It solves the problem that when the pressing die is in use, the stamped oil seal is inside the stamping groove, requiring workers to remove it. Moreover, there are multiple oil seals that need to be removed, which reduces the efficiency of oil seal removal and also reduces the efficiency of the pressing die.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency pressing device for floating oil seals, comprising a support frame and a lower mold. A first hydraulic cylinder is fixedly installed at the upper end of the support frame. An upper mold is disposed inside the support frame and positioned above the lower mold. The output shaft of the first hydraulic cylinder is fixedly connected to the top of the upper mold through a side wall penetrating the support frame. Multiple stamping columns are fixedly installed at equal intervals at the bottom of the upper mold. The two ends of the lower mold are rotatably connected to the side walls of both ends of the support frame via rotating rods. Multiple forming cavities are evenly spaced inside the top surface of the lower mold, with the positions of the forming cavities corresponding to the stamping columns. A reciprocating motor is fixedly installed on the right side wall of the support frame, and the output shaft of the reciprocating motor is fixedly connected to a rotating rod at the right end of the lower mold through a side wall penetrating the support frame.

The output shaft of the second hydraulic cylinder is fixedly connected to the bottom of the support platform, and the support platform is located below the lower mold. The width of the support platform is greater than the width of the lower mold, thereby facilitating the limiting of the lower mold.

[0008] Preferably, a linear motor is fixedly installed on the right side wall inside the support frame, and the side wall of the upper mold does not contact the side wall of the linear motor. The linear motor is positioned between the upper mold and the lower mold. A moving plate is fixedly installed on the moving end of the linear motor. Multiple electric push rods are fixedly installed at equal intervals on the bottom surface of the moving plate. The position layout of the electric push rods corresponds to the position layout of the molding cavity. Multiple through holes are equally spaced inside the bottom surface of the lower mold. The through holes correspond to the interior of the molding cavity and are connected to the interior of the molding cavity. The position of the through holes corresponds to the output shaft position of the electric push rod that moves to the top of the lower mold, thereby facilitating the electric push rod to push the internal components.

[0009] Preferably, a support plate is fixedly installed on the front side wall of the support platform, and a push plate is slidably connected to the upper end of the support platform and disposed between the lower mold and the support plate. An electric telescopic rod is fixedly installed on the front side wall of the support plate, and the output shaft of the electric telescopic rod is fixedly connected to the side wall of the push plate through the inside of the side wall of the support plate, thereby facilitating the ejection of the component on the support platform.

[0010] Preferably, a guide plate is fixedly installed on the rear side wall of the support platform and is inclined to facilitate the discharge of the pushed-out parts.

[0011] Preferably, the diameter of the through hole is larger than the diameter of the electric push rod output shaft, thereby facilitating the entry of the electric push rod into the interior of the molding cavity.

[0012] This invention provides a high-efficiency compression molding device for floating oil seals. It has the following advantages:

[0013] 1. The high-efficiency molding device for floating oil seals, when using the high-efficiency molding device for floating oil seals, through the cooperation between the set reciprocating motor and the lower mold, can make the lower mold flip after the stamping work, so that the molded part in the molding cavity can fall out and be easily removed.

[0014] 2. The high-efficiency molding device for floating oil seals allows for the convenient ejection of components from the molding cavity by an electric push rod that enters the through hole. This prevents the molded components from getting stuck inside the molding cavity and thus being unable to be easily removed. Attached Figure Description

A first hydraulic cylinder 5 is fixedly installed on the upper end of the support frame 1. An upper mold 2 is arranged inside the support frame 1 and is positioned above the lower mold 3. The output shaft of the first hydraulic cylinder 5 is fixedly connected to the top of the upper mold 2 through a side wall penetrating the support frame 1. Multiple stamping columns 4 are fixedly installed at equal intervals on the bottom of the upper mold 2. The two ends of the lower mold 3 are rotatably connected to the two end side walls of the support frame 1 through rotating rods. Multiple forming cavities 6 are evenly arranged inside the top surface of the lower mold 3. The positions of the forming cavities 6 and the stamping columns 4 are... Correspondingly, a reciprocating motor 11 is fixedly installed on the right side wall of the support frame 1. The output shaft of the reciprocating motor 11 is fixedly connected to the rotating rod at the right end of the lower mold 3 through the inside of the support frame 1. When stamping the floating oil seal component, the component to be stamped is placed inside the forming cavity 6. Then, the first hydraulic cylinder 5 is opened, causing the upper mold 2 to drive the stamping column 4 to press down. Then, the resetting operation is performed. After the component is formed, the reciprocating motor 11 is opened, causing the lower mold 3 to flip over, which can easily drop the component in the forming cavity 6, making it easy to remove it and improving the efficiency of the device.

[0023] Example 2

[0024] To facilitate the support of the lower mold 3 and the collection of the molded parts, in this embodiment, as follows: Figure 1-4 As shown, a support platform 7 is slidably connected inside the support frame 1. A second hydraulic cylinder 10 is symmetrically fixed between the bottom of the support platform 7 and the bottom of the support frame 1. The output shaft of the second hydraulic cylinder 10 is fixedly connected to the bottom of the support platform 7. The support platform 7 is located below the lower mold 3, and its width is greater than the width of the lower mold 3. A support plate 8 is fixedly installed on the front side wall of the support platform 7, and a push plate 17 is slidably connected to the upper end of the support platform 7, positioned between the lower mold 3 and the support plate 8. An electric telescopic rod 9 is fixedly installed on the front side wall of the support plate 8. The output shaft of rod 9 is fixedly connected to the side wall of push plate 17 through the inside of the side wall of support plate 8. A guide plate 12 is fixedly installed on the rear side wall of support platform 7 and is set at an inclination. When the lower mold 3 is flipped, the second hydraulic cylinder 10 is used to move support platform 7 downward to facilitate the flipping of lower mold 3. Then, the falling parts can fall onto support platform 7. At the same time, the electric telescopic rod 9 is opened to push the push plate 17 to push the parts placed on support platform 7 and move them to the outside of the device through guide plate 12 for easy collection.

[0025] Example 3

[0026] To facilitate the ejection of the floating oil seal, in this embodiment, as follows: Figure 1-3As shown, a linear motor 14 is fixedly installed on the right side wall inside the support frame 1. The side wall of the upper mold 2 does not contact the side wall of the linear motor 14, and the linear motor 14 is positioned between the upper mold 2 and the lower mold 3. A moving plate 15 is fixedly installed on the moving end of the linear motor 14. Multiple electric push rods 16 are fixedly installed at equal intervals on the bottom surface of the moving plate 15. The position layout of the electric push rods 16 corresponds to the position layout of the molding cavity 6. Multiple through holes 13 are equally spaced inside the bottom surface of the lower mold 3. The through holes 13 are respectively connected to the molding cavity 6. The internal parts of the through holes 13 correspond to each other and are connected to the internal parts of the molding cavity 6. The position of the through hole 13 corresponds to the position of the output shaft of the electric push rod 16 that moves to the top of the lower mold 3. The diameter of the through hole 13 is larger than the diameter of the output shaft of the electric push rod 16. After the lower mold 3 is flipped, the linear motor 14 is turned on, so that the moving plate 15 moves to the top of the lower mold 3, so that the electric push rod 16 is fully opened and its output shaft enters the internal parts of the molding cavity 6 through the through hole 13, and pushes the parts in the molding cavity 6 downward.

[0027] It should be noted that in this embodiment, when using the high-efficiency compression molding device for floating oil seals, such as Figure 1-4 As shown, when stamping the floating oil seal components, the components to be stamped are placed inside the forming cavity 6. Then, the first hydraulic cylinder 5 is opened, causing the upper mold 2 to drive the stamping column 4 downward to press down. After the component is formed, when the lower mold 3 is flipped, the second hydraulic cylinder 10 is used to move the support platform 7 downward. The reciprocating motor 11 is turned on to flip the lower mold 3. After the lower mold 3 is flipped, the linear motor 14 is turned on, causing the moving plate 15 to move above the lower mold 3. The electric push rod 16 is fully opened, and its output shaft enters the forming cavity 6 through the through hole 13. The component in the forming cavity 6 is pushed downward, which can easily make the component in the forming cavity 6 fall down, making it easy to remove. This improves the efficiency of the device. Then, the fallen component falls onto the support platform 7. At the same time, the electric telescopic rod 9 is opened, causing the push plate 17 to push the component placed on the support platform 7 and move it to the outside of the device through the guide plate 12 for easy collection.
