyethylene tubing that still finds no, once the someone was gone on the market and is adopted the plunger extrusion molding to produce small-bore thin-walled ultrahigh molecular weight polyethylene tubing, but must not implement because of poor product quality; External existing like product, but, be not suitable for reason appearance as yet on China market such as China's needs owing to complex structure, manufacturing cost height.
The utility model content
The purpose of this utility model provides a kind of ultrahigh molecular weight polyethylene tubing extrusion equipment, to overcome the deficiency of problems such as existing ultrahigh molecular weight polyethylene tubing extrusion equipment complex structure, manufacturing cost height.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of ultrahigh molecular weight polyethylene tubing extrusion equipment, comprise barrel, have vertical straight trough on the described barrel madial wall, the barrel inner chamber is provided with screw rod along center line, one end of barrel is provided with hopper, the other end of barrel is provided with the machine barrel flange, machine barrel flange and inner chamber are that the mould water conservancy diversion joint of bellmouth is connected, mould water conservancy diversion joint connects the spreader shell by bolt, the spreader enclosure is provided with the spreader inner core, the front end of spreader inner core is the conehead shape, form feeding-passage between the bellmouth of front end and mould water conservancy diversion joint inner chamber, the end of spreader inner core connects some joint moulds successively by bolt, and wherein the die wall of terminal mould is provided with the adjusting bolt, the rear end of terminal dies cavity is provided with solid type briquetting, and the outside, terminal mould rear end is provided with cooling duct; The inner chamber of described mould is provided with and the corresponding inner core of mould, and forms the pipe fitting path that is extruded to shape between each inner core, and the path that is extruded to shape diminishes by joint between the terminal inner core from the spreader inner core.
The beneficial effects of the utility model are: one side has realized that the task of minimizing side-thrust has reduced the adhesive force between raw material and the screw rod simultaneously; Realized that on the other hand high pressure plastifies the performance that is shaped guarantees can not occur the raw material rotation simultaneously under back pressure and screw rod rotate at a high speed by force situation down.
