DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0026] Example: Reference Figure 1 and Figure 2 An aluminum casting blanking die shown in the figure includes a lower die base 1, a template 5 is fixed to the middle of the upper end surface of the lower die base 1, a discharge port 501 is arranged at the bottom of the template 5, and an upper die base 2 is arranged above the lower die base 1, a fixed base 6 is fixed to the middle of the lower end surface of the upper die base 2, a punch 8 is fixed to the middle of the lower end surface of the fixed base 6, the punch 8 is docked with the template 5, and a die handle 7 is arranged in the middle of the upper die base 2, and the die handle 7 is connected to the punch 8.

[0027] At the same time, vertical stripper plates 601 are elastically installed at both ends of the lower end surface of the fixed seat 6, and the stripper plates 601 vertically penetrate the edge of the punch 8. In specific implementation, the lower end surface of the fixed seat 6 is provided with a receiving hole for the stripper plates 601 to be completely placed therein, and a spring is installed in the receiving hole to elastically push the fixed seat 6 out, forming an elastic installation, so that when the fixed seat 6 and the punch 8 are lowered, the stripper plates 601 can abut against the upper surface of the template 5 and retract into the receiving hole, which will not affect the punching, and when the fixed seat 6 and the punch 8 are reset as the upper die seat 2 rises, the stripper plates 601 can automatically pop out of the lower surface of the punch 8 under the action of the spring to push away the aluminum casting waste that is stuck on the lower surface of the punch 8 after punching, so as to discharge the waste, which is convenient to use.

[0028] like Figure 2 As shown, vertical guide pillars 3 are fixed at the four corners of the upper end surface of the lower die base 1, and guide cylinders 4 are fixed at the four corners of the upper die base 2 corresponding to the positions of the guide pillars 3, and the guide pillars 3 are vertically inserted into the guide cylinders 4.

[0029] Among them, specific cooperation Figure 3 , Figure 4 and Figure 5As shown, a lubrication tube 301 is provided at the top of the guide column 3, and a stud 302 is fixed to the lower end of the guide column 3. The stud 302 is fixed to the top of the guide column 3 by vertical threaded insertion, and an opening connected to the inside of the lubrication tube 301 is opened at the lower end of the stud 302 to facilitate filling of lubricating oil into the lubrication tube 301.

[0030] An oil storage sponge 304 filled with lubricating oil is placed in the lubrication tube 301, a movable cavity 305 is provided in the oil storage sponge 304, an extrusion ball 306 is provided in the movable cavity 305, and an oil outlet hole 303 for oil to flow out is provided on the surface of the lubrication tube 301. Therefore, when the lubrication tube 301 moves up and down with the guide column 3, the extrusion ball 306 can squeeze the side wall of the oil storage sponge 304 under the action of inertia, so that the oil can overflow through the oil outlet hole 303 to form self-lubrication.

[0031] At the same time, the inner wall of the guide cylinder 4 is provided with a thread groove 401 for retaining oil, which is beneficial to improving the self-lubricating effect.

[0032] Working principle of the utility model: when the aluminum casting blanking die is used, the docking guide of the lower die seat 1 and the upper die seat 2 is smoothly plugged and matched with the guide column 3 and the guide cylinder 4, wherein the guide column 3 can move quickly in the guide cylinder 4 to form a guide. The lubricating tube 301 detachably mounted on the top of the guide column 3 can conveniently store lubricating oil, specifically through the oil storage sponge 304 to store lubricating oil, so that the guide column 3 can move up and down in the guide cylinder 4. During the guiding process, the squeezing ball 306 inside the oil storage sponge 304 can move up and down along the movable cavity 305 under the action of inertia, so that the squeezing ball 306 can squeeze the side wall of the oil storage sponge 304, so that the oil in the oil storage sponge 304 can overflow through the oil outlet hole 303 on the surface of the lubricating tube 301 and enter between the guide column 3 and the guide cylinder 4, so as to reduce the wear between the guide column 3 and the guide cylinder 4, achieve a self-lubricating effect, and help to ensure the blanking accuracy of the blanking die when it is used for aluminum castings for a long time.

[0033] At the same time, since the inner wall of the guide cylinder 4 is provided with a thread groove 401 , the lubricating oil flowing out of the lubricating pipe 301 can be further guided by the thread groove 401 so that the lubricating oil can evenly fill the entire inner wall surface of the guide cylinder 4 , thereby improving the lubrication effect.

[0034] In addition, after the device utilizes the upper die base 2 to dock with the lower die base 1, so that the punch 8 cooperates with the template 5 to punch out the aluminum casting to complete the punching operation, when the punch 8 is reset as the upper die base 2 rises, the unloading plate 601 loses the abutment with the upper surface of the template 5 and can pop out of the lower end surface of the punch 8 again, so that the elastically installed unloading plate 601 can be used to elastically push away the waste material that is tightly attached to the lower end surface of the punch 8 after punching, so as to avoid the waste material being stuck on the lower end surface of the punch 8 and affecting the subsequent punching. Therefore, the device is also convenient for discharging waste material and is easy to use.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to 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 utility model shall be included in the protection scope of the present utility model.
