Fig. 1 is the schematic perspective view as the gas assisted molding mould that is used for the automotive trim door-plate of preferred embodiment of the present utility model;
Fig. 2 is the structural representation of automotive trim door-plate.
The specific embodiment
As shown in Figure 1; the gas assisted molding mould that is used for the automotive trim door-plate comprises cover half, dynamic model, running gate system, cooling system, mould emptier and oil cylinder; cover half has the cover half core, and dynamic model has dynamic mould core, and 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.Dynamic model 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.Dynamic mould core is arranged on the side towards cover half of rear pattern plate 4.The closed time limit of cover half and dynamic model is shaped as the die cavity of automotive trim door-plate.Running gate system has the hot flow path that holds the melt plastic cement that flows into die cavity.This body by integral forming of map pocket and automotive trim door-plate.
The material of automotive trim door-plate adopts PP-TD20, and its shrinkage factor is 0.95%.Its appearance and size big (long 846mm, wide 620mm, high 150mm), yielding, be unfavorable for product size control.In addition, in the processing and forming, the difference of this interior trim door-plate body and common interior trim door-plate is, map pocket product simplification structure and main body characteristic are organically combined the formation one, can exempt to do the map pocket product through one-shot forming, also can remove assembling process from and reduce the assembling use anchor clamps, thereby effectively save installation time, fund and resource.
For this automotive trim door-plate, has width 6.0mm, degree of depth 100mm, the simplification map pocket product assembling of length 900mm is with dark muscles and bones 7 (as shown in Figure 2), so need the gas assistant formation, Shooting Technique requirement height, need jacking block to eject dark muscles and bones, cause the mould structure complexity; Product one side direction in addition, what different directions arranged can not the depanning position, needs the slide block of design different order to go out mode structure, satisfies the depanning requirement of product.For this reason, the product structure that this cover is complicated, the mould design difficulty is big, and crudy requires high, and the requirement of Shooting Technique is harsh more.
At first, in order to satisfy the product external surfaces quality, satisfy dermatoglyph and reach best effects, big in conjunction with the etching characteristic and the die size of die steel, the assessment of combined factors such as complex structure is all selected import 738 die steels for use to solid plate/moving platen.
The second, consider that product size is big, appearance requirement is high and satisfy the auxilliary technological requirement of gas, has adopted the hot mouth injection moulding of oil pressure needle-valve order, and 5 are advanced glue.Through PS injection moulding situation, product appearance does not have weld bond, and speaker enclosure place outward appearance is good, not the defective that causes because of the injection moulding reason.
The 3rd, simplify the map pocket product with dark muscles and bones gas assistant formation technology: during design,, economize on resources and cost, map pocket product and door-plate body are designed to one, so the dark muscles and bones of map pocket shape need be adopted gas assisted molding in order to reduce Assembly part.Design for air inlet: because the total length of air flue reaches 900mm, blow logical dark muscles and bones bottom, ensure that product appearance is good, adopted two air tube air inlets in order to guarantee that very little air pressure can satisfy when the injection moulding.Two regioselective principles of air inlet are to guarantee that the length of four sections air flues is approximately equal, air pressure balance.Air-flow impacts to the cover half direction when common air tube is blown, and causes the gas trace of product surface, needs to change the gas outlet direction of air tube.Assist technology (being blown into nitrogen) for gas: for the appearance of the dark muscles and bones correspondence of product, the vestige minimum behind gas assisted molding is outside the change of degasification needle construction, also need to control the maintenance of mould temperature, air inlet total time, the air inlet gas pressure and the inlet period in different pressures stage lose heart the time etc.In conjunction with practice in the product injection moulding process, cover half mould temperature need be remained on the 35-40 degree; Dynamic model mould temperature guarantees the degree at 30-35; The beginning injection moulding, pressurize is blown, and die sinking is lost heart in cooling.Wherein, lose heart preceding 1.5 seconds time in die sinking.The Cooling Design of dark muscles and bones both sides: because dark muscles and bones is dark, it is big to gather heat, and mould temperature rise temperature speed is fast, so, on the both sides of dark muscles and bones, adopt cooling water as much as possible to cool off, and, adjust to the 10-15 degree inflow temperature, guarantee that the mould temperature is at the 30-35 degree.
By above measure, can guarantee that dark muscles and bones place deflection is little, dark muscles and bones depanning is smooth and easy, reduces cool time, allows gas assist process stabilizing, makes dark muscles and bones place product surface quality good, ensures the product percent of pass height.
The 4th, the slide block depanning structural analysis of different order: the reason of slide block depanning structural design different order: Surface Appearance need corrode decorative pattern, so separately do two or three slide blocks as this side of fruit product, will make and stay edge on the appearance of product and piece together line, after the entrucking, obviously as seen the product appearance defective can cause outward appearance not attractive in appearance, gives the ropy sensation of user.So, piece together line in order to reduce outward appearance edge, adopted on master slider, design " tunnel type " slide block allows the potted line of slide block, walks along the outer edge of product, satisfies the high-quality requirement of appearance.In order to solve master slider and to divide slide block, reach relation between the action of folding mould, by analysis, master slider is adopted cylinder action, and the control master slider is introduced into before matched moulds and puts in place, after the injection moulding die sinking, before ejecting product, take out out slide block again and retreat and put in place, reach normal injection moulding requirement; The branch slider designs is installed in the master slider, when master slider before matched moulds, be introduced into put in place after, matched moulds will divide the slide block matched moulds to put in place by cover half limit shovel machine; During die sinking, divide slide block to utilize Angle Pin and catapult, before taking out out prior to master slider, retreat into the position earlier; And then rearward move with master slider together, reach normal injection moulding requirement.The cooling of master slider: because the glue plane that is on the product is long-pending big, the degree of depth is dark, thus adopt two groups of cooling waters, and, increase deep mixed cooling well according to shape of product, and guarantee the evenly cooling of mould temperature, shorten molding cycle, reduce the product distortion.
The 5th, speaker enclosure place structural analysis:, speaker enclosure mold insert material is accomplished with the same material of cover half: import 738 for the body colour contrast of speaker enclosure presentation quality after with dermatoglyph is little; To the thousands of holes that amplify, speaker enclosure place, adopt " graphite " electrode, time processing puts in place, and the presentation quality of avoiding additional electrode to cause is bad.Then, use the accurate spark machine of minute surface, the long-time discharge processing of little electric current (3A), the hole dimension of accomplishing to amplify is even, indeformable, accomplishes electric spark outer surface decorative pattern uniformity, appearance looks elegant.Ensure the design main points of speaker enclosure injection moulding production requirement: 1. smooth and easy, and guarantee injurious surface mark not occur having under the situation of smooth cut for the speaker enclosure hole depanning that amplifies, so, the depanning gradient on the cover half limit, hole that amplifies is accomplished 10 degree/monolateral; The depanning gradient on dynamic model limit accomplish 7 the degree/monolateral; Dynamic model limit glue is thick account for total glue thick 2/3.2. the speaker enclosure mold insert all designs cooling water separately separately, and the mold insert temperature remains on the 40-45 degree when guaranteeing to produce, and it is smooth and easy to ensure that speaker enclosure is walked glue, the starved phenomenon do not occur; 3. for fear of burning and few glue that the tired gas of speaker enclosure causes, need determine last melten gel position according to mold flow analysis, in the end the melten gel position increases " exhaust steel " mold insert; In addition, at speaker enclosure mold insert edge, do the air discharge duct in a week, guarantee that exhaust is smooth and easy, it is smooth and easy to guarantee that melten gel flows.
By the control mould strength, product advances the glue balance, ensures that the production action is smooth and easy, satisfies the Shooting Technique requirement, makes product quality reach requirement.
As mentioned above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
