Description

Technical Field

[0001] The utility model relates to the technical field of wax mold drying, in particular to a temperature-controlled drying device for precision casting wax molds. Background Technique

[0002] In precision casting, wax molds are a key process material used to manufacture precise molds for metal castings. Wax mold casting is a method of investment casting, and its process includes steps such as manufacturing wax molds, assembling wax molds, sintering, pouring, and post-treatment. During the manufacturing process of wax molds, drying is a very crucial step because the wax molds must be thoroughly dried before casting to avoid mold bursting due to water vapor during the sintering process or affecting the flow of metal during the pouring process.

[0003] Currently, the existing temperature-controlled drying devices for wax molds on the market, when in use, dry by condensation, and some condensed moisture will still remain inside the device, resulting in insufficient drying. Content of the Utility Model

[0004] The purpose of the utility model is to provide a temperature-controlled drying device for precision casting wax molds to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A drying box, a water tank is arranged at the bottom end of the drying box, a dehumidification mechanism is arranged in the middle of the inner side of the water tank, and a condensation mechanism is arranged above the inside of the water tank;

[0008] The water tank is communicated with the outside of the drying box through an air duct, and a wind guiding mechanism is arranged below the inside of the drying box.

[0009] Preferably, the dehumidification mechanism includes a frame, the frame is fixedly installed in the middle of the inner side of the water tank, electric push rods are arranged inside both sides of the frame, clamping plates are arranged at the output shaft ends of the two electric push rods, and a sponge is movably installed in the middle of the frame;

[0010] Preferably, a plurality of through holes are arranged at the upper and lower ends in the middle of the frame, and a drain port is communicated with the outside of the bottom end on the left side of the water tank;

[0011] Preferably, the condensation mechanism includes a cold water pipe, the cold water pipe is arranged above the inside of the water tank, the upper ends on both sides of the water tank are respectively communicated with a water inlet and a water outlet, and both ends of the cold water pipe are respectively connected to the water inlet and the water outlet;

[0012] Preferably, the air guiding mechanism includes an air duct which is arranged below the interior of the drying box. The air duct is communicated with the water tank. A fan is arranged above the interior of the air duct, and a demisting plate is arranged below the interior of the air duct.

[0013] Preferably, a box door is movably installed on the front of the drying box, and a plurality of perforated trays are sequentially arranged in the drying box from top to bottom.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] For the temperature-controlled drying equipment for precision casting wax molds, through the coordinated use of the cold water pipe, sponge, demisting plate, fan and air duct, during drying, the fan controls the air inside the drying box and the water tank to circulate through the air duct, cooling and drying the wax molds. And since the cold air is blown from the bottom, the moisture in the air enters the air duct from the upper end of the drying box, so there will be no moisture backflow. Moreover, after the moisture enters the water tank, it is first adsorbed and dehumidified by the sponge once, then condensed and dehumidified by the cold water pipe twice, and finally dehumidified three times by the demisting plate before being sent into the drying box, which can improve the drying degree.

[0016] For the temperature-controlled drying equipment for precision casting wax molds, through the coordinated use of the water tank, sponge, electric push rod, clamping plate and drain port, when the wax mold is taken out after processing, then start the electric push rod. The electric push rod controls the clamping plate to push forward, squeezing out the water absorbed by the sponge in the middle of the frame, and then flowing into the lower part of the interior of the water tank, and then flowing back to the cold water supply tank through the drain port for use, which can reduce the waste of water resources.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figures 1-5 shown, a technical solution provided by the present invention:

[0025] A temperature-controlled drying device for precision casting wax molds, including a drying oven 1. A water tank 2 is provided at the bottom end of the drying oven 1. A dehumidification mechanism is provided in the middle of the inner side of the water tank 2. The dehumidification mechanism includes a frame 4. The frame 4 is fixedly installed in the middle of the inner side of the water tank 2. Electric push rods 5 are provided inside both sides of the frame 4. Clamping plates 6 are provided at the output shaft ends of the two electric push rods 5. A sponge 7 is movably installed in the middle of the frame 4. A plurality of through holes are provided at the upper and lower ends of the middle of the frame 4. A drain outlet 16 is communicated with the outside of the left bottom end of the water tank 2. A box door 14 is movably installed on the front surface of the drying oven 1. A plurality of perforated trays 15 are sequentially arranged from top to bottom inside the drying oven 1. A condensation mechanism is provided above the inside of the water tank 2. The condensation mechanism includes a cold water pipe 8. The cold water pipe 8 is provided above the inside of the water tank 2. The upper ends of both sides of the water tank 2 are respectively communicated with a water inlet 9 and a water outlet 10. Both ends of the cold water pipe 8 are respectively connected to the water inlet 9 and the water outlet 10;

[0026] In this embodiment, during drying, the fan 12 controls the air inside the drying oven 1 and the water tank 2 to circulate through the air duct 3, cooling and drying the wax mold. And because the cold air is blown from the bottom, the moisture in the air enters the air duct 3 from the upper end of the drying oven 1, so moisture backflow will not occur. Moreover, after the moisture enters the inside of the water tank 2, it is first adsorbed and dehumidified by the sponge 7 once, then condensed and dehumidified by the cold water pipe 8 twice, and finally dehumidified three times by the demisting plate 13 and then sent into the drying oven 1, which can improve the drying degree.

[0027] As Figure 1 and Figure 4As shown in the figure, a water tank 2 is connected to the outside of a drying oven 1 through an air duct 3. A wind guiding mechanism is arranged below the interior of the drying oven 1. The wind guiding mechanism includes a wind duct 11. The wind duct 11 is opened below the interior of the drying oven 1 and is connected to the water tank 2. A fan 12 is arranged above the interior of the wind duct 11, and a demisting plate 13 is arranged below the interior of the wind duct 11;

[0028] In this embodiment, after the wax mold is taken out after being processed, the electric push rod 5 is started. The electric push rod 5 controls the front push of the clamping plate 6 to squeeze out the water absorbed in the sponge 7 in the middle of the frame 4, and then flows into the lower part inside the water tank 2, and then flows back to the cold water supply tank through the drain port 16 for use, which can reduce the waste of water resources.

[0029] Working principle: During drying, the wax mold after precision casting is placed on the perforated tray 15 inside the drying oven 1, and then the external circulation pump is started. The circulation pump pumps the cooling water from the water inlet 9, and the cooling water flows along the cold water pipe 8 to the water outlet 10, and then flows back to the external cold water supply tank. During the flow of the cold water, the fan 12 is started. The fan 12 controls the air inside the drying oven 1 and the water tank 2 to circulate through the air duct 3, so as to cool and dry the wax mold. And because the cold air is blown from below, the moisture in the air enters the air duct 3 from the upper end of the drying oven 1, so moisture backflow will not be caused. Moreover, after the moisture enters the water tank 2, it is first adsorbed and dehumidified by the sponge 7 once, then condensed and dehumidified by the cold water pipe 8 twice, and finally dehumidified three times by the demisting plate 13 and then sent into the drying oven 1; the water absorbed by the sponge 7 can be recycled. After the wax mold is taken out after being processed, the electric push rod 5 is started. The electric push rod 5 controls the front push of the clamping plate 6 to squeeze out the water absorbed in the sponge 7 in the middle of the frame 4, and then flows into the lower part inside the water tank 2, and then flows back to the cold water supply tank through the drain port 16 for use.
