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 being inserted 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 pin 92 passes through the base 91 and is used to connect to an external power socket, and the other end of the pin 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, such as a plug integrated injection molding device disclosed in the application number CN2022102325568, which 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 of the plug inner frame, the pins are first conveyed to the injection molding mechanism by 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, a plurality of ejector pins correspond to the holes in a plurality of material receiving 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 receiving cavities, thereby ejecting the pins in the holes of the material receiving cavities. After the plug inner frame is injection molded, the ejector rods in the fixed mold push a plurality of plug inner frames, the sprue, and the runner upward, clamp the runner by the thumb cylinder, and finally transfer a plurality of 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, and the gear and rack are used 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, resulting in a large load on the gear and rack, which is 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:

[0017] 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.

[0018] 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.

[0019] 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 good reliability, being suitable for large-scale continuous production operation scenarios.

[0033] The present invention will be further described in detail below with reference to the embodiments in the accompanying drawings.

[0034] 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, and 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 should not be construed as a limitation to the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0035] Embodiment 1: As Figures 1 to 4As shown in the figure, an integrated injection molding device for a plug inner frame includes a feeding mechanism (not shown in the figure), an injection molding mechanism 1, a mounting base 2, a driving mechanism 3, a pushing member 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. 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 base 2. The driving mechanism 3 is used to drive the pushing member 4 to move forward into the injection molding mechanism 1 to push the pins, or to drive the fixture 5 to move forward into the injection molding mechanism 1 to grab the material handle. The lifting cylinder 6 is used to control the up and down movement of the mounting base 2. Conventionally, an installation frame 7 and a material receiving basket 8 are arranged beside the injection molding mechanism 1. The lifting cylinder 6 is arranged on the top plate 71 of the installation frame 7. The telescopic shaft of the lifting cylinder 6 extends downward and is connected to the mounting base 2 through an adapter plate. The material receiving basket 8 is located between the installation frame 7 and the injection molding mechanism 1.

[0036] In this embodiment, the injection molding mechanism 1 includes a fixed mold 11 and a movable mold 12 located above the fixed mold 11. The fixed 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 arranged between the plurality of cavities 13. An injection port 15 communicating with the runner is arranged on the movable mold 12. A plurality of through holes communicating with the runner 14 are arranged in the fixed mold 11. A ejector rod 16 capable of moving up and down is arranged in the through holes. After the movable mold 12 and the fixed mold 11 are closed, plastic is injected into the runner 14 and the cavities 13 from the injection port 15. After the plastic cools and solidifies, the movable mold 12 and the fixed mold 11 are separated to obtain Figure 4 the finished products as shown in the figure, including a plurality of plug inner frames 9, a material head and a material handle connecting the plurality of plug inner frames 9. Then, the finished products are ejected upward by the ejector rod 16 so that the fixture 5 can clamp the material handle and transfer the finished products. The ejector rod 16 and the through holes are generally arranged at the nodes of the runner 14. It should be noted that the injection molding mechanism 1 is an existing technology in the field and is not an improvement point of this technical solution. Its specific structure and usage method are not described in detail here.

[0037] In this embodiment, a plurality of material receiving cavities for placing pins are arranged on the material transporting disk. The material receiving cavities penetrate the upper surface of the material transporting disk. When the material transporting disk is transferred into the injection molding mechanism 1, the material transporting disk is located on the fixed 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 disk. Cooperating with the lifting cylinder 6 to control the synchronous downward movement of the mounting base 2, the driving mechanism 3, and the pushing member 4, 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 disk, and the linear module are existing technologies in the field and are not improvement points of this technical solution. Their specific structures and usage methods refer to the description in an integrated injection molding device for a plug with the application number CN2022102325568, and will not be elaborated here.

[0038] In order to facilitate the accurate placement of the finished product into the receiving basket 8, an inclined blanking track is provided on the receiving basket 8, and the blanking track is placed on one side of the injection molding mechanism 1 so that the finished product can enter the receiving basket 8 along the blanking track.

[0039] In this technical solution, the pusher 4 and the fixture 5 are separately arranged. The driving mechanism 3 drives the pusher 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 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.

[0040] Embodiment 2: As Figure 2 、 Figure 5 and Figure 6 shown, the rest is the same as that of Embodiment 1. The difference lies in 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 seat 2, 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 respectively, the sides of the first strip plate 33 and the second strip plate 34 are respectively provided with tooth parts for meshing with the first gear 32, the height where the first strip plate 33 is located is lower than the height where the second strip plate 34 is located, the pusher 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 pusher 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 pusher 4 and the fixture 5 will not interfere during the forward and backward movement.

[0041] 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 pusher 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 pusher 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.

[0042] Embodiment 3: As Figures 5 to 8As 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 provided on the side of the side plate 21 facing the cross beam 22, and the sliding groove 211 penetrates 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 slidably matched with the first strip plate 33 in the front and rear directions, and the sliding groove 211 at the higher position is slidably matched with the second strip plate 34 in the front and rear directions. A first through hole 221 is provided 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 slidably matched with the first strip plate 33 and the second strip plate 34 in the front and rear directions, which helps to ensure the stability of the linear motion of the first strip plate 33 and the second strip plate 34, and the reliability is relatively good.

[0043] 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 provided on the lower end surface of the first mounting plate 41.

[0044] In this embodiment, the fixture 5 includes a second mounting plate 51 and a jaw assembly 52 provided on the upper end surface of the second mounting plate 51. The clamping end of the jaw assembly 52 extends to the front of the second mounting plate 51.

[0045] Embodiment Four: As Figures 8 to 10 shown, the rest is the same as in the third embodiment, except that the jaw assembly 52 includes an elastic chuck 521, a third strip plate 522, two second gears 523, two guide rails 524 and two guide rods 525. The elastic chuck 521 is fixedly provided at the front end of the third strip plate 522. Tooth portions are respectively provided on the left and right sides of the third strip plate 522. 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 tooth portions of the third strip plate 522. The two guide rails 524 are distributed on the left and right sides of the third strip plate 522. The orientation of the guide rail 524 is from the rear to the front and inclined towards the middle. The two guide rods 525 are in one-to-one correspondence with the two guide rails 524 and are slidably connected. A tooth portion meshed with the second gear 523 is provided on the middle side surface of the guide rod 525. The front end of the guide rod 525 is bent backward and fixedly provided with a pressing plate 526. The pressing plate 526 is located obliquely in front of the elastic chuck 521. The rear end of the third strip plate 522 is connected to the side plate 21 through a linkage mechanism 53 (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.

[0046] 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.

[0047] 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 ). The design of this mechanism does not require the use of a motor (such as a thumb cylinder) to control the gripper assembly 52 to grasp or release the material handle, which reduces the control nodes, helps to reduce hardware costs, has good reliability, and is suitable for large-scale continuous production operations.

[0048] Further, in order to make the finished product at a distance of 1 (see Figure 2 ) is used for cutting material at a position farther away, the front end of the first mounting plate 41 is recessed backward to form a notch 411, the notch 411 runs through the upper and lower end surfaces of the first mounting plate 41, and the width of the notch 411 is greater than the diameter of the material handle, so that the material handle can enter the notch 411 and finally contact the inner bottom surface of the notch 411 for cutting material.

[0049] Embodiment 5: Figure 11 and Figure 12As shown, the rest is the same as in the fourth embodiment, except 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 provided on the second strip plate 34. The rack 533 is fixedly provided 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, and 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 jaw 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.

[0050] In this embodiment, a strip hole 5311 extending in the front-rear direction is provided on the connecting rod 531. A positioning post 341 is provided on the second strip plate 34. The positioning post 341 extends into the strip hole 5311. The cooperation between the positioning post 341 and the strip hole 5311 plays a positioning role to prevent the connecting rod 531 from shifting.

[0051] The brief working process of the plug inner frame integrated injection molding equipment disclosed in the above embodiments is as follows:

[0057] S6. The moving mold moves downward to close with the fixed mold for injection molding;

[0058] 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;

[0060] 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;

[0061] 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.

[0062] Among them, step S1 is a conventional technical means in this field.

[0063] 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.

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.
