Detailed description of the invention:
Referring to Fig. 1 and Fig. 2, the automatic die sinking one-shot forming rotational molding vehicle body mould described in the embodiment of the present inventionTool, comprises male model 1, master mold 2 and mould bases 3, and male model 1 is realized by automatic open-close mechanism with master mold 2Die sinking and matched moulds. Also comprise headlight active module 4, Rear lamp for vehicle active module 5, car door movable moldPiece 6, headlight active module slide rail, Rear lamp for vehicle active module slide rail, car door active module slide rail,Headlight active module drives locking device 7, Rear lamp for vehicle active module to drive locking device 8, car doorActive module drives locking device 9, and wherein, headlight active module 4 is driven by headlight active moduleThe relevant position that moving locking device 7 drives control to slip into master mold 2 along headlight active module slide rail is realNow locking, Rear lamp for vehicle active module 5 drives locking device 8 to drive by Rear lamp for vehicle active module and controls edgeRear lamp for vehicle active module slide rail slip into master mold 2 relevant position realize locking, car door active module 6 byCar door active module drives locking device 9 to drive to control and slips into master mold 2 along car door active module slide railRelevant position realize locking.
Headlight active module drive locking device 7, Rear lamp for vehicle active module drive locking device 8 andCar door active module drive locking device 9 include the first driving cylinder 71,81,91 and two support arms 72,82,92, wherein, one end of two support arms 72,82,92 is hinged by bearing pin 73,83,93Together, the other end of two support arms 72,82,92 respectively with mould bases 3 and corresponding active module 4,5,6 be flexibly connected the piston rod upper end of the first driving cylinder 71,81,91 and bearing pin 73,83,93Connect. When work, the first driving cylinder 71,81,91 upwards promotes, and support arm 72,82,92 is receivedClose, each active module 4,5,6 skids off master mold 2 realizations along the slide rail corresponding with it and opens; Otherwise,The first driving cylinder 71,81,91 is downwards time, and support arm 72,82,92 opens and stretches, each active module4,5, the 6 edge slide rails corresponding with it slip into the relevant position realization locking of master mold 2, make mould notCan slide because of follow-up rotation.
On male model 1, be provided with inner core pulling active module 10, inner core pulling active module 10 is by the second drivingCylinder 11 drives. After male model 1 and master mold 2 matched moulds, inner core pulling active module 10 ejects, so that becomingThe reinforcement that forms a kiss formula structure after type in the hollow sandwich of plastic body cover, improves plastic body coverIntensity, prevent that the situations such as contraction, distortion and warpage from appearring in plastic body cover.
The first driving cylinder 71,81,91 and the second driving cylinder 11 are high temperature-resistant cylinder, and respectively driveCylinder 71,81,91,11 is equipped with and advances the limit and retreat limit contactor control system. When work,Advancing and retreating and can carry out successively separately of each driving cylinder also can be carried out simultaneously.
The automatic open-close mechanism of male model 1 and master mold 2 can be arranged on the crane liter of male model 1 lower endFall opening-closing structure, also can be arranged on the air cylinder driven opening-closing structure between male model 1 and master mold 2.
Between the die joint of male model 1 and master mold 2, be provided with the location fit structure 12 of pin and pin-and-hole,Make mould close up location, prevent that mould from moving in heating rotary course.
In mould, be provided with pressue device, when mold heated and inflating pressure while being cooled to certain one-phase.At raw material, during also in loose condition (of surface), pressurization contributes to die venting and reduces Bubble formation, raw materialCompacting also fully contacts, conducts heat with die surface more completely, accelerates cooling contraction, reduces warpage.Improved the intensity of plastic body cover, the shortening cycle reaches 20%, and the highest improvement impact strength reaches 20%. SuitableTime pressurize can also make surface Paint Gloss, produce high-precision plastic body cover.
In mould, be provided with heater, mode of heating comprises directly-firing heating, infrared heating and electricityPower heating etc. Can whether heating condition be suitable, be obtain most important of good rotational moulding vehicle bodyOne of part. Reasonably heating condition is not only to have appropriate heating-up temperature and time, andEnsure that each position of mould is heated evenly in whole forming process. This mold adopts liquefactionGas heating, this is the most frequently used mode of heating, carries out mould by the air heat to heating clamberHeat conduction.
In mould, be provided with cooling device, it is extremely important to rotational moulding process, because it is to final vehicle bodyPerformance and behavior have a great impact. It is cooling cold with water smoke that cooling mode generally includes airBut. In fact, cooling fast, for example, mould is just out just cooling with cold water from heating clamber,Can cause crystalline growth to be stagnated, the normal crystallization forming when cooling with natural speed far below meltDegree. Final crystallization degree will be reflected in the density of object. Water-cooled makes goods close fastDegree reduces, and the cooling extrudate density that makes of air increases slowly, sticking up of the slow cooling vehicle body of air in additionBent minimum with distortion. This mold adopts air cooling.
In mould, be provided with temperature measuring equipment in mould. Accurate Measurement can not be carried out and control is to temperature in mouldHinder a very large bottleneck of rotational moulding technical development. In mould, variations in temperature is determine and improve processing weekThe key factor of phase length and quality of item, the gas that common problem has warpage, gas expansion to formHole etc. Control for the inside and outside wall thickness to vehicle body, must control mould inside temperature in real timeDegree, forms the temperature curve of different periods, thereby ensures the quality of vehicle body.
Also comprise an automatic monitoring whether putting in place in order to monitor male and female mould and each active module matched mouldsControl device, in the time there is the phenomenon that matched moulds does not put in place, automatic monitoring device will send chimes of doom, carryShow that operating personnel overhaul in time, guarantee to use safety.
Above-described embodiment is used for illustrative purposes only, and is not limitation of the present invention, relevant skillThe those of ordinary skill in art field, without departing from the spirit and scope of the present invention, also canTo make a variety of changes and modification, therefore all technical schemes that are equal to also belong to category of the present invention,Scope of patent protection of the present invention should be limited by each claim.
