Its core function is to shape the ring-shaped blanks through processes such as pressure, temperature or cutting, so that its geometric dimensions, surface quality and mechanical properties are precisely matched to the design requirements of different industrial products.

[0003] The molds currently used in the outer ring processing field mainly rely on the extrusion action of the inner and outer molds to complete the shaping of ring parts. This processing mode requires the construction of a precise and complex mechanical structure for support, which inevitably leads to a highly complex overall mold structure. Also, the protrusions on the surface of the ring part after processing make it difficult to discharge the workpiece. Utility Model Content

[0004] The purpose of this utility model is to provide a mold for outer ring processing, which aims to solve the problem that in the prior art, the plastic forming of ring parts mainly relies on the extrusion action of the inner and outer molds. This processing mode requires the construction of a precise and complex mechanical structure for support, which inevitably leads to a highly complex overall mold structure. Also, the protrusions on the surface of the ring part after processing make it difficult to discharge the workpiece.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold for processing outer rings, comprising a lower mold plate and an upper mold plate. A central column is connected to the center of the upper surface of the lower mold plate. Two half-mold rings are connected to the upper surface of the lower mold plate via adjusting components. A rubber bladder is provided between the half-mold rings and the central column. A clamping ring is provided at the bottom of the rubber bladder, penetrating its bottom side and pressing against the upper surface of the lower mold plate. A water filling component is provided between the clamping ring and the lower mold plate. A guide component connected to the half-mold rings is provided on the surface of the lower mold plate. A clamping band is connected to the bottom side of the upper mold plate.

[0006] As a preferred embodiment of the mold for processing an outer ring according to this utility model, the adjusting component includes a vertical block, a lead screw, a handwheel, and a docking seat. The vertical block is connected to the side surface of the lower template, and a lead screw threadedly threaded through the interior of the vertical block is connected to it. The end of the lead screw is connected to the handwheel, and the other end of the lead screw is rotatably sleeved with a docking seat connected to the half mold ring.

[0007] As a preferred embodiment of the mold for processing an outer ring according to this utility model, the two half-rings are merged to form a complete ring, and the outer surface of the half-ring is an inclined surface, and the inner wall of the clamping ring is adapted to the outer wall of the ring formed by the merging of the two half-rings.

[0008] As a preferred mold for processing an outer ring according to this utility model, the clamping ring presses the rubber bladder against the surface of the lower template to form a sealed cavity.

[0009] As a preferred embodiment of the mold for outer ring processing according to this utility model, the water filling component includes a first water inlet groove, a second water inlet groove, and a connecting pipe fitting. The first water inlet groove is opened on the side surface of the lower template, and the surface of the clamping ring is provided with a second water inlet groove. A connecting pipe fitting connects the first water inlet groove and the second water inlet groove.

[0010] As a preferred embodiment of the mold for outer ring processing according to this utility model, the first water inlet groove and the second water inlet groove are connected by a connecting pipe fitting.

[0011] As a preferred embodiment of the mold for processing an outer ring according to this utility model, the guiding component includes a guide groove and a guide block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model fills the rubber bladder with water through the first water inlet groove, the connecting pipe fitting and the second water inlet groove. After the rubber bladder expands with water, it squeezes the annular blank to fit against the inner wall of the half mold ring to achieve shaping. During this process, the expansion force from the rubber bladder on the half mold ring can be borne by the setting of the clamping clamp, thereby ensuring the stability of the annular blank processing.

[0014] After the molding process is completed, the water inside the rubber bladder is discharged through the second water inlet, the connecting pipe and the first water inlet. When the handwheel drives the screw to rotate inside the block, it drives the half-mold ring to move axially through the docking seat. This allows the two half-mold rings to move away from each other, which facilitates the discharge of the molded ring part. Attached Figure Description

[0023] 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.

[0024] Please see Figures 1-6 The present invention provides the following technical solution: a mold for processing an outer ring, comprising a lower mold plate 1 and an upper mold plate 2. A central column 3 is connected to the center of the upper surface of the lower mold plate 1. Two half-mold rings 5 ​​are connected to the upper surface of the lower mold plate 1 respectively through an adjusting component 4. A rubber bladder 6 is provided between the half-mold rings 5 ​​and the central column 3. A clamping ring 7 is provided at the bottom of the rubber bladder 6, penetrating its bottom side and pressing against the upper surface of the lower mold plate 1. A water filling component 8 is provided between the clamping ring 7 and the lower mold plate 1. A guide component 9 connected to the half-mold rings 5 ​​is provided on the surface of the lower mold plate 1. A clamping band 10 is connected to the bottom side of the upper mold plate 2.

[0025] Preferably, the adjusting component 4 includes a block 401, a lead screw 402, a handwheel 403, and a docking seat 404. The block 401 is connected to the side surface of the lower template 1. The lead screw 402, which is threadedly connected to the block 401, passes through the interior of the block 401. The handwheel 403 is connected to the end of the lead screw 402. The other end of the lead screw 402 is rotatably sleeved with the docking seat 404, which is connected to the half mold ring 5.

[0026] In practical use, when the lead screw 402 rotates inside the vertical block 401, it can move axially through the threaded connection. When the lead screw 402 moves axially, it can drive the half mold ring 5 to move axially through the mating seat 404, thus realizing the position adjustment of the half mold ring 5.

[0027] Preferably, the two half-molding rings 5 ​​are merged to form a complete ring, and the outer surface of the half-molding ring 5 is a bevel, and the inner wall of the clamping ring 7 is adapted to the outer wall of the ring formed by the merging of the two half-molding rings 5.

[0028] In practical use, when the mold is closed, the clamping ring 7 presses against the surfaces of the two half-mold rings 5, thereby withstanding the outward extrusion force when the half-mold rings 5 ​​are subjected to internal extrusion, thus ensuring the stability of the outer ring processing.

[0029] Preferably, the clamping ring 7 presses the rubber bladder 6 against the surface of the lower template 1 to form a sealed cavity.

[0030] In practical use, when the rubber bladder 6 is continuously filled with water, it can increase the internal pressure, causing the rubber bladder 6 to expand, thus enabling the processing of the ring-shaped blank.

[0031] Preferably, the water filling component 8 includes a first water inlet 801, a second water inlet 802, and a connecting pipe 803. The first water inlet 801 is opened on the side surface of the lower template 1, and the second water inlet 802 is opened on the surface of the clamping ring 7. The connecting pipe 803 connects the first water inlet 801 and the second water inlet 802.

[0032] Preferably, the first water inlet tank 801 and the second water inlet tank 802 are connected by a connecting pipe fitting 803.

[0033] In practical use, water can enter the interior of the rubber bladder 6 through the first water inlet 801, the connecting pipe 803 and the second water inlet 802, thereby enabling the rubber bladder 6 to be filled with water.

[0034] Preferably, the guide component 9 includes a guide groove 901 and a guide block 902. The guide groove 901 is formed on the surface of the lower template 1, and the bottom side of the half-mold ring 5 is connected to a guide block 902 that is adapted to the size of the guide groove 901.

[0035] In practical use, when the half-mold ring 5 is subjected to a force, it can drive the guide block 902 to slide inside the guide groove 901. This can limit the movement of the half-mold ring 5, thereby ensuring the stability of the movement of the half-mold ring 5.

[0036] Working principle: When using this mold, the annular blank is first inserted into the annular gap formed by the rubber bladder 6 and the two half-mold rings 5. Then, the upper mold plate 2 drives the clamping band 10 to move towards the lower mold plate 1 to close the mold. Then, water is filled into the rubber bladder 6 through the first water inlet 801, the connecting pipe 803 and the second water inlet 802. After the rubber bladder 6 is filled with water and expands, it can squeeze the annular blank. When the annular blank is squeezed, it can fit against the inner wall of the half-mold ring 5 and achieve shaping. During this process, the clamping band 10 can withstand the expansion force from the rubber bladder 6 on the half-mold ring 5.

[0037] After the molding is completed, the upper template 2 drives the clamp 10 to move upward. Then, the water inside the rubber bladder 6 is discharged through the second water inlet 802, the connecting pipe 803 and the first water inlet 801. After the water is discharged, the rubber bladder 6 returns to its original shape. Then, the handwheel 403 is turned. When the handwheel 403 drives the screw 402 to rotate inside the block 401, it can move axially. When the screw 402 moves axially, it can drive the half mold ring 5 to move axially through the docking seat 404. This allows the two half mold rings 5 ​​to move away from each other. Finally, the molded ring part can be taken out.

[0038] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
