The specific embodiment
Below be preferred embodiment of the present invention, but therefore do not limit protection scope of the present invention.
With reference to Fig. 1, shown in Figure 2, a kind of blow mold of blowing hollow spare tyre cover plate, comprise cover half cavity plate 1 and the dynamic model cavity plate 2 that matches with cover half cavity plate 1, dynamic model cavity plate 2 back sides are fixed with many dynamic model cavity plate support columns 21, and many dynamic model cavity plate support column 21 free ends are fixed with dynamic model cavity plate fixed head 22; Cover half cavity plate 1 back side is fixed with many cover half cavity plate support columns 11, and many cover half cavity plate support column 11 free ends are fixed with cover half cavity plate fixed head 12; Be provided with guider between dynamic model cavity plate 2 and the cover half cavity plate 1, cover half cavity plate 1 is provided with the die cavity of product to be formed, and described dynamic model cavity plate 2 or cover half cavity plate 1 are provided with the reinforcement shaped device.
On the guider stated be exactly that cover half cavity plate 1 is provided with guide pin bushing in fact, dynamic model cavity plate 2 is provided with the guide pillar that matches with guide pin bushing position respective amount equal shape size.
Described reinforcement shaped device is located on the dynamic model cavity plate 2.
Described reinforcement shaped device comprises gripper shoe 3 and the fixed head 4 that is connected with gripper shoe 3 slip bufferings, fixed head 4 is between gripper shoe 3 and dynamic model cavity plate 2, gripper shoe 3 cooperations are fixed on the many dynamic model cavity plate support columns 21 of dynamic model cavity plate 2, fixed head 4 inner surfaces are fixed with polylith reinforcement moulding push pedal 5, be penetrated with the gathering sill 23 that matches with reinforcement moulding push pedal 5 number same position correspondingly-shaped sizes on the dynamic model cavity plate 2, gripper shoe 3 is provided with the thrust unit that can order about reinforcement moulding push pedal 5 turnover gathering sills 23.
Fixed head 4 inner surfaces are fixed with polylith reinforcement moulding push pedal 5, are by stay bolt 41 reinforcement moulding push pedal 5 to be fixed on the fixed head 4.Reinforcement moulding push pedal 5 the present invention adopt rectangular shape, can certainly be other shapes.
Gripper shoe 3 cooperations are fixed on the many dynamic model cavity plate support columns 21 of dynamic model cavity plate 2, be meant and be penetrated with the support guide hole 31 that matches with dynamic model cavity plate support column 21 number same position correspondingly-shaped sizes on the gripper shoe 3, be fixed with fixed cover 211 on the part dynamic model cavity plate support column 21, fixed cover 211 adopts bolt and fixed by nut to link together with gripper shoe 3.Here the part dynamic model cavity plate support column of saying 21 is four in fact, as shown in Figure 2, forms a square.
In conjunction with Fig. 1, shown in Figure 2, present embodiment support guide hole 31 is total up to 12, is the right and left that two vertical setting of types are arranged on gripper shoe 3,6 vertical one-tenth one rows' of every row support guide hole 31.Fixed head 4 is littler than gripper shoe 3, and just fixed head 4 all is positioned within the gripper shoe 3, and fixed head 4 can move between gripper shoe 3 and dynamic model cavity plate 2 by the push-and-pull action of thrust unit 6, realizes the moulding of reinforcement.
Described thrust unit is the oil cylinder 6 of fixedlying connected with gripper shoe 3 outer surfaces, and the push rod of oil cylinder 6 penetrates gripper shoe 3 and fixedlys connected with fixed head 4.The push rod of oil cylinder 6 and gripper shoe 3 are slidingly connected.
The connection of described slip buffering is meant that many bolts 7 run through gripper shoe 3 and fixed head 4 simultaneously, is with pad and nut 8 on bolt 7 afterbodys in gripper shoe 3 outsides, is with spring 9 and pad on the bolt shank between gripper shoe 3 and the fixed head 4.Here gripper shoe 3 adopts bolt, nut to be connected with fixed head 4.The cap portion of bolt is in fixed head 4 inboards, and just the cap portion of bolt is between fixed head 4 and dynamic model cavity plate 2.
Certain slidably distance is arranged between gripper shoe 3 and the fixed head 4 in fact here, is not to have tightened between the two.When oil cylinder 6 promoted fixed head 4, the slidably distance between gripper shoe 3 and the fixed head 4 was greater than or equals the required distance of work of the reinforcement moulding push pedal 5 on the fixed head 4.When the meaning that is to say the reinforcement moulding push pedal 5 shaped article reinforcements of this blow mold, gripper shoe 3 can not have influence on the work of reinforcement moulding push pedal 5.
Cover half cavity plate 1 upper end is provided with two pegs 13, is provided with in the front of cover half cavity plate 1 upper end horizontal parallel.Be used for the vermicelli material, described lining adopts needle punched non-woven fabrics.
Blow mold of the present invention, it all is the same having a lot of places with existing blow molding die, be provided with the die cavity of processed product such as cover half cavity plate 1, cover half cavity plate 1 and dynamic model cavity plate 2 junctions are provided with the blow needle hole, be convenient to the blow moulding machine blow needle and insert air blowing, connecting cylinder on the blow needle, as pump-down process on cover half cavity plate 1 and the dynamic model die cavity template 2 chamber faces etc.But the most outstanding inventive point of the present invention is exactly can also form reinforcement at interior of articles when can form hollow object, and this is that existing blow mold institute is irrealizable.
Blow mold of the present invention is not limited to specific certain product of processing, can the processing belt cavity and cavity in be provided with the product of reinforcement.Be example with the cover plate of spare tire of automobile of mentioning in the background technology below, how coming works to do further to blow mold of the present invention is set forth.
Operation principle of the present invention and job step are as follows: in conjunction with Fig. 1, Fig. 2, cover half cavity plate 1 is provided with two pegs 13, be used for the tuck prick nonwoven cloth, but blow moulding machine is extruded thermoplastic molding's plastics, form a required type embryo, the type embryo on cover half cavity plate 1 needle punched non-woven fabrics and dynamic model cavity plate 2 between the time, cover half cavity plate 1 and dynamic model cavity plate 2 matched moulds put in place moment, oil cylinder 6 promotes fixed head 4, gripper shoe 3 maintains static, and fixed head 4 and reinforcement moulding push pedal 5 are connected as a single entity with oil cylinder 6 motions, and oil cylinder 6 promotes fixed head 4 and also just means promotion reinforcement moulding push pedal 5, the gathering sill 23 on the dynamic model cavity plate 2 is passed in reinforcement moulding push pedal 5, the extrusion pressing type embryo was delayed time after 1～2 second, had at this moment formed reinforcement in the type embryo, oil cylinder 6 withdrawals that is to say reinforcement moulding push pedal 5 disengaging type embryos.Cylinder 15 drives blow needles 14 insert type embryos at this moment, starting blow needle 14 immediately blows, the type embryo of order expand in the die cavity of blow mold, to be formed is taken off after solidifying cooling, along die joint unnecessary material and lining are cut off, the cover plate of spare tire of automobile outer surface of moulding is also being pasted one deck needle punched non-woven fabrics like this.As Fig. 2, among the figure moulding cover plate of spare tire of automobile 10.Certainly, if do not want to paste lining (needle punched non-woven fabrics), can hang up lining in the product outside.So just formed the product of a band hollow cavity.
