Description

Technical Field

[0002] The D-pillar lower outer panel weldment, together with the D-pillar upper outer panel, rear end panel, and side panel, forms a closed exterior body surface. It provides positioning and mounting points for the taillights, rear fascia bracket, and tailgate stopper. This structure provides structural space for the taillights and is a critical component of the vehicle body. Therefore, the D-pillar lower outer panel weldment serves as the foundation for the installation and positioning of the taillights and rear fascia, two rear exterior components. The precision and structure of this component significantly impact the shape and structure of the taillights, the DTS at the rear of the vehicle, and the vehicle's sealing. The existing technology presents the following problems:

[0003] Because the existing D-pillar outer panel side is mainly formed by integral stamping of metal parts, and the forming process requires the use of a male mold and a female mold to squeeze each other to press out the shape of the outer panel side. However, after stamping, the two molds are often too tight, and the D-pillar outer panel is easily stuck in the female mold, and needs to be removed manually, resulting in reduced stamping efficiency. At the same time, the existing forming molds generally use hot stamping technology for the D-pillar outer panel metal parts. The D-pillar outer panel metal parts need to maintain a certain temperature during stamping to ensure surface hardness, dent resistance and rigidity, and to avoid rebound problems. However, the D-pillar outer panel metal parts stamped at high temperature still need to be cooled for a long time before they can be used, which also causes the problem of reduced production efficiency.

The upper pressing male mold plate 24 has four elastic Spring compartment 241, the bottom of the inner wall of the four spring compartments 241 are fixedly installed with return springs 242, the tops of the four return springs 242 are fixedly installed with placement rod bottom plates 243, the tops of the four placement rod bottom plates 243 are fixedly installed with metal plate placement rods 244, the tops of the four metal plate placement rods 244 all pass through the top of the upper pressing male mold plate 24, the four metal plate placement rods 244 are distributed in groups of two on the front and back sides of the center of the upper pressing male mold plate 24, the upper pressing male mold plate 24 is provided with a push rod compartment 245, the inner cavity of the push rod compartment 245 is fixedly installed with an electric push rod 246, the output end of the electric push rod 246 passes through the left side of the upper pressing male mold plate 24 and is fixedly installed with a C-type plate 247, the vertical part of the C-type plate 247 is provided with a left and right through air leakage hole 248, the left C-type blowing pipe 64 can blow to the metal parts through the air leakage hole 248;

[0023] When the side of the D-pillar outer panel is press-formed, the unprocessed metal plate is placed on the top of the four metal plate placement rods 244 extending from the top of the upper pressing male mold plate 24. The center of its bottom can also be overlapped and placed by relying on the mold protrusion at the center of the top of the upper pressing male mold plate 24, so that it is placed stably. Then the hydraulic cylinder 22 at the top center of the mold base 21 can be directly started to drive the upper pressing male mold plate 24 to rise, and at the same time, the hydraulic telescopic rod 23 is used to extend and retract to maintain the stability of the upper pressing male mold plate 24 when it rises, and finally the upper pressing male mold plate 24 is docked with the bottom of the fixed female mold 5.

[0024] like Figure 4As shown, a stamping groove 51 is provided at the bottom center of the fixed mother mold 5, and a lower pressure chamber 52 is provided in the fixed mother mold 5. A fixing rod 521 is fixedly installed at the bottom of the inner wall of the lower pressure chamber 52, and a lifting plate 522 is slidably installed on the outer wall of the fixing rod 521. A compression spring 523 is fixedly installed at the bottom of the lifting plate 522. The fixing rod 521 is located on the inner side of the compression spring 523, and a limit block 524 is fixedly installed on the top of the fixing rod 521. A snap box 525 is fixedly installed on the left end of the lifting plate 522, and a snap box 525 is fixedly installed on the right side of the inner wall of the snap box 525. A buckle spring 526 is fixedly installed on the left end of the buckle spring 526 with a buckle base plate 527, and a bevel buckle 528 is fixedly installed on the left side of the buckle base plate 527.

The bottom of the arc push plate 532 passes through the inner cavity of the stamping groove 51 and is aligned with the top of the inner wall of the stamping groove 51.

[0025] When merging, the horizontal part above the C-shaped plate 247 on the left side of the upper pressing male mold plate 24 will squeeze the inclined surface below the inclined surface buckle 528 protruding on the left side of the fixed female mold 5, so that the inclined surface buckle 528 uses the buckle bottom plate 527 to squeeze the buckle spring 526 back into the inner cavity of the buckle box 525. After complete merging, the C-shaped plate 247 will be located above the inclined surface buckle 528. At this time, the horizontal part above the inclined surface buckle 528 is used to limit the C-shaped plate 247. When discharging, the upper pressing male mold plate 24 drives the C-shaped plate 247 to descend, and the C-shaped plate 247 will be used to pull the entire mold downward. The body snap box 525 drives the lifting plate 522 to slide downward on the outer wall of the fixed rod 521 and squeeze the compression spring 523, while driving the L-shaped pressure plate 53 and the arc push plate 532 at the bottom end of the connecting rod 531 to move downward, pushing out the metal parts stuck in the stamping groove 51 to complete the discharge. When the upper pressing male mold plate 24 is about to reach the bottom, the electric push rod 246 can be started to drive the C-shaped plate 247 to move to the left, releasing the limit on the inclined snap 528, so that the snap box 525 is reset under the rebound of the compression spring 523, and the arc push plate 532 is reset at the same time.

[0026] like Figure 5 As shown, the heat dissipation mechanism 6 includes a fixed vertical plate 61, which is fixedly mounted on the top rear side of the connecting plate 4. A blower 62 is fixedly mounted on the front side of the fixed vertical plate 61. The output end of the blower 62 is fixedly connected to a shunt pipe 63. The left and right ends of the shunt pipe 63 are fixedly connected to C-shaped blowing pipes 64. The opposite ends of the two C-shaped blowing pipes 64 at the lower horizontal position respectively penetrate the opposite surfaces of the two vertical plate frames 3.

[0027] When the press-formed metal parts are discharged, the blower 62 on the front side of the fixed vertical plate 61 can be started to use the C-shaped blowing pipe 64 connected to the two ends of the diversion pipe 63 to blow air to dissipate heat, quickly lowering the temperature and thus reducing the subsequent cooling time.

[0028] The following specifically describes the working principle of the D-pillar outer panel side press-forming die.

[0029] like Figure 1-5 As shown, when the side of the D-pillar outer panel is press-formed, the unprocessed metal plate is placed on the top of the four metal plate placement rods 244 extending from the top of the upper press male mold plate 24, and its bottom center can also be overlapped and placed by relying on the mold protrusion at the top center of the upper press male mold plate 24, so that it is placed stably. Then, the hydraulic cylinder 22 at the top center of the mold base 21 can be directly started to drive the upper press male mold plate 24 to rise, and at the same time, the hydraulic telescopic rod 23 is extended to keep the upper press male mold plate 24 rising. The stability of the upper pressing male mold plate 24 is finally docked with the bottom of the fixed female mold 5, and the shape is pressed out by the stamping groove 51. When merging, the upper horizontal part of the C-shaped plate 247 on the left side of the upper pressing male mold plate 24 will squeeze the lower inclined surface of the inclined surface buckle 528 protruding on the left side of the fixed female mold 5, so that the inclined surface buckle 528 uses the buckle bottom plate 527 to squeeze the buckle spring 526 back into the inner cavity of the buckle box 525. After complete merging, the C-shaped plate 247 will be located above the inclined surface buckle 528. At this time, the inclined surface buckle 528 is squeezed back to the inner cavity of the buckle box 525 by the buckle bottom plate 527. The C-shaped plate 247 is limited at the horizontal position above the surface buckle 528. When discharging, the upper pressing male mold plate 24 drives the C-shaped plate 247 to descend, and the C-shaped plate 247 is used to pull the integral buckle box 525 downward, thereby driving the lifting plate 522 to slide downward on the outer wall of the fixed rod 521 and squeeze the compression spring 523, while driving the L-shaped pressing plate 53 and the arc push plate 532 at the bottom end of the connecting rod 531 to move downward, pushing out the metal parts stuck in the stamping groove 51 to complete the discharging, and the upper pressing male mold plate 24 When it is about to reach the bottom, the electric push rod 246 can be started to drive the C-shaped plate 247 to move to the left, thereby releasing the limit on the inclined buckle 528, so that the buckle box 525 is reset under the rebound of the compression spring 523, and the arc push plate 532 is reset at the same time. When the metal part formed by the upper pressure is discharged, the blower 62 on the front side of the fixed vertical plate 61 can be started to use the C-shaped blowing pipe 64 connected to the two ends of the diversion pipe 63 to blow air and dissipate heat. At the same time, the C-shaped blowing pipe 64 on the left can blow towards the metal part through the air leakage hole 248.

[0030] While the present invention has been generally described above, it is readily apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are intended to be within the scope of protection of the present invention.
