Description

Technical Field

[0001] This utility model relates to the field of soft rubber injection molding product manufacturing technology, and in particular to a multi-claw feeding device for injection molding products based on adaptive adjustment. Background Technology

[0002] The injection molding process begins with feeding plastic raw materials into the injection molding machine barrel via a hopper. After heating and melting, the material is injected into the mold cavity under the push of the screw. After pressure holding, cooling, and shaping, the mold is opened and the product is demolded, completing the molding process. The molded product then undergoes subsequent processing such as deburring, quality inspection, and packaging. A multi-claw unloading device plays a crucial role in this process. By intelligently adjusting the gripping force and angle, it adapts to injection molded products of different sizes and shapes, accurately removing the demolded product from the mold and transferring it to subsequent workstations. Using a multi-claw unloading device not only avoids product damage caused by manual operation and improves product qualification rates, but also enables 24-hour uninterrupted automated production, significantly improving production efficiency. Its adaptive adjustment function also allows the production line to quickly switch between different product production, reducing changeover costs and optimizing the flexibility and stability of the entire injection molding production process.

[0003] In existing technologies, multi-claw unloading devices for injection molded products utilize motors, lead screws, nuts, hydraulics, or pneumatics to drive the movement of multiple claws. After the inspection system confirms that the product has been molded and demolded, the device adjusts the claw arm spacing according to the product's size and shape through a control system. For example, for products with rough surfaces that cannot be gripped and require traceless handling (e.g., thicker at the top and thinner at the bottom), a ring-like gripping operation is used to achieve the gripping, and then a robotic arm transfers the product to a designated position for unloading. Furthermore, some unloading devices combine a rotating disk and a pressing mechanism with processes such as milling sprues, ultimately allowing an external robotic arm to complete the product placement on the disk, achieving automated connection between demolding and subsequent processes for injection molded products.

[0004] In the automation of injection molding production, multi-jaw unloading devices are key equipment for achieving rapid product transfer. Currently, most traditional multi-jaw unloading devices for injection molding employ fixed structures or simple mechanical adjustments, with fixed clamping component positions that are difficult to adapt flexibly to differences in the discharge port position and material bin placement of different injection molding machines. When faced with diverse production scenarios or equipment layout adjustments, these devices cannot precisely control the position of the soft clamps, often leading to misalignment and collisions between the product and the target workstation during the unloading process. This not only reduces unloading efficiency but also easily causes quality defects such as surface damage and structural deformation of the product. Therefore, an adaptive adjustment-based multi-jaw unloading device for injection molding is proposed to solve these problems. Utility Model Content

[0028] Reference Figure 1 , Figure 2The feeding mechanism includes a feeding push rod 9, which is responsible for pushing materials or products through the feeding path.

The external part of the feeding push rod 9 is fixedly connected to the inside of the fixed support block 4, and a fixed plate 8 is fixedly connected to the external part of the feeding push rod 9. The drive end of the feeding push rod 9 is fixedly connected to the left side of the connecting support block 7. Two guide shafts 5 are fixedly connected inside the fixed support block 4, and guide sliding blocks 6 are fixedly connected to the external parts of both guide shafts 5. The guide shafts 5 are used to guide the precise movement of the feeding mechanism and the clamping device, and guide sliding blocks 6 are installed on them. The guide sliding blocks 6 are hexagonal in shape to ensure that they can slide smoothly within the set track. The external parts of both guide sliding blocks 6 are fixedly connected to the front and rear ends of the connecting support block 7. The main function of the guide shafts 5 and guide sliding blocks 6 is to ensure that the feeding system maintains linear movement during operation and to reduce offset and error.

[0029] The fixed support block 4 has an adjustment groove inside. Both ends of the two guide shafts 5 are fixedly connected to the adjustment groove. Both ends of the fixed plate 8 are fixedly connected to the adjustment groove. The inner wall of the adjustment groove has a guide groove.

[0030] The guide sliding block 6 is a hexagonal block, and mounting blocks are provided on the left and right sides of the connecting support block 7. The adjacent sides of the two guide sliding blocks 6 are fixedly connected to the distant sides of the mounting blocks.

[0031] Working principle: The feeding motor 2 fixed on the top of the support beam 1 starts, thereby driving the fixed ring 3 fixed on the drive end of the feeding motor 2 to rotate. The fixed ring 3 drives the two fixed support blocks 4 fixed outside the fixed ring 3 to rotate, thereby driving the connecting support block 7 sliding inside the fixed support block 4 to rotate, thereby realizing the position adjustment of the soft clamp 14 to achieve the purpose of feeding the soft clamp 14.

[0032] During the clamping process of the flexible clamp 14, the air pipe 15 located outside the flexible clamp 14 adjusts the air pressure inside the flexible clamp 14 through the externally connected air pressure device, thereby changing the shape of the flexible clamp 14. Specifically, the two clamping teeth of the flexible clamp 14 are brought closer to each other, thereby completing the clamping of the material. Then, the flexible clamp 14 is reset by reversing the feeding motor 2.

[0033] The feeding push rod 9, which is fixed inside the fixed support block 4, is activated. With the help of the fixed plate 8 outside the feeding push rod 9, it pushes the connecting support block 7 to slide. The two guide shafts 5, which are fixed inside the fixed support block 4, and the two guide sliding blocks 6, which are fixed at both ends of the connecting support block 7, cooperate with each other to connect the connecting support block 7, thereby driving the soft clamp 14 to carry the material to the designated position.

[0034] Then, the adjusting push rod 17 fixed inside the clamping support block 10 is activated, which drives the sliding fixing block 16 to slide inside the clamping support block 10, thereby driving the clamping fixing block 13 to slide, and then driving the soft clamp 14 to slide, so that the soft clamp 14 can make fine adjustments to the placement position of the material, thereby ensuring that the material can be accurately placed at the placement point.

[0035] 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.
