[0039] The traditional way of feeding for the secondary injection molding is manual feeding, which has low work efficiency. Therefore, a feeding method using a mechanical hand is provided, which needs the mechanical hand to take materials at a predetermined position for feeding. However, the feeding of the secondary injection molding workpiece after the injection molding is still needed to be manually taken, and if automatic taking is needed, an additional mechanical hand needs to be provided, which not only occupies the space of the site, but also increases the cost of the equipment. Moreover, it cannot be applied to the scenario of confirming the placement angle of the semi-finished workpiece and then aligning and placing it into the mold, and can only be completed by manual work, which has limited application scenarios and low work efficiency.

[0040] Therefore, the present application provides a feeding and sorting system, which aims to solve the problem of low production efficiency caused by manual confirmation of the placement angle of the semi-finished workpiece.

[0041] Reference Figure 1 In the embodiment of the present application, the feeding and sorting system 300 comprises a rack 310, a feeding mechanism 400, a material arranging mechanism 600, a material moving mechanism 700 and a positioning mechanism 500, the feeding mechanism 400 is installed on the rack 310, the material arranging mechanism 600 is installed on the rack 310 and located below the material outlet 411 of the feeding mechanism 400, and the positioning mechanism 500 is installed on the rack 310.

[0042] The feeding and sorting system 300 can be used alone to solve the problem of a large number of semi-finished workpieces 10 that need to be placed, for example, to solve the problem that the semi-finished workpieces 10 are placed in a taking tray by manual operation in the traditional way, or to solve the problem of high cost of placing the semi-finished workpieces 10 in a taking tray by using a mechanical hand. That is, in some scenarios, the feeding and sorting system 300 can be used for the classification and placement of semi-finished workpieces 10, or can be used in combination with an injection molding machine to improve production efficiency, etc.

[0043] Specifically, the positioning mechanism 500 comprises a moving assembly 510 movable relative to the rack 310, a jacking and loading assembly 520 mounted on the moving assembly 510, and a rotating positioning assembly 550 located above the jacking and loading assembly 520, the jacking and loading assembly 520 being located at a discharging position 411 of the discharging mechanism 600; the material moving mechanism 700 is mounted on the rack 310, wherein the moving assembly 510 is movable relative to the rack 310 to have a discharging position below the rotating positioning assembly 550 and a material taking position for the material moving mechanism 700 to move materials, the feeding mechanism 400 is used to transport a material stack to be arranged into the discharging mechanism 600, the discharging mechanism 600 discharges the material stack into ordered single materials and sequentially feeds the ordered single materials to the jacking and loading assembly 520, the rotating positioning assembly 550 clamps and rotates a single material, the jacking and loading assembly 520 lifts and holds the single material, the moving assembly 510 drives the jacking and loading assembly 520 to the material taking position, the material moving mechanism 700 takes the single material from the jacking and loading assembly 520 and sequentially discharges the single material in a preset material taking area.

[0044] The traditional way of secondary injection molding feeding is manual feeding, which is low in work efficiency. Therefore, a mechanical hand is used for feeding. This method needs the mechanical hand to take materials at a predetermined position for feeding. However, the secondary injection molding workpiece after injection molding needs manual taking. If automatic taking is needed, an additional mechanical hand needs to be set, which occupies space and increases the cost of equipment. Moreover, it cannot be applied to the scene of confirming the placement angle of the semi-finished workpiece 10 and then aligning and placing it in the mold. It can only be completed by manual work, which is limited in application and low in work efficiency.

[0045] Reference Figures 2 to 6 To solve the problem that the placement angle of the semi-finished workpiece 10 needs to be confirmed and completed manually, which is low in production efficiency, the present embodiment solves the problem by setting a feeding and sorting system 300. Specifically, the feeding and sorting system 300 is arranged adjacent to the injection molding machine, and the feeding and sorting system 300 comprises a rack 310, a feeding mechanism 400, a discharging mechanism 600, a positioning mechanism 500, and a material moving mechanism 700 located on the rack 310. The feeding mechanism 400 is used to transport a large number of semi-finished workpieces 10 to be arranged into the discharging mechanism 600. The discharging mechanism 600 discharges a large number of semi-finished workpieces 10 into ordered single semi-finished workpieces 10. The positioning mechanism 500 is used to sort the single semi-finished workpieces 10 at a certain angle. The material moving mechanism 700 is used to sequentially discharge the single semi-finished workpieces 10 sorted by the positioning mechanism 500 in a preset material taking area.

[0046] In operation, a worker introduces a large number of semi-finished workpieces 10 to be arranged into the feeding mechanism 400, and the feeding mechanism 400 sends the large number of semi-finished workpieces 10 to be arranged into the discharging mechanism 600. The discharging mechanism 600 discharges the large number of semi-finished workpieces 10 into ordered single semi-finished workpieces 10. The discharging mechanism 600 can be a discharging mechanism 600 commonly used in the injection molding industry, such as a conveying belt discharging mechanism, a roller discharging mechanism, a vibrating disc discharging mechanism, etc. Compared with the traditional manual handling of semi-finished workpieces 10 to the discharging mechanism 600 for discharging, the efficiency is greatly improved, and the labor cost and work intensity are reduced. The discharging mechanism 600 sends the ordered single semi-finished workpieces 10 to the positioning mechanism 500. The positioning mechanism 500 is used to position the single semi-finished workpieces 10 at an angle. In other words, the positioning mechanism 500 places a semi-finished workpiece 10 at a specific angle. Taking the toy wheel core of the present embodiment as an example, the wheel core needs to be placed at an angle to avoid processing failure in the secondary injection molding process. After the positioning mechanism 500 places the semi-finished workpiece 10 conveyed from the discharging mechanism 600 at a predetermined angle, the material moving mechanism 700 moves the semi-finished workpiece 10 to a predetermined material taking area by suction or clamping. The positioning mechanism 500 and the material moving mechanism 700 repeat the process until the material moving mechanism 700 fills the material taking area with the angled semi-finished workpieces 10. The three-axis robot takes the semi-finished workpieces 10 for secondary injection molding. Compared with the traditional manual confirmation of the placement angle of the semi-finished workpieces 10 and then the positioning into a tray, the work efficiency is improved, and the labor cost is reduced.

[0047] Reference Figures 2 to 6 , the specific structure of the upper sorting system, the functions that can be achieved.

[0048] Reference Figure 2 The feeding and sorting system 300 includes a rack 310, a feeding mechanism 400, a discharging mechanism 600, a positioning mechanism 500, and a material moving mechanism 700. In the existing secondary injection molding process, the semi-finished workpieces 10 need to be manually discharged during the feeding process, and the placement angle of the semi-finished workpieces 10 needs to be adjusted. This results in high labor intensity, low work efficiency, and high labor cost. The feeding mechanism 400 and the discharging mechanism 600 can sort a large number of semi-finished workpieces 10 at one time, improving the efficiency. The positioning mechanism 500 positions the angle of the discharged semi-finished workpieces 10, and the material moving robot 720 loads the tray into the positioning jig 730 to solve the problem.

[0049] The feeding and sorting system 300 can be used alone to solve the problem of a large number of semi-finished workpieces 10 that need to be placed, for example, to solve the problem that the semi-finished workpieces 10 are placed in the feeding tray by traditional tray placement, which can only be operated manually, or the problem that the semi-finished workpieces 10 are placed in the feeding tray by a mechanical hand, which has a high cost. That is, in some scenarios, the feeding and sorting system 300 can be used for the classification and placement of semi-finished workpieces 10; or it can be used in combination with the injection molding machine 100 to improve production efficiency, etc.

[0050] In an embodiment, the feeding mechanism 400 can be a mechanical hand feeding, a conveying table feeding, a transmission belt feeding, etc.

[0051] Referring to Figure 2 and Figure 3 In this embodiment, in order to facilitate miniaturization of the equipment and reduce the cost of the equipment, the feeding mechanism 400 includes a feeding rack 410 extending in the height direction of the rack 310, a feeding hopper 420 located on one side of the feeding rack 410 and in sliding connection with the feeding rack 410, a feeding drive mechanism 430 driving the feeding hopper 420 to move, and a discharging hopper 440 located on the other side of the feeding rack 410. The feeding rack 410 is installed on the rack 310, and the feeding rack 410 is provided with a material position opening 411 located above the discharging mechanism 600. The discharging hopper 440 corresponds to the material position opening 411. The feeding hopper 420 is used to place a material pile, the feeding drive mechanism 430 can drive the feeding hopper 420 to move to the material position opening 411, and the material pile falls from the discharging hopper 440 into the discharging mechanism 600 through the material position opening 411.

[0052] The feeding rack 410 is made of metal or non-metal and has a certain strength. The feeding rack 410 as a whole is like a door panel, and the material position opening 411 is formed in the middle of the upper portion. In order to avoid material accumulation and ensure smooth discharging, the bottom of the discharging hopper 440 is inclined toward the direction of the material position opening 411. The discharging hopper 440 is in sliding connection with the edges of the two sides of the feeding rack 410 through a sliding block guide rail assembly. The feeding drive mechanism 430 is a lifting motor. The lifting motor drives the sliding block guide rail assembly through a synchronous belt assembly, so that the discharging hopper 440 can move in the height direction of the feeding rack 410 to the material position opening 411. The material in the discharging hopper 440 enters the material position opening 411 under the action of gravity from the inclined bottom. The discharging passage of the discharging hopper 440 is closed to prevent the material from flying out. The inclination direction of the bottom of the discharging hopper 440 is the same as that of the discharging hopper 440, so that the material entering the discharging hopper 440 can smoothly enter the discharging mechanism 600, avoiding material accumulation. The feeding mechanism 400 occupies space in the height direction. Compared with other feeding methods that transport a large number of semi-finished workpieces 10 to the discharging mechanism 600, the feeding mechanism 400 has the advantages of reducing the working intensity of workers, reasonably utilizing space, facilitating miniaturization of the equipment, and simple structure and low cost.

[0053] Referring to Figure 2 and Figure 3 Further, in order to realize automatic replenishment of materials without manual operation, a pair of photoelectric switch sensors 450 are arranged on the discharge hopper 440 to detect the material condition in the discharge hopper 440, and when the discharge hopper 440 has materials, the feeding driving mechanism 430 is not started, and on the contrary, the feeding driving mechanism 430 drives the feeding hopper 420 to move for replenishment.

[0054] Referring to Figure 1 Further, an alarm indicator 460 is arranged to prompt replenishment of materials or to remind that the materials are insufficient, such as the scenario that the feeding driving mechanism 430 drives the feeding hopper 420 to move for replenishment, to prompt replenishment of materials or to remind that the materials are insufficient, so that a dedicated person does not need to keep an eye on it at all times, improving convenience.

[0055] Referring to Figure 1 and Figure 2 Further, in order to realize that when the discharging mechanism 600 has enough semi-finished workpieces 10, the feeding mechanism 400 stops to continue to transport materials to the discharging mechanism 600, avoiding accumulation of semi-finished workpieces 10, the feeding mechanism 400 further comprises a material limiting mechanism 470, the material limiting mechanism 470 comprises a double-shaft pneumatic cylinder 471 mounted on the rack 310, a photoelectric switch sensor 473 mounted on the double-shaft pneumatic cylinder 471, and a baffle 472 connected with the driving shaft of the double-shaft pneumatic cylinder 471, the photoelectric switch sensor 473 is used to detect the material condition in the discharging mechanism 600, and the double-shaft pneumatic cylinder 471 drives the baffle 472 to approach or move away from the opening of the discharge hopper 440 under the control of the photoelectric switch sensor 473.

[0056] It is worth mentioning that the baffle 472 of the material limiting mechanism 470 can not only be quickly responded by the double-shaft pneumatic cylinder 471 to effectively close the discharge opening of the discharge hopper 440 to prevent materials from continuing to enter the discharging mechanism 600, but also can buffer the speed of the materials entering the discharging mechanism 600 at the discharge opening of the discharge hopper 440, so that the materials can accurately fall into the discharging mechanism 600 without the need for additional blocking components or modification of the equipment, optimizing the structure and reducing the cost.

[0057] The feeding mechanism 400 is matched with the discharging mechanism 600, and is suitable for occasions where a large amount of materials need to be sorted and sequenced, and in an embodiment, the discharging mechanism 600 can be a discharging mechanism 600 commonly used in the injection molding industry, such as a conveying belt discharging mechanism, a roller discharging mechanism, a vibrating disc discharging mechanism, etc.

[0058] In the embodiment, in order to facilitate the miniaturization of the device and reduce the cost of the device, the discharging mechanism 600 is a vibrating disc, and the lifting and loading assembly 520 is flush with the discharging height of the discharging port 411 of the vibrating disc. The specific structure of the vibrating disc can refer to the existing vibrating disc, and will not be described here.

[0059] In order to arrange the large number of semi-finished workpieces 10 into ordered single semi-finished workpieces 10 by the discharging mechanism 600, it is necessary to arrange the single semi-finished workpieces 10 at a certain angle and arrange the arranged semi-finished workpieces 10 one by one in the preset material taking area. This is achieved by the positioning mechanism 500 and the material moving mechanism 700. The positioning mechanism 500 is used to arrange the single semi-finished workpieces 10 at a certain angle, and the material moving mechanism 700 is used to arrange the single semi-finished workpieces 10 arranged by the positioning mechanism 500 one by one in the preset material taking area.

[0060] Referring to Figure 4 and Figure 5 , further, in order to facilitate the miniaturization of the device and reduce the cost of the device, the positioning mechanism 500 includes a moving assembly 510 movable relative to the rack 310, a lifting and loading assembly 520 mounted on the moving assembly 510, and a rotary positioning assembly 550 located above the lifting and loading assembly 520. The lifting and loading assembly 520 is located at the discharging port 411 of the discharging mechanism 600, and the lifting and loading assembly 520 and the rotary positioning assembly 550 are used to arrange the single material at a certain angle. The moving assembly 510 moves relative to the rack 310 and has a discharging position below the rotary positioning assembly 550 and a material taking position for the material moving mechanism 700 to move the material. Compared with manually confirming the angle of the semi-finished workpieces 10 and then positioning them in the tray, this improves work efficiency and reduces labor costs. Compared with using a mechanical hand to arrange the angle of the semi-finished workpieces 10, it has the advantages of reasonable use of space, facilitation of miniaturization of the device, simple structure and low cost.

[0061] Referring to Figure 5 , specifically, the moving assembly 510 includes a driving cylinder 511 and a moving table 512 connected with the driving shaft of the driving cylinder 511. The two ends of the moving table 512 are movably mounted on two movable rods. The driving cylinder 511 is used to control the stroke, the response speed is fast, the control device cost is low, and in other embodiments, a motor screw pair assembly, a motor synchronous belt assembly, etc. can also be used.

[0062] Referring to Figure 5, specifically, the rotating positioning assembly 550 comprises a rotating mount 551, a jaw mechanism 552 arranged on the mount, the lifting loading assembly 520 is located in the rotating mount 551 and below the jaw mechanism 552, the jaw mechanism 552 comprises a motor and a jaw connected with the motor.

[0063] With reference to Figure 5 , specifically, the lifting loading assembly 520 comprises a lifting cylinder 521 connected with the moving platform 512, a material mounting assembly 530 connected with a driving shaft of the lifting cylinder 521.

[0064] With reference to Figure 5 , specifically, the material mounting assembly 530 comprises a mounting piece 531, a material placing platform 532, and a buffer mechanism 540 between the mounting piece 531 and the material placing platform 532, the mounting piece 531 has a guide port, the buffer mechanism 540 comprises a guide rod 541 connected with the material placing platform 532 and a buffer spring 542 on the guide rod 541, the guide rod 541 is arranged in the guide port, the lifting cylinder 521 drives the mounting piece 531 to move, the mounting piece 531 drives the buffer spring 542 to drive the material placing platform 532, when stressed, the material placing platform 532 moves to the direction close to the mounting piece 531 through the two guide rods 541.

[0065] With reference to Figure 5 , further, in order to ensure that the material can be accurately dropped on the material placing platform 532 and facilitate the lifting loading assembly 520 to lift for the jaw mechanism 552 to clamp, the positioning mechanism 500 further comprises a blocking strip 553, the blocking strip 553 is arranged on the side of the mounting piece 531 or the material placing platform 532 away from the material discharging port 411.

[0066] When working, the semi-finished workpiece 10 fed from the vibrating disc falls into the material placing table 532 through the inertia of the conveying channel. The blocking strip 553 is arranged on the mounting member 531 or the material placing table 532 away from the side of the discharge port 411, so as to block the continuous movement of the semi-finished workpiece 10 and make it fall into the material placing table 532. The material placing table 532 has a mounting clamping groove corresponding to the semi-finished workpiece 10. The mounting member 531 drives the buffer spring 542 to drive the material placing table 532 to be close to the clamping jaw mechanism 552. The clamping jaw of the clamping jaw mechanism 552 clamps the semi-finished workpiece 10 and rotates under the drive of the motor, so that the semi-finished workpiece 10 can fall into the mounting clamping groove and be sorted at an angle. In order to avoid damage to the semi-finished workpiece 10, when being stressed, the material placing table 532 moves to the side close to the mounting member 531 through the two guide rods 541, so as to buffer the impact force when the material mounting assembly 530 contacts the clamping jaw, realize flexible grabbing and placing, and avoid damaging the workpiece. When the semi-finished workpiece 10 is placed at a good angle on the material placing table 532, the movable mounting table 512 is movably mounted on the two movable rods. The drive cylinder 511 drives the movable mounting table 512 to move to the material taking position relative to the two movable rods, so as to take out the semi-finished workpiece 10 from the material placing table 532.

[0067] After the conveying single material of the discharging mechanism 600, the positioning mechanism 500 needs to place and convey the single material at an angle. In order to avoid the need for manual control of the opening and closing of the discharging mechanism 600 and to reduce the cost of the equipment, in the embodiment, a mechanical mode is adopted to realize that the remaining semi-finished workpieces 10 on the discharging mechanism 600 do not enter the positioning mechanism 500, so as to avoid the functional disorder. In the embodiment, the positioning mechanism 500 further comprises a limiting mechanism 560. The limiting mechanism 560 comprises a limiting cylinder 561 connected to the side of the rotating mounting frame 551 close to the discharge port 411 and a limiting strip 562 connected to the drive shaft of the limiting cylinder 561. The limiting strip 562 can be close to or away from the discharge port 411 under the drive of the limiting cylinder 561.

[0068] With reference to Figure 5 , specifically, when the single semi-finished workpiece 10 enters the material placing table 532, the limiting strip 562 is close to the discharge port 411 under the drive of the cylinder, so as to block the next semi-finished workpiece 10 from entering the material placing table 532. After the semi-finished workpiece 10 on the material placing table 532 is taken out and returned, the limiting strip 562 is away from the discharge port 411 under the drive of the cylinder, so that the next semi-finished workpiece 10 enters the material placing table 532.

[0069] It should be noted that when the discharging mechanism 600 and the positioning mechanism 500 are used alone, the material moving mechanism 700 can be manually or by a mechanical hand. In order to improve the efficiency and reduce the labor cost and equipment cost, in the embodiment, the material moving mechanism 700 includes a material moving slide rail 710 mounted on the rack 310, and a material moving mechanical hand 720 slidingly mounted on the material moving slide rail 710, and the material moving mechanical hand 720 can move between the material placing position and the material taking position. Compared with the mechanical hand for taking the material from the material placing table 532, because the material moving mechanism 700 only moves in one direction in the embodiment, the device structure is compact and the cost is reduced.

[0070] With reference to Figure 6 Further, in order to improve the production efficiency and facilitate the automation of the device, the feeding and sorting system 300 further includes a positioning jig 730 arranged in the preset area, the positioning jig 730 includes a jig rack 731 and mounting portions 733 arranged in sequence on the jig rack 731, and the material moving mechanism 700 places the single semi-finished workpiece 10 on one of the mounting portions 733. The three-axis mechanical hand 200 mentioned above takes the placed semi-finished workpiece 10 from the positioning jig 730 and puts it into the injection molding machine 100 for secondary injection molding processing.

[0071] It should be noted that when not used with the injection molding machine 100, the positioning jig 730 can be replaced by a material placing disc for placing the semi-finished workpiece 10, and the placed material placing disc is replaced by a new material placing disc by manual or mechanical operation to realize the arrangement of the material.

[0072] Further, in order to overcome the problem of insufficient material arrangement caused by the material moving mechanism 700 being able to place in only one direction, the feeding and sorting system 300 further includes a jig table 732 and a jig driving cylinder 511, the jig table 732 and the jig rack 731 are connected by a slide rail, and the jig driving cylinder 511 is connected to the jig rack 731 by a connecting piece to drive the jig rack 731 to move close to or away from the material moving mechanism 700. In this way, the problem of insufficient material arrangement caused by the material moving mechanism 700 being able to place in only one direction is solved, and multiple rows can be placed to improve the production efficiency, and compared with the mechanical hand for placing multiple rows, the cost is lower. In the embodiment, the jig rack 731 is provided with two rows of mounting portions 733 arranged in sequence, which are suitable for the mold of the injection molding machine 100. In other embodiments, the jig rack 731 can be provided with more than two rows of mounting portions 733.

[0073] With reference to Figure 6Further, the jig table 732 is driven by the jig driving cylinder 511, compared with the motor and screw assembly, gear assembly and the like, the cost is lower, the structure is simpler, in order to make the jig table 732 stroke more accurate, thereby guarantee the efficiency of the material moving mechanism 700, the jig table 732 is arranged on the relative both sides of the moving direction of the jig frame 731 with a positioning adjusting mechanism, the positioning adjusting mechanism includes the adjusting table connected with the jig table 732, the limiting adjusting piece 740 can be adjusted along the moving direction of the jig frame 731.

[0074] In the embodiment, the limiting adjusting piece 740 is a hexagonal screw.

[0075] Further, in order to buffer the impact force of the jig table 732 driven by the jig driving cylinder 511, prolong the service life of the equipment and avoid the damage to the semi-finished workpiece 10, in the embodiment, the adjusting table is also provided with a buffer 750, the buffer 750 is spaced apart from the limiting adjusting piece 740, the end of the buffer 750 contacts the jig frame 731 earlier than the limiting adjusting piece 740.

[0076] In other embodiments, the purpose of buffering can also be achieved by reducing the moving speed of the jig table 732 on the slide rail of the jig table 732 and the jig frame 731, such as spring and the like.

[0077] In other embodiments, the limiting adjusting piece 740 can also be combined with the buffer 750 together.

[0078] When working, because the feeding frame 410 is arranged along the height direction of the rack 310, compared with other types of feeding mechanisms 400, the discharge hopper 440 at the initial position is at the bottom of the feeding frame 410, a large number of semi-finished workpieces 10 can be easily put into the feeding hopper 420, the feeding hopper 420 rises to the material position 411, the semi-finished workpieces 10 slide out from the discharge hopper 440 by inertia, the semi-finished workpieces 10 fall into the discharging mechanism 600, the semi-finished workpieces 10 with too high speed are blocked by the baffle 472 of the limiting mechanism 470 to avoid flying out, the sorted semi-finished workpieces 10 enter the positioning mechanism 500 for angle sorting, the material moving mechanism 700 arranges the single semi-finished workpieces 10 sorted by the positioning mechanism 500 on the positioning jig 730 in the preset material taking area one by one, the positioning jig 730 moves back and forth by air cylinder driving, so that the material moving mechanism 700 can arrange the semi-finished materials into two columns for the first suction assembly 260 of the material taking assembly 250 to put into the injection molding machine 100, the discharge hopper 440 is also provided with a pair of photoelectric switch sensors 450, when the discharge hopper 440 has materials, the feeding driving mechanism 430 does not start, on the contrary, the feeding driving mechanism 430 drives the feeding hopper 420 to move for replenishment. The alarm indicator light 460 prompts to replenish materials or reminds that the materials are insufficient, for example, in the case that the feeding driving mechanism 430 drives the feeding hopper 420 to move for replenishment, the alarm indicator light 460 prompts to replenish materials or reminds that the materials are insufficient, so that it is not necessary to keep an eye on all the time, and the convenience is improved. The limiting mechanism 470 comprises a photoelectric switch sensor 473 mounted for detecting the material condition in the discharging mechanism 600. In this way, when the semi-finished workpieces 10 in the discharging mechanism 600 are insufficient, the baffle 472 is withdrawn, and the discharge hopper 440 continues to discharge materials, when the semi-finished workpieces 10 in the discharge hopper 440 are insufficient, the feeding hopper 420 continues to lift to replenish the semi-finished workpieces 10, thereby solving the problem that the placement angle of the semi-finished workpieces 10 needs to be confirmed and needs to be completed manually, and the production efficiency is low. The automatic feeding, discharging, placing and feeding processes in the secondary injection molding process are realized.

[0079] The application also provides an injection molding equipment, which comprises an injection molding machine (not shown in the figure) and the feeding and sorting system 300, and the specific structure of the feeding and sorting system 300 is as described above. Since the injection molding equipment adopts all the technical solutions of the above-mentioned embodiments, at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments are achieved, and the details are not repeated here. The injection molding machine is arranged adjacent to the feeding and sorting system 300. Compared with the traditional manual mold feeding scheme for the injection molding machine, the feeding and sorting system 300 matched with the injection molding machine can save labor, reduce the working intensity, and improve the injection molding efficiency. The work of sorting and placing a large number of semi-finished products by manual work is completed by the feeding and sorting system 300, and the workers only need to complete the subsequent feeding work or the mechanical hand completes the subsequent feeding work.
