Description

Technical Field

[0001] The invention relates to the technical field of injection molded parts production, and in particular to production equipment for automobile injection molded parts. Background Art

[0002] Injection molding, also known as injection molding, is a process that uses plastic molding molds to make thermoplastic or thermosetting plastics into plastic products of various shapes. Injection molding can also be divided into injection molding and die casting, and the product raw materials can be divided into rubber injection molding and plastic injection molding.

[0003] A Chinese patent with application number CN202410451559.X discloses an intermittent feeding and conveying device for injection molding equipment, including a bottom plate, a pushing mechanism, an intermittent feeding mechanism and a loading mechanism. The pushing mechanism includes a heating cylinder and a reduction motor. An injection head is installed at one end of the heating cylinder, and a blanking port is provided at the top of the end of the heating cylinder away from the injection head. A sliding seat is fixedly installed at the bottom of the reduction motor, and the reduction motor is set on the bottom plate by sliding. The intermittent feeding mechanism includes a material storage cavity, and a feeding pipe is fixedly connected to the bottom of the material storage cavity.

DETAILED DESCRIPTION

[0021] In order to make the purpose, 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. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments.

[0022] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention. When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0023] like Figures 1 to 12 As shown, the present invention is a production equipment for automobile injection molded parts, comprising: an injection molding machine 1, a material storage box 2 connected to the feeding end of the injection molding machine 1, a pretreatment mechanism 3 for pretreatment of the injection molding raw materials in the material storage box 2 before injection molding, and a heat dissipation mechanism 4 for dissipating heat during the injection molding process of the injection molding machine 1.

[0024] The material storage box 2 is used to store injection molding raw materials. During injection molding, the injection molding raw materials in the material storage box 2 enter the injection molding machine 1 through the feeding end of the injection molding machine 1, and the injection molding machine 1 injection-moldes the injection molding raw materials.

[0025] Since the particles of the injection molding raw materials are of different sizes, when the particles of the injection molding raw materials are larger, the larger particles require longer time to melt and mix evenly, which can easily lead to uneven melt temperature distribution, affecting the uniformity and quality of the injection molded parts. In addition, if the particles are too large, it can easily lead to insufficient melt mixing, resulting in uneven color and inconsistent performance inside the injection molded parts. Therefore, in the present invention, a pretreatment mechanism 3 is set to pretreatment the injection molding raw materials to improve the quality of the injection molded parts.

[0026] In addition, the injection molding machine 1 generates a large amount of heat during operation, especially in the plasticizing stage. If the heat cannot be dissipated in time, the various components of the injection molding machine 1 may be damaged due to overheating, or even cause machine failure. In the present invention, the heat dissipation mechanism 4 is provided to effectively take away the heat, ensuring that the injection molding machine 1 operates within a suitable temperature range, thereby extending the service life of the machine, and when the injection mold is opened, the exhaust gas in the injection mold can be sucked away to avoid pollution to the environment.

[0027] The pretreatment mechanism 3 includes: a sieve plate 31 arranged in the storage box 2, a power component 32 for driving the sieve plate 31 to vibrate and screen, a feeding component 33 for conveying the injection molding raw materials to the sieve plate 31 for screening, a crushing component 34 for crushing the large particles of injection molding raw materials screened by the sieve plate 31, and an anti-blocking component 35 for jet cleaning the sieve holes of the sieve plate 31.

[0028] The injection molding raw materials in the storage box 2 can be screened by the sieve plate 31. Smaller particles, that is, qualified injection molding raw materials, pass through the sieve holes (not shown) of the sieve plate 31 and fall into the bottom of the inner cavity of the storage box 2 for storage, while larger particles, that is, unqualified injection molding raw materials, slide through the top of the sieve plate 31 to the crushing component 34 for crushing.

[0029] The power assembly 32 includes: a rotating shaft 322 rotatably installed on the storage box 2, a power source 321 that drives the rotating shaft 322 to rotate, a cam 323 fixedly mounted on the rotating shaft 322, a movable part 324 that reciprocates with the rotation of the cam 323, a fixed plate 325 fixedly installed in the storage box 2, and a linkage spring 326 fixedly installed between the screen plate 31 and the fixed plate 325; the movable part 324 and the screen plate 31 are hinged to each other.

[0030] The movable part 324 includes: a movable plate 3241 movably installed in the storage box 2, a rack 3242 fixedly installed on the movable plate 3241, the rack 3242 and the screen plate 31 are hingedly arranged to each other, and a reset unit 3243 is used to drive the movable plate 3241 to reset; the rack 3242 and the linkage gear 352 are meshed with each other; the reset unit 3243 includes: a slide groove opened in the storage box 2, a slider 32431 slidably installed in the slide groove, and a reset spring 32432 that drives the movable plate 3241 to reset; one end of the reset spring 32432 is fixedly connected to the slider 32431, and the other end of the reset spring 32432 is fixedly connected to the inner wall of the slide groove; the slider 32431 is fixedly connected to the movable plate 3241.

[0031] When the injection molding raw materials are screened, the power source 321 is started to drive the rotating shaft 322 to rotate, and the rotating shaft 322 drives the cam 323 to rotate. When the cam 323 rotates to abut against the movable plate 3241, the movable plate 3241 can be driven to move upward, and the movable plate 3241 drives the rack 3242 to move upward, and the rack 3242 drives the screen plate 31 to move upward. In the process of the movable plate 3241 moving upward, the slider 32431 can be driven to slide in the slide groove, and the reset spring 32432 can be driven to deform. Through the mutual cooperation between the slider 32431 and the slide groove, the movable plate 3241 can be played a role of limiting and guiding.

[0032] When the cam 323 rotates to separate from the movable plate 3241, the elastic force of the reset spring 32432 can drive the movable plate 3241 to reset downward, thereby driving the screen plate 31 to reset downward. When the cam 323 rotates, the movable part 324 can be driven to move back and forth, thereby causing the screen plate 31 to vibrate. The vibration of the screen plate 31 improves the screening efficiency of the injection molding raw materials, and avoids the injection molding raw materials from accumulating on the top of the screen plate 31 and affecting the screening efficiency.

[0033] In addition, since the vibration of the sieve plate 31 will drive the linkage spring 326 to deform, the elastic force of the linkage spring 326 causes the discharge end of the sieve plate 31 to vibrate slightly; and since the movable part 324 drives the feed end of the sieve plate 31 to vibrate with a larger amplitude, while the discharge end of the sieve plate 31 to vibrate with a smaller amplitude, the injection molding raw materials are diverted during the vibration of the sieve plate 31, and smaller particles, that is, qualified injection molding raw materials, pass through the sieve holes of the sieve plate 31 and fall into the bottom of the inner cavity of the storage box 2 for storage, and larger particles, that is, unqualified injection molding raw materials, slide through the top of the sieve plate 31 to the crushing component 34 for crushing.

[0034] It should be added here that the power source 321 is preferably a dual-axis motor.

[0035] The anti-clogging component 35 includes: an air collecting pipe 351 rotatably installed in the storage box 2, a linkage gear 352 fixedly mounted on the air collecting pipe 351, and a nozzle 353 connected to the air collecting pipe 351. The nozzle 353 is provided with a plurality of air pumps 354 which are linearly arranged along the axial direction of the air collecting pipe 351 and transport gas into the air collecting pipe 351; the linkage gear 352 and the rack 3242 are arranged to mesh with each other.

[0036] By starting the air pump 354, high-pressure gas can be delivered to the gas collecting pipe 351. The high-pressure gas is ejected through the nozzle 353 and sprayed from the discharge side of the sieve plate 31 to the feed side, thereby blowing out the injection molding material blocked in the sieve holes of the sieve plate 31, thereby avoiding the problem of the injection molding material blocking the sieve plate 31 and affecting the screening efficiency.

[0037] Furthermore, when the movable part 324 moves back and forth, since the connecting gear 352 and the rack 3242 are meshed with each other, the connecting gear 352 can be driven to rotate back and forth, and the connecting gear 352 drives the air collecting pipe 351 to rotate back and forth, and the air collecting pipe 351 drives the nozzle 353 to swing back and forth, thereby expanding the injection range of the nozzle 353, and then achieving a comprehensive cleaning of the sieve holes of the sieve plate 31, further avoiding the problem of the injection molding raw material clogging the sieve plate 31 and affecting the screening efficiency.

[0038] In the present invention, by starting the power source 321, the cam 323 can be driven to rotate, so that the movable part 324 can move back and forth, and then synchronously drive the screen plate 31 to vibrate and the nozzle 353 to swing; on the one hand, the vibration of the screen plate 31 improves the screening efficiency of the injection molding raw materials, and avoids the injection molding raw materials from accumulating on the top of the screen plate 31 and affecting the screening efficiency; on the other hand, the injection range of the nozzle 353 is expanded, and then the sieve holes of the screen plate 31 are fully cleaned, further avoiding the problem of the injection molding raw materials blocking the screen plate 31 and affecting the screening efficiency.

[0039] The feeding assembly 33 includes: a feeding hopper 331 fixedly installed in the storage box 2, a stirring blade 333 movably installed in the feeding hopper 331, a circular plate 334 coaxially connected to the stirring blade 333, and a power source 332 for synchronously driving the stirring blade 333 and the circular plate 334 to rotate, and the power source 332 is fixedly installed on the storage box 2; a feeding opening 335 connected to the feeding hopper 331 is provided on the storage box 2, a discharging opening 336 is provided on the feeding hopper 331, and a circular opening 337 matching the discharging opening 336 is provided on the circular plate 334.

[0040] When adding injection molding raw materials into the storage box 2, the injection molding raw materials are first transported to the feed hopper 331 through the feed opening 335. At the same time, the stirring shaft is driven to rotate by the power source 2 332, and the stirring shaft drives the stirring blades 333 and the circular plate 334 to rotate. Through the rotation of the stirring blades 333, the injection molding raw materials entering the feed hopper 331 can be stirred, so that the injection molding raw materials can be dispersed, thereby avoiding the problem of accumulation and agglomeration of the injection molding raw materials in the feed hopper 331, which affects the discharge efficiency.

[0041] During the rotation of the circular plate 334, the circular opening 337 on the circular plate 334 repeatedly connects with the discharge opening 336 and then staggers. When the circular opening 337 is connected with the discharge opening 336, the injection molding material in the feed hopper 331 falls to the top of the sieve plate 31 through the circular opening 337 and the discharge opening 336. When the circular opening 337 is staggered with the discharge opening 336, the injection molding material in the feed hopper 331 cannot be discharged, thereby achieving intermittent discharge of the injection molding material in the feed hopper 331, avoiding the problem of excessive injection molding material falling on the sieve plate 31 and resulting in insufficient screening, thereby ensuring the stability and efficiency of the screening process.

[0042] It is added here that the power source 2 332 is preferably an electric motor.

[0043] The crushing assembly 34 includes: a crushing box 341 fixedly installed on the storage box 2, a crushing roller 343 rotatably installed in the crushing box 341, the crushing roller 343 is provided with two power sources 342 for driving the crushing roller 343 to rotate, the power source 342 is fixedly installed on the crushing box 341, and the output shaft of the power source 342 is coaxially connected to any one of the crushing rollers 343, and a transmission gear 344 coaxially connected to the crushing roller 343, and the two transmission gears 344 are arranged to mesh with each other; the crushing box 341 is provided with opening 1 and opening 2 which are connected to the storage box 2.

[0044] The unqualified injection molding raw materials slide through the top of the sieve plate 31 to the discharge end of the sieve plate 31, and slide through the opening 1 into the crushing box 341. Two guide plates are fixedly installed on the inner wall of the crushing box 341. The two guide plates are both located above the crushing roller 343, and the two guide plates are both inclined, so that the injection molding raw materials entering the crushing box 341 can be guided between the two crushing rollers 343.

[0045] At the same time, by starting the power source three 342, the crushing roller 343 coaxially connected with its output shaft is driven to rotate, thereby driving the adjacent transmission gear 344 to rotate. Since the two transmission gears 344 are meshed with each other, the two crushing rollers 343 can rotate relatively, so that the injection molding raw materials can be crushed. The crushed injection molding raw materials fall to the bottom of the inner cavity of the crushing box 341. Since the bottom of the inner cavity of the crushing box 341 is inclined, the crushed injection molding raw materials slide to the second opening through the bottom of the inner cavity of the crushing box 341, and enter the storage box 2 through the second opening.

[0046] In the present invention, unqualified injection molding raw materials can be crushed by the crushing component 34, and the crushed injection molding raw materials can be transported to the storage box 2 for use. On the one hand, the crushing can refine the originally larger injection molding raw material particles, making it easier to evenly distribute and melt during the injection molding process, thereby improving the efficiency of injection molding; on the other hand, the crushed particles can be reused, reducing the waste of raw materials and improving the utilization rate of materials.

[0047] It is to be added here that the power source three 342 is preferably an electric motor.

[0048] The pretreatment mechanism of the present invention can realize intermittent feeding of injection molding raw materials and screening of injection molding raw materials. Unqualified injection molding raw materials can be reused after being crushed, which solves the problem that larger particles require longer time to melt and mix evenly, which easily leads to uneven melt temperature distribution and affects the uniformity and quality of injection molded parts. In addition, too large particles can easily lead to insufficient melt mixing, resulting in uneven color and inconsistent performance inside the injection molded parts.

[0049] The heat dissipation mechanism 4 includes: a processing box 42 fixedly mounted on the material storage box 2 , a fan 41 that transports hot air generated during the injection molding process of the injection molding machine 1 to the processing box 42 , and a filter assembly 43 that filters dust in the hot air entering the processing box 42 .

[0050] The injection molding machine 1 generates a large amount of heat during operation, especially in the plasticizing stage. If the heat cannot be dissipated in time, the various components of the injection molding machine 1 may be damaged due to overheating, or even cause machine failure. By starting the fan 41, the hot air generated during the injection molding process of the injection molding machine 1 can be transported to the processing box 42, thereby playing a role in dissipating the heat of the injection molding machine 1. On the one hand, it ensures that the injection molding machine 1 operates within a suitable temperature range, thereby extending the service life of the machine. On the other hand, when the injection mold is opened, the exhaust gas in the injection mold is sucked away to avoid pollution to the environment. The exhaust gas is high-temperature gas, thereby avoiding the problem of hot gas causing burns to the staff when the injection mold is opened.

[0051] It is added here that the power source 321 and the air pump 354 are both fixedly installed in the processing box 42.

[0052] The filter assembly 43 includes: a filter 431 fixedly installed in the processing box 42, a front cleaning member 432 for cleaning the air inlet side of the filter 431, a rear cleaning member 433 for cleaning the air outlet side of the filter 431, and a fan blade 434 for accelerating the air flow; the front cleaning member 432, the rear cleaning member 433, and the fan blade 434 are coaxially connected; and the front cleaning member 432, the rear cleaning member 433, and the fan blade 434 are all installed on the rotating shaft 322.

[0053] Since the injection molding raw materials will undergo high-temperature melting and injection molding during the heating and molding process, injection molding waste gas will be generated in this process, and its main components include dust particles, which will not only pollute the environment but also may harm the health of the workers; therefore, the solid impurities contained in the gas entering the processing box 42 can be filtered through the filter net 431, thereby realizing the filtration and purification of the gas and ensuring the cleanliness of the production environment.

[0054] Starting the power source 321 can drive the rotating shaft 322 to rotate, thereby driving the front cleaning member 432, the rear cleaning member 433, and the fan blade 434 to rotate. The filter 431 can be cleaned by rotating the front cleaning member 432 and the rear cleaning member 433 to avoid clogging of the filter 431 and affecting the filtering effect. The rotation of the fan blade 434 can accelerate the flow of gas, improve the gas transportation efficiency, and thus improve the gas filtering efficiency.

[0055] The front cleaning member 432 includes: a connecting shell 4321 fixedly mounted on the rotating shaft 322, a scraper 4322 movably mounted in the connecting shell 4321, a baffle 4323 fixedly mounted on the connecting shell 4321, and a connecting spring 4324 fixedly mounted between the scraper 4322 and the connecting shell 4321; the rear cleaning member 433 includes: a cleaning cylinder 4331 rotatably mounted on the rotating shaft 322, a linkage bevel gear 4332 coaxially connected to the cleaning cylinder 4331, and a bevel gear ring 4333 meshing with the linkage bevel gear 4332, the bevel gear ring 4333 being fixedly mounted in the processing box 42; a collecting box for collecting impurities is installed at the bottom of the processing box 42, and the collecting box and the processing box 42 are detachably designed, so as to facilitate the disassembly of the processing box 42 from the collecting box and facilitate the processing of impurities in the collecting box, and a collecting opening is opened on the processing box 42, and the collecting opening is connected to the collecting box.

[0056] When the rear cleaning member 433 rotates, the rotating shaft 322 drives the cleaning cylinder 4331 and the linked bevel gear 4332 to rotate along the circumferential direction of the rotating shaft 322. Since the linked bevel gear 4332 and the bevel gear ring 4333 are meshed with each other, the linked bevel gear 4332 rotates along the circumferential direction of the rotating shaft 322 and at the same time rotates on its own, thereby driving the cleaning cylinder 4331 to rotate on its own. Since the surface of the cleaning cylinder 4331 is designed with bristles, the bristles will extend into the filter holes of the filter screen 431 and push out the impurities in the filter holes. The pushed out impurities are on the outer air intake side of the filter screen 431.

[0057] By rotating the cleaning cylinder 4331 along the circumference of the rotating shaft 322 and rotating on its own, impurities in the filter hole can be pushed out, thereby achieving preliminary cleaning of the filter screen 431 and improving the filtering effect of the filter screen 431.

[0058] At the same time, when the front cleaning member 432 rotates, the rotating shaft 322 drives the connecting shell 4321 to rotate, and the connecting shell 4321 drives the scraper 4322 to rotate. The scraper 4322 can scrape away impurities attached to the air inlet side of the filter 431 and impurities pushed out of the filter hole by the bristles. Since the scraper 4322 is arranged in an arc shape, the impurities are subjected to centrifugal force as the scraper 4322 rotates, and are then guided to the discharge opening, enter the collection opening through the discharge opening, and then enter the collection box for collection, thereby realizing secondary cleaning of the filter 431, greatly improving the cleaning effect, and further improving the filtering effect of the filter 431.

[0059] By setting the connecting spring 4324 , the scraper 4322 can always fit the filter screen 431 , avoiding the scraper 4322 from being separated from the filter screen 431 , thereby improving the cleaning effect of the scraper 4322 on the filter screen 431 .

[0060] By setting the baffle 4323, when the impurities are subjected to the centrifugal force as the scraper 4322 rotates, the impurities are shielded, which is beneficial to the collection of the impurities and improves the cleaning efficiency of the impurities.

[0061] By setting the front cleaning member 432 and the rear cleaning member 433, the filter 431 can be double cleaned, thereby improving the cleaning effect, thereby improving the filtering effect of the filter 431, and preventing impurities from clogging the filter 431 and affecting the ventilation effect.

[0062] It also includes: a rotating tube 5 rotatably installed in the storage box 2, a linkage tube 6 connected to the rotating tube 5, a driven bevel gear 8 fixedly sleeved on the rotating tube 5, and a driving bevel gear 7 meshingly connected to the driven bevel gear 8; the driving bevel gear 7 is coaxially connected to the cam 323, the rotating tube 5 is connected to the air pump 354, and a plurality of air injection holes 9 are opened on the linkage tube 6.

[0063] The high-temperature gas in the processing box 42 is transported to the rotating tube 5 through the air pump 354, flows through the interlocking tube 6, and is ejected through the jet hole 9, so that the qualified injection molding raw materials can be preheated. The temperature of the preheated injection molding raw materials increases, so that the heating time required in the injection molding process will be reduced, thereby accelerating the production speed and shortening the production cycle.

[0064] At the same time, when the power source 321 drives the rotating shaft 322 to rotate, it can drive the active bevel gear 7 to rotate, the active bevel gear 7 drives the driven bevel gear 8 to rotate, the driven bevel gear 8 drives the rotating tube 5 to rotate, and the rotating tube 5 drives the interlocking tube 6 to rotate. Through the rotation of the interlocking tube 6, the qualified injection molding raw materials can be stirred, so that the injection molding raw materials are heated evenly, thereby improving the preheating effect of the injection molding raw materials.

[0065] In the present invention, the filtered hot air is respectively transported to the collecting pipe 351 and the connecting pipe 6 through the air pump 354. On the one hand, the injection molding material blocked in the sieve holes of the sieve plate 31 can be blown out, thereby avoiding the problem of the injection molding material blocking the sieve plate 31 and affecting the screening efficiency. On the other hand, the qualified injection molding material can be preheated. The temperature of the preheated injection molding material increases, so that the heating time required in the injection molding process will be reduced, thereby accelerating the production speed and shortening the production cycle.
