[0001] The invention relates to the technical field of drilling equipment, in particular to a plate drilling equipment for processing an injection mold of a vehicle armrest box. Background Art

[0002] With the diversification and personalization of automobile design, the structure and shape of vehicle armrest boxes are becoming increasingly complex, which puts higher requirements on the design and processing accuracy of injection molds. Traditional mold processing technology has problems such as insufficient processing accuracy and low processing efficiency when dealing with molds with complex shapes, and it is difficult to meet the rapidly changing market demand. At the same time, in order to improve the production efficiency of armrest boxes and reduce costs, it is necessary to develop more efficient and precise injection mold processing technology to achieve rapid manufacturing and mass production of molds. In addition, the deepening of environmental protection and sustainable development concepts in the automotive industry has also prompted injection mold processing to adopt more environmentally friendly materials and processes to reduce the impact on the environment.

[0003] When existing drilling equipment is used to process plates, the plates are prone to shift during the drilling process, resulting in poor drilling accuracy. At the same time, during the loading process, the plates shift on the transmission belt due to the influence of drilling vibration, resulting in a deviation between the loaded plates and the drilling position. Summary of the invention

The motor is connected to an external power supply to work, and the motor drives the rotating drum to rotate, and the rotating drum drives the transmission belt and the plate on the top of the transmission belt to move. With the movement of the transmission belt, the plate contacts and squeezes the contact plates on both sides, and the elastic performance of the reset spring is used to make the plate located in the middle of the top of the transmission belt. The flexible contact is used to laterally constrain the plate to prevent serpentine offset or position deviation during transportation, ensure that the plate is always aligned with the drilling station, and improve processing accuracy and consistency. The output end of the motor is fixedly connected to the rotating drum. There are several rotating drums, and several rotating drums are evenly arranged on the positioning plate.

At the same time, the motor is connected to an external power supply to work, and the motor drives the connecting block to rotate, so that the connecting block drives the drill bit to rotate. As the slider continues to move downward, the limit frame is forced to move, so that the drill bit drills the plate through the stepped hole, and the iron chips move upward along the spiral groove to avoid chips from accumulating in the processing area, thereby improving the processing efficiency and reducing secondary cutting and tool wear caused by chip accumulation. The inside of the circular ring, from the gap between the two semicircular rings to the outside, when the drill bit continues to move downward, the semicircular ring is located inside the stepped hole, and the blade cuts off the iron chips, which can quickly and accurately separate the iron chips from the workpiece. The top of the fixed block is fixedly connected to the driving motor, and the output end of the driving motor passes through the fixed block and extends to the inside of the fixed block. The output end of the driving motor is fixedly connected to the screw, and a slider is provided on the outside of the screw.

The outer side of the support plate is fixedly connected to a connecting seat, and the outer side of the connecting seat is rotatably connected to a connecting piece. The plate moves to the fixing assembly along with the transmission belt. At this time, the electric push rod works, so that the electric push rod pushes the square plate on the round rod to move in the direction of the vertical plate. At this time, the square plate drives the extension plate and the limit plate to move, so that the square plate and the extension plate are tightly fitted with the side corners of the plate. At the same time, the side edges of the limit plate contact and squeeze the two ends of the plate, so that the plate is located in the middle of the top of the support plate, and the plate is fixed by the square plates on both sides to avoid excessive drilling.

Under the action of the friction force, the roller rotates, and the rolling friction is used to replace the sliding friction, so as to reduce the friction between the plate and the equipment, thereby extending the extrusion between the rod and the side plate, and the compression spring is compressed by the force so that the side plate laterally constrains the plate to ensure that the plate completes the final position calibration before entering the drilling station, compensates for the slight deviation in the operation of the conveyor belt, and avoids drilling errors caused by position offset. The roller is fixedly connected to the rotating rod, and the rollers on both sides are slidably connected to the rotating rod.

The inclined force achieves flexible contact through force decomposition, reduces scratches on the surface of the plate, and can also avoid local stress concentration caused by unilateral limitation.

[0018] 3. The plate drilling equipment processed by the injection mold of the armrest box of the vehicle moves the iron chips upward along the spiral groove to avoid the accumulation of chips in the processing area, thereby improving the processing efficiency and reducing the secondary cutting and tool wear caused by chip accumulation.

[0019] 4. The panel drilling equipment processed by the injection mold of the vehicle armrest box generates extrusion between the extension rod and the side panel. The compression spring is compressed by force, so that the side panel laterally constrains the panel, ensuring that the panel completes the final position calibration before entering the drilling station, compensating for slight deviations in the operation of the conveyor belt, and avoiding drilling errors caused by position offset.

[0044] The plate moves to the fixed component 4 along with the transmission belt 24. At this time, the electric push rod 44 works, so that the electric push rod 44 pushes the square plate 47 to move on the round rod 45 toward the vertical plate 46. At this time, the square plate 47 drives the extension plate 48 and the limit plate 49 to move, so that the square plate 47 and the extension plate 48 are tightly fitted with the side corners of the plate. At the same time, the side of the limit plate 49 contacts and squeezes the two ends of the plate, so that the plate is located in the middle of the top of the support plate 41.

[0045] After the plate is fixed, the drive motor 55 is connected to an external power supply and works. The drive motor 55 drives the screw 54 to rotate, so that the screw 54 drives the slider 56 to move downward, so that the bottom of the limit frame 58 contacts the top of the plate. At the same time, the motor 57 is connected to an external power supply and works.
