Description
Technical Field
[0001] The invention relates to the technical field of injection molding equipment, and more particularly to an injection molding equipment with a flash removal component. Background Art
[0002] Flash is a common defect in the injection molding process. Flash is an extra edge formed when the resin melt overflows from the mold parting surface due to incomplete mold closure or excessive injection pressure. The existence of flash not only affects the quality of the product, but also affects the life of the mold. Therefore, removing flash is an important task in the injection molding process.
[0003] Existing flash removal of products is mostly done by workers manually after injection molding is completed and ejected. The flash removal efficiency is low, and the products are affected by the workers' operation and have uneven quality.
[0004] In view of the above-mentioned related technologies, the inventor believes that the processing efficiency and quality of the product can be improved by performing a flash removal operation after the product is formed and before it is ejected. In view of this, we propose an injection molding device with a flash removal component. Summary of the invention
[0005] The purpose of the present invention is to provide an injection molding device with a flash removal component, which solves the technical problems of low efficiency and difficult quality control of manual flash removal of products in the prior art, and achieves the technical effect of improving flash processing efficiency and product quality.
[0006] The embodiment of the present invention provides an injection molding device with a flash removal component, comprising an injection molding machine body and a mold, wherein an injection mold group is installed on the injection molding machine body, and the injection mold group is inserted into a nozzle of the mold for injection molding and feeding;
[0007] A multi-axis manipulator is fixedly installed on the main body of the injection molding machine, a positioning box is fixedly installed on the output end of the multi-axis manipulator, and the multi-axis manipulator is used to adjust the spatial position of the positioning box;
[0008] The positioning box is provided with a plurality of through holes, and a plurality of positioning cylinders coaxial with the through holes are fixedly mounted on the positioning box, and the ejector pin of the mold pushes the product into the positioning cylinder for positioning;
[0009] A suction cup is fixedly mounted on the positioning cylinder for adsorbing and fixing the product;
[0010] The positioning box is rotatably connected to a plurality of first gears, a second motor is fixedly mounted on the positioning box, an output shaft of the second motor is fixedly connected to a second gear, and the second gear is meshed with the plurality of first gears for transmission;
[0011] An adjusting assembly is installed on the first gear, and a scraper for removing burrs is installed on the adjusting assembly.
[0012] By adopting the above technical scheme, after the mold is opened and the ejector has not ejected the product, the multi-axis manipulator drives the positioning box to move to fit with the surface of the mold core. At this time, the through hole coincides with the axis of the ejector, and the product is inserted into the through hole. The ejector rod of the injection molding machine body works to make the ejector push the product into the positioning cylinder for positioning, and the suction cup absorbs and fixes the product to realize the product transfer process. The scraper is driven to rotate by a plurality of first gears to remove the flash of the product. By removing the flash while the injection mold is opened, the cost of subsequent flash processing is effectively reduced and the quality of the product is improved.
[0013] As an optional solution of the technical solution of the document of the present invention, the number of the through holes is the same as the number of products formed by the mold core, and the inner diameter of the through hole is larger than the outer diameter of the product;
[0014] The outer wall of the product is in contact with the inner wall of the positioning tube.
[0015] As an optional solution of the technical solution of the document of the present invention, the depth of the positioning tube is smaller than the height of the product.
[0016] By adopting the above technical solution, the depth of the positioning cylinder is smaller than the height setting of the product, ensuring that when the product is in the positioning cylinder, the flash of the product's mating surface is outside the positioning cylinder, reducing the difficulty of the cutter to remove the flash.
[0017] As an optional solution of the technical solution of the document of the present invention, the first gear is colinear with the axis of the through hole.
[0018] As an optional solution of the technical solution of the document of the present invention, the adjustment component includes a support column and a first elastic member, the support column is slidably connected with an adjustment rod, the scraper is installed on the adjustment rod, the support column is fixedly mounted with a first electromagnet, the adjustment rod is fixedly mounted with a first armature, one end of the first elastic member is fixedly connected to the support column, and the other end is fixedly connected to the adjustment rod.
[0019] By adopting the above technical solution, after the first electromagnet is energized, the first armature is fixed on the first electromagnet, thereby fixing the adjusting rod on the support column. The setting of the first elastic member, under the action of elastic force, keeps the adjusting rod always on the side away from the through hole, thereby ensuring that the scraper is away from the through hole, avoiding scratching the product when positioning the product into the positioning cylinder, thereby affecting the product quality.
[0020] As an optional solution of the technical solution of the document of the present invention, a slide groove is provided on the adjusting rod, an extension rod is slidably connected in the slide groove, a second elastic member is installed in the slide groove, one end of the second elastic member is fixedly connected to the adjusting rod, and the other end is fixedly connected to the extension rod;
[0021] The scraper is fixedly mounted on the extension rod;
[0022] A second armature is fixedly mounted on the extension rod, and a second electromagnet is fixedly mounted on the bottom of the slide slot.
[0023] By adopting the above technical solution, after the second electromagnet is energized, the second armature is magnetically fixed on the second electromagnet, the extension rod stretches the second elastic member and pushes the scraper out of the adjustment rod, and the second elastic member is set, when the second electromagnet is powered off, the second elastic member drives the extension rod and the scraper to slide into the slide groove, so as to store the scraper, so as to avoid the scraper scratching the product surface when the product is blown out after the flash processing is completed, thereby reducing the risk of damaging the product;
[0024] When removing the flash of the product, the first electromagnet and the second electromagnet are energized, and the first armature and the second armature are fixed respectively by the magnetic attraction force. At this time, the scraper extends out of the adjustment rod and is at the edge of the product. The output shaft of the second motor drives the second gear to rotate, and drives the first gears to rotate through meshing transmission. The first gear drives the support column, the adjustment rod, the extension rod and the scraper to rotate around the axis of the first gear, so that the scraper removes the flash of the product, effectively improving the processing efficiency of the product flash and the quality of the product, and reducing the labor cost of the later product flash processing;
[0025] After the flash is processed, the multi-axis manipulator drives the positioning box to move to one side of the front template, the second electromagnet is powered off, the ejector pin is reset, the scraper is retracted into the slide, and the working mode of the suction cup is switched from suction to blowing. The product is blown out of the through hole and falls into the material receiving area, realizing the process of product separation. The multi-axis manipulator drives the positioning box to reset and leave the injection molding area to prepare for the next injection molding.
[0026] As an optional solution of the document technical solution of the present invention, the number of the scrapers includes at least two groups, and the two groups of scrapers are arranged in an eight-shaped inclined manner.
[0027] By adopting the above technical solution, two sets of scrapers are set, and the first gear can effectively remove the flash by rotating clockwise or counterclockwise. The scraper is set at an angle, which effectively improves the scraper's tolerance during the flash removal process and reduces the risk of chipping.
[0028] As an optional solution of the technical solution of the document of the present invention, a material receiving area is opened on the injection molding machine body, and a rotating plate is rotatably connected in the material receiving area. A first motor is fixedly installed in the injection molding machine body, and the output shaft of the first motor is fixedly connected to the rotating plate for adjusting the tilt direction of the rotating plate in the material receiving area.
[0029] By adopting the above technical solution, after the product is injection molded and before the positioning box is attached to the mold core, the output shaft of the first motor drives the rotating plate to rotate and tilt. If there are products that accidentally fall during this process, they can be collected collectively. In the process from the positioning box being attached to the mold core to the product being blown out, the output shaft of the first motor drives the rotating plate to rotate and tilt it to the other side, so that the products with the flash removed can be uniformly collected. The rotating plate rotatably arranged in the receiving area can effectively classify the products that have been processed and those that have not, to avoid mixing of products of different qualities, resulting in the problem of inconsistent product quality, thereby avoiding subsequent unnecessary sorting steps.
[0030] As an optional solution of the technical solution of the present invention, a plurality of telescopic cylinders are fixedly installed on the positioning box, and an adjustment frame is fixedly installed on the output shaft of the telescopic cylinder, and the adjustment frame is slidably connected to the positioning box through a guide rail;
[0031] The movement direction of the adjusting rod is perpendicular to the axis of the through hole.
[0032] By adopting the above technical scheme, when the first elastic member is in a free state, the adjusting rod is in a corresponding position directly above or directly below the adjusting frame, and the adjusting frame is used to push the adjusting rod to slide on the supporting column, thereby adjusting the position of the scraper; when it is necessary to adjust the scraping position of the product flash, the adjusting rod is reset to the initial position, at which time the adjusting rod is in the corresponding position of the adjusting frame, and the output shaft of the telescopic cylinder drives the adjusting frame to push the adjusting rod to slide on the supporting column to adjust the position of the scraper. After the adjustment is completed, the first electromagnet is energized to fix the first armature and the adjusting rod to ensure the relative stability of the scraper. The adjusting frame is reset under the drive of the telescopic cylinder to avoid collision problems caused by sliding failure of the adjusting rod, thereby improving the stability of operation. By adjusting the relative position of the scraper and the product flash, the depth of product flash removal can be controlled, thereby improving the operational flexibility of flash removal.
[0033] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:
[0034] 1. When the mold is opened after the injection molding is completed, the multi-axis manipulator drives the positioning box to move to fit with the surface of the mold core, inserts the product into the through hole, and the ejector pin of the mold pushes the product into the positioning cylinder for positioning and fixes the product by suction cups, thereby realizing rapid transfer and positioning of the product, and driving the scraper to rotate through a plurality of first gears to realize the removal of the flash of the product. By removing the flash while opening the mold for injection molding, the cost of subsequent flash processing is effectively reduced, and the processing efficiency and quality of product flash are improved.
[0035] 2. After the first electromagnet of the present invention is energized, the first armature is fixed on the first electromagnet, thereby fixing the adjusting rod on the supporting column. The arrangement of the first elastic member, under the action of elastic force, keeps the adjusting rod always on the side away from the through hole, thereby ensuring that the scraper is away from the through hole, avoiding scratching the product when positioning the product into the positioning cylinder, thereby affecting the product quality.
[0036] 3. After the second electromagnet of the present invention is energized, the second armature is magnetically fixed on the second electromagnet, the extension rod stretches the second elastic part and pushes the scraper out of the adjusting rod. The second elastic part is arranged so that when the second electromagnet is powered off, the second elastic part drives the extension rod and the scraper to slide into the slide groove, thereby storing the scraper, avoiding scratches on the product surface by the scraper when the product is put in or blown out, thereby reducing the risk of damaging the product.
[0037] 4. The present invention can effectively classify products that have been processed and those that have not been processed by rotatably arranging a rotating plate in the material receiving area, thereby avoiding the mixing of products of different qualities and causing the problem of uneven product quality, thereby avoiding subsequent unnecessary sorting steps.
[0038] 5. The present invention can adjust the position of the scraper by setting the adjustment frame, thereby controlling the flash removal depth of the product and improving the flexibility of the flash removal operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] 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.
[0051] Reference Figures 1 to 4The present invention discloses an injection molding device with a flash removal component, including an injection molding machine body 1, a material receiving area 11 is provided on the injection molding machine body 1, a rotating plate 12 is rotatably connected in the material receiving area 11, a first motor (not shown in the figure) is fixedly installed in the injection molding machine body 1, and the output shaft of the first motor is fixedly connected to the rotating plate 12, and the output shaft of the first motor drives the rotating plate 12 to rotate in the material receiving area 11. After the injection molding is completed, the conveying direction of the dropped product can be adjusted as needed to achieve product separation; an injection mold 2 is slidably connected to the injection molding machine body 1, and the injection mold 2 includes a hopper 21, a barrel 22 connected to the hopper 21, a screw 23 and a heater 24, etc., the injection plastic in the hopper 21 enters the barrel 22 and is heated and kept warm by the heater 24, the screw 23 rotates to convey the molten material and cooperates with the action of the driving group to push the molten material from the mouth of the barrel 22 into the nozzle 35 of the mold 3 for injection molding and feeding. It should be noted that the injection molding machine body 1 and the injection mold 2 are conventional injection molding machine equipment, and their structural components will not be described in detail here.
[0052] The mold 3 includes a rear template 31, a front template 32, a base 33, a top plate 34 and a nozzle plate 38. The rear template 31 is fixed on the base 33, and the base 33 is fixedly mounted on the demoulding drive assembly of the injection molding machine body 1. The demoulding drive assembly of the injection molding machine body 1 is used to drive the base 33 and the rear template 31 to move, so that the front template 32 is separated and demoulded from the rear template 31. A guide column is fixedly mounted on the top plate 34, and a guide sleeve is fixedly mounted on the rear template 31. The guide column and the guide sleeve are plugged and matched. The nozzle plate 38 and the front template 32 are both mounted on a plurality of guide columns, and the nozzle plate 38 is located between the top plate 34 and the front template 32. The top plate 34 is fixed on the injection port side of the injection molding machine body 1, and the nozzle 35 is fixedly mounted on the top plate 34. A mold core 36 is fixedly installed on the template 31. After the mold is closed, a molding cavity is formed between the mold core 36 and the front template 32, and the molten material enters the molding cavity from the nozzle 35 through the runner, thereby realizing injection molding. When the mold is opened, the demoulding drive component of the injection molding machine body 1 drives the base 33 and the rear template 31 to move backward, and the front template 32 moves backward accordingly, and the gate plate 38 slides to separate the product from the runner. After moving to the set stroke, the front template 32 is separated from the mold core 36 and the rear template 31 driven by the guide column, and the product remains on the mold core 36 under the influence of the injection shrinkage rate and the draft angle. The ejector rod of the injection molding machine body 1 pushes the ejector pin plate to move, thereby driving the ejector pin 37 to slide relative to the mold core 36, thereby realizing the separation of the product from the mold core 36. It should be noted that the above-mentioned injection mold structure and the mold opening and closing processes are conventional means of the injection mold design process, and its detailed structure will not be repeated. The above introduction is used to illustrate that after the injection molding of the product is completed, the product and the runner can be separated, so as to facilitate the subsequent product flash removal to proceed normally.
[0053] Reference Figures 5 to 10A multi-axis manipulator 4 is fixedly installed on the injection molding machine body 1, and the number of axes of the multi-axis manipulator 4 is at least three axes. A positioning box 5 is fixedly installed on the output end of the multi-axis manipulator 4, and the multi-axis manipulator 4 is used to adjust the spatial position of the positioning box 5. A plurality of through holes 51 are opened on the positioning box 5, and the number of through holes 51 is the same as the number of products that can be formed by the mold core 36. The inner diameter of the through hole 51 is larger than the outer diameter of the product. A plurality of positioning cylinders 52 are fixedly installed on the positioning box 5, and the positioning cylinders 52 correspond to the through holes 51 one by one, and the axis of the positioning cylinder 52 is colinear with the axis of the through hole 51. The positioning cylinder 52 is used for positioning the product. When the product is in the positioning cylinder 52, the outer wall of the product fits with the inner wall of the positioning cylinder 52, and the depth of the positioning cylinder 52 is less than the height of the product, so as to ensure that when the product is in the positioning cylinder 52, the flash of the mold surface of the product is on the outside of the positioning cylinder 52, and a suction hole is opened at the bottom of the positioning cylinder 52, and a suction cup 53 is fixedly installed in the suction hole, and the suction cup 53 is connected to the booster device.
[0054] After the mold is opened and the ejector pin 37 has not ejected the product, the multi-axis manipulator 4 drives the positioning box 5 to move to fit the surface of the mold core 36. At this time, the through hole 51 coincides with the axis of the ejector pin 37, and the product is inserted into the through hole 51. The ejector rod of the injection molding machine body 1 works to push the ejector pin 37 to insert the product into the positioning cylinder 52 for positioning, and the suction cup 53 absorbs and fixes the product, thereby realizing the product transfer process and facilitating the subsequent deburring operation.
[0055] A plurality of first gears 54 are rotatably connected to the positioning box 5, and the first gears 54 are colinear with the axis of the through hole 51. A second motor 55 is fixedly installed on the positioning box 5, and a second gear 56 is fixedly connected to the output shaft of the second motor 55, and the second gear 56 is meshed and driven with a plurality of first gears 54. It should be noted that the output shaft of the second motor 55 drives the second gear 56 to rotate in a reciprocating manner. If the second gear 56 rotates clockwise for the first time, the second motor 55 drives the second gear 56 to rotate counterclockwise in the next rotation, thereby realizing the reciprocating rotation of the first gear 54, thereby avoiding the risk of winding.
[0056] A support column 6 is fixedly mounted on the first gear 54, and an adjustment rod 61 is slidably connected to the support column 6. The movement direction of the adjustment rod 61 is perpendicular to the axis of the through hole 51. A first electromagnet 62 is fixedly mounted on the support column 6, and a first armature 63 is fixedly mounted on the adjustment rod 61. After the first electromagnet 62 is energized, the first armature 63 is fixed on the first electromagnet 62, thereby fixing the adjustment rod 61 on the support column 6. A first elastic member 64 is arranged on the support column 6, and one end of the first elastic member 64 is fixedly connected to the support column 6, and the other end is fixedly connected to the adjustment rod 61. The arrangement of the first elastic member 64, under the action of elastic force, keeps the adjustment rod 61 always on the side away from the through hole 51, thereby ensuring that the scraper 68 is away from the through hole 51, avoiding scratching the product when the product is positioned and placed in the positioning cylinder 52, thereby affecting the product quality.
[0057] A slide groove 65 is provided on the adjusting rod 61, and an extension rod 66 is slidably connected in the slide groove 65. A second elastic member 67 is installed in the slide groove 65. One end of the second elastic member 67 is fixedly connected to the adjusting rod 61, and the other end is fixedly connected to the extension rod 66. Two groups of scrapers 68 are fixedly installed at the bottom of the extension rod 66. The two groups of scrapers 68 are inclined in an eight-shaped shape and are used to scrape off the flash. A second armature 69 is fixedly installed on the extension rod 66, and a second electromagnet 691 is fixedly installed at the bottom of the slide groove 65. After the second electromagnet 691 is energized, the second armature 69 is magnetically fixed on the second electromagnet 691, and the extension rod 66 stretches the second elastic member 67 and pushes the scraper 68 out of the adjusting rod 61. The second elastic member 67 is arranged so that when the second electromagnet 691 is de-energized, the second elastic member 67 drives the extension rod 66 and the scraper 68 to slide into the slide groove 65, thereby storing the scraper 68, thereby preventing the scraper 68 from scratching the product surface when the product is blown out after the flash processing is completed, thereby reducing the risk of damaging the product.
[0058] When removing the flash of the product, the first electromagnet 62 and the second electromagnet 691 are energized, and the first armature 63 and the second armature 69 are fixed respectively by the magnetic attraction force. At this time, the scraper 68 extends out of the adjusting rod 61 and is at the edge of the product (at the parting surface). The output shaft of the second motor 55 drives the second gear 56 to rotate and drives the first gears 54 to rotate through the meshing transmission. The first gear 54 drives the support column 6, the adjusting rod 61, the extension rod 66 and the scraper 68 to rotate around the axis of the first gear 54, so that the scraper 68 can remove the flash of the product, effectively improving the processing efficiency of the product flash and the quality of the product, and reducing the labor cost of the flash processing of the later products.
[0059] After the flash is processed, the multi-axis manipulator 4 drives the positioning box 5 to move to one side of the front template 32, the second electromagnet 691 is powered off, the ejector pin 37 is reset, the scraper 68 is retracted into the slide groove 65, and the working mode of the suction cup 53 is switched from suction to blowing. The product is blown out from the through hole 51 and falls into the material receiving area 11, realizing the process of product separation. The multi-axis manipulator 4 drives the positioning box 5 to reset and leave the injection molding area to prepare for the next injection molding.
[0060] It should be noted that, after the product is injection molded and before the positioning box 5 is attached to the mold core 36, the output shaft of the first motor drives the rotating plate 12 to rotate and tilt. If there are products that accidentally fall during this process, they can be collected in a centralized manner. In the process from when the positioning box 5 is attached to the mold core 36 to when the product is blown out, the output shaft of the first motor drives the rotating plate 12 to rotate and tilt it to the other side, so that the products with the flash removed can be uniformly collected. The rotating plate 12 that is rotatably arranged in the receiving area 11 can effectively classify the products that have been processed or not, avoid mixing products of different qualities, and cause the problem of different product quality, thereby avoiding unnecessary subsequent sorting steps.
[0061] A plurality of telescopic cylinders 7 are fixedly mounted on the positioning box 5, and an adjusting frame 8 is fixedly mounted on the output shaft of the telescopic cylinder 7. The adjusting frame 8 is slidably connected to the positioning box 5 via a guide rail. When the first elastic member 64 is in a free state, the adjusting rod 61 is at a corresponding position directly above or directly below the adjusting frame 8 (i.e., the initial position of the adjusting rod 61 relative to the through hole 51). The adjusting frame 8 is used to push the adjusting rod 61 to slide on the supporting column 6, thereby adjusting the position of the scraper 68. When it is necessary to adjust the scraping position of the product flash (increase or decrease the cutting depth of the flash), the adjusting rod 61 is reset to the initial position. At this time, the adjusting rod 61 is in the corresponding position of the adjusting frame 8. The output shaft of the telescopic cylinder 7 drives the adjusting frame 8 to push the adjusting rod 61 to slide on the support column 6 to adjust the position of the scraper 68. After the adjustment is completed, the first electromagnet 62 is energized to fix the first armature 63 and the adjusting rod 61 to ensure the relative stability of the scraper 68. The adjusting frame 8 is reset under the drive of the telescopic cylinder 7 to avoid the sliding failure of the adjusting rod 61 and the collision problem, thereby improving the operation stability. By adjusting the relative position of the scraper 68 and the product flash, the flash removal depth of the product can be controlled, thereby improving the operational flexibility of flash removal.
[0062] When the injection molding device with a flash removal component disclosed in the embodiment of the present invention is used, according to the preset flash removal depth, the output shaft of the telescopic cylinder 7 drives the adjustment frame 8 to push the adjustment rod 61 to slide on the support column 6 to adjust the position of the scraper 68. After the adjustment is completed, the first electromagnet 62 is energized to fix the first armature 63 and the adjustment rod 61, and the adjustment frame 8 is reset under the drive of the telescopic cylinder 7;
[0063] After the mold 3 is closed, the injection module 2 injects the molten material into the molding cavity through the nozzle 35 of the mold 3. After the molten material is cooled and formed, the demoulding drive assembly of the injection molding machine body 1 drives the base 33 and the rear mold plate 31 to move backward, and the front mold plate 32 and the rear mold plate 31 are separated. The product is left on the mold core 36 under the influence of the injection shrinkage rate and the draft angle.
[0064] The multi-axis manipulator 4 drives the positioning box 5 to move to fit the surface of the mold core 36. At this time, the through hole 51 and the axis of the ejector 37 are in line, and the product is inserted into the through hole 51. The ejector rod of the injection molding machine body 1 works, so that the ejector 37 pushes the product into the positioning cylinder 52 for positioning, and the suction cup 53 absorbs the product and fixes the product in the positioning cylinder 52.
[0065] After the second electromagnet 691 is energized, the second armature 69 is magnetically fixed on the second electromagnet 691, and the extension rod 66 pushes the scraper 68 out of the adjustment rod 61. The output shaft of the second motor 55 drives the second gear 56 to rotate, and drives the first gears 54 to rotate through meshing transmission. The first gear 54 drives the support column 6, the adjustment rod 61, the extension rod 66 and the scraper 68 to rotate around the axis of the first gear 54, so that the scraper 68 can remove the flash of the product.
[0066] After the flash is removed, the multi-axis manipulator 4 drives the positioning box 5 to move to one side of the front template 32, the second electromagnet 691 is powered off and the ejector pin 37 is reset, the scraper 68 is retracted into the slide groove 65, and the working mode of the suction cup 53 is switched from suction to blowing. The product is blown out from the through hole 51 and falls into the material receiving area 11, realizing the process of product separation. The multi-axis manipulator 4 drives the positioning box 5 to reset and leave the injection molding area to prepare for the next injection molding.
