[0016] In order to more clearly illustrate the technical solutions of the present utility model, the present utility model will be further described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the present utility model. For those of ordinary skill in the art, without creative efforts, other embodiments obtained based on this drawing and embodiment all fall within the protection scope of the present utility model.

[0017] According to Figures 1-4 As shown, a heat energy supply baking room for casting molding sand includes a housing 1. Heat sinks 2 are fixedly installed on the inner walls of the front and rear sides of the housing 1. A water pump 3 is fixedly installed on the top of the housing 1. The water inlet end of the water pump 3 is connected to the water outlet ends of the two heat sinks 2 through a water pipe. On one side of the top of the housing 1 away from the water pump 3, a water inlet pipe 4 is fixedly installed. The water inlet pipe 4 is connected to the water inlet ends of the two heat sinks 2. Since the water temperature at the water outlet end of the heat sink 2 is lower than that at the water inlet end, the service life of the water pump 3 is prevented from being affected by excessive water temperature.

[0018] In this embodiment, a number of fans 5 are also installed on the front and rear side walls of the housing 1. The number of fans 5 is located between the heat sink 2 and the side wall of the housing 1. The air circulation inside the housing 1 is improved through the fans 5, and at the same time, hot air is blown onto the workpiece to improve the drying efficiency of the paint surface.

[0019] In this embodiment, a base 6 is fixedly installed at the bottom of the housing 1. An electric heating plate 7 is fixedly installed inside the base 6. The top wall of the base 6 is a mesh structure. When the temperature inside the housing 1 is lower than the set drying temperature, the electric heating plate 7 is activated to assist in heating through the electric heating plate 7.

[0020] In this embodiment, feeding ports 8 are formed in the left and right side walls of the housing 1. A first conveying guide rail 9 is fixedly installed in the middle of the top end of the feeding port 8. Workpieces are successively hoisted onto the first conveying guide rail 9. The slings of each group of workpieces are connected to each other by chains. The chains are pulled by a driving device to make the workpieces slowly move along the first conveying guide rail 9 inside the housing 1.

[0021] In this embodiment, a number of fixing frames 10 are provided at the rear side of the housing 1. A second conveying guide rail 11 is installed on the fixing frame 10. The second conveying guide rail 11 and the first conveying guide rail 9 are connected to each other by a U-shaped guide rail 12. The workpieces move to the second conveying guide rail 11 after passing through the inside of the housing 1, so as to facilitate the staff to transfer the workpieces.

[0022] When the present utility model is in use, the water pump 3 is connected to the water inlet end of a heat exchanger (not shown in the figure), and the water inlet pipe 4 is connected to the water outlet end of the heat exchanger. The high-temperature molding sand is cooled in the heat exchanger. The hot water used for cooling the molding sand is conveyed into the heat sink 2 by the water pump 3. The housing 1 is heated by the heat sink 2, so as to reduce the operation cost and energy consumption at the same time, which is beneficial to environmental protection. The workpieces enter the housing 1 along the first conveying guide rail 9. The fan 5 blows hot air onto the surfaces of the workpieces to quickly dry the paint. After the paint is dried, the workpieces move to the second conveying guide rail 11 via the U-shaped guide rail 12, so as to facilitate the staff to transfer the workpieces.

[0023] The above embodiments are only exemplary embodiments of the present utility model and are not used to limit the present utility model. The protection scope of the present utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present utility model within the essence and protection scope of the present utility model, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present utility model.
