Technical Field
[0001] The utility model relates to the field of blow molding machines, in particular to a device for rapidly cooling and shaping blow-molded products. Background Art
[0002] A blow molding machine is a plastic processing machine. When the blow molding machine is running, the plastic is melted and quantitatively extruded in the screw extruder to obtain a plastic preform.

[0030] The upper fixing plate 5 is provided with upper oblong holes 46 symmetrical to each other on the left and right sides; the upper surface of the upper module 6 is provided with upper screw holes 47 corresponding to the positions of the upper oblong holes 46 on the left and right sides.
[0031] The upper cylinder mounting plate 3 is provided with a plurality of evenly distributed upper guide holes 48; the upper guide holes 48 are provided with matching upper guide sleeves 49; the upper surface of the upper fixing plate 5 is provided with an upper guide rod 50 coaxial with the upper guide sleeve 49, and the upper end of the upper guide rod 50 passes through the upper guide sleeve 49 upward.
[0032] The method of using the utility model is as follows:
[0033] After the blow-molded product 51 is blow-molded into the actual required shape in the mold, the mold will be opened directly. At this time, the clamping and transferring device on the blow-molding machine will be clamped in the middle of the blow-molded product 51, and the blow-molded product 51 will be transferred between the upper module 6 and the lower module 15. Since the blow-molded product 51 will undergo preliminary cooling when it is exposed to the outside world for the first time, it has a certain strength. The clamping force of the clamping and transferring device is not very large, but it can just play a clamping effect. Therefore, there is no need to worry that the clamping force of the clamping and transferring device will cause the blow-molded product to deform.
[0034] When the blow molded product 51 is located between the upper module 6 and the lower module 15, the upper cylinder 4 and the lower cylinder 13 can be started. When the upper cylinder 4 is started, the piston rod of the upper cylinder 4 will drive the upper module 6 to move downward through the upper fixed plate 5. When the upper module 6 moves down to a certain stroke, the upper part of the blow molded product 51 will enter the upper cavity 7 matched with it. At this time, the upper cylinder 4 stops running, and the upper module 6 remains in this position. When the lower cylinder 13 is started, the piston rod of the lower cylinder 13 will drive the lower module 15 to move upward through the lower fixed plate 14. When the lower module 15 moves upward, the lower left hinge head 27 and the lower right hinge head 30 move upward synchronously. When the lower left hinge head 27 moves upward, the left swing arm 28 When the lower right hinge head 30 moves upward, the right swing arm 31 will be stressed and swing, thereby pushing the upper right hinge head 32 to move right, realizing the synchronous movement of the right slide plate 24. Therefore, when the lower module 15 moves upward under the action of the lower cylinder 13, the left slide plate 23 and the right slide plate 24 are separated from each other, and the distance between the left slide plate 23 and the right slide plate 24 gradually increases. The upwardly moving lower module 15 just passes through the gap between the left slide plate 23 and the right slide plate 24 to approach the blow molded product 51, and finally the lower part of the blow molded product 51 enters the lower cavity 16 of the lower module 15.
[0035] The blowing hole 8 on the front side of the upper fixed plate 5 is not only connected with the upper cavity 7, but also as the upper part of the blow-molded product 51 is embedded in the upper cavity 7, the blowing hole 8 is opposite to the bottle mouth 5101 of the blow-molded product 51, and a matching air supply pipeline can be installed in the blowing hole 8 or a matching fan can be installed at the position of the recess 9 to directly supply gas to the blow-molded product through the bottle mouth 5101 of the blow-molded product 51, thereby achieving an air-cooling effect and effectively accelerating the cooling of the blow-molded product.
[0036] The water inlet hole 38 on the lower surface of the lower module 15 can be used to connect a water supply pipe, and the water inlet hole 38 on the lower surface of the lower module 15 can be used to connect a water outlet pipe. As the water supply pipe supplies water to the water cooling channel 17, the temperature of the lower module 15 itself will drop accordingly, thereby effectively cooling the lower part of the blow-molded product 51 embedded in the lower cavity 16, and the flowing water can effectively take away the heat transferred to the lower module 15 by the blow-molded product 51, further ensuring the cooling effect. In actual use, the water supply pump used to connect the water supply pipe and the water outlet end of the water outlet pipe are placed in the same water reservoir, thereby realizing the circulation of water flow, which can not only always maintain the circulation of water flow and ensure the water cooling effect, but also effectively save water resources.
[0037] From the above, it can be known that the utility model can achieve communication with the blow-molded product 51 through the blowing hole 8 on the upper module 6, so as to facilitate the active cooling of the blow-molded product 51 by using the flowing gas, and at the same time, the heat of the lower part of the blow-molded product 51 can be effectively taken away by the flowing water flow in the water-cooling channel 17 on the lower module 15. When the upper and lower parts of the blow-molded product 51 are cooled synchronously, the blow-molded product 51 exposed to the outside will also be affected by the cooling, thereby accelerating its own cooling, and finally achieving rapid cooling of the blow-molded product 51 as a whole, effectively ensuring the shaping efficiency of the blow-molded product 51.
[0038] When the blow molded product 51 is cooled and shaped, the upper module 6 moves up and resets under the action of the upper cylinder 4, and the lower module 15 moves down and resets under the action of the lower cylinder 13. As the lower module 15 moves down and resets through the gap between the left slide 23 and the right slide 24, the left slide 23 and the right slide 24 reset and begin to approach each other. When the lower module 15 completes its reset, the left slide 23 and the right slide 24 cover the top of the lower module 15. At this time, the clamping and transferring device can place the blow molded product that has completed cooling and shaping on the storage platform composed of the left slide 23 and the right slide 24, so that the unloading work of the blow molded product after cooling and shaping can be quickly carried out.
[0039] The lower fixing plate 14 is provided with symmetrical lower oblong holes 33 on the front and rear sides, and the lower surface of the lower module 15 is provided with lower screw holes 34 corresponding to the positions of the lower oblong holes 33. The screws only need to be passed upward through the lower oblong holes 33 and screwed into the lower screw holes 34. The heads of the screws are pressed on the lower surface of the lower fixing plate 14 to ensure the stability of the lower fixing plate 14. The existence of the lower oblong holes 33 makes it easy to adjust the position of the lower fixing plate 14 fixed on the lower module 15, thereby realizing the position adjustment of the lower module 15.
[0040] A plurality of evenly distributed lower guide rods 35 are provided on the outer edge of the lower surface of the lower fixed plate 14, and a plurality of lower guide holes 36 coaxial with the lower guide rods 35 are provided on the lower cylinder mounting plate 12. A matching lower guide sleeve 37 is provided in the lower guide hole 36, and the lower end of the lower guide rod 35 passes downward through the lower guide sleeve 37. The existence of the lower guide rod 35 can effectively ensure the stability of the lower module 15 during movement, thereby facilitating the accurate embedding of the lower part of the blow molded product 51 into the lower cavity 16 for cooling and shaping.
[0041] Several water-cooling channels 17 are interconnected, and the water-cooling channels 17 pass through the lower module. The ports of the water-cooling channels 17 are located on the outer wall of the lower module 15. The ports of the water-cooling channels 17 are threaded with matching plugs. This structural design facilitates the processing of the water-cooling channels 17. It is only necessary to seal the plugs in the ends of the water-cooling channels 17 to maintain the closure and sealing of the water-cooling channels 17.
[0042] A support frame 40 is provided directly below the lower fixing frame 10, and a plurality of evenly distributed adjusting rods 41 are provided on the lower surface of the lower fixing frame 10. An adjusting end 42 corresponding to the position of the adjusting rod 41 is provided on the upper edge of the support frame 40, and an adjusting hole 43 coaxial with the adjusting rod 41 is provided on the adjusting end 42. The lower end of the adjusting rod 41 passes downward through the adjusting hole 43, and an upper nut 44 fitted with the upper surface of the adjusting end 42 and a lower nut 45 fitted with the lower surface of the adjusting end 42 are screwed on the adjusting rod 41. The existence of the upper nut 44 and the lower nut 45 can tighten the adjusting rod 41. The position of the adjusting rod 41 can be moved by rotating the upper nut 44 and the lower nut 45, thereby effectively changing the height of the lower fixing frame 10, and finally effectively changing the initial vertical spacing between the upper module 6 and the lower module 15, so as to facilitate the cooling and shaping of the blow molded products 51 of different heights.
[0043] The upper fixing plate 5 is provided with upper oblong holes 46 symmetrical to each other on the left and right sides, and the upper module 6 is provided with upper screw holes 47 corresponding to the positions of the upper oblong holes 46 on the left and right sides of the upper surface. The screws only need to be passed downward through the upper oblong holes 46 and screwed into the upper screw holes 47 so that the heads of the screws are tightly pressed against the upper surface of the upper fixing plate 5. This can ensure the stability between the upper fixing plate 5 and the upper module 6. The existence of the upper oblong holes 46 makes it easy to effectively adjust the actual position of the upper module 6 by changing the position where the upper fixing plate 5 is fixed on the upper module 6.
[0044] The upper cylinder mounting plate 3 is provided with a plurality of evenly distributed upper guide holes 48, and the upper guide holes 48 are provided with matching upper guide sleeves 49. The upper surface of the upper fixed plate 5 is provided with an upper guide rod 50 coaxial with the upper guide sleeve 49, and the upper end of the upper guide rod 50 passes through the upper guide sleeve 49 upward. The existence of the upper guide rod 50 can effectively ensure the stability of the upper fixed plate 5 when driving the upper module 6 to move, thereby ensuring that the upper part of the blow-molded product 51 can be accurately embedded in the upper cavity 7 for cooling and shaping.
