Description

Technical Field

[0001] The present invention belongs to the technical field of plug accessory manufacturing, and in particular relates to an integrated injection molding device for a plug inner frame. Background Art

[0002] A power plug is an electrical interface device used to connect an electrical appliance to a power source. It completes circuit conduction by inserting into a socket to provide power transmission for the device. Conventionally, a power plug includes a plug inner frame. As shown in Figure 1 , the plug inner frame 9 is composed of a base 91 and pins 92. One end of the pins 92 penetrates through the base 91 and is used to connect to an external power socket, and the other end of the pins 92 is used to connect to a wire.

[0003] The base in the plug inner frame is generally made of plastic, and its production requires the use of injection molding equipment. Conventionally, as disclosed in a plug integrated injection molding device with the application number CN2022102325568, it includes an injection molding mechanism, a feeding mechanism, and a discharging mechanism. The feeding mechanism includes a vibrating plate, a conveying member connected to the outlet of the vibrating plate at one end, and a material conveying assembly connected to the end of the conveying member away from the vibrating plate. The discharging mechanism includes a discharging table, a discharging plate, a horizontal moving cylinder, a vertical moving cylinder, a thumb cylinder, a rotating assembly, and a receiving hopper. In this technical solution, before injection molding the plug inner frame, the pins are first conveyed to the injection molding mechanism through the feeding mechanism. Specifically, when the material conveying plate moves to directly above the fixed mold, the discharging plate moves above the material conveying plate through the horizontal moving cylinder. At this time, multiple ejector pins correspond to the holes in multiple material containing cavities one by one. Then, the piston rod of the vertical moving cylinder extends, and the vertical moving cylinder drives the horizontal moving cylinder to move downward, so that the ejector pins are inserted into the holes in the material containing cavities, thereby ejecting the pins in the holes of the material containing cavities. After the plug inner frame is injection molded, the ejector rods in the fixed mold push several plug inner frames, the sprue, and the runner upward, clamp the runner through the thumb cylinder, and finally transfer several plug inner frames, the sprue, and the runner to the receiving hopper.

[0004] In the above technical solution, the ejector pins and the thumb cylinder are integrated on two sides of the discharging plate and are flipped through the rotating assembly, so as to use the ejector pins to push the pins or use the thumb cylinder to clamp the runner. Although the two functions are integrated, further, the rotating assembly includes a gear, a rack, and a hydraulic cylinder. The gear is connected to the discharging plate and meshes with the rack, using the gear and rack as the connection point between the discharging plate and the horizontal moving cylinder, resulting in insufficient stability. Moreover, the discharging plate is integrated with structures such as ejector pins and thumb cylinders, causing a large load on the gear and rack, prone to wear. After wear, the rotation accuracy will be reduced, so frequent maintenance is required, and the maintenance cost is relatively high. Summary of the Invention

[0016] Compared with the prior art, the advantages of the present invention are: 1. This technical solution uses a driving mechanism to drive a pushing member forward into the injection molding mechanism to push the pins, or to move a fixture forward into the injection molding mechanism to grasp the handle. Compared with the conventional flipping structure, the pushing and pulling structure has better stability, is not prone to wear, helps to ensure the accuracy during the long-term use of the equipment, does not require frequent maintenance, and helps to reduce the maintenance cost. 2. In this technical solution, the pushing member and the fixture are separately arranged. Compared with integrating the pushing member and the fixture onto the blanking plate, it can avoid vibration or deformation caused by concentrated load in the integrated design and ensure high-precision movement. 3. When the elastic chuck continuously holds the handle and moves backward with the finished product, the first mounting plate moves forward. The first mounting plate will contact the handle and push the handle forward out of the elastic chuck, releasing the restriction on the handle, and the finished product will naturally fall into the receiving basket. The design of this mechanism does not require a motor (such as a thumb cylinder) to control the jaw assembly to grasp or release the handle, reducing the control nodes, helping to reduce the hardware cost, and having better reliability, which is suitable for large-scale continuous production operation scenarios.

[0019] The present invention will be further described in detail below in conjunction with the embodiments in the drawings.

[0020] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is 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 a limitation of the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0021] Embodiment 1: As Figures 1 to 4 shown, an integrated injection molding device for the inner frame of a plug includes a feeding mechanism (not shown in the figure), an injection molding mechanism 1, a mounting seat 2, a driving mechanism 3, a pusher 4, a fixture 5, and a lifting cylinder 6. The feeding mechanism includes a vibrating disk, a material transporting disk, and a linear module. The pins in the vibrating disk are transferred to the material transporting disk through a transmission track, and the linear module is used to transfer the material transporting disk into the injection molding mechanism 1 or the output end of the transmission track. The driving mechanism 3 is arranged on the mounting seat 2. The driving mechanism 3 is used to drive the pusher 4 to move forward into the injection molding mechanism 1 to push the pins, or to move the fixture 5 forward into the injection molding mechanism 1 to grab the handle. The lifting cylinder 6 is used to control the up and down movement of the mounting seat 2. Conventionally, a mounting frame 7 and a receiving basket 8 are arranged beside the injection molding mechanism 1. The lifting cylinder 6 is arranged on the top plate 71 of the mounting frame 7. The telescopic shaft of the lifting cylinder 6 extends downward and is connected to the mounting seat 2 through an adapter plate. The receiving basket 8 is located between the mounting frame 7 and the injection molding mechanism 1.

[0022] In this embodiment, the injection molding mechanism 1 includes a stationary mold 11 and a movable mold 12 located above the stationary mold 11. The stationary mold 11 and the movable mold 12 cooperate to form a plurality of cavities 13 that are consistent with the plug inner frame 9. A runner 14 is provided between the plurality of cavities 13. An injection port 15 communicating with the runner is provided on the movable mold 12. A plurality of through holes communicating with the runner 14 are provided in the stationary mold 11, and ejector pins 16 capable of moving up and down are provided in the through holes. After the movable mold 12 and the stationary mold 11 are clamped, plastic is injected into the runner 14 and the cavities 13 from the injection port 15. After the plastic is cooled and solidified, the movable mold 12 and the stationary mold 11 are separated to obtain a finished product as shown in Figure 4 The finished product shown contains a plurality of plug inner frames 9, a sprue and a runner connecting the plurality of plug inner frames 9. Then, the finished product is pushed upward by the ejector pins 16 so that the sprue can be clamped by the fixture 5 and the finished product can be transferred. The ejector pins 16 and the through holes are generally provided at the nodes of the runner 14. It should be noted that the injection molding mechanism 1 is an existing technology in the art and is not an improvement point of this technical solution. Its specific structure and usage method will not be described in detail here.

[0023] In this embodiment, a plurality of material receiving cavities for placing pins are provided on the material transporting tray. The material receiving cavities penetrate the upper surface of the material transporting tray. When the material transporting tray is transferred into the injection molding mechanism 1, the material transporting tray is located on the stationary mold 11, and the plurality of material receiving cavities are located above the plurality of cavities 13. At this time, the driving mechanism 3 drives the pushing member 4 to move forward into the injection molding mechanism 1. The pushing member 4 is located above the material transporting tray. In cooperation with the lifting cylinder 6, the mounting seat 2, the driving mechanism 3 and the pushing member 4 are controlled to move downward synchronously. The pushing member 4 ejects the pins in the material receiving cavities, and the pins are transferred into the cavities 13. It should be noted that the vibrating disk, the material transporting tray and the linear module are existing technologies in the art and are not improvement points of this technical solution. For their specific structures and usage methods, reference can be made to the description in a plug integrated injection molding device with the application number CN2022102325568, which will not be elaborated here.

[0024] In order to facilitate the accurate falling of the finished product into the material receiving basket 8, an inclined blanking track is provided on the material receiving basket 8. The blanking track is placed on one side of the injection molding mechanism 1 so that the finished product can enter the material receiving basket 8 along the blanking track.

[0025] This technical solution separates the pushing member 4 and the fixture 5. The driving mechanism 3 drives the pushing member 4 to move forward into the injection molding mechanism 1 to push the pins, or drives the fixture 5 to move forward into the injection molding mechanism 1 to grab the sprue. Compared with the conventional flipping structure, the pushing and pulling structure has better stability, is not prone to wear, helps to ensure the accuracy during the long-term use of the equipment, does not require frequent maintenance, and helps to reduce the maintenance cost.

[0026] Embodiment 2: As shown in Figure 2 、 Figure 5 And Figure 6As shown, the rest is the same as in the first embodiment, except that the driving mechanism 3 includes a driving motor 31, a first gear 32, a first strip plate 33 and a second strip plate 34. The driving motor 31 is arranged on the mounting base 2, and the output shaft of the driving motor 31 is connected to the first gear 32. The first strip plate 33 and the second strip plate 34 are distributed on the left and right sides of the first gear 32. Tooth portions for meshing with the first gear 32 are respectively arranged on the side surface of the first strip plate 33 and the side surface of the second strip plate 34. The height where the first strip plate 33 is located is lower than the height where the second strip plate 34 is located. The pushing member 4 is arranged at the front end of the first strip plate 33, and the fixture 5 is arranged at the front end of the second strip plate 34. When the driving motor 31 drives the first gear 32 to rotate, the first strip plate 33 and the second strip plate 34 move in opposite directions, so that the pushing member 4 moves forward into the injection molding mechanism 1, or the fixture 5 moves forward into the injection molding mechanism 1. It should be noted that the height where the first strip plate 33 is located is lower than the height where the second strip plate 34 is located, which can ensure that the pushing member 4 and the fixture 5 do not interfere during the forward and backward movement.

[0027] In this structure, when the driving motor 31 drives the first gear 32 to rotate, it will simultaneously control the first strip plate 33 and the second strip plate 34 to move in opposite directions, so that the pushing member 4 moves forward into the injection molding mechanism 1, or the fixture 5 moves forward into the injection molding mechanism 1. This not only helps to accurately coordinate the pushing member 4 and the fixture 5, but also uses a single motor to drive two components to move, which helps to reduce the complexity of the control system.

[0028] Embodiment Three: As Figures 5 to 8 shown, the rest is the same as in the second embodiment, except that the mounting base 2 includes two side plates 21 distributed left and right, and the two side plates 21 are connected by a cross beam 22. A sliding groove 211 is arranged on one side of the side plate 21 facing the cross beam 22, and the sliding groove 211 penetrates through the front and rear end faces of the side plate 21. The heights of the two sliding grooves 211 are different. The sliding groove 211 at the lower position is in front and rear sliding fit with the first strip plate 33, and the sliding groove 211 at the higher position is in front and rear sliding fit with the second strip plate 34. A first through hole 221 is arranged on the cross beam 22, and the output shaft of the driving motor 31 passes through the first through hole 221 and is connected to the first gear 32. Among them, the sliding groove 211 is in front and rear sliding fit with the first strip plate 33 and the second strip plate 34, which helps to ensure the stability of the linear movement of the first strip plate 33 and the second strip plate 34, and the reliability is better.

[0029] In this embodiment, the pushing member 4 includes a first mounting plate 41. The rear end of the first mounting plate 41 is fixedly connected to the front end of the first strip plate 33, and a plurality of push rods 42 for pushing the pins are fixedly arranged on the lower end surface of the first mounting plate 41.

[0030] In this embodiment, the clamp 5 includes a second mounting plate 51 and a clamping jaw assembly 52 disposed on an upper end surface of the second mounting plate 51 , and a clamping end of the clamping jaw assembly 52 extends to the front of the second mounting plate 51 .

[0031] Embodiment 4: Figures 8 to 10 As shown, the rest of the parts are the same as those of the third embodiment, except that the clamping jaw assembly 52 includes an elastic clamp 521, a third strip plate 522, two second gears 523, two guide rails 524 and two guide rods 525, the elastic clamp 521 is fixedly arranged at the front end of the third strip plate 522, the left and right sides of the third strip plate 522 are respectively provided with teeth, the two second gears 523 are distributed on the left and right sides of the third strip plate 522 and are respectively meshed with the teeth of the third strip plate 522, and the two guide rails 524 are respectively provided with teeth of the third strip plate 522. The guide rails 524 are distributed on the left and right sides of the third strip plate 522. The guide rails 524 are oriented from the back to the front and tilted toward the middle. The two guide rods 525 correspond to the two guide rails 524 one by one and are slidably connected. The middle side of the guide rod 525 is provided with a tooth portion meshing with the second gear 523. The front end of the guide rod 525 is bent backward and fixed with a pressure plate 526. The pressure plate 526 is located obliquely in front of the elastic clamp 521. The rear end of the third strip plate 522 is connected to the side plate 21 (see Figure 7 ), when the clamp 5 moves forward into the injection molding mechanism 1, the third strip plate 522 moves forward, the elastic clamp 521 and the two pressing plates 526 gather toward the center so that the material handle is grasped by the elastic clamp 521, and when the clamp 5 moves backward, the third strip plate 522 moves backward, the elastic clamp 521 and the two pressing plates 526 disperse, and the elastic clamp 521 continues to clamp the material handle. Among them, a guide rod 525, the third strip plate 522, and another guide rod 525 are distributed in sequence from top to bottom, and the middle part of the third strip plate 522 and the middle part of the guide rod 525 are cross-distributed.

[0032] Furthermore, the elastic clamp 521 includes an elastic arc plate 5211, the opening of the arc plate 5211 faces forward, and the opening angle is less than 180 degrees, and guide plates 5212 extending from the back to the front and outward are respectively provided at both ends of the arc plate 5211. In the process of the elastic clamp 521 and the two pressing plates 526 being retracted toward the center, the material handle first contacts the guide surface of the guide plate 5212, and then the opening of the arc plate 5211 is stretched open to enter the arc plate 5211, and the opening of the arc plate 5211 is retracted, and finally the inner wall of the arc plate 5211 is closely attached to the material handle to continuously clamp the material handle.

[0033] When the elastic clamp 521 continues to clamp the material handle and moves backward with the finished product, the first mounting plate 41 (see Figure 6 ) moves forward, the first mounting plate 41 will contact the material handle and push the material handle forward to the elastic clamp 521, so that the material handle is free from the restriction, and the finished product naturally falls into the receiving basket 8 (see Figure 2) inside. The design of this mechanism does not require a motor (such as a thumb cylinder) to control the gripper assembly 52 to grasp or release the handle, reducing the control nodes, helping to reduce the hardware cost, and having better reliability, which is suitable for the mass continuous production operation scenario.

[0034] Further, in order to discharge the finished product at a position farther from the injection molding mechanism 1 (see Figure 2 ), a notch 411 is formed by the front end of the first mounting plate 41 recessing backward. The notch 411 penetrates the upper and lower end faces of the first mounting plate 41, and the width of the notch 411 is greater than the diameter of the handle, so that the handle can enter the notch 411 and finally contact the inner bottom surface of the notch 411 before discharging.

[0035] Embodiment Five: As Figure 11 and Figure 12 shown, the rest is the same as that in Embodiment Four. The difference lies in that the linkage mechanism 53 includes a connecting rod 531, a third gear 532, and a rack 533. The front end of the connecting rod 531 is fixedly connected to the rear end of the third strip plate 522. A tooth portion is provided on the side surface of the connecting rod 531. The third gear 532 is rotatably arranged on the second strip plate 34. The rack 533 is fixedly arranged on the side surface of the side plate 21. The tooth portion on the connecting rod 531 and the rack 533 are respectively engaged with the third gear 532. When the second strip plate 34 moves forward, the third gear 532 meshes with the rack 533, the third gear 532 rotates and drives the connecting rod 531 to move forward, so that the third strip plate 522 moves forward; when the second strip plate 34 moves backward, the third gear 532 rotates and finally disengages from the rack 533. During the rotation of the third gear 532, the connecting rod 531 is driven to move backward, so that the third strip plate 522 moves backward. The opening and closing of the gripper assembly 52 are completely triggered by the forward and backward movement of the second strip plate 34, eliminating the need for additional sensors or electronic control modules and reducing the system complexity.

[0036] In this embodiment, a strip hole 5311 extending in the front-rear direction is provided on the connecting rod 531, and a positioning post 341 is provided on the second strip plate 34. The positioning post 341 extends into the strip hole 5311, and the cooperation between the positioning post 341 and the strip hole 5311 plays a positioning role to prevent the connecting rod 531 from shifting.

[0037] The brief working process of the plug inner frame integrated injection molding equipment disclosed in the above embodiments is as follows: S1. The pins in the vibrating bowl are transferred to the material transporting tray through the transmission track, and the linear module transfers the material transporting tray into the injection molding mechanism and positions it above the fixed mold; S2. The driving mechanism drives the pushing member to move forward into the injection molding mechanism and position it directly above the material transporting tray, and the fixture moves backward and is located outside the injection molding mechanism; S3, the lifting cylinder controls the mounting seat to move downward, and the push piece transfers the pins in the material storage cavity of the material transport tray to the cavity of the fixed mold; S4, the lifting cylinder controls the mounting seat to move upward, and the push piece is separated from the transport tray; S5, the driving mechanism drives the pusher to move backward and leave the injection molding mechanism, the fixture moves forward but does not enter the injection molding mechanism, the linear module transfers the material transport tray to the output end of the transmission track, and the material transport tray leaves the injection molding mechanism; S6, the movable mold moves down and closes with the fixed mold to perform injection molding; S7, after the injection molding is completed, the movable mold moves upward and separates from the fixed mold, and the ejector in the fixed mold ejects the finished product obtained by injection molding upward; S8, the driving mechanism drives the clamp to move forward to the injection molding mechanism to clamp the material handle, and the pusher moves backward and is located outside the injection molding mechanism; S9, the driving mechanism drives the fixture to move backward, the fixture takes the finished product away from the injection molding mechanism, and the ejector moves forward; S10, the pusher moves forward to contact the material handle and pushes the material handle forward out of the clamp, the material handle is freed from the restriction, and the finished product naturally falls into the receiving basket.

[0038] Among them, step S1 is a conventional technical means in this field.

[0039] In step S8, when the driving mechanism drives the clamp to move forward to the injection molding mechanism, the third gear engages with the rack, the third gear rotates and drives the connecting rod to move forward, so that the third strip plate moves forward, the third strip plate drives the two second gears to rotate, the guide rod moves obliquely rearward, and the elastic chuck and the two pressure plates converge toward the center so that the material handle is grasped by the elastic chuck.

[0040] In step S9, when the driving mechanism drives the clamp to move backward, the third gear rotates in the opposite direction and finally disengages from the rack. During the rotation of the third gear, the connecting rod is driven to move backward, so that the third strip plate moves backward. The third strip plate drives the two second gears to rotate in the opposite direction, and the guide rod moves obliquely forward, and the elastic clamp and the two pressure plates are dispersed.

It is obvious that the implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
