Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a precise positioning and demolding mold device for an F-fold shell. Background Technology

[0002] In the fields of electronic equipment and home appliances, F-fold back shells are widely used due to their high structural strength and good assembly adaptability. During their production, multiple small parts need to be processed through continuous stamping. Moreover, the F-fold back shell is not formed by stamping in one go. The stamping accuracy and demolding stability of the small parts directly affect the quality of the final product. These small parts have high dimensional accuracy requirements, and the dimensions and stamping processes of the small parts corresponding to different specifications of F-fold back shells are different.

[0003] However, in existing demolding dies used for continuous stamping of small F-fold back shell parts, the ejector pins are mostly fixed structures, and their extension length cannot be flexibly adjusted. When it is necessary to produce small parts of different specifications and adapt to different demolding heights, the existing dies can only be adapted by replacing the ejector pins of the corresponding specifications or the entire die, which increases the manufacturing cost of the dies and the replacement and maintenance time.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A precision positioning and demolding mold device for an F-fold shell, comprising: The base has a lower mold base at the top. The upper mold base is mounted on the base via a guide mechanism, which guides the upper mold base to move linearly relative to the lower mold base. The stamping mechanism, located between the upper and lower die bases, is used to stamp the F-folded shell parts; The ejector pin has a connecting block at one end and passes through the lower mold base and extends to the stamping area at the other end. An adjustment mechanism is provided at the connection between the ejector pin and the connecting block, and an adjustment component is provided on the ejector pin.

[0011] Furthermore, the guide post is provided with a lubricating oil groove, which is distributed in a spiral shape.

[0012] Furthermore, a positioning element is provided on the lower mold base, which is used for positioning and conveying the sheet metal.

[0018] This application provides a precise positioning and demolding mold device for an F-fold shell, comprising: Base 1, with a lower mold base 2 at the top; The upper mold base 3 is mounted on the base 1 via a guide mechanism 4. The guide mechanism 4 is used to guide the upper mold base 3 to move linearly relative to the lower mold base 2. The stamping mechanism 5 is located between the upper die holder 3 and the lower die holder 2 and is used to stamp the F-fold shell parts; Ejector pin 6 has a connecting block 7 at one end and the other end passes through the lower mold base 2 and extends to the stamping area. An adjustment mechanism 8 is provided at the connection between the ejector pin 6 and the connecting block 7. Multiple ejector pins 6 are provided on the connecting block 7, and adjustment components are provided on the ejector pin 6. Spring 9 is sleeved on ejector pin 6. Spring 9 is located between connecting block 7 and lower mold base 2 and is used to provide upward elastic force to ejector pin 6. Through the technical solution of this utility model, the guiding mechanism 4 guides the upper mold base 3 to move linearly relative to the lower mold base 2, and cooperates with the stamping mechanism 5 to realize the stamping forming of the F-fold back shell parts, avoiding stamping deviation. One end of the ejector pin 6 is linked through the connecting block 7, and the other end extends to the stamping area. The adjusting component is used to adjust the activity range of the ejector pin 6. The elastic force provided by the spring 9 pushes the ejector pin 6 to eject the workpiece after stamping, ensuring continuous stamping. The connecting block 7 ensures that multiple ejector pins 6 move synchronously. The adjusting mechanism 8 flexibly adjusts the assembly position of the ejector pin 6 and the connecting block 7 to adapt to the demolding requirements of different specifications of F-fold back shells, improve product yield, and increase continuous stamping production efficiency.

[0019] During use, the stamping mechanism 5 includes: The stamping head 51 is located at the bottom of the upper die holder 3; The stamping base 52 is located at the bottom end of the lower die base 2, and the stamping head 51 is correspondingly arranged with the stamping base 52; Cylinder 53, mounted on upper die base 3, is used to drive stamping head 51 to move linearly and stamp the F-folded back shell part. Through the technical solution of this utility model, the stamping head 51 and the stamping seat 52 are set in correspondence to meet the stamping forming requirements of the F-fold shell accessory, ensuring the forming accuracy of the workpiece. The cylinder 53 provides linear driving force for the stamping head 51, which is suitable for the high-frequency operation scenario of continuous stamping. It works in conjunction with the demolding structure of the ejector pin 6 and the connecting block 7 to improve the continuous production cycle.

[0020] In the above embodiment, the adjusting mechanism 8 includes: One end of the threaded rod 81 is fixedly connected to the connecting block 7; The adjusting screw tube 82 is fixedly installed on the ejector pin 6, and the adjusting screw tube 82 is connected to the threaded rod 81. A locking element 83 is provided on the threaded rod 81, and the locking element 83 abuts against the adjusting screw tube 82; Through the technical solution of this utility model, the threaded rod 81 and the adjusting screw tube 82 are threadedly engaged to adjust the extension length of the ejector pin 6, which can be adapted to the demolding height requirements of different specifications of F-fold shells. The locking part 83 abuts against the adjusting screw tube 82 to lock the adjusted position, preventing the ejector pin 6 from loosening or shifting during demolding, and further improving the product yield.

[0021] During use, the head of the ejector pin 6 near the stamping area has an arc-shaped structure; Through the technical solution of this utility model, the arc-shaped structure of the ejector pin 6 head avoids scratching the workpiece surface. Its arc-shaped contour can fit the curved surface and corner structure of the F-fold shell, so that the force is more even when the ejector pin 6 pushes, preventing the workpiece from deforming due to local force concentration. At the same time, it reduces demolding resistance and avoids jamming. With the synchronous displacement driven by the connecting block 7 and the elastic pushing force of the spring 9, the demolding action is guaranteed to be smooth and efficient. It is suitable for continuous stamping high-frequency operation scenarios and further improves product yield and production stability.

Through the technical solution of this utility model, the guide post 41 and the guide sleeve 42 slide correspondingly, guiding the upper mold base 3 to move linearly relative to the lower mold base 2, avoiding the upper mold base 3 from shifting during stamping, ensuring the fitting accuracy of the stamping groove between the stamping head 51 and the stamping seat 52, reducing the forming deviation of the shell after F-folding, and the spiral lubricating oil groove on the guide post 41 can stably store lubricating oil, continuously lubricating the mating surface between the guide post 41 and the guide sleeve 42, reducing sliding friction loss, improving the smoothness of the opening and closing action, and extending the service life of the guide mechanism 4.

[0023] During use, a positioning element 10 is provided on the lower mold base 2, which is used for positioning and conveying the sheet metal. Through the technical solution of this utility model, the positioning component 10 positions and smoothly conveys the sheet metal, ensuring that the sheet metal accurately enters the stamping groove of the stamping seat 52, avoiding the deviation of the shell forming size caused by the offset of the sheet metal. The positioning and conveying function makes the sheet metal feeding smoother and adapts to the high-frequency operation requirements of continuous stamping.
