Description

[0002] In the production process of wheel hub die casting, the mold core slider assembly of the wheel hub die casting mold, as a core forming component, directly determines the dimensional accuracy and surface quality of the wheel hub product. Due to the high-temperature metal flow and release agent spraying processes involved in the die casting process, the surface of the mold core slider assembly and the joint gap are prone to residual metal debris, scale, oil stains, release agent residues and other impurities. If these impurities are not thoroughly cleaned in time, not only will it cause surface defects (such as pitting, scratches, shrinkage, etc.) in the subsequent die casting products, but also may cause the mold core slider assembly to jam, affecting the smoothness of the mold opening and closing action, and even shortening the service life of the mold. Currently, the cleaning of the mold core slider assembly mainly relies on manual labor. Since the mold core slider assembly is mostly an irregular curved surface structure, manual cleaning cannot reach the hidden parts such as the joint gap and grooves, which may result in incomplete cleaning. Therefore, the mold core slider assembly needs to be disassembled from the mold, and the mold core and the inner slider are cleaned one by one. This method not only is tedious and time-consuming, but also has low cleaning efficiency.

[0023] The technical solutions provided by the embodiments of the present application are described below in conjunction with the drawings.

[0024] Referring to Figures 1 to 8 The present application provides a wheel hub die casting mold linkage type cleaning device, comprising a bottom plate 1, a turnover mechanism 2 and a rotating disc linkage mechanism 3.

[0025] Among them, the middle part of the bottom plate 1 is provided with a positioning table 11, the positioning table 11 is used for carrying and positioning the die core slider assembly of the wheel hub die casting mold, the die core slider assembly includes a die core and a plurality of mold inner sliders 100, the plurality of mold inner sliders 100 are spliced into a complete ring, and the die core is located between the plurality of mold inner sliders 100.

[0026] The wheel hub die casting mold linkage type cleaning device aims to realize the synchronous opening of the plurality of mold inner sliders 100, to facilitate the cleaning of the plurality of mold inner sliders 100 and the die core, improve the cleaning efficiency and cleanliness, reduce the operation difficulty, and the reset is reliable, and the mold assembly precision is guaranteed.

[0027] Furthermore, the number of flipping mechanisms 2 is the same as the number of slides 100 in the mold, and they correspond one to one. The multiple flipping mechanisms 2 are distributed symmetrically around the center of the positioning platform 11. Each flipping mechanism 2 includes a base 21 slidably mounted on the base plate 1, a flap 22 rotatably mounted on the base 21, and a drive device mounted on the base 21 and connected to the flap 22. The flap 22 is used to fix the slide 100 in the mold, and the drive device is used to drive the flap 22 to perform a flipping action.

[0028] Furthermore, the turntable linkage mechanism 3 is arranged at the bottom of the base plate 1 and is simultaneously connected to multiple bases 21. When any base 21 slides on the base plate 1, it can drive the other bases 21 to slide synchronously through the turntable linkage mechanism 3 to simultaneously approach or move away from the positioning platform 11.

[0029] When working, Figure 7 As shown, the mold slider assembly is placed on the base plate 1 and supported and positioned by the positioning platform 11; then, one of the bases 21 is pushed to slide toward the center of the base plate 1 (or toward the mold slider assembly), and the base 21 drives the other bases 21 to slide synchronously toward the mold slider assembly through the turntable linkage mechanism 3 until each flap 22 abuts against the outer side of the corresponding mold inner slider 100, and then each flap 22 is fixed to the corresponding mold inner slider 100; then, one of the bases 21 is pulled to slide in the direction away from the mold slider assembly to return it to its initial position, and then the driving device drives the flap 22 to drive the mold inner slider 100 to perform a flipping action (as shown in FIG. Figure 8 As shown), multiple mold inner sliders 100 are opened synchronously, and multiple mold inner sliders 100 and mold core are cleaned with the help of tools such as air blowing nozzles; after cleaning, the driving device drives the flip plate 22 to drive the mold inner slider 100 to flip back and reset; one of the bases 21 is pushed toward the center of the bottom plate 1 again, and the base 21 drives the other bases 21 to slide synchronously toward the mold core slider assembly through the turntable linkage mechanism 3, so that the multiple mold inner sliders 100 are accurately reset to the initial annular splicing state, and finally the fixation between the flip plate 22 and the mold inner slider 100 is released to complete the cleaning operation.

[0030] It can be seen that the linkage type cleaning device for wheel hub die-casting mold realizes that when any one of the bases 21 slides, the other bases 21 are driven to move close to or away from the positioning table 11, so that the plurality of mold inner sliders 100 are simultaneously opened or closed, the mold inner slider 100 is fixed by the turning plate 22, the turning plate 22 is driven by the driving device to drive the mold inner slider 100 to turn, so that the cleaning operation is facilitated, the preparation before cleaning and the resetting process after cleaning are greatly simplified, the operation efficiency is improved, and the plurality of mold inner sliders 100 can be accurately reset to the initial annular splicing state after cleaning, the positioning error of manual assembly is avoided, and the mold closing precision is ensured.

[0031] Referring to Figure 1 The positioning table 11 in the embodiment includes a circular table located at the center of the bottom plate 1 and a plurality of support tables uniformly distributed around the circular table, and the mold cores and the plurality of mold inner sliders 100 are reliably supported and accurately positioned by cooperation of the circular table and the plurality of support tables.

[0032] Referring to Figure 2 The driving device includes a cylinder 23, two first supports 24 are fixed on the base 21, the cylinder 23 is pivotally connected between the two first supports 24 through a pin shaft, the output end of the cylinder 23 is inclined upward, and the output end of the cylinder 23 is rotationally connected to the top of the turning plate 22 through a joint bearing.

[0033] In the application, two second supports 25 and a limiting stop table 26 are also fixed on the base 21, the middle parts on both sides of the turning plate 22 are pivotally connected between the two second supports 25 through pin shafts, and the limiting stop table 26 is located on the side of the turning plate 22 away from the positioning table 11.

[0034] When the driving device drives the turning plate 22 to turn, the turning plate 22 can be switched between the initial state and the cleaning state.

[0035] The initial state is that the turning plate 22 is distributed in the vertical direction, and the side away from the positioning table 11 is stopped by the limiting stop table 26; the cleaning state is that the turning plate 22 is driven to rotate by the cylinder 23, specifically, the output end of the cylinder 23 is retracted and pulls the turning plate 22 to rotate, so that the upper end of the turning plate 22 is away from the positioning table 11 and the lower end is close to the positioning table 11, so as to reach the inclined or horizontal distribution state, and the inclined distribution state is preferred in the embodiment.

[0036] It can be understood that in the process of driving the turning plate 22 to rotate by the cylinder 23, the cylinder 23 itself will also rotate to a certain extent.

[0037] The turnover plate 22 of the turnover mechanism 2 in the application can be driven to turn through the air cylinder 23, so that the mold inner slide block 100 fixed on the turnover plate 22 is switched between the initial state and the cleaning state, the cavity surface, the splicing surface and the dead angle of the mold inner slide block 100 are fully exposed, the residual impurities are easily removed, and the cleaning is ensured to be more thorough.

[0038] Referring to Figure 3 and Figure 7 , the outer side surface of the mold inner slide block 100 is provided with a positioning groove 1001, and the positioning groove 1001 is provided with a threaded hole 1002. The side of the turnover plate 22 facing the mold inner slide block 100 is provided with a positioning boss 27 matched with the positioning groove 1001, and the turnover plate 22 is provided with a through hole penetrating the center of the positioning boss 27. When the base 21 is pushed to slide towards the mold core slide block assembly, the turnover plate 22 abuts against the corresponding mold inner slide block 100, the positioning boss 27 can just fall into the positioning groove 1001, and the turnover plate 22 and the mold inner slide block 100 are fixed by a screw penetrating the through hole of the positioning boss 27 and the threaded hole 1002. Through the technical means, the accurate positioning and stable connection of the turnover plate 22 and the mold inner slide block 100 can be realized, the relative displacement of the two during the cleaning process is prevented, the cleaning effect is affected, and the turnover plate 22 and the mold inner slide block 100 are convenient to disassemble and install.

[0039] Referring to Figure 2 and Figure 3 , the side of the turnover plate 22 facing the mold inner slide block 100 is provided with a plurality of air blowing holes 221, and each air blowing hole 221 is provided with a compressed air connector 222, so that compressed air is introduced during the cleaning process, the outer surface of the mold inner slide block 100 is assisted to be cleaned, the residual impurities on the outer surface are effectively removed, and the cleaning cleanliness is further improved.

[0040] Referring to Figures 1 to 3 , the bottom plate 1 is fixedly provided with a plurality of guide rails 28 distributed in a radial manner, each base 21 is slidably connected to a corresponding guide rail 28 through a sliding block 29, and the guide rail 28 is provided with a stroke limiting block 210 for limiting the sliding stroke of the base 21, so that the sliding block 29 is prevented from being pulled out of the guide rail 28.

[0041] Referring to Figures 4 to 6 , the rotary disc linkage mechanism 3 comprises a rotary disc 31 and a plurality of connecting rods 32. The rotary disc 31 is rotatably installed at the bottom of the bottom plate 1 and coaxial with the mold core slide block assembly carried on the positioning table 11. The outer circumferential surface of the rotary disc 31 is integrally provided with a plurality of connecting arms 311 distributed in a central symmetry manner, the number of the connecting arms 311 and the connecting rods 32 is the same as that of the turnover mechanism 2, and the two ends of each connecting rod 32 are rotatably connected to a corresponding connecting arm 311 and a corresponding base 21.

[0042] Specifically, as Figure 5As shown, the bottom of each base 21 is fixed with a vertical shaft, one end of the connecting rod 32 is rotatably connected to the vertical shaft through a joint bearing, and the other end of the connecting rod 32 is rotatably connected to the connecting arm 311 through another joint bearing. In this way, the turntable linkage mechanism 3 converts the sliding of a single base 21 into the synchronous sliding of all bases 21 through the cooperation of the turntable 31 and the connecting rod 32, which is a clever design, has high transmission efficiency, ensures the synchronization of the operation of multiple turnover mechanisms 2, reduces the operation steps, and improves the work efficiency.

[0043] Among them, the bottom plate 1 is provided with a clearance groove corresponding to the position of the vertical shaft, which provides a clearance space for the sliding of the base 21 driven vertical shaft.

[0044] Referring to Figure 5 and Figure 6 , the bottom of the bottom plate 1 is provided with a plurality of support columns 12, the support columns 12 are fixed with mounting seats 33, the turntable 31 is sleeved outside the mounting seat 33, and the bearing 34 is arranged between the two.

[0045] Among them, the top of the mounting seat 33 is provided with an annular boss 331, and the outer circumferential surface of the annular boss 331 is provided with an annular step 332, and the inner ring of the bearing 34 is tightly fitted on the annular boss 331 and carried on the annular step 332. The upper and lower sides of the turntable 31 are respectively fixed with an upper cover plate 35 and a lower seat ring 36, and the outer ring of the bearing 34 is between the upper cover plate 35 and the lower seat ring 36. The present application ensures the stable rotation of the turntable 31 through this structure design, reduces the frictional resistance in the rotation process, makes the rotation of the turntable 31 more flexible and smooth, and further improves the operation performance of the turntable linkage mechanism 3.

[0046] In addition, the turnover mechanism 2 also includes a handle 211 for handheld, the handle 211 is fixedly connected to the base 21, and the handle 211 can be held by the operator to facilitate pushing or pulling the base 21.

[0047] Of course, in some other embodiments of the present application, the sliding of the base 21 can also be in an automatic driving mode, for example, a power device such as a linear module, an electric cylinder or a pneumatic cylinder can be installed at the bottom of the bottom plate 1, which is drivingly connected to the base 21 for realizing automatic sliding of the base 21 without manual pushing.

[0048] In the embodiment, the number of mold inner sliding blocks 100 is three, and correspondingly, the number of turnover mechanisms 2 and connecting rods 32 is also three.

[0049] In summary, the linkage type cleaning device for wheel hub die-casting die connects the bases 21 of multiple turnover mechanisms 2 through the turntable linkage mechanism 3, realizes that when any base 21 slides, other bases 21 are driven to be synchronized to move close to or away from the positioning table 11, ensures that multiple die inner sliders 100 are synchronized to open or close, and through the turnover plate 22 to fix the die inner slider 100, the turnover plate 22 is driven by the driving device to drive the die inner slider 100 to make a turnover action, so as to facilitate the cleaning operation, without operating one by one, greatly simplifying the preparation before cleaning and the resetting process after cleaning, improving the operation efficiency, and being able to ensure that the multiple die inner sliders 100 can be accurately reset to the initial annular splicing state after cleaning, avoiding the positioning error of manual assembly, and ensuring the die closing precision.
