Description

Technical Field

[0001] This utility model relates to the field of molding device technology, specifically to an integrated molding device for a multi-core plug housing assembly. Background Technology

[0002] Molding equipment is a key production device whose core function is to process raw materials (such as plastics, metals, ceramics, composite materials, etc.) into final or semi-finished products with predetermined shapes, sizes, and properties through specific processes (such as injection molding, die casting, extrusion, blow molding, compression molding, etc.). It typically consists of a frame, molds, heating / cooling systems, power systems, and control systems. It can precisely control process parameters such as temperature, pressure, and speed to ensure high precision, high consistency, and high quality of products. Molding equipment is widely used in many industries such as automotive, electronics, home appliances, medical, and packaging, and is a key link in modern manufacturing to achieve mass production and high efficiency.

[0003] The integrated molding device for multi-core plug housing assemblies is a highly specialized production equipment designed to simplify the complex process of assembling multi-core plugs, which typically consists of multiple independent components (such as upper and lower housings, fixing frames, and clips), into a single or a few consecutive molding steps. It usually employs injection molding technology, utilizing precisely designed composite molds to simultaneously or sequentially plasticize and inject molten plastic, accurately forming the internal and external structures of the plug housing. It may even mold internal fixing frames, positioning posts, or parts of the clip structure simultaneously. This integrated molding method significantly reduces subsequent assembly steps, the number of parts, and potential assembly errors. It not only greatly improves production efficiency and reduces manufacturing costs but also effectively enhances the structural strength, dimensional accuracy, and overall reliability of the final product. It is a crucial technological tool in the modern electronic connector manufacturing industry, driven by the pursuit of efficient and precise production.

[0004] However, existing integrated molding devices for multi-core plug housing assemblies, particularly those using traditional fixed connections, suffer from difficulty in precisely and stably controlling the mold-closing position of the upper and lower molds. This leads to deviations, resulting in inconsistent dimensions of the molded plug housings, affecting subsequent assembly and use. Furthermore, the upper mold may tilt or misalign when approaching the lower mold, causing deformation, cracking, or excessive internal stress in the molded product. Additionally, it can lead to difficulties in demolding, resulting in scratches or damage to the molded housing assembly and a reduced product yield. To address these issues, an integrated molding device for multi-core plug housing assemblies is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated molding device for a multi-core plug housing assembly, which solves the problems in the prior art of not being able to accurately and stably bring the molds closer or further apart and not being able to prevent the molds from shifting during displacement or demolding.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated molding device for a multi-core plug housing assembly, comprising a processing platform, a bearing frame fixedly connected to both ends of the top of the processing platform, a servo motor fixedly connected to one side of the bearing frame, the output end of the servo motor penetrating the bearing frame and fixedly connected to a worm gear, the worm gear being rotatably connected to the bearing frame, a transmission rod penetrating and rotatably connected to the inner wall of the bearing frame, a worm wheel penetrating and fixedly connected to the top of the outer ring of the transmission rod, the worm wheel being meshed with the worm gear, a double-groove synchronous pulley penetrating and fixedly connected to the bottom of the outer ring of the transmission rod, a lead screw penetrating and rotatably connected to both ends of the bearing frame, a single-groove synchronous pulley penetrating and fixedly connected to the top of each lead screw, a synchronous belt being provided between each double-groove synchronous pulley and the single-groove synchronous pulley, a nut pair threadedly connected to the outer ring of each lead screw, the nut pair penetrating and slidably connected to the bearing frame, an upper mold being provided between each nut pair, a connecting plate fixedly connected to one side of the top of the processing platform, a transmission assembly being provided on one side of the connecting plate, and an installation assembly being provided on the top of the upper mold.

[0007] By adopting the above technical solution, the linkage between the above structures allows the double-groove synchronous pulley and the single-groove synchronous pulley to be connected by a synchronous belt, ensuring that the lead screws at both ends rotate synchronously. This causes the nut pair to drive the upper mold to move closer to the lower mold evenly and synchronously, thereby avoiding mold displacement caused by uneven force on one side and improving molding efficiency and quality.

[0008] As a further description of the above technical solution: the transmission assembly includes a slider, which is slidably connected to one side of the connecting plate. A first push rod motor is fixedly connected to one side of the slider. The output end of the first push rod motor is fixedly connected to a pressure block through the slider, and the pressure block is slidably connected to the processing platform. A sealing plate is fixedly connected to the top center of the processing platform. A lower mold is slidably connected to the outer side of the sealing plate, and the lower mold is in contact with the pressure block. Bearing rods are fixedly connected to the bottom four sides of the lower mold, and the bearing rods are slidably connected to the processing platform. A fourth spring is sleeved on the outer ring of each bearing rod. Support rods are slidably connected to both ends of the top of the slider, and the support rods are fixedly connected to the connecting plate. A first spring is sleeved on the outer ring of each support rod.

[0009] By adopting the above technical solution, the linkage of the first spring and the fourth spring provides multi-level anti-eccentric load capability. Thus, the first spring provides buffering when the slider moves, reducing impact; the fourth spring provides a reverse force after the upper mold and lower mold of the bearing rod contact, helping to stabilize demolding, thereby effectively preventing the mold from being overloaded and damaged during the molding or demolding process, and extending the mold life.

[0010] As a further description of the above technical solution: the installation assembly includes a fixing plate, which is fixedly connected to the top of the upper mold. The fixing plate has evenly distributed sliding rods that pass through and are fixedly connected inside it. Each sliding rod has a third spring sleeved on one end of its outer ring.

[0011] By adopting the above technical solution, the installed fixed plate can connect to and support the required third spring, thereby driving the required slide plate to slide within the fixed plate.

[0012] As a further description of the above technical solution: the other end of the outer ring of each slide rod is slidably connected to a slide plate, and the slide plate is slidably connected to the fixed plate. The bottom of each slide plate is fixedly connected to a sealing block, and the sealing block is slidably connected to the fixed plate.

[0013] By adopting the above technical solution, the installed sliding plate can drive the sealing plate to slide on the fixed plate, and the sealing plate can ensure the sealing between the upper and lower molds during the processing.

[0014] As a further description of the above technical solution: a support plate is fixedly connected to one end of the support frame, and a second push rod motor is fixedly connected to the top of the support plate.

[0015] By adopting the above technical solution, the required second push rod motor can be connected and fixed through the installed support plate, thereby driving the pressure plate to slide up and down.

[0016] As a further description of the above technical solution: the output end of the second push rod motor passes through the bearing plate and is fixedly connected to a pressure plate, and both ends of the bottom of the pressure plate are fixedly connected to rotating rods.

[0017] By adopting the above technical solution, the required rotating rod can be connected and fixed by the installed pressure plate, thereby bearing the required second spring.

[0018] As a further description of the above technical solution: a second spring is sleeved on one end of the outer ring of each rotating rod, and a core is provided at the bottom of each rotating rod.

[0019] By adopting the above technical solution, the fixed block can slide on the rotating rod by installing the second spring.

[0020] As a further description of the above technical solution: the other end of the outer ring of the rotating rod is slidably connected to a fixing block, and the fixing block is slidably connected to the fixing plate, and the fixing block is in contact with the sealing block.

[0021] By adopting the above technical solution, the sealing block can be squeezed by the installed fixing block, thereby allowing the core to come into contact with the raw material in the mold.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0033] Reference Figure 1 and Figure 2 This utility model discloses an integrated molding device for a multi-core plug housing assembly, comprising a processing platform 1. The processing platform 1 can support the required equipment and drive the required motor. Support frames 2 are fixedly connected to both ends of the top of the processing platform 1, which can support and fix the required components and structures. A servo motor 3 is fixedly connected to one side of the support frame 2, allowing the worm gear 4 to rotate within the support frame 2. A transmission rod 5 is rotatably connected through the inner wall of the support frame 2, connecting and fixing the required worm gear 6 and double-groove synchronous pulley 7. Upper molds 17 are provided between the nut pairs 33, and the upper molds 17 and lower molds 18 can process the required raw materials into a specified shape. A connecting plate 11 is fixedly connected to one side of the top of the processing platform 1. Plate 11 can support and fix the required first push rod motor 15. A transmission component is provided on one side of the connecting plate 11. An installation component is provided on the top of the upper mold 17. The first push rod motor 15 is fixedly connected to one side of the slider 12. The installed first push rod motor 15 allows the pressure block 16 to slide on the processing platform 1. The lower mold 18 is slidably connected to the outside of the sealing plate 34, and the lower mold 18 contacts the pressure block 16. One end of the support frame 2 is fixedly connected to the support plate 19. The installed support plate 19 can fix and support the required second push rod motor 20. The top of the support plate 19 is fixedly connected to the second push rod motor 20. The installed second push rod motor 20 allows the pressure plate 21 to slide and move in a specified direction. The bottom of the rotating rod 22 is provided with a core 25. The core 25 can combine with the raw material in the mold to form a specified object shape.

[0034] Reference Figure 2The output end of the servo motor 3 passes through the support frame 2 and is fixedly connected to a worm gear 4, which is rotatably connected to the support frame 2. A worm wheel 6 passes through and is fixedly connected to the top of the outer ring of the transmission rod 5, and the worm wheel 6 meshes with the worm gear 4. A double-groove synchronous pulley 7 passes through and is fixedly connected to the bottom of the outer ring of the transmission rod 5. Both ends of the support frame 2 are rotatably connected to lead screws 9, and the tops of the lead screws 9 are fixedly connected to single-groove synchronous pulleys 10. A synchronous belt 8 is provided between the double-groove synchronous pulley 7 and the single-groove synchronous pulley 10. The outer ring of the lead screw 9 is threaded with a nut pair 33, which passes through and slides through the bearing frame 2. The rotation of the worm gear 4 causes the worm wheel 6 to drive the transmission rod 5 to rotate on the bearing frame 2, thereby driving the double-groove synchronous pulley 7 and the synchronous belt 8, which in turn causes the single-groove synchronous pulley 10 to rotate. This allows the lead screw 9 to rotate synchronously within the bearing frame 2, ensuring stability after the upper and lower dies 18 contact, preventing deviations caused by vibration or external forces during processing, and thus guaranteeing the accuracy of the forming dimensions. The transmission assembly includes... The slider 12 is slidably connected to one side of the connecting plate 11. The output end of the first push rod motor 15 passes through the slider 12 and is fixedly connected to the pressure block 16, which is slidably connected to the processing platform 1. A sealing plate 34 is fixedly connected to the top center of the processing platform 1. Bearing rods 31 are fixedly connected to the bottom of the lower mold 18 around its perimeter, and the bearing rods 31 are slidably connected to the processing platform 1. A fourth spring 32 is fitted around the outer ring of each bearing rod 31. Support rods 13 are slidably connected to both ends of the top of the slider 12, and the support rods 13 are fixedly connected to the connecting plate 11. A first spring 14 is fitted around the outer ring of each support rod 13. By sliding the pressure block 16, the pressure block 16 presses the lower mold 18, thereby causing the bearing rods 31 to slide on the processing platform 1, which in turn presses the fourth spring 32, causing the slider 12 to slide on the support rods 13, which in turn presses the first spring 14. This ensures safety during the processing and prevents equipment damage or personal injury caused by accidental movement or impact.

[0035] Reference Figure 1 , Figure 3 and Figure 4The mounting assembly includes a fixed plate 26, which is fixedly connected to the top of the upper mold 17. Evenly distributed sliding rods 27 are connected and fixedly inserted through the interior of the fixed plate 26. A third spring 28 is fitted onto one end of the outer ring of each sliding rod 27, and a sliding plate 29 is connected and slidably inserted through the other end of each sliding rod 27. The sliding plate 29 is slidably connected to the fixed plate 26. A sealing block 30 is fixedly connected to the bottom of each sliding plate 29, and the sealing block 30 is slidably connected to the fixed plate 26. The sliding of the sealing block 30 allows the sliding plate 29 to slide within the fixed plate 26, thereby sliding on the sliding rods 27 and compressing the third springs 28. This ensures good sealing of the upper and lower molds 18 after mold closing. The output end of the second push rod motor 20 passes through the bearing plate 19 and is fixedly connected to the pressure plate 21. Both ends of the bottom of the pressure plate 21 are fixedly connected to the rotating rod 22. One end of the outer ring of the rotating rod 22 is fitted with a second spring 23. The other end of the outer ring of the rotating rod 22 passes through and is slidably connected to the fixing block 24. The fixing block 24 is slidably connected to the fixing plate 26 and contacts the sealing block 30. By sliding the pressure plate 21, the fixing block 24 slides into the fixing plate 26, thereby allowing the rotating rod 22 to slide on the fixing block 24, thereby squeezing the second spring 23. This ensures the correct posture of the core 25 in the mold, thereby ensuring the uniformity and precision of the shell wrapping the core 25 after molding.

[0036] Working principle: The rotation of the worm 4, and the meshing connection between the worm 4 and the worm wheel 6, causes the worm wheel 6 to drive the transmission rod 5 to rotate on the bearing frame 2, thereby causing the double-groove synchronous pulley 7 to rotate on the bearing frame 2. Subsequently, through the transmission of the synchronous belt 8, the single-groove synchronous pulleys 10 at both ends rotate synchronously, causing the lead screws 9 at both ends to rotate synchronously on the bearing frame 2. This causes the nut pair 33 to drive the upper mold 17 to approach and contact the lower mold 18. Then, through the sliding of the pressure plate 21, the fixed block 24 slides into the fixed plate 26, thereby compressing the sealing block 30. This causes the sealing block 30 to slide within the fixed plate 26, which in turn causes the sliding plate 29 to slide within the fixed plate 26. The sliding plate 29 then slides on the sliding rod 27, thereby compressing the third spring 28. This causes the rotating rod 22 to slide on the fixed block 24, thereby compressing the second spring 23. This causes the core 25 to slide into the mold. Finally, through the transport mechanism set on the upper mold 17... The required raw material is poured into the mold through the tube to form the material. After processing, the pressure plate 21 is reset, and the nut assembly 33 moves the upper mold 17 away from the lower mold 18. Then, the pressure block 16 is slid, and the nut assembly 33 moves the upper mold 17 downward to contact the pressure block 16, causing the pressure block 16 to slide downward. This causes the two ends of the pressure block 16 to press against another spring, which in turn causes the slider 12 to slide on the connecting plate 11 and the support rod 13, thus pressing against the first spring 14. This causes the lower mold 18 to move downward, allowing the bearing rod 31 to slide on the processing platform 1, which in turn press against the fourth spring 32, thus demolding the material. The processed material is then removed. The rebound of the first spring 14 and the fourth spring 32 resets the slider 12, the pressure block 16, and the lower mold 18. The pressure block 16 is then reset by the first push rod motor 15, ready for the next processing.
