Abstract
The invention discloses a plastic extruder with double charging barrels. The plastic extruder comprises a base and two extruder bodies, wherein two ends of the base are respectively provided with a fixed seat; each fixed seat is connected with a supporting column; the upper ends of the supporting columns are provided with the left and right charging barrels; a push rod is arranged inside each charging barrel; the upper end of each push rod is connected with a hydraulic oil cylinder through a main shaft of the hydraulic oil cylinder; the top end of each charging barrel is simultaneously provided with a charging hopper; and a charging hole is formed in each charging hopper. The charging operation can be simultaneously carried out at left and right sides of the plastic extruder with double charging barrels, so that the work efficiency is greatly increased; and meanwhile, the thickness of a product prepared by using the plastic extruder is uniform, and the quality of a finished product is high.
Description
Technical field
The present invention relates to Mould Machining machinery field, particularly relate to a kind of double cartridge plastic extruder.
Background technology
In mould of plastics processing industry, plastics are on the low side, and humidity, imputrescibility, lightweight, non-corrosive, so plastic applications is more and more wider, along with the popularization of plastics, plastic extruder application also gets more and more, extruder is extruded by the extrusion of molten plastic by solid shape under screw acting, through supercooling under hauling machine effect, and cutting after sizing. the different cross section products such as pipe, rod, profile shapes can be produced.
Existing extruder, as the capital equipment of extruding plastic forming production line, there is ineffective defect, such as plastic sole, use as sandals, the substantial amounts needed, traditional extruder single shaft or Double shaft stirring and extrude, efficiency is low, can not meet the large batch of demand in market, and existing extruder is owing to carrying out matched moulds and die sinking for a long time, extruder uses frequent, easy generation mechanical wear, and cause die life of being mated to decline, goods are the phenomenon such as jagged easily.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of double cartridge plastic extruder, greatly can improve the operating efficiency of plastic extruder.
Described a kind of double cartridge plastic extruder, comprise base and two extruder bodies, described base is the support section of double cartridge plastic extruder, in order to better stablize plastic extruder, described base is provided with damping device.
Described base is rectangular structure form, holder is respectively arranged with at base two ends, described holder adopts square block structure, holder is connected to support column, described support column upper end is two, left and right barrel, described barrel adopts quality steel plate to be welded, compact conformation, extrusion pressure is large, vacuum is high, sturdy and durable, push rod is provided with in barrel inside, push rod upper end is connected with hydraulic jack by hydraulic jack main shaft, described hydraulic jack is provided with up oil filler point and descending oil filler point, hydraulic jack extrudes power for extruder provides.
A kind of optimal technical scheme, described hydraulic jack can replace with electric machine, and motor extrudes power by the acting in conjunction of gear reduction box for extruder provides.
Be provided with reinforced hopper on the top of barrel, reinforced hopper is provided with charge door, and simultaneously in order to reinforced convenience, in reinforced hopper, be provided with puddler, material does not stop stirring through puddler and enters extruder body simultaneously.
Barrel lower end is provided with heater near exit, material is heated, make it be converted to fused materials, under hydraulic jack thrust, produce the pressure to fused materials, fused materials is extruded by cavity charging aperture in extruder body, the present invention adopts two extruder bodies, and mass flow is large, thus improves operating efficiency, material enters in mould molding cavity through collecting, thus extruded.
In mould molding cavity, be provided with mold closing mechanism and die-sinking device, when after material cooling forming, eject through ejection system, thus complete the manufacturing process of goods.
