[0016] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] according to Figure 1 , Figure 2 , Figure 3 As shown, a die for processing aluminum castings includes: a lower die base 1, with multiple guide pillars 2 arranged longitudinally around the lower die base 1; a male die plate 3, which is spaced above the lower die base 1 by spacers, and a male die core 4 is provided at the center of the top of the male die plate 3; an upper die base 5, which is disposed above the male die plate 3 and cooperates with each of the guide pillars 2 through a first sliding sleeve, a female die plate 6 is fixedly disposed at the bottom of the upper die base 5, and a female die core 7 corresponding to the male die core 4 is provided at the center of the female die plate 6; and a stripping die plate 8, which is disposed between the lower die base 1 and the male die plate 3, and a plurality of ejector pins 9 penetrating the male die core 4 are provided at the top of the stripping die plate 8, and lifting rods 10 are arranged around the stripping die plate 8, which sequentially penetrate the male die plate 3 and the upper die base 5, and a lifting cap 11 that cooperates with the top of the upper die base 5 is provided at the top of the lifting rods 10.

[0018] With the above setup, the processing mold is installed on the stamping equipment. The lower mold base 1 is fixedly connected to the worktable, and the upper mold base 5 is connected to the slider of the stamping equipment. When the stamping equipment is started, the upper mold base 5 drives the female mold plate 6 to reciprocate longitudinally, thereby enabling the female mold core 7 and the male mold core 4 to cooperate in completing the stamping and cutting of the fed sheet metal. When the upper mold base 5 moves upward, the lifting rod 10 drives the ejector plate 8 to float upward, causing the ejector pins 9 to lift the workpiece from the male mold core 4 and complete the demolding action, thus solving the problem of aluminum parts sticking to the mold. In addition, since the demolding is automatic, the work efficiency is improved, and the multiple ejector pins 9 effectively avoid workpiece deformation and ensure production quality.

[0019] The top end of the lifting rod 10 is provided with a screw hole, the lifting cap 11 is engaged with the screw hole, and a buffer pad 12 is provided between the lifting cap 11 and the upper mold base 5.

[0020] With this setting, when the upper mold base 5 moves upward, the buffer pad 12 contacts the lifting cap 11, thereby reducing the impact force of the contact and preventing the ejector pin 9 from causing scratches to the workpiece, thus effectively protecting the tool.

[0021] The male template 3 is fitted around the guide post 2, and the pad is sleeved on the guide post 2; a mold opening spring 13 is provided between the upper mold base 5 and the male template 3. The male template 3 and the upper mold base 5 are respectively provided with a second sliding sleeve that cooperates with the lifting rod 10, and a return spring 14 is provided between the demolding template 8 and the male template 3.

[0022] The mold opening spring 13 facilitates the separation of the female mold plate 6 and the male mold plate 3 in a free state, thus enabling mold inspection. The return spring 14 effectively keeps the ejector plate 8 in contact with the lower mold base 1, preventing the ejector pin 9 from affecting the workpiece stamping process.

[0023] Each of the ejector pins 9 is a cylindrical structure, and its bottom end is threaded to engage with the ejector plate 8. The ejector pin 9 and the ejector plate 8 are fitted with a locking nut 15.

[0024] With this setting, workers can adjust the height of the ejector pin 9 using the locking nut 15, which avoids the ejector pin 9 being too high and leaving marks on the workpiece, and also avoids the problem of incomplete demolding caused by wear and tear of the ejector pin 9.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
