TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile, concretely relates to a hot-pressing reinforcing rib injection integrated forming die for automobile tail door. BACKGROUND

[0002] A car is a motor vehicle powered by an engine for transporting people and goods. It is usually powered by an internal combustion engine, an electric motor or a hybrid power system. Modern car design focuses on safety, fuel efficiency and environmental protection, while equipped with various intelligent technologies such as automatic driving, Internet of Vehicles, etc. Cars are widely used in daily travel, logistics transportation and various commercial fields, and are an indispensable important means of transportation in modern society.

[0003] After searching, the Chinese patent "A reinforcing rib forming die" with authorization announcement number "CN222242343U" is related to the technical field of reinforcing rib forming die, specifically a reinforcing rib forming die, which comprises: a machining table, the bottom of the machining table is provided with a supporting leg, the surface of the machining table is fixedly installed with a bending machine; a bending feeding mechanism is arranged on one side of the machining table for feeding when the reinforcing rib is bent and formed; wherein the bending feeding mechanism comprises a fixed frame fixedly installed on the surface of the machining table; when feeding and bending, the reinforcing rib can be stably positioned by the feeding assembly during bending, which facilitates stable bending. When the next bending is needed, the positioning can be quickly released, so that the reinforcing rib can move freely, thereby facilitating the movement of the reinforcing rib for the next bending, improving the smoothness of operation during multiple bending, and ensuring the accurate position and stability of the reinforcing rib during the whole bending process through the contact of the contact assembly with the reinforcing rib.

[0004] Although the above-mentioned reinforcing rib die sets the contact assembly to position the reinforcing rib during use, the height of the contact assembly is close to that of the feeding assembly. When the previous segment of the reinforcing rib is bent and the next segment is bent, the reinforcing rib segment after bending is lifted by the contact assembly. Therefore, during subsequent bending operation, the reinforcing rib is easily slightly bent horizontally due to being lifted by the contact assembly during longitudinal bending, thereby affecting the overall shape of the reinforcing rib, and the overall displacement of the reinforcing rib is caused due to uneven gravity, affecting the processing quality.

[0005] Based on this, the utility model designs a hot-pressing reinforcing rib injection integrated forming die for automobile tail door to solve the above-mentioned problems. UTILITY MODEL CONTENTS

[0031] In the embodiments of the utility model, the auxiliary assembly 6 further comprises a cylinder body 601 fixed above the connecting plate 3, a piston rod 602 is slidably connected in the cylinder body 601, the lower end of the piston rod 602 penetrates to the lower side of the connecting plate 3 and is fixedly connected with the pressing plate 5, through cooperation of the cylinder body 601 and the piston rod 602, the cylinder body 601 can adsorb external gas by cooperation of the air pipe and the suction cup 605 when the push rod 4 makes the pressing plate 5 displace downward and shapes the reinforcing rib, so that the suction cup 605 has adsorption force.

[0032] In specific use, first, the staff places the reinforcing rib on the bearing plate 9, at this time, the reinforcing rib is in contact with the pulley 10, then the push rod 4 can be opened and the pressing plate 5 is displaced downward, the pressing plate 5 presses the reinforcing rib downward, because the second spring 13 is arranged in the shell 12 below the pulley 10, the second spring 13 will contract when the reinforcing rib is pressed downward, the pulley 10 will be pressed and displaced downward, because the piston rod 602 will displace downward in the cylinder body 601 when the push rod 4 pushes the pressing plate 5 to move to the reinforcing rib, at this time, the space in the cylinder body 601 above the piston rod 602 will continuously intake air, which also means that the suction cup 605 continuously adsorbs external gas, so that the suction cup 605 has adsorption force, when the lower side of the reinforcing rib will be in contact with the suction cup 605, the suction cup 605 will adsorb the reinforcing rib, when the pressing plate 5 presses and shapes the reinforcing rib, the reinforcing rib will be bent along the angle of the two bearing plates 9, at this time, the suction cup 605 adsorbed on the surface of the reinforcing rib will slide on the first guide rail 603 along with the bending of the reinforcing rib, which can prevent the reinforcing rib from deviating in position when being shaped.

[0033] It should be noted that the air pipe between the cylinder body 601 and the suction cup 605 is a corrugated pipe and has a certain plasticity, and when the reinforcing rib is shaped, the edge may be raised, therefore, only before shaping the reinforcing rib, the staff needs to move the air pipe to both sides according to the width of the reinforcing rib and ensure that the length is greater than the width of the reinforcing rib, so as to prevent the air pipe from being damaged;

[0034] In the embodiment of the utility model, the upper portion of the cylinder body 601 is provided with two air holes, the air holes of the cylinder body 601 are communicated with an air pipe, the air pipe of the cylinder body 601 is a multi-way pipe, one end of the air pipe of the cylinder body 601 penetrates into the sliding seat 604 and is communicated with the suction cup 605;

[0037] When the staff shapes one segment of the reinforcing rib, the push rod 4 drives the pressing plate 5 to rise, at this time, the piston rod 602 pushes the gas in the cylinder body 601 outwards, the inside of the suction cup 605 is under positive pressure and no longer has the adsorption force, and the second spring 13 is no longer extruded, at this time, the pulley 10 is bounced up by the second spring 13, the reinforcing rib is lifted upwards, and then the staff can push the shaped segment of the reinforcing rib forward and perform the next shaping operation, when the reinforcing rib is pushed, the rotating direction of the pulley 10 is consistent with the moving path of the reinforcing rib, therefore, the pulley 10 can provide the auxiliary moving effect for the reinforcing rib and can improve the smoothness of the reinforcing rib during the movement;
