Description

Technical Field

[0001] The present invention relates to the technical field of die grinding, and particularly relates to an isostatic latex die processing equipment and a method thereof. Background Art

[0002] An isostatic latex die is a die that forms latex materials through uniform pressure. It has the characteristics of high precision and clear details, and is suitable for industrial and handicraft production. It can produce various shapes and sizes according to requirements, has high durability and environmental friendliness, and is a flexible and diverse manufacturing tool. Die grinding is an important processing technology aimed at improving the surface finish and dimensional accuracy of dies. The grinding process mainly removes excess material through a grinding wheel to achieve the required shape and size.

[0003] After the die surface is made, uneven stress during die milling may cause deformation in some areas, forming protrusions, or tool wear, improper milling parameter settings (such as feed speed and milling depth), etc., which will all affect the surface quality and cause protrusions on the die surface. At this time, the protrusions need to be processed. However, existing equipment such as the support die surface grinding and polishing equipment disclosed in CN116872068B does not process the protrusions on the die surface during the die grinding process. When the existing technology grinds the protrusions, if the treatment is excessive or uneven, it may cause excessive wear of the grinding equipment. In addition, excessive grinding will also cause waste of time and a decline in product quality. Therefore, during the grinding process, it is necessary to precisely control the force and time to improve efficiency and extend the service life of the equipment. There is a lack of a device in the existing technology that cooperates with grinding and milling of protrusions to improve the grinding efficiency. Summary of the Invention

[0004] Aiming at the above-mentioned shortcomings of the existing technology, the present invention provides an isostatic latex die processing equipment and a method thereof, which can effectively solve the problem in the existing technology that there is no treatment for protrusions during die processing.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions:

A third spring is fixedly installed between the elevating plug and the bracket. At least one liquid flow groove is formed at a position near the lower part of the inner wall of the liquid injection pipe. A blocking block is fixedly installed in the liquid flow groove. A liquid outlet groove corresponding to the blocking block is formed in the elevating plug. When the elevating plug is not driven to lift on the inner wall of the liquid injection pipe, the liquid outlet groove is not communicated with the liquid flow groove.

[0013] Preferably, an annular connection cover is fixedly installed on the upper end surface of the connection disk. A lifting ring plate is slidably installed in the connection disk. A sand plate is fixedly installed on the lower end surface of the lifting ring plate. A plurality of rubber connection columns are fixedly installed between the lifting ring plate and the annular connection cover. A plurality of installation blocks are fixedly installed at the inner top end of the annular connection cover. A third electromagnet is fixedly installed on the lower end surface of the installation block. The third electromagnet is magnetically matched with the upper end surface of the lifting ring plate. A sealing sliding plate is fixedly installed on the upper end surface of the lifting ring plate. The sealing sliding plate penetrates through the connection disk and extends above it. A swinging rod is fixedly installed on the outer wall of the lifting ring plate. One end of the third electromagnet penetrates through the connection disk and symmetrically installs two magnetic electrical contacts. Two conductive blocks are symmetrically installed on the outer wall of the connection disk. The two conductive blocks are electrically connected to the controller.

[0014] Preferably, the milling component further includes a second lifting rod sleeved on the output end of the lifting device. A second rotary driving member is fixedly installed at a position on the upper end surface of the second lifting rod and away from the lifting device. The second rotary driving member is electrically connected to the controller. The output end of the second rotary driving member penetrates through the second lifting rod and is fixedly connected to a transmission shaft. A milling cutter is fixedly installed at the lower end of the transmission shaft. Two external connecting rods are symmetrically installed at positions on both sides of the second lifting rod and away from the lifting device. A color sensor and a lighting lamp are respectively fixedly installed at the lower ends of the two external connecting rods. The color sensor is electrically connected to the controller.

[0015] Preferably, an installation table is fixedly installed at the output end of the two-dimensional driving device. Two screw rods are symmetrically installed in the installation table in a threaded manner. A clamping plate is fixedly installed at the opposite ends of the two screw rods.

[0016] Preferably, an installation frame is fixedly installed on the upper end surface of the workbench and between the lifting device and the two-dimensional driving device. An air inlet pipe is communicated with one side of the installation frame close to the lifting device. A nozzle is communicated with one side of the installation frame close to the two-dimensional driving device. The air inlet pipe is communicated with the nozzle. The installation frame is externally connected to a jetting device.

[0017] A method for an isostatic latex mold processing device includes the following steps:

[0018] S1. Fix the workpiece to be processed through the upper end surface of the clamping and cleaning component;

[0019] S2. Drive the connection disk and the grinding sheet to descend through the lifting device to grind the surface of the workpiece. During the grinding process, the balls will contact the protrusions on the surface of the workpiece and spray a marking liquid for marking;

[0020] S3. After marking the protrusions, drive the milling component to descend through the lifting device, and mill the protrusions through the milling component;

[0021] S4. After the grinding disc and the grinding piece finish grinding and the milling cutter finishes cutting the protrusion, the workpiece will return along the previous grinding route, allowing the connecting disc and the grinding piece to re-grind the cutting area, and adjusting the downward pressure during grinding according to the roughness cut out.

[0022] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art:

[0023] First, by setting the grinding assembly, the connecting disc and the grinding piece cooperate with the milling cutter set in the milling assembly to grind and mill the mold. During the grinding process, the mold can be comprehensively ground. When there are protrusion defects on the surface of the mold, the milling cutter can be used to mill the protrusion to remove the protrusion, thereby improving the efficiency of grinding and milling, reducing the time for separate grinding and milling operations, and providing a device that cooperates with grinding and milling of the protrusion to improve the grinding efficiency.

[0024] Second, through the setting of the lifting plug, when the first grinding encounters a protrusion on the surface of the mold, the ball will contact the protrusion and drive the lifting plug to lift and lower in the liquid injection pipe to make the liquid outlet groove coincide with the liquid flow groove so that the marking liquid sprays out (under a certain liquid pressure) for marking. At the same time, when encountering a depression on the surface of the mold, the ball will drive the lifting plug to slide at the depression to make the marking liquid spray out for marking the depression. Each time the depression is marked, the counter will be triggered to count, and the counting range is set. When the counting range is exceeded, it can be displayed through the controller.

[0025] Third, after the first grinding and milling are completed, the second grinding is carried out to grind the position of the milling. During the grinding process, the sand plate can detect the processing marks or minute unevenness at the cutting area, and adjust the first electromagnet and the second electromagnet to increase the magnetic repulsion force under the original repulsive property, driving the grinding piece to increase the pressure applied to the cutting area of the mold and carry out grinding. After grinding smoothly, the sand plate is reset to its original position by the elastic force of the rubber connecting column to further grind the cutting area and ensure the smoothness of the surface of the mold.

Detailed implementation manners

[0037] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] The present invention will be further described below with reference to the embodiments.

[0039] Embodiment: Refer to Figures 1 to 9 , an isostatic latex mold processing device, comprising:

[0040] A workbench 1, on the upper end surface of the workbench 1, two lifting devices 2 and a two-dimensional driving device 3 are fixedly installed. The lifting device 2 and the two-dimensional driving device 3 are connected to a controller. The lifting device 2 can be used with a linear actuator. The basic working principle of the linear actuator is to convert the input rotational motion (from a motor or other power source) into a linear motion through a mechanical transmission system (such as a lead screw or a belt). The two-dimensional driving device 3 usually has two linear actuators to control the movement of the X-axis and the Y-axis respectively. By coordinating the movements in these two directions, precise positioning at any position can be achieved. The motion control system calculates the required positions and speeds of each actuator according to the preset path, thereby achieving smooth movement;

[0041] A grinding assembly 4, which 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. The grinding assembly 4 includes a liquid injection pipe 409. A connecting disk 414 is fixedly installed on the lower end surface of the liquid injection pipe 409. A grinding disc 430 is fixedly installed on the lower end surface of the connecting disk 414. An elevating plug 413 is elastically slidably installed at a position near the lower part of the inner wall of the liquid injection pipe 409. A ball is rotatably installed at the lower end of the elevating plug 413. A liquid injection cavity is formed between the inner wall of the liquid injection pipe 409 and the elevating plug 413. An elevating pressing plate 411 is elastically slidably installed in the liquid injection cavity. A marking liquid is filled between the elevating pressing plate 411 and the elevating plug 413. The marking liquid can be used with edible pigment. This kind of edible pigment is non-toxic and harmless and is easy to remove. At the same time, in terms of the selected color, a color with contrast to the mold color can be selected for use;

[0042] A milling assembly 5, which is used to detect the protrusions on the surface of the workpiece and mill them;

[0043] A clamping and cleaning assembly 6, which is used to clamp the workpiece.

[0044] Refer to Figures 2 to 3, a first lifting rod 401 is sleeved on the driving end of the lifting device 2. At a position on the upper end surface of the first lifting rod 401 and far from the lifting device 2, a first rotary driving member 402 is fixedly installed. The first rotary driving member 402 is electrically connected to a controller. The rotating end of the first rotary driving member 402 penetrates through the first lifting rod 401 and a rotating shaft 403 is fixedly installed. A sliding block is integrally formed on the lower end surface of the rotating shaft 403. A sliding box 404 is slidably installed on the outer side surface of the sliding block. A first spring 407 is fixedly installed between the sliding block and the inner bottom end of the sliding box 404. A connecting shaft 408 is fixedly installed on the lower end surface of the sliding box 404. The lower end surface of the connecting shaft 408 is fixed to the liquid injection pipe 409. A second spring 410 is fixedly installed between the upper end surface of the lifting pressing plate 411 and the inner wall of the liquid injection pipe 409. A plug-in valve 412 is fixedly installed on the outer wall of the liquid injection pipe 409. The marking liquid can be injected into the interior of the liquid injection cavity through the plug-in valve 412. When injecting into the interior of the liquid injection cavity, the marking liquid will squeeze the lifting pressing plate 411 and compress the second spring 410. In this way, when the marking liquid sprays outwards from the liquid injection cavity, through the extrusion of the lifting pressing plate 411, the marking liquid will have a certain liquid pressure.

[0045] Refer to Figures 5 to 7 , a bracket 415 is fixedly installed at a position near the lower part of the inner wall of the liquid injection pipe 409. A trigger sensor 416 is fixedly installed on the upper end surface of the bracket 415. The trigger sensor 416 is signal-connected to an alarm through a controller. The detection end of the trigger sensor 416 penetrates 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 a position near the lower part of the inner wall of the liquid injection pipe 409. A blocking block 418 is fixedly installed in the liquid flow groove 417. A liquid outlet groove 419 corresponding to the blocking block 418 is opened in the lifting plug 413. When the lifting plug 413 is not driven to lift and lower on the inner wall of the liquid injection pipe 409, the liquid outlet groove 419 is not communicated with the liquid flow groove 417. Through the setting of the blocking block 418, when the lifting plug 413 is not driven to lift and lower, the liquid outlet groove 419 is blocked by the blocking block 418 and is not communicated with the liquid flow groove 417. During the process of the lifting plug 413 being driven to lift and lower, the liquid outlet groove 419 will be communicated with the liquid flow groove 417 whether it rises or falls.

[0046] Refer to Figures 6 to 8, an annular connection cover 420 is fixedly installed on the upper end surface of the connection plate 414. A lifting ring plate 422 is slidably installed in the connection plate 414. A sand plate 425 is fixedly installed on the lower end surface of the lifting ring plate 422. A plurality of rubber connection columns 421 are fixedly installed between the lifting ring plate 422 and the annular connection cover 420. A plurality of mounting blocks 423 are fixedly installed at the inner top end of the annular connection cover 420. A third electromagnet 424 is fixedly installed on the lower end surface of the mounting block 423. The third electromagnet 424 is magnetically matched with the upper end surface of the lifting ring plate 422. A sealing slide plate 428 is fixedly installed on the upper end surface of the lifting ring plate 422. The sealing slide plate 428 penetrates through the connection plate 414 and extends above it. A swing rod 426 is fixedly installed on the outer wall of the lifting ring plate 422. One end of the third electromagnet 424 penetrates through the connection plate 414 and symmetrically installs two magnetic electric contacts 427. Two conductive blocks 429 are symmetrically installed on the outer wall of the connection plate 414. The two conductive blocks 429 are electrically connected to the controller. The third electromagnet 424 installed on the lower end surface of the mounting block 423 can adsorb the lifting ring plate 422, making the lifting ring plate 422 drive the sand plate 425 to form a height difference with the lower end surface of the grinding sheet 430 on the inner wall of the connection plate 414. During the second grinding, the controller will disconnect the power supply delivered to the third electromagnet 424, making the third electromagnet 424 stop magnetically connecting with the lifting ring plate 422, and making the lifting ring plate 422 drive the sand plate 425 to slide downward, making the lower end surface of the sand plate 425 flush with the lower end surface of the grinding sheet 430.

[0047] Refer to Figure 2 , the milling component 5 further includes a second lifting rod 501 sleeved on the output end of the lifting device 2. A second rotary driving member 502 is fixedly installed at a position on the upper end surface of the second lifting rod 501 and far from the lifting device 2. The second rotary driving member 502 is electrically connected to the controller. The output end of the second rotary driving member 502 penetrates through the second lifting rod 501 and is fixedly connected to a transmission shaft 503. A milling cutter 507 is fixedly installed at the lower end of the transmission shaft 503. Two external connecting rods 504 are symmetrically installed on both sides of the second lifting rod 501 and far from the lifting device 2. A color sensor 505 and a lighting lamp 506 are respectively fixedly installed at the lower ends of the two external connecting rods 504. The color sensor 505 is electrically connected to the controller. The color sensor 505 generally consists of a light source, a photodetector, and a signal processing circuit. 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.

[0048] Refer to Figure 9, a mounting table 601 is fixedly installed at the output end of the two-dimensional driving device 3. Two screw rods 602 are symmetrically and threadedly installed in the mounting table 601. A clamping plate 603 is fixedly installed at the opposite ends 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. An air inlet pipe 605 is communicated with one side of the mounting frame 604 close to the lifting device 2. A nozzle 606 is communicated with one side of the mounting frame 604 close to the two-dimensional driving device 3. The air inlet pipe 605 is communicated with the nozzle 606. The mounting frame 604 is externally connected to a jetting device. The air inlet pipe 605 is connected through an externally connected jetting device (the jetting device can be used with an air pump and a jet pipe). After the grinding is completed, the mounting table 601 can be jetted to remove the residues of grinding and milling.

[0049] The basic concept of the present invention is as follows:

[0050] 1. Set a threshold value for the number of depressions 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 marked number is greater than the threshold value of the set marked number, it is determined as a non-conforming product and no further processing is carried out; 3. If the marked number is less than the threshold value of the set number, it is determined as a qualified product. If there are protrusions, the protrusions can be ground, and after grinding, a second grinding is carried out for the milling part of the protrusions.

[0051] The working principle of the present invention is as follows:

[0052] Place the mold to be processed on the upper end of the mounting table 601, and twist the screw rod 602 to make the two clamping plates 603 move relatively to clamp and fix the mold (an isostatic latex mold is provided on the mounting table 601, such as Figure 1As shown, the dashed part is a latex sleeve used in conjunction with the processed isostatic pressing mold). Through the settings of the two-dimensional drive device 3 and the lifting device 2, the two-dimensional drive 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 by the lifting device 2 to descend. The descending first lifting rod 401 drives the connecting disk 414 and the grinding disk 430 to descend and contact the surface of the mold. By turning on the first rotary drive member 402, the rotating shaft 403, the sliding box 404, the connecting shaft 408, and the liquid injection pipe 409 are driven to rotate, so that the connecting disk 414 and the grinding disk 430 rotate to grind the surface of the mold (during the grinding process, the two-dimensional drive device 3 continuously drives the mold to rotate, so that the connecting disk 414 and the grinding disk 430 perform circumferential grinding on the surface of the mold. At the same time, when the two-dimensional drive device 3 drives the mold to rotate, it will continuously drive the mold to perform linear movement to ensure that the grinding disk 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 liquid injection pipe 409 and compress the third spring 431, so that the liquid outlet groove 419 coincides with the liquid flow groove 417 (during the lifting and lowering process of the lifting plug 413, the liquid outlet groove 419 and the liquid flow groove 417 will not immediately coincide to spray the marking liquid to mark the protrusions and depressions. The lifting and lowering amplitude of the lifting plug 413 allows the depressions and protrusions to exist within a certain range (see appendix Figure 7 ), when exceeding the range, the liquid outlet groove 419 will communicate with the liquid flow groove 417 for marking), so that the marking liquid in the liquid injection cavity is sprayed from the lower end of the lifting plug 413 through the liquid outlet groove 419 to mark the protrusion. When encountering a depression on the surface of the mold, the ball will also drive the lifting plug 413 to slide down on the inner wall of the liquid injection pipe 409, so that the liquid outlet groove 419 slides downward at the inner wall of the stopper 418 and coincides with the liquid flow groove 417, and the marking liquid is sprayed to mark the depression. Each time when encountering a protrusion or a depression, the sensor 416 will be triggered during the sliding process of the lifting plug 413. The quantity threshold triggered by the depression can be set according to the usage requirements of the mold. When the marking exceeds the set quantity, the triggered sensor 416 will transmit a signal to the controller for counting, and when it exceeds the set counting range, an alarm will be connected to give an alarm, and the mold will be determined to be scrapped;

[0053] After marking the protrusion, the second lifting rod 501 is driven to move by the lifting device 2. There is a spacing 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 will detect the marking liquid at the marked position. After detecting the marking liquid, it will transmit a signal to the controller, and the controller will transmit a signal to turn on the second rotary driving member 502 to drive the transmission shaft 503 and the milling cutter 507 to rotate, and the milling cutter 507 will mill the protrusion at the marked position;

[0054] After the lifting plug 413 and the grinding disc 430 finish grinding the surface of the mold and the milling cutter 507 finishes 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 during the first grinding. At this time, the surface of the mold has been ground for the first time and has a certain smoothness. Before the second grinding, the controller will send a signal to cut off the power supply of the third electromagnet 424, disconnect the magnetic connection between the third electromagnet 424 and the lifting ring plate 422, and let the lifting ring plate 422 slide down along the inner wall of the connecting plate 414, making the lower end surface of the sand plate 425 flush with the lower end surface of the grinding disc 430. During the second grinding of the mold by the grinding disc 430 (the second grinding is mainly for the cutting area. Although milling can remove large defects, it may leave machining marks or minute unevenness. Therefore, grinding the cutting area is necessary to improve the surface smoothness and visual effect), the sand plate 425 will synchronously grind the moving mold with the grinding disc 430. When moving to the cutting area, the machining marks or minute unevenness will contact both the grinding disc 430 and the sand plate 425. At this time, during the rotation of the sand plate 425 along with the connecting plate 414, it will contact the machining marks or minute unevenness and be subject to resistance. The sand plate 425 subject to resistance will rotate within 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 electrical contact 427 to rotate, and the magnetic electrical contact 427 will contact the conducting block 429 to conduct electricity. After conducting electricity, the conducting block 429 will transmit a signal through connection with the controller to control the magnetic force of the second electromagnet 406 to increase, causing the first electromagnet 405 and the second electromagnet 406 arranged in the sliding box 404 to increase the magnetic repulsion force on the basis of the original repulsion. The magnetic repulsion force is proportional to the resistance received by the sand plate 425. The increased repulsion will cause the sliding box 404 to slide downward on the outer side of the sliding block. The downward-sliding sliding box 404 will drive the connecting plate 414 and the grinding disc 430 to apply downward pressure through the connecting shaft 408 and the liquid injection pipe 409, so that the grinding disc 430 applies pressure to the cutting area of the mold and conducts grinding. After completely grinding the machining marks or minute unevenness in the cutting area, the sand plate 425 and the rubber connecting column 421 will reset to their original positions by elastic force, causing the magnetic electrical contact 427 to disconnect the electrical connection with the conducting block 429, and the first electromagnet 405 and the second electromagnet 406 to resume their original repulsion. Repeat the above actions to perform secondary grinding on the cutting area.
