Description
Technical field
The present invention relates to a kind of manufacturing process and product, particularly a kind ofly combine to penetrate principle and make plastic product such as filter, the invention still further relates to a kind of device that penetrates principle manufacturing plastic product that utilizes with the technology of filter vat.
Background technology
Tradition utilizes injection machine to make the mode of plastic product, all is by the uninterrupted plastics that spue that mix of screw in injection molding machine, again with extruded in plastic to mould; The production of injection machine is Guan Mo, injection molding, cooling; Die sinking, pushing-off product closes mould again ... this one-period repeatedly; Each action all is intermittent, owing to limited by the discharge-amount of screw rod, some needs the article of excess weight or complex structure; Then simple is the article that can't manufacture out integrated excess weight or complex structure with injection machine, thus need earlier with the parts of excess weight or complex structure article respectively injection moulding come out, then together with each component-assembled; So just will certainly increase the expense of die sinking, make equipment investment too huge and fail to reach needed finished weight.
Summary of the invention
In order to overcome the deficiency of prior art, an object of the present invention is to provide a kind of and combine to penetrate principle and make plastic product such as filter technology, but adopt this technology injection moulding to manufacture out the article of integrated excess weight or complex structure with filter vat.
Another object of the present invention is to provide a kind of the utilization to penetrate the device that principle is made the plastic article of integrated excess weight or complex structure.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of technology that combines to penetrate principle manufacturing plastic product; It is characterized in that the process using extruder and the mould of this manufacturing plastic product, described extruder is provided with feeding-passage, is provided with an extrusion storage vat and at least one deposit storage vat along feeding-passage; In extrusion storage vat and the deposit storage vat oil gear is installed; Between extrusion storage vat and the deposit storage vat control valve is installed, on the said extrusion storage vat discharge nozzle that docks with mould is installed, discharge nozzle is equipped with valve; Said mould is by the male model core, be installed in master mold on the male model core, be installed in the male model plate of master mold one end, master mold header board and the rear pattern plate that is installed in the master mold other end constitutes, and rear pattern plate is provided with the import that supplies discharge nozzle to insert; Said male model core is provided with the auxiliary demoulding hole of male model air, and rear pattern plate is provided with the auxiliary demoulding hole of rear pattern plate air; Be provided with the cooling duct in said male model core, master mold and the rear pattern plate; Said valve is a non-return valve; The technology of this manufacturing plastic product comprises the steps: that (1), dress mould will fit together by the mold component that the product design requirement is processed earlier; (2), storing opens the control valve of extruder, extrusion storage vat oil gear withdraws from, and molten plastic is given as security to the extrusion storage vat, and reached setting weight; Again control valve is closed, withdraw from deposit storage vat oil gear, let the plastics of the uninterrupted extrusion of extruder, be stored in the deposit storage vat; (3), butt joint is docked mould, and is utilized thread locking mould with extruder; (4), give as security the high pressure that the material filling utilizes extrusion storage vat oil gear to produce the plastics of setting weight given as security in the mould, plastics get into mould via valve, lasting pressurize is filled up, extruder uninterruptedly turns round simultaneously; Plastics are given as security into the deposit storage vat, opened valve after filling finishes, extrusion storage vat oil gear withdraws from; Deposit storage vat oil gear give as security into, the plastics of extruder get into the extrusion storage vat with the plastics of deposit storage vat, inclined-plane, first section axle center left in advance when extrusion storage vat oil gear withdrawed from; Air can get into the interior plastics of storage vat and contact generation vacuum when avoiding second section of oil pressure to withdraw from via the bellmouth that bores; Because extrusion storage vat oil gear withdraws from, the plastics high pressure is no longer to the mould pressuring direction, and the back pressure that produces is blocked the material hole after valve is pushed to; Keep the mould inner high voltage, wait for the finished product cooling, extruder is still continual simultaneously gives as security into plastics to storage vat; Behind the product cooling and shaping, the thread of outwarding winding leaves by mould, at this moment gets back to the cycle period of step 1 again; (5), after the form removal product cooling, mould taken apart get final product.
The present invention realizes the device of above-mentioned technology; Comprise extruder and mould, it is characterized in that said extruder is provided with feeding-passage, be provided with an extrusion storage vat and at least one deposit storage vat along feeding-passage; In extrusion storage vat and the deposit storage vat oil gear is installed; Between extrusion storage vat and the deposit storage vat control valve is installed, on the said extrusion storage vat discharge nozzle that docks with mould is installed, discharge nozzle is equipped with valve; Said mould is by the male model core, be installed in master mold on the male model core, be installed in the male model plate of master mold one end, master mold header board and the rear pattern plate that is installed in the master mold other end constitutes, and rear pattern plate is provided with the import that supplies discharge nozzle to insert.
Above-mentioned male model core is provided with the auxiliary demoulding hole of male model air, and rear pattern plate is provided with the auxiliary demoulding hole of rear pattern plate air.
Be provided with the cooling duct in above-mentioned male model core, master mold and the rear pattern plate.
Above-mentioned valve can adopt non-return valve.
The invention has the beneficial effects as follows: adopt the plastic article of technological process manufacturing of the present invention can not receive the restriction of weight and shape, earlier the plastics of fusion are given as security into a special storage vat during injection moulding, arrive the weight that sets; With the plastics in the storage vat, all give as security in-mold molding, when waiting for cooling forming again; At this time extruder continues to storage vat extrusion storing, after the finished product cooling in the mould, carries out the form removal action again; Unload finished product after the form removal, again set of molds is installed, return the extrusion storage vat again the exit; Carry out another time again and inject plastics; Make next mould, adopt this technology manufacturing excess weight or complex structure article can reduce the die sinking expense, reduce the injection moulding cost.
