[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figure 1-Figure 8 As shown, in the prior art, it is difficult to grind multiple surfaces at different angles, and multiple repeated clamping operations are required, which reduces the processing efficiency; and the problem that the connected synchronous step-by-step fine grinding and polishing processing cannot be achieved can be solved by the following solution: In this embodiment, a mold surface treatment device based on surface treatment includes a base 1, a T-shaped plate 11 is installed on the top of the base 1 through a fixed column, a rotating motor 13 is installed on the bottom of the T-shaped plate 11 through an electric cylinder slide module 12, and three groups of electric cylinder slide modules 12 and rotating motors 13 are provided and arranged at the bottom of each end of the T-shaped plate 11, and the output shaft of the rotating motor 13 is installed with a processing block 14 through a fixture; The processing block 14 is specifically a coarse grinding block, a fine grinding block and a polishing block, which are driven to rotate by the corresponding rotating motor 13, and the molds are contacted with the processing blocks one by one, so as to achieve step-by-step coarse grinding, fine grinding and polishing processing on the mold surface, thereby achieving high-quality processing of the mold surface; The mold needs to be polished after the following operations. First, check whether the mold surface is rusty, welded, scratched, cracked, or crushed. Second, remove the easily corroded accessories such as the guide plate, guide sleeve, dust cover, and nameplate on the mold, and protect the accessories that cannot be removed. Subsequently, calcium carbonate is evenly applied on the electroplating surface of the mold using a brush, and then the naturally air-dried calcium carbonate is wiped with a rag, rinsed with a cleaning solution and air-dried. After that, the mold is stripped with hydrochloric acid and pure water, and cleaned after stripping to prevent residual stripping liquid from corroding the mold surface. Finally, step-by-step grinding is performed, and repair and polishing are performed before subsequent electroplating.

[0020] A cross plate 15 is rotatably mounted on the fixed column, and multiple sets of universal adjustment components 2 are arranged at each end of the cross plate 15, so that the number of universal adjustment components 2 is greater than the number of processing blocks 14, so that when the mold is processed step by step, the mold before and after the processing is replaced synchronously, and combined with the rotation of the cross plate 15 on the fixed column, continuous step-by-step processing is realized, and the mold processing efficiency is further improved. An external motor is installed on the base 1, and an adapted gear set is installed on the output shaft of the external motor and the cross plate 15 to drive the cross plate 15 to intermittently rotate 90 degrees; The mold whose surface is to be polished is grabbed by the loading robot arm and placed on one of the placement platforms 23. The clamping and positioning assembly 3 fixes the mold, and the positioned and clamped mold is rotated to just below the rough grinding block. The rough grinding block is driven to rotate by the corresponding rotating motor 13 to perform rough grinding. During the rough grinding process, the mold to be processed is grabbed again by the loading robot arm, and placed on the corresponding placement platform 23, and the positioning and clamping are completed. After the rough grinding is completed, the cross plate 15 is rotated 90 degrees to rotate the mold to be processed to the bottom of the rough grinding block, and the mold after rough grinding is rotated to the bottom of the fine grinding block, and the rough and fine grinding treatments are carried out simultaneously. Then, the mold after fine grinding is rotated to the bottom of the polishing block, and then the grinding and polishing treatments are carried out simultaneously, so as to achieve continuous step-by-step processing. A plurality of universal adjustment components 2 are installed on the cross plate 15, and the universal adjustment components 2 include a fixed seat 21 connected to the cross plate 15, a rotating seat 22 is rotatably installed on the fixed seat 21, and a placement platform 23 is provided on the top of the rotating seat 22, and a plurality of electric push rods 24 are installed between the placement platform 23 and the rotating seat 22; Multiple electric push rods 24 are distributed in a circular array relative to the axis of the rotating seat 22. The telescopic rods of the multiple electric push rods 24 are extended together to drive the mold to rise and contact with the processing block 14, thereby achieving surface treatment of molds of different heights on the placement platform 23, further improving the application scope of the device, and combining with the contraction movement of the telescopic rod of a single electric push rod 24, the inclination angle of the placement platform 23 can be adjusted, and combined with the rotation of the rotating seat 22, high-quality surface treatment of the mold at multiple angles can be achieved.

[0021] A clamping and positioning assembly 3 for fixing the mold is provided on the placement platform 23. The clamping and positioning assembly 3 includes two groups of semicircular clamping blocks 31 and a rotating disk 32 for driving the semicircular clamping blocks 31 to move relative to or away from each other. The mold placed on the placement platform 23 is clamped and fixed through the relative movement of the two groups of semicircular clamping blocks 31.

[0022] An outer gear ring 25 is fixedly connected to the fixed seat 21, a servo motor 26 is bolted to the rotating seat 22, and a driving gear 27 meshing with the outer gear ring 25 is fixedly connected to the output shaft of the servo motor 26. The telescopic rod of the single electric push rod 24 contracts and adjusts the inclination angle of the placement platform 23. The servo motor 26 drives the rotating seat 22 to rotate with the fixed mold through the meshing driving gear 27 and the outer gear ring 25, thereby realizing the adjustment of processing surfaces at different angles, without the need for repeated clamping operations, and realizing rapid processing of multiple surfaces.

[0023] One end of the electric push rod 24 is hinged with a lower hinge seat 28 fixed to the rotating seat 22, and a U-shaped plate 29 is installed at the end of the telescopic rod of the electric push rod 24. A cross connecting block 210 is rotatably installed on the U-shaped plate 29, and an upper hinge seat 211 fixed to the placement platform 23 is hinged on the cross connecting block 210; The lower hinge seat 28 is provided to allow the electric push rod 24 to swing in bilateral directions on the rotating seat 22. The U-shaped plate 29, the cross connecting block 210 and the upper hinge seat 211 are provided to realize the universal swing between the electric push rod 24 and the placement platform 23, thereby realizing the effect of adjusting the inclination angle of the placement platform 23 when the telescopic rod of the single electric push rod 24 contracts.

[0024] A rotating groove rotatably connected to the rotating disk 32 is provided inside the placement platform 23, and four groups of movable grooves distributed in a circular array relative to the rotating disk 32 are provided on the top of the rotating groove. Movable blocks 33 are slidably connected in the movable grooves. Two groups of semicircular clamping blocks 31 are installed on the top of the two groups of relative movable blocks 33. A clamping motor 34 for driving the rotating disk 32 to rotate is installed on the bottom bolts of the placement platform 23. The rotating disk 32 is driven to rotate by the clamping motor 34, and the rotating disk 32 causes multiple movable blocks 33 to move in relative directions, thereby carrying the two groups of semicircular clamping blocks 31 to clamp and fix the mold.

[0025] Two groups of arc-shaped guide grooves 313 are provided on the top of the rotating disk 32, and an arc-shaped groove 314 is smoothly provided on the end of the arc-shaped guide groove 313 away from the axis of the rotating disk 32. A guide column 315 is fixedly connected to the movable block 33. The clamping motor 34 drives the rotating disk 32 to rotate. The guide column 315 on the semicircular clamping block 31 first slides in the arc-shaped groove 314 to temporarily limit the movement of the semicircular clamping block 31, and then prompts the guide column 315 to slide from the arc-shaped groove 314 into the arc-shaped guide groove 313, driving the two groups of semicircular clamping blocks 31 to move relative to each other, thereby completing the clamping and fixation of the mold.

[0026] Example 2: Please refer to Figure 6-Figure 9 As shown in the figure, the problem that the centering clamping cannot be achieved during the fixing process of the special-shaped mold, which easily leads to the mold position deviation and processing damage, can be solved by the following solutions: In this embodiment, two groups of semicircular blocks 1 35 are rotatably mounted on the semicircular clamping block 31, and two groups of semicircular blocks 2 36 are rotatably mounted on the semicircular block 1 35, and two groups of semicircular blocks 3 37 are rotatably mounted on the semicircular block 2 36. The two groups of semicircular clamping blocks 31 move relative to each other, so that multiple semicircular blocks 3 37 are in contact with the mold, and combined with the sliding connection between the semicircular block 3 37 and the semicircular block 2 36, the semicircular block 2 36 and the semicircular block 1 35, and the semicircular block 1 35 and the semicircular clamping block 31, the multiple semicircular blocks 3 37 are adaptively contacted with the outer wall of the mold, thereby completing the stable positioning and clamping of the mold, and further improving the stability of the mold during multi-angle processing.

[0027] Two groups of auxiliary blocks 38 are arranged between the semicircular clamping blocks 31. The auxiliary blocks 38 are mounted on a movable block 33 perpendicular to the movement direction of the semicircular clamping blocks 31. Positioning blocks 39 and support plates 310 are arranged on both sides of the auxiliary blocks 38. The two groups of positioning blocks 39 cooperate with the two groups of semicircular clamping blocks 31 to clamp the mold at multiple points, thereby realizing stable fixation of the special-shaped mold. A sliding rod 311 sliding with the auxiliary blocks 38 is fixedly connected between the positioning blocks 39 and the support plates 310. A reset tension spring 312 is fixedly connected between the support plates 310 and the auxiliary blocks 38. The positioning block 39 is prompted to flexibly clamp the mold to avoid interference with the relative movement of the semicircular clamping block 31. Before the two groups of semicircular clamping blocks 31 clamp the mold, the two groups of auxiliary blocks 38 are first prompted to carry the positioning block 39 to move, so that the positioning block 39 contacts the outer wall of the mold, and combined with the reset spring 312, the positioning block 39 flexibly clamps the mold, thereby preliminarily completing the positioning and placement of the mold, and then the multiple semicircular blocks 37 on the semicircular clamping block 31 are adaptively contacted with the outer wall of the mold, thereby realizing self-centering clamping of the special-shaped mold.

[0028] Two sets of arc-shaped guide grooves 316 are formed at the top of the rotating disk 32 and between the arc-shaped guide grooves 313. An arc-shaped guide groove 317 is formed at one end of the arc-shaped guide groove 316 close to the axis of the rotating disk 32. The clamping motor 34 drives the rotating disk 32 to rotate, and the guide column 315 on the auxiliary block 38 slides in the arc-shaped guide groove 2 316, so that the two groups of auxiliary blocks 38 carry the positioning blocks 39 to move relative to each other, so that the two groups of positioning blocks 39 first contact the outer wall of the mold, until the guide column 315 on the auxiliary block 38 slides from the arc-shaped guide groove 2 316 into the arc-shaped groove 2 317, limiting the continuous movement of the auxiliary block 38, and combining the slide bar 311 and the support plate 310 to stretch the reset tension spring 312, the mold is flexibly clamped, and the initial positioning and placement of the mold is completed; The axes of the arc groove 2 317, the arc groove 1 314 and the rotating disk 32 coincide with each other, so that when the guide post 315 on the auxiliary block 38 slides in the arc groove 2 316, the guide post 315 on the semicircular clamping block 31 slides in the arc groove 1 314, and thus the position change of the semicircular clamping block 31 is not guided, so that the positioning block 39 first contacts the mold and pushes it to move, and after the initial positioning and placement of the mold is completed, the semicircular clamping block 31 is moved; When the guide post 315 on the semicircular clamping block 31 slides in the arc guide groove 1 313, the guide post 315 on the auxiliary block 38 slides in the arc groove 2 317, restricting the auxiliary block 38 from continuing to move, thereby avoiding excessive increase in the contact force between the positioning block 39 and the mold, which may cause scratches on the mold surface during secondary positioning and clamping.

[0029] Example 3: Please refer to Figure 1-Figure 9 As shown, the present invention also proposes a mold surface treatment process based on surface treatment, comprising the following steps: Step 1: Preliminary positioning and placement of the mold. The specific steps are as follows: the mold with the surface to be polished is grabbed by the loading robot arm and placed on one of the placement platforms 23. The clamping motor 34 drives the rotating disk 32 to rotate. The guide column 315 on the auxiliary block 38 slides in the arc guide groove 2 316, prompting the two groups of auxiliary blocks 38 to carry the positioning blocks 39 to move relative to each other. The guide column 315 on the semicircular clamping block 31 slides in the arc groove 1 314 to limit the movement of the semicircular clamping block 31, prompting the two groups of positioning blocks 39 to first contact the linear outer wall of the mold, until the guide column 315 on the auxiliary block 38 slides from the arc guide groove 2 316 into the arc groove 2 317, limiting the continuous movement of the auxiliary block 38, and combining the slide bar 311 and the support plate 310 to stretch the reset tension spring 312, flexibly clamp the mold, and complete the preliminary positioning and placement of the mold; Step 2: Stable positioning and clamping of the mold, the specific steps are as follows: the guide column 315 on the semicircular clamping block 31 slides from the arc groove 1 314 into the arc guide groove 1 313, so that the two groups of semicircular clamping blocks 31 move relative to each other, so that the multiple semicircular blocks 3 37 contact the mold, and the sliding connection between the semicircular block 37 and the semicircular block 2 36, the semicircular block 2 36 and the semicircular block 1 35, and the semicircular block 1 35 and the semicircular clamping block 31 is combined to promote the multiple semicircular blocks 3 37 to adaptively contact the outer wall of the mold, thereby completing the stable positioning and clamping of the mold; Step 3: Multi-angle rough grinding, fine grinding and polishing of the mold, the specific steps are as follows: the external motor combines with the gear set to drive the cross plate 15 to rotate 90 degrees, and the positioned and clamped mold is rotated to the bottom of the rough grinding block. The telescopic rods of multiple electric push rods 24 are synchronously extended to drive the mold to move upward and contact the rough grinding block. The rough grinding block is driven to rotate by the corresponding rotating motor 13, and then the telescopic rod of the single electric push rod 24 is combined with the contraction movement of the telescopic rod to adjust the inclination angle of the placement platform 23. Then, the servo motor 26 combines with the driving gear 27 and the outer gear ring 25 to drive the rotating seat 22 to carry the fixed mold to rotate, and the electric cylinder slide module 12 drives the rotating motor 13 to move horizontally to complete the multi-angle rough grinding of the mold; During the rough grinding process, the mold to be processed is grabbed by the loading robot arm again, placed on the corresponding placement platform 23, and positioned and clamped. After the rough grinding is completed, the cross plate 15 is rotated 90° to rotate the mold to be processed directly under the rough grinding block, and the mold after rough grinding is rotated to directly under the fine grinding block, and the rough and fine grinding are performed simultaneously. The mold after fine grinding is then rotated to directly under the polishing block, and then the grinding and polishing are performed simultaneously, and the mold before and after the processing is replaced simultaneously.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
