Description

Technical Field

[0001] This invention relates to the field of injection molding equipment technology, and more particularly to an injection molding production line. Background Technology

[0002] Injection molding is a common plastic processing technology. It involves injecting heated and molten plastic material into a mold, which then cools and solidifies to form the desired plastic product. This production method is commonly used for mass production of plastic products such as plastic parts, containers, and packaging. The plastic shells of switches and sockets are mostly injection molded using injection molding machines. Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment for making various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are divided into vertical, horizontal, and all-electric types. Injection molding machines heat the plastic and apply high pressure to the molten plastic, causing it to be injected and fill the mold cavity.

[0003] Most existing switch or socket injection molding equipment requires manual material collection during product unloading, and the products are then placed on a conveyor belt for transport to other stages. Some production equipment uses feeding devices such as hoppers to transport products onto the conveyor belt and then to other stages. However, when transporting products through hoppers, the products are prone to clogging inside the hopper, affecting the transport of products. This requires manual unclogging, which is inconvenient and incurs additional labor costs. Summary of the Invention

[0004] The purpose of this invention is to solve the shortcomings of existing technologies, such as products easily getting clogged in the hopper, affecting product conveying, requiring manual unblocking, and being inconvenient to use, and to propose an injection molding production line.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design an injection molding production line, including an injection molding machine and a conveyor belt. The lower end of the injection molding machine is fixedly equipped with a frame, one end of the conveyor belt is set inside the frame, the injection molding machine is equipped with a fixed frame, and the fixed frame is connected to the injection head through a cylinder mechanism. The conveyor belt is set below the discharge end of the injection molding machine.

[0007] The frame is equipped with a material collection hopper, which is located between the injection molding machine and the conveyor belt. The inlet of the material collection hopper corresponds to the outlet of the injection molding machine, and the outlet of the material collection hopper corresponds to the conveyor belt.

[0008] The hopper is equipped with an anti-blocking mechanism, and a mounting frame is fixedly mounted on the frame. The mounting frame is equipped with a motor for driving the anti-blocking mechanism.

[0009] Furthermore, the anti-clogging mechanism includes a guide section slidably disposed within the hopper, and the guide section is poweredly connected to the motor via a linkage mechanism.

[0010] Furthermore, the linkage mechanism includes an eccentric wheel fixedly mounted on the output shaft of the motor, a connecting rod rotatably connected to the eccentric wheel, and the connecting rod rotatably connected to the material guide.

[0011] Furthermore, a groove is provided on one side of the hopper to cooperate with the guide section, and the linkage mechanism includes a connecting part fixedly disposed on one side of the guide section to cooperate with the groove, and the connecting part is rotatably connected to the linkage.

[0012] Furthermore, the material guiding section is provided with a guide groove, and the inner wall of the collecting hopper is fixedly provided with a guide block that cooperates with the guide groove.

[0013] Furthermore, a first reset spring is provided between the guide block and the guide groove, and an exhaust hole is provided on the guide block or the material guide part.

[0014] Furthermore, the anti-clogging mechanism also includes a striking component disposed on one side of the hopper, the striking component being poweredly connected to the eccentric wheel.

[0015] Furthermore, the striking assembly includes a bracket fixedly connected to the hopper, a striking part slidably disposed on the bracket, and a guide part connected to the striking part cooperating with an eccentric wheel.

[0016] Furthermore, a second return spring is connected between the striking part and the bracket, and the guide part includes a connecting plate on which a guide rod is fixedly connected.

[0017] Furthermore, the eccentric wheel has a groove that mates with the guide rod, and the eccentric wheel also has a guide groove that mates with the guide rod, with the guide rod being movably inserted into the guide groove.

[0018] The injection molding production line proposed in this invention has the following advantages:

[0019] In this invention, during production, the injection-molded workpieces are transferred to the conveyor belt via a hopper. A motor drives the guide part to move up and down to prevent the injection-molded workpieces from getting stuck in the hopper, making the workpieces unload more smoothly. A striking component is set up to strike the hopper, thereby causing the internal workpieces to vibrate and avoid blockage. No additional personnel are needed to clear the blockage, reducing labor costs.

[0020] Secondly, in this invention, by setting guide grooves and guide blocks to restrict the movement trajectory of the guide part, it is prevented from tilting and squeezing the workpiece. Furthermore, the guide part is moved upward and reset by the first spring, thereby enabling the guide part to move back and forth and clear the hopper. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Reference Figure 1-6 An injection molding production line includes an injection molding machine 1 and a conveyor belt 2. A frame 3 is fixedly installed at the lower end of the injection molding machine 1. One end of the conveyor belt 2 is installed inside the frame 3. A fixed frame 11 is provided on the injection molding machine 1. An injection head 13 is connected to the fixed frame 11 through a cylinder mechanism 12. The conveyor belt 2 is located below the discharge end of the injection molding machine 1.

[0030] A material collection hopper 4 is provided on the frame 3. The material collection hopper 4 is located between the injection molding machine 1 and the conveyor belt 2. The inlet of the material collection hopper 4 corresponds to the outlet of the injection molding machine 1, and the outlet of the material collection hopper 4 corresponds to the conveyor belt 2.

[0031] An anti-blocking mechanism 5 is provided on the hopper 4, and a mounting frame 6 is fixedly provided on the frame 3. A motor 7 for driving the anti-blocking mechanism 5 is provided on the mounting frame 6.

[0032] In this invention, the workpieces injection-molded by the injection molding machine 1 are transferred to the conveyor belt 2 through the hopper 4. The anti-blocking mechanism 5 is set to prevent the injection-molded workpieces from blocking in the hopper 4, making the workpiece discharge smoother. In this embodiment, the cylinder mechanism 12 includes a cylinder fixedly mounted on the fixed frame 11. The output shaft of the cylinder is fixedly mounted on the connecting frame. The injection head is mounted on the connecting frame to perform injection molding on the mold composed of the moving mold and the fixed mold. After the workpiece is injection-molded, the injection head is controlled by the cylinder to move down and push the workpiece out to avoid adhesion.

[0033] Furthermore, in this embodiment, the anti-clogging mechanism 5 includes a guide part 51 that is slidably disposed in the hopper 4. The guide part 51 is poweredly connected to the motor 7 through a linkage mechanism. The motor 7 controls the guide part 51 to move up and down through the linkage mechanism, thereby clearing the hopper 4.

[0034] In this embodiment, the linkage mechanism includes an eccentric wheel 52 fixedly mounted on the output shaft of the motor 7. A connecting rod 53 is rotatably connected to the eccentric wheel 52. The connecting rod 53 is rotatably connected to the material guide part 51. When the motor 7 drives the eccentric wheel 52 to rotate, the eccentric wheel 52 will pull or drag the connecting rod 53 to move, thereby driving the material guide part 51 to move up and down to clear the hopper 4.

[0035] Furthermore, in this embodiment, a groove 54 is provided on one side of the hopper 4 to cooperate with the guide part 51. The linkage mechanism includes a connecting part 55 fixedly disposed on one side of the guide part 51 and cooperating with the groove 54. The connecting part 55 is rotatably connected to the connecting rod 53. When the connecting rod 53 moves, it will drive the connecting part 55 and the guide part 51 to move up and down. And because it is a rotatable connection structure, when the angle of the connecting rod 53 changes, it will not affect the linear movement of the connecting part 55 and the guide part 51.

[0036] In this embodiment, a guide groove 56 is provided on the material guiding part 51, and a guide block 57 that cooperates with the guide groove 56 is fixedly provided on the inner wall of the material collecting hopper 4. By cooperating with the guide groove 56 on the material guiding part 51, the movement trajectory of the material guiding part 51 is restricted, so that it moves up and down in a straight line.

[0037] It should be noted that in this embodiment, a first reset spring 58 is provided between the guide block 57 and the guide groove 56, and an exhaust hole is provided on the guide block 57 or the guide part 51. The guide part 51 is moved upward and reset by the first reset spring 58, so that the guide part 51 can move back and forth to clear the hopper 4. The exhaust hole is provided to prevent the air inside the guide groove 56 from affecting the operation of the guide part 51.

[0038] In this embodiment, the anti-blocking mechanism 5 also includes a striking component 8 disposed on one side of the hopper 4. The striking component 8 is poweredly connected to the eccentric wheel 52. The striking component 8 strikes the hopper 4, thereby causing the hopper 4 and the workpiece inside it to vibrate, thereby loosening and moving the workpieces downward to avoid blockage.

[0039] Furthermore, in this embodiment, the striking component 8 includes a bracket 81 fixedly connected to the hopper 4. A striking part 82 is slidably disposed on the bracket 81. The striking part 82 is connected to a guide part 83 that cooperates with the eccentric wheel 52. The guide part 83 drives the striking part 82 to move and strike the outer wall of the hopper 4.

[0040] In this embodiment, a second reset spring is connected between the striking part 82 and the bracket 81. The guide part 83 includes a connecting plate 831, and a guide rod 832 is fixedly connected to the connecting plate 831. The second reset spring generates elastic deformation and stores energy, thereby controlling the striking part 82 to strike the hopper 4 during reset.

[0041] More specifically, in this embodiment, the eccentric wheel 52 is provided with a groove 84 that cooperates with the guide rod 832. When the eccentric wheel 52 rotates, the guide part 83 drives the striking part 82 to move, and the second return spring undergoes elastic deformation to store energy. When the guide part 83 is in the groove 84, it loses the support of the support, and the second return spring deforms and resets, driving the striking part 82 to contact the hopper 4 and strike it. The eccentric wheel 52 is also provided with a guide groove 85 that cooperates with the guide rod 832. The guide rod 832 is movably inserted into the guide groove 85. By setting the guide groove 85, the guide rod 832 is guided to prevent it from separating from the eccentric wheel 52.

[0042] Working method: During operation, the workpiece is injection molded by the injection molding machine 1, and the eccentric wheel 52 is rotated by the motor 7, which pulls or drags the connecting rod 53 to move, thereby driving the guide part 51 to move up and down to clear the hopper 4. The guide part 51 is moved upward and reset by the first return spring 58, so that the guide part 51 can move back and forth to clear the hopper 4. When the eccentric wheel 52 rotates, the guide part 83 drives the striking part 82 to move. The second return spring undergoes elastic deformation and stores energy. When the guide part 83 is in the groove 84, it loses the support and the second return spring deforms and resets, driving the striking part 82 to contact the hopper 4 and strike it, thereby loosening the workpiece and moving it downward to avoid blockage.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
