[0001] This application belongs to the field of injection molding technology, and specifically relates to a part removal device for an injection molding machine and an injection molding machine. Background Technology

[0002] In the production of injection molded parts, when using a robotic arm to remove the product from the mold, a part-retrieving device is needed to replace manual handling. This reduces the safety risks associated with manual operation and minimizes defects such as dragging and scratches on the product. Currently, most part-retrieving devices used in the industry are of fixed dimensions. These devices are difficult to adapt to the shape of the product, have low compatibility, and result in a wide variety of part-retrieving devices of different types and models, complex assembly and disassembly processes, and low production efficiency. Utility Model Content

[0003] In view of at least one of the above-mentioned defects or deficiencies in the prior art, this application provides a part-retrieving device for an injection molding machine and an injection molding machine, which can effectively improve the compatibility of the part-retrieving device, meet the part-retrieving operation requirements of injection molded parts of different sizes, and improve production efficiency.

[0004] To achieve the above objectives, this application provides a part-retrieving device for an injection molding machine, the part-retrieving device comprising:

[0005] A fixed support frame, comprising a plurality of fixed supports symmetrically arranged in a first direction;

[0006] Multiple movable arms are arranged on multiple fixed arms extending along a second direction and are capable of translation along the first and second directions;

[0007] Multiple part-retrieving execution components are respectively disposed at the ends of the multiple movable arms and are capable of translation along the second direction; and

[0008] The locking structure includes an arm locking structure capable of locking the movable arm onto the fixed arm and an actuator locking structure capable of locking the part-retrieving component onto the end of the movable arm.

[0009] In some embodiments, the fixed arm has a fixed arm groove extending along the first direction, the movable arm has a movable arm groove extending along the second direction, and the arm locking structure includes a first connecting component capable of passing through the movable arm groove and the fixed arm groove to lock the movable arm and the fixed arm.

[0010] In some embodiments, the actuator locking structure includes a second connecting component capable of connecting the retriever actuator and the movable arm slide to lock the retriever actuator and the movable arm.

[0011] In some embodiments, the first connecting component and / or the second connecting component are detachable connecting components.

[0012] In some embodiments, the component retrieval execution component includes:

[0013] Adsorption components, used for adsorbing injection molded parts; and

[0014] The universal adjustment bracket has two axial ends forming a universal movable end and a fixed end, respectively. The universal movable end is connected to the adsorption member, and the fixed end is connected to the movable support arm through the actuator locking structure.

[0015] In some embodiments, the component retrieval assembly further includes a connecting block, through which the adsorption component is connected to the universal movable end.

[0016] In some embodiments, the adsorption element includes a suction cup and an air tube communicating with the suction cup, and the connecting block is provided with a connecting groove through which the air tube passes to connect to the suction cup.

They are used together with the following detailed description to explain the embodiments of this application, but do not constitute a limitation on the embodiments of this application. For those skilled in the art, other drawings can be obtained based on the structures shown in these drawings without any inventive effort. In the drawings:

[0024] Explanation of reference numerals in the attached figures

[0025] Detailed Implementation

[0026] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0027] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0028] like Figure 1 As shown in the exemplary embodiment of this application, a part-retrieving device for an injection molding machine is provided. The part-retrieving device includes a fixed base 1, a plurality of movable arms 2, a plurality of part-retrieving execution components 3, and a locking structure. The fixed base 1 includes a plurality of fixed arms 101 symmetrically arranged in a first direction D1; the plurality of movable arms 2 extend along a second direction D2 and are disposed on the plurality of fixed arms 101, each movable arm 2 being capable of translation along the first direction D1 and the second direction D2; the plurality of part-retrieving execution components 3 are respectively disposed at the ends of the plurality of movable arms 2 and are all capable of translation along the second direction D2; the locking structure includes an arm locking structure 4 and an execution component locking structure 5, wherein the arm locking structure 4 can lock the movable arms 2 onto the fixed arms 101, and the execution component locking structure 5 can lock the part-retrieving execution components 3 onto the ends of the movable arms 2.

[0029] Therefore, in the part-retrieving device of this exemplary embodiment, the bidirectional translational adjustment of the movable support arm 2 enables wide compatibility of the device's basic dimensions, covering injection molded parts of different lengths and widths, and meeting the part-retrieving requirements of injection molded parts of different sizes. Simultaneously, by translating the part-retrieving execution component 3 on the movable support arm 2, the distance between the two part-retrieving execution components 3 located at both ends of the movable support arm 2 can be adjusted, achieving flexible distribution of the suction points according to the contour of the injection molded part, eliminating shape adaptation blind spots, and effectively fine-tuning the part-retrieving execution component 3 when the position of the movable support arm 2 is fixed, ensuring that it can be aligned with the target suction point for part retrieval. Furthermore, the dual-stage synergy of the support arm locking structure 4 and the execution component locking structure 5 ensures the stability against displacement in the high-speed part-retrieving process after adjustment. Overall, the part-retrieving device of this exemplary embodiment achieves the core effect of single-device compatibility with multiple product specifications, significantly reducing the number of dedicated tooling and changeover time, and improving production efficiency.

[0030] Furthermore, when the movable support arm 2 is hinged to the fixed support arm 101, the movable support arm 2 can not only move bidirectionally by moving the hinge point, but also rotate relative to the fixed support arm 101, thereby adjusting the yaw angle of the movable support arm 2 and thus adjusting the relative position of the corresponding part-picking execution component 3. In this embodiment, the fixed base 1 can be fixedly installed on the robotic arm of the injection molding machine, so that the entire device can move with the robotic arm to pick up parts.

[0031] exist Figure 1 In the illustrated embodiment, the fixed support frame 1 has two symmetrically arranged fixed support arms 101, and two movable support arms 2 are respectively mounted on the two fixed support arms 101. Two part-picking execution components 3 are respectively provided at both ends of the movable support arms 2. The two movable support arms 2 can move closer to or further away from each other along the first direction D1, thereby adjusting the distance between the two opposing part-picking execution components 3. By adjusting the position of the movable support arms 2 in the second direction D2, the position of the two part-picking execution components 3 in the second direction D2 can be adjusted. Of course, this application does not limit the specific number of part-picking execution components 3; their specific number can be determined according to the actual size and quantity of the injection molded part, while the number of movable support arms 2 and fixed support arms 101 is determined according to the number of part-picking execution components 3.

[0032] In one embodiment, the fixed support arm 101 is provided with a fixed arm groove 102 extending along a first direction D1, and the movable support arm 2 is provided with a movable arm groove 201 extending along a second direction D2. The support arm locking structure 4 includes a first connecting component 401 capable of passing through the movable arm groove 201 and the fixed arm groove 102 to lock the movable support arm 2 and the fixed support arm 101. In this embodiment, the fixed arm groove 102 serves as a guide rail on the fixed support arm 101, effectively constraining the movement path of the movable support arm 2 in the first direction D1, preventing the movable support arm 2 from angularly deflecting during translation, and ensuring the parallelism of the multi-arm spacing adjustment. The movable arm slide 201 extends along the second direction D2 and overlaps with the fixed arm slide 102 to form a bidirectional sliding interface, realizing the independent extension and retraction freedom of the movable arm 2 in the second direction D2, decoupling it from the movement in the first direction, thereby supporting independent adjustment of length and width dimensions. After the movable arm 2 moves into place, the movable arm 2 is locked after the first connecting component 401 passes through the double slides simultaneously, fixing the position of the movable arm 2 in the first direction spacing and the second direction in a single operation, reducing locking steps, significantly simplifying the locking process and suppressing the risk of compound displacement, ultimately achieving efficient and stable multi-size compatibility.

[0033] Furthermore, the actuator locking structure 5 includes a second connecting component 501 that can pass through the part-retrieving actuator 3 and the movable arm slide 201 to lock the part-retrieving actuator 3 and the movable arm 2. After the part-retrieving actuator 3 is translated to the target position along the movable arm slide 201, the position of the part-retrieving actuator 3 in the second direction can be fixed by the second connecting component 501 passing through the part-retrieving actuator 3 and the movable arm slide 201, and the positioning and locking can be completed in a single operation, eliminating the need for secondary adjustment.

[0034] In the above embodiments, both the first connecting component 401 and the second connecting component 501 can be detachable connecting components, such as bolt components or pin components, to facilitate the disassembly and assembly of the movable support arm 2 and the part-removing execution component 3; or, one of the first connecting component 401 and the second connecting component 501 can be a detachable connecting component and the other can be a non-detachable connecting component, such as welded screws and nuts, etc. This application does not limit this.

[0035] In one embodiment, the part-retrieving execution component 3 includes an adsorption element 301 and a universal adjustment bracket 302. The adsorption element 301 is used to adsorb the injection-molded part. The axial ends of the universal adjustment bracket 302 are respectively formed as a universal movable end and a fixed end. The universal movable end is connected to the adsorption element 301 through an execution locking structure 5, and the fixed end is connected to the movable support arm 2. In this embodiment, the adsorption element 301 achieves part-retrieving without damage through negative pressure adsorption, which is particularly suitable for curved injection-molded parts. The universal movable end of the universal adjustment bracket 302 is connected to the adsorption element 301, giving the adsorption element a multi-degree-of-freedom dynamic posture adjustment capability, realizing 360° swing without dead angles, so that the adsorption element 301 is always perpendicular to the surface of the product, eliminating adsorption failure caused by product shape or positioning deviation. Its fixed end is connected to the movable support arm 2 through the execution locking structure 5, thereby realizing rapid displacement adjustment of the part-retrieving execution component 3.

[0036] Furthermore, the part-retrieving execution component 3 also includes a connecting block 303, through which the adsorption component 301 is connected to the universal movable end. The connecting block 303 serves as the intermediate interface between the adsorption component 301 and the universal movable end, absorbing high-frequency vibrations of the universal bracket through physical isolation, preventing scratches on the product caused by micro-vibration failure of the sealing edge of the adsorption component 301. In addition, due to the modular nature of the connecting block 303, it can form a detachable connection with the universal movable end, supporting quick assembly and disassembly for replacing adsorption components 301 of different specifications or for independent maintenance, significantly reducing operating costs.

[0037] In one embodiment, the adsorption component 301 includes a suction cup 3011 and an air tube 3012 communicating with the suction cup 3011. The connecting block 303 is provided with a connecting groove 3031, through which the air tube 3012 passes to connect to the suction cup 3011. In this embodiment, the suction cup 3011 achieves non-destructive part removal through the pneumatic adsorption of the air tube 3012, which is particularly suitable for curved injection molded parts. The connecting groove 3031 serves as a through hole for the air tube to pass through the connecting block 303. Its gap design gives the air tube 3012 the freedom of swing during universal adjustment, avoiding bending and breakage of the tube during movement. The layout of the air tube passing through the groove allows the connecting block 303 to solidly wrap the air tube section, enhancing the vibration isolation effect and further reducing the risk of micro-vibration failure of the suction cup sealing edge. At the same time, the integrated wiring design eliminates motion interference and supports quick docking or replacement of the air tube 3012, extending the service life of the device and improving maintenance efficiency.

[0038] In one embodiment, the universal adjustment bracket 302 includes a ball head 3021, a sleeve 3022, and an adjustment arm 3023. The ball head 3021 is embedded in the sleeve 3022. The sleeve 3022 can be an integral sleeve or a type of sleeve. Figure 1The split sleeve shown (formed by the joining of two bent plates) has an inner end of sleeve 3022 that is the fixed end described above. One end of the adjusting arm 3023 is connected to the peripheral wall of ball head 3021, and the other end is formed as the universal movable end that extends out of the outer end of sleeve 3022 described above. In this embodiment, the ball head 3021 is embedded in the sleeve 3022 to form a multi-directional rotating joint, realizing stepless angle adjustment of the adsorption element 301. The spherical contact of the ball head 3021 can provide anti-overturning stability. The inner end of the sleeve 3022 serves as a fixed end connected to the movable support arm 2, improving the stability of the adsorption element 301. The root of the adjusting support arm 3023 is fixed to the peripheral wall of the ball head. The rotation of the ball head 3021 is converted into the displacement of the end of the support arm, which significantly improves the adjustment efficiency and accuracy of the adsorption element 301. Furthermore, the universal movable end extending from the sleeve 3022 expands the working range of the adsorption element 301. In other embodiments, the adjusting support arm 3023 can also buffer sudden impacts through elastic deformation, ultimately achieving highly stable and efficient adaptive part removal on complex curved surfaces.

The part-retrieving device can be mounted on the robotic arm of the injection molding machine via a fixed bracket 1.
