They can freely change their composition and shape. They are composed of synthetic resins and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. In the production process of plastic products, cooling devices are required.

[0031] Specifically, a latch 13 is welded and fixed to the right end of the mounting plate 12 , and the right end of the latch 13 passes through the right end of the turntable 21 and is plugged into and matched with the inner wall of the slot 11 corresponding to its position, so as to limit the rotation of the turntable 21 .

[0032] It should be supplemented that a cooling box 14 is fixedly connected to the right side surface of the outer shell 1 by bolts, and a ventilation pipe 15 is fixedly connected to the left side surface of the inner wall of the cooling box 14 near the upper part by bolts, and the left end of the ventilation pipe 15 passes through the left end of the cooling box 14 and the right end of the outer shell 1 in sequence and passes into the inner cavity of the outer shell 1, so as to introduce the internal air of the cooling box 14 into the outer shell 1.

[0033] Specifically, an air pump 16 is fixedly connected to the left side surface of the inner wall of the cooling box 14 near the bottom by bolts. The air pump 16 sucks the air in the outer shell 1 through the air inlet pipe 17 and introduces the air into the cooling box 14 through the air outlet pipe 18.

The air outlet of the air pump 16 is connected to the air outlet pipe 18.

[0034] As a preferred embodiment of the present invention, a turning mechanism 2 is provided in the housing 1. The turning mechanism 2 includes a turntable 21. The right end of the turntable 21 is rotatably connected to the left end of the housing 1 via a bearing to drive the rotating rod 22 to rotate.

[0035] Specifically, the right end of the rotating disk 21 is fixedly connected to the rotating rod 22 by bolts, which is used to drive the mounting seat 23 to rotate. The right end of the rotating rod 22 passes through the left end of the housing 1 and is fixedly connected to the mounting seat 23 by bolts.

[0036] Specifically, a rotating motor 24 is fixedly connected to the top of the inner wall of the mounting seat 23 by bolts to drive the bidirectional threaded rod 26 to rotate, and a limiting plate 25 is fixedly connected to the bottom of the rotating motor 24 by bolts to limit the position of the movable plate 27 near the top.

[0037] Specifically, the output shaft of the rotating motor 24 is coaxially connected to a bidirectional threaded rod 26, the bottom end of the bidirectional threaded rod 26 passes through the bottom of the limiting plate 25 and fits against the bottom of the inner wall of the mounting seat 23, and the bidirectional threaded rod 26 is symmetrically provided with threads with opposite thread directions near the upper and lower sides, so that when the bidirectional threaded rod 26 rotates, the two movable plates 27 move in opposite directions.

[0038] Specifically, the two-way threaded rod 26 is symmetrically threaded with a movable plate 27 near the upper and lower sides for driving the tray 28 to move. The right end of the movable plate 27 is fixedly connected to the tray 28 by bolts for placing plastic products.

[0039] Specifically, a plurality of ventilation holes 29 are provided on the top of the tray 28 . The ventilation holes 29 are evenly arranged at equal intervals and are used to guide the air in the housing 1 into the inner cavity of the tray 28 .

[0040] Furthermore, a cooling mechanism 3 is provided in the cooling box 14, and the cooling mechanism 3 includes a cooling block 31. The side surface of the cooling block 31 is in contact with the side surface of the inner wall of the cooling box 14. A mounting groove 32 is provided at the center of the top of the cooling block 31. A plurality of ventilation grooves 33 are symmetrically provided at positions near the left and right sides of the top of the cooling block 31. The ventilation grooves 33 are arranged at uniform and equal intervals, so that the surface area of ​​the cooling block 31 in contact with the air inside the cooling box 14 is increased.

[0041] Specifically, a water pump 34 is fixedly connected to the bottom of the inner wall of the installation groove 32 by bolts, a water outlet of the water pump 34 is connected to a water outlet pipe 35, and one end of the water outlet pipe 35 is connected to a heat exchanger 36 for heat exchange.

[0042] Specifically, the water outlet of the heat exchanger 36 is connected to a connecting pipe 37 , one end of which is connected to a refrigerator 38 for cooling; the water outlet of the refrigerator 38 is connected to a return pipe 39 , one end of which is connected to the water inlet of the water pump 34 .

[0043] It is worth mentioning that the structures and working principles of the heat exchanger 36 and the refrigerator 38 involved in this embodiment are well known to those skilled in the art and will not be elaborated herein.

[0044] During specific use, the user first opens the door panel at the front end of the housing 1, and then turns on the rotating motor 24. The rotating motor 24 drives the bidirectional threaded rod 26 to rotate, thereby driving the two moving plates 27 to move away from the mounting seat 23, thereby driving the two trays 28 to move away from the mounting seat 23;

[0045] When the top of the movable plate 27 near the top is in contact with the bottom of the limiting plate 25, the rotating motor 24 is turned off, the plastic product to be cooled is placed on the bottom of the inner wall of the tray 28 near the bottom, and the door panel at the front end of the housing 1 is closed;

[0046] Turn on the water pump 34, the heat exchanger 36 and the refrigerator 38. The water pump 34 delivers water to the heat exchanger 36 through the outlet pipe 35 for heat exchange. The water after heat exchange is introduced into the refrigerator 38 through the connecting pipe 37 by the heat exchanger 36 for cooling. The water after cooling is guided back to the water pump 34 through the return pipe 39. In this process, the cold water circulation inside the installation tank 32 reduces the temperature inside the installation tank 32, thereby reducing the surface temperature of the cooling block 31.

[0047] The air pump 16 is turned on. The air pump 16 sucks the air in the housing 1 through the air inlet pipe 17 and sends the air into the cooling box 14 through the air outlet pipe 18. The air near the bottom of the cooling box 14 moves upward. When it contacts the surface of the cooling block 31, the air temperature decreases. The air with the reduced temperature is introduced into the housing 1 by the vent pipe 15, so that the temperature inside the housing 1 decreases. The air with the reduced temperature in the housing 1 enters the inner cavity of the two trays 28 from the vent hole 29, so that the temperature of the plastic product decreases.

[0048] When the plastic product needs to be turned over, the rotating motor 24 is reversed, and the rotating motor 24 drives the bidirectional threaded rod 26 to rotate, thereby driving the two moving plates 27 to move toward the mounting seat 23, thereby driving the two trays 28 to move toward the mounting seat 23;

[0049] Until the top of the inner wall of the tray 28 near the top fits with the top of the plastic product, turn off the rotating motor 24. At this time, the plastic product is clamped and fixed by the two trays 28. Move the mounting plate 12 to the left, thereby driving the latch 13 to move to the left, until the latch 13 is no longer plugged into the inner wall of the slot 11 corresponding to its position, rotate the turntable 21, thereby driving the rotating rod 22 to rotate, thereby driving the mounting seat 23 to rotate, thereby driving the rotating motor 24 and the limiting plate 25 to rotate, thereby driving the bidirectional threaded rod 26 to rotate, thereby driving the moving plate 27 to rotate, thereby driving the two trays 28 to rotate, and thereby driving the plastic product to rotate;

[0050] When the turntable 21 is rotated 180°, the rotation of the turntable 21 is stopped, and the mounting plate 12 is driven to move to the right, thereby driving the latch 13 to move to the right, until the latch 13 is plugged into the inner wall of the slot 11 corresponding to its position, and the turntable 21 can no longer rotate, and the rotating motor 24 is reversed. The rotating motor 24 drives the bidirectional threaded rod 26 to rotate, thereby driving the two moving plates 27 to move away from the mounting seat 23, thereby driving the two trays 28 to move away from the mounting seat 23, until the top of the moving plate 27 near the top is in contact with the bottom of the limit plate 25, and then the rotating motor 24 can be turned off.

[0051] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
