The first driving member 211 drives the movable plate 212 to move in a direction close to the base 100, so that the first pressing block 213 abuts against the workpiece and can press the workpiece against the bottom wall of the cavity 110, and then the second driving member 221 drives the second pressing block 222 to move in a horizontal direction, so that the second pressing block 222 abuts against the workpiece and presses the workpiece against the side wall of the cavity 110, and multiple support assemblies 220 are arranged at intervals along the circumference of the movable plate 212, so that the multiple second pressing blocks 222 can position the workpiece in the cavity 110, so that the workpiece can fit against the wall surface of the cavity 110, reduce the deformation of the workpiece, and improve the processing accuracy of the workpiece. The fan 310 is set on the movable plate 212, and air is blown toward the base 100 through the fan 310 to accelerate the cooling of the workpiece, thereby reducing the deformation of the workpiece, and the airflow can enter the cavity 110 from the ventilation channel 120, which can increase the contact area between the airflow and the workpiece, so that the workpiece can be cooled evenly, the deformation is reduced, and the processing quality of the workpiece is improved.

[0029] It should be noted that there are multiple fans 310, which are arranged at intervals along the circumference of the movable plate 212, and the fans 310 are arranged at an angle so that the fans 310 can drive the airflow to smoothly enter the ventilation channel 120, thereby reducing the movement impact between the airflow and the inner wall of the ventilation channel 120, allowing the air to smoothly enter the ventilation channel 120, and then facilitating the airflow to absorb the heat of the workpiece and accelerate the cooling of the workpiece.

[0030] The first driving member 211 and the second driving member 221 may be air cylinders, oil cylinders, electric push rods, etc., which are not described in detail here.

[0031] It is understandable that, referring to Figure 1 , Figure 2 and Figure 4 The bottom wall of the cavity 110 is provided with a ventilation slot 130, and the ventilation slot 130 is connected with the ventilation channel 120. The bottom wall of the cavity 110 is provided with a ventilation slot 130, and the ventilation slot 130 is connected with the ventilation channel 120, so that the airflow can flow through the ventilation channel 120 and the ventilation slot 130 in sequence, so that the airflow can move smoothly, and the airflow can be discharged from the ventilation slot 130, so that the airflow is prevented from being blocked in the ventilation channel 120, and the movement resistance of the airflow is reduced, so that the airflow can flow smoothly, thereby increasing the contact area between the airflow and the workpiece, so as to accelerate the heat exchange between the airflow and the workpiece, speed up the cooling speed of the workpiece, reduce the deformation of the workpiece, and improve the processing quality of the workpiece.

[0032] It should be noted that one end of the ventilation groove 130 is connected to the ventilation channel 120, and the other end is connected to the outside of the base 100, so that the airflow can enter the ventilation groove 130 from the ventilation channel 120 and be discharged from the base 100, so that the airflow can move smoothly and increase the flow rate of the airflow, thereby facilitating the improvement of the flow speed of the airflow, thereby accelerating the heat dissipation of the workpiece, reducing the deformation of the workpiece, and improving the processing quality of the workpiece.

[0033] Specifically, refer to Figure 4 The number of ventilation slots 130 is set to be multiple, and the multiple ventilation slots 130 are arranged at intervals. By providing multiple ventilation slots 130, the flow rate of the airflow can be increased to accelerate the heat dissipation of the workpiece, improve the cooling efficiency of the workpiece, reduce the deformation of the workpiece, and improve the processing quality of the workpiece. In addition, the multiple ventilation slots 130 can disperse the airflow so that the flow of the airflow can be more uniform, so that the workpiece can be evenly cooled, the possibility of deformation of the workpiece is reduced, and the processing quality of the workpiece is improved.

[0034] It is understandable that, referring to Figure 1 and Figure 2 The heat dissipation mechanism 300 also includes a water cooling component 320, which includes a cooling pipe 321, a heat sink 322, a liquid storage tank 323 and a water pump 324. The cooling pipe 321 passes through the base 100 and the heat sink 322 in sequence, and the liquid storage tank 323 and the water pump 324 are connected to the cooling pipe 321.

The water pump 324 is connected to the cooling pipe 321. The water pump 324 can drive the coolant to circulate in the cooling pipe 321, so that the coolant can absorb the heat of the base 100, and then the coolant flows into the heat sink 322. The heat can be accelerated to be released into the air through the heat sink 322, so that the temperature of the base 100 can be reduced, and the workpiece can be accelerated to cool in the cavity 110, thereby reducing the deformation of the workpiece and improving the processing quality of the workpiece.

[0035] It is understandable that, referring to Figure 1 and Figure 4The positioning mechanism 200 further includes a guide assembly 230, which includes a guide column 231 and a slider 232.

The guide column 231 and the slider 232 cooperate to guide the movable plate 212 to move in the vertical direction, so that the movable plate 212 can move accurately, thereby improving the movement accuracy of the first pressing block 213, so that the workpiece can be stabilized in the cavity 110, and the reliability of the cooling and shaping device is improved.

[0036] It is understandable that, referring to Figure 1 The first pressing block 213 and the second pressing block 222 are both detachably connected with a buffer pad 240.

[0037] The buffer pad 240 may be a silicone component or a rubber component, which will not be described in detail here.

[0038] In addition, the buffer pad 240 can be detachably connected to the first pressing block 213 and the second pressing block 222 to facilitate the maintenance or replacement of the buffer pad 240, thereby extending the service life of the buffer pad 240 and improving the reliability of the cooling and shaping device.

[0039] It should be noted that the buffer pad 240 can be fixedly connected to the first pressing block 213 or the second pressing block 222 by bolts, buckles, etc., so as to facilitate the replacement of the buffer pad 240 and improve the convenience of maintenance.

The ejector rod 142 is fixedly connected to the movable end of the third driving member 141, and the ejector rod 142 is slidably connected to the bottom wall of the cavity 110. The ejector rod 142 is driven to rise by the third driving member 141 so that the ejector rod 142 can extend into the cavity 110, so that the workpiece can be ejected from the cavity 110 by the ejector rod 142, which is convenient for taking out the workpiece and improving the processing efficiency of the workpiece.

[0041] It should be noted that the third driving member 141 can be a pneumatic cylinder, an oil cylinder, an electric push rod, etc., which are not described in detail here.

[0042] Specifically, refer to Figures 2 to 4 The end of the push rod 142 is rotatably connected to a roller 143, and the roller 143 can abut against the workpiece. The roller 143 is rotatably connected to the end of the push rod 142, so that when the third driving member 141 drives the push rod 142 to rise, the roller 143 can abut against the workpiece, so that the roller 143 can roll on the workpiece, so that the workpiece can be easily taken out of the cavity 110, the push rod 142 can avoid scratching the workpiece, and the processing quality of the workpiece is improved.

[0043] It should be noted that the third driving member 141 drives the push rod 142 to rise so that the roller 143 can push the workpiece out of the cavity 110, and then the workpiece is taken away from one side of the base 100, so that the roller 143 can roll on the workpiece, thereby avoiding scratches on the workpiece and improving the unloading stability of the workpiece.
