Description
Technical field
The present invention relates to a kind of former, more particularly, to a kind of metering and device for cutting and be provided with the automatic on-line extrusion of this device, compression molding system.
Background technology
The processing and forming mode of composite material of thermoplastic macromolecule mainly has extrusion molding and injection mo(u)lding two kinds, and extrusion moulding product is the section bar that cross section is identical, and being injection molded into moulded products can for complex-shaped special-shaped product.For composite material of thermoplastic macromolecule, the thickness of injection moulded products directly affects molding cycle and product quality, and thus be accordingly used in the composite fluidity of injection mo(u)lding must get well.For the goods that breadth is bigger, certainly will selecting large-tonnage injection moulding machine according to injection mo(u)lding, equipment investment is high.
The thermoplastic composite poor fluidity that development in recent years is swift and violent, the injection mo(u)lding difficulty of special-shaped product is big, and quality of item is wayward, although this material can pass through the strip section of extrusion molding same cross-sectional, but range of application is extremely restricted, the processing for special-shaped product is helpless.
For the technique solving to utilize the poor thermoplastic composite of mobility to produce large format special-shaped product, composite product company of the U.S. (CPI) proposed LFT-D technology in 1989, and after 2003, rapidly be development, representative complete set of equipments manufacturing company includes W&P company of Germany, source, state inland sea machinery.Its material being suitable for is mainly glass fiber reinforced polypropylene (on a small quantity also with nylon) composite, and goods are mainly auto parts and components.The shortcoming of this technology is in that material narrow application range, have employed the principle of the conservation of mass in material metering process, and under the extruder of front end, raw material is adopted online dynamically weighing type feeding by feeding place, adopts timing cutting at extruder end.This metering method is high for the composite device customizing cost of complicated components, controls difficulty big.For special composite material, as height fills biomass composite, its viscosity is big, the feature of poor fluidity make its from double screw extruder extrude time instability, not easily in bulk, scatter being transferred to die cavity Nei Shiyi.
For utilizing injection mo(u)lding, price high and existing LFT-D extrusion-die pressing technique unfavorable problem huge with equipment difficult, die needed in thermoplastic composite (including semifluid shape bulk cargo) the molding large format special-shaped product process of poor fluidity, a kind of new automatic online extrusion-die pressing molding equipment of exploitation solves the problems referred to above and has very important significance.
Summary of the invention
The technical problem to be solved in the present invention provides one metering and device for cutting, and this device is mainly made up of piston, accumulator and corresponding drive system, and when the material injected in accumulator reaches certain capacity, the material in accumulator is extruded by piston in the lump.This device makes the material of poor fluidity will not be bonded in accumulator inwall, makes semifluid shape bulk cargo compacting aerofluxus, quantitative accurate, and formed precision is high.
The present invention also provides for a kind of full-automatic online extrusion, compression molding system, goods are realized seriality from material to the process of molding by this system, and use above-described metering and device for cutting, make quantitative accurate, control simple, the goods formed meet the requirement of design, and further by PLC controls, it is achieved the seriality of product molding process and increasingly automated.
