Description
Technical field:
The present invention relates to a kind of thick article that is particularly suitable for, block bar etc. as filter press filter board, engineering plastics slab, plastic building template, plastics track for a train sleeper, plastic inspection well lid, plastics, also be applicable to thin-gage goods, as equipment and the technology that auto parts machinery, small-sized pleasure-boat body, plastics pump case, plastic pipe, logistics goods etc. are made, belong to plastics extrusion molding equipment and expressing technique and make the field.
Background technology:
Along with the development of technology and the extensive use of engineering plastics, large-scale, super-huge plastic products more and more appear at people production, the life in, this former, mould that just requires plastics is to large-scale, super-hugeization development, naturally, the manufacturing technology requirement of equipment, precision etc. are also more and more higher, requirement meeting to working ability, scope and the material of equipment is harsher, and thing followed problem is the equipment manufacturing cost costliness, and the investment payback time is long.
Summary of the invention:
Purpose of design: it is big and by the low cost former and the technology of digital control system control plastics extrusion molding to design a kind of low pressure, capacity.
Design: in order to realize above-mentioned purpose of design.The application divides four major parts in the design of equipment: plasticized screw, storing are extruded cylinder, vertical clamping, numerical control system.1 plasticized screw: the even action ground heating plasticizing that engineering plastics (can virgin material, part returns, full returns) is subjected to the heater in the screw portion; And the screw rod in the plasticized screw is on structural design, and screw rod can single screw-rod structure, also can be double-screw structure.Twin-screw can be directly that engineering plastics are carried out glass etc. is fiber-reinforced modified, reduce Master Cost.2, storing is extruded cylinder: storing is extruded cylinder in design, being installed in can be on the track that X, the numerical control of Y horizontal direction are moved, purpose is to be convenient to storing extrude material in the cylinder and can make things convenient for and be injected in the mold cavity equably, the external charged heat tracing layer of material storage tube can guarantee that the material in the storing cylindrical shell is in molten condition all the time.The melting charge that spiro rod plasticizing is good is pushed into accumulator, and accumulator piston (referring to extrude oil cylinder piston) retreats thereupon, up to desired volume (detecting capacity automatically by the position chi), cuts off valve between screw rod and accumulator.3, vertical clamping: the vertical clamping of four-column type or frame-type, the Tape movement workbench is convenient to mould and is installed.Open mould, storing is extruded cylinder nozzle shift-in counterdie top, extrudes cylinder X, Y direction position by the control storing, and the piston of oil cylinder promotion simultaneously moves ahead, and melting charge is extruded into each position of mould on request.Withdraw from storing and extrude cylinder, the shut-off nozzle valve enters the next storing cycle.Clamping begins matched moulds, pressurize, up to technological requirement, and die sinking, manipulator stretches into die cavity, catches to eject goods, and manipulator shifts out, and goods are delivered to assigned address.Enter next circulation.4, numerical control system: detection that control system comprises entire equipment and operation control contain that the temperature control of PID material, screw rod cold start protection, hopper lack that material is reported to the police, the control of multistage folding mould speed, operating trouble are reported to the police, the warning of oil temperature, pressure and temp position probing etc.
Technical scheme 1: the large-capacity digital-controlled squeeze note plastics forming of low pressure equipment; it comprises vertical clamping; storing is extruded cylinder (9) and is installed in the track (14 that can move in X, the numerical control of Y horizontal direction; 13) on; plasticized screw (8) is positioned at storing to be extruded cylinder (9) and goes up and extrude cylinder (9) by valve (7) and storing and is communicated with, and data control system is used for controlling the control that storing is extruded cylinder (9) material temperature and expected multistage folding mould speed in scarce warning, the middle screw rod cold start protection of plasticized screw (8), the vertical clamping.
Technical scheme 2: the large-capacity digital-controlled squeeze note plastic forming technology of low pressure; plastics enter screw rod from hopper; after the plasticized screw plasticizing, enter accumulator by valve by the screw rod rotation; after storing is finished; the nozzle valve that storing is extruded in the cylinder moves on to the die cavity top that is arranged in vertical clamping counterdie; oil cylinder promotes its piston and quantitatively clamp-ons in the die cavity according to numerical control system instruction through nozzle valve the storing in the accumulator; withdraw from storing then and extrude cylinder; upper and lower mould matched moulds pressurize in the vertical clamping; enter storing of following one-period simultaneously; die sinking after pressurize is finished, manipulator enter die cavity and take out goods.
The present invention compares with background technology, the one, vertical clamping, simple in structure, to take up an area of the space little, its travelling table is convenient to mould and is installed, and makes things convenient for massive article to take out; The 2nd, the mould open type feeds intake, and extrusion pressure significantly reduces, and can reduce cylinder diameter; The 3rd, movable numerically-controlled feeding intake, rate of feeding, quantity can help thick article and be shaped by the control of goods diverse location, can accomplish pore-free, simultaneously, significantly reduce clamping pressure, are about 50% of the common injection machine of same article projected area; The 4th, storing is extruded the application of cylinder, significantly reduces the diameter and the length of plasticized screw, and it is easier to process.Be equipped with two storings and extrude cylinder, can realize uninterrupted plasticizing, significantly enhance productivity by valve control; The 5th, storing is extruded the cylinder nozzle and is not fixedlyed connected with mould, and mould can be cancelled TOP-TIP, reduces die manufacturing cost and cycle greatly; The 6th, storing is extruded the application of cylinder, can change the capacity of extruding easily, is convenient to the replacing of product; The 7th, plasticized screw, storing are extruded cylinder can widely apply waste or used plastics, can significantly reduce the production of articles cost, reduces environmental pollution simultaneously; The 8th, total installed capacity power is low, is about below 50% of common injection machine; The 9th, modularized design is convenient to by goods requirement adjustment combination, and the equipment total cost is about below 50% of common injection machine, and its product strength obviously improves, and has eliminated manually to feed intake or cold shut, pore, exhaust that common injection machine is shaped such as burn at problem.
