Description

Technical Field

[0001] The utility model relates to the field of automated production, in particular to an automatic circulation cooling device outside a plastic part mold. Background Art

[0002] At present, the production of multi-color bottle caps on the market requires injection molding through at least two injection molding equipment. After the injection molding of the first color of the bottle cap is completed, it needs to be cooled before the injection molding of the second color. Generally, the bottle cap production is injection molding in large quantities. When cooling, the bottle caps need to be manually packed and transported to the warehouse for static cooling. After cooling for a period of time, they are transported out of the warehouse for encapsulation injection molding of the next color of the bottle cap. This has the following problems: 1. Manual packing is required for warehousing and outbound transportation, and turnover transportation wastes manpower, resulting in high overall production costs; 2. The injection molding interval of the two colors is long, the injection molding interval of the two colors is long, and the process continuity is poor, resulting in low overall production efficiency.

[0028] Example

[0029] Reference Figure 1-2 As shown, the utility model discloses an automatic circulation cooling device outside the mold of plastic parts, including a support frame 10, on which a cooling module 20 and a moving module 30 are installed; the moving module 30 drives the bottle cap 40 to move on the support frame 10, and the cooling module 20 cools the bottle cap 40 to achieve cooling of the injection-molded bottle cap 40.

[0030] Reference Figure 1-7 As shown, the moving module 30 includes at least two positioning jigs 301 and a cylinder assembly; in this embodiment, the positioning jigs 301 include 5, and the positioning jigs 301 include a tray 3011. Two positioning blocks 3012 are arranged on the tray 3011. The tray 3011 increases the contact area between the positioning jig 301 and the support frame. The bottle cap 40 is covered on the positioning block 3012, so that the bottle cap 40 is fixed on the positioning jig 301 while the outer surface of the bottle cap is in contact with the air with the maximum area, thereby improving the cold cutting efficiency.

[0031] Reference Figure 1-7As shown, the cylinder assembly includes two push cylinders 302 and two sliding cylinders 303. The sliding cylinder 303 pushes the positioning fixture 301 to move along the length direction of the support frame 10, and the push cylinder 302 pushes the positioning fixture 301 to move perpendicular to the length direction of the support frame 10. Specifically, the support frame 10 includes an upper support plate 101 and a lower support plate 102. The positioning fixture 301 is placed on the upper support plate 101. The upper support plate 101 is provided with a first guide hole 1011 and a second guide hole 1012. The second guide hole 1012 is arranged at one end of the first guide hole 1011. The width of the first guide hole 1011 and the second guide hole 1012 is smaller than the width of the positioning fixture 301. The pushing cylinder 302 and the sliding cylinder 303 are installed on the lower support plate 102. The piston rod of the sliding cylinder 303 is installed with a first push block, and the piston rod of the pushing cylinder 302 is installed with a second push block. The first push block protrudes from the first guide hole 1011, and the second push block protrudes from the second guide hole 1012. Specifically, when the first positioning jig 301 is placed on the first guide hole 1011, the pushing cylinder 302 on one side drives the second pushing block to push the positioning jig 301 to move, and then the second positioning jig 301 is placed on the first guide hole 1011, and the second pushing block drives the second positioning jig 301 to push the first positioning jig 301 to move to the second guide hole 1012, and the sliding cylinder 303 on one side is controlled to push the first positioning cylinder to move above the pushing cylinder 302 on the other side, and the pushing cylinder 302 on the other side pushes the positioning jig 301 to move toward the sliding cylinder 303 on the other side. In this way, five positioning jigs 301 are placed on the upper support plate 101, and the five positioning jigs 301 form a closed-loop circulation movement on the upper support plate 101 through the offset pushing cylinders 302 and the offset sliding cylinders 303 on both sides, and the moving positioning jig 301 drives the bottle cap 40 to move to achieve the effect of cold cutting. Furthermore, a plurality of sensors 1013 are installed on one side of the upper support plate 101 along the length direction. When placed at the initial position of the upper support plate 101, the sensor 1013 senses the positioning jig 301 and controls the pushing cylinder 302 to push the positioning jig 301 to move. The sensor 1013 is used to sense the positioning jig 301 and control the corresponding pushing cylinder 302 and sliding cylinder 303 to move the positioning jig 301.

[0032] Reference Figure 1-7 As shown, the cooling module 20 includes a cooling tube 201 disposed inside the support frame 10, and the openings at both ends of the cooling tube 201 are placed on the side of the support frame. In this embodiment, the cooling tube 201 includes two, which are respectively disposed at both ends of the upper support plate 101, so that the positioning fixture 301 that has completed a cycle can pass through the cooling tube 201 twice, allowing the bottle cap 40 on the positioning fixture 301 to cool quickly and enter the next color of injection molding. Compared with traditional cooling, the utility model eliminates the need for collection, packaging, and transportation, saves manpower and time, and improves injection molding efficiency.

[0033] Reference Figure 1-7 As shown, a lifting cylinder 1021 is installed in the middle of the lower support plate 102, and a through hole is opened in the middle of the upper support plate 101. The piston rod of the lifting cylinder 1021 passes through the through hole upward to set a pressing plate 1022. When the positioning fixture 301 needs to be placed, the lifting cylinder 1021 is controlled to push the pressing plate 1022 upward. After the positioning fixture 301 is placed, the pressing plate 1022 is pressed down. The guide channel formed around the pressing plate 1022 and the upper support plate 101 guides the movement of the positioning fixture 301.
