Description

Technical Field

[0001] This utility model relates to the field of oil seal molding devices, and in particular to a high-efficiency molding device for floating oil seals. Background Technology

[0002] Floating seals are a type of dynamic seal, offering good sealing performance in harsh working environments such as those with high levels of coal dust, silt, water, and gas. They are compact mechanical seals. A typical floating oil seal consists of a pair of wear-resistant metal rings (floating seal rings) and a pair of rubber rings, assembled within a dedicated sealing cavity (floating seal seat). When the two floating seal rings rotate relative to each other, their contacting end faces form a sealing surface perpendicular to the axis. The rubber rings, compressed within the sealing cavity formed with the floating seal seat, undergo elastic deformation. Under the elastic force of the rubber rings, a certain end-face pressure is generated on the sealing end faces. At this time, a very thin, essentially intact oil film forms and remains on the sealing end faces, placing the two sealing end faces in a boundary friction or semi-fluid friction condition. When the sealing end faces slide relative to each other with the relative rotation of the floating seal rings, the oil film provides a sealing effect.

[0003] A compression molding device is a combination of tools or equipment that uses pressure to press materials into desired shapes. It typically includes molds, presses, auxiliary equipment, etc., and through precise design and manufacturing, it can efficiently produce parts or products of various shapes.

[0004] In the production process of oil seals, a molding device is used. As a sealing element used for rotating shafts, the shape and dimensional accuracy of the oil seal have a crucial impact on its sealing performance. Application No. CN202121805615.3 discloses a high-efficiency molding device for floating oil seals, which can produce multiple floating oil seals at once, thereby improving production efficiency. However, during use, the molding block lacks protective measures during downward movement, potentially leading to workplace injuries. Furthermore, the finished product needs to be manually removed after molding, resulting in low efficiency and safety hazards.

[0005] Therefore, it is necessary to provide a high-efficiency molding device for floating oil seals to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a high-efficiency pressing device for floating oil seals, which solves the problem that some existing oil seal pressing devices lack protection during the downward movement of the pressing block and require manual material handling, resulting in significant safety hazards.

[0007] To solve the above technical problems, the present invention provides a high-efficiency molding device for floating oil seals, comprising: a frame, an inner side of the frame having a discharge assembly, and a protective assembly being provided on the top of the discharge assembly and located inside the frame;

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A schematic diagram of a preferred embodiment of the high-efficiency compression molding device for floating oil seals provided by this utility model; Figure 2 for Figure 1 A structural schematic diagram of the cross-sectional view of the protective cover shown; Figure 3 for Figure 1 The cross-sectional view of the template shown is a structural schematic diagram.

[0025] Figure 4 for Figure 1The structural schematic diagram of the rear view of the frame, the high-efficiency compression molding device for floating oil seal, includes: a frame 1, a discharge assembly 2 provided on the inner side of the frame 1, and a protective assembly 3 provided on the top of the discharge assembly 2 and located on the inner side of the frame 1.

[0026] The discharge assembly 2 includes a template 21 fixedly installed at the bottom of the inner side of the frame 1. A mold groove 22 is provided on the top of the template 21, and a push rod 23 is provided inside the mold groove 22 that can slide up and down.

[0027] like Figure 3 As shown, the top of the ejector rod 23 is located at the bottom of the mold groove 22. When the mold groove 22 is pressed, the bottom of the ejector rod 23 will be tightly attached to its interior, and the weight will be borne by the template 21, which will not cause damage to the electric telescopic rod 25.

[0028] The protective component 3 includes a protective cover 31 that can slide up and down and is located on the inside of the frame 1 and on the top of the template 21. The inner side of the protective cover 31 is slidably disposed on the lower pressure block 32. A set of hydraulic rods 33 is provided on the top of the lower pressure block 32. The top of the hydraulic rods 33 is fixed to the top of the inner wall of the frame 1. A pressure column for pressing the mold is provided at the bottom of the lower pressure block 32.

[0029] By using the protective cover 31 located outside the lower pressure block 32, since the bottom of the protective cover 31 is significantly lower than the bottom of the pressure column, when the bottom of the protective cover 31 abuts against the template 21, the bottom of the pressure column has not yet moved into the mold groove 22. Therefore, when the mold is working, if the worker's hand is in a dangerous position, the protective cover 31 will contact the arm in advance to remind the worker, thereby improving the protection effect.

[0030] The top left and right sides of the pressure block 32 are mirrored with connecting brackets 34. The inner sides of the two connecting brackets 34 are equipped with a set of sliding guide rods 35 that can slide up and down. The bottom ends of the two sets of sliding guide rods 35 are fixed to the top of the protective cover 31.

[0031] Each of the two connecting brackets 34 has a pressing spring 36 at its bottom and on the circumferential side of each of the two sets of sliding guide rods 35. The bottom ends of the two sets of pressing springs 36 are fixed to the top of the protective cover 31.

[0032] By setting the spring 36, when the hydraulic rod 33 drives the pressure column to the mold position, the lower pressure block 32 will move downward to the bottom inside the protective cover 31. At the same time, the spring 36 is compressed and deformed, so that the protective cover 31 is firmly upside down on the top of the template 21, preventing the arm from reaching in.

[0033] A sliding plate 24 is provided on the bottom inner side of the frame 1 and below the template 21, and can slide up and down. The bottom end of the top material rod 23 is fixedly connected to the top of the sliding plate 24. An electric telescopic rod 25 is provided on the bottom inner wall of the frame 1, and the telescopic end of the top of the electric telescopic rod 25 is fixedly connected to the bottom of the sliding plate 24.

[0034] After the output end of the electric telescopic rod 25 extends, it will drive the sliding plate 24 and the ejector rod 23 to rise, thereby ejecting the oil seal after molding out of the mold groove 22 to facilitate subsequent material removal.

[0035] The top of the template 21 is provided with a pusher plate 26 that can slide back and forth, and the inner side of the template 21 is provided with a rotating screw 27 that can rotate longitudinally. The bottom of the pusher plate 26 is threadedly connected to the circumferential side of the rotating screw 27.

[0036] When the pusher plate 26 stops, it is located in the gap between the pressure column and the protective cover 31, which will not affect the downward pressure of the protective cover 31. After the oil seal is pushed out, the pusher plate 26 is moved to the rear by rotating the screw 27, pushing the oil seal into the rear collection box 29 to complete the material removal, thus avoiding the problem of high safety hazards of manual material removal.

[0037] The rear end of the rotating screw 27 passes through the inner side of the template 21 and extends to its back side. The bottom of the template 21 is provided with a drive motor 28 for driving the rotating screw 27 to rotate. The output end of the drive motor 28 is connected to the rear end belt of the rotating screw 27. A collection box 29 is provided at the bottom of the back side of the frame 1.

[0038] The working principle of the high-efficiency compression molding device for floating oil seals provided by this utility model is as follows:

[0039] Step 1: Place the oil seal to be molded inside the mold groove 22 of the template 21. The extension of the output end of the hydraulic rod 33 drives the lower pressure block 32 to move downward. Under the action of the connecting frame 34 and the pressing spring 36, the protective cover 31 will move downward. Since the bottom of the protective cover 31 is significantly lower than the bottom of the pressure column, when the bottom of the protective cover 31 abuts against the template 21, the bottom of the pressure column has not yet moved into the mold groove 22. Therefore, when the mold is working, if the worker's hand is in a dangerous position, the protective cover 31 will contact the arm in advance to remind the worker, thereby improving the protection effect. When the protective cover 31 is pressed against the top of the template 21, the hydraulic rod 33 drives the lower pressure block 32 to continue to move downward, which causes the pressing spring 36 to deform and make the protective cover 31 firmly fasten above the template 21, preventing the arm from reaching in.

[0040] Step 2: After the molding is completed, the output end of the electric telescopic rod 25 extends to drive the sliding plate 24 and the ejector rod 23 to rise, thereby ejecting the molded oil seal out of the mold groove 22. Then, the drive motor 28 rotates to drive the rotating screw 27 to rotate, causing the pusher plate 26 to move backward and push the processed oil seal into the collection box 29, thus avoiding the safety hazards of manual material handling.

[0041] Compared with related technologies, the high-efficiency compression molding device for floating oil seals provided by this utility model has the following advantages:

[0042] Beneficial effects:

[0043] With the protective cover 31 being significantly lower than the pressure column at its bottom, when the bottom of the protective cover 31 abuts against the template 21, the bottom of the pressure column has not yet moved into the mold groove 22. Therefore, when the mold is working, if the worker's hand is in a dangerous position, the protective cover 31 will contact the arm in advance to remind the worker. Through the setting of the material discharge component 2, the safety hazards of manual material handling are avoided. The structure is simple and practical, and the safety of the device is effectively improved.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
