[0002] Casters are a general term, including movable casters, fixed casters and movable casters with brakes. Movable casters are also called universal wheels, and their structure allows 360-degree rotation; fixed casters are also called fixed casters, which have no rotating structure and cannot turn. Usually, the two types of casters are generally used in combination. For example, the structure of a trolley is two fixed wheels in the front and two universal wheels in the back near the push handle. Casters are made of various materials, such as PP casters, PVC casters, PU casters, cast iron casters, nylon casters, TPR casters, iron core nylon casters, iron core PU casters, etc.

[0003] Injection molded polyurethane casters have good elastic properties and moderately high compression resistance and traction, and are particularly suitable for manual or mechanical traction on smooth surfaces. During production, the wheel hub of the caster is placed in the mold of the injection molding equipment and the outer ring is injection molded. In the prior art, one method is pure manual loading, and the other is loading by a robot to improve efficiency. However, before loading by the robot, workers are generally required to place the wheel hub workpieces one by one in the designated position, and the workers still need to continue operating, which is labor-intensive and increases labor costs.

[0016] In order to solve the above technical problems, such as Figure 1-2 As shown, the utility model designs an automated caster injection molding device, including an injection molding machine body 1, a manipulator 2, and a material storage mechanism, wherein the manipulator 2 is used to transfer the workpiece in the material storage mechanism to the mold of the injection molding machine body 1, and the material storage mechanism includes a base 3, on which a fixed support plate 4 is arranged, and a fixed material storage plate 5 is arranged on the front side of the support plate 4, and the material storage plate 5 is fixedly connected to the support plate 4 by a support rod, and the material storage plate 5 is provided with four material storage troughs 6 symmetrical in pairs, and each material storage trough 6 is provided with a feeding port on the side facing outward, and a lifting cylinder 7 is also arranged on the front side of the support plate 4, and the piston rod of the lifting cylinder 7 is downward and connected to a lifting plate 8, and material storage racks 9 are symmetrically arranged on the left and right sides of the lifting plate 8, and the material storage racks 9 are provided with material storage rails, and the width of the material storage rails is adapted to the diameter of the workpiece of the caster hub 11, so that a plurality of caster hubs 11 can be vertically arranged in the material storage rails. The material storage rack 9 is arranged in a vertical direction. The top of the material storage rack 9 is provided with a discharge port connected to the material storage track, and the discharge port is used for workers to put workpieces in. The bottom of the material storage rack 9 is provided with a discharge port 10 on the side facing the material storage plate 5. The discharge port 10 is connected to the discharge track. An arc-shaped guide portion is preferably provided between the material storage track and the discharge port 10, so that the workpieces in the material storage track will be guided to the discharge port 10 under the action of gravity. The front side of the material storage rack 9 is provided with a transparent baffle (not shown in the figure, the baffle is used to prevent the workpiece from falling out from the front side of the material storage rack 9, and the transparent material allows the staff to directly observe the internal situation. The material storage rack 9 is used to be driven by the lifting cylinder 7 to pass through the material storage tank 6 of the material storage plate 5. The caster hub 11 located at the bottom of the material storage rack 9 can be sent into the material storage tank 6 to complete automatic feeding. The manipulator 2 can transfer the material to the mold of the injection molding machine body 1 after taking the material from the material storage plate 5 through the inner support core shaft.

[0017] Furthermore, the device also includes a pushing mechanism, which includes a push plate 12, a linear cylinder 13, and a pushing rod 14. The push plate 12 is located between the support plate 4 and the storage plate 5. The linear cylinder 13 is installed on the rear side of the support plate 4 and its piston rod is fixedly connected to the push plate 12. The front side of the push plate 12 is provided with four symmetrical pushing rods 14. The diameter of the pushing rod 14 is larger than the inner hole diameter of the caster hub 11. The pushing rod 14 can pass through the through hole of the storage trough 6. Therefore, the linear cylinder 13 drives the push plate 12 to move forward so that the pushing rod 14 can push the caster hub 11 in the storage trough 6 forward a certain distance to the inner support core shaft of the manipulator 2.

[0018] Furthermore, downwardly extending limit plates 15 are provided on the left and right sides of the bottom of the material storage plate 5, and the limit plates 15 are used to block the discharge port 10 to prevent the caster hub 11 from falling out when the material storage rack 9 is at the bottom of the stroke.

[0019] During specific work, the storage rack 9 is initially located at the lowest end of its stroke. At this time, its discharge port 10 corresponds to the limit plate 15. The worker adds the caster hub 11 workpiece from the discharge port of the discharge rack. After the discharge is completed, the lifting cylinder 7 raises the storage rack 9. During its upward movement, the caster hub 11 workpiece at the bottom will flow to the vacant storage slot 6 of the storage plate 5. Finally, the storage rack 9 will drop and reset. At this time, the linear cylinder 13 drives the push plate 12 to move forward so that the ejector rod 14 can push the caster hub 11 in the storage slot 6 forward a certain distance to the inner support core shaft of the manipulator 2 to complete automatic material picking. The utility model designs a storage mechanism for automated injection molding equipment. After the worker puts a large number of workpieces into the storage rack 9 at one time, it will automatically fill in the designated position of the storage plate 5 for the manipulator 2 to take, which can reduce the labor intensity of the workers and reduce labor costs.
