The specific embodiment
Pipe molding apparatus 1 shown in Fig. 1 comprises an extruder 3, and this extruder sends to plastic ripple forming machine 7 with the plastics of fusing by mould 5.Plastic ripple machine 7 comprises the ring-type formation 13 below ring-type formation 11 above of model block section and, these two formations are walked just to form a model duct together and can be admitted the plastics of fusing to make it form a plastic tube 9, and this plastic tube is discharged from the downstream in model duct.
Fig. 2 illustrates model block section 17 and is installed to by model block section conveyer chain 15 in the top formation 11 of corrugating machine, and model block section 21 is transported in the following formation 13 that chain 19 installs to corrugating machine.The model block section of these upper and lower formations all moves through model duct 14 on the direction of arrow A.Each model block section label 17 as shown in Figure 2 all has a front F and a back R to face the direction that model block moves through the model duct.
Have an air plenum to extend along the length in model duct, its purpose will describe in detail in the back.
Fig. 3 illustrates a front of going up a model block section 17 and a drag piece section 21.The parting surface 22 of last model block Duan Youyi parting surface 18 and drag piece section is connected to form the model block of a complete closed, become inside tube forming model district 24 in it, the vacuum that the shaping or use of pipe is pumped into by the fine gap in the model block section in this district or positive air pressure is incorporated in this district with blow moulding.
Fig. 3 illustrates model block and have the first and second side surface S on two offside between its front surface and the rear surface.Cooling system 31 is fitted on each side surface of model block.
Cooling system 31 has a labyrinth type raceway groove and comprises main groove 43 and less important groove 47 and 51.As seen in Figure 3,45 places of groove 47 between two grooves are with the direction counter-rotating of groove 43, and 49 places of groove 51 between two grooves are with the direction counter-rotating of groove 47.
Main groove 43 has a unlatching 41 to enter between the closed side, wherein a side is directly to be fixed on the side surface of model block by a pair of installing plate 33 and 34 to form, and opposite side is to be formed by 45 places that plate 35 hangs down between main groove 43 and the less important groove 47.
Less important groove 47 is formed at its opposite side 37 at one side and plate 37 by plate 35.Plate 37 terminates in raceway groove 49 places, and another less important groove 51 is formed at its opposite side or the outside in one side and plate 39 by plate 37.
Wai Ce less important groove 51 inwardly redirect to a short and horizontally extending groove 53 in the embodiment shown in fig. 3, and this raceway groove terminates in raceway groove and exports 55 places.Open to the inboard of model block at this ditch road junction, and be connected with 59 with vacuum pipeline 57, and the latter is connected with main vacuum pipeline 61 again.
From above explanation as seen, the labyrinth of groove comprises the groove that a plurality of side closed ends are opened, and these grooves offside to model block on vertical direction extends.
As once mentioning in the past, there is an air plenum 23 to extend along the length in model block duct.The cooling air just 23 flows to model block from the pumping chamber when each model block moves through the duct, and the cooling air is that the unlatching mouth 41 by main raceway groove 43 is input in the raceway groove labyrinth.This raceway groove is the most approaching groove of side surface of model block, and it admits the coldest air.This is air has maximum cooling effect to model block place.
Because how many initial coolings is slightly heated, and reverse directions is upwards by groove 47 then, reverse directions is downwards by groove 51 again when air flows into by groove 43.Warm when so far though the air ratio initially enters groove 43, but still colder than the extraneous air around the model block, therefore to the still old cooling effect of model block.
Cool off in the embodiment shown in fig. 3 air by vacuum attraction to the cooling labyrinth in.This vacuum is exactly vacuum such as the vacuum forming of product and/or the inner vacuum cooling of model block that is used to control other functions of model block.As what mentioned in the past, this vacuum is to attract by the raceway groove 57 and 59 that directly is connected with the port of export 55 in raceway groove labyrinth 31 from main vacuum pipeline 61.
Should be noted that from Fig. 3 raceway groove labyrinth 31 is adapted to by the existing transformation that does not possess the model block of external refrigeration details easily.As long as two boards 33 and 34 directly are fixed on the outer surface of model block.This two board is separated from each other just to can be used to make upper and lower two model block sections to open and closure.
Can see from top explanation this model block respectively is how constantly to accept to be trapped within cooling air between the model block opposite flank when model block moves through the model duct.
Fig. 4 illustrates one by last model block section 65 and the model block that drag piece section 67 is formed.Raceway groove labyrinth 71 is contained on each side surface of this model block.
Entering the labyrinth in this embodiment must be by the mouth 75 of a main groove 77 of guiding, and the ditch road junction 79 of less important groove 81 is then passed through in the outlet in labyrinth.Be provided with an inner port 80 between the groove 75 and 79.Therefore cooling off air mobile in the labyrinth is, through port 75 enters, and flows along main groove 77, and is reverse by the internal access road junction, flows along groove 81, and air is discharged from the labyrinth at mouth 79 places then.
With air among the embodiment shown in Figure 3 be by vacuum suck different, the cooling duct that flows through of air is to be finished by a positive air pressure source outside in the embodiment shown in fig. 4.
Cooling groove channel shown in Fig. 3 has three cooling groove channel portions, and the cooling groove channel shown in Fig. 4 has two grooves.Will be appreciated that to have more groove, but also can be only with a groove.In addition, an independent groove can be operated by vacuum or by positive air pressure.In either case, groove is directly to extend along the side surface of model block, and cooling medium is preferably refrigerating gas and is trapped and makes model block obtain the contact cooling there.
In the embodiment of explanation up to now, all parts of cooling groove channel all are that each side surface along each model block vertically extends.This cooling groove channel can all seal on all three sides, has only the two ends of raceway groove to open.In this configuration, the cooling air is separately to each model block.
In another scheme of the present invention, the cooling groove channel of each each side of model block all is just opening at the front side and the rear side of each model block as shown in the figure of upwards sealing in the footpath of each model block.This configuration makes the cooling air transfer to another model block from a model block along the model duct, but keeps key of the present invention, and air still is trapped and makes model block and not along the effusion radially outward of model block.
Fig. 5 illustrates another preferred characteristics of the present invention.Specifically, Fig. 5 illustrates a model block of being made up of last model block section 91 and drag piece section 93, in Fig. 5 the front of model block towards outside.
Two offsides in model block are provided with a plurality of fluid media (medium)s admittance raceway grooves 95.These raceway grooves are stopped as the border by a wall that extends on the vertical direction of each model block section 96 along its inner surface.Wall 96 provides a public assembly wall for each raceway groove 95.
Raceway groove 95 is covered by one second wall in the outside.
In this embodiment, raceway groove 95 along continuous straight runs extend, and promptly rearward extend from the place ahead of each model block.They need not be connected to each other, but each raceway groove admits cooling air separately to flow.This air is offered by the air plenum of extending along the length in model duct and opens mouth 99, flows to all raceway grooves by opening mouth again.
The embodiment of Fig. 5 is such characteristics with the consistent place of embodiment of previous explanation, promptly cools off air and is trapped along the side surface of model block, does not allow its outwards flow at once and leaves model block.
Though the present invention describes in detail with regard to each preferred embodiment in the above, should know that under the condition of not leaving intention of the present invention and claim institute limited range, those skilled in the art still can make various variations to the present invention.
