Description

Technical Field

[0001] The utility model belongs to the technical field of bumper injection molding, and particularly relates to a bumper injection molding gate processing device. Background Art

[0002] The bumper is a key safety accessory on the car. It is located at the front and rear ends of the vehicle. Its main function is to absorb and disperse the impact force during a collision, thereby protecting the body structure of the car and to a certain extent protecting the safety of pedestrians. The bumper is usually made of plastic or metal and is tightly integrated with the body. The bumper injection molding gate processing device is a special tool or machine component used to remove the gate (i.e. injection molding port) of the bumper parts after injection molding during the bumper production process. This device can ensure the quality of the finished bumper, remove excess plastic parts, and improve the appearance flatness of the product.

[0003] In the existing bumper injection molding gate processing device, when the shear knife is worn and needs to be replaced, it uses bolts to fix the shear knife, so that personnel need to manually loosen and tighten the bolts. The process of replacing the shear knife is cumbersome and time-consuming. Repeated disassembly of the bolts may cause thread wear or loosening of the bolts, thereby affecting the stability and shearing effect of the shear knife. After long-term use, the shear knife fixed with bolts may be displaced, affecting the shearing accuracy and increasing the defective rate. Utility Model Content

[0005] In order to solve the above technical problems, the technical scheme adopted by the utility model is: a bumper injection molding gate processing device, comprising a processing table, four suction cups are arranged on the upper end of the processing table, a slide rail is arranged on the rear side of the upper end of the processing table, a sliding frame is arranged for sliding inside the slide rail, a sliding block is arranged for sliding inside the sliding frame, an electric push rod 1 is arranged at the lower end of the sliding block, a connecting plate is arranged on the telescopic end of the electric push rod 1, an electric push rod 2 is arranged on the left and right sides of the connecting plate, a sliding frame is arranged on the telescopic end of the electric push rod 2, a shearing knife is slidably arranged inside the sliding frame, a left and right moving mechanism is arranged inside the slide rail, a front and rear moving mechanism is arranged inside the sliding frame, a quick assembly and disassembly mechanism is arranged on the front side faces of the two sliding frames, the left and right moving mechanism comprises a screw rod 1 arranged inside the slide rail, the sliding frame is threadedly connected to the screw rod 1, an electric push rod 2 is arranged on the left side of the slide rail Machine one, the output shaft of motor one is connected with the left side of screw rod one through a coupling, the front-back moving mechanism includes screw rod two arranged inside the sliding frame, the sliding block is threadedly connected with screw rod two, the rear side of the sliding frame is provided with motor two, the output shaft of motor two is connected with the rear side of screw rod two through a coupling, the quick assembly and disassembly mechanism includes frame plates respectively arranged on the front side surfaces of the two sliding frames, locking columns are slidably arranged inside the two frame plates, locking holes are provided on the front side surfaces of the two shearing knives, the two locking columns respectively pass through the through holes provided on the sliding frame and are plugged into adjacent locking holes, limit disks are provided on the outer arc surfaces of the two locking columns, springs are provided between the limit disk and the frame plate, the two springs are respectively sleeved on the outer arc surfaces of the corresponding locking columns, and auxiliary pulling components are provided at the lower ends of the two locking columns, and the auxiliary pulling components include pull disks arranged at the lower ends of the two locking columns.

[0006] As a further improvement of the utility model, a control panel is arranged on the front side of the processing table, and the motor 1, the motor 2, the suction cup, the electric push rod 1 and the electric push rod 2 are all electrically connected to the control panel.

[0007] As a further improvement of the utility model, a support frame is provided at the lower end of the processing table, a collection box is provided inside the support frame, two material drop openings are provided at the upper end of the processing table, and four support legs are provided at the lower end of the support frame.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] Firstly, the bumper after injection molding is placed on the suction cup, and then the suction cup is controlled to be opened to fix the bumper. Then, the electric push rod 1 is controlled to be opened, and the telescopic end moves downward to move the shear knife on the frame plate downward, so that the shear knives on both sides move to the gate that needs to be sheared. Then, the electric push rod 2 on both sides is controlled to be opened, and the telescopic end drives the electric push rods on both sides to move closer to each other to achieve the shearing process of the gate, which can quickly achieve the shearing process of the gate.

[0010] Secondly, by controlling the operation of motor one, the output shaft rotates to drive screw one to rotate, and then drives the shearing knife on the sliding frame to move, so as to achieve shearing processing of the gate on the rear side of the bumper.

The gates at different positions of the bumper can be sheared.

[0011] Thirdly, by pulling the pull plate, the locking column leaves the locking hole inside the shear knife. At this time, the spring is in a compressed state. Then the worn shear knife is taken out from the sliding frame, and then the new shear knife is slid into the sliding frame. Then the pull plate is released. At this time, the spring rebounds quickly and drives the locking column to insert into the locking hole, so as to realize the rapid installation of the shear knife. The spring drives the locking column to insert into the locking hole inside the shear knife to realize the rapid installation of the shear knife, which makes the installation and disassembly of the shear knife very quick, significantly improves the processing efficiency, avoids the loosening phenomenon caused by vibration and the like, and helps to maintain stable shearing accuracy.

[0012] Fourthly, the supporting feet on the support frame can realize stable support for the processing device, and the side gate waste can fall into the inside of the collection box from the drop opening after shearing, so that the gate waste can be collected and the workload of the staff can be reduced.
