DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1-4 As shown, a demoulding cooling mechanism of a vacuum forming machine includes a water tank 1, a water inlet 11 and a water outlet 12 are arranged on one side of the water tank 1, a water pump is arranged in the water tank 1, and the water pump is connected to an atomizing mechanism 2;

[0029] An inverted U-shaped frame 3 is fixedly connected to the upper side of the water tank 1, and a reciprocating screw 40 is assembled and connected in the middle of the U-shaped frame 3. A slide groove is opened in the U-shaped frame 3 just above the reciprocating screw 40, and a slider 41 is slidably connected in the slide groove of the U-shaped frame 3. Positioning rings 42 are fixedly connected to the front and rear sides of the slider 41; a sliding column 43 sliding in the thread groove of the reciprocating screw 40 is provided on the lower side of the slider 41.

[0030] The atomizing mechanism 2 includes a water pipe 21, the water pipe 21 is connected to a water pump, the water pipe 21 is connected to a threaded hose 22, and the threaded hose 22 is assembled and connected to an atomizing nozzle 23;

[0031] The atomizing mechanism 2 is provided with two groups, which are respectively located at the front and rear sides of the U-shaped frame 3. The atomizing nozzle 23 is assembled in the positioning ring 42, and the threaded hose 22 is assembled and connected to the upper side of the U-shaped frame 3 and arranged parallel to the upper side of the U-shaped frame 3.

[0032] In adopting the technical solution of this embodiment, it should be noted that the reciprocating screw 40 is connected to the motor assembly and is controlled to rotate by the motor. The atomizing mechanism 2 is used to atomize water. The inverted U-shaped frame 3 is used to assemble the reciprocating screw 40. The sliding column 43 reciprocates under the drive of the reciprocating screw 40. Since the sliding column 43 is in the thread groove and the slider 41 is in the slide groove, the slider 41 can only move in the horizontal direction. When the reciprocating screw 40 rotates, the sliding column 43 fixedly connected to the slider 41 can only It can move in the horizontal direction, so when the reciprocating screw 40 rotates, the sliding column 43 drives the positioning ring 42 to move back and forth, and the positioning ring 42 drives the atomizing nozzle 23 to move, so that the atomizing nozzle 23 moves back and forth to cool the product in all directions. When the atomizing nozzle 23 moves back and forth, the threaded hose 22 connected to the atomizing nozzle 23 is retracted according to the moving path of the atomizing nozzle 23. At the same time, the atomizing nozzle 23 is located on the front and rear sides of the U-shaped frame 3, so it can cool the product in a more all-round way.

[0033] Reference Figure 2 : A concave groove 13 is provided in the middle of the water tank 1, and a mold cooling component 5 is provided in the concave groove 13.

[0034] In this embodiment, the mold cooling assembly 5 cools the bottom of the mold.

[0035] Reference Figure 3 The mold cooling assembly 5 includes a cooling plate 51 and a telescopic cylinder 52. The telescopic cylinder 52 is assembled in the concave groove 13. The cooling plate 51 and the telescopic cylinder 52 are assembled and connected. The cooling plate 51 is located on the upper surface of the water tank 1.

[0036] In this embodiment, the telescopic cylinder 52 is used to move the cooling plate 51 up and down so that the cooling plate 51 is in close contact with the bottom of the mold to cool the mold. When the cooling plate 51 is located on the upper surface of the water tank 1, the cooling plate 51 is in contact with the water tank 1, and the water tank 1 cools the cooling plate 51.

[0037] Reference Figure 3 : The four sides of the cooling plate 51 are provided with downwardly inclined chamfers.

[0038] In this embodiment, the inclined chamfer allows the water above the cooling plate 51 to flow through the chamfer to the upper side of the water tank 1 .

[0039] Reference Figure 3 : A plurality of heat dissipation ribs 53 are fixedly connected to four sides of the cooling plate 51, and the plurality of heat dissipation ribs 53 are evenly arranged.

[0040] In this embodiment, the heat dissipation ribs 53 are used to dissipate heat from the cooling plate 51 .

[0041] Reference Figure 1: A shielding plate 14 is fixedly connected around the upper side of the water tank 1.

[0042] In this embodiment, the shielding plate 14 is used to shield the water mist. When the water mist condenses into water, the shielding plate 14 can shield the water.

[0043] Reference Figure 1 or Figure 3 : The left and right sides of the upper side of the water tank 1 are inclined downward, and a plurality of first water holes 15 are provided on both sides of the water tank 1.

[0044] In this embodiment, since the left and right sides of the upper side of the water tank 1 are inclined downward, water slides to the left and right sides of the water tank 1 under the action of gravity, and at the same time falls into the water tank through the first water hole 15, completing the reuse of water.

[0045] Reference Figure 3 The water tank 1 is provided with a plurality of second water holes 16 on both sides of the front and rear of the concave groove 13.

[0046] In this embodiment, the water generated by the atomizing mechanism 2 is sprayed out from the atomizing nozzle 23 to cool and shape the product. The condensed water falls into the concave groove 13 and then is discharged into the water tank 1 from the second water through hole 16.
