Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to an injection molding device. Background Technology

[0002] In many cases, to reduce subsequent processing steps, inserts (such as metal nuts) are placed in the mold before injection molding. Then, molten plastic is injected into the mold under high pressure, encasing the insert to form a single, integrated structure. This design allows products to combine the strength and conductivity of metal with the insulation and moldability of plastic, achieving complex functions. It also reduces assembly steps, lowers labor costs, and improves product reliability.

[0003] However, the cycle time for injection-molded products with inserts is between 30 and 70 seconds, which is relatively short and difficult to operate manually. Therefore, a robotic arm is generally required. The robotic arm uses grippers mounted above it to pick up and eject the inserts. Since injection-molded parts typically contain more than one insert, and each insert involves picking and ejecting processes, the gripping and placement of each insert requires at least two power sources. This necessitates multiple power sources for the robotic arm. To avoid interference between these power sources, the required installation space is large, resulting in a bulky and costly robotic arm structure. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an injection molding equipment that can reduce the introduction of power source for the robotic arm, reduce installation space and reduce costs.

[0005] This utility model is achieved through the following technical solution:

The automatic clamping device includes:

[0007] robot;

[0008] An elastic gripper is disposed on the free end of the robot. The elastic gripper includes an elastic clamp, a push rod, and a first driving member.

The inner wall of the spring piece is configured to clamp the insert. The first driving member is configured to drive the push rod to move, thereby causing the insert to disengage from the elastic part.

The output end of the guide drive is configured to drive the inserts located in the guide groove to move along the guide groove.

[0017] Furthermore, the injection molding equipment also includes a gate-cutting device configured to cut off the gate on the product.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] like Figures 1 to 5As shown in the figure, an embodiment of this utility model provides an injection molding equipment for producing injection-molded products with inserts 7. The injection molding equipment mainly includes an injection molding machine 1, a feeding device 2, an automatic clamping device, and an automatic packaging mechanism 10. The injection molding machine 1 is used for injection molding, which is prior art and will not be described in detail here. The feeding device 2 is used to sequentially convey multiple inserts 7 to the clamping station. The automatic clamping device is used to grab the inserts 7 located at the clamping station and place them into the injection mold of the injection molding machine 1, so that the product injection-molded by the injection molding machine 1 can form an integrated structure with the inserts 7. Furthermore, the automatic clamping device can also clamp the product injection-molded in the injection molding machine 1 and convey it to the automatic packaging mechanism 10, where the automatic packaging mechanism 10 completes the product packaging.

[0032] Specifically, the automatic gripping device includes a robot 4 and a gripper mounted on the free end of the robot 4. The gripper is used to grip and place the insert 7 and the product, and the robot 4 drives the gripper to move between different workstations so that the insert 7 and the product can flow between them. Preferably, the robot 4 is a six-axis robot, which has the advantages of high precision and high stability, and can complete complex spatial trajectory movements, adapting to the needs of narrow spaces and multi-angle operations. Furthermore, the injection molding machine 1, the feeding device 2, the control system module 40 of the robot 4, and the automatic packing mechanism 10 are arranged around the robot 4 and within its working range, thereby maximizing space saving and improving production efficiency.

[0033] Further reference Figure 2 The fixture includes a fixed base 62 and an elastic gripper 5. The fixed base 62 is fixedly connected to the free end of the robot 4 by screws (not shown in the figure), and the elastic gripper 5 is mounted on the fixed base 62. The elastic gripper 5 includes an elastic clamp 51, a push rod 52, and a first driving member 53. The elastic clamp 51 is used to fit onto and hold the insert 7, thereby completing the gripping action. The first driving member 53 is used to drive the push rod 52 to move until it contacts the insert 7, thereby causing the insert 7 to disengage from the elastic part 511, and finally completing the placement action. Through the cooperative use of the elastic clamp 51 and the push rod 52, the elastic gripper 5 can complete the gripping and placement of the insert 7 in one direction with only one power source, namely the first driving member 53. The structure is simple, saving costs and installation space.

[0034] The following combination Figure 3The elastic gripper 5 is further described below. The elastic gripper 5 also includes a sleeve 50, which has a through channel. The first end 501 of the sleeve 50 is fixed to the fixing base 62 by screws. The elastic clamp 51 passes through the through channel of the sleeve 50 and is at least partially exposed on the outside of the sleeve 50. Specifically, the elastic clamp 51 is integrally formed and includes an elastic part 511 and a fixing part 512 extending from the elastic part 511. The fixing part 512 passes through the sleeve 50 and is fixedly connected to the sleeve 50. The fixing method is not limited and can include welding, threaded connection, etc. The elastic part 511 is exposed on the outside of the sleeve 50 from the second end 502. The elastic part 511 is configured to be fitted onto the insert 7, and the insert 7 abuts against the inner wall of the elastic part 511. Understandably, the insert 7 tends to move downwards under the influence of gravity, while the elastic part 511 can generate the opposite frictional force on the insert 7 and has a circumferential clamping force, thereby enabling the elastic part 511 to grasp the insert 7.

[0035] Furthermore, an ejector cavity 510 is formed within the fixing part 512, and a push rod 52 is disposed within the ejector cavity 510. A first driving member 53 is fixed at the first end 501 near the sleeve 50, and the output end of the first driving member 53 is disposed within the ejector cavity 510 and can move along the length direction of the ejector cavity 510, thereby driving the push rod 52 to move along the length direction of the ejector cavity 510, ultimately enabling the push rod 52 to abut against the insert 7 and push the insert 7 to disengage from the elastic part 511, thereby completing the placement action of the insert 7.

[0036] To ensure that the elastic part 511 can apply sufficient clamping force to the insert 7, the elastic part 511 is designed to have a certain degree of elasticity and forms a gripping cavity 513, the diameter of which is smaller than the diameter of the insert 7. The insert 7 can be inserted into the gripping cavity 513, pressing the elastic part 511 outward. The inner wall of the elastic part 511 contracts inward under the elastic action, thereby creating pressure on the insert 7 from the inner wall forming the gripping cavity 513. This results in sufficient clamping force between the inner wall and the insert 7, thus gripping the insert 7. In this embodiment, the elastic part 511 is used to grip the insert 7, and the first driving member 53 pushes the insert 7 out. The gripping and placement of the insert 7 can be completed with only one power source and movement in one direction, avoiding the need for multiple power sources and multi-directional movements in traditional gripping structures to complete the gripping action of the insert 7. This reduces the size of the clamp and avoids bulkiness.

[0037] Preferably, the first driving component 53 can be a cylindrical cylinder, which helps to reduce the overall weight. At the same time, the cylindrical cylinder is coaxially arranged with the sleeve 50, which further optimizes the installation space and is suitable for confined environments.

[0038] Furthermore, to facilitate the elastic part 511's gripping of the insert 7, the elastic part 511 is multi-lobed, comprising multiple elastic spring pieces 51a. These spring pieces 51a enclose and form the aforementioned gripping cavity 513. The spring pieces 51a cooperate with each other to simultaneously clamp the insert 7, allowing the inner walls of the spring pieces 51a to hold the insert 7 in place. In this embodiment, the elastic clamp 51 is made of metal. Designing the elastic part 511 as multi-lobed effectively avoids stress concentration during gripping, improves the service life of the elastic clamp 51, and also facilitates the opening of the elastic part 511 when the insert 7 is inserted, increasing the gripping success rate.

[0039] In addition, the port 511a of the gripping cavity 513 is flared outwards to guide the insertion of the insert 7, thereby improving the fault tolerance during gripping.

[0040] Important reference Figure 2 The fixture also includes product grippers 6, which are used to grip the molded products inside the injection molding machine 1. The product grippers 6 are arranged along the X-axis. In this embodiment, the elastic gripper 5 includes a first elastic gripper 5Y arranged along the Y-axis and a second elastic gripper 5Z arranged along the Z-axis. The product grippers 6, the first elastic gripper 5Y, and the second elastic gripper 5Z are spatially offset, and the first elastic gripper 5Y and the second elastic gripper 5Z only move in their own gripping direction. This makes the structure of the product grippers 6, the first elastic gripper 5Y, and the second elastic gripper 5Z mounted on the fixed base 62 compact, and the three do not interfere with each other, resulting in a high degree of integration.

[0041] In this embodiment, the product gripper 6 includes a second driving member 60 and a pair of symmetrical clamps 61. Each clamp 61 has a first gripping portion 611 and a second gripping portion 612 arranged sequentially. The first gripping portion 611 is configured to engage with the first end of the injection-molded product, and the second gripping portion 612 is configured to engage with the second end of the product. The second driving member 60 is configured to drive the pair of clamps 61 to move away from or closer to each other along the X-axis to grip and prevent the product from being removed. Preferably, the second driving member 60 is a gripper cylinder, which has an adjustable and stable gripping force and a fast response speed.

[0042] Furthermore, this embodiment includes two feeding devices 2, which can supply inserts 7 of the same type or different types. The first elastic gripper 5Y and the second elastic gripper 5Z are used to grip and release the inserts 7 supplied by the two feeding devices 2, respectively. Simultaneously, two of each of the first elastic gripper 5Y and the second elastic gripper 5Z are provided on the same plane, thereby maximizing the use of the space in the fixing base 62. This allows the clamp in this embodiment to simultaneously handle up to four inserts 7, adapting to more needs and application scenarios.

[0043] Optional, see reference Figure 4 The feeding device 2 includes a vibrating material distribution mechanism 20 and a lifting mechanism 21. The vibrating material distribution mechanism 20 is configured to orderly convey multiple inserts 7 to the loading station, and the lifting mechanism 21 is configured to drive the inserts 7 located at the loading station to move to the clamping station. The vibrating material distribution mechanism 20 includes a vibrating plate 210, a guide block 211, and a guide drive 212. A guide groove 211a is formed on the guide block 211. A slide rail 213 is provided on the vibrating plate 210 and is connected to the guide groove 211a. The vibrating plate 210 allows a large number of disordered inserts 7 within the vibrating plate 210 to pass sequentially through the slide rail 213, thereby orderly conveying a large number of inserts 7 to the guide groove 211a. The output end of the guide drive 212 is configured to drive the inserts 7 located in the guide groove 211a to move along the guide groove 211a, thereby allowing multiple inserts 7 to be sequentially delivered to the lifting position. The aforementioned lifting mechanism 21 is installed below the lifting position. The lifting mechanism 21 consists of a fixed driving component and a push rod. The driving component can be a cylinder, a moving module, etc. The driving component drives the push rod to move vertically upward, thereby lifting the insert 7 located in the lifting position to the gripping station. At this time, the robot 4 has driven the gripper to move so that the elastic part 511 of one of the elastic clamps 51 is located in the gripping station. During the process of the lifting mechanism 21 lifting the insert 7 located in the lifting position to the gripping station, the insert 7 is gradually pushed into the gripping cavity 513 of the elastic part 511, thereby causing the insert 7 to be gripped.

[0044] Furthermore, to facilitate the detection of whether the elastic clamp 51 has moved into position, a detection sensor 22 is also provided on the feeding device 2. Only after the detection sensor 22 detects that the elastic clamp 51 has completed its positioning at the gripping station will the lifting mechanism 21 be activated to lift the insert 7, thus avoiding equipment malfunction and efficiency impact. The detection sensor 22 here is preferably a photoelectric sensor.

[0045] Optionally, the injection molding equipment also includes a gate shearing device 3 and a rotary transition mechanism 9. The gate shearing device 3, the rotary transition mechanism 9, and the feeding device 2 are mounted on the same platform and are all within the working range of the robot 4. After the robot 4 picks up enough inserts 7 at the gripping station, it moves to the position of the injection molding machine 1. At this time, the mold of the injection molding machine 1 opens, and the product gripper 6 first grips the first end of the product completed in the previous process and removes the product from the mold. Then, the inserts 7 are placed in the mold. Next, the robot 4 places the product in the gate shearing device 3, which cuts off a portion of the gate on the product. Then, the first gripping part 611 of the product gripper 6 grips the first end of the product and places the product on the rotary transition mechanism 9. After the rotary transition mechanism 9 flips the product from the first posture to the second posture, the second gripping part 612 of the product gripper 6 grips the second end of the product and places the product in the gate shearing device 3, which cuts off the other portion of the gate on the product. Finally, robot 4 delivers the product with the gate cut to the automatic packing mechanism 10, which then completes the packing of the product.

[0046] Optional, refer to Figure 1 The aforementioned automatic packing mechanism 10 has a box-separating station 101 and a loading station 102. The automatic packing mechanism 10 can separate multiple stacked boxes at the box-separating station 101, and then transport one of the boxes to the loading station 102. The robot 4 can place the product on the box located at the loading station 102. When the box is full, the automatic packing mechanism 10 can issue an alarm to remind the operator to remove the full box. Then, the automatic packing mechanism 10 will separate an empty box and transport it to the loading station 102.

[0047] Optionally, referring to Figure 5, the aforementioned rotary transition mechanism 9 includes a transition mechanism 90 and a rotary platform 91. The transition mechanism 90 has a placement platform 901 and a flipping groove 902. A first gripping part 611 grips the product and places it on the placement platform 901. At this time, a portion of the product's structure is fixedly limited within the flipping groove 902. Then, a second gripping part 612 grips the product and flips it 180°, placing the product on the rotary platform 91. The rotary platform 91 adaptively rotates and adjusts the product's position according to requirements until the desired position is met. This invention, through the cooperation of the rotary transition mechanism 9 and the robot 4, can easily complete the flipping of the product. It has a simple and reliable structure and occupies a small area.

[0048] In addition, the injection molding equipment also includes a product inspection mechanism 8, which is located next to the rotary transition mechanism 9. After the robot 4 takes out the product from the injection molding machine 1, it first places the product in the product inspection mechanism 8, which then checks whether the product has an insert 7. If not, the product is placed in the defective product box; if it does, the product is then subjected to gate trimming.

[0049] During operation, the operator first starts the injection molding equipment. At this time, the automatic packing mechanism 10, the feeding device 2, and the robot 4 are reset, and the injection molding machine 1 begins to run. The feeding device 2 transports the insert 7 to the loading station, while the robot 4 drives the fixture to move, causing the elastic gripper 51 to move to the gripping station. When the detection sensor 22 detects that the elastic gripper 51 has moved into position, the lifting mechanism 21 lifts the insert 7 from the loading station to the gripping station. During the process of the lifting mechanism 21 lifting the insert 7 from the lifting position to the gripping station, the insert 7 is gradually pushed into the gripping cavity 513 of the elastic part 511, thereby clamping the insert 7. The robot 4 then moves the fixture as needed to cause other elastic grippers 51 to also grip the corresponding insert 7, and then drives the fixture to move to the position of the injection molding machine 1, and ejects the insert 7 and places it in the mold of the injection molding machine 1. If there is a product in the mold of injection molding machine 1, gripper 6 first removes the product and then places insert 7 into the mold of injection molding machine 1. After placing insert 7 and retracting to a safe position, robot 4 sends a mold closing signal to injection molding machine 1, and injection molding machine 1 begins mold closing and injection. Then, robot 4 drives the fixture to move and places the product in product inspection mechanism 8, which checks whether the product has insert 7. If not, the product is placed in the defective product box. If it does, the product is conveyed to the gate shearing device 3 for the first gate shearing process. After the first gate shearing process, robot 4, in conjunction with the rotary transition mechanism 9, flips the product and sends it back to the gate shearing device 3 for the second gate shearing process. Finally, robot 4 transports the product to the unloading box located at the loading station 102 on the automatic packing mechanism 10.

[0050] This utility model innovatively uses an elastic gripper 5 with an elastic part 511 to grip the insert 7 and pushes the insert 7 out through the first drive 53. Only one power source is needed and the gripping and placement of the insert 7 can be completed in one direction, which greatly saves costs and installation space on the fixture. This allows multiple elastic grippers 5 to be installed on the fixture to meet more work needs.

[0051] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
