Description

Technical Field

[0001] The invention relates to the technical field of mold grinding, and in particular to isostatic latex mold processing equipment and a method thereof. Background Art

[0002] Isostatic latex molds are molds that shape latex materials through uniform pressure. They are characterized by high precision and clear details. They are suitable for industrial and handicraft production. They can be made into various shapes and sizes according to needs. They are highly durable and environmentally friendly and are flexible and diverse manufacturing tools. Mold grinding is an important processing technology that aims to improve the surface finish and dimensional accuracy of the mold. The grinding process mainly removes excess material through a grinding wheel to achieve the desired shape and size.

[0003] After the mold surface is made, uneven force during mold milling may cause deformation of certain areas, forming protrusions, or tool wear, improper milling parameter settings (such as feed speed and milling depth), etc., will affect the surface quality and cause protrusions on the mold surface. At this time, the protrusions need to be processed. However, existing equipment, such as the support mold surface grinding and polishing equipment disclosed in publication number CN116872068B, does not process the protrusions on the mold surface during the grinding of the mold. When the prior art grinds the protrusions, if the protrusions are excessively or unevenly processed, it may cause excessive wear of the grinding equipment. In addition, excessive grinding will also cause time waste and reduced product quality.

The two-dimensional drive device 3 usually has two linear drives to control the movement of the X-axis and the Y-axis respectively. By coordinating the movement of these two directions, precise positioning at any position can be achieved. The motion control system calculates the required position and speed of each drive according to a preset path, thereby achieving smooth movement; The grinding component 4 is driven by the lifting device 2 to lift on the upper end surface of the workbench 1 and grind the workpiece while marking the protrusions on the surface of the workpiece.

A second spring 410 is fixedly installed between the upper end surface of the lifting and pressure plate 411 and the inner wall of the injection tube 409. A plug-in valve 412 is fixedly installed on the outer wall of the injection tube 409. The marking liquid can be injected into the interior of the injection cavity through the plug-in valve 412. When injected into the interior of the injection cavity, the marking liquid will squeeze the lifting and pressure plate 411 and compress the second spring 410. In this way, when the marking liquid is sprayed out of the injection cavity, it will have a certain liquid pressure through the squeezing of the lifting and pressure plate 411.

[0023] Reference Figures 5 to 7 A bracket 415 is fixedly installed at the lower position of the inner wall of the injection tube 409, and a trigger sensor 416 is fixedly installed on the upper end surface of the bracket 415. The trigger sensor 416 is connected to the alarm through a controller signal. The detection end of the trigger sensor 416 passes through the bracket 415 and contacts the upper end surface of the lifting plug 413. A third spring 431 is fixedly installed between the lifting plug 413 and the bracket 415. At least one liquid flow groove 417 is opened at the lower position of the inner wall of the injection tube 409, and a stopper 431 is fixedly installed in the liquid flow groove 417. 18. A liquid outlet groove 419 corresponding to the stopper 418 is provided in the lifting plug 413. When the lifting plug 413 is not driven to lift on the inner wall of the injection tube 409, the liquid outlet groove 419 is not in communication with the liquid flow groove 417. By setting the stopper 418, when the lifting plug 413 is not driven to lift, the liquid outlet groove 419 is not in communication with the liquid flow groove 417 due to the obstruction of the stopper 418. When the lifting plug 413 is driven to lift, the liquid outlet groove 419 will flow with the liquid flow groove 417 regardless of whether it is rising or falling.

The third electromagnet 424 installed on the lower end surface of the mounting block 423 can adsorb the lifting ring plate 422, so that the lifting ring plate 422 drives the sanding plate 425 and the lower end surface of the grinding sheet 430 to form a height difference on the inner wall of the connecting disk 414. During the second grinding, the controller will disconnect the power supply to the third electromagnet 424, so that the third electromagnet 424 stops the magnetic connection with the lifting ring plate 422, and allows the lifting ring plate 422 to drive the sanding plate 425 to slide downward, so that the lower end surface of the sanding plate 425 is flush with the lower end surface of the grinding sheet 430.

When the light source irradiates the object to be measured, the object will reflect light of a certain wavelength, and the color is judged by detecting the reflected light.

[0026] Reference Fig. 9A mounting platform 601 is fixedly installed at the output end of the two-dimensional driving device 3, and two screw rods 602 are symmetrically threadedly installed in the mounting platform 601, and a clamping plate 603 is fixedly installed at the opposite end of the two screw rods 602. A mounting frame 604 is fixedly installed on the upper end surface of the workbench 1 and between the lifting device 2 and the two-dimensional driving device 3. The side of the mounting frame 604 close to the lifting device 2 is connected with an air intake pipe 605, and the side of the mounting frame 604 close to the two-dimensional driving device 3 is connected with a nozzle 606, and the air intake pipe 605 is connected to the nozzle 606. The mounting frame 604 is externally connected to a jet device, and the air intake pipe 605 is connected through the external jet device (the jet device can be used with an air pump and a jet tube). After grinding, the mounting platform 601 can be sprayed to remove grinding and milling residues.

[0027] The basic concept of the present invention is as follows: 1. Set the depression number threshold to determine whether the mold meets the standard of qualified products; 2. During the first comprehensive grinding process, mark and count the protrusions and depressions. If the number of marks is greater than the set threshold, it is judged as a defective product and no longer processed; 3. If the number of marks is less than the set threshold, it is judged as a qualified product. If there are protrusions, the protrusions can be ground, and after grinding, the milling part of the protrusion can be ground for the second time.

[0028] The working principle of the present invention is as follows: Place the mold to be processed on the upper end of the mounting table 601, twist the screw 602 to make the two clamping plates 603 move relative to each other to clamp and fix the mold (an isostatic latex mold is set on the mounting table 601, such as Figure 1As shown, the dotted part is a latex sleeve used in conjunction with the processed isostatic pressing mold). Through the setting of the two-dimensional driving device 3 and the lifting device 2, the two-dimensional driving device 3 and the lifting device 2 can be externally controlled and programmed according to the height and thickness of the mold, so as to ensure that the grinding component 4 and the milling component 5 can grind and mill the surface of the mold according to the height and thickness of the mold. The first lifting rod 401 is driven to descend by the lifting device 2. The descending first lifting rod 401 will drive the connecting plate 414 and the grinding sheet 430 to descend and contact the surface of the mold. By opening the first rotating driving member 402, the rotating shaft 403, the sliding box 404, the connecting shaft 408 and the injection tube 409 are driven to rotate, so that the connecting plate 414 and the grinding sheet 430 are rotated to grind the surface of the mold (during the grinding). During the process, the two-dimensional driving device 3 continuously drives the mold to rotate, allowing the connecting disk 414 and the grinding sheet 430 to grind the circumference of the surface of the mold. At the same time, the two-dimensional driving device 3 drives the mold to rotate and continuously drives the mold to move linearly to ensure that the grinding sheet 430 can grind the entire surface of the mold). During the grinding process, if the ball contacts the protrusion on the surface of the mold, the ball will drive the lifting plug 413 to slide on the inner wall of the injection tube 409 and compress the third spring 431, so that the liquid outlet groove 419 and the liquid flow groove 417 overlap (in the process of the lifting plug 413 being lifted and lowered, the liquid outlet groove 419 and the liquid flow groove 417 will not overlap immediately). The marking liquid is sprayed to mark the protrusions and depressions. The lifting and lowering range of the lifting plug 413 allows the depressions and protrusions to exist within a certain range (see attached Figure 7 ), if the range is exceeded, the liquid outlet groove 419 will be connected to the liquid flow groove 417 for marking), so that the marking liquid in the injection cavity will be sprayed out from the lower end of the lifting plug 413 through the liquid outlet groove 419 to mark the protrusion, and when encountering a depression on the mold surface, the ball will also drive the lifting plug 413 to slide down on the inner wall of the injection tube 409, so that the liquid outlet groove 419 slides down at the inner wall of the stopper 418 and overlaps with the liquid flow groove 417, so that the marking liquid is sprayed out to mark the depression. Every time a protrusion or depression is encountered, the lifting plug 413 will trigger the sensor 416 during the sliding process. The number threshold of the depression trigger can be set according to the mold use requirements. When the mark exceeds the set number, the trigger sensor 416 will transmit a signal to the controller for counting, and after exceeding the set counting range, the alarm will be connected to alarm, and the mold will be judged as scrapped; After the protrusion is marked, the second lifting rod 501 is driven to move by the lifting device 2. There is a gap between the second lifting rod 501 and the first lifting rod 401. When the first lifting rod 401 is driven to move, the second lifting rod 501 will be driven to move accordingly. After the lifting plug 413 is marked, the second lifting rod 501 drives the transmission shaft 503 and the milling cutter 507 to move. The moving path of the milling cutter 507 on the mold surface is the same as that of the connecting plate 414. During the movement, the lighting lamp 506 and the color sensor 505 are synchronously turned on for lighting and detection. The color sensor 505 detects the marking liquid at the marked location. After detecting the marking liquid, it transmits a signal to the controller, and the controller transmits a signal to turn on the second rotating drive member 502 to drive the transmission shaft 503 and the milling cutter 507 to rotate, and the milling cutter 507 mills the protrusion at the marked location. After the lifting plug 413 and the grinding sheet 430 have finished grinding the surface of the mold and the milling cutter 507 has finished milling the protrusions, one of the lifting devices 2 will drive the milling cutter 507 to reset, and the two-dimensional driving device 3 will drive the mold to move again along the path of the first grinding. At this time, the surface of the mold has a certain degree of smoothness after the first grinding. Before the second grinding, the controller will send a signal to cut off the power supply of the third electromagnet 424, so that the magnetic connection between the third electromagnet 424 and the lifting ring plate 422 is disconnected, and the lifting ring plate 422 is allowed to slide downward on the inner wall of the connecting plate 414, so that the sand plate 425 The lower end surface is flush with the lower end surface of the grinding sheet 430. During the second grinding of the mold by the grinding sheet 430 (the second grinding is mainly for the grinding of the cutting part. Although milling can remove larger defects, it may leave processing marks or tiny unevenness. Therefore, it is necessary to grind the cutting part to improve the surface smoothness and visual effect), the sanding plate 425 will grind the moving mold synchronously with the grinding sheet 430. When moving to the cutting part, the processing marks or tiny unevenness will contact the grinding sheet 430 and the sanding plate 425. At this time, the sanding plate 425 will contact the cutting part during the rotation of the connecting plate 414. The sand plate 425 subjected to resistance will rotate in the connecting plate 414 and pull the rubber connecting column 421. The rotating sand plate 425 will drive the swing rod 426 and the magnetic electric contact 427 to rotate, and the magnetic electric contact 427 will contact the conductive block 429 to conduct electricity. The conductive block 429 after conduction will increase the magnetic force of the second electromagnet 406 by connecting to the controller and transmitting signals, so that the first electromagnet 405 and the second electromagnet 406 arranged in the sliding box 404 will increase the magnetic repulsion under the original repulsion. The magnetic repulsion is proportional to the resistance encountered by the sand plate 425. The increased repulsion will cause The sliding box 404 slides downward on the outer side of the sliding block. The sliding box 404 sliding downward will drive the connecting plate 414 and the grinding sheet 430 to apply pressure downward through the connecting shaft 408 and the injection tube 409, so that the grinding sheet 430 applies pressure to the cut part of the mold and grinds it. After the processing marks or minor unevenness of the cut part are completely polished, the sanding plate 425 and the elastic force of the rubber connecting column 421 are reset to the original position, and the magnetic electrical contact 427 is electrically disconnected from the conductive block 429, and the first electromagnet 405 and the second electromagnet 406 restore their original repulsion, and repeat the above actions to perform secondary grinding on the cut part.
