[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0027] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0028] Embodiments of this application provide a casting mold, such as Figures 1 to 3 As shown, the casting mold includes a first mold body 100, a second mold body 200, and a first heater 110.
[0029] like Figure 1 and Figure 2 As shown, a first heating channel is provided in the wall of the first mold 100. Exemplarily, the first heating channel can be arranged along a straight line, but in other embodiments, the first heating channel can also be arranged along a curve.
[0030] A first cavity is formed on the end face of the first mold 100. A second cavity is formed on the end face of the second mold 200 near the first cavity. The first mold 100 is mounted on the second mold 200, so that the first cavity and the second cavity are connected and form an injection chamber. The injection chamber is used to inject melt, and the melt solidifies in the injection chamber to form the desired product.
[0031] A first heater 110 is disposed within a first heating channel to heat a first mold 100. The first heater 110 generates heat and transfers the heat to the mold wall of the first mold 100, and then to the melt in the injection chamber. While the first heater 110 is heating the first mold 100, the first mold 100 can also transfer heat to the second mold 200.
[0032] For example, the melt injected into the injection chamber needs to be heated before it can solidify.
[0033] This application includes a first heater 110, which heats the melt in the injection chamber to solidify it. By placing the first heater 110 inside the first mold body 100 and allowing it to heat along the first heating channel within the mold body wall, heat can be directly transferred to the mold body wall and the melt in the injection chamber. Compared to traditional oven heating, this internal heating method significantly improves heating efficiency and shortens the heating cycle. This is because heat does not need to be gradually conducted to the interior through the outer wall of the mold shell, but is directly heated inside the mold, reducing heat transfer resistance and time, improving production efficiency, and saving energy.
[0034] For example, the first heater 110 includes, but is not limited to, a resistance heater, an electromagnetic heater, an infrared heater, a gas heater, etc.
[0035] like Figure 1 and Figure 2 As shown, in one embodiment, there are at least two first heating channels, which are sequentially distributed along the direction of gravity. During the casting process, the vent and melt inlet are sequentially distributed along the direction of gravity. Therefore, the melt gradually fills the casting channels from bottom to top along the direction of gravity. The sequential distribution of the first heating channels along the direction of gravity ensures uniform heating of the melt and allows for precise control of temperature and heating time. By precisely controlling the heater temperature and heating time, the solidification process of the melt can be more accurately controlled. This contributes to achieving high-quality product production and stable production cycles.
[0036] For example, two first heating channels are provided. In another embodiment, four first heating channels are provided. In another embodiment, five first heating channels are provided. In yet another embodiment, six first heating channels are provided. Figure 1 and Figure 2 As shown, in another embodiment, seven first heating channels are provided. The seven first heating channels can be arranged in pairs, and the remaining first heating channel is located at the top position in the direction of gravity.
[0037] For example, different first heaters 110 can be set to the same heating temperature or different heating temperatures. Different heating channels can be set to different heating temperatures, or the temperature of different heaters within the same channel can be adjusted as needed. This layered heating method can better adapt to the different temperature requirements of the melt in the injection chamber, improving the accuracy and uniformity of heating.
[0038] The number of first heaters 110 is at least two, and at least one first heater 110 is provided in each first heating channel.
[0039] For example, the number of first heaters 110 matches the number of first heating channels. In another embodiment, two first heaters 110 are provided in each first heating channel. In yet another embodiment, three first heaters 110 are provided in each first heating channel.
[0040] In one embodiment, the casting mold further includes a first controller, which is electrically connected to the first heater 110 and controls the temperature of the first heater 110.
[0041] For example, the first controller is, for instance, a central processing unit (CPU), a programmable logic controller (PLC), or an electronic device with logic control functions.
[0042] The first controller can monitor and adjust the temperature of the first heater 110 in real time, ensuring that the heater operates according to the preset temperature curve. This precise temperature control helps reduce temperature fluctuations and improves the stability and consistency of the heating process. By precisely controlling the temperature, the heating and solidification process of the melt can be optimized, reducing product defects such as shrinkage cavities and cracks caused by improper temperature.
[0043] The introduction of the first controller enables automated control of the heating process, reducing the need for manual intervention. This helps improve production efficiency, reduce labor intensity, and minimize errors caused by human factors.
[0044] In one embodiment, the first controller controls different first heaters 110 to heat to different temperatures, wherein, along the direction of gravity, the temperature of the first heater 110 located above is greater than the temperature of the first heater 110 located below.
[0045] like Figure 1 and Figure 2 As shown, exemplarily, four sets of first heating channels are provided. For ease of description, the four sets of first heating channels are named sequentially from bottom to top along the direction of gravity as the first heating group, the second heating group, the third heating group, and the fourth heating group. Each group includes at least one first heating channel, and each first heating channel is provided with at least one first heater 110. During use, the first controller controls the heating temperature of the first heater 110 in the first heating group to be 100°C to 120°C, the first controller controls the heating temperature of the first heater 110 in the second heating group to be 130°C to 140°C, the first controller controls the heating temperature of the first heater 110 in the third heating group to be 160°C to 170°C, and the first controller controls the heating temperature of the first heater 110 in the fourth heating group to be 190°C to 210°C. The first controller controls the first heater 110 to heat the first mold body 100 in segments, so that the melt gradually solidifies from top to bottom along the direction of gravity in the injection chamber.
[0046] By gradually increasing the heating temperature along the direction of gravity, the melt can be gradually solidified from top to bottom in the injection chamber. This temperature gradient ensures that the melt solidifies uniformly and orderly during the solidification process, reducing internal stress or defects caused by uneven temperature and improving the quality of the final product. Segmented heating allows different areas of the melt to reach their solidification conditions at different times, thus achieving a more efficient heating and solidification process. Compared to conventional external heating, this method achieves the desired solidification effect faster, shortening the production cycle. Because the heating temperature is controlled in segments, the thermal stress effect of high temperatures on the equipment materials can be reduced, thereby reducing the wear rate of the first mold 100 and the second mold 200 and extending the service life of the equipment.
[0047] In one embodiment, the casting mold further includes a frame and a telescopic component.
[0048] The frame is fixedly installed on the ground or other fixed platform. For example, the frame is fixedly installed on the ground or other fixed platform by means of welding, bolting or snap-fitting.
[0049] The first mold 100 is fixedly mounted on the frame. Exemplarily, the first mold 100 is fixedly mounted on the frame by means of welding, bolting, or snap-fitting.
[0050] The telescopic component is telescopic and is mounted on the frame. The second mold body 200 is mounted on the telescopic component. The telescopic component telescopic and moves the second mold body 200 toward the first mold body 100 so that the second mold body 200 is mounted on the first mold body 100, thereby merging the first cavity and the second cavity to form an injection chamber.
[0051] For example, telescopic components include, but are not limited to: hydraulic telescopic rods, pneumatic telescopic rods, electric actuators, threaded screw mechanisms, etc.
[0052] Compared to existing molds, which require manual installation and disassembly of the second mold 200 for each product manufactured, and repeated heating of the first mold 100 and the second mold 200 in an oven, taking at least twelve hours to produce one product, the present application utilizes a telescopic component to improve the efficiency of loading and unloading the second mold 200. Manual installation and removal of the second mold 200 from the first mold 100 are eliminated, taking only a few minutes. Furthermore, the first heater 110 further reduces heating time by several hours compared to oven heating, thus shortening the overall heating time of the casting mold. Therefore, the casting mold of this application significantly improves production efficiency.
[0053] like Figure 1As shown, in one embodiment, the casting mold further includes a flange 300 disposed on the inner wall of the first cavity. The flange 300 can partially fill the space of the injection chamber to control the filling shape of the melt in the injection chamber, thereby obtaining the desired product. In the prior art, the flange 300 is placed in an oven for heating along with the mold. The heat from the oven enters the mold from the outside in to heat the flange 300, resulting in low heating efficiency and poor heating effect. However, in the present application, the flange 300 is equipped with a first heater 110, so the first mold 100 and the second mold 200 do not need to be placed in the oven. The flange 300 can be detached and placed in the oven for heating. Furthermore, multiple flanges 300 can be heated sequentially in the oven. That is, multiple flanges 300 with different molds can be placed in the oven for heating in the same batch, heating multiple flanges 300 at once, which improves the heating efficiency of the flange 300. The flange 300 is placed directly in the oven for heating without the obstruction of the mold, which improves the heating effect of the flange 300. Therefore, the casting mold provided in the embodiment of the present application improves the baking heating efficiency and heating effect of the flange 300, greatly shortens the product production cycle, and improves production efficiency.
[0054] like Figure 3 and Figure 4 As shown, in one embodiment, a second heating channel is provided in the wall of the second mold 200; exemplaryly, the second heating channel can be arranged along a straight line, but in other embodiments, the second heating channel can also be arranged along a curve.
[0055] The casting mold also includes a second heater 210, which is disposed in a second heating channel to heat the second mold body 200.
[0056] For example, the second heater 210 includes, but is not limited to, a resistance heater, an electromagnetic heater, an infrared heater, a gas heater, etc.
[0057] The first heater 110 and the second heater 210 are respectively provided on the first mold body 100 and the second mold body 200, which can ensure that the melt in the injection chamber can be heated evenly during the pouring process. This uniform heating helps the melt flow and solidify evenly in the chamber, reduces internal stress or defects caused by uneven temperature, and improves the quality and consistency of the product.
[0058] like Figure 3 and Figure 4 As shown, in one embodiment, the number of second heating channels is at least two, and the at least two second heating channels are distributed sequentially along the direction of gravity;
[0059] For example, two second heating channels are provided. In another embodiment, four second heating channels are provided. In another embodiment, five second heating channels are provided. In yet another embodiment, six second heating channels are provided. Figure 3 and Figure 4 As shown, in another embodiment, seven second heating channels are provided. Among the seven first heating channels, they can be grouped in pairs, and the remaining second heating channel is located at the top position in the direction of gravity.
[0060] The number of second heaters 210 is at least two, and at least one second heater 210 is provided in each second heating channel.
[0061] For example, the number of second heaters 210 matches the number of second heating channels. In another embodiment, two second heaters 210 are provided in each second heating channel. In yet another embodiment, three second heaters 210 are provided in each second heating channel.
[0062] In one embodiment, the casting mold further includes a second controller, which is electrically connected to the second heater 210 and can control the temperature of the second heater 210.
[0063] For example, the second controller may be a central processing unit (CPU), a programmable logic controller (PLC), or an electronic device with logic control functions.
[0064] For example, the first controller and the second controller are configured separately. In another embodiment, the first controller and the second controller are integrated into one unit.
[0065] The second controller can monitor and adjust the temperature of the second heater 210 in real time, ensuring that the heater operates according to the preset temperature curve. This precise temperature control helps reduce temperature fluctuations and improves the stability and consistency of the heating process. By precisely controlling the temperature, the heating and solidification process of the melt can be optimized, reducing product defects such as shrinkage cavities and cracks caused by improper temperature.
[0066] The introduction of a second controller enables automated control of the heating process, reducing the need for manual intervention. This helps improve production efficiency, reduce labor intensity, and minimize errors caused by human factors.
[0067] The combined use of the first and second controllers ensures that the first heater 110 and the second heater 210 symmetrically heat the melt in the injection chamber. This symmetrical heating helps reduce product defects caused by uneven temperature and improves the overall quality of the product.
[0068] In one embodiment, the second controller controls different second heaters 210 to heat to different temperatures, wherein, along the direction of gravity, the temperature of the upper second heater 210 is greater than the temperature of the lower second heater 210.
[0069] like Figure 3 and Figure 4 As shown, exemplarily, four sets of second heating channels are provided. For ease of description, the four sets of second heating channels are named sequentially from bottom to top along the direction of gravity: first heating group, second heating group, third heating group, and fourth heating group. Each group includes at least one second heating channel, and each second heating channel is provided with at least one second heater 210. During use, the second controller controls the heating temperature of the second heater 210 in the second heating group to be 100°C to 120°C, the second controller controls the heating temperature of the second heater 210 in the second heating group to be 130°C to 140°C, the second controller controls the heating temperature of the second heater 210 in the third heating group to be 160°C to 170°C, and the second controller controls the heating temperature of the second heater 210 in the fourth heating group to be 190°C to 210°C. The second controller controls the second heater 210 to heat the second mold 200 in segments, so that the melt gradually solidifies from top to bottom along the direction of gravity in the injection chamber.
[0070] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0071] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
