Description

Technical Field

[0001] The invention relates to the technical field of data line outer mold forming, in particular to a forming mold for processing a data line outer mold. Background Art

[0002] In today's digital age, electronic devices are widely used. Various data cables are key accessories for connecting different electronic devices and realizing data transmission and charging functions, which has led to a sharp expansion in production scale. The outer mold of the data cable is an important component to protect the internal cables and ensure that the data cable has good physical properties and appearance quality. With the quality requirements of consumers for electronic devices, higher standards are put forward for the fineness, durability and appearance consistency of the outer mold. For example, the outer mold of the data cable adapted for high-end electronic devices must not only have excellent wear resistance and anti-bending properties, but also maintain a smooth, flawless appearance and uniform color to match the high-end positioning of the product.

[0003] At present, some molds for processing data cable outer molds mostly rely on the operator's experience in terms of the quantitative injection material. They manually adjust the feed valve or use simple quantitative containers for rough estimation, and cannot accurately control the amount of material entering the mold. On the one hand, it is easy to cause a large amount of raw material waste and increase production costs; on the other hand, due to inaccurate material dosage, the data cable outer mold product after molding has frequent defects such as dimensional deviation and material shortage, and the product qualification rate is low, which seriously restricts production efficiency. It leads to serious waste of raw materials and unstable product quality. Once the product has quality defects due to material problems, it will not only cost extra cost for rework or scrapping, but also affect the overall performance of the data cable, trigger customer complaints, and have a negative impact on the company's reputation. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a molding die for processing a data cable outer mold, which solves the problem that the amount of material entering the mold cannot be accurately controlled, resulting in frequent defects such as dimensional deviation and material shortage in the formed data cable outer mold product and low product qualification rate.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Please refer to the attached Figure 1 -Attached Figure 3The embodiment of the present invention provides a molding die for processing a data cable outer mold, including a lower base 1 and a connecting frame 2. The connecting frame 2 is arranged on the top of the lower base 1, so that the upper mold 8 and the lower mold 4 can be accurately aligned. The lower base 1 is provided with a lower mold 4, and a vibration component 5 is arranged at the bottom of the lower mold 4. The upper mold 8 is installed at the bottom of the connecting frame 2, and a quantitative component 3 is arranged on the top of the connecting frame 2, which ensures that the injection material can be filled according to the specified amount, thereby avoiding waste or insufficient materials; The quantitative component 3 includes a hopper 31, which is fixedly connected to the top of the connecting frame 2. A feed barrel 32 is fixedly connected to the top of the hopper 31. Two cylinders 33 are fixedly connected to the outside of the feed barrel 32. The cylinders 33 push the movable ring 34 to transmit the mechanical force to the internal side plate 36 and the blocking plate 37 to achieve the regulation of the material falling channel in the feed barrel 32. The output ends of the two cylinders 33 are respectively fixedly connected to the movable ring 34, and the bottom of the movable ring 34 is fixedly connected to a plurality of connecting columns 35. The connecting columns 35 convert the vertical movement of the movable ring 34 into a swing driving force for the side plate 36.

[0020] Please refer to the attached Figure 3 -Attached Figure 4 , multiple connecting posts 35 are rotatably connected to one end away from the movable ring 34 with multiple side plates 36, and multiple side plates 36 are fixedly connected to one side away from the connecting posts 35 with a blocking plate 37, so that the side plate 36 can convert the linear motion of the connecting posts 35 into the angle change of the side plate 36 with the connection point as the axis, thereby driving the blocking plate 37 to swing downward, thereby controlling the size of the channel for the injection molding material to fall in the feed barrel 32. The movable ring 34 is slidably connected to the outside of the feed barrel 32, providing a stable guide for its vertical movement. Multiple side plates 36 are respectively externally rotatably connected to the inner side wall of the feed barrel 32, and the rotation plane of the side plates 36 can be further limited, so that the side plates 36 can fit closely to the internal space of the feed barrel 32, and effectively block and accurately control the falling of the injection molding material. Multiple blocking plates 37 are arranged inside the feed barrel 32, and the blocking plates 37 are used to quantify the injection molding material, so that the blocking plates 37 can seal and close the feed barrel 32 when not opened, thereby controlling the flow of the injection molding material.

[0021] A discharge pipe 38 is installed on the side of the hopper 31 away from the feed barrel 32. The end of the discharge pipe 38 away from the hopper 31 is fixedly connected to the feed pipe 6. The close connection between the discharge pipe 38 and the hopper 31 ensures that the material can flow smoothly into the feed pipe 6 under the action of gravity, and the quantitative injection molding material is delivered to the molding cavity of the lower mold 4. Two molding cavities are arranged inside the lower mold 4. The end of the feed pipe 6 away from the discharge pipe 38 is fixedly connected inside the molding cavity, which improves the production efficiency of the mold. Two data line outer mold products can be molded in one injection molding process, meeting the market demand for mass production of data line outer molds. A core stick 7 is arranged outside the molding cavity. During the injection molding process, the core stick 7 is precisely matched with the molding cavity to ensure the consistency of the channel size and shape, and improve the practicality and compatibility of the product. The lower base 1 and one side of the lower base 1 are installed and connected with a cylinder 9. The output end of the cylinder 9 is fixedly connected to the connecting plate 10. The cylinder 9 drives the connecting plate 10 to drive the lower mold 4 to move accurately, providing stable power for the opening and closing operation of the mold. Two mounting blocks 11 are fixedly connected to the other side of the connecting frame 2 away from the oil cylinder 9. A rail groove 111 is opened on the opposite side of the two mounting blocks 11. The outside of the connecting plate 10 is slidably connected to the inner wall of the rail groove 111. The mounting blocks 11 and the rail groove 111 provide precise guidance for the sliding of the connecting plate 10, ensuring the precise alignment of the upper and lower molds 4.

[0022] Please refer to the attached Figure 5 -Attached Figure 6 The vibration assembly 5 includes a motor 51, and a rotating rod 52 is fixedly connected to the output end of the motor 51. The motor 51 drives the rotating rod 52 to rotate, providing stable power support for the subsequent circular motion of the cam 53. Two cams 53 are fixedly connected to the outside of the connecting column 35, and two rotating wheels 54 are rotatably connected to the bottom of the lower mold 4. When the rotating rod 52 rotates, the cam 53 performs a circular motion, so that the cam 53 periodically contacts the rotating wheel 54 during the rotation process. At the same time, the friction resistance between the cam 53 and the lower mold 4 is reduced, so that the lower mold 4 can generate a small vibration in the up and down direction under the top pressure of the cam 53.

[0023] Two tension springs 55 are fixedly connected to one side of the bottom of the lower mold 4 away from the rotating wheel 54. The cam 53 contacts the outside of the rotating wheel 54. The end of the tension spring 55 away from the lower mold 4 is fixedly connected to the top of the lower base 1, providing a stable support point for the tension spring 55 to ensure its reliable stretching and contraction. The end of the rotating rod 52 extending to the inside of the lower base 1 is rotatably connected to the inner wall of the lower base 1, ensuring the stable operation of the entire vibration assembly 5, and providing a strong guarantee for improving the quality of the data cable outer mold product.

[0024] Working principle: First, when the entire mold processing flow is started, the mold closing signal is triggered by the external control device, and the upper mold 8 and the lower mold 4 are quickly closed under the action of air pressure to form a sealed space ready to receive material input. The injection material enters the hopper 31 through the top opening of the feed barrel 32. At this time, after the cylinder 33 receives the control system command, its output end pushes the movable ring 34 to slide upward along the outer wall of the feed barrel 32, so that 35 moves upward, and then prompts the side plate 36 to rotate around the connection point with the feed barrel 32. One end of 36 connected to 35 is tilted upward, while the other end of 36 swings downward, and drives the blocking plate 37 to swing downward, so that the size of the falling channel of the injection material in the feed barrel 32 can be controlled, and quantitative control of the injection material entering the hopper 31 can be achieved, avoiding waste of injection material or product defects due to inaccurate dosage; Secondly, a fixed amount of molten plastic is pumped to the flow channel entrance through the hopper 31, and the entire cavity is quickly filled under the action of the pressure difference until it is full. Next, it enters the pressure holding stage, and a certain pressure is maintained for a period of time to ensure that the internal bubbles are completely discharged and the shape is full. During the process of mold closing and injection molding material filling the molding cavity, the motor 51 starts, driving the rotating rod 52 to rotate, so that the two cams 53 perform circular motion accordingly. When the cam 53 rotates, it periodically presses the rotating wheel 54, causing the lower mold 4 to produce slight vibrations in the up and down directions. At the same time, the tension spring 55 plays a buffering and resetting role. When the cam 53 presses the rotating wheel 54 to move the lower mold 4 upward, the tension spring 55 stretches and stores energy; when the cam 53 rotates past the pressing position, the tension spring 55 contracts, pulling the lower mold 4 down and resetting. This periodic vibration can effectively promote the injection molding material to fill and flow more evenly in the molding cavity, discharge bubbles that may exist inside the material, and avoid quality problems such as bubbles and voids in the outer mold of the data cable after molding; Finally, when the temperature drops below the set value and the material hardens, the oil cylinder 9 is activated to drive the connecting plate 10 to move, which guides the core roller 7 along the guide rail to be smoothly pulled out from the inside of the molding cavity, removing obstacles so that the subsequent demolding operation can be completed smoothly. Then, the push rod system applies thrust to open the mold and release the finished product. The whole cycle is repeated continuously.
