A power mechanism Ⅰ that drives the screw rod Ⅰ14 to rotate is fixedly connected to the sliding bracket 13, and a power mechanism Ⅱ that drives the screw rod Ⅱ35 to rotate is fixedly connected to the lifting bracket 34;

[0040] The molding die II50 includes a plurality of sleeve-connected sliding dies II52, a plurality of telescopic mechanisms V51 are arranged on the moving seat 36, the telescopic ends of the plurality of telescopic mechanisms V51 are respectively fixedly connected to the plurality of sliding dies II52, the telescopic mechanisms V51 at the ends are fixedly connected to the moving seat 36, the plurality of telescopic mechanisms V51 are stacked in sequence, and one telescopic mechanism V51 is fixedly connected to the telescopic end of another telescopic mechanism V51;

[0042] The sliding mold II 52 is in a sleeve shape or a column shape, the innermost sliding mold II 52 is in a column shape, and the plurality of sliding molds II 52 sleeved on the outer side of the column-shaped sliding mold II 52 are in a sleeve shape;

[0044] When in use, the telescopic mechanism II 22 is started. The telescopic mechanism II 22 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II 22 drives the mold side plate 23 to move. Figure 1 As shown, the sides of the four mold side plates 23 are in contact with each other, and then the positions of the four mold side plates 23 are adjusted, the position of the molding mold I40 in the space enclosed by the four mold side plates 23 is adjusted, and the size of the shape enclosed by the four mold side plates 23 is adjusted. According to different usage requirements, the shape of the casting and the position of the groove, hole or stepped groove formed by the molding mold I40 are adjusted;

[0045] After the positions of the four mold side plates 23 are adjusted, the molten casting material is injected into the space enclosed by the four mold side plates 23, and the telescopic mechanism IV41 is started. The telescopic mechanism IV41 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism IV41 drives the sliding mold I42 to move, so that the sliding mold I42 is inserted into the space enclosed by the four mold side plates 23, and then the multiple sliding molds I42 push the molten casting material. The shapes of the positions where the multiple sliding molds I42 are inserted are grooves, holes or stepped grooves. Here, according to the needs, the shapes of the multiple sliding molds I42 extending into the space enclosed by the four mold side plates 23 are adjusted, that is, when the multiple sliding molds I42 extend into the same height, they are holes or grooves. The holes here are that the multiple sliding molds I42 extend out of the molten casting material, and the grooves are that the multiple sliding molds I42 do not extend out of the molten casting material. The stepped grooves are that the multiple sliding molds I42 are not at the same height to form stepped grooves;

[0046] Furthermore, the number of the inserted sliding molds Ⅰ42 can be adjusted according to the diameter of the groove or hole to be formed by the processing, and the inserted sliding mold Ⅰ42 located at the outermost sliding mold Ⅰ42 determines the diameter of the groove or hole to be formed by the processing;

[0047] Further, the power mechanism I is started, and the power mechanism I is preferably a servo motor. The output shaft of the power mechanism I starts to rotate, and the output shaft of the power mechanism I drives the screw rod I14 to rotate. When the screw rod I14 rotates, it drives the sliding seat 31 to move laterally through the thread, thereby adjusting the position of the molding die II50. The telescopic mechanism III32 is started. The telescopic mechanism III32 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism III32 drives the molding die II50 to move, thereby adjusting the height of the molding die II50. The power mechanism II is started, and the output shaft of the power mechanism II starts to rotate. The output shaft of the power mechanism II drives the screw rod II35 to rotate. When the screw rod II35 rotates, it drives the moving seat 36 to move through the thread, and the moving seat 36 drives the molding die II50 to move, thereby adjusting the position of the molding die II50.

[0048] Further, the telescopic mechanism V51 is started. The telescopic mechanism V51 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism V51 drives the corresponding sliding mold II52 to move, so that multiple sliding molds II52 are inserted into the molten casting material. The positions where the multiple sliding molds II52 are inserted are shaped into grooves, holes or stepped grooves. Here, according to the needs, the shapes of the multiple sliding molds II52 extending into the space enclosed by the four mold side plates 23 are adjusted, that is, when the multiple sliding molds II52 extend to the same height, they are holes or grooves. The holes here are that the multiple sliding molds II52 move to the bottom of the bottom mold 21, and the grooves are that the multiple sliding molds II52 do not move to the bottom of the bottom mold 21. The stepped grooves are that the multiple sliding molds II52 are not at the same height to form stepped grooves.

[0049] Furthermore, the number of the inserted sliding molds II52 can be adjusted according to the diameter of the groove or hole to be formed by the processing, and the inserted sliding mold II52 located at the outermost sliding mold II52 determines the diameter of the groove or hole to be formed by the processing;

[0050] Furthermore, the molding mold I40 and the molding mold II50 can cooperate with each other, that is, the shapes of the multiple sliding molds II52 and the multiple sliding molds I42 are the same and correspond one to one, so that the multiple sliding molds II52 and the multiple sliding molds I42 can be interlaced with each other, enriching the shape of the formed stepped holes to meet the use requirements according to the requirements;

[0051] Furthermore, the flip motor 33 may be started. The flip motor 33 is preferably a servo motor. The output shaft of the flip motor 33 drives the molding die II 50 to move, and adjusts the angle of the molding die II 50 to meet more molding requirements.
