Description
Technical field
The invention belongs to the manufacture field of rubber nylon skeleton, especially relate to a kind of processing mold of motor intake manifold rubber nylon valve block.
Background technology
Along with country is to the improving constantly of automobile exhaust emission standard and people's ideas of energy-saving, a kind of novel inlet manifold technology with two inlet channels is arisen at the historic moment.Its know-why is: in the time of gasoline engine low-speed running, engine, by conversion nylon valve block, makes air flow to cylinder along bending and elongated inlet manifold.Elongated inlet manifold has improved intake velocity, has strengthened the current rate in cylinder, air inlet charge is increased, thereby improved combustion process, has reduced fuel consume, has improved the dynamic property of gasoline engine, has improved effective output torque.In addition, variable-length intake manifold reduces the effect of gasoline engine discharge amount of exhaust gas in addition; In the time that high engine speeds turns round, by conversion nylon valve block, make air directly enter the inlet manifold of tubbiness.The inlet manifold of tubbiness, intake resistance reduces, and also makes air inlet charge increase.The realization of this technology is mainly to rely on nylon valve block long and short air intake duct is switched.
Rubber nylon valve block is to be combined by the peripheral bonding by Vulcanization fluorubber of polyamide skeleton part, working environment is impacted by air blast, once rubber burr comes off, to directly enter and start in cylinder, cause engine to damage, so must there is no rubber burr in rubber nylon valve block surface, and be arranged on inlet manifold turning because of it, so valve block profile is a complicated curved-surface structure.And the product that traditional rubber mold is produced, as long as will there be burr in apertured place, once and polyamide skeleton has not been wrapped rubber in encapsulate region, depending merely on secondary maintenance is to guarantee.Due to this technology just started at home starting, domestic rubber production manufacturer production is lacked experience, thus present stage this part be mostly import or produce at home for overseas-funded enterprise.
Publication number is production method and the vulcanization of rubber mould of the patent documentation of the 102962931A rubber clip that discloses a kind of interior bag skeleton, the method is that vulcanization of rubber mould is heated to after uniform temperature, the metallic framework that scribbles bonding agent in vulcanization of rubber section is placed in the locating slot of lower bolster of vulcanization of rubber mould, and hole on metallic framework and the locating hole of lower bolster are accurately located by locating pin, then cover cope match-plate pattern, add appropriate sizing material in reinforced chamber, be pressed into the after cure of note plug, sizing material is led and is entered die cavity by main flow like this, and form gum sleeve formed product in metallic framework outer wrapping.Make metallic framework and gum sleeve adopt rubber mold to be sulfided into one, metallic framework and rubber is connected firmly, reliably, overcome the problem such as distortion, internal clearance of product, and product quality improves greatly.The product that this invention is produced, cannot prevent from not needing the skeleton surface of rubber coating to produce burr.In addition, the mould structure that this invention is used is mainly for metallic framework, and is not suitable for polyamide skeleton part, because polyamide skeleton part is stressed excessive in the time of high temperature, easily deforms.
The patent documentation of notification number CN201632624U discloses a kind of rubber-alloy metal compound product.A kind of rubber-alloy metal compound product, it is mainly made up of alloying metal component and vulcanized rubber component, has then portion between described alloying metal component and vulcanized rubber component; Described then portion's periphery is provided with small rib, and this utility model, because the then periphery of portion of alloying metal component has designed and produced small rib, while adding sulphur, due to the compressed distortion of small rib, has strengthened sealing effectiveness, and rubber burr is difficult for producing; Simultaneously, because of the existence of small rib, mould has become line with alloying metal component by face contact angle and has contacted, because face contacts the body generation crack of the alloying metal component causing or the bad situation that ruptures no longer occurs; The manufacture of mould simultaneously also no longer needs special shape, has both reduced die manufacturing cost, has extended again the service life of mould.Processing by disclosed this patent technical scheme for motor intake manifold rubber nylon valve block, weak point is: the rib 1, protruding on skeleton easily produces irregular deformation after pressurized, thereby go into tiny metallic bur power, in the time that alloying metal part rigidity is excessive, also likely produce the minute metallic chip dropping, these two kinds of problems are fatal in plastics air inlet manifold branch of engine sealing; 2, the rib protruding on metallic framework can not be driven plain completely after pressurized, all the time can continue to employ a small amount of projection, these projections in the time that high engine speeds turns round, when valve block quickly opening and closing easily and inlet manifold friction, shock, produce noise, affect the serviceability of automobile.
Summary of the invention
