[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figure 1 and Figure 2This utility model provides an embodiment of a high-life automotive bearing seat mold steel casting and forging, comprising a base 1, a mold 5 fixedly connected to the top side of the base 1 by bolts or other fasteners, a base plate 7 slidably connected to the inner wall of the mold 5, a through hole on the bottom side of the mold 5, a cooling chamber inside the mold 5, water inlet pipes 4 fixedly connected to both sides of the mold 5, and water delivery pipes 3 fixedly connected to both sides of the top side of the base 1. The ends of the water delivery pipes 3 are externally connected to a cooling water circulation device, which includes a water tank, a water pump, and a delivery pipe. The cooling water circulation device delivers cooling water to the water delivery pipes 3, allowing the cooling water to flow into the cooling chamber through the water delivery pipes 3 and the water inlet pipes 4. This cooling chamber cools the internally stamped material. The degree of material cooling can be determined by installing a temperature sensor on the base 1 and detecting the material's temperature. Figure 1 , Figure 3 and Figure 4 A circular ring 18 is slidably connected inside the water supply pipe 3. One end of the circular ring 18 is inserted into the inside of the water inlet pipe 4. A slider 9 is fixedly connected to the top side of the circular ring 18. Both the front and rear sides of the slider 9 are connected to hoop rings 10 via torsion springs. A groove is opened on the outer wall of the water supply pipe 3, and the slider 9 is slidably connected inside the groove. A retaining plate 11 is fixedly connected to the middle end of the hoop ring 10. Both the front and rear sides of the outer wall of the water supply pipe 3 are provided with retaining slots, and the retaining plate 11 is engaged inside the retaining slots. A retaining rod 12 is fixedly connected to the bottom end of the front hoop ring 10, and a retaining groove is opened at the bottom end of the rear hoop ring 10, and the retaining rod 12 is engaged inside the retaining groove. By sliding the slider 9, the circular ring 18 is inserted into the water inlet pipe 4, thereby securing the water supply pipe 3 and the water inlet pipe 4. The gaps are sealed to prevent cooling water from flowing out. A sealing ring can be added between the water inlet pipe 4 and the water delivery pipe 4 to further improve the sealing effect. By rotating the hoop ring 10, the clamping plate 11 is engaged in the clamping groove, and the clamping rod 12 is engaged in the clamping groove, so that the hoop ring 10 is fixed in the water delivery pipe 3, thereby fixing the position of the slider 9, and thus fixing the position of the ring 18 to prevent it from falling off the water inlet pipe 4. A pressure device 6 is provided on the top side of the base 1. The pressure device 6 is a forging machine or other equipment that can provide stamping and other functions. Pressure is applied by the pressure device 6 to cause the steel material in the mold 5 to undergo plastic deformation in the cavity, gradually filling the cavity space and forming a prototype of the automobile bearing seat that is consistent with the shape of the cavity.
[0027] Reference Figure 1 and Figure 5A push rod 13 is slidably connected inside the base 1. A top rod 8 is fixedly connected to the top of the push rod 13. The top rod 8 passes through a through hole and abuts against the bottom side of the base plate 7. A round rod 16 is slidably connected to the front side inside the base 1. A rotating ring 17 is rotatably connected to the top of the round rod 16. A handle 2 is fixedly connected to the outer wall of the rotating ring 17. A strip groove is opened on the front side of the base 1. The handle 2 is slidably connected inside the strip groove. A positioning block 15 is fixedly connected to the bottom side inside the base 1. A limit groove is opened on the top side of the strip groove. The handle 2 is engaged inside the limit groove. A rotating plate 14 is rotatably connected to the bottom side inside the base 1. The bottom end of the push rod 13 abuts against the rear side of the rotating plate 14. The bottom end of the round rod 16 abuts against the rotating plate 14. The front side of plate 14 and the bottom side of the rear side of rotating plate 14 abut against the top side of positioning block 15. By using the grip rod 2 to push the round rod 16 downward, the round rod 16 pushes the front side of rotating plate 14 downward, thereby causing the rear side of rotating plate 14 to move upward. This causes the rear side of rotating plate 14 to push the push rod 13 to slide upward, causing the push rod 13 to push the top rod 8 upward, which in turn pushes the bottom plate 7 upward, thus pushing the stamped material out of the mold 5. This facilitates demolding by the workers. The round rod 16 is fixed by engaging the grip rod 2 into the limiting groove to prevent it from sliding downward. At the same time, the positioning block 15 restricts the rear side of rotating plate 14 to prevent it from being pushed by the push rod 13.
[0028] Working principle: First, the mold 5 is fixed to the base 1 with bolts and other fasteners, and the water inlet pipe 4 and the water outlet pipe 3 are connected together. Then, the slider 9 is slid to insert the ring 18 into the water inlet pipe 4, thereby sealing the gap between the water outlet pipe 3 and the water inlet pipe 4 and preventing the cooling water from flowing out of the gap. By rotating the clamping ring 10, the clamping plate 11 is engaged in the clamping groove, and the clamping rod 12 is engaged in the clamping groove, so that the clamping ring 10 is fixed in the water outlet pipe 3, thereby fixing the position of the slider 9, and thus fixing the position of the ring 18 to prevent it from detaching from the water inlet pipe 4. Then, the pressure device 6 is started to apply pressure, causing the steel material in the mold 5 to undergo plastic deformation in the cavity, gradually filling the cavity space and forming a prototype of the automobile bearing seat that conforms to the shape of the cavity. After the material is pressed and formed, the cooling is started. The water circulation equipment delivers cooling water to the water supply pipe 3 through the cooling water circulation device. The cooling water is then transported into the cooling chamber through the water supply pipe 3 and the water inlet pipe 4, thereby cooling the stamped material inside. After the material has cooled, the gripping rod 2 is first lifted upward to disengage it from the limiting groove. Then, the gripping rod 2 is rotated to rotate into the strip groove. The gripping rod 2 is then pushed downward, which pushes the round rod 16 downward, causing the round rod 16 to push the front side of the rotating plate 14 downward. This causes the rear side of the rotating plate 14 to move upward, which pushes the push rod 13 to slide upward. The push rod 13 then pushes the top rod 8 upward, which in turn pushes the bottom plate 7 upward, thus pushing the stamped material out of the mold 5, thereby completing the demolding process. Afterward, the above actions are repeated in reverse to reset the round rod 16 and other structures.
[0029] Finally, it should be noted that the above description 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 foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
