Description

Technical Field

[0001] This invention relates to the field of mechanical automation, and more particularly to a device for removing injection molded parts. Background Technology

[0002] Currently, product manufacturing typically involves injection molding. After the upper and lower molds of an injection mold are tightly fitted together, the molded part is injected through the injection runner between them. Once the injection molding process is complete, the upper and lower molds are separated, and the molded part located between them is removed.

[0003] Currently, after injection molding is completed, there are automated devices that can disassemble the upper and lower molds of the injection mold and remove the injection molded parts.

[0004] However, existing injection molded part removal devices have complex structures and many parts, and after the injection molded part is removed, the upper and lower molds of the injection mold cannot be re-engaged. Summary of the Invention

[0005] The purpose of this invention is to provide an injection molded part removal device that enables automatic removal of the injection molded part and automatic engagement of the upper and lower molds of the injection mold.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] An injection molded part removal device is used to remove an injection molded part located between an upper mold and a lower mold, wherein the upper mold and the lower mold are mutually capped to form an injection mold. The upper mold has an injection runner, and the injection runner is provided with a plug to close the injection runner. The device includes a plug removal flow line for transporting the injection mold, a plug removal robot located above the plug removal flow line, an injection mold disassembly platform, a first robot for transferring the injection mold after plug removal to the injection mold disassembly platform, and a second robot located above the injection mold disassembly platform. The second robot cooperates with the injection mold disassembly platform to separate the upper mold, the injection molded part, and the lower mold from each other. Simultaneously, the second robot cooperates with the injection mold disassembly platform to cap the upper mold and the lower mold, and the injection mold and the separated injection molded part are both located on the injection mold disassembly platform. The device also includes a third robot for transferring the injection molded part located on the injection mold disassembly platform to an external mechanism and a fourth robot for transferring the injection mold located on the injection mold disassembly platform to an external mechanism.

[0008] Furthermore, the injection mold disassembly platform includes a lower mold fixing platform and a suction fixing platform. The second robotic arm is used to clamp the upper mold. The first robotic arm transfers the injection mold with the plug removed to the lower mold fixing platform. While the lower mold fixing platform fixes the lower mold, the second robotic arm clamps the upper mold and moves it away from the lower mold, separating the upper mold and the injection molded part from the lower mold. Subsequently, the second robotic arm places the upper mold and the injection molded part on the suction fixing platform. The suction fixing platform includes a suction cup that adsorbs the injection molded part. The second robotic arm clamps the upper mold and moves it away from the suction cup, separating the injection molded part from the upper mold. Subsequently, the second robotic arm covers the lower mold with the upper mold.

[0009] Furthermore, the injection mold disassembly platform is reciprocating, and the second robot arm is positioned above the motion trajectory of the injection mold disassembly platform; the second robot arm includes an upper mold gripper and an upper mold gripper drive mechanism that drives the upper mold gripper to move along the height direction; when the upper mold and the injection molded part are separated from the lower mold, the lower mold fixing platform is located below the second robot arm; when the injection molded part is separated from the upper mold, the adsorption fixing platform is located below the second robot arm.

[0010] Furthermore, the second robotic arm is equipped with a blow molding mechanism; while the second robotic arm grips the upper mold, the blow molding mechanism enters the injection runner; after the upper mold and the injection molded part are separated from the lower mold, the blow molding mechanism blows air toward the injection runner.

[0011] Furthermore, the lower mold includes a lower mold body and a latch disposed on the lower mold body. The lower mold body and the upper mold cooperate to form an injection mold. The latch has a first position and a second position. When the latch is in the first position, the latch is separated from the upper mold. When the latch is in the second position, the latch is engaged on the surface of the upper mold away from the lower mold body.

[0012] Furthermore, the first robotic arm includes a pair of injection mold grippers and a pair of locking claws. The injection mold grippers and the locking claws can move closer to each other or further away from each other. When the injection mold grippers move closer to each other, the upper mold and the lower mold body are clamped simultaneously. When the locking claws move further away from each other, the locking claws change the locking position from the second position to the first position.

[0013] Furthermore, the lower mold fixing platform is provided with a locking fastener and a locking fastening drive mechanism for driving the locking fastener to move; the movement of the locking fastener is used to change the lock from the first position to the second position.

[0014] Furthermore, a plug removal detection device is provided on one side of the plug removal flow line. The plug removal detection device is located below the plug removal robot. The plug removal robot includes a plug removal claw and a plug removal claw drive mechanism for driving the plug removal claw to move. The plug removal claw is used to clamp the plug. After the plug removal claw drive mechanism drives the plug removal claw to clamp the plug that closes the injection channel opening, the plug removal claw drive mechanism drives the plug removal claw to move the plug to above the plug removal detection device. The plug removal detection device is used to detect whether the plug is clamped on the plug removal claw.

[0015] Furthermore, it includes an NG unloading platform; when the plug removal detection device detects that the plug is not held on the plug removal claw, the first robot arm transfers the injection mold with the plug still attached, located on the plug removal flow line, to the NG unloading platform.

[0016] Furthermore, the plug-out flow line is provided with a blocking mechanism that can block the movement of the injection mold.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up an injection mold disassembly platform and a second robotic arm positioned above the injection mold disassembly platform, and by cooperating with the injection mold disassembly platform, the upper mold, the injection molded part, and the lower mold can be separated from each other. Furthermore, by cooperating with the injection mold disassembly platform, the upper mold and the lower mold can be closed together. This allows for the automatic removal of the injection molded part while simultaneously achieving the automatic locking of the upper and lower molds of the injection mold. The entire injection molded part removal device has a simple structure and a high degree of automation. Attached Figure Description

Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0037] like Figures 1 to 6 As shown, this invention discloses an injection molded part removal device. In the production process of the preceding automated device of the injection molded part removal device, an upper mold 1 is fitted onto a lower mold 2 to form an injection mold. The upper mold 1 is provided with an injection runner 1a. An injection molding machine injects material into the injection mold through the injection runner 1a. After injection is completed, a plug 1b is used to seal the injection runner 1a. After the injection mold is photocured, the photocured injection mold enters the injection molded part removal device of this invention via a conveying device. The injection molded part removal device of this invention is used to remove the injection molded part located between the upper mold 1 and the lower mold 2.

[0038] like Figures 1 to 9 As shown in detail, the injection molded part removal device of the present invention includes a plug removal flow line 3 for transporting the injection mold, a plug removal robot 4 located above the plug removal flow line 3, an injection mold disassembly platform 5, a first robot 6 for transferring the injection mold after plug removal to the injection mold disassembly platform 5, and a second robot 7 disposed above the injection mold disassembly platform 5.

[0039] The injection mold, after photocuring, enters the plug removal flow line 3 via a conveyor device, where the plug removal robot 4 removes the plug 1b located on the upper mold 1. Subsequently, the first robot 6 transfers the plug-removed injection mold to the injection mold disassembly platform 5. The second robot 7, in cooperation with the injection mold disassembly platform 5, separates the upper mold 1, the injection molded part, and the lower mold 2. Simultaneously, the second robot 7, in cooperation with the injection mold disassembly platform 5, closes the upper mold 1 and the lower mold 2 together, at which point the injection mold contains no injection molded part. Both the injection mold without the injection molded part and the separated injection molded part are then placed on the injection mold disassembly platform 5.

[0040] The injection molded part removal device of the present invention further includes a third robot 8 for transferring the injection molded part located on the injection mold removal platform 5 to an external mechanism, and a fourth robot 9 for transferring the injection mold located on the injection mold removal platform 5 to an external mechanism. That is, after the injection molded part is removed, the third robot 8 transfers the injection molded part from the injection mold removal platform 5 to another device. After the upper mold 1 and the lower mold 2 are re-engaged to form the injection mold, the fourth robot 9 transfers the injection mold from the injection mold removal platform 5 to another device.

[0041] This invention utilizes a mold removal platform 5 and a second robotic arm 7 positioned above it. The second robotic arm 7, in conjunction with the mold removal platform 5, allows the upper mold 1, the molded part, and the lower mold 2 to be separated. Furthermore, the second robotic arm 7, also in conjunction with the mold removal platform 5, allows the upper mold 1 and the lower mold 2 to be closed together. This enables automatic removal of the molded part while simultaneously and automatically closing the upper mold 1 and the lower mold 2. The entire molded part removal device has a simple structure and a high degree of automation.

[0042] In this embodiment, as Figures 3 to 5 , Figures 10 to 13 As shown, the injection mold disassembly platform 5 includes a lower mold fixing platform 5a and an adsorption fixing platform 5b, and the second robotic arm 7 is used to clamp the upper mold 1. Figure 5 As shown, the first robotic arm 6 transfers the injection mold with the plug removed to the lower mold fixing platform 5a. Figure 3 , Figure 5 and Figure 13As shown, the lower mold fixing platform 5a is equipped with a lower mold fixing mechanism to fix the lower mold 2. While the lower mold fixing platform 5a fixes the lower mold 2, the second robotic arm 7 clamps the upper mold 1 and moves it away from the lower mold 2, thus separating the upper mold 1 and the injection molded part from the lower mold 2. Figure 3 , Figure 10 , Figure 11 and Figure 13 As shown, the second robotic arm 7 then places the upper mold 1 along with the injection molded part onto the adsorption and fixing platform 5b. The adsorption and fixing platform 5b includes a suction cup 5ba, which adsorbs the injection molded part. The upper mold 1, the injection molded part, and the adsorption and fixing platform 5b are arranged sequentially from high to low along the height direction. The second robotic arm 7 grips the upper mold 1 and moves it away from the suction cup 5ba, separating the injection molded part from the upper mold 1. Subsequently, the second robotic arm 7 covers the lower mold 2 with the upper mold 1. At this time, because the injection molded part is located on the adsorption and fixing platform 5b, the upper mold 1 and lower mold 2, which are mutually covering each other on the lower mold fixing platform 5a, do not contain the injection molded part. In other embodiments, the injection mold disassembly platform 5 may only be used to fix the upper mold 1, and the second robotic arm 7 may include a lower mold gripper for gripping the lower mold 2 and an injection molded part suction cup for adsorbing the injection molded part. When the first robotic arm 6 transfers the injection mold with the plug removed to the injection mold disassembly platform 5, the upper mold 1 is placed on the injection mold disassembly platform 5. After the injection mold disassembly platform 5 fixes the upper mold 1, the lower mold gripper clamps the lower mold 2 and moves it away from the upper mold 1, separating the lower mold 2 from the upper mold 1. At this time, the injection molded part is still attached to the upper mold 1. Subsequently, the injection molded part suction cup adsorbs the injection molded part and moves it away from the upper mold 1, separating the injection molded part from the upper mold 1. Then, the lower mold gripper latches the lower mold 2 onto the upper mold 1.

[0043] In this embodiment, as Figures 1 to 4 , Figure 7 and Figure 13As shown, the injection mold removal platform 5 is reciprocating. Specifically, the injection mold removal platform 5 can reciprocate along the X-axis under the action of the injection mold removal platform drive device. The injection mold removal platform drive device includes an injection mold removal platform slide rail arranged along the X-axis, the injection mold removal platform 5 is mounted on the injection mold removal platform slide rail, and the injection mold removal platform drive device also includes an injection mold removal platform drive motor that drives the injection mold removal platform 5 to reciprocate along the injection mold removal platform slide rail. Because the injection mold removal platform 5 includes the lower mold fixing platform 5a and the suction fixing platform 5b, the lower mold fixing platform 5a and the suction fixing platform 5b can also reciprocate along the X-axis. The second robotic arm 7 is positioned above the movement trajectory of the injection mold removal platform 5, that is, the second robotic arm 7 is positioned above the injection mold removal platform slide rail. Figure 3 and Figure 13As shown, the second robotic arm 7 includes an upper mold gripper 7a and an upper mold gripper drive mechanism 7b that drives the upper mold gripper 7a to move along the height direction. The upper mold gripper drive mechanism 7b includes an upper mold gripper slide rail arranged along the Z-axis direction, and the upper mold gripper 7a can slide on the upper mold gripper slide rail. The upper mold gripper drive mechanism 7b also includes an upper mold gripper drive motor that drives the upper mold gripper 7a to slide. The upper mold grippers 7a are arranged in pairs, with two upper mold grippers 7a forming a pair. The paired upper mold grippers can move closer to each other or further away from each other along the X-axis direction. When the upper mold gripper 7a grips the upper mold 1, the two upper mold grippers 7a move closer to each other, thereby gripping the upper mold 1. The first robotic arm 6 transfers the injection mold with the plug removed to the lower mold fixing platform 5a. After the lower mold fixing mechanism fixes the lower mold 2, the lower mold fixing platform 5a moves to directly below the second robotic arm 7 under the drive of the injection mold disassembly platform drive motor. Subsequently, the upper mold gripper drive motor drives the paired upper mold grippers 7a to descend. When the upper mold grippers 7a descend to be level with the upper mold 1 located on the lower mold fixing platform 5a in the height direction, the paired upper mold grippers 7a move closer together, realizing the second robot arm 7 gripping the upper mold 1. Subsequently, driven by the upper mold gripper drive motor, the upper mold grippers 7a, holding the upper mold 1 and the injection molded part, rise together, realizing the separation of the upper mold 1 and the injection molded part from the lower mold 2. Subsequently, driven by the injection mold disassembly platform drive motor, the suction fixing platform 5b moves to directly below the second robot arm 7. Subsequently, the upper mold gripper drive motor drives the paired upper mold grippers 7a to descend until the injection molded part held by the upper mold grippers 7a is suctioned by the suction cup 5ba. Subsequently, the upper mold gripper drive motor drives the paired upper mold grippers 7a to rise, separating the injection molded part from the upper mold 1. Subsequently, driven by the injection mold disassembly platform drive motor, the lower mold fixing platform 5a moves to directly below the second robot arm 7. The upper mold gripper drive motor drives the paired upper mold grippers 7a to descend until the upper mold 1 covers the lower mold 2, after which the paired upper mold grippers 7a move away from each other. Then, driven by the upper mold gripper drive motor, the paired upper mold grippers 7a rise again. In other embodiments, the second robot arm 7 can be configured to reciprocate along the X and Z axes, while the injection mold disassembly platform 5 remains stationary.

[0044] In this embodiment, as Figure 13As shown, to facilitate the separation of the injection molded part from the upper mold 1, the second robotic arm 7 is equipped with a blow molding mechanism 10. While the second robotic arm 7 grips the upper mold 1, the blow molding mechanism enters the injection runner 1a. After the upper mold 1, along with the injection molded part, separates from the lower mold 2, the blow molding mechanism 10 blows air towards the injection runner 1a. Through the blow molding mechanism 10, this invention allows air to be blown towards the injection runner 1a, and the blown airflow travels through the injection runner to the injection molded part, causing the injection molded part to loosen relative to the upper mold 1. This facilitates the separation of the injection molded part from the upper mold 1 when the injection molded part is attracted by the suction cup 5ba and the upper mold 1 is gripped by the second robotic arm 7.

[0045] In this embodiment, as Figure 5 As shown, the lower mold 2 includes a lower mold body 2a and a latch 2b disposed on the lower mold body 2a. The latches 2b are arranged in pairs on opposite sides of the lower mold body 2a. The lower mold body 2a and the upper mold 1 cooperate to form an injection mold. The latches 2b have a first position and a second position. When the latches 2b are in the first position, they are separated from the upper mold 1, allowing the upper mold 1 to be separated from the lower mold 2, and the injection molded part can then be removed. When the latches 2b are in the second position, they are engaged on the surface of the upper mold 1 away from the lower mold body 2a. Due to the engagement of the latches 2b, the upper mold 1 can be tightly fitted to the lower mold 2, allowing injection molding to be performed through the injection runner 1a. In other embodiments, the latches 2b can also be disposed on the upper mold 1, or other locking devices can be used to lock the upper mold 1 and the lower mold 2.

[0046] In this embodiment, as Figure 7 , Figure 8 and Figure 14As shown, the first robotic arm 6 includes a gripping assembly 6a and a gripping assembly drive mechanism 6b that drives the gripping assembly 6a to move along the Y-axis and Z-axis directions. The plug-removing streamline 3 is located below the movement trajectory of the gripping assembly 6a along the Y-axis, and the movement trajectory of the injection mold disassembly platform 5 is also located below the movement trajectory of the gripping assembly 6a along the Y-axis. Furthermore, the movement trajectories of the injection mold and the injection mold disassembly platform 5 in the plug-removing streamline 3 are parallel to each other, and both movement trajectories are set along the X-axis direction. The gripping assembly 6a includes a pair of injection mold grippers 6aa and a pair of locking claws 6ab, which can move closer to or further away from each other. The gripping assembly 6a also includes an injection mold gripper drive mechanism that drives the injection mold grippers 6aa and a locking claw drive mechanism that drives the locking claws 6ab. When the injection mold with the plug removed needs to be transferred to the lower mold fixing platform 5a, the clamping component drive mechanism 6b drives the clamping component 6a to move above the plug removal streamline 3. Then, the clamping component drive mechanism 6b drives the clamping component 6a to descend, and the injection mold jaw drive mechanism drives the injection mold jaws 6aa to move closer together, simultaneously clamping the upper mold 1 and the lower mold body 2a. Subsequently, driven by the clamping component drive mechanism 6b, the injection mold is clamped onto the lower mold fixing platform 5a. The lower mold fixing platform 5a is provided with a positioning pin, and the lower mold body 2a is provided with a positioning hole that mates with the positioning pin. Before the injection mold jaws 6aa clamp the injection mold, the locking claws 6ab move closer together under the drive of the locking claw drive mechanism, so that after the injection mold jaws 6aa clamp the injection mold, the locking claws 6ab are located between the paired locking claws 2b. When the first robotic arm 6 clamps the injection mold onto the lower mold fixing platform 5a, the locking claw driving mechanism drives the locking claws 6ab to move away from each other. The locking claws 6ab that are moving away from each other contact the locking claw 2b, causing the locking claw 2b to leave the upper mold 1. The locking claw 2b changes from the second position to the first position, so that the second robotic arm 7 can clamp the upper mold 1 and separate the upper mold 1 together with the injection molded part from the lower mold 2.

[0047] In this embodiment, as Figure 8As shown, the third robotic arm 8 has the same structure as the first robotic arm 6. After the injection molded part is removed from the injection mold, the lower mold fixing mechanism releases the fixing of the lower mold 2, and the lower mold fixing platform 5a moves to directly below the third robotic arm 8. The third robotic arm 8 grasps the closed injection mold from the lower mold fixing platform 5a and transfers the injection mold to the mold recycling flow line, which is located below the movement trajectory of the clamping assembly 6a along the Y-axis.

[0048] In this embodiment, as Figure 9 As shown, the fourth robotic arm 9 includes an injection molded part suction cup and an injection molded part suction cup drive mechanism that drives the injection molded part suction cup to move along the Y-axis and Z-axis directions. The motion trajectory of the injection mold disassembly platform 5 is located below the motion trajectory of the suction cup drive mechanism along the Y-axis direction. After the injection molded part suction cup adsorbs the injection molded part, it is transferred into the injection molded part flow line under the drive of the injection molded part suction cup drive mechanism.

[0049] In this embodiment, as Figure 4 and Figure 5 As shown, the lower mold fixing platform 5a is provided with a locking fastener 5c and a locking fastening drive mechanism that drives the locking fastener 5c to move. Under the drive of the locking fastening drive mechanism, the locking fastener 5c can reciprocate along the Z-axis. When the locking claw 6ab moves the locking buckle 2b from the second position to the first position, the locking fastener 5c descends along the Z-axis, and the locking buckle 2b falls onto the locking fastener 5c due to its own gravity. After the injection molded part is removed and the upper mold 1 is placed on the lower mold body 2a, the locking fastener 5c rises along the Z-axis, causing the locking buckle 2b to engage with the surface of the upper mold 1 away from the lower mold body 2a, and the locking buckle 2b changes from the first position to the second position.

[0050] In this embodiment, as Figure 1 and Figure 5As shown, a plug removal detection device 11 is provided on one side of the plug removal flow line 3. The plug removal detection device 11 is located below the plug removal robot 4. The plug removal robot 4 includes a plug removal claw 4a and a plug removal claw drive mechanism that drives the plug removal claw 4a to move. The plug removal claw 4a is used to grip the plug. After the plug removal claw drive mechanism drives the plug removal claw 4a to grip the plug 1b that closes the injection molding flow channel, the plug removal claw drive mechanism drives the plug removal claw 4a to move above the plug removal detection device 11. The plug removal detection device 11 is a camera that takes pictures of the plug removal claw 4a. The plug removal detection device 11 is used to detect whether the plug is gripped on the plug removal claw 4a. This invention, through the setting of the plug removal detection device 11, can detect whether the plug removal robot 4 is working properly.

[0051] In this embodiment, the injection molded part removal device of the present invention further includes an NG unloading platform. When the plug removal detection device 11 detects that the plug 1b is not held on the plug removal claw 4a, the first robotic arm 6 transfers the injection mold with the plug still attached, located on the plug removal flow line 3, to the NG unloading platform.

[0052] In this embodiment, the plug removal flow line 3 is provided with a blocking mechanism that can block the movement of the injection mold. When the first robot 6 transfers the injection mold to the injection mold disassembly platform 5, the blocking mechanism can block the injection mold from moving on the plug removal flow line 3, making it easier for the first robot 6 to grip the injection mold.

[0053] In summary, this invention, by setting up the injection mold disassembly platform 5 and a second robotic arm 7 above the injection mold disassembly platform, and by cooperating with the injection mold disassembly platform 5, allows the upper mold 1, the injection molded part, and the lower mold 2 to be separated from each other. Furthermore, by cooperating with the injection mold disassembly platform 5, the upper mold 1 and the lower mold 2 can be closed together. This enables automatic removal of the injection molded part while simultaneously achieving automatic locking of the upper mold 1 and the lower mold 2. The entire injection molded part removal device has a simple structure and a high degree of automation. Furthermore, by setting up the blow molding mechanism 10, air can be blown through the injection runner 1a, and the blown airflow is directed onto the injection molded part, causing the injection molded part to loosen relative to the upper mold 1. This facilitates the separation of the injection molded part from the upper mold 1 when the injection molded part is attracted by the suction cup 5ba and the upper mold 1 is clamped by the second robotic arm 7. The plug removal detection device 11 can be used to detect whether the plug removal robot 4 is working properly.

[0054] It should be emphasized that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
