Description

Technical Field

[0001] The invention relates to the technical field of automobile parts manufacturing, and in particular to an automobile turn signal lampshade injection molding machine and a process thereof. Background Art

[0002] Injection mold is a molding method that combines injection and molding. At a certain temperature, completely molten plastic material is injected into the mold cavity. After cooling and solidification, it can be formed. Injection molds are needed when making car turn signal lampshades.

[0003] The inventors found in their daily work that the temperature of completely melted plastic is extremely high. During the injection molding process, when the mold is closed, some excess melted plastic will fall from the mold into the injection molding machine under the action of mold extrusion, causing most of the interior of the machine body to be covered with melted plastic. The melted plastic will cause serious pollution to the interior of the machine body after molding, making it difficult to clean and reducing the aesthetics. Moreover, after extrusion, the mold will drop some scraps of the molded plastic. When too much accumulates, manual cleaning is required, which reduces working performance and practicality.

DETAILED DESCRIPTION

[0047] The following is combined with Figure 1-13 The present invention is further described with examples:

[0048] An automobile turn signal lampshade injection molding machine comprises an injection molding machine 1, wherein an injection mold device 11 is arranged in the middle of the top of the injection molding machine 1; an accommodating chamber 12 is provided inside the injection molding machine 11, a waste outlet 13 is provided on one side wall of the accommodating chamber 12, and a collecting box 14 is arranged at the end of the waste outlet 13; guide blocks 2 are fixedly connected to both sides of the upper part of the accommodating chamber 12; a conveying mechanism 3 and a crushing mechanism 5 are arranged on the rear side of the injection molding machine 1; and a protective mechanism 4 is arranged on one side of the accommodating chamber 12.

[0049] In this embodiment, a guide surface 21 is formed on one side of the guide block 2. A portion of the melted plastic and the shaped scraps will fall onto the upper surface of the conveyor belt 33, and another portion of the melted plastic will fall onto the guide surface 21 on the guide block 2. The melted plastic and the shaped scraps are slid downward onto the upper surface of the conveyor belt 33 by the guide surface 21, so that the melted plastic and the shaped scraps can be effectively guided together to the conveyor belt 33.

[0050] In this embodiment, the conveying mechanism 3 includes a motor 31 fixedly supported on the upper end of one side of the support plate, the output end of the motor 31 is connected to a first rotating shaft 32, one end of the first rotating shaft 32 passes through the first rotating hole on the two side walls of the injection molding machine 1, and a first roller 321 is sleeved in the middle of the first rotating shaft 32, and a conveyor belt 33 is conveyed on the outer side of the first roller 321, and the inner ring of the conveyor belt 33 is covered with a second roller 34, a third roller 35, a fourth roller 36, a fifth roller 37, and a sixth roller 38, and a second rotating shaft 341 is sleeved inside the second roller 34, and both ends of the second rotating shaft 341 pass through the two side walls of the injection molding machine 1. In the second rotating hole, the third roller 35 is internally sleeved with a third rotating shaft 351, and both ends of the third rotating shaft 351 pass through the third rotating hole on the two side walls of the injection molding machine 1; the fourth roller 36 is internally sleeved with a fourth rotating shaft 361, and both ends of the fourth rotating shaft 361 pass through the fourth rotating holes on the two side walls of the injection molding machine 1; the fifth roller 37 is internally sleeved with a fifth rotating shaft 371, and both ends of the fifth rotating shaft 371 pass through the fifth rotating holes on the two side walls of the injection molding machine 1; the sixth roller 38 is internally sleeved with a sixth rotating shaft 381, and both ends of the sixth rotating shaft 381 pass through the sixth rotating holes on the two side walls of the injection molding machine 1. The starting motor 31 drives the first rotating shaft 32 to rotate clockwise, and the first rotating shaft 32 drives the first roller 321 to rotate clockwise. At the same time, the first rotating shaft 32 drives the first pulley 322 to rotate clockwise, and the power of the first pulley 322 drives the second pulley 323 to rotate clockwise through the first transmission belt 3221, and the second pulley 323 drives the third pulley 362 to rotate clockwise through the second transmission belt 3231, so that the fourth rotating shaft 361 and the second rotating shaft 341 rotate clockwise, and the fourth rotating shaft 361 and the second rotating shaft 341 drive the second roller 34 and the fourth roller 36 to rotate clockwise, and the first roller 321 rotates clockwise at the same time, and drives the conveyor The belt 33 conveys clockwise. After starting, a part of the melted plastic and the shaped scraps will fall on the upper surface of the conveyor belt 33, and the other part of the melted plastic will fall on the guide surface 21 on the guide block 2. The guide surface 21 is used to slide the melted plastic and the shaped scraps down onto the upper surface of the conveyor belt 33. As the conveyor belt 33 conveys clockwise, the melted plastic and the shaped scraps are conveyed to the crushing position. In order to prevent a large amount of melted plastic from appearing inside the machine body, the conveyor belt 33 can be used to convey the melted plastic and the shaped scraps that have just fallen out to the outside. It can be automatically circulated and conveyed without human intervention, avoiding the phenomenon of excessive accumulation of shaped scraps, and no manual cleaning is required, thereby improving work performance and providing practicality.

[0051] In this embodiment, the first rotating shaft 32 is sleeved with a first pulley 322 at one end of the outer side of the injection molding machine 1, and the first pulley 322 is connected to the second pulley 323 through the first transmission belt 3221. The second pulley 323 is sleeved on the outer side of one end of the second rotating shaft 341, and the second pulley 323 is connected to the third pulley 362 through the second transmission belt 3231. The third pulley 362 is sleeved on the outer side of one end of the fourth rotating shaft 361. The power of the first pulley 322 makes the conveyor belt 33 convey in a clockwise direction, which effectively avoids serious pollution, reduces the degree of pollution, makes cleaning more convenient, and improves the aesthetics.

[0052] In this embodiment, the protective mechanism 4 includes a fixed column 411 fixedly supported on both sides of the protective shell 41, a through hole 412 is opened at the lower end of one side wall of the protective shell 41, and the first through hole 413, the second through hole 414, and the third through hole 415 are opened on both side walls of the protective shell 41, and a scraper 42 is fixedly connected to one side of the lower part of the protective shell 41, and a first scraping surface 421 is formed on the upper end surface of the scraper 42, and a baffle 422 is formed on a side of the lower part of the scraper 42, and a discharge plate 43 is fixedly connected to the bottom of the waste discharge port 13, and a second scraping surface 431 is formed on one side end surface of the discharge plate 43, and an inclined surface 432 is formed on the upper surface of the discharge plate 43, and an arc plate 44 is arranged inside the protective shell 41, and a first overlap groove 45 and a second overlap groove 451 are opened on one side of the lower part of the protective shell 41, and both ends of the third rotating shaft 351 pass through the third through hole 415 on the protective shell 41. In order to prevent the broken plastic from randomly splashing inside the accommodating chamber 12, the protective shell 41 and the curved plate 44 are provided so that the broken plastic will not randomly splash inside the accommodating chamber 12, but can only randomly splash outward in the guide space formed by the protective shell 41 and the curved plate 44. After splashing, the splashed plastic is guided to the conveyor belt 33 through the inner side of the curved plate 44, ensuring that the broken plastic will fall on the conveyor belt 33, thereby improving practicality. By providing the baffle 422, the third roller 35 and the conveyor belt 33 can continue to maintain normal operation, effectively avoiding the problem of broken plastic being stuck between the conveyor belt 33 and the third roller 35, preventing the conveyor belt 33 from being damaged, and improving the service life.

[0053] After being guided by the second swing plate 67 and the first swing plate 61, the plastic falls onto the inclined surface 432 on the discharge plate 43. The scraped plastic and the broken plastic are guided to the inside of the collection box 14 through the inclined surface 432. The second scraping surface 431 on the discharge plate 43 scrapes the shaped plastic attached to the upper surface of the conveyor belt 33 for the second time, so as to completely remove the shaped plastic.

[0054] As the conveyor belt 33 continues to rotate clockwise, the shaped plastic on the upper surface of the conveyor belt 33 will be scraped off by the first scraping surface 421 on the scraper 42, and the scraped shaped plastic will be guided to the upper surface of the conveyor belt 33 by the inclined surface of the scraper 42. Through the setting of the scraper 42, the shaped plastic on the conveyor belt 33 can be automatically cleaned without human intervention, and the scraped shaped plastic can be guided to the upper surface of the conveyor belt 33, so as to avoid the scraped shaped plastic falling between the conveyor belt 33 and the rotation of the third roller 35, thereby reducing the degree of damage and thus improving practicality.

[0055] In this embodiment, the first scraping surface 421 contacts the outer side of the conveyor belt 33, the second scraping surface 431 contacts the outer side of the conveyor belt 33, and one side of the inclined surface 432 extends inside the collection box 14. It is beneficial that the inclined surface 432 can allow the guided rear plastic and the length of the inclined surface 432 to directly reach the inside of the collection box 14, thereby preventing the plastic from falling around the collection box 14.

[0056] In this embodiment, the crushing mechanism 5 includes a fourth transmission belt 51 that is transmission-connected to the second pulley 323, a fourth pulley 52 is sleeved on one side of the fourth transmission belt 51, a seventh rotating shaft 53 is sleeved inside the fourth pulley 52, a first rotating cylinder 531 is sleeved on the outer side of one end of the seventh rotating shaft 53, a plurality of first crushing pieces 532 are arranged at equal intervals along the axial direction of the first rotating cylinder 531, the first crushing pieces 532 are annularly connected to the outer side of the first rotating cylinder 531 at equal angles along the outer side of the first rotating cylinder 531, and both ends of the seventh rotating shaft 53 pass through the first through hole 413, wherein both ends of the seventh rotating shaft 551 pass through the seventh rotating hole on the two side walls of the injection molding machine 1 , one end of the seventh rotating shaft 53 is sleeved with a first gear 54, the first gear 54 is meshed with a second gear 55, and an eighth rotating shaft 551 is sleeved inside the second gear 55, both ends of the eighth rotating shaft 551 pass through the second through hole 414, and both ends of the eighth rotating shaft 551 pass through the second through hole 414, wherein both ends of the eighth rotating shaft 551 pass through the eighth rotating hole on the two side walls of the injection molding machine 1, and the outer side of one end of the eighth rotating shaft 551 is connected to a second rotating cylinder 56, and the second rotating cylinder 56 is provided with a plurality of second breaking pieces 57 at equal intervals along its axial direction, and the second breaking pieces 57 are annularly connected to the second rotating cylinder 56 at equal angles along the outer side of the second rotating cylinder 56. The clockwise rotation power of the second pulley 323 allows the fourth transmission belt 51 to drive the fourth pulley 52 to rotate clockwise, and the fourth pulley 52 drives the seventh rotating shaft 53 to rotate clockwise, and the seventh rotating shaft 53 drives the first gear 54 clockwise to engage with the second gear 55, so that the eighth rotating shaft 55 rotates counterclockwise, and the first rotating cylinder 531 and the second rotating cylinder 56 are rotated at the same time, wherein the first crushing piece 532 and the second crushing piece 57 rotate in opposite directions, and then the transported shaped scraps are broken. Through the setting of the first crushing piece 532 and the second crushing piece 57, larger shaped scraps are broken, and the volume of the shaped scraps after breaking becomes smaller, which will not occupy the internal space of the collection box 14, and more broken shaped scraps can be collected, thereby improving practicality.

[0057] In this embodiment, the first breaking piece 532 and the second breaking piece 57 are in a crossed state, and the inner surface of the arc plate 44 is covered on the periphery of the first breaking piece 532 and the second breaking piece 57. It is beneficial to better break the shaped scraps through the cross movement of the first breaking piece 532 and the second breaking piece 57.

[0058] In this embodiment, the guide mechanism 6 includes a first swing plate 61 fixedly supported inside the first overlap groove 45 and rotatably connected to the first fixed rod. The first swing plate 61 is hinged to the transmission rod 62 through the outside of the second fixed rod. One end of the transmission rod 62 is fixedly connected to a limit plate 621. A spring body 622 is connected between one side of the limit plate 621 and the inner wall of the injection molding machine 1. One end of the transmission rod 62 is penetrated by a sliding hole 623. The sliding hole 623 is opened on one side wall of the injection molding machine 1, wherein the top end of the transmission rod 62 is formed in a semi-spherical shape. The outer side surface of the semi-spherical shape abuts against a transmission plate 63, and the inner center of the transmission plate 63 is fixedly connected to the outer side of the fourth rotating shaft 361. One side of the first swing plate 61 is rotatably connected to the first folding plate 64 through the third fixed rod, and one side of the first folding plate 64 is rotatably connected to the connecting plate 65 through the fourth fixed rod. One side of the connecting plate 65 is connected to the second folding plate 66 through the fifth fixed rod. One side of the second folding plate 66 is rotatably connected to the second swing plate 67 through the sixth fixed rod. The second swing plate 67 is connected to the inner bottom of one side of the second overlap groove 451 through the seventh fixed rod. The scraped plastic and the broken plastic are being transported continuously by the conveyor belt 33, and have already started simultaneously with the conveyor belt 33 and the first crushing piece 532, so that the transmission plate 63 is driven by the fourth rotating shaft 361 to rotate the transmission plate 63 clockwise. The transmission plate 63 is provided with protruding blocks at low points and high points. When the transmission plate 63 rotates clockwise, the low point of the protruding block first contacts the semi-spherical shape at one end of the transmission rod 62. When the transmission plate 63 continues to rotate, the semi-spherical shape at one end of the transmission rod 62 gradually slides toward the high point of the protruding block. The transmission rod 62 is pressed to one side in the sliding hole 623, and is stretched to the spring body 622 by the fixed limit plate 621, so that it can move stably to one side. At the same time, one end of the transmission rod 62 drives the first swing plate 61 to rotate on the first fixed rod to expand inwardly by the second fixed rod. When the first swing plate expands outward, it drives the first folding plate 64 and the connecting plate 64 in sequence. The first folding plate 64 and the second folding plate 66 are combined in opposite directions, and the connecting plate 65 moves toward the discharge end, so that the second swing plate 67 rotates on the seventh fixed rod to expand inwardly, which is opposite to the rotation direction of the first swing plate 61, wherein one side of the second swing plate 67 and one side of the first swing plate 61 are in contact with the upper surface of the conveyor belt in an eight-shaped shape. The one side of the second swing plate 67 and the first swing plate 61 can be used to effectively guide the plastic on the pavement to the middle of the conveyor belt, which can effectively solve the problem that the discharged plastic cannot be caught at the edge of the inclined surface 432 and falls outward, and the inclined surface 432 can completely guide the discharged plastic to the inside of the collection box 14, thereby improving the working performance, eliminating the need for manual cleaning of the fallen plastic, and improving the working environment.

[0059] At the same time, in the guidance of one side of the second swing plate 67 and the first swing plate 61, due to the excessive rotation angle of the second swing plate 67 and the first swing plate 61, the plastic guide on one side of the rotation part cannot be out, and the plastic is excessively transported by the conveyor belt 33, so that the plastic is piled up at the rotation part. In order to avoid this phenomenon, the transmission plate 63 is set. After the highest point of the sliding protrusion of one end of the transmission rod 62 is reached, the transmission rod 62 gradually slides toward the lower point of the protrusion, and the spring body 622 gradually retracts toward the original state, so that one end of the transmission rod 62 is tightly against the protrusion. On the sliding surface of the protruding block, the first swing plate 61, the first folding plate 64, the connecting plate 65, the second folding plate 66, and the second swing plate 67 gradually return to their original positions. Through the setting of the protruding block, the second swing plate 67 and the first swing plate 61 are allowed to rotate at a small angle, so that the accumulated plastic is guided along one side of the second swing plate 67 and one side of the first swing plate 61 toward the middle of the conveyor belt 33. Then, through the transmission disk 63, one side of the second swing plate 67 and the first swing plate 61 are allowed to swing back and forth, and the plastic accumulation phenomenon is automatically cleaned up.

[0061] S1. Injection molding: Injecting completely molten plastic material into the mold cavity at a certain temperature;

[0062] S2, conveying: The melted plastic and the shaped scraps are conveyed to the crushing mechanism 5 by the conveyor belt 33 on the conveying mechanism 3, and the conveying can be automatically circulated without manual intervention, so as to avoid the phenomenon of excessive accumulation of shaped scraps;

[0063] S3, breaking: using the first breaking piece 532 and the second breaking piece 57 on the breaking mechanism 5 to break the shaped scraps, the volume of the shaped scraps after breaking becomes smaller, and will not occupy the internal space of the collection box 14, so more broken shaped scraps can be collected;

[0064] S4, first scraping: the shaped plastic on the surface of the conveyor belt 33 is scraped by the first scraping surface 421 on the scraper 42, so that the shaped plastic on the conveyor belt 33 is automatically cleaned without manual intervention;

[0065] S5, second scraping: the conveyor belt 33 performs a second scraping operation through the second scraping surface 431 on the discharge plate 43, which can completely remove the shaped plastic;

[0066] S6, guiding: through the guidance of the second swing plate 67 and the first swing plate 61, the plastic spread on the conveyor belt 33 is guided to the middle of the conveyor belt 33, thereby solving the problem that the edge of the inclined surface 432 cannot catch the discharged plastic and falls outward;

[0067] S7. Discharge: The plastic guided by the second swing plate 67 and the first swing plate 61 is discharged outward through the conveyor belt 33 and falls onto the discharge plate 43. The inclined surface 432 is used to guide the discharged plastic into the inside of the collection box 14 to avoid falling around the collection box 14.

[0068] The specific working principle of the present invention includes the following process:

[0069] First, during the injection molding process, when the mold is closed, some excess melted plastic will fall from the mold under the action of mold extrusion into the inside of the injection molding machine and some scraps of shaped plastic. At this time, the motor 31 can be started to drive the first rotating shaft 32 to rotate clockwise, and the first rotating shaft 32 drives the first roller 321 to rotate clockwise. At the same time, the first rotating shaft 32 drives the first pulley 322 to rotate clockwise, and the power of the first pulley 322 drives the second pulley 323 to rotate clockwise through the first transmission belt 3221, and the second pulley 323 drives the third pulley 362 to rotate clockwise through the second transmission belt 3231, so that the fourth rotating shaft 361 and the second rotating shaft 341 rotate clockwise, and the fourth rotating shaft 361 and the second rotating shaft 341 drive the second roller 34 and the fourth roller 36 to rotate clockwise, and rotate clockwise at the same time as the first roller 321, and drive the conveyor belt 33 to transport clockwise.

[0070] After starting, a part of the melted plastic and the shaped scraps will fall on the upper surface of the conveyor belt 33, and the other part of the melted plastic will fall on the guide surface 21 of the guide block 2. The melted plastic and the shaped scraps will slide down onto the upper surface of the conveyor belt 33 by means of the guide surface 21, and will be transported to the crushing position along with the clockwise conveyance of the conveyor belt 33 until the melted plastic and the shaped scraps are transported to the second roller 34. The shaped scraps are first transported to the first crushing piece 532 and the second crushing piece 57. The first crushing piece 53 2 and the second crushing piece 57 have already used the clockwise rotation power of the second pulley 323 to make the fourth transmission belt 51 drive the fourth pulley 52 to rotate clockwise, the fourth pulley 52 drives the seventh rotating shaft 53 to rotate clockwise, the seventh rotating shaft 53 drives the first gear 54 to mesh with the second gear 55 clockwise, and the eighth rotating shaft 55 rotates counterclockwise, so that the first rotating cylinder 531 and the second rotating cylinder 56 rotate at the same time, wherein the first crushing piece 532 and the second crushing piece 57 rotate in repelling directions, and then the transported shaped scraps are crushed.

[0071] After being broken, it falls downward onto the conveyor belt. As the conveyor belt 33 continues to rotate clockwise, the shaped plastic on the upper surface of the conveyor belt 33 will be scraped off by the first scraping surface 421 on the scraper 42 (the melted plastic has been retained for a long time, so that the melted plastic is shaped on the conveyor belt 33). The scraped shaped plastic is guided to the upper surface of the conveyor belt 33 by the inclined surface of the scraper 42.

[0072] The scraped plastic and the broken plastic are being conveyed by the conveyor belt 33, and have already started together with the conveyor belt 33 and the first breaking member 532, so that the transmission plate 63 is driven by the fourth rotating shaft 361 to rotate clockwise. The transmission plate 63 is provided with protruding blocks with low points and high points. When the transmission plate 63 rotates clockwise, the low point of the protruding block first contacts the semi-spherical shape at one end of the transmission rod 62. When the transmission plate 63 continues to rotate, the semi-spherical shape at one end of the transmission rod 62 gradually moves to the center of the transmission rod 62. The high point of the protruding block slides, and the transmission rod 62 slides to one side in the sliding hole 623 through the pressure of the protruding block, and is stretched on the spring body 622 through the fixed limit plate 621, so that it can move stably to one side. At the same time, one end of the transmission rod 62 drives the first swing plate 61 to rotate and expand inwardly by the first fixed rod using the second fixed rod. When the first swing plate expands outward, it drives the first folding plate 64, the connecting plate 65, the second folding plate 66, and the second swing plate 67 in sequence. The first folding plate 64, the connecting plate 65, the second folding plate 66, and the second swing plate 67 are 65. After the second folding plate 66 is powered, the first folding plate 64 and the second folding plate 66 are combined in opposite directions, and the connecting plate 65 moves toward the discharge end, thereby causing the second swing plate 67 to rotate on the seventh fixed rod to expand inwardly in a direction opposite to the rotation direction of the first swing plate 61, wherein one side of the second swing plate 67 and one side of the first swing plate 61 are in contact with the upper surface of the conveyor belt in an eight-shaped shape, and the one side of the second swing plate 67 and the first swing plate 61 can effectively guide the paved plastic to the middle of the conveyor belt. At the same time, through the setting of the transmission disk 63, after the one end of the transmission rod 62 slides to the highest point of the protruding block, the transmission rod 62 gradually slides against the lower point of the protruding block, and the spring body 622 gradually retracts toward the original state, so that one end of the transmission rod 62 is tightly in contact with the sliding surface of the protruding block, wherein the first swing plate 61, the first folding plate 64, the connecting plate 65, the second folding plate 66, and the second swing plate 67 gradually return to their original positions, thereby realizing automatic cleaning of plastic accumulation.

[0073] After being guided by the second swing plate 67 and the first swing plate 61, the plastic falls onto the inclined surface 432 on the discharge plate 43. The scraped plastic and the broken plastic are guided to the inside of the collection box 14 through the inclined surface 432. The second scraping surface 431 on the discharge plate 43 scrapes the shaped plastic attached to the upper surface of the conveyor belt 33 for the second time, so as to completely remove the shaped plastic.

[0074] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
