Description

Technical Field

[0001] This invention relates to the field of automotive mold flanging technology, and in particular to a flanging ejection mechanism for automotive molds. Background Technology

[0002] In the automotive manufacturing industry, the flanging process of body panels, frame structures and other workpieces is a key forming process that directly affects the assembly accuracy and structural strength of automotive parts. As the automotive market continues to demand higher production efficiency, workpiece quality and automation levels, improving the feeding, flanging and ejection aspects of traditional automotive mold flanging devices is one of the means to adapt to the needs of modern assembly line production.

[0003] Place the car part on the lower mold, push the upper mold towards the lower mold, and the upper and lower molds work together to flip the workpiece. After the upper mold leaves the lower mold, there is a risk that the workpiece will be lifted by the upper mold. Manually use an iron rod to pry it off, and finally remove the workpiece from the mold and place the next flipped workpiece in the lower mold.

[0004] In the existing flanging and ejection mechanisms of automotive molds, traditional ejection mechanisms mostly use a single ejector rod or a partial ejection structure. Although they can eject the workpiece, the ejection force is unevenly distributed, which can easily lead to workpiece deformation due to force imbalance, or even workpiece sticking to the mold. Therefore, a flanging and ejection mechanism for automotive molds is proposed. Summary of the Invention

[0012] As a preferred embodiment of the flange ejector mechanism for automotive molds described in this invention, the lower mold has elongated grooves evenly distributed on one side to fit the ejector bar, and square grooves evenly distributed on both sides of the inner surface of the elongated grooves to fit the limiting plate. The ejector bar and the limiting plate are slidably connected inside the elongated groove and the square groove, respectively. The bottom of the ejector rod is an inclined surface, and the top of the ejector bar has inclined grooves evenly distributed to fit the inclined surface of the ejector rod.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Example

[0029] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a flanging and ejection mechanism for an automotive mold, comprising: Support 1; The flanging mechanism 2 is located on the top of the support base 1. The flanging mechanism 2 includes a base 201 located on the top of the support base 1. A lower mold 202 is installed on the top of the base 201. Multiple slide rods 203 are evenly distributed on the top of the support base 1. A lower pressure plate 205 is movably installed on the outer surface of the slide rods 203 through a linear bearing. An upper mold 206 adapted to the lower mold 202 is installed at the bottom of the lower pressure plate 205.

[0030] like Figure 2 and Figure 3 As shown, in this embodiment, the lower pressure plate 205 has through holes at its four top corners that are adapted to the slide rod 203. The lower pressure plate 205 is slidably connected to the outside of the slide rod 203 by linear bearings installed inside the through holes. The lower mold 202 is located directly below the upper mold 206. The lower pressure plate 205 slides on the slide rod 203 by linear bearings. The linear bearings minimize the friction between the slide rod 203 and the lower pressure plate 205. Multiple slide rods 203 ensure that the lower pressure plate 205 can move in the vertical direction. With the cooperation of the upper mold 206 and the lower mold 202, the automotive workpiece is flanged.

[0031] like Figure 2 and Figure 3 As shown, in this embodiment, a top cover 204 is installed on the top of the slide bar 203, and a stamping cylinder 210 is installed at the center of the top of the top cover 204. Damping rods 207 are installed at the four corners inside the upper mold 206, and positioning blocks 208 are installed at the bottom of the damping rods 207. A first spring 209 is provided on the top of the positioning blocks 208. During the operation of the stamping cylinder 210, it provides the lower pressure plate 205 with the power to move in the vertical direction, which can push the upper mold 206 towards the lower mold 202 to perform the flanging operation on the workpiece, thereby applying a downward pushing force to the upper mold 206.

[0032] like Figure 2 and Figure 3 As shown, in this embodiment, the upper mold 206 has a circular groove inside that is adapted to the positioning block 208. The damping rod 207 is installed inside the positioning block 208, and the first spring 209 is located outside the damping rod 207. The positioning block 208 is slidably connected inside the circular groove. When the upper mold 206 is pushed downward, the positioning block 208 first contacts the top of the workpiece. Under the action of the first spring 209, a pushing force is applied to the positioning block 208 towards the top of the workpiece. Under the action of multiple positioning blocks 208, the workpiece is first positioned to prevent displacement of the workpiece during the flanging process, thus stabilizing the workpiece.

[0033] Furthermore, the workpiece to be flanged is placed on the lower mold 202, and the stamping cylinder 210 is controlled to run. The output end of the stamping cylinder 210 drives the lower pressure plate 205 to move outward outside the multiple slide bars 203. The lower pressure plate 205 drives the upper mold 206 to move towards the lower mold 202. When the upper mold 206 is about to contact the workpiece, multiple positioning blocks 208 first contact the top of the workpiece. Under the action of multiple first springs 209, the corresponding positioning blocks 208 are pushed towards the top of the workpiece. Several positioning blocks 208 first apply pressure to the workpiece, positioning the workpiece on the top of the lower mold 202. Then the upper mold 206 continues to move towards the lower mold 202. With the cooperation of the upper mold 206 and the lower mold 202, the workpiece is flanged. After the flanging is completed, the upper mold 206 moves upward along the slide bar 203. Under the action of multiple first springs 209, the workpiece is pushed out from the bottom of the upper mold 206 in the same way as above, preventing the workpiece from sticking to the upper mold 206, thus completing the workpiece flanging operation. Example

[0034] Reference Figures 4-6 This is the second embodiment of the present invention, which is based on the previous embodiment. The ejector mechanism 3 is disposed inside the lower mold 202. The ejector mechanism 3 includes push bars 301 evenly distributed inside the lower mold 202. A plurality of push rods 302 are evenly distributed inside the lower mold 202. A limiting circular plate 303 is installed on the top of the push rod 302. A rubber plate 304 is installed on the top of the limiting circular plate 303. A push rod 309 is installed on one side of the push bar 301.

[0035] like Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the top of the lower mold 202 is provided with several limiting grooves adapted to the limiting circular plate 303, and the bottom of the limiting groove is provided with a T-shaped groove adapted to the ejector rod 302. The limiting circular plate 303 and the rubber plate 304 are slidably connected to the ejector rod 302 in the limiting groove and the T-shaped groove, respectively. When the ejector rod 302 is pushed upward, the limiting circular plate 303 pushes the rubber plate 304 vertically upward. Since the rubber plate 304 is made of rubber, it will not damage the workpiece when it pushes the bottom of the workpiece. Furthermore, under the action of several rubber plates 304, an upward force is applied to the bottom of the workpiece at the same time, so that the workpiece is subjected to uniform force and plays a role in stabilizing the ejection.

[0036] like Figure 4 , Figure 5 and Figure 6As shown, in this embodiment, multiple limiting plates 307 are evenly distributed on both sides of the push bar 301, a limiting ring 306 is installed on the outer surface of the push rod 302, a second spring 305 is provided on the top of the limiting ring 306, a mounting seat 308 is installed on one side of the base 201, a first cylinder 310 is installed inside the mounting seat 308, the limiting ring 306 is slidably connected inside the T-shaped groove, and the output end of the first cylinder 310 is installed at the center of one side of the push rod 309. The second spring 305 is located in the inner cavity of the T-shaped groove and outside the push rod 302. Under the action of the second spring 305, a downward pushing force is applied to the limiting ring 306. When the push rod 302 is not subjected to external force, the limiting circular plate 303 and the rubber plate 304 at the top of the push rod 302 are located in the limiting groove, and the top of the rubber plate 304 is kept at the same level as the inner surface of the lower mold 202.

[0037] like Figure 4 , Figure 5 and Figure 6 As shown in this embodiment, the lower mold 202 has elongated grooves evenly distributed on one side to fit the pusher 301. Square grooves evenly distributed on both sides of the inner surface of the elongated grooves to fit the limiting plate 307 are provided. The pusher 301 and the limiting plate 307 are slidably connected inside the elongated groove and the square groove, respectively. The bottom of the pusher 302 is inclined, and the top of the pusher 301 has inclined grooves evenly distributed to fit the inclined surface of the pusher 302. The inclined surface of the pusher 302 fits into the inclined groove corresponding to the pusher 301. Under the action of multiple limiting plates 307, the pusher 301 moves stably. When the pusher 301 is pushed horizontally, the pusher 302 can be lifted upward to push the material.

[0038] Furthermore, after the flanging is completed, the first cylinder 310 is controlled to operate. The output end of the first cylinder 310 pushes the push rod 309 laterally downward toward the mold 202. With the assistance of multiple push bars 301 corresponding to the limiting plate 307, the push rod 309 simultaneously pushes multiple push bars 301 to move. The push bars 301 push the inclined surface of the ejector rod 302 from the inclined groove to the horizontal plane. During this process, several ejector rods 302 move upward at the same time. The ejector rods 302 drive the limiting ring 306 to apply a compressive force to the second spring 305, causing it to deform. Then the ejector rods 302 pass through the limiting ring. The circular plate 303 drives the rubber plate 304 to move upward. Several rubber plates 304 simultaneously apply an upward pushing force to the workpiece at the top of the lower mold 202, thus ejecting the workpiece. The first cylinder 310 is controlled to operate, with the same principle as above, so that the inclined groove of the push bar 301 is located directly below the inclined surface of the ejector rod 302. At this time, under the action of the second spring 305, a downward pushing force is applied to the limiting ring 306, so that the inclined surface of the ejector rod 302 contacts the corresponding inclined groove of the push bar 301. At this time, the rubber plate 304 and the inner surface of the lower mold 202 are at the same level, preparing for the subsequent ejection. Example

[0039] Reference Figure 7 and Figure 8 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment. The feeding mechanism 4 is disposed inside the support base 1. The feeding mechanism 4 includes a lead screw 401 that is movably installed at the center of the inside of the support base 1 through a bearing seat. An adjusting block 402 adapted to the lead screw 401 is installed at the center of the bottom of the base 201. Double-plate follower wheels 403 are installed at the four corners of the bottom of the base 201.

[0040] like Figure 7 and Figure 8 As shown, in this embodiment, the top of the support base 1 is provided with a T-shaped groove adapted to the adjusting block 402. The adjusting block 402 is slidably connected inside the T-shaped groove. The top of the support base 1 is symmetrically provided with slides adapted to the double-plate follower wheels 403. The double-plate follower wheels 403 are slidably connected inside the slides. The adjusting block 402 is movably installed on the outside of the lead screw 401 through a threaded sleeve. Since the double-plate follower wheels 403 are installed at the four corners of the bottom of the base 201, the two horizontal double-plate follower wheels 403 form a group. Each group of double-plate follower wheels 403 moves in the corresponding slide. When the lead screw 401 drives the adjusting block 402 to move, it plays a role in stabilizing the movement of the base 201.

[0041] like Figure 7 and Figure 8 As shown, in this embodiment, the feeding mechanism 4 also includes a fixing plate 404 symmetrically installed on the top of the support base 1. A fixing block 405 is installed on one side of the fixing plate 404. A second cylinder 406 is installed inside the fixing block 405. A stop block 407 is installed at the output end of the second cylinder 406. A motor 408 is installed at one end of the lead screw 401 extending to the outside of the support base 1. Both stop blocks 407 are located outside the base 201. Folding plates are installed at the T-shaped slide and the slide. After the lower mold 202 moves to directly below the upper mold 206, the two stop blocks 407 are locked on the outside of the base 201. With the cooperation of the double-plate follower wheel 403 and the stop blocks 407, the base 201 is fixed at this position to ensure stable flanging of the workpiece.

[0042] Furthermore, the operation of two second cylinders 406 is controlled simultaneously. The two second cylinders 406 drive the corresponding stop blocks 407 to move, moving the two stop blocks 407 out from one side of the base 201. The operation of the motor 408 is controlled, and the output end of the motor 408 drives the lead screw 401 to rotate. The lead screw 401 drives the adjusting block 402 to move inside the support base 1. With the assistance of multiple double-plate follower wheels 403, the adjusting block 402 drives the base 201 to move. The base 201 drives the lower mold 202 to move, moving the lower mold 202 to one side of the top of the support base 1. The flanging workpiece is placed on the lower mold 202. The operation of the motor 408 is controlled, and the principle is the same as above, moving the lower mold 202 directly below the upper mold 206. The two second cylinders 406 push the corresponding stop blocks 407 to one side of the base 201, fixing the base 201 in that position. Finally, the workpiece is flanged.

[0043] Working principle: The device is connected to an external power supply and controller via a wiring harness. Simultaneously, two second cylinders 406 are controlled to operate. Each second cylinder 406 moves its corresponding stop 407, moving the two stop 407 out from one side of the base 201. This controls the motor 408 to operate, and the output of the motor 408 drives the lead screw 401 to rotate. The lead screw 401 drives the adjusting block 402 to move inside the support base 1. With the assistance of multiple double-plate follower wheels 403, the adjusting block 402 moves the base 201, which in turn moves the lower mold 202, moving it to the top side of the support base 1. The flanged workpiece is then placed on the lower mold 202. The motor 408 is then controlled to operate, and the principle is the same as above, moving the lower mold 202... 2. Move to directly below the upper mold 206. The two second cylinders 406 push the corresponding stops 407 to one side of the base 201, fixing the base 201 in place. Control the operation of the stamping cylinder 210. The output end of the stamping cylinder 210 drives the lower pressure plate 205 to move outward outside the multiple slide bars 203. The lower pressure plate 205 drives the upper mold 206 to move towards the lower mold 202. When the upper mold 206 is about to contact the workpiece, multiple positioning blocks 208 first contact the top of the workpiece. Under the action of multiple first springs 209, the corresponding positioning blocks 208 are pushed towards the top of the workpiece. Several positioning blocks 208 first apply pressure to the workpiece, positioning the workpiece on the top of the lower mold 202. Then the upper mold 206 continues to move towards the lower mold 202. The workpiece is flanged by the cooperation of the upper mold 206 and the lower mold 202. After flanging, the upper mold 206 moves upward along the slide bar 203. Under the action of multiple first springs 209, the workpiece is pushed out from the bottom of the upper mold 206 to prevent it from sticking to the upper mold 206, thus completing the flanging operation. Finally, the first cylinder 310 is controlled to run. The output end of the first cylinder 310 pushes the push rod 309 laterally towards the lower mold 202. With the assistance of multiple push bars 301 corresponding to the limit plates 307, the push rod 309 simultaneously pushes multiple push bars 301 to move. The push bars 301 push the inclined surface of the ejector rod 302 from the inclined groove to the horizontal plane. During this process, several ejector rods 302... 2. Simultaneously moving upwards, the ejector rod 302 drives the limiting ring 306 to apply a compressive force to the second spring 305, causing it to deform. Then, the ejector rod 302 drives the rubber plate 304 to move upwards through the limiting circular plate 303. Several rubber plates 304 simultaneously apply an upward pushing force to the workpiece at the top of the lower mold 202, thus ejecting the workpiece. The first cylinder 310 is controlled to operate on the same principle as above, so that the inclined groove of the push bar 301 is located directly below the inclined surface of the ejector rod 302. At this time, under the action of the second spring 305, a downward pushing force is applied to the limiting ring 306, so that the inclined surface of the ejector rod 302 contacts the corresponding inclined groove of the push bar 301. At this time, the rubber plate 304 and the inner surface of the lower mold 202 are at the same level, preparing for subsequent ejection.
