Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts production, and in particular to an automobile tailgate bracket manufacturing device and a manufacturing process thereof. Background Art

[0002] In the automotive manufacturing industry, tailgate brackets are key components of the tailgate structure. Their performance and quality play an important role in the overall safety and functionality of the vehicle. Typically made of high-strength aluminum alloy or steel, tailgate brackets are responsible for supporting and connecting the tailgate, bearing the weight of the tailgate and the various forces generated during opening and closing, and providing a mounting location for tailgate accessories. They are crucial for ensuring the tightness and safety of the tailgate. Stamping is a common process in their production and processing. For example, in the prior art, the automobile bracket stamping equipment disclosed in the Chinese patent with the announcement number "CN222587908U" realizes the placement and fixation of the stamped parts through L-shaped blocks and T-shaped pressure plates. However, this device still has obvious defects in actual application. During the stamping and forming period, it relies on manual loading, unloading and demolding operations, which not only makes the loading and unloading processes cumbersome and consumes a lot of manpower, but also the manual operation takes a long time, which greatly increases the processing cost and makes it difficult to improve production efficiency. With the continuous improvement of the automobile manufacturing industry's requirements for production efficiency and cost control, there is an urgent need to improve the design of the existing automobile tailgate bracket stamping and forming equipment to meet the development needs of the industry.

The outer surface of the connecting plate is sleeved with a sleeve frame, and the upper end of the sleeve frame is rotatably connected to the outer end of the rotating shaft. The bottom of the base plate is rotatably connected to a linkage rod, and the end of the linkage rod is rotatably connected to the outer side of the feeding mechanism.

[0008] Furthermore, the loading mechanism includes a rail frame and a loading platform, the loading platform is fixedly installed in the middle of the top rear side of the base plate, the rail frame is fixedly installed at the lower end of the back side of the base frame away from the demolding mechanism, the interior of the rail frame is slidably connected to a movable block, the outer side of the movable block is rotatably connected to the lower end of the linkage rod, the side of the movable block away from the linkage rod is fixedly connected to a fixed plate, the front side of the fixed plate is fixedly installed with a connecting shaft, and the front end of the connecting shaft is fixedly installed with a push plate.

[0009] Furthermore, a bearing plate is fixedly installed on the top of the loading platform, and balls are rotatably connected to the top of the bearing plate at equal intervals.

[0012] Furthermore, the cross-sectional shape of the inner cavity of the bottom rail and the side shape of the slider are both set to be convex, and the outer corners of the base frame, connecting arm, stamping platform and base are all set to be arc-shaped.

[0013] Step 1: Equipment startup and stamping preparation. Start the hydraulic cylinder. The hydraulic cylinder generates thrust to push the sleeve frame downward. The sleeve frame drives the connecting plate to drive the base plate to rotate. The base plate rotates and pulls the connecting plate to move. At the same time, it drives the linkage rod to move the movable block outward, pulling the fixed plate, the connecting shaft and the push plate backward. At the same time, the hydraulic cylinder drives the die base downward, pushing the upper die downward. The upper and lower dies squeeze each other to complete the extrusion molding of the product. The push plate moves to the back of the carrier plate. At this time, the blank material to be stamped is placed on the top back area of the carrier plate. Step 2: Stamping and forming: keep the hydraulic cylinder in working state to make the upper mold and the lower mold continue to squeeze to ensure that the product between the two is stamped and formed; Step 3: After the stamping is completed and the material is ready for loading, the hydraulic cylinder is started to move upward, and the hydraulic cylinder drives the die base to move upward. The die base drives the upper die to rise, and the upper die and the lower die are gradually separated. The fixed shaft rises as the upper die moves upward, driving the sleeve frame at the outer end of the rotating shaft to move. The sleeve frame slides on the connecting plate, driving the base plate to rotate on the fixed plate. The rotation of the base plate causes the movable block inside the rail frame to slide through the linkage rod, pulling the fixed plate and the connecting shaft to move, pushing the plate toward the lower die; Step 4: Automatic loading, the hydraulic cylinder runs, prompting the linkage mechanism to drive the movable block to slide and drive the push plate to accurately push the blank material on the carrying plate onto the lower mold, completing the automatic loading process; Step 5: Automatic unloading and demoulding. When the hydraulic cylinder drives the die base and the upper die to move upward, the linkage mechanism drives the movable block to push the fixed plate, so that the push plate at the end of the coupling moves forward, pushing the blank material on the loading platform forward; the upward movement of the die base drives the connecting arm to rise, and the connecting arm drives the demoulding top plate to move upward. The demoulding top plate drives the demoulding ejector rod to rise, and the demoulding ejector rod squeezes the formed bracket inside the lower die and pushes it out of the die; the movable block drives the push plate to move forward, and the push plate pushes the unformed blank onto the lower die. The unformed blank pushes the formed bracket into the unloading guide plate, and the formed bracket is guided to the discharge device along the unloading guide plate; Step 6: Blank correction. After completing the loading operation, start the drive motor to drive the screw to rotate. The threads at both ends of the screw rotate in opposite directions. The drive slider drives the fixed arms to move closer or farther away from each other. The fixed arms drive the correction splint to clamp the unformed blank placed on the top of the lower mold, correct its position, and place the blank accurately in the center of the top of the lower mold.

[0014] Beneficial effects of the present invention: 1. This device realizes the automatic loading function through the cooperation of the stamping mechanism and the linkage mechanism. After the hydraulic cylinder is started, the linkage of a series of components enables the push plate to automatically move backward during stamping and forming, leaving the carrier plate for placing the blank material; when the hydraulic cylinder moves up and resets after forming, it can automatically feed the material on the carrier plate into the mold. The entire process does not require frequent manual loading operations, effectively reducing manpower input and avoiding the problems of low efficiency and operational errors that may occur in manual loading. It significantly improves the convenience of equipment use and makes the production process smoother and more efficient. 2. This device uses a linkage mechanism, a loading mechanism, and a demoulding mechanism to cooperate with each other to realize the automatic unloading function. During use, when the hydraulic cylinder drives the mold base and the upper mold to move upward, the push plate pushes the material on the loading table forward. At the same time, the demoulding ejector pushes the formed bracket out of the mold, and the unformed blank pushes the formed bracket into the unloading guide plate for discharge. The automatic unloading function effectively reduces the processing time after the product is formed, avoids the tediousness and delay of manual unloading, connects the production links closely, optimizes the overall production process, and further improves production efficiency. 3. The automatic loading and unloading of this equipment are controlled by hydraulic cylinders, eliminating the need for complex and expensive electrical intelligent control structures. This design significantly reduces the initial manufacturing cost of the equipment, simplifies the equipment maintenance process, and reduces subsequent maintenance costs. While ensuring automated production functions, it achieves efficient processing at a lower cost, significantly enhancing the economic practicality of the equipment. 4. During use, after the loading is completed, the drive motor drives the screw to rotate, and the opposite thread rotation directions at both ends of the screw are used to make the slider drive the fixed arm to move, and then drive the correction splint to clamp and correct the unformed blank on the top of the lower mold to ensure that the blank is placed in the center. This precise correction function effectively avoids molding defects caused by blank position deviation, reduces the production of defective products, improves the molding accuracy and stability of the product, improves the success rate of production and processing, ensures product quality, and enhances the market competitiveness of the company's products.

A hydraulic cylinder 52 is fixedly mounted on the top of the top seat 51. The bottom output end of the hydraulic cylinder 52 passes through the top seat 51 and is fixedly mounted with a die base 53. The bottom of the die base 53 is fixedly connected to an upper die 54. One side of the die base 53 is rotatably connected to the linkage mechanism 6. The demoulding mechanism 8 is fixedly mounted on the side of the die base 53 away from the linkage mechanism 6. When the automobile tailgate bracket manufacturing device is working, the hydraulic cylinder 52 in the stamping mechanism 5 is started. The hydraulic cylinder 52 is mounted on the top seat 51 on the top of the base frame 4, and its output end pushes the die base 53 and the upper die 54 connected thereto to move downward, squeezing the lower die 10 in the middle of the top of the stamping table 3 to achieve stamping of the tailgate bracket; the feeding mechanism 7 is mounted in the middle of the rear side of the stamping table 3. When the hydraulic cylinder 52 drives the die base 53 to move downward for stamping, the linkage mechanism 6 connected thereto is triggered, and the linkage mechanism 6 drives the feeding mechanism 7 to move , the pushing plate 76 is moved to the rear side of the carrying plate 77 to place the blank material to be processed; after forming is completed, the hydraulic cylinder 52 drives the die base 53 and the upper die 54 to move upward, the upper die 54 and the lower die 10 are separated, and the linkage mechanism 6 is activated again, driving the loading mechanism 7 to push the blank material on the carrying plate 77 onto the lower die 10 to complete automatic loading; at the same time, the demoulding mechanism 8 fixedly mounted on the side of the die base 53 away from the linkage mechanism 6 is driven as the die base 53 moves upward, and the demoulding end of the demoulding mechanism 8 passes through the lower die 10, pushing out the formed tailgate bracket; finally, the correction mechanism 9 at the front end of the bottom of the stamping table 3 drives the screw rod 93 to rotate through the driving motor 92, and uses the opposite threads at both ends of the screw rod 93 to drive the slider 94 to drive the fixed arm 95 to move, thereby causing the correction clamp 96 to clamp and correct the unformed blank on the top of the lower die 10 to ensure that the blank is accurately placed in the center in preparation for the next stamping forming.

[0019] Combine Figure 1-Figure 3 As shown, a blanking guide plate 55 is fixedly installed at the middle of the front end of the punching table 3, and the blanking guide plate 55 is arranged to be inclined as a whole.

[0020] According to the technical solution in the above-mentioned embodiment of the present application, during the operation of the automobile tailgate bracket manufacturing device, after the demoulding mechanism 8 pushes out the tailgate bracket formed in the lower mold 10, the pushing plate 76 of the loading mechanism 7 will push the unformed blank onto the lower mold 10. During the movement, the unformed blank will push the formed bracket toward the unloading guide 55 which is tiltedly set at the middle part of the front end of the stamping table 3. Due to the inclined structure of the unloading guide 55, the formed tailgate bracket will automatically slide down along the inclined surface of the unloading guide 55 under the action of gravity, thereby being smoothly discharged from the device, realizing the automatic collection and transportation of the formed products, reducing manual intervention, and improving production efficiency. At the same time, it also avoids the accumulation of formed products on the surface of the stamping table 3 and affecting subsequent processing operations. Example 2

[0021] Combine Figures 1-6 As shown, the linkage mechanism 6 includes a fixed shaft 61 and a linkage assembly 62. The fixed shaft 61 is fixedly installed on the upper end of the side of the mold base 53 away from the demolding mechanism 8. The linkage assembly 62 is rotatably connected to the side of the base frame 4 close to the fixed shaft 61. The outer side of the fixed shaft 61 is rotatably connected with the rotating shaft 63. The linkage assembly 62 is fixedly installed on the outer end of the rotating shaft 63. The lower end of the linkage assembly 62 is transmission connected to the feeding mechanism 7. The linkage assembly 62 includes a fixed plate 621. The fixed plate 621 is fixedly installed on the middle part of the side of the base frame 4 away from the demolding mechanism 8. The outer side of the fixed plate 621 is rotatably connected with a base plate 622. The upper end of the base plate 622 is fixedly installed with a connecting plate 623. The outer surface of the connecting plate 623 is sleeved with a sleeve frame 624. The upper end of the sleeve frame 624 is rotatably connected to the outer end of the rotating shaft 63. The bottom of the base plate 622 is rotatably connected to a linkage rod 625. The end of the linkage rod 625 is rotatably connected to the outer side of the feeding mechanism 7.

[0022] According to the technical solution in the embodiment of the present application, during the use of the device, when the linkage mechanism 6 is working, when the die base 53 of the stamping mechanism 5 moves up and down under the drive of the hydraulic cylinder 52, the fixed shaft 61 fixedly installed on the upper end of the die base 53 away from the demolding mechanism 8 moves accordingly, and the movement of the fixed shaft 61 drives the rotating shaft 63 connected to the outer side to move, and the linkage component 62 at the outer end of the rotating shaft 63 is driven. In the linkage component 62, the fixed disk 621 is fixed on the base frame 4, and the base plate 622 can rotate around the fixed disk 621. The sleeve frame 624 connected to the outer end of the rotating shaft 63 is sleeved on the outer surface of the connecting plate 623, so that the sleeve frame 624 can drive the connecting plate 623 to move. When the sleeve frame 624 moves with the rotating shaft 63, it will pull the connecting plate 623, and then drive the base plate 622 to rotate outside the fixed plate 621. During the rotation of the base plate 622, the linkage rod 625 connected to its bottom rotationally swings accordingly, and the end of the linkage rod 625 is connected to the outer side of the feeding mechanism 7 for rotation, thereby transmitting the motion to the feeding mechanism 7, realizing the transmission of the two. In this way, the up and down movement of the mold base 53 can accurately drive the feeding mechanism 7 to perform corresponding actions through the fixed shaft 61, the rotating shaft 63, and the linkage assembly 62, completing a series of processes such as loading and unloading. The overall loading processing adopts a linkage design, relying on the hydraulic cylinder 52 for auxiliary drive, and the overall cost is relatively low.

[0023] Combine Figure 5-Figure 6As shown, the loading mechanism 7 includes a rail frame 71 and a loading platform 72. The loading platform 72 is fixedly installed in the middle of the top rear side of the base plate 622. The rail frame 71 is fixedly installed at the lower end of the back side of the base frame 4 away from the demolding mechanism 8. The inside of the rail frame 71 is slidably connected with a movable block 73. The outer side of the movable block 73 is rotatably connected to the lower end of the linkage rod 625. The side of the movable block 73 away from the linkage rod 625 is fixedly connected with a fixed plate 74. The front side of the fixed plate 74 is fixedly installed with a connecting shaft 75. The front end of the connecting shaft 75 is fixedly installed with a pushing plate 76. The top of the loading platform 72 is fixedly installed with a supporting plate 77. The top of the supporting plate 77 is rotatably connected with balls 78 at equal intervals.

[0024] The technical solution in the embodiment of the present application is that the operation of the feeding mechanism 7 depends on the drive of the linkage mechanism 6. When the linkage rod 625 in the linkage mechanism 6 swings, its lower end is connected to the movable block 73 inside the rail frame 71, which drives the movable block 73 to slide in the rail frame 71. When the movable block 73 slides, the fixed plate 74 fixedly connected thereto moves accordingly, thereby driving the connecting shaft 75 on the front side of the fixed plate 74 and the pushing plate 76 at the front end of the connecting shaft 75 to move. When the stamping mechanism 5 moves downward for stamping, the linkage rod 625 drives the movable block 73, the fixed plate 74, the connecting shaft 75 and the pushing plate 76 at the front end of the connecting shaft 75. The push plate 76 moves backward and moves to the rear side of the supporting plate 77. At this time, the operator can place the blank material on the supporting plate 77. The balls 78 connected to the top of the supporting plate 77 are rotated at equal intervals to reduce the friction when the material is placed and moved, making the operation convenient. After the stamping is completed, the stamping mechanism 5 moves upward, and the linkage rod 625 moves again, driving the movable block 73 to slide forward, and the push plate 76 moves forward accordingly, pushing the blank material on the supporting plate 77 to the lower mold 10, completing the automatic loading process, and achieving close coordination and efficient connection with the stamping process. Example 3

[0025] Combine Figure 2-Figure 6As shown, the demoulding mechanism 8 includes a connecting arm 81 and a reserved groove 82. The connecting arm 81 is fixedly installed on the upper end of the mold base 53 away from the linkage mechanism 6. The reserved groove 82 is opened on the top side of the stamping table 3. The connecting arm 81 is slidably connected to the inside of the reserved groove 82. The bottom of the connecting arm 81 passes through the reserved groove 82 and is fixedly connected to the demoulding top plate 83. The four corners of the top of the demoulding top plate 83 are fixedly connected to the demoulding ejector rod 84. The end of the demoulding ejector rod 84 passes through the stamping table and the lower mold 10. The correction mechanism 9 includes a bottom rail 91. The bottom rail 91 is fixedly connected to the bottom front end of the stamping table 3. The bottom rail 9 1 is fixedly connected to one side of the drive motor 92, and the output end of the drive motor 92 passes through the bottom rail 91 and is fixedly installed with a screw rod 93. The threads at both ends of the screw rod 93 are rotated in opposite directions, and the outer surfaces of the screw rod 93 are both threadedly connected to sliders 94. The bottom of the slider 94 is fixedly connected to a fixed arm 95, and the overall shape of the fixed arm 95 is U-shaped. The inner end of the fixed arm 95 is fixedly connected to a correction splint 96. The cross-sectional shape of the internal cavity of the bottom rail 91 and the side shape of the slider 94 are both set to be convex, and the external edges and corners of the base frame 4, the connecting arm 81, the punching table 3 and the base 1 are all set to be arc-shaped.

[0026] According to the technical solution in the above-mentioned embodiment of the present application, the device can effectively ensure the quality and efficiency of the manufacturing of the automobile tailgate bracket by setting the demoulding mechanism 8 and the correction mechanism 9 to cooperate with each other. During the demoulding process during use, when the mold base 53 moves upward under the action of the hydraulic cylinder 52, the connecting arm 81 fixedly installed on the upper end of the mold base 53 away from the linkage mechanism 6 rises accordingly. Since the connecting arm 81 is slidably connected to the reserved groove 82 on the top of the stamping table 3, its upward movement drives the demoulding top plate 83 at the bottom to move upward synchronously, and the demoulding ejector rods 84 at the four corners of the top of the demoulding top plate 83 rise accordingly, passing through the stamping table 3 and the lower mold 10, and pushing the formed tailgate bracket out of the lower mold 10 to complete the demoulding operation. In the correction link, the drive motor 92 is installed On the side of the bottom rail 91 at the front end of the bottom of the stamping table 3, after starting the drive motor 92, its output end drives the screw 93 to rotate. Because the threads at both ends of the screw 93 rotate in opposite directions, the sliders 94 threaded at both ends of the outer surface move toward or in the opposite direction along the screw 93. The U-shaped fixed arm 95 fixed at the bottom of the slider 94 moves with the slider 94, driving the correction clamp 96 at the inner end to clamp and correct the unformed blank on the top of the lower mold 10, ensuring that the blank is placed in the center of the lower mold 10, thereby improving the accuracy of subsequent stamping and forming. In addition, the external corners of the base frame 4, connecting arm 81, stamping table 3 and base 1 are set to arc shapes, which effectively reduce the risk of collision and injury during operation, while reducing the possibility of material jamming, ensuring safe and smooth operation of the equipment.

[0027] Step 1: Equipment startup and stamping preparation, start the hydraulic cylinder 52, the hydraulic cylinder 52 generates thrust to push the sleeve frame 624 downward, the sleeve frame 624 drives the connecting plate 623 to drive the base plate 622 to rotate, the base plate 622 rotates and pulls the connecting plate 623 to move, and at the same time drives the linkage rod 625 to move the movable block 73 outward, pulling the fixed plate 74, the connecting shaft 75 and the pushing plate 76 backward; at the same time, the hydraulic cylinder 52 drives the die base 53 downward, pushing the upper die 54 downward, the upper die 54 and the lower die 10 squeeze each other, completing the extrusion molding of the product, and the pushing plate 76 moves to the rear side of the carrier plate 77. At this time, the stamped blank material is placed on the top rear area of the carrier plate 77; Step 2: Stamping and forming: keep the hydraulic cylinder 52 in working state to make the upper mold 54 and the lower mold 10 continue to squeeze, ensuring that the product located between the two is stamped and formed; Step 3: After the stamping is completed and the material loading is prepared, after the product is formed, the hydraulic cylinder 52 is started to move upward, and the hydraulic cylinder 52 drives the die base 53 to move upward. The die base 53 drives the upper die 54 to rise, and the upper die 54 and the lower die 10 are gradually separated. The fixed shaft 61 rises as the upper die 54 moves upward, driving the sleeve frame 624 at the outer end of the rotating shaft 63 to move. The sleeve frame 624 slides on the connecting plate 623, driving the base plate 622 to rotate on the fixed plate 621. The rotation of the base plate 622 causes the movable block 73 inside the rail frame 71 to slide through the linkage rod 625, pulling the fixed plate 74 and the connecting shaft 75 to move, and pushing the plate 76 to move toward the lower die 10; Step 4: Automatic loading, the hydraulic cylinder 52 operates, prompting the linkage mechanism 6 to drive the movable block 73 to slide and drive the push plate 76 to accurately push the blank material on the carrying plate 77 onto the lower mold 10, completing the automatic loading process; Step 5: Automatic unloading and demoulding. When the hydraulic cylinder 52 drives the die base 53 and the upper die 54 to move upward, the linkage mechanism 6 drives the movable block 73 to push the fixed plate 74, so that the push plate 76 at the end of the connecting shaft 75 moves forward, and the blank material on the loading platform 72 is pushed forward; the die base 53 moves upward to drive the connecting arm 81 to rise, and the connecting arm 81 drives the demoulding top plate 83 to move upward, and the demoulding top plate 83 drives the demoulding ejector rod 84 to rise, and the demoulding ejector rod 84 squeezes the bracket formed inside the lower die 10 and pushes it out of the die; the movable block 73 drives the push plate 76 to move forward, and the push plate 76 pushes the unformed blank onto the lower die 10, and the unformed blank pushes the formed bracket into the unloading guide plate 55, and the formed bracket is guided to the discharge device along the unloading guide plate 55; Step 6: Blank correction. After completing the loading operation, start the drive motor 92 to drive the screw 93 to rotate. The threads at both ends of the screw 93 rotate in opposite directions. The drive slider 94 drives the fixed arm 95 to move closer or farther away from each other. The fixed arm 95 drives the correction clamp 96 to clamp the unformed blank placed on the top of the lower mold 10, correct its position, and place the blank accurately in the center of the top of the lower mold 10.

[0028] The use principle and advantages of the present invention are as follows: the device can realize an efficient and orderly stamping operation process by setting the stamping mechanism 5. When the device is running, the hydraulic cylinder 52 is started, and the thrust generated by the hydraulic cylinder 52 pushes the sleeve frame 624 to move downward. During the downward movement of the sleeve frame 624, the connecting plate 623 is driven, and then the base plate 622 is driven to rotate. The sliding design between the sleeve frame 624 and the connecting plate 623 provides the necessary activity space for the rotation of the base plate 622, so that the movements of the various components do not interfere with each other. During the rotation process, the base plate 622 will pull the connecting plate 623 to generate corresponding activities, and at the same time drive the linkage rod 625 to move, prompting the movable block 73 to move toward the outside direction. The movement of the movable block 73 will pull the fixed plate 74, the connecting shaft 75 and the pushing plate 76 at the end of the connecting shaft 75 to move backward; At the same time, the operation of the hydraulic cylinder 52 also drives the die base 53 to move downward, and the downward movement of the die base 53 pushes the upper die 54 to move downward. The upper die 54 and the lower die 10 squeeze each other to extrude the product located therebetween. During the stamping and closing process, the push plate 76 just moves to the rear side of the carrier plate 77. At this time, the operator can place the blank material to be stamped on the rear side area of the top of the carrier plate 77. When the product is formed, the hydraulic cylinder 52 is started again to move it upward, and the hydraulic cylinder 52 drives the mold base 53 to move upward, and the mold base 53 drives the upper mold 54 to rise, and the upper mold 54 and the lower mold 10 are gradually separated. During this separation process, the fixed shaft 61 rises as the upper mold 54 moves upward, and the rise of the fixed shaft 61 drives the sleeve frame 624 at the outer end of the rotating shaft 63 to move. While the sleeve frame 624 slides on the connecting plate 623, it drives the base plate 622 to rotate on the fixed plate 621. The rotation of the base plate 622 transmits the motion through the linkage rod 625, causing the movable block 73 inside the rail frame 71 to slide. The sliding of the movable block 73 pulls the fixed plate 74 and the connecting shaft 75 to move, thereby pushing the pushing plate 76 to move in the direction of the lower mold 10, and accurately pushing the blank material on the carrying plate 77 onto the lower mold 10. It can be seen that when the hydraulic cylinder 52 moves down to complete the stamping and forming action, the device can automatically move the pushing plate 76 away, leaving the top of the carrying plate 77 free for placing new blank material; and in the process of the hydraulic cylinder 52 moving up and resetting, the blank material on the carrying plate 77 can be automatically fed to the top of the lower mold 10, realizing the automatic loading function, which can effectively improve the convenience of the device during use; In addition, the present device realizes an automated unloading process through the coordinated cooperation of the linkage mechanism 6, the feeding mechanism 7 and the demoulding mechanism 8. When the hydraulic cylinder 52 drives the mold base 53 and the upper mold 54 to move upward, the linkage mechanism 6 plays a role, driving the movable block 73 to push the fixed plate 74, thereby causing the pushing plate 76 at the end of the connecting shaft 75 to move forward. In the process of the pushing plate 76 moving forward, the blank material on the loading platform 72 is pushed forward. At the same time, the upward movement of the mold base 53 will drive the connecting arm 81 to rise. The rise of the connecting arm 81 drives the demoulding top plate 83 to move upward. The demoulding top plate 83 then drives the demoulding ejector rod 84 to rise, and the demoulding ejector rod 84 moves upward. After the lifting, the bracket formed inside the lower mold 10 is squeezed and the formed bracket is pushed out of the lower mold 10. In the process of the demoulding ejector 84 pushing the bracket to be demoulded, the movable block 73 drives the pushing plate 76 to move forward, and the pushing plate 76 pushes the unformed blank onto the lower mold 10. The unformed blank will push the formed bracket into the blanking guide 55. The formed bracket is guided to the discharge device along the blanking guide 55. In the design of this device, during the loading process, after the demoulding ejector 84 completely pushes out the formed bracket, the pushing plate 76 just pushes the unformed blank to contact the formed and completely demoulded bracket, which can ensure the stability of the pushing. During the use of this equipment, the entire automatic loading and unloading process is controlled by the hydraulic cylinder 52, and there is no need to configure a complex electrical intelligent control structure, which reduces the manufacturing cost of the device. After the loading operation is completed, the drive motor 92 is started to drive the screw rod 93 to rotate. Since the threads at both ends of the screw rod 93 rotate in opposite directions, the slider 94 will be driven to drive the fixed arms 95 to move closer or farther away from each other. In the process of the fixed arms 95 moving relative to each other, the correction splint 96 is driven to clamp the unformed blank placed on the top of the lower mold 10 and correct its position so that the blank can be accurately centered on the top of the lower mold 10. This precise correction operation helps to improve the efficiency and stability of compression molding, reduce the generation of defective products during the compression molding process, and effectively improve the success rate of production and processing.
