Description

Technical Field

[0001] This application relates to the field of injection molding production and processing technology, and in particular to an automatic removal and trimming device for injection molded parts. Background Technology

[0002] Currently, injection molding is a widely used process in the production of various plastic products. Especially in large-scale industrial production, injection molding is widely used due to its high efficiency and precision. However, for some large injection molded parts, such as pallets, boxes, and canopies, manual removal is not only inefficient but also prone to workplace accidents due to their large size. Furthermore, after injection molding, these large parts usually have some waste material remaining on their surface, which requires further processing to ensure the product meets quality standards.

[0003] Existing solutions mainly include two approaches: The first is manual removal and trimming, where workers use specialized tools to remove the injection molded part from the mold and manually trim away surface debris. While simple and easy, this method is labor-intensive, inefficient, and poses safety hazards. The second is a semi-automated removal device, which typically includes a simple robotic arm that removes the injection molded part from the mold cavity, but still requires manual trimming. While this method improves efficiency to some extent, it still falls short in terms of full automation and therefore needs improvement. Utility Model Content

[0004] To facilitate the removal and trimming of injection molded parts, this application provides an automatic removal and trimming device for injection molded parts.

[0005] The automatic removal and trimming device for injection molded parts provided in this application adopts the following technical solution:

[0006] An automatic injection molding part removal and trimming device includes a support frame, a robotic arm, a material suction assembly, and a trimming assembly. The support frame is located on one side of the injection molding machine, and the robotic arm is located on one side of the support frame and is used to transfer the injection molding part onto the support frame. The support surface of the support frame is inclined. The support frame is provided with a plurality of support rods, each of which is located at the lower end of the support surface and is used to support the injection molding part. The material suction assembly and the trimming assembly are both located on the robotic arm. The material suction assembly is used to pick up the molded injection molding part, and the trimming assembly is used to trim the waste material on the injection molding part.

[0007] By adopting the above technical solution, during production, the operating robot approaches the injection molding machine and uses the suction force of the suction component to take out the molded injection part from the injection molding machine and then transfer it to the support frame. The support rod supports the injection part to be placed at an angle on the support frame.

[0008] Next, the robotic arm controls the trimming component to move to the required position, where it cuts off the waste material from the injection molded part, completing the trimming process. The entire process is highly automated, improving the efficiency of removing injection molded parts, reducing manual intervention, and lowering labor intensity; at the same time, it achieves automatic removal of waste material from the surface of the injection molded part, improving product quality and consistency.

[0009] Preferably, the suction assembly includes a fixed frame and a plurality of suction cups, with each suction cup spaced apart on the fixed frame, and the suction cups are used to grip the injection molded part.

[0010] By adopting the above technical solution, the mounting bracket serves as a carrier for installing each suction cup. The suction cups rely on vacuum to firmly lift the injection-molded part.

[0011] Preferably, the trimming assembly includes a linear cylinder and pneumatic shears. The linear cylinder is mounted on the fixed frame, and the pneumatic shears are mounted on the piston rod of the linear cylinder and are used to trim waste material on the injection molded part.

[0012] By adopting the above technical solution, when the robot arm moves to the appropriate position, it operates the linear cylinder. The linear cylinder controls the pneumatic shears to move in the direction close to the injection molded part, so that the pneumatic shears can cut off the waste material on the injection molded part and complete the trimming.

[0013] Preferably, it also includes a collection frame, which has an opening and is located below the support frame, and the collection frame is used to collect falling waste.

[0014] By adopting the above technical solution, the cut-off waste falls into the collection box below, avoiding pollution of the workshop environment.

[0015] Preferably, the support frame is provided with a plurality of limiting plates, each of the limiting plates being distributed at intervals along the periphery of the support surface, and each of the limiting plates being used to limit the injection molded part.

[0016] By adopting the above technical solution, the limiting plate can limit the periphery of the injection molded part, thereby improving the stability of the injection molded part on the support frame.

[0017] Preferably, the collection frame has through holes at both ends, which are for people's fingers to pass through.

[0018] By adopting the above technical solution, workers' fingers can pass through the through hole to grasp the collection frame and apply force to it.

[0019] Preferably, the limiting plate is detachably connected to the support frame by fasteners, which are fastening bolts or fastening screws.

[0020] By adopting the above technical solution, the limit plate can be disassembled using fasteners, making it convenient to replace the limit plate.

[0021] Preferably, the surface of the limiting plate is provided with an elastic layer.

[0022] By adopting the above technical solution, the elastic layer has good deformation ability, realizing flexible contact between the injection molded part and the limiting plate, reducing the impact damage of the injection molded part during the process of placing it into the support frame, and improving the yield and appearance quality.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] (1) By setting up a support frame, a robot arm, a suction assembly, and a trimming assembly, during production, the robot arm moves close to the injection molding machine and uses the suction force of the suction assembly to remove the molded part from the injection molding machine. Then, it is transferred to the support frame, where the support rods allow the molded part to be placed at an angle. Next, the robot arm controls the trimming assembly to move to the required position, where it cuts off the waste material from the molded part, completing the trimming process. The entire process is highly automated, improving the efficiency of removing the molded part and automatically removing waste material from the surface of the molded part.

[0025] (2) By setting up a collection box, the waste material cut off by the trimming component falls into the collection box below, thus preventing the waste material from being scattered on the ground.

[0026] (3) By setting a limiting plate, the limiting plate can limit the periphery of the injection molded part, improve the stability of the injection molded part on the support frame, and when the trimming component is trimming, the injection molded part is not easy to fall off the support frame.

[0035] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0036] This application discloses an automatic removal and trimming device for injection molded parts. (Refer to...) Figures 1 to 3 The automatic removal and trimming device includes a support frame 1, a robotic arm 2, a material suction assembly 3, and a trimming assembly 4. The support frame 1 is fixedly installed on the ground and located on one side of the injection molding machine; the robotic arm 2 is located on one side of the support frame 1 and is used to transfer the injection molded parts onto the support frame 1.

[0037] The support surface of the support frame 1 is inclined, and the injection molded part is placed inclined on the support frame 1. Support rods 5 are fixedly connected to the support frame 1, and the support rods 5 are spaced horizontally at intervals, each located at the lower end of the support surface, to support the injection molded part. The suction assembly 3 and the trimming assembly 4 are both mounted on the robot arm 2. The suction assembly 3 is used to pick up the molded injection molded part, and the trimming assembly 4 is used to trim the waste material on the injection molded part. The robot arm 2 adopts a multi-degree-of-freedom articulated design with 6 degrees of freedom, allowing for flexible angle adjustment so that the suction assembly 3 can pick up injection molded parts of different sizes and shapes.

[0038] After injection molding is complete, robot arm 2 moves to the injection molding machine and determines the position of the molded part according to a pre-programmed sequence. Next, the suction assembly 3 is activated, firmly holding the molded part in place. Then, robot arm 2 moves the suction assembly 3 and the molded part to support frame 1, smoothly transferring the part onto it. Subsequently, the trimming assembly 4 is activated, trimming away waste material from the surface of the molded part along a preset path. After trimming, robot arm 2 and suction assembly 3 work together again to remove the molded part from support frame 1. The entire process is coordinated by the control system, ensuring smooth, safe, and reliable operation.

[0039] Specifically, the suction assembly 3 includes a fixed frame 31 and several suction cups 32. The fixed frame 31 is fixed on the robot arm 2, and the suction cups 32 are spaced apart on the fixed frame 31. In this embodiment, there are four suction cups 32, which are used to hold the injection molded parts tightly.

[0040] The trimming assembly 4 includes a linear cylinder 41 and pneumatic shears 42. The linear cylinder 41 is mounted on the mounting bracket 31, and the pneumatic shears 42 are mounted on the piston rod of the linear cylinder 41 and are used to trim waste material on the injection molded part. The linear cylinder 41 is used to control the pneumatic shears 42 to move closer to or away from the injection molded part. The linear cylinder 41 can also be replaced with other linear control devices, such as an electric push rod.

[0041] When the robotic arm 2 moves to the appropriate position, it activates the linear cylinder 41, which controls the pneumatic shears 42 to move closer to the injection molded part, thus cutting off the waste material on the injection molded part and completing the trimming. When the suction assembly 3 needs to hold the injection molded part tightly, the linear cylinder 41 controls the pneumatic shears 42 to move away from the injection molded part to avoid interfering with the suction cup 32's material suction.

[0042] Below the support frame 1, there is a collection box 6. The collection box 6 is rectangular and has an opening. The collection box 6 is used to collect waste materials that fall from the support frame 1 to prevent pollution of the workshop environment. The collection box 6 also has through holes 7 at both ends for personnel to pass through.

[0043] In addition, several limiting plates 8 can be detachably connected to the support frame 1. The limiting plates 8 are spaced apart along the periphery of the support surface, and each limiting plate 8 is used to limit the injection molded part, thereby improving the stability of the injection molded part on the support frame 1. In this embodiment, the limiting plates 8 are locked to the support frame 1 by fasteners, which are fastening bolts or fastening screws. The fasteners allow the limiting plates 8 to be detachable, making it convenient to replace the limiting plates 8. In some embodiments, an elastic layer (not shown in the figure) is provided on the surface of the limiting plate 8. The elastic layer is made of rubber, sponge or latex. The elastic layer has good deformation ability, realizing flexible contact between the injection molded part and the limiting plate 8, reducing the impact damage to the injection molded part during the process of placing it into the support frame 1, and improving the yield and appearance quality.

[0044] The implementation principle of the automatic injection molding part removal and trimming device in this application embodiment is as follows: During production, the operating robot 2 approaches the injection molding machine and uses the suction force of the suction component 3 to remove the molded injection part from the injection molding machine and then transfer it to the support frame 1. The injection part is placed on the support frame 1 at an angle by the support of the support rod 5.

[0045] Next, the robotic arm 2 controls the trimming component 4 to move to the required position, where it cuts off the waste material from the injection molded part, completing the trimming process. The entire process is highly automated, improving the efficiency of removing injection molded parts, reducing manual intervention, and lowering labor intensity; at the same time, it achieves automatic removal of waste material from the surface of the injection molded part, improving product quality and consistency.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
