Description

Technical Field

[0001] The utility model relates to the field of casting coating drying, in particular to a casting coating drying device. Background Art

[0002] Foundry coatings are specialized refractory materials designed specifically for the casting process, used as a protective layer on the surface of molds or sand cores. These coatings typically exist in a colloidal state before application. After being applied to the mold or sand core, they must be dried to enhance the coating's strength and prevent porosity defects caused by water evaporation, thereby ensuring the quality of the final casting. This process requires efficient drying equipment.

[0003] However, the drying devices currently widely used in the foundry industry mostly utilize hot air dryers, which dry the mold by blowing hot air directly from a hot air outlet. While this drying method achieves a basic drying effect, it has significant drawbacks: due to the varying distances between different parts of the mold and the hot air outlet, heat is unevenly distributed across the mold, resulting in varying degrees of drying. This uneven drying not only affects the consistency of coating properties but can also cause some areas to prematurely cure or fail to fully dry, increasing the risk of defects such as cracking and flaking, reducing yield and product quality.

[0004] In view of this, it is necessary to improve the above defects.

[0005] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0008] A casting coating drying device, comprising:

[0009] A box body and a door, wherein the box body is open to the front, and the door has a handle and is hinged to one side of the opening;

[0010] The inner frame is fixedly connected to the inside of the box body, has a plurality of air holes, and forms a ventilation duct between the inner frame and the inner wall of the box body;

[0011] At least two heat sources are diagonally arranged in the air duct, each heat source includes a heating wire and a fan box, and a plurality of fans are arranged in the fan box;

[0012] A rotating frame, with its opening facing forward and disposed in the inner frame, is provided with a plurality of ventilation holes, and the rotating frame rotates within the inner frame;

[0013] The mold is arranged in the rotating frame.

[0014] As an improvement, an oblique angle is set at the diagonal position away from the heat source in the air duct.

[0015] As an improvement, a platform portion is provided in the middle of the frame surface of the rotating frame, and a water collecting portion is provided on the inner top wall of the inner frame. The water collecting portion narrows from top to bottom.

DETAILED DESCRIPTION

[0025] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0026] Please refer to the instruction manual Figures 1 to 4 The utility model discloses a casting coating drying device, specifically, a device for drying the mold and the casting coating as a whole after the casting coating is applied to the mold. The device mainly includes a box body 1, a box door 2, an inner frame 3, at least two heat sources, a rotating frame 7, and a mold 8, wherein the box body 1 is open to the front, and the box door 2 has a handle and is hinged to the open side; the inner frame 3 is fixedly connected to the interior of the box body 1, and is provided with a plurality of air holes, and a ventilation duct 4 is formed between the inner frame 3 and the inner wall of the box body 1; the heat sources are diagonally arranged in the duct 4, each heat source includes an electric heating wire 5 and a fan box 6, and the fan box 6 is provided with a plurality of fans. When in use, the electric heating wire 5 generates heat to heat the air nearby, and then the fan in the fan box 6 rotates to push the hot air into the duct 4, interacting with each other to form a circulation. In order to enhance this effect, the present invention also provides an oblique angle 9 at the diagonal position away from the heat source in the air duct 4. When the hot air hits the oblique angle 9, it will be folded into another vertical air duct 4 to achieve the effect of guiding the air. Moreover, since the density of hot air is less than that of cold air, the hot air will bring out the cold air in the box body 1 or the inner frame 3 through the air vents thereon during the circulation of the hot air in the air duct 4, and replenish the hot air, so that the hot air enters the interior of the inner frame 3 for drying.

[0027] At the same time, the rotating frame 7 is open to the front and is arranged in the inner frame 3. A number of air holes are provided on the rotating frame 7 so that hot air can enter the interior of the rotating frame 7. Moreover, by providing an additional grooved wheel structure, the rotating frame 7 can be driven to perform intermittent rotational motion inside the inner frame 3. The mold 8 is arranged in the rotating frame 7. Therefore, when the rotating frame 7 rotates, the mold 8 will be driven to rotate, thereby better drying.

[0028] In order to explain the specific working principle of the sheave structure, in a preferred embodiment of the present invention, please refer to the accompanying drawings. Figure 2 In the present invention, a rotating shaft 15 is fixedly connected to the rear end of the inner frame 3. The rotating shaft 15 passes through the housing 1 and is fixedly connected to a sheave 16. The sheave 16 is provided with several sets of corresponding grooves 17 and arcs 18. One of the arcs 18 is provided with a semi-circular disc 19 that fits therewith. A rotating rod 20 is fixedly connected to the semi-circular disc 19. The rotating rod 20 is provided with a dial head 21 that cooperates with the groove 17. The semi-circular disc 19 is driven by a motor 22. The motor 22 is arranged behind the semi-circular disc 19, and its output shaft is fixedly connected to the semi-circular disc 19. The bottom end of the motor 22 is fixedly connected to a motor base 23, which is fixedly connected to the rear end of the housing 1. Therefore, when the motor 22 is powered, its output shaft drives the semi-circular disc 19 to rotate, thereby driving the rotating rod 20 and the dial head 21 to rotate. When the dial head 21 runs into the groove 17 on the groove wheel 16, it contacts the side wall of the groove 17 and drives the groove wheel 16 to rotate. At this time, the dial head 21 continues to rotate until the groove wheel 16 rotates through one cycle and comes out from the other end. At this time, the dial head 21 contacts and abuts the groove 17, and the groove wheel 16 loses its thrust and stops rotating. This cycle is repeated to achieve intermittent rotation motion.

[0029] During the drying process, when the cold air contacts the inner frame 3, water droplets will condense. When these water droplets gather to a large enough size, they will fall down and land on the mold 8, affecting the finished product after drying. Therefore, in order to avoid this problem, the present invention further provides a platform portion 10 in the middle of the frame surface of the rotating frame 7, and a water collecting portion 11 is provided on the inner top wall of the inner frame 3. The water collecting portion 11 narrows from top to bottom. The cold air in the inner frame 3 falls on the water collecting portion 11 after condensation, falls along the edge of the water collecting portion 11, and finally falls on the platform portion 10, and falls as the rotating frame 7 rotates.

[0030] Finally, a collecting box 12 is provided under the rotating frame 7. Notches are provided on both sides of the collecting box 12, and a protrusion 13 is slidably connected thereto. The protrusion 13 is fixedly connected to the inner wall of the inner frame 3. A hand-picking groove 14 is provided at the front of the rotating frame 7. The collecting box 12 is used to collect the casting coating that falls from the mold 8. When the collection is full, it will be removed and poured out.

[0031] It should be noted that the electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of this disclosure omits the detailed description of known functions and known components. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment.

[0032] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
