Fig. 1 is the perspective view as the injecting molding die that is used for inlet manifold of preferred embodiment of the present utility model.
Fig. 2 is another perspective view as the injecting molding die that is used for inlet manifold of preferred embodiment of the present utility model.
The specific embodiment
Usually, the common cylinder number of automobile engine has 3,4,5,6,8 cylinders.The engine of discharge capacity below 1 liter used 3 cylinders always, and the engine about 1.5 liters is generally 4 cylinders, and the engine about 3 liters is generally 6 cylinders, is 8 cylinders about 4 liters, uses twelve-cylinder engine more than 5.5 liters.Present embodiment is the inlet manifold mould of plastics of 4 Cylinder engines.
Introduce the product structure and the reparation of product problem of inlet manifold below.Inlet manifold comprises upper casing, mesochite and lower casing.Upper casing has welding muscle and air flue face.For the welding muscle, during the work of ultrasonic vibration friction welding machine, the welding muscle corresponding with mesochite produces high-temperature fusion in vibration at high speed, the formation sealed hollow thereby two welding muscle faces are bonded together effectively, so the welding muscle requires smooth-going, step can not be arranged, and solder side requires to make overall electrode as far as possible, prevents from that the EDM discharge from adding to go wrong man-hour.And the EDM degree of depth must reach the digital-to-analogue requirement, can not made allowance.Frictional force when vibrating in order to increase, welding muscle face requires to stay the spark line.For the air flue face, during engine operation, gas mixture enters in the cylinder via these air flues.So the air flue face requires fairing, can not have tangible step to play level,, cutter can not occur playing or cross and phenomenon such as cut so no matter be that EDM processing or CNC processing must be guaranteed these.Resistance do not occur in order to ensure gas mixture, the air flue face requires smooth, must reach minimum 1000# sand paper.The air flue face can be made straight body but back-off must not be arranged, and must be noted that when the early stage product analysis.The another side of upper casing is generally the visible face of inlet manifold, and common customer can require surface erosion line.And these faces are generally the back die face of mould, thus unavoidably have thimble, thus require thimble smooth-going, and must carry out anti-rotation.
Generally be provided with steel bushing fixing hole, ozzle, seal groove, big flange face and air flue hole on the mesochite.For the steel bushing fixing hole, the steel bushing of need colding pressing after the injection moulding moulding in this hole, the inlet manifold that soldering group is installed with bolt is fixed on the engine cylinder-body again, so the position degree for the steel bushing hole is had relatively high expectations, but because the contraction instability of the thick bigger and whole big flange face of glue of big flange face, so the position in steel bushing hole is also unstable usually, behind the die debugging parameter stability, need to adjust the position in hole, must consider so that revise during design.For ozzle, ozzle is used to connect flexible pipe, and general ozzle all can have back-off to be used for fastening flexible pipe to prevent to come off.So require the parting line of ozzle can not be too obviously and batch cutting edge of a knife or a sword definitely can not be arranged, otherwise cut the damage flexible pipe easily.Consider preferably during design that the position of assembling does not have parting line.For seal groove, be used for welding herein and finish back assembling sealing ring, consider that transportation after the assembling prevents that the sealing ring vibration from dropping, so the inwall all around of seal groove can not have too big gradient.The degree of depth of seal groove directly has influence on sealing effectiveness simultaneously, so the degree of depth of seal groove is also extremely important.For big flange face, have relatively high expectations for flatness, if these two facial disfigurements equally also can have influence on sealing effectiveness too greatly.For the air flue hole, the requirement the same with the air flue hole of upper casing.For some complicated inlet manifold, also have oily rail hole and oily rail support fixing hole on the mesochite.For oily rail hole, its atomizer with the band sealing ring links to each other, so the requirement in aperture is very high, just can not be too tightly when requiring the assembly lube rail pine too, while is in order to ensure the sealing effectiveness of oily rail, the circular degree in this hole also has higher requirement, and requires high polish to reach 1000# sand paper at least.For oily rail support fixing hole, the effect of 2 oily rail support fixing holes is that oily rail support correctly is fixed on the inlet manifold, so their position degree is extremely important with respect to 4 oily rail holes, and little with other structural relation.
The same welding muscle and the air flue hole that said function is all arranged with upper casing of lower casing is so require with upper casing also roughly the same.
The plastic material that the inlet manifold mould adopts is generally PA6+30%GF.This material mobile better, so occur easily being stranded bad problems such as gas, batch cutting edge of a knife or a sword, so exhaust is wanted fully during the mould design.The every interval 30MM of the die joint air drain that need begin to rehearse must be done the mold insert exhaust for the dark bone of sealing, and air discharge duct size stock size is the dark 0.02MM of wide 6MM.
As illustrated in fig. 1 and 2, injecting molding die of the present utility model comprises: cover half, dynamic model, running gate system, cooling system, mould emptier and oil cylinder.Cover half has the cover half core.Dynamic model has dynamic mould core.Dynamic model comprises panel 1, hot runner manifold 2 and the front template 3 that is linked in sequence.Running gate system is arranged in the hot runner manifold 2.Dynamic mould core is arranged on the side towards cover half of front template 3.Cover half comprises rear pattern plate 4, mould pin 5 and the base plate 6 that is linked in sequence.Mould emptier is arranged between rear pattern plate 4 and the mould pin 5.The cover half core is arranged on the side towards dynamic model of rear pattern plate 4.The closed time limit of cover half and dynamic model is shaped as the die cavity of mesochite.Running gate system has the hot flow path that holds the melt plastic cement that flows into die cavity.Cooling system is provided with first cooling duct that is used for die cavity and second cooling duct that is used for hot flow path.
Most of product structure complexity of inlet manifold and product are various, thus the mould of inlet manifold complex structure too, and also the mould structure of each money is widely different.Below with each functional part division mould structure of inlet manifold product.Big flange is worn oily rail hole, but the air flue hole structure consistent with the depanning direction, this structure need be done loose core of oil cylinder fuel-displaced rail hole and oily rail support fixing hole.Big flange is worn oily rail hole, but the air flue hole structure consistent with the depanning direction, this structure need be done loose core of oil cylinder fuel-displaced rail hole and oily rail support fixing hole.Also be provided with oily rail hole and oily rail support fixing hole on the big flange face of mesochite, at this moment, injecting molding die also comprises the oblique top core-pulling mechanism that is used for moulding oil rail hole and oily rail support fixing hole, and the oblique top core-pulling mechanism is connected with oil cylinder power.Big flange is worn oily rail hole, and air flue hole, big flange face and the inconsistent structure of depanning direction, and this structure need be done loose core of oil cylinder fuel-displaced rail hole and oily rail support fixing hole, needs oblique top or the row oily rail hole of loosing core in addition.In addition, when being arcuate socket in the air flue hole of mesochite, injecting molding die correspondingly is provided with the rotation core-pulling mechanism, and the rotation core-pulling mechanism is connected with oil cylinder power.Big flange is worn oily rail hole, and the air flue hole is the structure of arcuate socket, and this structure need be done loose core of oil cylinder fuel-displaced rail hole and oily rail support fixing hole.Mesochite has big flange face, air flue hole, is arranged on oily rail hole and oily rail support fixing hole on the big flange face, big flange face, air flue hole favour the depanning direction, and injecting molding die is provided with corresponding big flange face forming module in position and the air flue hole forming module with big flange face and air flue hole; Injecting molding die also comprises the oblique top core-pulling mechanism that is used for moulding oil rail hole and oily rail support fixing hole, and the oblique top core-pulling mechanism is connected with oil cylinder power; The air flue hole of mesochite is an arcuate socket, and injecting molding die correspondingly is provided with the rotation core-pulling mechanism, and the rotation core-pulling mechanism is connected with oil cylinder power.
The inlet manifold product also is easy to generate moderate finite deformation than the material of complexity and product, so advance the emphasis of the design of glue point for a whole set of mould design.Advance glue point design following principle is arranged: advancing glue point, must to guarantee that each air flue advances glue even, usually 1 of each air flue advances the glue point, many positions are advanced toward few position, glue position from the glue position, enter the position thin toward the glue position from thick position, glue position, can not there be weld mark or tired gas in the position relevant with air flue, otherwise can have influence on the burst pressure of product.Select product deformation effect minimum advanced the glue mode according to mold flow analysis.All advance glue point and must make the mold insert structure, so that the Jiao Kou position of postorder or the adjustment of size dimension.Adopt flat side gate or needle valve cast gate directly at the enterprising glue of product, help injection moulding like this and fill.Generally the inlet manifold mould does not adopt the mode of a Jiao Kou or latent Jiao Kou to advance glue.Cast gate must be easily broken, and the fracture cross section must be smooth.Dimension reference: dark 1.5～2.0MM, wide 4～8MM, concrete size is looked the product size.
The melt temperature of this material of PA6-GF30 reaches about 260, and PA6-GF30 is a kind of of engineering plastics, also is nylon list 6, and contains 30% reinforcing glass fiber.The temperature of mould also reaches about 80 degree, and the while glue of product is thick, and (2.5～3MM) and very inhomogeneous, the thickest glue is thick can to reach about 8～10MM, so cooling is equally also extremely important for the inlet manifold mould.Fortune water design also has following principle: front and back core rod fortune water from the glue distance of positions from for about 20MM, and even as far as possible, the position that can adopt the well cooling to protrude.Every fortune water can not be oversize apart from length, and every group fortune water well quantity can not be above 4.The water channel diameter is not less than 12MM, and the well diameter is not less than 20MM, does big as far as possible; The position thick for local glue position or heat is concentrated, cooling must be abundant, can consider with the splendid logical fortune of the beryllium copper mold insert water of radiating effect the heat of assembling to be taken away; Because the heating-up temperature of TOP-TIP is too high, so must there be one group of independent fortune water that TOP-TIP is cooled off.But it is noted that all die face that match with TOP-TIP are the least possible in order to prevent the thermal loss of TOP-TIP, particularly hot muzzle sealing face about general 5MM, occurs easily then too much that hot mouth is gaged somebody or problem such as mouth of a river sticking to mould.Because mold temperature is higher, A/B plate and hot runner manifold 2 will be transported water cooling usually, prevent in process of production that Yin Wendu is too high or the temperature difference is inconsistent and damage guide pillar or other precision part.Each row position and oblique top as far as possible all will have the fortune water cooling, and the water channel diameter is not less than 8MM.
Because the hardness of PA6-GF30 material is higher,, it should be noted that to eject and want balance so the inlet manifold mould generally can not occur pushing up phenomenon white, that rise.
