ている。That is, since the cooling air is blown from below the parison, only the lower end of the parison is locally cooled, and the inner surface of the parison is not cooled, so the temperature difference between the inner and outer surfaces increases. As described above, if the temperature of the parison becomes non-uniform, the wall thickness of the stretch blow molded product will become non-uniform. In addition, cooling takes a long time because cooling cannot begin until after the moving table has moved to the top of the air jet pipe, and the air jet pipe cannot be brought extremely close to the parison. The present invention solves the above-mentioned problems and provides a parison cooling device that can cool the parison efficiently and uniformly in a short time. It is an object.

Solve the points. That is, the parison cooling device according to the present invention has an air chamber provided on a movable table that can move between the parison molds and the outside, and the air chamber includes a first chamber housing the parison and its outer periphery. The partition wall between the first and second chambers is made of a porous material that allows air to flow, and the second chamber has temperature-controlled air. The cooling air can be supplied from the cooling air supply device through a flexible hose, and the Ml chamber is connected to the atmosphere through an air outlet, and is provided with a cooling air blowing core made of a porous material that can enter the inside of the parison of the movable platform.

ことが可能となる。(E) Function When the parison molded by the parison mold is inserted into the first chamber on the movable table and the movable table starts moving, cooling air at a predetermined temperature is supplied from the cooling air supply device to the second chamber. be done. The air in the second chamber passes through the cylindrical porous material partition wall, flows into the first chamber from the entire circumference, cools the parison, and is then discharged to the outside from the air outlet. At the same time, a cooling air blowing core made of a porous material is inserted into the inside of the parison, and cooling air is uniformly supplied to the inner surface of the parison. The parison is therefore uniformly cooled from both its outer and inner surfaces. Since cooling air is supplied to the second chamber through the flexible hose, the parison can be cooled even while the moving platform is moving, and the cooling time can be shortened. In addition, the cooling efficiency is high because all the cooling air supplied to the second chamber passes through the first chamber and is discharged after cooling the parison. Note that the cooling air blowing core made of porous material may be installed independently. However, if it is provided integrally with a gripping device for transferring the parison, it becomes possible to cool the parison even while transferring it to a heating furnace for temperature adjustment.

When the parison 24 is inserted into the first chamber 26, the flexible hose 33 and the air supply port 32 are immediately
The second room through? Cooling air is supplied into the 8. The cooling air in the second chamber 28 enters the first chamber 26 through a small hole in the porous partition wall 30, passes around the parison 24, cools it, and is then discharged from the air outlet 31. . Further, at the same time as the parison 24 is inserted into the first chamber 26, the air cylinder 20 is activated, and the moving table 16 moves to the left in FIG. 1 and returns to the position of the fifth parison cooling section 6.

That is, when the movable table 16 stops at the parison cooling section 6, the cooling air blowing core 37 descends, and as shown in FIG.
Enter 4. Temperature-adjusted cooling air is discharged from the entire outer surface of the cooling air blowing core 37. Therefore, the parison 24 is uniformly cooled from both the inner and outer surfaces. Next, after a predetermined period of time has elapsed, the parison 24 is transferred by a gripping device (not shown) into the temperature control heating furnace 38 of the Parin temperature control #gss. The parison 24 is adjusted to the blow-through blow molding temperature in the temperature adjusting heating furnace 38. When the temperature of the parison 24 is adjusted to the blow-molding temperature, the parison 24 is sent to the stretch-blow blow-molding section by a gripping device (not shown), where stretch-blow-molding is performed. A hollow molded product is thereby obtained.

ることができる。As mentioned above, the parison 24 is cooled from both the inner and outer surfaces by the cooling air uniformly supplied from the porous partition wall 30 and the cooling air blowing core 37, so the temperature unevenness becomes very small. Since the temperature is further uniformly adjusted in the heating furnace 38 for temperature adjustment in the process, and then stretch blow molding is performed, the thickness of the molded product becomes uniform, and the incidence of defective products is significantly reduced. Also, parison 2
Cooling of the parison 24 is started at the same time as the parison 24 is installed in the first chamber 26, and is also cooled while the moving table 16 is being moved. Therefore, the cooling time can be shortened by that much, and the molding cycle can be shortened. be able to. In addition, since all the cooling air supplied to the second chamber 28 passes through the first chamber 26 and is discharged from the air outlet 3■, the entire amount of cooling air is used effectively, resulting in high cooling efficiency. It can also shorten the cooling time.
