Description

Technical Field

[0001] This utility model relates to the field of parts removal mechanisms, specifically a cavity removal mechanism for an automotive bumper injection mold. Background Technology

[0002] Car bumpers are safety devices that absorb and mitigate external impacts and protect the front and rear of the vehicle. They also affect the appearance of the car. Injection molding is a common molding method for car bumpers. The cavity removal mechanism is crucial for ensuring the production efficiency and quality of bumpers. It can quickly and accurately remove the bumper from the mold cavity after injection molding to avoid product damage. Vacuum adsorption positioning mechanisms are usually used, such as the non-destructive automatic flipping bracket for removing injection molded products, which removes the product from the fixed mold side through vacuum adsorption.

[0003] In the operation of existing car bumper injection mold cavity removal mechanisms, the car bumper is removed from the injection mold cavity using a vacuum suction cup. However, because the finished car bumper has a curved surface structure, the suction cup of the traditional removal mechanism has defects: it can only adsorb the flat part of the car bumper, and cannot adapt to and complete the adsorption and lifting operation of both the surface and the plane. When removing the part, it can only adsorb through a few flat areas, resulting in a small contact area between the suction cup and the car bumper workpiece, and the vacuum adsorption force is not evenly distributed. During the removal process, slight shaking or external interference may occur, which may cause adsorption failure and thus cause the car bumper to fall off. Utility Model Content

[0005] The objective of this utility model can be achieved through the following technical solutions: A cavity part removal mechanism for an automotive bumper injection mold includes a first crossbeam and a second crossbeam. A connecting piece is fixedly installed on one side of both the first and second crossbeams near their center. Fixing plates are fixedly installed at equal intervals on the other side of both the first and second crossbeams. An adaptive component is provided on one side of each of the multiple sets of fixing plates. A suction cup part removal component is fixedly installed at one end of each of the multiple sets of adaptive components.

[0006] Preferably, each of the multiple sets of adaptive components includes a telescopic sleeve, one end of each of the multiple sets of telescopic sleeves is fixedly connected to one side of the fixed plate, each of the multiple sets of telescopic sleeves has a movable hole inside, and each of the two ends of the multiple sets of telescopic sleeves has a through hole at the lower part of its interior. Each of the two through holes has a bearing block fitted inside, and one side of each of the two bearing blocks is fixedly connected to the two ends of the telescopic sleeve by a fixing bolt.

[0011] The beneficial effects of this utility model are: This invention utilizes the flexible rotation of a movable ball within a groove, combined with the limiting assistance of a connecting block, to allow the suction cup assembly to adjust at multiple angles according to the curvature of the bumper surface.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] Please refer to Figure 1 As shown, a cavity part removal mechanism for an automotive bumper injection mold includes a first crossbeam 1 and a second crossbeam 2. A connecting piece 3 is fixedly installed on one side of the first crossbeam 1 and the second crossbeam 2 near the center. Fixing plates 4 are fixedly installed at equal intervals on the other side of the first crossbeam 1 and the second crossbeam 2. An adaptive component 5 is provided on one side of each set of fixing plates 4. A suction cup part removal component 6 is fixedly installed at one end of each set of adaptive components 5.

[0016] In a specific embodiment, the first crossbeam 1 and the second crossbeam 2 serve as the load-bearing frame of the entire mechanism. They are connected to the external drive device robotic arm via the connector 3, providing power and movement trajectory support for the part-removing action. This ensures that the mechanism can move precisely between the mold cavity and the placement area. The suction cup is usually a vacuum suction cup. During operation, air is drawn out by the connected vacuum device to create a negative pressure inside the suction cup. Atmospheric pressure is used to firmly adhere the injection-molded car bumper. Since the bumper is large and thin-walled, multiple suction cups can distribute the force, thereby removing the finished car bumper from the injection mold. The suction cup part-removing component 6 is common in the prior art and will not be described in detail here.

[0017] Please refer to Figures 1 to 4As shown, as a technical optimization scheme of this utility model, each of the multiple sets of adaptive components 5 includes a telescopic sleeve 51. One end of each set of telescopic sleeves 51 is fixedly connected to one side of the fixing plate 4. Each set of telescopic sleeves 51 has a movable hole 55 inside. Each set of telescopic sleeves 51 has a through hole 54 at the lower part of both ends inside. Each of the two through holes 54 has a bearing block 53 fitted inside. One side of each of the two bearing blocks 53 is fixedly connected to both ends of the telescopic sleeve 51 by a fixing bolt 52.

[0018] Furthermore, a fixing plate 56 is fixedly installed on the inner wall of each of the multiple sets of telescopic sleeves 51. A fixing cylinder 58 is fixedly installed at one end of the fixing plate 56. A telescopic guide rod 511 is slidably sleeved inside the fixing cylinder 58. A movable plate 59 is fixedly connected to the outer side of the telescopic guide rod 511 near the center. A telescopic spring 57 is fixedly installed at one end of the fixing plate 56. One end of the telescopic spring 57 is fixedly installed on the upper end of the movable plate 59, and the inner side of the telescopic spring 57 is sleeved on the outer side of the fixing cylinder 58. Limiting blocks 510 are fixedly connected to the outer side of each movable plate 59. Two limiting blocks 510 are slidably sleeved inside the movable hole 55 of the telescopic sleeve 51. The lower ends of the two limiting blocks 510 restrict contact with the upper end of the bearing block 53.

[0019] Furthermore, an installation block 512 is fixedly installed at one end of the telescopic guide rod 511. A ball groove 513 is provided inside the installation block 512. A movable ball 514 is movably connected inside the ball groove 513. A connecting block 515 is movably fitted on the semi-circular side of the movable ball 514. One side of the connecting block 515 is fixedly installed at the lower end of the installation block 512. A connecting rod 516 is fixedly connected to the lower part of the outer wall of the movable ball 514. The lower end of the connecting rod 516 is fixedly installed at the upper end of the suction cup picking assembly 6.

[0020] In a specific embodiment, when the suction cup assembly 6 begins to contact the bumper surface, if the surface is curved, the movable ball 514 rotates within the ball groove 513, causing the suction cup assembly 6 to adjust its angle to maintain a contact with the curved surface. The movable ball 514 will rotate flexibly within the ball groove 513 of the mounting block 512. At the same time, the connecting block 515 limits and assists the movement of the movable ball 514, ensuring that the suction cup assembly 6 can adjust at multiple angles according to the curvature of the bumper surface to adapt to different curved surface shapes. Meanwhile, the telescopic guide rod 511 slides inside the fixed cylinder 58, and the movable piece 59 compresses the telescopic spring 57. The spring force is used to make the suction cup gradually adhere to the surface of the bumper. As the suction cup assembly 6 is completely attached to the surface of the bumper, a sealed space is formed inside the suction cup. By means of air extraction, a negative pressure is generated inside the suction cup, which firmly adheres to the flat or curved surface of the bumper. During this process, the limiting block 510 contacts the bearing block 53 to limit the excessive extension and retraction of the telescopic guide rod 511, thereby realizing the process of removing the finished car bumper.

[0021] In use, when the suction cup assembly 6 begins to contact the bumper surface, if the surface is curved, the movable ball 514 rotates within the ball groove 513, causing the suction cup assembly 6 to adjust its angle to maintain a contact with the curved surface. The movable ball 514 will rotate flexibly within the ball groove 513 of the mounting block 512. Simultaneously, the connecting block 515 limits and assists the movement of the movable ball 514, ensuring that the suction cup assembly 6 can be adjusted at multiple angles according to the curvature of the bumper surface to adapt to different curved shapes. Simultaneously, the telescopic guide rod 511 slides within the fixed cylinder 58, and the movable plate 59 compresses the telescopic spring 57. The spring force is used to gradually bring the suction cup into contact with the surface of the bumper. As the suction cup assembly 6 fully contacts the surface of the bumper, a sealed space is formed inside the suction cup. By means of air extraction, a negative pressure is generated inside the suction cup, thus firmly adhering it to the flat or curved surface of the bumper. During this process, the limiting block 510 contacts the bearing block 53, limiting the excessive extension and retraction of the telescopic guide rod 511, thereby realizing the process of removing the finished car bumper.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
