Description

Technical Field

[0001] This utility model relates to the field of assembly tooling technology, specifically to a tooling for insert installation and finished product removal in injection molds. Background Technology

[0002] In injection molding, insert installation and finished product removal are two critical steps. Traditional injection molds typically perform these two operations separately, which severely impacts production efficiency and product quality.

[0003] Traditional installation methods typically rely on manual operation or simple mechanical positioning devices. Manual installation of inserts is not only inefficient but also prone to errors due to human factors, affecting the quality and performance of the injection molded product. Existing mechanical positioning devices struggle to achieve high-precision positioning and stable delivery when installing inserts. For example, some devices cannot guarantee that the insert is accurately assembled into the designated position on the moving mold along a straight line, easily leading to problems such as insert jamming and misalignment. This can result in insert installation failure or mold damage, increasing production costs and equipment maintenance time.

[0004] Furthermore, the existing tooling and automated robotic arms have shortcomings in their coordination, whether for finished product handling or insert installation. The connection and positioning of many tooling components with the robotic arm are not precise enough. When the robotic arm grasps and moves the tooling, it cannot guarantee the accuracy of the tooling's posture and position, thus affecting the automation level and the stability of the entire production process. For example, when the robotic arm drives the tooling for insert installation, insufficient positioning accuracy at the connection between the tooling and the robotic arm may cause misalignment between the insert and the moving mold, affecting the yield rate of injection molded products.

[0005] In summary, existing tooling for insert installation and finished product removal in injection molds mainly requires multiple tooling operations. The replacement and hoisting of each tooling consumes a lot of time, especially for large injection molded parts, where tooling replacement takes even longer. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this utility model provides an insert installation and finished product removal tooling for injection molds, which can realize the installation of inserts and the removal of molded parts after injection molding in one process. This effectively improves the automation level of the injection molding production process, increases production efficiency, and reduces production costs.

[0007] This utility model achieves the above-mentioned technical objectives through the following technical means.

[0008] An insert mounting and finished product removal fixture for injection molds includes a finished product removal section, a gripping section, and an insert mounting section. The gripping section uses negative pressure to remove the finished product after injection molding. The gripping section is connected to a robotic arm for lifting and moving the fixture. The finished product removal section is connected to the insert mounting section, which includes a straight-line mechanism for installing several inserts into the injection mold.

[0009] Furthermore, the finished product picking unit includes a panel, a planar moving device, a connecting rod, and suction cups. The planar moving device is provided on the panel, and a plurality of suction cups are provided on the planar moving device. The suction cups are connected to the planar moving device through the connecting rod.

[0010] Furthermore, the finished product picking unit is equipped with a gripping part, and the gripping part has an interface on the outside that matches the robotic arm, so as to facilitate the connection between the robotic arm and the gripping part.

[0011] Furthermore, the insert mounting section includes a straight-moving mechanism and an insert assembly assembly; the straight-moving mechanism is located on the other side of the finished product taking-out section, and the insert is placed inside the insert assembly assembly. The insert in the insert assembly assembly is installed into the mold by the linear movement of the straight-moving mechanism.

[0012] Furthermore, the insert assembly includes a fixed plate, fixed posts, a movable plate, and insert mounting sleeves. The fixed plate is connected to the finished product taking part via several fixed posts. The movable plate is connected to the tension rod of the straight-line mechanism, and the tension rod passes through the fixed plate and connects to the movable plate. The tension rod causes the movable plate to move away from the fixed plate. Several insert mounting sleeves are evenly distributed on one side of the movable plate, and the installation position of the insert mounting sleeve matches the position of the insert installed in the fixed mold. The insert is placed inside the insert mounting sleeve. Several guide posts that match the insert mounting sleeve are provided on the fixed plate. One end of the guide post is connected to the fixed plate, and the other end of the guide post extends into the insert mounting sleeve and contacts the insert placed inside the insert mounting sleeve. The contraction of the tension rod causes the movable plate to move towards the fixed plate, and the guide posts push the insert inside the insert mounting sleeve to move outward.

[0013] Furthermore, a guide sleeve is installed inside the insert mounting sleeve, and the guide sleeve is a self-lubricating guide sleeve.

[0014] Furthermore, it also includes a positioning mechanism, which includes positioning pins symmetrically arranged on the movable plate. The positioning pins and the insert mounting sleeve are respectively arranged on one side of the movable plate, and the positioning pins cooperate with the positioning holes in the protrusions on the fixed mold.

[0015] Furthermore, the front end of the positioning pin is tapered, and the front end of the positioning hole is tapered.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. The insert installation and finished product removal tooling for injection molds described in this utility model can realize the installation of inserts and the gripping of molded parts after injection molding in one process, which effectively improves the automation level of injection molding production, increases production efficiency, and reduces production costs.

[0018] 2. The insert installation and finished product removal tooling for injection molds described in this utility model has suction cups with adjustable planar positions installed at the four ends of the panel.

[0020] 4. The insert installation and finished product removal fixture for injection molds described in this utility model achieves efficient and precise assembly of inserts through the insert installation section. The cylinder drive provides stable power, ensuring that the insert within the insert installation sleeve can move smoothly and accurately outwards and be installed in the corresponding position on the fixed mold, improving the efficiency and quality of insert installation.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] like Figure 1 As shown, the insert installation and finished product removal fixture for injection molds of this utility model includes a finished product removal part, a gripping part, and an insert installation part. The suction part uses negative pressure to remove the finished product after injection molding. The gripping part 2 is connected to the robotic arm 15 and is used to lift and move the fixture, facilitating the precise movement of the fixture. The finished product removal part is connected to the insert installation part, and the insert installation part is used to install several inserts into the injection mold.

[0031] like Figure 1 As shown, the finished product handling unit includes a panel 1, a horizontal guide rail 11, a vertical guide rail 12, a connecting rod 13, and a suction cup 14. The horizontal guide rail 11 is fixedly disposed on one side of the panel 1. There are at least two horizontal guide rails 11, and all horizontal guide rails 11 are arranged in parallel. At least two vertical guide rails 12 are installed in each horizontal guide rail 11 by a slider. The vertical guide rails 12 are arranged perpendicular to the horizontal guide rails 11. The vertical guide rails 12 can move back and forth horizontally along the horizontal guide rails 11 under the action of the slider. A strip-shaped groove is formed on the vertical guide rail 12 along the longitudinal direction. One end of the connecting rod 13 is disposed in the strip-shaped groove. The connecting rod 13 can move in the strip-shaped groove. The other end of the connecting rod 13 is provided with a suction cup 14. That is, suction cups 14 with adjustable planar positions are installed at the four ends of panel 1. The suction cups 14 can adhere to the finished product after injection molding. The position of the suction cups 14 can be adjusted according to the shape of the finished product after injection molding. After the position is adjusted, they are fixed by fasteners. In the impeller injection mold of the embodiment, the finished product after injection molding is located in the moving mold.

[0032] like Figure 1 As shown, a gripping part 2 is provided on the other side of the panel 1. The gripping part 2 has an interface that matches the robotic arm 15, which facilitates a stable connection between the robotic arm 15 and the gripping part 2. Figure 2 As shown, the robotic arm 15 is mounted on a cantilever crane, and the end of the robotic arm 15 is a mechanical claw. The gripping part 2 has a groove on the outside that matches the mechanical claw. The precise movement of the robotic arm 15 ensures accurate positioning of the tooling.

[0033] like Figure 1As shown, the insert mounting part includes a cylinder 3, a positioning mechanism, and an insert assembly assembly. The cylinder 3 is located on the other side of the panel 1; in this embodiment, the cylinder 3 is mounted on one side of the gripping part 2. The insert assembly assembly includes a fixed plate 5, fixed posts 6, a movable plate 7, and insert mounting sleeves 9. The fixed plate 5 is fixedly connected to the panel 1 by several fixed posts 6 of equal length. The movable plate 7 is connected to the tension rod 4 of the cylinder 3, and the tension rod 4 passes through the fixed plate 5 and connects to the movable plate 7. The tension rod 4 causes the movable plate 7 to move away from the panel 1. Several insert mounting sleeves 9 are evenly distributed on one side of the movable plate 7, and the installation position of the insert mounting sleeves 9 matches the position of the insert mounted on the fixed mold. The insert is placed inside the insert mounting sleeve 9. Several guide posts 8 are provided on the fixed plate 5 to match the insert mounting sleeves 9. One end of the guide post 8 is connected to the fixed plate 5, and the other end of the guide post 8 extends into the insert mounting sleeve 9, so as to contact the insert placed inside the insert mounting sleeve 9. By retracting the tension rod 4 of cylinder 3, the movable plate 7 moves towards the fixed plate 5. The guide post 8, mounted on the fixed plate 5, remains stationary. Therefore, the movement of the movable plate 7 towards the fixed plate 5 is equivalent to the guide post 8 pushing the insert inside the insert mounting sleeve 9 outward, thus completing the insert assembly. Of course, before the insert moves outward, the positioning mechanism needs to cooperate with the fixed mold.

[0034] To ensure that the guide post 8 moves linearly within the insert mounting sleeve 9, a guide sleeve is installed inside the insert mounting sleeve 9. The guide sleeve is a self-lubricating guide sleeve.

[0035] The positioning mechanism is used for precise positioning of the assembly tooling and the fixed mold. The positioning mechanism includes positioning pins 10 symmetrically arranged on the movable plate 7. The positioning pins 10 and insert mounting sleeves 9 are respectively located on one side of the movable plate 7. The positioning pins 10 engage with positioning holes in the protrusions on the fixed mold, thus the positioning pins 10 engage with the fixed mold first. The front end of the positioning pin 10 is tapered, and the front end of the positioning hole is also tapered, which serves as a guide for precise positioning.

[0036] The insert mounting and finished product removal fixture for injection molds described in this utility model has an insert mounting section at one end for mounting inserts into the mold, and a finished product removal section at the other end for removing the finished product. The working process is as follows:

[0037] After one injection molding cycle, the moving mold and the fixed mold separate; the insert is placed in the insert mounting sleeve 9 of the tooling. Using the robotic arm 15 connected to the gripper 2, the robotic arm 15 is moved to position the tooling between the moving and fixed molds, at which point the panel 1 is approximately perpendicular to the mold opening direction. Then, the robotic arm 15 is precisely controlled to move, aligning the locating pin 10 with the locating hole. The tooling is then translated using the robotic arm 15. Since the front end of the locating pin 10 is tapered, and the front end of the locating hole is tapered, it acts as a guide, facilitating precise positioning of the locating pin 10 and the locating hole during the parallel process. After positioning, the robotic arm 15 continues to translate the tooling until the insert mounting sleeve 9 is in place. The extension rod 4 of the drive cylinder retracts, causing the movable plate 7 to move towards the fixed plate 5, which in turn pushes the insert inside the insert mounting sleeve 9 outwards, completing the insert assembly. The insert is installed for use in the next injection molding cycle. The insert is sleeve-shaped, and the fixed mold contains a matching pin core.

[0038] The robotic arm 15 moves the fixture in the reverse direction, disengaging the locating pin 10 from the locating hole on the fixed mold. Then, the robotic arm 15 continues to move in the reverse direction, bringing the suction cup 14 into contact with the surface of the injection-molded product. The suction cup is then activated, achieving a tight adhesion between the suction cup 14 and the injection-molded product. The movement of the robotic arm 15 is then used to move the injection-molded product to the next process.

[0039] It should be understood that although this specification is described according to various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0040] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. All equivalent embodiments or modifications made without departing from the spirit of the present utility model should be included within the scope of protection of the present utility model.
