Description

Technical Field

[0001] This utility model relates to the technical field of drawing forming mold equipment, specifically a drawing forming mold for an automobile seat bracket. Background Technology

[0002] When performing long-draw forming on automotive seat brackets, long-draw forming die equipment is often required. Utility model patent application CN202123259339.8 discloses a long-draw forming die for automotive body panels. By incorporating ball bearings, ventilation ducts, a dust extraction fan, and a dust collection box, the dust extraction fan is activated during the long-drawing process. The fan, through the micropores of the ball bearings, cleans dust and debris from the gap between the lower die and the pressure ring. Simultaneously, the ball bearings in the pressure ring increase the movement speed of the lower die within the pressure ring, thus improving the efficiency of long-drawing automotive body panels. According to the disclosed technical solution, existing long-draw forming die equipment has two main drawbacks. Firstly, when long-drawing automotive seat bracket materials, low temperatures can lead to insufficient material toughness, causing material breakage and compromising processing quality. Secondly, after heating to ensure the long-drawing of the automotive seat bracket, deformation can easily occur during cooling, further compromising processing quality.

[0003] Therefore, how to design a car seat bracket drawing die has become the problem we need to solve. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a drawing die for automobile seat brackets to solve the problems mentioned in the background. This utility model is reasonably designed, convenient to use, and suitable for drawing and forming automobile seat brackets.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a car seat bracket drawing forming mold, comprising a base and a movable plate, wherein a drawing assembly is mounted on the movable plate, the drawing assembly including a slide groove and a drawing die, a lifting assembly is mounted on the movable plate, the lifting assembly including a hydraulic cylinder and a piston, a forming assembly is mounted on the base, the forming assembly including a mold cavity and a heating plate, a pressing assembly is mounted on the movable plate, the pressing assembly including a motor and a lead screw, a pressure control assembly is mounted on the drawing die, the pressure control assembly including a threaded sleeve and a button, and a cooling assembly is mounted on the base, the cooling assembly including an air vent and a fan.

[0006] Furthermore, the hydraulic cylinders are welded to the top of the flap, distributed at the four corners of the flap, the top of the piston is locked on the inner wall of the top of the hydraulic cylinder, and the bottom of the piston passes through the flap via a sealing ring and is welded to the top of the base.

[0007] Furthermore, the mold cavity is opened on the inner side of the base, the slide groove is opened on the inner side of the flap, the two sides of the extension die are stuck on the inner wall of the slide groove, the extension die is located at the top of the mold cavity, the extension die is an automotive seat bracket drawing die, and the mold cavity is an automotive seat bracket forming mold cavity.

[0008] Furthermore, the motor is bolted to the top of the movable plate, a slot is provided on the inner side of the die, the outer side of the thread sleeve is clamped on the inner wall of the slot, and the top of the thread sleeve passes through the slot and extends to the top of the die.

[0009] Furthermore, the top end of the lead screw is keyed to the output shaft of the motor, and the bottom end of the lead screw passes through the flap and the threaded sleeve in sequence and extends to the bottom of the slot. The threaded sleeve is threaded onto the outer side of the lead screw.

[0010] Furthermore, the bottom of the threaded sleeve is connected to the inner wall of the slot via a spring, and the button is welded to the inner wall of the slot, with the button located at the bottom of the threaded sleeve.

[0011] Furthermore, the air vent is located on the inner side of the base, and an air duct is provided on the inner side of the base. Both ends of the air duct are connected to the air vent.

[0013] Beneficial effects: 1. When using this car seat bracket drawing die, the material is placed on top of the base, and the hydraulic cylinder is connected to an external hydraulic device. Hydraulic oil is pumped into the lower hydraulic cylinder through the hydraulic device, causing the hydraulic oil to push the movable plate downwards. This causes the movable plate to clamp the material at the top of the die cavity. Then, the motor is turned on, and the motor pushes the threaded sleeve downwards through the lead screw. The threaded sleeve pushes the die downwards through the spring. The die stretches and deforms the material downwards inside the die cavity until the material is shaped and the gap between the die cavity and the die is consistent. The threaded sleeve is pushed by the lead screw to compress the spring and press the button, stopping the motor. This avoids continuous motor operation that could damage the equipment or cause excessive pressure on the car seat bracket, thus effectively ensuring the safety of the equipment and the forming quality of the car seat bracket. If the temperature is low, the heating plate is turned on to heat the material, improving its toughness and preventing breakage during the drawing process, thus ensuring the processing quality of the car seat bracket.

The fan draws in air through the air vent on the right side of the base, and then through the air duct to the air vent on the left side of the base, and then flows outward. The airflow is used to cool down the car seat bracket being processed in the mold cavity. This allows the car seat bracket to be cooled down under the constraints of the mold cavity and the die, thereby eliminating the internal stress of the car seat bracket and preventing deformation of the car seat bracket after demolding, thus ensuring the processing quality of the car seat bracket.

[0015] 3. The car seat bracket drawing die is reasonably designed, efficient and convenient to use, and suitable for drawing and forming of car seat brackets. Attached Figure Description

A pressure control assembly is installed on the drawing die 4, the pressure control assembly including a threaded sleeve 11 and a button 12. A cooling assembly is installed on the base 1, the cooling assembly including an air vent 14 and a fan 16. The air vent 14 is opened on the inner side of the base 1, and an air duct 15 is opened on the inner side of the base 1. Both ends of the air duct 15 are connected to the air vent 14. At the bottom of the mold cavity 5, the blower 16 is bolted to the inside of the air vent 14. The heating plates are welded to the top of the mold cavity 5 and the bottom of the die 4. A switch assembly is externally connected to the base 1. The switch assembly is connected to the button 12, the heating plate 13 and the blower 16 via wires. The button 12 is connected to the motor 8 via wires. When the heating and drawing process is performed, when the blower 16 is turned on, the blower 16 draws in air through the air vent 14 on the right side of the base 1 and passes it through the air duct 15 to the air vent 14 on the left side of the base 1, and then flows outward. The airflow is used to cool the car seat bracket being processed in the mold cavity 5, so that the car seat bracket is cooled under the limitation of the mold cavity 5 and the die 4, thereby eliminating the internal stress of the car seat bracket and preventing the car seat bracket from deforming after demolding, thus ensuring the processing quality of the car seat bracket.

[0022] In this embodiment, the hydraulic cylinder 6 is welded to the top of the movable plate 2, and the hydraulic cylinders 6 are distributed at the four corners of the movable plate 2. The top end of the piston 7 is stuck on the inner wall of the top end of the hydraulic cylinder 6, and the bottom end of the piston 7 passes through the movable plate 2 through a sealing ring and is welded to the top of the base 1. The mold cavity 5 is opened on the inner side of the base 1, the slide groove 3 is opened on the inner side of the movable plate 2, and the two sides of the drawing die 4 are stuck on the inner wall of the slide groove 3. The drawing die 4 is located at the top of the mold cavity 5. The drawing die 4 is a drawing die for an automotive seat bracket, and the mold cavity 5 is a forming mold cavity for an automotive seat bracket. The motor 8 is bolted to the top of the movable plate 2. A slot 10 is formed on the inner side of the die 4. The outer side of the threaded sleeve 11 is engaged with the inner wall of the slot 10. The top of the threaded sleeve 11 passes through the slot 10 and extends to the top of the die 4. The top of the lead screw 9 is keyed to the output shaft of the motor 8. The bottom end of the lead screw 9 passes through the movable plate 2 and the threaded sleeve 11 sequentially and extends to the bottom of the slot 10. The threaded sleeve 11 is threaded onto the outer side of the lead screw 9. The bottom of the threaded sleeve 11 is connected to the inner wall of the slot 10 via a spring 17. The button 12 is welded to the inner wall of the slot 10. The button 12 is located at the bottom of the threaded sleeve 11. In use, the material is placed on the top of the base 1, and the hydraulic cylinder 6 is connected to an external hydraulic device. Hydraulic oil is pumped into the hydraulic cylinder 6 through the hydraulic device, causing the hydraulic oil to push the movable plate 2 downward, thereby causing the movable plate 2 to clamp the material at the top of the mold cavity 5. Then, the motor 8 is turned on, and the motor 8 pushes the threaded sleeve 11 downward through the lead screw 9. The threaded sleeve 11 pushes the die 4 downward through the spring 17. The die 4 stretches and deforms the material downward inside the mold cavity 5 until the material is shaped. The material is drawn and formed to match the gap between the mold cavity 5 and the die 4. The thread sleeve 11 is pushed by the lead screw 9 to compress the spring 17 and press the button 12, and the motor 8 stops working. This prevents the motor 8 from working continuously and causing equipment damage or excessive pressure on the car seat bracket, thus effectively ensuring the working safety of the equipment and ensuring the forming quality of the car seat bracket. If the temperature is low, the heating plate 13 is turned on to heat the material, improve the toughness of the material, and prevent the material from breaking during the drawing process, thus ensuring the processing quality of the car seat bracket.

[0023] This automotive seat bracket drawing die provides power to all electrical equipment via an external power source. During operation, the material is placed on top of the base 1, and the hydraulic cylinder 6 is connected to an external hydraulic device. Hydraulic oil is pumped into the hydraulic cylinder 6 through the hydraulic device, causing the hydraulic oil to push the flapper 2 downwards. This causes the flapper 2 to clamp the material at the top of the mold cavity 5. Then, the motor 8 is turned on. The motor 8 pushes the threaded sleeve 11 downwards via the lead screw 9. The threaded sleeve 11 pushes the die 4 downwards via the spring 17. The die 4 draws and deforms the material downwards inside the mold cavity 5 until the material is shaped and the gap between the mold cavity 5 and the die 4 is aligned. Under the push of the lead screw 9, the threaded sleeve 11 compresses the spring 17 and presses the button 12, stopping the motor 8. This prevents continuous operation of the motor 8 from damaging the equipment or causing excessive pressure on the automotive seat bracket. This effectively ensures the safe operation of the equipment and the molding quality of the car seat bracket. If the temperature is low, the heating plate 13 is turned on to heat the material, improve its toughness, and prevent the material from breaking during the drawing process, thus ensuring the processing quality of the car seat bracket. When the heating process is combined with the drawing process, the fan 16 is turned on. The fan 16 draws in air through the air vent 14 on the right side of the base 1 and passes it through the air duct 15 to the air vent 14 on the left side of the base 1, and then flows outward. The airflow is used to cool down the car seat bracket being processed in the mold cavity 5, so that the car seat bracket is cooled down under the limitation of the mold cavity 5 and the die 4, thereby eliminating the internal stress of the car seat bracket and preventing the car seat bracket from deforming after demolding, thus ensuring the processing quality of the car seat bracket.
