Description

Technical Field

[0002] Aluminum is a lightweight, corrosion-resistant metal with good electrical and thermal conductivity. It is widely used in aerospace, automotive manufacturing, construction, packaging and other fields. Aluminum rod is a basic form of aluminum products and is made through a casting process. The casting process is to heat the aluminum raw material (such as aluminum ingot) to a molten state, and then inject it into a pre-prepared mold to cool and solidify into the desired shape. In this process, the design and quality of the casting mold are directly related to the dimensional accuracy, surface quality and production efficiency of the final product.

[0003] Chinese utility model patent CN221494131U provides an aluminum bar processing and casting mold, including a mold base, two fixed side plates are fixedly provided on the upper side of the mold base, the inner periphery of the fixed side plates is fixedly connected to the opening and closing hydraulic cylinder sleeve, and the inner peripheries of the hydraulic cylinder sleeve facing each other are slidably connected to the opening and closing hydraulic piston. Although the device is equipped with a circular cooling pipe and a coolant inlet and outlet, which can enable it to have a better cooling effect, it still has defects in actual processing and production. Specifically, during use, since the mold does not have a built-in heating system to preheat the mold itself, when high-temperature aluminum liquid is injected into the cold mold, it may cause a violent temperature difference reaction, which will not only affect the quality of the product (such as generating pores, cracks, etc.), but may also cause thermal stress damage to the mold. Therefore, it is necessary to improve the existing aluminum bar processing and casting mold and design a preheatable aluminum bar processing and casting mold. Utility Model Content

The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0021] Example: A casting die for processing aluminum bars, such as Figure 1-Figure 3 As shown, it includes a base plate 1, a sliding plate 2 and a mounting plate 21. The base plate 1 is the supporting carrier of the mold. The two sliding plates 2 are symmetrically arranged on the base plate 1, and the two mounting plates 21 are vertically fixed to the corresponding sliding plates 2 on the same side; it also includes: water outlet pipes 3, which are arranged in groups of two on the upper part of the mounting plate 21, and the water outlet pipes 3 all pass through the mounting plate 21; water inlet pipes 4, which are arranged in groups of two on the lower part of the mounting plate 21, and the water inlet pipes 4 also pass through the mounting plate 21; a front template 7, which is symmetrically arranged on the base plate 1, and the front template 7 is connected to the corresponding adjacent water outlet pipes 3 and water inlet pipes 4; a rear template 8, which is symmetrically arranged on the base plate 1, and the front template 7 is connected to the corresponding adjacent water outlet pipes 3 and The water inlet pipe 4 is connected, the rear template 8 and the front template 7 are completely consistent and symmetrically adapted on both sides, and the rear template 8 and the front template 7 can be sealed to form a complete set of casting molds. The front template 7 and the rear template 8 are provided with guide cavities that are connected to each other, and the guide cavities are respectively connected to the corresponding water outlet pipe 3 and water inlet pipe 4 on the same side; the metal plate 9 is symmetrically installed in the guide cavity inside the front template 7 and the rear template 8; the heating element is set on the bottom plate 1, and the heating element is used to heat the metal plate 9 so that the metal plate 9 heats the water injected into the front template 7 and the rear template 8, so that the mold composed of the front template 7 and the rear template 8 has both cooling and preheating functions, thereby improving the quality of the aluminum rod casting in the mold. The front template 7 and the rear template 8 are both replaceably installed between the water outlet pipe 3 and the water inlet pipe 4 on both sides, and the bottom plate 1 is supported at the bottom of the front template 7 and the rear template 8. The front template 7 and the rear template 8 can be replaced according to actual casting needs, thereby meeting the casting of aluminum rods of different sizes.

[0022] like Figure 3 As shown, the heating element is specifically a heating coil 14, which is installed on the base plate 1 through a mounting bracket. The heating coil 14 is sleeved on the outside of the front template 7 and the rear template 8. The heating coil 14 generates electromagnetic changes when energized, so that eddy currents are generated on the metal plate 9 and the metal plate 9 is heated by electromagnetic induction.

[0023] like Figure 1 As shown, a refrigerator 5 is symmetrically installed on the sliding plate 2. The refrigerator 5 is arranged at the water inlet of the water inlet pipe 4. The refrigerator 5 can cool the water injected into the water inlet pipe 4, so that the cooled water fills the guide cavity of the front template 7 and the rear template 8, thereby accelerating the cooling of the molten cast aluminum rod therein; a valve 6 is provided on the water outlet pipe 3, and the valve 6 is used to close or open the water outlet pipe 3, so that the guide cavity in the front template 7 and the rear template 8 can be efficiently filled with preheated water or replaced with cooling water.

[0024] like Figure 3 and Figure 4 As shown, it also includes a dual-axis motor 11, a fixed block 12 and a screw rod 13. The dual-axis motor 11 is installed on the bottom plate 1, and the screw rod 13 is symmetrically installed on the bidirectional output shaft of the dual-axis motor 11. The fixed block 12 is fixedly connected to the top surface of the sliding plate 2. The screw rods 13 at the two locations are respectively threadedly connected to the corresponding fixed blocks 12 on the same side. The dual-axis motor 11 rotates the screw rod 13 synchronously through the bidirectional output shaft, so that the screw rod 13 drives the fixed block 12 and the sliding plate 2 to move through the thread, so that the mounting plate 21 on the sliding plate 2 drives the corresponding front template 7 and rear template 8 on the same side to open and close through the water outlet pipe 3 and the water inlet pipe 4, thereby facilitating the demoulding and removal of the cooled aluminum rod.

[0025] When this mold is used to melt and cast aluminum rods, the user first installs the required front template 7 and rear template 8 symmetrically on the bottom plate 1, and maintains stability through the support on the bottom plate 1 to form a complete melting and casting mold. Before adding the high-temperature filtrate to the mold composed of the front template 7 and the rear template 8, first close the valve 6 on the outlet pipe 3, and fill the diversion chamber between the front template 7 and the rear template 8 with water through the water inlet pipe 4, and then start working after energizing the heating coil 14. The metal plate 9 located inside the front template 7 and the rear template 8 generates eddy currents and is heated by the principle of electromagnetic induction. The heated metal plate 9 then heats the water in the diversion chamber to ensure that when the molten aluminum liquid is injected into the mold, the mold itself is at an appropriate temperature, reducing the internal stress and defects caused by the temperature difference, thereby improving the quality of the final product. When the mold reaches the required preheating temperature, the molten aluminum liquid will be poured into the mold formed by the front mold The mold cavity is sealed by the plate 7 and the rear template 8, and the heating element continues to maintain the mold temperature until the aluminum liquid is completely filled and begins to solidify and form. After the aluminum rod is initially solidified, the valve 6 at the water outlet pipe 3 is opened and the refrigerant is started to supply cooling water to the water inlet pipe 4. The supplied cooling water continuously flows into the guide cavity in the front template 7 and the rear template 8, and gradually replaces the hot water used for heating before. At this time, the valve 6 on the water outlet pipe 3 can control the direction and speed of water flow to ensure that the entire mold is cooled evenly and quickly. After the cooling of the aluminum rod is completed, the dual-axis motor 11 is enabled, and the bidirectional output shaft on the dual-axis motor 11 drives the screw 13 to rotate, so that the sliding plate 2 fixed on the screw 13 moves in a direction away from each other, and the sliding plate 2 drives the mounting plate 21 thereon and the connected front template 7 and rear template 8 to be pulled outward, so that the operator can easily remove the formed and fully cooled aluminum rod finished product.

Any equivalent substitutions made within the principles of the present invention shall be included within the scope of protection of the present invention. Any matters not fully described in the present invention are prior art known to those skilled in the art.
