Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a novel structure for adjusting flatness. Background Technology

[0002] In the field of hardware mold manufacturing, adjusting the flatness of the bending surface of a product is a common and crucial step. Traditional adjustment methods primarily involve raising or lowering the pressure lines of the bending insert, or adjusting the width and shape of the pressure lines. While these methods can improve the flatness of the product to some extent, they are cumbersome, inefficient, and the results are difficult to guarantee. Specifically, traditional adjustment methods require removing the lower mold insert from the mold and sending it to machining equipment for grinding. After machining, the insert must be reinstalled in the mold and a sample is taken for verification. This process often involves multiple disassembly and reassembly, measurement, and repeated testing, wasting significant human and material resources and easily leading to unsatisfactory adjustment results due to human error. Furthermore, excessive or insufficient material removal during grinding can affect the performance and lifespan of the insert, further increasing production costs and mold maintenance difficulty. With the ever-increasing demands for precision and efficiency in industrial manufacturing, traditional mold repair methods can no longer meet the needs of modern manufacturing. These methods are not only inefficient but also require long downtimes, impacting the overall production schedule. Utility Model Content

[0003] To overcome the above shortcomings, the purpose of this utility model is to provide a novel flatness adjustment structure that simplifies the operation process, reduces operation time, lowers manpower and material costs, and achieves precise and rapid flatness adjustment.

[0004] Technical solution: This utility model discloses a novel flatness adjustment structure for calibrating the flatness of a rectangular shielding frame, comprising:

[0005] Upper template, wherein a stripper insert is provided inside the upper template, and the stripper insert is connected and fixed to the upper template;

[0006] The lower template has a lower mold insert block inside it, and the lower mold insert block is connected and fixed to the lower template.

[0007] The fixing screws, at least two in number, are respectively connected to the ejector plate insert and the lower mold insert block, located at the end of the shielding frame, and are used to adjust the flatness of the shielding frame;

[0008] There is a cavity between the lower template and the upper template for accommodating the shielding frame, and the contact surfaces of the lower template and the upper template are both planes.

[0009] Furthermore, the two fixing screws are arranged vertically and are both located at the end of the same corner of the shielding frame.

[0010] Furthermore, the end face of the lower mold insert block facing the ejector plate insert is provided with urethane adhesive, and the fixing screw passes through the urethane adhesive and is connected to the lower mold insert block.

[0011] Furthermore, the end face of the ejector pin facing the lower mold block is provided with urethane adhesive, and the fixing screw passes through the urethane adhesive and is connected to the ejector pin.

[0012] Furthermore, the ejector plate insert is bolted to the upper template, and the lower mold insert block is bolted to the lower template. The two bolts pass through the urethane adhesive and are respectively connected to the ejector plate insert and the lower mold insert block.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) This utility model utilizes the anchor screw to act directly on the end of the shielding frame, and achieves precise flatness control through simple screw adjustment. It does not require complicated processing procedures, significantly shortens the adjustment time, and improves production efficiency.

[0015] (2) The contact surfaces of the upper and lower templates are designed as planar cavities to ensure the stable positioning of the shielding frame and reduce deformation problems caused by structural instability during the stamping process;

[0016] (3) The addition of urethane to this utility model not only serves to fix the screws, but also provides moderate elastic buffering to absorb the micro-vibrations or stresses generated during the stamping process and extend the service life of the mold. Attached Figure Description

[0023] This utility model discloses a novel flatness adjustment structure for calibrating the flatness of a rectangular shielding frame 6, comprising:

[0024] Upper template 1, wherein an ejector insert 11 is provided inside the upper template 1, and the ejector insert 11 is connected and fixed to the upper template 1;

[0025] The lower template 2 has a lower mold insert 21 inside it, and the lower mold insert 21 is connected and fixed to the lower template 2.

[0026] At least two anti-slip screws 3 are provided, which are respectively connected to the ejector plate insert 11 and the lower mold insert block 21, and are located at the end of the shielding frame 6 to adjust the flatness of the shielding frame 6.

[0027] There is a cavity between the lower template 2 and the upper template 1 for accommodating the shielding frame 6, and the contact surfaces of the lower template 2 and the upper template 1 are both planes.

[0028] like Figure 1 and Figure 2As shown, using the above mechanism, the shielding frame 6 is placed into the cavity of the upper template 1 and the lower template 2. One corner of the shielding frame 6 whose flatness needs to be adjusted is placed at the position opposite to the fixing screw 3. If one corner of the shielding frame 6 collapses downward, the fixing screw 3 connected to the lower mold insert 21 needs to be rotated so that the highest point of the fixing screw 3 is higher than the original position. When the upper and lower modules are stamped again, the highest point of the fixing screw 3 abuts against the downward-collapsed corner of the shielding frame 6, and the corner of the shielding frame 6 is adjusted to the preset position through the abutment, thereby achieving the effect of adjusting the flatness of the shielding frame 6. If one corner of the shielding frame 6 tilts upward, the fixing screw 3 connected to the ejector insert 11 needs to be rotated so that the lowest point of the fixing screw 3 is lower than the original position. When the upper and lower modules are stamped again, the lowest point of the fixing screw 3 abuts against the upward-tilted corner of the shielding frame 6, causing the upward-tilted corner to be adjusted downward, thereby achieving the effect of adjusting the flatness of the shielding frame 6.

[0029] Specifically, there is a cavity between the upper and lower modules that can accommodate the shielding frame 6. The flatness adjustment of the shielding frame 6 is completed within the cavity. The contact surface between the upper and lower modules is flat and used for stamping the shielding frame 6. The fixing screw 3 is threaded onto the lower die insert 21 or the ejector insert 11. By rotating the fixing screw 3, the height of the fixing screw 3 protruding from the plane can be controlled. The fixing screw 3 protrudes outward relative to the plane of the upper or lower module, thereby enabling the fixing screw 3 to abut against the shielding frame 6, thus adjusting its flatness.

[0030] In this embodiment, there are at least two fixing screws 3, which are arranged vertically and corresponding to each other. One of them is located on the ejector plate insert 11 in the upper template 1, and the other is located on the lower mold insert block 21 in the lower template 2. The two are aligned vertically and work together on the same corner end of the shielding frame 6 to precisely adjust the flatness of the area. Synchronous adjustment ensures the consistency of the vertical flatness of the adjustment area.

[0031] In this embodiment, urethane adhesive 4 is provided on the end face of the lower die insert 21 facing the ejector plate insert 11. The fixing screw 3 passes through the urethane adhesive 4 and connects to the lower die insert 21. This allows for precise control of the height adjustment of the fixing screw 3 and also prevents the fixing screw 3 from falling off due to weak contact with the shielding frame 6 when it comes into contact with the shielding frame 6 due to impact. The urethane adhesive 4 absorbs vibration and pressure during stamping, reducing mold damage that may be caused by stress concentration and enhancing overall stability. The urethane adhesive 4 on the end face of the ejector plate insert 11 facing the lower die insert 21, with the fixing screw 3 passing through the urethane adhesive 4 and connecting to the ejector plate insert 11, allows for the adjustment of the clamping or corrective force on the shielding frame 6 in the upper structure. The urethane adhesive 4 reduces the rigid contact impact between the fixing screw 3 and the ejector plate insert 11, extending the mold's service life.

[0032] In this embodiment, bolts 5 secure the ejector pin 11 and the lower mold insert 21 to the upper mold plate 1 and the lower mold plate 2 respectively by passing through urethane adhesive 4. The rigid fixation of bolts 5 ensures the robustness of the components, while the elasticity of urethane adhesive 4 provides cushioning, absorbing vibration and impact forces, and reducing stress concentration and fatigue damage to critical mold components. The combined structural design of bolts 5 and urethane adhesive 4 ensures the stability of the ejector pin 11 and the lower mold insert 21 during installation, preventing loosening and misalignment caused by vibration or stress impact.

However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
