Description

Technical Field

[0001] This utility model relates to the technical field of injection molding machine feeding mechanism, and in particular to an adjustable workpiece feeding mechanism used on an injection molding machine. Background Technology

[0002] In injection molding production, in order to quickly remove the workpiece from the mold and transport it to a designated position after it is formed, realize the automated connection from injection molding to unloading, reduce the time loss in intermediate links, and improve the overall production efficiency, an adjustable workpiece unloading mechanism used on injection molding machines is used to accurately remove the processed workpiece from the injection molding machine and place it in a specific position.

[0003] The workpiece is usually unloaded by attaching flexible grippers to the robotic arm. During operation, the robotic arm first aligns the flexible grippers with the workpieces processed on the injection molding machine, and then the pneumatic device is activated to control multiple sets of flexible grippers to simultaneously clamp multiple sets of workpieces on the injection molding machine. Then the robotic arm moves them to the conveyor belt for subsequent processing.

[0004] Considering that the distance between different workpieces and the injection molded groove varies when unloading different workpieces, the position of the flexible chuck needs to be adjusted when using the unloading mechanism to accommodate different workpieces. However, existing mechanisms usually require disassembling and adjusting the position of the flexible chuck, which is not only cumbersome and time-consuming, but also prone to wear and tear on parts due to frequent disassembly, reducing the overall service life of the mechanism. Therefore, an adjustable workpiece unloading mechanism for use on injection molding machines is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable workpiece unloading mechanism for use on injection molding machines. It aims to solve the problem in existing technologies where, during unloading in injection molding machines, the position of the flexible chuck needs to be adjusted due to differences in workpiece size and distance from the injection groove. Existing mechanisms often rely on disassembling the flexible chuck for adjustment, which is cumbersome, time-consuming, and labor-intensive. Frequent disassembly can also lead to wear and tear on parts and shorten the overall service life of the mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable workpiece unloading mechanism used on an injection molding machine, comprising a base plate, a clamping assembly provided on the inner surface of the base plate, the clamping assembly including a flexible chuck, the outer surface of the flexible chuck penetrating and slidably connected to the inner surface of the base plate, a fixed plate being fixedly connected to the bottom end of the outer surface of the flexible chuck by bolts, the outer surface of the fixed plate being slidably connected to the inner surface of the base plate, a hinge member being hinged to the outer surface of the fixed plate, a hinge plate being hinged to the top of the outer surface of the hinge member, and a threaded member being threadedly connected to the inner surface of the hinge plate;

[0007] The clamping assembly also includes an air inlet pipe, the outer surface of which is fixedly connected to the bottom end of the outer surface of the flexible clamp, and the outer surface of the air inlet pipe is slidably connected to the outer surface of the fixed plate.

[0008] As a further description of the above technical solution:

The inner surface of the threaded cover is threadedly connected to the outer surface of the positioning ring.

[0010] As a further description of the above technical solution:

[0011] The hinge is provided in four sets, and the top of the outer surface of each of the four sets of hinges is hinged to the outer surface of the hinge plate.

[0012] As a further description of the above technical solution:

[0014] As a further description of the above technical solution:

[0023] 1. In this utility model, by rotating the threaded part, the hinge plate can be driven to move vertically, thereby simultaneously controlling the expansion and contraction of the four sets of hinges.

[0031] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of an adjustable workpiece unloading mechanism used on an injection molding machine, comprising a base plate 1. A clamping assembly 3 is provided on the inner surface of the base plate 1. The clamping assembly 3 effectively clamps the workpiece for unloading operations. The clamping assembly 3 includes a flexible chuck 301. The outer surface of the flexible chuck 301 penetrates and is slidably connected to the inner surface of the base plate 1, allowing the flexible chuck 301 to move laterally along the inner surface of the base plate 1. A fixed plate 8 is fixedly connected to the bottom end of the outer surface of the flexible chuck 301 by bolts 10, ensuring that the flexible chuck 301 remains inside the base plate 1. The outer surface of the fixed plate 8 is slidably connected to the inner surface of the base plate 1, allowing the fixed plate 8 to move laterally along the inner surface of the base plate 1, and also causing the flexible chuck 301 to move laterally along with it. A hinge 7 is hinged to the outer surface of the fixed plate 8, allowing the hinge 7 to move when it moves. The clamping assembly 3 is equipped with a hinge plate 6 hinged to the top of the outer surface of the hinge 7. When the hinge plate 6 moves vertically, it can move the hinge 7, thereby moving the fixed plate 8 laterally. The inner surface of the hinge plate 6 is threaded with a threaded part 5. When the threaded part 5 rotates, it can move the hinge plate 6 vertically by passing through and threading with the inner surface of the hinge plate 6. The clamping assembly 3 also includes an air inlet pipe 302. The outer surface of the air inlet pipe 302 is fixedly connected to the bottom end of the outer surface of the flexible chuck 301, allowing compressed air to enter the interior of the flexible chuck 301 through the air inlet pipe 302 to control the clamping effect of the flexible chuck 301. The outer surface of the air inlet pipe 302 is slidably connected to the outer surface of the fixed plate 8, allowing the fixed plate 8 to be fixed to the bottom end of the flexible chuck 301 without affecting the delivery of compressed air from the air inlet pipe 302 to the interior of the flexible chuck 301.

[0033] Reference Figures 3-4A positioning ring 11 is fixedly connected to the rear end of the outer surface of the base plate 1. The positioning ring 11 is used to position the threaded part 5 to ensure that the threaded part 5 can rotate and work stably. The bottom of the outer surface of the threaded part 5 is inserted into and rotatably connected to the inner surface of the positioning ring 11, so that the threaded part 5 can rotate flexibly in the positioning ring 11 without deviation. A threaded cover 9 is slidably connected through the outer surface of the threaded part 5. The function of the threaded cover 9 is to limit the threaded part 5 and prevent the threaded part 5 from moving axially during operation. The inner surface of the threaded cover 9 is threadedly connected to the outer surface of the positioning ring 11. The threaded connection allows for easy installation and removal of the threaded cover 9, thereby realizing the release and restoration of the limitation on the threaded part 5. There are four sets of hinges 7. The top of the outer surface of the four sets of hinges 7 is hinged to the outer surface of the hinge plate 6, so that the four sets of hinges 7 can simultaneously drive the four sets of flexible clamps 301 to move together. The bottom of the hinge 7 is C-shaped so that the hinge 7 will not interfere with the movement of the hose connected to the top of the air intake pipe 302 when it is hinged.

[0034] Reference Figures 2-4 The flexible chuck 301 has four sets, and the four sets of hinges 7 and the four sets of flexible chucks 301 are arranged in a cross shape. The cross arrangement allows the four sets of flexible chucks 301 to clamp the workpiece from different directions, improving the stability and reliability of clamping. A buffer 4 is fixedly connected to the rear end of the outer surface of the base plate 1. The buffer 4 can buffer the impact during unloading, reducing the impact on the mechanism and the workpiece. The top of the air inlet pipe 302 is provided with anti-slip texture to prevent the connection between the gas delivery hose and the air inlet pipe 302 from falling off, ensuring the stability of gas delivery. The outer surface of the flexible chuck 301 is provided with anti-slip texture, which can increase the friction between the flexible chuck 301 and the workpiece, improve the clamping effect, and prevent the workpiece from slipping during clamping. A robotic arm 2 is hinged to the rear end of the outer surface of the base plate 1. The robotic arm 2 can drive the entire unloading mechanism to move and operate, realizing the unloading operation of workpieces in different positions.

[0035] Working principle: When it is necessary to adjust the position of the four sets of flexible chucks 301, the threaded part 5 is rotated to drive the hinge plate 6 to move vertically. When the hinge plate 6 moves vertically, it can simultaneously drive the four sets of hinge parts 7 to unfold and retract. Because the hinge parts 7 are hinged to the fixed plate 8, the four sets of flexible chucks 301 can unfold and retract in a cross shape around the center point of the four sets of flexible chucks 301.

[0036] When it is necessary to replace the threaded part 5 and the four sets of hinges 7, first unscrew the bolts 10 on the four sets of fixing plates 8 to release the four sets of fixing plates 8 from limiting the four sets of flexible clamps 301. Then rotate the threaded cover 9 to release the limitation on the threaded part 5, so that the entire threaded part 5 and the four sets of hinges 7 can be removed and replaced.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
