Description

Technical Field

[0001] This utility model relates to the field of steering wheel foam mold technology, specifically a borderless foam steering wheel foam mold with a pressing mechanism. Background Technology

[0002] In the production process of edgeless foamed steering wheels, injection molds are key equipment for product molding. Their operational stability and surface cleanliness directly affect the molding quality of the steering wheel. Currently, there are many problems with steering wheel injection molds on the market that urgently need to be solved during use: On the one hand, after the mold is completed and demolded, some foaming material residue and impurities often adhere to the surface of the cavity. If these residues and impurities are not thoroughly cleaned, they can easily cause the mold to close loosely during the second injection molding, resulting in defects such as gaps and material shortages in the molded product. This seriously affects the structural strength and appearance quality of the steering wheel, increases the product defect rate, and brings additional rework costs and efficiency losses to the manufacturing enterprise. On the other hand, existing technologies for cleaning impurities on mold surfaces largely rely on manual operation. Operators must manually wipe or scrape the mold surface after each demolding, which is not only cumbersome and time-consuming, but also highly susceptible to human error, making it difficult to guarantee the thoroughness of impurity removal. Especially for complex areas such as mold edges and cavities, manual cleaning is more prone to omissions, further exacerbating quality risks associated with secondary injection molding. Utility Model Content

[0003] The purpose of this invention is to provide a foam mold for a borderless foamed steering wheel with a pressing mechanism, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a foam mold for a borderless foamed steering wheel with a pressing mechanism, comprising a base, a hydraulic device, and a support plate. The hydraulic device is fixed at the center of the top of the base, and the support plate is fixed at the top of the hydraulic device. Sleeves are fixed at the four corners of the top of the base, and push rods are inserted into the inside of the sleeves. The top of the push rods is connected to the bottom of the support plate. A mold is detachably mounted at the center of the top of the support plate. Grooves are symmetrically fixed on both sides of the top of the support plate. A sliding groove is formed inside the groove, and a slider is slidably connected inside the sliding groove. A groove block is fixed to the inner side of the slider. An auxiliary component is provided at the top of the slider. A fixing component is threaded to the side wall of the groove, and a cleaning component is provided at the top of the auxiliary component.

[0005] Preferably, the side wall of the slider has an insertion hole, and the fixing member extends through the slot plate into the interior of the slider to fix it.

[0006] Preferably, the inner side of the groove plate is provided with a strip groove, and the groove block is connected to the slider through the strip groove.

[0007] Preferably, the auxiliary component includes a support block, which is fixed to the top of the slider. A limiting tube is rotatably connected to the inner side of the support block. A limiting block is fixed to the top of the inner side of the limiting tube, and the other end of the limiting block is slidably connected to the inside of the support block. A plug rod is inserted into the inside of the limiting tube.

[0008] Preferably, the side wall of the support block is provided with an arc-shaped groove, and a limit block is slidably connected inside the arc-shaped groove.

[0009] Preferably, the cleaning component includes a horizontal plate, which is fixed to the inner side of the top end of the insertion rod, and a scraper is fixed to the bottom end of the horizontal plate, and the scraper is in an inclined state.

[0010] Preferably, a through hole is provided at the center of the slot block, and the through hole matches the insertion rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The strip groove on the inner side of the trough plate forms a sliding fit with the trough block, providing precise guidance for the movement of the slider and ensuring its straightness. Combined with the smooth sliding of the slider along the trough plate groove, the position adjustment of the auxiliary parts and cleaning parts is more accurate. The sleeve is vertically welded to the base and the top rod is firmly connected to the support plate. The overall structure is firmly welded. Combined with the clearance fit design between the various parts, the movement jamming phenomenon is reduced and the service life of the equipment is extended. The slider drives the support block, limit tube and other components to move. Combined with the sliding of the limit block in the arc groove of the support block, the rotation angle of the limit tube can be flexibly adjusted so that the cleaning parts (horizontal plate and scraper) at the top of the insertion rod are accurately positioned on the mold surface. The scraper is set at an angle and the bottom edge is rounded. It can not only efficiently remove the foaming material and impurities remaining on the mold surface, but also avoid scratching the mold, reduce the tediousness of manual cleaning and improve the preparation efficiency of the mold for reuse. The slider can slide freely along the groove plate and be quickly fixed by the fastener. The lifting and lowering of the insertion rod in the limiting tube and the rotation adjustment of the limiting tube allow the cleaning parts to adapt to the cleaning needs of different molds. The adjustment process is convenient and efficient. The sliding cooperation and snap-fit ​​limiting design between the components ensure the positional stability during the cleaning operation, further guaranteeing the cleaning effect and the safety of equipment operation.

[0015] Please see Figure 1-5 This utility model provides a technical solution for a foam mold for a borderless foamed steering wheel with a pressing mechanism: A foam mold for a borderless foamed steering wheel with a pressing mechanism includes a base 1, a hydraulic device 5, and a support plate 4. The support plate 4 has a mold mounting hole in its center, and a positioning pin and a set of fastening bolts are installed in the hole for fixing the mold 6. The hydraulic device 5 is fixed at the center of the top of the base 1. It consists of a hydraulic pump station, a double-acting hydraulic cylinder, an electromagnetic reversing valve, and a pressure sensor. The device is equipped with a pressure regulating device, which can set a suitable pressing force according to the mold specifications. During operation, the extension and retraction of the piston rod drives the support plate and the mold 6 to complete the lifting and lowering action. The support plate 4 is fixed at the top of the hydraulic device 5. Sleeves 2 are fixed at the four corners of the top of the base 1. The inner wall of the sleeves 2 is sprayed with a wear-resistant lubricating coating. The sleeves are vertically welded to the four corners of the top of the base 1. A push rod 3 is inserted inside the sleeve 2. When the hydraulic device 5 drives the support plate to rise and fall, the push rod can move synchronously with the support plate, working with the sleeve 2 to share the weight of the mold 6, improving the load-bearing stability of the support plate. The top of the push rod 3 is connected to the bottom of the support plate 4. The mold 6 is detachably installed at the center of the top of the support plate 4. Grooves 7 are symmetrically fixed on both sides of the top of the support plate 4. The strip-shaped grooves opened on the inner side of the grooves 7 form a sliding fit with the groove block 9, ensuring the straightness of the movement of the slider 8. The grooves are formed inside the grooves 7. Furthermore, a slider 8 is slidably connected inside the slid groove. The slider 8 can slide freely along the slid groove of the slid plate, thereby adjusting the position of the auxiliary component and the cleaning component. A groove block 9 is fixed inside the slider 8, and an auxiliary component is provided at the top of the slider 8. A fixing component 11 is threadedly connected to the side wall of the slid plate 7. A cleaning component is provided at the top of the auxiliary component. An insertion hole is opened on the side wall of the slider 8. The fixing component 11 extends through the slid plate 7 into the interior of the slider 8 to fix it. A strip-shaped slid groove is opened inside the slid plate 7, and the groove block 9 is connected to the slider 8 through the strip-shaped slid groove.

[0016] The auxiliary components include a support block 10, which is fixed to the top of the slider 8. The support block 10 has an L-shaped structure and is vertically welded to the top surface of the slider 8. A circular bearing seat is provided on the inner side for mounting the rotating shaft of the limiting tube 12. The limiting tube 12 is rotatably connected to the inner side of the support block 10. The inner diameter of the limiting tube 12 is clearance-fitted with the outer diameter of the insertion rod 14, allowing the insertion rod to move smoothly up and down inside the tube. A limiting block 13 is fixed to the top of the inner side of the limiting tube 12. One end of the limiting block 13 is fixedly connected to the limiting tube 12 by bolts, and the other end is embedded in the arc-shaped groove of the support block 10. The surface of the limiting block is covered with a polyoxymethylene wear-resistant sleeve, which can limit the rotation angle of the limiting tube 12 when sliding in the arc-shaped groove. The other end of the limiting block 13 is slidably connected to the inside of the support block 10. The insertion rod 14 is inserted into the inside of the limiting tube 12. An arc-shaped groove is opened on the side wall of the support block 10, and the limiting block 13 is slidably connected inside the arc-shaped groove.

[0017] The cleaning component includes a horizontal plate 15, which is fixed to the inner side of the top of the insert rod 14. A scraper 16 is fixed to the bottom of the horizontal plate 15. The bottom edge of the scraper 16 is rounded to ensure the cleaning effect without damaging the mold surface. It is used to clean the residual foaming material and impurities on the mold surface. The scraper 16 is inclined. A through hole is opened at the center of the groove block 9, and the through hole matches the insert rod 14.

[0018] Working Principle: When using a borderless foamed steering wheel mold with a pressing mechanism, the user places the metal support frame of the steering wheel into the mold 6, then snaps the upper mold shut. After snapping shut, the external control unit controls the hydraulic equipment 5 to press the mold 6 upward through the support plate 4. During the pressing process, the support plate 4 is limited by the cooperation of the sleeve 2 and the push rod 3. The mold 6 is pressed to perform the injection molding. After the injection molding is completed, the molded steering wheel is removed. Then, the user rotates the horizontal plate 15 upward. During the rotation, the limiting tube 12 rotates simultaneously and is limited by the movement of the limiting block 13 in the arc-shaped groove inside the support block 10. When the horizontal plate 15 rotates to the top of the mold 6, the user moves the horizontal plate 15 upward. Pushing downwards, the insert rod 14 moves downwards inside the limiting tube 12 and inserts into the groove block 9 for locking and limiting. At this time, the scraper 16 is attached to the surface of the mold 6. Then the user pushes the horizontal plate 15 forward. When pushing, the slider 8 slides inside the groove plate 7 through the support block 10. Then the scraper 16 cleans the impurities stuck to the surface of the mold 6. After cleaning, the user resets the horizontal plate 15. After resetting, the user pulls the horizontal plate 15 upwards and moves it upwards through the insert rod 14 to pull it out from inside the groove block 9. After pulling it out, the user rotates the horizontal plate 15 to reset it. After resetting, the horizontal plate 15 and the scraper 16 stay in front of the mold 6. Then the user inserts the fixing part 11 through the groove plate 7 into the inside of the slider 8 for fixing. After fixing, the secondary injection molding can be performed.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
