Description
Technical field
The present invention relates to the plastic hollow vessel extrusion blow molding machine, be used to make massive article such as oil drum, highway barrier etc., small-sized goods such as mineral water bottle, beverage bottle, medicine bottle, bottle for cosmetics etc. belong to plastics machinery and make the field.
Background technology
The plastic hollow extrusion blow molding machine is the capital equipment of hollow container moulding, by extruder molten plastic is clamp-oned die head earlier, through die head extruded stock pipe, the material pipe is between two slit bamboo or chopped wood die cavities of mould, and matched moulds, inflatable body inject air in material is managed, the goods blow molding, goods are taken out in die sinking.But existing extruding and blowing machine exists following defective: the first, and for massive article, goods more than Φ＞500 millimeter particularly, it is far from being enough only depending on inflatable body to blow, the result can cause expanding not in place, difficult forming; Second, die head is according to the goods of different geometries, make the wall thickness at each position of extruded stock pipe not of uniform size, be that some position material needs more, and some position material needs few, could blow out the uniform goods of wall thickness like this, making massive article (as oil drum, highway barrier etc.) time, the general accumulator coventry type die head coventry that adopts, but the core of existing accumulator coventry type die head coventry is constant with the fixed-site of mouthful mould, so can not regulate the axial wall thickness of material pipe, very easily causing in the blowing process causes the wall unevenness of end article even because of the wall thickness of material pipe is inharmonious, even produce and to break, goods are scrapped many, and shaping efficiency is low; The 3rd, the clasp mould mechanism that has extruding and blowing machine is general to adopt 4 pull bars to connect front template, middle template and rear pattern plates, and promptly four of each template angles all have pull bar keeping off, all inconvenient when installation mold and taking-up goods, and die cylinder is template in linkage drives, complex structure; The 4th, the manipulator that existing extruding and blowing machine is used to take out goods adopts the guide pillar guiding, guidance quality and wearing no resistance, and since manipulator about do not have lazy-tongs between two tongs, action is difficult to reach synchronous, consistent, causes grasping unstable.
Summary of the invention
The objective of the invention is provides a kind of inflatable body of can assisting to finish the blowing process jointly in order to overcome the shortcoming that prior art exists, and massive article (the particularly goods more than Φ＞500 millimeter) expansion is put in place, and moulding is complete; Can regulate the wall thickness size of extruded stock pipe, the wall thickness size at each position of extruded stock pipe be coordinated with end article, thereby made the product wall thickness that is blow molded into even, improve product strength and shaping efficiency; Side between front template and the middle template is with very big space outward, is convenient to installation mold and takes out bigger goods; Manipulator guidance quality and wearability are good, and two tong actions make and grasp stable plastic hollow vessel extruding and blowing machine fully synchronously.
The technical scheme of plastic hollow vessel extruding and blowing machine of the present invention is: comprise rack-mounted plasticizing system, die head extrusion system and blow-molding system, described die head extrusion system comprises that rack-mounted die head supports, die head support fixation die head, die head comprises die head loam cake and die body, be shaped on storage cavity in the die body, the die head loam cake is communicated with barrel and storage cavity through the joint neck, and the ring that shoots material is housed in the storage cavity, and the ring that shoots material connects the piston rod of the oil cylinder that shoots material through the pillar that shoots material; Die body lower end connector mould; mouth mould central authorities are provided with core; gap between core and mouthful mould forms the extrusion of annular; described blow-molding system comprises inflatable body and clasp mould mechanism; clasp mould mechanism comprises front template; middle template and rear pattern plate; front template is linked to each other by pull bar with rear pattern plate; between front template and the middle template mould is housed; mould comprises two slit bamboo or chopped wood die cavities of symmetry; between middle template and the rear pattern plate folding mould lazy-tongs are housed; middle template is driven by die cylinder; it is characterized in that described two slit bamboo or chopped wood die cavity inwalls are shaped on support material bar groove respectively; firm banking under the mould; be connected and fixed plate through the up-down adjustment device on the base; hoist cylinder is installed on the fixed head; the piston rod of hoist cylinder connects transverse slat; on the transverse slat through left and right sides riser fixing horizontal guide pillar; left and right sides riser is installed expansion oil cylinder first and expansion oil cylinder second respectively; the direction of motion of two expansion oil cylinder piston bars is opposite; the two-piston bar is respectively through connecting plate rigid staybolt material piece; on the two support material pieces support material bar is installed respectively; support material bar matches with support material bar groove respectively; two support material pieces are enclosed within respectively on the horizontal guide pillar; the blow needle fixed block is housed in the middle of the horizontal guide pillar; on the blow needle fixed block blow needle is installed, blow needle matches with the gas hole of mold bottom.
Plastic hollow vessel extruding and blowing machine of the present invention is set up expanding mechanism on the basis of existing inflatable body, will expect that earlier the pipe bottom struts, and blows, thereby the material enlargement of pipe is put in place, is easy to moulding, is specially adapted to diameter greater than the goods more than 500 millimeters; Horizontal guide pillar has been arranged; make support material piece first; second operates steadily; its concrete course of work is as follows: system obtains molten plastic from plasticizing; molten plastic is through die head extruded stock pipe (the material pipe is the open circles tubulose); reach the length (promptly support material bar is positioned at the material pipe) of setting when the material pipe after; the closed material that cuts off automatically of mouth mould is managed; expansion oil cylinder first; second starts; drive connecting plate respectively through separately piston rod; support material piece and support material bar move dorsad (promptly to two movement outside); support material bar will expect that the support of pipe bottom is big; till piston rod all stretches out; at this moment; clasp mould mechanism makes the mould matched moulds; matched moulds back brace material bar just in time is positioned at the corresponding support material of die cavity bar groove; hoist cylinder drive transverse slat and all parts that are installed on the transverse slat move upward together; make blow needle insert the gas hole of mold bottom; in the material pipe, inject air by blow needle; behind the blow molding; clasp mould mechanism drives the template die sinking; hoist cylinder drive blow needle moves down and resets; take out goods (can adopt and manually get bottle, also can adopt manipulator to get bottle), the expansion oil cylinder drives support material bar and resets.
