Example

[0029] See also Figure 1-Figure 5 The figure shows a denture casting machine, including a base 1 and a casting head 2, a casting cylinder 3 and an auxiliary structure 9. A fixed cavity 4 is provided on the base 1, and the casting cylinder 3 is fixed on the top of the fixed cavity 4. A module 5 is provided in the casting cylinder 3, and a mounting cylinder 6 is provided in the fixed cavity 4. A cooling pipe 7 filled with coolant is spirally provided in the mounting cylinder 6. A cooling pump 8 is fixed at the bottom of the mounting cylinder 6, and both ends of the cooling pipe 7 are fixedly connected to the inlet and outlet of the cooling pump 8. The auxiliary structure 9 is located in the mounting cylinder 6 and is used to improve the flow of air in the mounting cylinder 6.

[0030] The auxiliary structure 9 includes a fan 10, a motor 11 is fixed at the bottom of the mounting tube 6, the output end of the motor 11 is fixed to the fan 10, the fan 10 is rotatably connected to the inner bottom of the mounting tube 6, a first through hole 12 is provided at the bottom of the mounting tube 6, and a second through hole 13 communicating with the outside is provided on the side of the fixed cavity 4.

[0031] A heating cylinder 14 is fixed at the bottom of the casting head 2, an upper pressure plate 15 is arranged inside the heating cylinder 14, an electric hydraulic rod 16 is fixed on the upper pressure plate 15, the electric hydraulic rod 16 is fixed in the casting head 2, a fixed cylinder 17 is fixed in the casting cylinder 3, a lower pressure plate 18 for supporting the module 5 is fixed in the fixed cylinder 17, and ventilation holes 19 are arranged on the outside of the fixed cylinder 17 and the casting cylinder 3 to facilitate heating or cooling of the module 5.

[0032] A hydraulic cylinder 20 is provided on the casting head 2, and the bottom of the hydraulic cylinder 20 is fixed to the base 1. A connecting rod 21 is fixed to the bottom of the casting head 2. The connecting rod 21 passes through the base 1 and is provided with a connecting plate 22. A telescopic rod 23 is fixed to the bottom of the mounting tube 6. The end of the telescopic rod 23 away from the mounting tube 6 is fixed to the connecting plate 22. The connecting plate 22 is slidably connected to the side opening of the fixed cavity 4, so that the mounting tube 6 can move with the movement of the casting head 2. When the heating tube 14 wraps around the fixed tube 17, the mounting tube 6 is located at the bottom of the casting tube 3. When the heating tube 14 rises to the initial position driven by the casting head 2, it drives the mounting tube 6 to wrap around the casting tube 3 from the bottom for cooling operation.

[0033] The outer diameter of the casting tube 3 is smaller than the size of the space inside the spiral cooling tube 7 , so that the wind blown by the fan 10 can pass through the surface of the cooling tube 7 and blow into the casting tube 3 .

[0034] The fixing tube 17 is slidably engaged with the interior of the heating tube 14 to improve the heating effect.

[0035] The inner depth of the installation tube 6 is greater than the height of the casting tube 3, so that the cooling tube 7 can more completely wrap the casting tube 3 and increase the travel distance of the cold air blown by the fan 10.

[0036] Working principle: The module 5 loaded with raw materials is placed on the lower pressure plate 18 in the fixed cylinder 17, and then the casting head 2 is driven down by the hydraulic cylinder 20, and the heating cylinder 14 is embedded in the casting cylinder 3. The heating cylinder 14 wraps the fixed cylinder 17, and then the upper pressure plate 15 is driven down by the electric hydraulic rod 16 to fix the upper surface of the module 5, and then the heating cylinder 14 is used to heat it. The hot air enters the fixed cylinder 17 through the vent 19 to heat the module 5. After heating, the casting head 2 is lifted to make the heating cylinder 14 return to the initial position, and then the fan 10 is driven to rotate by the motor 11, and the cooling pump 8 drives the coolant in the cooling pipe 7 to flow, so that the cold air in the installation cylinder 6 flows upward and enters the fixed cylinder 17 through the vent 19 to cool the module 5, thereby accelerating the molding speed of the raw materials in the module 5;

[0037] When the casting head 2 descends, the connecting plate 22 and the telescopic rod 23 are driven downward by the connecting rod 21 until the mounting tube 6 is driven downward. When the heating tube 14 is against the inner bottom of the casting tube 3, the fixing tube 17 is below the casting tube 3. When the casting head 2 returns to the initial position, the mounting tube 6 is pushed back to the top of the fixing cavity 4 to wrap the casting tube 3, so that the heating and cooling operations do not interfere with each other. Example

[0038] See also Figure 4 This embodiment further illustrates Example 1: a limit plate 24 is fixed in the fixed cavity 4, the telescopic rod 23 passes through the limit plate 24 and is slidably connected to the limit plate 24, a limit ring 26 is fixed in the fixed cavity 4, a fixing ring 27 is fixed on the outside of the mounting tube 6, and the mounting tube 6 slides in the fixed cavity 4 through the fixing ring 27 to limit the movement range of the mounting tube 6.

[0039] Implementation principle: the limit plate 24 limits the downward movement range of the installation cylinder 6, and the limit ring 26 limits the upward movement range of the installation cylinder 6, thereby preventing the installation cylinder 6 from excessively moving and affecting the heating operation and the cooling operation. Example

[0040] See also Figure 3 and Figure 5 This embodiment further illustrates Example 1: both the upper pressing plate 15 and the lower pressing plate 18 are provided with air holes 25 .

[0041] Implementation principle: The cold air and the hot air can be brought into contact with the upper and lower surfaces of the module 5 to improve the cooling or heating effect.
