Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold used for blanking automobile reinforcement parts. Background Art

[0002] The processing of automobile mold blanking dies mainly includes steps such as part design, CNC machining and mold assembly. Blanking dies play an important role in the processing of automobile parts. They ensure the normal operation of the production line and guarantee the precision and quality of automobile parts.

[0003] A search of the prior art revealed a Chinese patent application numbered 202021382485.2 that discloses a blanking die structure for automotive parts. The patent primarily includes a base, a mounting hole formed on the front of the base, a movable plate movably mounted within the mounting hole, and a limit slot formed on the base at both the top and bottom of the mounting hole. Limit rods are fixedly connected between the inner walls on the left and right sides of the limit slot. While the aforementioned application achieves adjustable positions for both U-shaped and square blades, meeting the needs of automotive parts production, the die only incorporates a mechanism for adjusting the position of the upper blade block, while the position of the blanking hole in the lower die cannot be adjusted synchronously. The lack of a corresponding synchronous adjustment mechanism between the upper blade block position and the blanking hole in the die means the operator may need to adjust the upper and lower dies separately. This separate adjustment method not only increases the complexity and workload of the adjustment, but can also easily lead to deviations in the adjusted positions of the blade block and blanking hole due to human factors or measurement errors, potentially adversely affecting the blanking accuracy and overall quality of the reinforcement. Therefore, those skilled in the art provide a die for blanking automobile reinforcements to solve the problems raised in the above background technology. Utility Model Content

[0025] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5, the utility model embodiment is a mold for blanking automobile reinforcement parts, which includes a base 1 and a mounting plate 4 provided above the base 1, the top of the base 1 is symmetrically fixedly connected to two L-shaped mounting brackets 2, a lower mold 3 of a trapezoidal structure is slidably connected between the mounting brackets 2, an upper mold 5 is slidably connected to the bottom of the mounting plate 4, and a knife block 6 is installed at the bottom of the upper mold 5, and a first positioning component for positioning the lower mold 3 is provided inside the mounting bracket 2, the first positioning component includes a through slot 7 opened inside the mounting bracket 2, a first screw 8 slidably connected to the inside of the through slot 7, and a screw threadedly connected to the outside of the first screw 8 and located at the mounting bracket. The nut on the top of the mounting frame 2, the bottom end of the first screw 8 is fixedly connected to the lower mold 3, and a trapezoidal slide groove 10 is provided on both sides of the mounting plate 4. The side of the mounting plate 4 close to the slide groove 10 is provided with a second positioning component for positioning the upper mold 5. The second positioning component includes a positioning plate 11 fixedly connected to one side of the upper mold 5 and set as an L-shaped structure, a slider 13 slidably connected to the inside of the slide groove 10 and set as a trapezoidal structure, a second screw 14 inserted through the top of the positioning plate 11 and a nut threadedly connected to the outside of the second screw 14, and the end of the second screw 14 close to the slide groove 10 is fixedly connected to the slider 13.

[0026] When the position of the blade block 6 on the upper mold 5 needs to be adjusted, the upper mold 5 is closed with the lower mold 3 so that the blade block 6 is inserted into the blanking hole. The nuts on the first screw 8 and the second screw 14 are loosened, and the position of the slider 13 and the second screw 14 within the chute 10 can be adjusted by moving the upper mold 5. The movement of the upper mold 5 can adjust the position of the blade block 6. When the blade block 6 moves, it synchronously drives the lower mold 3 to move between the mounting brackets 2, and the position of the first screw 8 within the through slot 7 can be adjusted, thereby achieving precise adjustment of the upper mold 5 and the lower mold 3. The upper mold 5 and the lower mold 3 can be positioned by rotating the nuts. The operation is simple, ensuring the consistency and accuracy of the adjustment position of the upper mold 5 and the lower mold 3, and improving the accuracy and efficiency of production.

[0027] In order to facilitate the observation of the moving distance and position of the upper mold 5, a scale line 12 is provided on one of the other two sides of the mounting plate 4. An L-shaped indicator rod 9 is fixedly connected to the middle of the upper mold 5 and close to the scale line 12. The top of the indicator rod 9 extends to one side of the scale line 12.

[0028] During operation, the operator can intuitively understand the movement distance and current position of the upper mold 5 through the cooperation between the indicator rod 9 and the scale line 12, thereby ensuring the accuracy of the installation position and the adjustment position.

[0029] The blade block 6 is bolted to the bottom of the upper die 5 for easy replacement and maintenance. The lower die 3 has a blanking hole inside that works with the blade block 6. Together, they complete the blanking of the reinforcement. The base 1 is designed with a through-hole structure to ensure that after the lower die 3 is adjusted in position, the cut automotive reinforcement will fall to the bottom of the base 1.

[0030] Two first positioning components for positioning the lower mold 3 are symmetrically provided inside the mounting frame 2, and two second positioning components for positioning the upper mold 5 are symmetrically provided on the side of the mounting plate 4 close to the slide groove 10. Multiple first positioning components and second positioning components are set to fix the lower mold 3 and the upper mold 5 to ensure the stability of the installation of the lower mold 3 and the upper mold 5.

[0031] The outside of the base 1 and the mounting plate 4 are symmetrically and equidistantly fixed with four fixing ears, and the inside of the fixing ears are provided with U-shaped grooves, which facilitate the fixing of the entire mold on the workbench and ensure the stability and safety of the mold during operation.

[0032] Working Principle: When the position of the upper blade block 6 of the upper mold 5 needs to be adjusted, the upper mold 5 is closed with the lower mold 3 so that the blade block 6 is inserted into the blanking hole. The nuts on the first screw 8 and the second screw 14 are loosened, and the position of the slider 13 and the second screw 14 within the chute 10 can be adjusted by moving the upper mold 5. The movement of the upper mold 5 can adjust the position of the blade block 6. When the blade block 6 moves, it synchronously drives the lower mold 3 to move between the mounting brackets 2, and the position of the first screw 8 within the through slot 7 can be adjusted, thereby achieving precise adjustment of the upper mold 5 and the lower mold 3. The upper mold 5 and the lower mold 3 can be positioned by rotating the nuts. The operation is simple, ensuring the consistency and accuracy of the adjustment position of the upper mold 5 and the lower mold 3, thereby improving the accuracy and efficiency of production.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
