Description
Technical Field
[0001] The present invention relates to the field of 3D printing technology, and in particular to an additive manufacturing device for producing plastic parts. Background Art
[0002] Additive manufacturing equipment, also known as 3D printing, is based on additive manufacturing technology. It directly creates three-dimensional physical products by adding materials layer by layer. Its technical principle is based on a discrete, stacked digital drive method. It processes 3D model data in layers and uses laser beams, hot melt nozzles, and other methods to precisely control material deposition and formation, ultimately completing the overall manufacture of complex structures. In the production of plastic parts, 3D printing equipment is required for three-dimensional printing.
[0003] However, when traditional 3D printing equipment prints models, most of them print directly on the table top or install the placement plate before printing. Printing directly on the table top can easily cause wear of the table top. The placement plate needs to be fixed with accessories such as bolts and clamps. When it needs to be replaced later, the operation is more troublesome. If it is slightly loose, it will affect the printing quality. In addition, it is not convenient to disassemble after printing. Tools such as scrapers need to be used for scraping. The operation is very inconvenient, time-consuming and labor-intensive, and it is easy to cause wear of the table top, which also reduces the overall production efficiency. At the same time, after the model is printed, there is a lack of heat dissipation components, which causes slow heat dissipation of the model. It is easy to get burned or cause the model to deform when removing the mold, affecting the quality of the product. Summary of the Invention

DETAILED DESCRIPTION
[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the additive manufacturing equipment for plastic parts production described in the present invention includes a printer 1, and the printer 1 is connected to a table panel 2, and a placement mechanism 3 is installed on the table panel 2. The placement mechanism 3 includes a fixed plate 301, and the table panel 2 is fixedly connected to the fixed plate 301. The fixed plate 301 is connected to the placement plate 302 by a mounting groove 305, and the placement plate 302 is installed with a blanking mechanism 5.
[0023] Specifically, such as Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, the unloading mechanism 5 includes a movable groove 504, and the placing plate 302 is provided with a plurality of equally distributed movable grooves 504, and a plurality of slide plates 501 are slidably connected inside the plurality of movable grooves 504, and a plurality of connecting springs 506 are connected between the bottom of the slide plate 501 and the bottom of the movable groove 504. A plurality of equally distributed fixed shafts 502 are fixedly connected inside the placing plate 302, and the plurality of fixed shafts 502 are respectively perpendicularly distributed to the plurality of movable grooves 504, and the fixed shafts 502 extend into the movable groove 504, and a plurality of top blocks 505 are respectively installed at the bottom of the plurality of slide plates 501, and the top blocks 505 are located on one side of the fixed shaft 502. The opening of the plurality of movable grooves 504 facilitates the installation of the plurality of slide plates 501, and the support of the plurality of connecting springs 506 enables the tops of the plurality of slide plates 501 to be aligned with the placing plate 302. The top of the plate 302 is flush, which facilitates the stable placement of the model during printing. The installation of multiple fixed shafts 502 is conducive to supporting the bottom of multiple slides 501 to prevent the slides 501 from sliding down. The installation of multiple top blocks 505 allows the slides 501 to be pulled synchronously, and the slides 501 will get rid of the elastic force of the connecting springs 506 and slide to a certain position, so that the tops of the multiple slides 501 are separated from the bottom of the model. Then, when the slides 501 continue to slide, the top block 505 at the bottom of the slide 501 collides with the fixed shaft 502, and the fixed shaft 502 rises against the top rod 405, so that the top block 505 drives the slide 501 to get rid of the elastic force of the connecting spring 506 and slide upward, which is conducive to lifting the model, separating the bottom of the model from the placement plate 302, and realizing model demoulding and removal, which is convenient to operate.
[0024] Specifically, such as Figure 6 、 Figure 7 and Figure 8As shown, the top block 505 is a trapezoidal structure, and multiple fixed shafts 502 are rotatably connected to rollers 503, and the rollers 503 are located inside the movable grooves 504. Multiple top blocks 505 respectively conflict with the rollers 503, and one end of multiple slides 501 is fixedly connected with guide blocks 507, and the guide blocks 507 are trapezoidal structures. The guide blocks 507 are slidably connected to the inside of the placement plate 302. Through the installation of multiple rollers 503, the top block 505 is facilitated to be lifted more smoothly after conflicting with the rollers 503, playing a unidirectional and friction-reducing role. Through the installation of the guide blocks 507, the slide 501 is positioned, so that the slide 501 cannot slide upward, thereby ensuring the stability of the slide 501. After the slide 501 slides to a certain position, the guide blocks 507 will allow the slide 501 to slide obliquely upward.
[0025] Specifically, such as Figure 6 、 Figure 8 and Figure 9 As shown, the placement plate 302 is internally installed with a drive mechanism 6, and the drive mechanism 6 includes a drive shaft 601. The placement plate 302 is internally rotatably connected to the drive shaft 601 at one end, and the drive shaft 601 passes through multiple movable slots 504. A plurality of equidistantly distributed cams 602 are fixedly connected to the drive shaft 601. The slide 501 is a "7"-shaped structure, and the plurality of cams 602 respectively contact the inner wall of the end of the slide 501. Two reducers 603 are respectively installed inside one end of the placement plate 302, and the two reducers 603 are respectively installed with drive motors 604. The drive shaft 60 The two ends of the drive shaft 601 are respectively connected to the inside of the two reducers 603. The installation of the drive shaft 601 facilitates the connection of the multiple cams 602. The cooperation of the two reducers 603 and the drive motor 604 realizes the control of the rotation of the drive shaft 601. The drive shaft 601 drives the multiple cams 602 to resist the multiple slides 501, so that the multiple slides 501 can slide and then push upward to realize the separation work of the model. The installation of the reducer 603 makes the rotation speed of the drive shaft 601 slow and the torque large, which is conducive to better driving the slides 501 to be demoulded.
[0026] Specifically, such as Figure 2 and Figure 10As shown, two symmetrical handles 303 are vertically connected to the top edge of the placement plate 302. The length of the placement plate 302 is less than the length of the mounting slot 305. A rubber pad 307 is installed at the bottom of the mounting slot 305. The bottom of the placement plate 302 is in conflict with the rubber pad 307. The installation of the two handles 303 facilitates the grasping and lifting of the placement plate 302, and facilitates the disassembly and assembly of the placement plate 302 and the mounting slot 305, and the installation is smoother and more convenient. Through the installation of the rubber pad 307, since the rubber pad 307 has a certain elasticity, it has a conflicting effect on the bottom of the placement plate 302, so that the placement plate 302 is stably installed and will not loosen.
[0027] Specifically, such as Figure 3 and Figure 4 As shown, a support block 304 is installed inside one end of the fixed plate 301, and the support block 304 is slidably connected to the inside of the fixed plate 301 through a plurality of interference springs 306. One end of the support block 304 extends to the inside of the installation slot 305 and interferes with the placement plate 302. The support block 304 is a "convex" shaped structure, and is inserted into the inside of the installation slot 305 through the placement plate 302. The placement plate 302 will interfere with the support block 304, and the support block 304 will break away from the elastic force of the interference spring 306 and contract, so that the placement plate 302 can be engaged with the inside of the installation slot 305 after sliding to a certain position. After the placement plate 302 is stably installed, the support block 304 is in contact with the placement plate 302 under the interference of the interference spring 306, and the placement plate 302 is firmly engaged with the inside of the installation slot 305 and will not loosen.
[0028] Specifically, such as Figure 2 、 Figure 3 、 Figure 10 and Figure 11As shown, a plurality of locking mechanisms 4 are installed inside the fixing plate 301, and the locking mechanism 4 includes a card slot 403. The center lines of the four sides of the placement plate 302 are respectively provided with a card slot 403. Two bayonet pins 402 are respectively installed inside the two ends of the fixing plate 301. The two symmetrical bayonet pins 402 form a group. The bayonet pins 402 are in a "7" shape. The bayonet pins 402 are slidably connected to the inside of the fixing plate 301 through a plurality of return springs 404. The top end of the bayonet pin 402 extends to the mounting slot. The interior of 305 engages with the card slot 403, and two drive blocks 401 are fixedly installed on both sides of one end of the printer 1. The drive block 401 is a trapezoidal structure, and one side of the bottom of the latch 402 has a certain slope. Two push rods 405 are installed inside the two ends of the fixed plate 301. The two groups of push rods 405 are slidably connected to the interior of the fixed plate 301 through compression springs 407. The upper and lower ends of the push rods 405 are rotatably connected to two guide wheels 406. The top guide wheel 406 of the push rod 405 The guide wheels 406 at the bottom of the ejector rods 405 are in conflict with one side of the bottom of the latch 402, and the guide wheels 406 at the bottom of the ejector rods 405 extend to the outside of the bottom of the fixed plate 301 and conflict with the top of the driving block 401. Through the installation of the two sets of driving blocks 401, the placement plate 302 follows the fixed plate 301 and the table panel 2 to slide to a certain position and wait for the model to be printed. The guide wheels 406 at the bottom of the two sets of ejector rods 405 will conflict with the two sets of driving blocks 401 and rise, and the guide wheels 406 at the top of the two sets of ejector rods 405 will rotate the two sets of The bottom side of the latch 402 is in conflict, so that the latch 402 can slide away from the elastic force of the return spring 404. After the latch 402 is inserted into the slot 403, the placement plate 302 is firmly installed inside the installation slot 305. When unloading after printing is completed, the placement plate 302 moves to one end of the printer 1, the guide wheel 406 is separated from the drive block 401, and the latch 402 is not subject to conflict and shrinks, making it easy to release the limit of the placement plate 302 for disassembly.
[0029] Specifically, such as Figure 2 、 Figure 12 and Figure 13As shown, a heat dissipation mechanism 7 is installed on the placement plate 302, and the heat dissipation mechanism 7 includes a mounting block 701. A mounting block 701 is installed on the top of one end of the placement plate 302, and the mounting block 701 is a trapezoidal structure. A through slot 704 is provided inside the mounting block 701. Multiple nozzles 702 with different elevation angles are installed on one side of the mounting block 701, and a connecting pipe 703 is installed at the bottom center of the mounting block 701. The connecting pipe 703 extends to the outside of the fixed plate 301. The installation of the mounting block 701 facilitates the connection of the nozzle 702, and the connection between the connecting pipe 703 and the external air pipe facilitates the delivery of external gas to the inside of the through slot 704, and is ejected through the nozzles 702 with multiple different elevation angles, so as to realize air blowing and heat dissipation of the printed model, which is convenient for rapid molding and demolding.
[0030] Specifically, such as Figure 1 、 Figure 13 and Figure 14 As shown, a control mechanism 8 is installed on the placement plate 302, and the control mechanism 8 includes a column 802. The center of the bottom of the mounting block 701 is vertically connected to the column 802. The bottom of the column 802 passes through the fixed plate 301 and extends to the outside of the bottom of the table panel 2. The top of the column 802 extends to the inside of the through groove 704. A conveying groove 807 is provided at the center of the top of the column 802. The connecting pipe 703 is vertically connected to the outside of the top of the column 802. The connecting pipe 703 extends to the inside of the bottom of the conveying groove 807. A sealing plug 806 is snap-connected to the top of the column 802. A control rod 803 is installed at the center line of the column 802. The control rod 803 is slidably connected to the inside of the column 802 by an extrusion spring 805. The top of the control rod 803 extends to the inside of the conveying groove 807 and is vertically connected to the bottom of the sealing plug 806. The control rod 8 03 is provided with a top ball 804 at the bottom, and a trapezoidal control board 801 is provided at the top of one end of the printer 1, and the top ball 804 conflicts with the control board 801. The installation of the column 802 facilitates the connection of the connecting pipe 703, and external gas can be transported to the inside of the conveying groove 807. When there is no external force to conflict with the control rod 803, the control rod 803 pulls the sealing plug 806 to block the conveying groove 807 through the interference of the extrusion spring 805, and the blowing operation cannot be performed. When the material is unloaded after printing is completed, the placement plate 302 follows the fixed plate 301 and the table panel 2 to slide to one end of the printer 1, and the top ball 804 at the bottom of the control rod 803 conflicts with the control board 801, so that the control rod 803 rises, and the sealing plug 806 is separated from the conveying groove 807, so that the gas can be discharged and dissipated.
[0031] When the present invention is in use, first, the fixing plate 301 is detachably connected to the table panel 2 on the printer 1 by bolts, and the table panel 2 and the fixing plate 301 are moved to the front end of the printer 1 by controlling the printer 1, and the placement plate 302 is lifted by holding the two handles 303, so that the placement plate 302 and the installation slot 305 can be inserted. The placement plate 302 will resist the support block 304, and the support block 304 will be freed from the elastic force of the resistance spring 306 and shrink, so that the placement plate 302 can slide to a certain position and engage with the inside of the installation slot 305. After the placement plate 302 is stably installed, the support block 304 can resist the placement plate 302 under the resistance of the resistance spring 306, and the placement plate 302 and the inside of the installation slot 305 are firmly engaged and will not loosen. After the installation of the two sets of drive blocks 401, the placement plate 302 follows the fixed plate 301 and the table panel 2 to slide to a certain position and wait for the model to be printed, the guide wheels 406 at the bottom of the two sets of ejector rods 405 will resist the two sets of drive blocks 401 and rise, and the guide wheels 406 at the top of the two sets of ejector rods 405 will resist the bottom side of the two sets of latches 402, so that the latches 402 can get rid of the elastic force of the return spring 404 and slide. After the latches 402 are inserted into the slots 403, the placement plate 302 and the installation slots 305 are firmly installed. When the printing is completed and the material is unloaded, the placement plate 302 moves to one end of the printer 1, the guide wheels 406 separate from the drive blocks 401, and the latches 402 are not resisted and retracted, which is convenient for releasing the limit of the placement plate 302 for disassembly. The opening of 04 is conducive to the installation of multiple slides 501. Through the support of multiple connecting springs 506, the tops of multiple slides 501 are flush with the top of the placement plate 302, which is convenient for placing the model stably during printing. Through the installation of multiple fixed shafts 502, it is conducive to supporting the bottoms of multiple slides 501 to prevent the slides 501 from sliding down. Through the installation of multiple top blocks 505, when the multiple slides 501 are pulled synchronously, the slides 501 will get rid of the elastic force of the connecting springs 506 and slide to a certain position, so that the tops of the multiple slides 501 are separated from the bottom of the model. Then, when the slides 501 continue to slide, the top block 505 at the bottom of the slide 501 conflicts with the fixed shaft 502, and the fixed shaft 502 conflicts with the top rod 405 to rise, so that the top block 505 drives the slide 501 to swing The elastic force of the disconnecting spring 506 slides upward, which is conducive to lifting the model, separating the bottom of the model from the placement plate 302, and realizing demoulding and removal of the model, which is convenient to operate. The installation of multiple rollers 503 facilitates the smoother lifting of the top block 505 after it conflicts with the roller 503, playing a one-way and friction-reducing role. The installation of the guide block 507 facilitates the positioning of the slide plate 501, so that the slide plate 501 cannot slide upward, thereby ensuring the stability of the slide plate 501. After the slide plate 501 slides to a certain position, the guide block 507 allows the slide plate 501 to slide obliquely upward. The installation of the drive shaft 601 facilitates the connection of multiple cams 602. The cooperation of the two reducers 603 and the drive motor 604 realizes the control of the rotation of the drive shaft 601.The driving shaft 601 drives multiple cams 602 to resist multiple slides 501, so that the multiple slides 501 can slide and push up to realize the separation of the model. The installation of the reducer 603 makes the driving shaft 601 rotate slowly and has a large torque, which is conducive to better driving the slide 501 to demould. The installation of the mounting block 701 is conducive to the connection of the nozzle 702. The connection between the connecting pipe 703 and the external air pipe is conducive to the external gas being transported to the inside of the through groove 704, and sprayed out through multiple nozzles 702 with different elevation angles, so as to realize the blowing and heat dissipation of the printed model, which is convenient for rapid molding and demoulding. The installation of the upright 802 facilitates the connection of the connecting tube 703, allowing external air to be delivered to the interior of the delivery trough 807. When there is no external force resisting the control rod 803, the control rod 803 pulls the sealing plug 806 through the resistance of the extrusion spring 805, blocking the delivery trough 807 and preventing air blowing. When the material is unloaded after printing is completed, the placement plate 302 follows the fixed plate 301 and the table plate 2 to slide to one end of the printer 1. The top ball 804 at the bottom of the control rod 803 contacts the control plate 801, causing the control rod 803 to rise, and the sealing plug 806 separates from the delivery trough 807, allowing the air to be discharged and dissipated.
