Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to a material conveying mechanism for injection molding process of injection molding machine. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment used to make various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. When an injection molding machine is working, a material feeding mechanism is required for the injection molding process.

[0003] Existing injection molding machines use a feeding mechanism that pushes plastic through spiral blades to feed it. However, in actual use, the lack of a quantitative feeding structure when the plastic is injected from the discharge pipe into the injection molded part leads to situations where the amount of plastic used is too much or too little, resulting in reduced quality of the injection molded part. Furthermore, the lack of a filtration structure in existing feeding mechanisms allows impurities to fall into the injection molding machine along with the plastic, resulting in low overall efficiency.

[0004] Therefore, addressing the issues of existing injection molding machine material feeding mechanisms lacking a quantitative feeding structure for plastic, leading to over- or under-material situations and reduced quality of molded parts, and the lack of a filtration structure for plastic in existing feeding mechanisms causing impurities to be mixed into the plastic, thus reducing overall work efficiency, this invention utilizes a servo motor. The first gear drives the second gear to rotate, causing the control frame to rotate and pull the rotating plate. This allows the control plate to synchronously follow the connecting block and slide along the connecting groove, achieving quantitative feeding of the material from the discharge pipe. Simultaneously, the filter screen filters the plastic, preventing impurities from falling into the injection molding machine and thus reducing product quality. Utility Model Content

[0005] To overcome the common problem that the feeding mechanism of injection molding machines lacks a quantitative feeding structure for plastic, resulting in excessive or insufficient material during operation and reduced quality of injection molded parts, and to address the issue that the existing feeding mechanism lacks a plastic filtration structure, allowing impurities to be mixed into the plastic and reducing overall work efficiency.

[0006] The technical solution of this utility model is as follows: a material conveying mechanism for injection molding process of injection molding machine, including a mounting base; a fixing plate is installed on the right side of the upper end of the mounting base, a material conveying pipe is installed on the left end of the fixing plate, a drive motor is installed on the left end of the material conveying pipe, the output end of the drive motor extends to the inner side of the material conveying pipe, a transmission rod is installed on the output end of the drive motor, a spiral blade is installed on the surface of the transmission rod, a feeding seat is installed on the upper end of the material conveying pipe, a discharge pipe is installed on the lower end of the material conveying pipe, a discharge seat is installed on the upper end of the mounting base below the material conveying pipe, a guide plate is installed on the inner side of the discharge seat, a connecting pipe is installed on the bottom of the inner side of the discharge seat, and a control plate is provided on the surface of the upper end of the discharge seat.

[0007] Preferably, the upper end of the feeding seat is rotatably connected to a cover plate via a hinge, and a positioning plate is installed on the inner side of the feeding seat. Four positioning plates are provided, and a slide rod is slidably connected in the positioning plate. A connecting plate is installed on the upper end of the slide rod, and a spring is sleeved on the surface of the slide rod. A filter screen rod is attached to the upper end of the connecting plate.

[0008] Preferably, the surface of the feeding seat is provided with positioning grooves, and four positioning grooves are provided. Positioning blocks are slidably connected in the positioning grooves. A limit plate is installed at one end of the positioning block, and a limit frame is installed at the other end of the positioning block. The limit plate and the slide rod are fixedly connected, and a sliding plate is installed at the upper end of the limit frame.

[0009] Preferably, servo motors are installed on the left and right sides of the fixed plate behind the feed pipe. The output end of the servo motor extends to the right side of the fixed plate, and a first gear is installed on the output end of the servo motor. A connecting shaft is installed in the fixed plate, a second gear is installed at one end of the connecting shaft, and a control frame is installed at the other end of the connecting shaft. The second gear and the first gear are meshed together.

[0010] Preferably, a connecting rod is mounted on the surface of the control frame, a rotating plate is rotatably connected to the surface of the connecting rod, a rotating seat is mounted at the rear end of the control plate, and the rotating seat and the rotating plate are rotatably connected.

[0011] Preferably, the surface of the fixing plate is provided with a sliding groove, and a slide rail is installed in the sliding groove. There are two slide rails, and a slider is slidably connected to the surface of the slide rail. A fixing block is fixedly installed between the two sliders.

[0012] Preferably, the surface of the fixing plate is provided with a connecting groove, the connecting groove is connected to the sliding groove, a connecting block is slidably connected in the connecting groove, one end of the connecting block is fixedly connected to the control plate, and the other end of the connecting block is fixedly connected to the fixing block.

[0013] The beneficial effects of this utility model are:

[0014] 1. When the material conveying mechanism is working, the first gear can be driven to rotate under the action of the servo motor. During the rotation of the first gear, the second gear that is meshed with it will rotate. Under the action of the connecting shaft, the control frame will be rotated. Then, the connecting rod will pull the rotating plate, so that the rotating plate will pull the rotating seat synchronously. This will drive the control plate to slide synchronously along the connecting groove direction with the connecting block, and synchronously drive the slider to slide back and forth along the slide rail direction. This will achieve quantitative feeding of the discharge tube and avoid the problem of excessive or insufficient material during the operation of the injection molding machine, which will lead to a decrease in product quality.

[0015] 2. The filter screen filters impurities from the plastic before feeding. When there are too many impurities on the filter screen, the filter screen presses the connecting plate and simultaneously compresses the spring, causing the limit plate to slide along the positioning groove, thereby moving the limit frame and raising or lowering the slide plate. This helps remind workers to clean the filter screen and avoids clogging caused by excessive impurities, which would reduce overall work efficiency. Attached Figure Description

[0025] Please see Figures 1-7 This utility model provides a technical solution: a material conveying mechanism for injection molding process of an injection molding machine, including a mounting base 1; a fixing plate 2 is installed on the right side of the upper end of the mounting base 1, a material conveying pipe 3 is installed on the left end of the fixing plate 2, a drive motor 4 is installed on the left end of the material conveying pipe 3, the output end of the drive motor 4 extends to the inner side of the material conveying pipe 3, a transmission rod 41 is installed on the output end of the drive motor 4, a spiral blade 42 is installed on the surface of the transmission rod 41, a feeding seat 5 is installed on the upper end of the material conveying pipe 3, a discharge pipe 6 is installed on the lower end of the material conveying pipe 3, a discharge seat 7 is installed on the upper end of the mounting base 1 below the material conveying pipe 3, a guide plate 71 is installed on the inner side of the discharge seat 7, a connecting pipe 72 is installed on the bottom of the inner side of the discharge seat 7, and a control plate 73 is provided on the surface of the upper end of the discharge seat 7.

[0026] The upper end of the feeding seat 5 is rotatably connected to the cover plate 51 via a hinge. The inner side of the feeding seat 5 is equipped with a positioning plate 52, and there are four positioning plates 52. A slide rod 53 is slidably connected in the positioning plate 52. A connecting plate 54 is installed at the upper end of the slide rod 53. A spring 55 is sleeved on the surface of the slide rod 53. A filter screen 8 is attached to the upper end of the connecting plate 54. Under the action of the filter screen 8, the plastic is filtered to prevent impurities from falling into the conveying pipe 3 and causing a reduction in product quality.

[0027] The surface of the feeding seat 5 is provided with positioning grooves 501, and there are four positioning grooves 501. Positioning blocks 502 are slidably connected in the positioning grooves 501. A limit plate 503 is installed at one end of the positioning block 502, and a limit frame 504 is installed at the other end of the positioning block 502. The limit plate 503 and the slide rod 53 are fixedly connected. A slide plate 505 is installed at the upper end of the limit frame 504. By opening the positioning grooves 501, the limit plate 503 can synchronously drive the positioning block 502 to move in the positioning grooves 501, thereby driving the limit frame 504 to move. This allows the slide plate 505 to move up and down synchronously, which is convenient for reminding the operator to replace the filter screen 8 and avoid the filter screen 8 from becoming clogged.

[0028] Servo motors 9 are installed on the left and right sides of the fixed plate 2, which are located behind the material conveying pipe 3. The output end of the servo motor 9 extends to the right side of the fixed plate 2. A first gear 91 is installed on the output end of the servo motor 9. A connecting shaft is installed in the fixed plate 2. A second gear 92 is installed on one end of the connecting shaft, and a control frame 10 is installed on the other end of the connecting shaft. The second gear 92 and the first gear 91 are meshed and connected. Under the action of the servo motor 9, the first gear 91 rotates, which synchronously drives the meshed second gear 92 to rotate during the rotation of the first gear 91, providing power for subsequent quantitative feeding.

[0029] A connecting rod 101 is mounted on the surface of the control frame 10, and a rotating plate 102 is rotatably connected to the surface of the connecting rod 101. A rotating seat 74 is mounted on the rear end of the control plate 73, and the rotating seat 74 and the rotating plate 102 are rotatably connected.

[0030] The surface of the fixed plate 2 is provided with a groove 21, and a slide rail 22 is installed in the groove 21. There are two slide rails 22, and a slider 23 is slidably connected to the surface of the slide rail 22. A fixing block 24 is fixedly installed between the two sliders 23. By opening the groove 21, the slider 23 slides along the direction of the slide rail 22, so as to synchronously drive the fixing block 24 to slide in the groove 21.

[0031] The surface of the fixed plate 2 is provided with a connecting groove 201, which is connected to the slide groove 21. A connecting block 202 is slidably connected in the connecting groove 201. One end of the connecting block 202 is fixedly connected to the control plate 73, and the other end of the connecting block 202 is fixedly connected to the fixed block 24. By providing the connecting groove 201, the connecting block 202 slides in the connecting groove 201 while simultaneously driving the fixed block 24 to slide in the slide groove 21, thus completing the reciprocating motion of the control plate 73 and realizing the quantitative feeding operation of the discharge pipe 6, avoiding the problem of reduced product quality caused by excessive or insufficient material usage in the injection molding machine.

[0032] Working principle: According to Figures 1-5When the material conveying mechanism is loading, the cover plate 51 can be opened by the hinge and the plastic can be injected into the loading seat 5. Then, under the action of the filter screen 8, the plastic is filtered to prevent impurities from falling into the conveying pipe 3. When there are too many impurities on the filter screen 8, the filter screen 8 presses the connecting plate 54, and the spring 55 is compressed, which drives the slide rod 53 to slide in the positioning plate 52. Then, the limit plate 503 simultaneously drives the positioning block 502 to slide in the positioning groove 501, so as to drive the limit frame 504 to move. The slide plate 505 reminds the operator to avoid the filter screen 8 from being clogged due to too many impurities on the surface, which would reduce the working efficiency of the material conveying mechanism.

[0033] according to Figure 2 , Figure 3 , Figure 6 , Figure 7 Under the action of the drive motor 4, the transmission rod 41 drives the spiral blade 42 to rotate, thereby pushing the plastic into the discharge pipe 6. The servo motor 9 works synchronously, causing the first gear 91 to rotate and drive the meshing second gear 92 to rotate. Under the action of the connecting shaft, the control frame 10 rotates synchronously with the second gear 92. Then, the connecting rod 101 pulls the rotating plate 102, which in turn pulls the rotating seat 74 to drive the control plate 73 to move. The control plate 73 can slide along the direction of the connecting groove 201 through the connecting block 202, and the slider 23 slides along the direction of the slide rail 22 to achieve the purpose of reciprocating motion of the control plate 73. This realizes the quantitative feeding operation of the discharge pipe 6, avoiding the problem of excessive or insufficient raw materials during the operation of the injection molding machine, which leads to a decline in product quality.

[0034] In this device, the drive motor 4 and servo motor 9 are started after being connected to an external power source. The drive motor 4 and servo motor 9 are known and existing technologies on the market, and will not be described in detail here.

[0035] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
