Description

Technical Field

[0001] This utility model relates to the field of molding die technology, and in particular to a rapid prototyping die for a wear-resistant conductive sheet. Background Technology

[0002] Loss-resistant conductive sheets are conductive material components that maintain good conductivity and have low physical loss during long-term use. They are mainly used in electronic devices, serving as bridges connecting different electronic components in the circuit connection part of computer motherboards to realize the transmission of signals and current. In power adapters, conductive sheets can effectively transmit electrical energy from external power sources to the internal circuitry of the device. Stamping is the most common process for manufacturing conductive sheets. First, a metal sheet is placed in a stamping die, and pressure is applied by a press to shape the sheet according to the die. Stamping can efficiently produce conductive sheets with complex shapes and high precision.

[0003] In the current production process of conductive sheets, stamping dies play a crucial role and are one of the most commonly used die types. Their working principle is based on the pressure applied by a press, which causes the punch and die to precisely stamp the pre-prepared metal sheet into the specific shape of the desired conductive sheet. Stamping dies are widely used in industrial production due to their high production speed, enabling the mass production of conductive sheets that meet specifications in a short time, satisfying market demand. They also possess high precision; through precise die design and manufacturing processes, the produced conductive sheets can achieve high precision standards. However, after stamping, the conductive sheet often becomes tightly stuck in the die cavity, making it difficult to remove smoothly. Attempting to remove it by hand can result in the hand being caught, increasing the danger of the removal process and affecting production efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rapid prototyping mold for wear-resistant conductive sheets, which aims to improve the problem in the prior art where, after stamping, the conductive sheet is tightly stuck in the mold cavity and difficult to remove smoothly. If the sheet is removed by hand, it will cause the hand to be pinched, increasing the danger of the demolding process and affecting production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rapid prototyping mold for loss-resistant conductive sheets, comprising a lower base plate, a lower template fixedly connected to the top surface of the lower base plate, guide posts fixedly connected to the four corners of the top surface of the lower base plate, a slide rail slidably connected to the outer wall of the guide posts, a top plate fixedly connected to the outer wall of the slide rail, a pad fixedly connected to the bottom surface of the guide posts, an upper template fixedly connected to the bottom surface of the pad, a top post fixedly connected to the bottom surface of the upper template, and an ejection mechanism provided at one end of the top surface of the lower base plate, the ejection mechanism being used to eject the finished product.

A magnet is fixedly connected to the top of the sliding column, a fixing column is fixedly connected to the bottom surface of the top plate, and a magnet is fixedly connected to the bottom surface of the fixing column. A push rod is rotatably connected to the middle of the sliding column via a U-shaped block, and a connecting block is rotatably connected to the middle of the push rod. The bottom surface of the connecting block is fixedly connected to the top surface of the lower base plate.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when rapidly forming conductive sheets, the material is first placed on the top surface of the lower template to ensure stability. The press is then used to slowly press down the top plate. Guide pillars and slide rails assist in the precise positioning and guidance of the upper and lower templates, ensuring positional matching during stamping. The material is stamped according to the predetermined shape and size to form a preliminary conductive sheet product. After stamping is completed, the top plate is lifted, the spring inside the mold releases its elastic potential energy, and the unloading plate slides smoothly along the guide pillars to remove the formed conductive sheet from the mold, achieving preliminary separation and laying the foundation for the unloading operation.

[0022] 2. In this utility model, when the top plate rises, magnet two attracts magnet one, pushing the sliding column to slide up the track, driving the left end of the push rod to rise, so that the conductive sheet slides out of the mold. The top plate continues to rise to the height limit of the limiting block, magnet one disconnects from the fixed column, the sliding column slides down and returns to the initial position, completing the stamping and unloading, ensuring production efficiency and continuity.

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.

[0031] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of a rapid prototyping mold for a wear-resistant conductive sheet, comprising a lower base plate 1, a lower template 3 fixedly connected to the top surface of the lower base plate 1, the lower template 3 providing a crucial cavity foundation for the forming of the conductive sheet, guide pillars 4 fixedly connected to the four corners of the top surface of the lower base plate 1, slide rails 9 slidably connected to the outer walls of the guide pillars 4, and a top plate 5 fixedly connected to the outer walls of the slide rails 9, allowing the top plate 5 to move smoothly up and down along the guide pillars 4, providing strong support for the mold closing and opening actions, a pad 6 fixedly connected to the bottom surface of the guide pillars 4, an upper template 7 fixedly connected to the bottom surface of the pad 6, and a top pillar 8 fixedly connected to the bottom surface of the upper template 7, and an ejection mechanism 2 provided at one end of the top surface of the lower base plate 1, the ejection mechanism 2 being used to eject the finished product.

[0032] Please see the appendix Figure 4 - Appendix Figure 5 The pop-out mechanism 2 includes a sliding column 201, the outer wall of which is slidably connected to the inner wall of the lower base plate 1. The sliding column 201 can flexibly reciprocate within the lower base plate 1. A magnet 202 is fixedly connected to the top of the sliding column 201. A fixing column 203 is fixedly connected to the bottom surface of the top plate 5. A magnet 204 is fixedly connected to the bottom surface of the fixing column 203. A push rod 207 is rotatably connected to the middle of the sliding column 201 via a U-shaped block 206. A connecting block 205 is rotatably connected to the middle of the push rod 207. The bottom surface of the connecting block 205 is fixedly connected to the top surface of the lower base plate 1.

[0033] Please see the appendix Figure 1 - Appendix Figure 3The top plate 5 is fixedly connected to the outer wall with a handle 11, and the top surface of the top plate 5 is fixedly connected to a nameplate 10 for easy identification and management of the mold. The bottom surface of the bottom plate 1 is fixedly connected to four corners with fixed feet 13. The fixed feet 13 can stably support the mold on the worktable, and the mold can be kept horizontal by adjusting the height of the fixed feet 13 to ensure the accuracy of the molding process. The outer wall of the lower template 3 is fixedly connected to a heat dissipation box 22, which can effectively absorb and dissipate heat to prevent the mold temperature from being too high and affecting the molding quality of the conductive sheet and the service life of the mold. The lower template 3 is fixedly connected to the top surface of the lower bottom plate 1 by screws 12. The bottom surface of the sliding column 201 is fixedly connected to a limit block 19 to limit the sliding stroke of the sliding column 201.

[0034] Please see the appendix Figure 3 - Appendix Figure 5 The top of the screw 12 is fixedly connected to a cap 20, and the top surface of the cap 20 is provided with a hexagonal groove 21 to facilitate the assembly and disassembly of the mold. The top surface of the lower base plate 1 is fixedly connected to an air pipe 17, and the top of the air pipe 17 is connected to a nozzle 18, which can effectively remove dust, impurities and waste material after demolding inside the cavity and keep the cavity clean. The bottom surface of the upper template 7 is fixedly connected to a guide post 14, and the outer wall of the guide post 14 is slidably connected to a stripper plate 16. The outer wall of the guide post 14 is provided with a spring 15. As the upper template 7 rises, the stripper plate 16 can separate the formed conductive sheet from the cavity under the action of the spring 15.

[0035] Working principle: When rapid prototyping of conductive sheets is required, the raw material is first placed on the top surface of the lower template 3 to ensure stable position. The press is used to slowly press the top plate 5 downward. The guide post 4 and slide rail 9 provide precise auxiliary positioning and guiding functions for the relative movement of the upper template 7 and the lower template 3, ensuring that the positions of the two can be perfectly matched during the stamping process, so that the raw material can be stamped into the predetermined shape and size to obtain the initial conductive sheet product. After the stamping is completed, the top plate 5 begins to lift upward. At this time, the spring 15 inside the mold is in a compressed state due to the pressure of the top plate 5 pressing down. At this moment, the elastic potential energy is released, pushing the unloading plate 16 to slide down quickly and smoothly along the guide post 14, and smoothly unloading the stamped conductive sheet from the mold. The separation of the conductive sheet from the mold is initially realized, laying the foundation for the subsequent unloading operation.

[0036] As the top plate 5 continues to rise, the second magnet 204 inside the mold will attract the first magnet 202 under the action of magnetic force. As the top plate 5 rises, it drives the sliding column 201 to slide upward along the predetermined track, thereby causing the left end of the push rod 207 to move upward. Since the middle part of the push rod 207 is rotatably connected to the top surface of the lower base plate 1 through the connecting block 205, when the right end of the push rod 207 moves upward, the left end will extend to the left, pushing the newly formed conductive sheet to gradually slide out of the mold. As the top plate 5 continues to rise, when it reaches a certain height, the limiting block 19 will play its limiting role, making the sliding column 201 unable to rise further. The connection between the first magnet 202 and the fixed column 203 is broken. After losing the upward power support, the sliding column 201 will slide down under the action of gravity and return to the initial position, ready for the next stamping and unloading operation. This completes the rapid forming and unloading process of the conductive sheet, ensuring the efficiency and continuity of the production process.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
