In a broad sense, gravity casting includes sand casting, metal mold casting, investment casting, lost foam casting, mud mold casting, etc. In a narrow sense, gravity casting mainly refers to metal mold casting. During the gravity casting process, the casting mold needs to be heated so that the mold has a certain temperature to prevent the metal liquid from solidifying instantly due to the low mold temperature during pouring. This process needs to be assisted by a mold heating device.

[0003] However, when the existing mold heating device is heating the mold, the mold is usually in close contact with the device. The heated mold has a high temperature and is not easy to take out. The removal is difficult and the mold is likely to fall off during the removal process. At the same time, the existing mold heating device mainly heats the bottom of the mold, which easily causes uneven heating of the mold, which has a certain negative impact on gravity casting.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1-4 A double-station gravity casting mold heating device is shown, comprising a box body 1, a heating component is arranged inside the box body 1, the heating component is adapted to the box body 1, both ends of the top outer wall of the box body 1 are provided with fixing components, the fixing components are adapted to the heating component, the fixing components comprise mounting grooves opened at both ends of the top outer wall of the box body 1, a support plate 5 is installed on the inner wall of the mounting groove, a support column 6 is rotatably installed on the top outer wall of the support plate 5, a mounting plate 7 is welded on the top of the support column 6, a threaded rod 8 is rotatably installed on the top of the mounting plate 7 through a thread, a fixing plate 9 is rotatably installed on the end of the threaded rod 8, the fixing plate 9 is adapted to the support plate 5, support grooves 11 are opened on both sides of the box body 1, an electric telescopic rod 12 is installed on the inner wall of the bottom of the support groove 11, and the end of the electric telescopic rod 12 is connected to the bottom outer wall of the support plate 5.

[0023] By means of the above structure: when working, the mold to be heated is placed in the heating assembly inside the box body 1, most of the mold enters the box body 1, and the edge of the mold is placed on the support plate 5. Then the threaded rod 8 is rotated to drive the fixed plate 9 to descend to squeeze and fix the edge of the mold. After the mold is heated, it is difficult to remove the mold because the mold is completely in contact with the heating assembly. At this time, the electric telescopic rod 12 pushes up the support plate 5 to separate the mold from the heating assembly, making it easier to remove the mold, reducing the difficulty of removing the high-temperature mold and making the operation more convenient. When the mold is installed, the support column 6 is rotated to adjust the direction of the fixed plate 9 to prevent the fixed plate 9 from obstructing the placement of the mold.

[0024] like Figure 2 As shown, the heating component includes a heating chamber 2 opened in the box body 1, and a heating liquid is contained in the heating chamber 2. A heat conduction groove 3 is arranged on the inner wall at the top of the heating chamber 2. The heat conduction groove 3 is made of metal. A fixing groove 4 matched with the heat conduction groove 3 is arranged on the top of the box body 1, and the fixing groove 4 is located between the fixing components. An observation window 17 matched with the heating chamber 2 is arranged on the outer wall of the box body 1. Electric heating blocks 13 are arranged on the inner wall and the inner wall of the bottom of the heating chamber 2. A control panel 14 is installed on the outer wall of the box body 1, and the control panel 14 is connected to the electric heating block 13 through a wire. When the mold is heated, the electric heating block 13 heats the heating liquid. As the temperature of the heating liquid increases, the heat conduction groove 3 conducts the heat of the heating liquid to heat the metal mold placed in the heat conduction groove 3. Compared with the traditional heating device, various parts of the mold are heated at the same time, so that the mold is heated more evenly to prevent uneven heating from affecting the casting quality. The control panel 14 is convenient for controlling the temperature of the electric heating block 13.

[0025] like Figure 3 As shown, the top outer wall of the support plate 5 and the bottom outer wall of the fixed plate 9 are both provided with anti-skid pads 10, and the anti-skid pads 10 are respectively matched with the support plate 5 and the fixed plate 9. The thickness of the anti-skid pads 10 is less than that of the support plate 5 and the fixed plate 9. When the mold is fixed, the anti-skid pads 10 increase the friction between the support plate 5, the fixed plate 9 and the mold, and the mold is more stable and not easy to fall off.

[0026] like Figure 1 As shown, a temperature sensor 15 is installed on the inner wall of the bottom of the heating chamber 2, and a display 16 is installed on the outer wall of the box body 1. The temperature sensor 15 is connected to the PLC controller through a wire, and the PLC controller is connected to the display 16 through a wire. The temperature sensor 15 monitors the temperature of the heating liquid, and the display 16 displays the temperature monitored by the temperature sensor 15.

[0027] like Figure 1 As shown, a filling port is provided at the top outer wall of the box body 1, and a cover plate 18 is installed at the filling port. A discharge port is provided at the bottom of the outer wall of the box body 1, and a sealing plug 19 is provided at the discharge port. The filling port is convenient for adding heating liquid, and the discharge hole is convenient for discharging heating liquid.

[0028] How this utility works:

[0029] During operation, the mold to be heated is placed in the heating assembly inside the box 1, most of the mold enters the box 1, and the edge of the mold is placed on the support plate 5. Then the threaded rod 8 is rotated to drive the fixed plate 9 to descend to squeeze and fix the edge of the mold. After the mold is heated, since the mold is completely attached to the heating assembly, it is difficult to remove the mold. At this time, the electric telescopic rod 12 pushes up the support plate 5 to separate the mold from the heating assembly, making it easier to remove the mold, reducing the difficulty of removing the high-temperature mold and making the operation more convenient. When installing the mold, the support column 6 is rotated to adjust the direction of the fixed plate 9 to prevent the fixed plate 9 from obstructing the placement of the mold.

[0030] When the mold is heated, the electric heating block 13 heats the heating liquid. As the temperature of the heating liquid increases, the heat conducting groove 3 conducts the heat of the heating liquid to heat the metal mold placed inside the heat conducting groove 3. Compared with the traditional heating device, all parts of the mold are heated at the same time, so that the mold is heated more evenly, and the uneven heating is prevented from affecting the casting quality. The control panel 14 is convenient for controlling the temperature of the electric heating block 13;

[0031] When fixing the mold, the anti-skid pad 10 increases the friction between the support plate 5, the fixing plate 9 and the mold, making the mold more stable and less likely to fall off. The temperature sensor 15 monitors the temperature of the heating liquid, and the display 16 displays the temperature monitored by the temperature sensor 15.

[0032] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
