On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0021] The sand mold surface coating drying device of the utility model embodiment is described below in conjunction with the accompanying drawings.

[0022] like Figures 1 to 4 As shown, the sand mold surface coating drying device of the embodiment of the utility model includes a support component 1, a plurality of heat radiation components 2, a controller 3 and a temperature sensor 4.

[0023] The support assembly 1 is placed above the sand box 5 , and a plurality of heat radiation assemblies 2 are respectively connected to the support assembly 1 , and the heat radiation assemblies 2 are arranged at the opening of the sand box 5 .

[0025] Furthermore, the heat radiation assembly 2 described in the above embodiment can emit infrared rays to the sand mold inside the sand box 5 to make the molecules on the surface of the sand mold vibrate, thereby increasing its temperature to achieve the purpose of drying it.

[0026] The controller 3 is disposed on the supporting component 1 , the temperature sensor 4 is disposed on one of the heat radiation components 2 , and the controller 3 is connected to the temperature sensor 4 and the heat radiation component 2 , respectively.

[0027] It should be noted that the controller 3 described in this embodiment can be electrically connected to the temperature sensor 4 and the heat radiation component 2 respectively by wired or wireless means. The temperature sensor 4 can timely detect the air temperature around the heat radiation component 2 and transmit the temperature data to the controller 3. The controller 3 analyzes the temperature data and controls the heat radiation component 2 to be turned on or off to achieve control of the drying temperature.

[0028] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the support assembly 1 may include a support frame 10, a plurality of support frames 11 and a plurality of support rods 12, wherein the support frame 10 is placed above the sand box 5, and the controller 3 is installed on the side wall of the support frame 10, the plurality of support frames 11 are evenly distributed on the upper surface of the support frame 10, and the plurality of support rods 12 are respectively arranged at right angles to the support frame 10, and the support rods 12 are threadedly connected to the support frame 10.

[0029] It should be noted that the support frame 11 described in this embodiment is a U-shaped structure, and the support frame 10 and the support frame 11 can be fixed by welding to improve their stability.

[0030] Furthermore, the support rod 12 is provided with an external thread, and the support frame 10 is penetrated with a threaded hole (not shown in the figure). The support rod 12 is penetrated through the threaded hole, and the support frame 10 can be suspended above the sand box 5 through the support rod 12.

[0031] Furthermore, if Figure 3 As shown, a plurality of legs 6 are oppositely disposed on both sides of the support frame 10 , and universal wheels 7 are disposed at the bottom of the legs 6 .

[0032] It should be noted that the multiple legs 6 described in this embodiment form two rows, and the legs 6 are L-shaped structures, and the universal wheels 7 have a braking function. By installing the universal wheels 7, the entire drying device can be easily moved, making it more convenient to use.

[0033] Furthermore, the distance between the two rows of legs 6 described in the above embodiment is greater than the width of the sand box 5, and when the universal wheel 7 is on the ground, the support frame 10 is placed above the sand box 5, so that the entire drying device can pass across the sand box 5.

[0034] In one embodiment of the present invention, Figure 4 As shown, the heat radiation assembly 2 may include a protective cover 20, a mounting plate 21 and a plurality of infrared lamp tubes 22, wherein the protective cover 20 is mounted on a support frame 11, and an opening of the protective cover 20 and an opening of the sand box 5 are arranged opposite to each other, the mounting plate 21 is arranged inside the protective cover 20, the temperature sensor 4 is embedded and installed on a side of the mounting plate 21 adjacent to the sand box 5, and a plurality of infrared lamp tubes 22 are evenly distributed on the mounting plate 21.

[0035] It should be noted that the protective cover 20 described in this embodiment can be installed on the support frame 11 by bolts or screws. The protective cover 20 can protect the infrared lamp tube 22 to prevent the infrared lamp tube 22 from being broken, thereby extending the service life of the infrared lamp tube 22.

[0036] Furthermore, the infrared lamp tube 22 is electrically connected to the controller 3 , and the infrared lamp tube 22 can be controlled to be turned on or off by the controller 3 .

[0037] Specifically, when drying the paint on the surface of the sand mold, first, the relevant personnel puts the sand box 5 upright (the opening of the sand box 5 is placed upwards), and then the relevant personnel moves the entire drying device to the position of the sand box 5, and places the support frame 10 directly above the sand box 5, and then the support rod 12 can be rotated to make the support rod 12 contact with the upper surface of the sand box 5. When there is no universal wheel 7, the support frame 10 can be suspended above the sand box 5 through the support rod 12.

[0038] Then, relevant personnel can control the infrared lamp 22 to turn on through the controller 3. The infrared lamp 22 can emit infrared rays to the sand mold inside the sand box 5 to increase the temperature of the sand mold, thereby achieving the purpose of drying the paint on the surface of the sand mold. At the same time, the temperature sensor 4 can timely detect the surrounding ambient temperature and transmit the temperature data to the controller 3. The controller 3 analyzes the temperature data. If the temperature data is greater than the temperature threshold (the temperature threshold can be set according to the specific situation and output to the controller 3 in advance), the controller 3 controls the infrared lamp 22 to turn off and use the waste heat of the air to perform secondary drying on the sand mold, thereby saving energy and improving the drying efficiency of the sand mold. At the same time, it can also avoid the impact of excessive temperature on the quality of the molding sand. Furthermore, because the entire drying device is movable, when the drying device is in an idle state, it can be moved out of the factory building, so that it will not occupy the factory building space, thereby improving the utilization rate of the factory building.
