Description

Technical Field

[0001] This utility model belongs to the field of manufacturing technology, specifically a part loading and unloading device for an injection molding machine. Background Technology

[0002] Injection molding machines can complete large-scale production in a short time. The injection molding process is relatively fast. From heating and injection to cooling and molding, the entire cycle can be completed in tens of seconds to minutes. The part pick-and-place device can quickly and automatically remove the injection molded parts from the mold after injection molding and place them in the designated position. This greatly shortens the production cycle and avoids the waste of time that would otherwise be spent manually picking and placing parts.

[0003] The part-loading device of the injection molding machine uses a robotic arm to remove the cooled injection molded parts from the mold and place them in a designated position. The entire process is coordinated by the automatic control system. The part-loading device of the injection molding machine can efficiently pick up and place the injection molded parts produced, providing strong support for the transportation of injection molded parts.

[0004] Most existing part-picking and placing devices use robotic arms or electric slide rails to move the part-picking and placing device, thereby moving the injection molded part. However, in some single, short-distance scenarios, robotic arms and electric slide rails require too many steps to transport the injection molded part due to their complex structure, which affects the efficiency of picking up and placing the injection molded part. Therefore, a part-picking and placing device for injection molding machines is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, most existing pick-and-place devices use robotic arms or electric slide rails to move the pick-and-place device and thus move the injection molded parts. However, in some single, short-distance scenarios, robotic arms and electric slide rails require too many steps to transport the injection molded parts due to their complex structure, which affects the efficiency of picking and placing injection molded parts. This utility model proposes a pick-and-place device for injection molding machines.

[0006] The technical solution adopted by this utility model to solve its technical problem is a part loading and unloading device for an injection molding machine, including a working platform. The main body of the injection molding machine is installed at one top end of the working platform. An injection platform is located below the main body of the injection molding machine. The bottom of the injection platform is fixedly installed at the top of the working platform. An injection mold is fixedly installed at the top of the injection platform. A support block is fixedly installed at the other top end of the working platform. A sliding groove is formed inside the support block. An electric slide rail is fixedly installed inside the sliding groove. A sliding block is slidably installed outside the electric slide rail. Multiple limiting plates are fixedly installed on one side of the sliding block. A connecting plate is tightly attached between the multiple limiting plates. A rotating cylinder is fixedly installed at the bottom of the connecting plate. Both the connecting plate and the rotating cylinder rotate internally. A connecting rod is installed, with one end of the connecting rod fixedly mounted on the top of the work platform. A limiting groove is formed on one side of the inside of the rotating cylinder, and a limiting rod is tightly attached to the inside of the limiting groove. A fixing plate is fixedly mounted on the end of the limiting rod away from the limiting groove, and the bottom of the fixing plate is fixedly mounted on the top of the work platform. A rotating plate is fixedly mounted on the outside of the rotating cylinder. The rotating cylinder is driven to move up and down by an electric slide rail. When the rotating cylinder moves up and down, the arc-shaped limiting groove connects with the limiting rod, causing the rotating cylinder to move up and down while rotating left and right. The simultaneous up-and-down movement and left-and-right rotation of the rotating cylinder causes the suction cup to rotate to another position after adsorbing the injection molded part, so as to unload the injection molded part. The rotating cylinder drives the suction cup to rotate left and right, achieving a more convenient and efficient effect of picking up and placing injection molded parts.

[0007] Preferably, a support plate is fixedly installed on one side of the bottom of the rotating plate, a vacuum distributor is fixedly installed on the bottom of the support plate, a vacuum pump is installed on the top of the support plate, an air supply pipe is fixedly installed at the input end of the vacuum pump, and the end of the air supply pipe away from the vacuum pump is fixedly installed inside the vacuum distributor. Multiple suction cups are fixedly installed inside the vacuum distributor. After the vacuum pump is started, it will draw air from inside the vacuum distributor to create a low-pressure environment. At this time, the multiple suction cups at the bottom of the vacuum distributor are connected to the pipeline system of the vacuum distributor to adsorb the externally molded parts.

[0008] Preferably, a first fixing block is fixedly installed on all four sides of the injection mold. A connecting groove is opened inside each of the first fixing blocks. An installation rod is slidably installed inside the connecting groove. A fixing rod is provided on the outside of the end of the installation rod away from the first fixing block. A second fixing block is fixedly installed on the top of the fixing rod. The sides of the second fixing blocks are fixedly installed on the four ends of the vacuum distributor. The installation rod is connected to the connecting groove opened inside the first fixing block, so as to make the position more accurate and consistent when the injection molded part is taken out.

[0009] Preferably, each of the plurality of fixing rods has an opening inside, and a spring is fixedly installed inside the opening. One end of the spring is fixedly installed at the bottom of the second fixing block, and the other end of the spring is fixedly installed at the top of the mounting rod. When the vacuum distributor comes into contact with the injection mold, the spring inside the fixing rod can buffer the impact force generated, preventing the multiple suction cups from directly contacting the injection mold.

[0010] Preferably, a control panel is fixedly installed on the top of the work platform. The control panel is electrically connected to the electric slide rail and the vacuum pump. The electric slide rail and the vacuum pump are controlled through the control panel, making it more convenient to operate the process of picking up and placing injection molded parts.

[0011] Preferably, the top of the work platform is provided with a collection box, which is located below multiple suction cups, and the finished injection molded parts can be collected through the collection box.

[0012] The advantages of this utility model are:

[0013] This invention addresses the problem that existing part-picking and placing devices, which mostly rely on robotic arms or electric slide rails to move the part-picking and placing mechanism, require numerous steps to transport the part in short-distance scenarios, thus affecting efficiency. By using a rotating cylinder to drive the suction cup to rotate left and right during the production of injection molded parts, this invention achieves a more convenient and efficient part-picking and placing effect.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5As shown, a part-loading device for an injection molding machine includes a work platform 1. An injection molding machine body 15 is mounted on the top of the work platform 1. An injection molding platform 22 is located below the injection molding machine body 15. The bottom of the injection molding platform 22 is fixedly mounted on the top of the work platform 1. An injection mold 23 is fixedly mounted on the top of the injection molding platform 22. A support block 2 is fixedly mounted on the other top of the work platform 1. A sliding groove 3 is formed inside the support block 2. An electric slide rail 4 is fixedly mounted inside the sliding groove 3. A sliding block 5 is slidably mounted on the outside of the electric slide rail 4. Multiple limiting plates 6 are fixedly mounted on one side of the outer side of the sliding block 5. A connecting plate 7 is tightly attached between the limiting plates 6. A rotating cylinder 8 is fixedly installed at the bottom of the connecting plate 7. A connecting rod 10 is rotatably installed inside both the connecting plate 7 and the rotating cylinder 8. One end of the connecting rod 10 is fixedly installed at the bottom of the top of the working platform 1. A limiting groove 9 is formed on one side of the inside of the rotating cylinder 8. A limiting rod 12 is tightly attached inside the limiting groove 9. A fixing plate 11 is fixedly installed at the end of the limiting rod 12 away from the limiting groove 9. The bottom of the fixing plate 11 is fixedly installed at the top of the working platform 1. A rotating plate 16 is fixedly installed on the outside of the rotating cylinder 8. During operation, the existing part-picking and placing device has a complex structure and too many steps. When picking up and placing injection molded parts along a single path and over a short distance, the excessive steps in the picking and placing device lead to inefficiencies. To improve efficiency, this device activates an electric slide rail 4 to move a sliding block 5 up and down. This movement of the sliding block 5 causes multiple side-mounted limiting plates 6 to move up and down, which in turn causes connecting plates 7 to move up and down. This movement of the connecting plates 7, in turn, causes a rotating cylinder 8 to move up and down. As the rotating cylinder 8 moves, its internal limiting groove 9 connects to one end of a limiting rod 12, further driving the rotating cylinder... The rotating cylinder 8 rotates, causing the rotating plate 16 to move counterclockwise downwards. When the rotating plate 16 rotates to the top of the injection mold 23, the limiting rod 12 moves along the vertical slots at both ends of the limiting groove 9, and drives the rotating cylinder 8 to move vertically downwards. At this time, the vacuum pump 18 extracts the air inside the device to create a low-pressure environment. Then, the suction cup 21 adsorbs the injection molded part inside the injection mold 23 onto the bottom of the suction cup 21. After the injection molded part is removed, the electric slide rail 4 drives the sliding block 5 to move upwards. At this time, the rotating cylinder 8 moves clockwise upwards. When it moves to the top of the collection box 14, the vacuum pump 18 stops working to achieve the effect of discharging the material.

[0023] A support plate 17 is fixedly installed on one side of the bottom of the rotating plate 16. A vacuum distributor 20 is fixedly installed on the bottom of the support plate 17. A vacuum pump 18 is installed on the top of the support plate 17. An air supply pipe 19 is fixedly installed at the input end of the vacuum pump 18. The end of the air supply pipe 19 away from the vacuum pump 18 is fixedly installed inside the vacuum distributor 20. Multiple suction cups 21 are fixedly installed inside the vacuum distributor 20. During operation, due to the complex structure and excessive steps of the existing part picking and placing device, when picking and placing injection molded parts with a single path and short distance, the excessive steps of the part picking and placing device lead to problems affecting work efficiency. In order to make the part picking and placing more efficient, the vacuum pump 18 extracts the air inside the vacuum distributor 20. When the air inside the vacuum distributor 20 is extracted, the multiple suction cups 21 installed inside it will adsorb the injection molded parts that are tightly attached to the outside.

[0024] The injection mold 23 has four fixed sides, each with a first fixing block 24. Each of the first fixing blocks 24 has a connecting groove 25 inside. A mounting rod 28 is slidably installed inside the connecting groove 25. A fixing rod 27 is located on the outer side of the mounting rod 28 away from the first fixing block 24. A second fixing block 26 is fixedly installed on the top of the fixing rod 27. The sides of the second fixing blocks 26 are fixedly installed on the four outer ends of the vacuum distributor 20. During operation, existing pick-and-place devices are complex and involve too many steps. When picking up or placing injection molded parts along a single path and over a short distance, the excessive steps lead to reduced work efficiency. This new device, to improve efficiency, uses the mounting rod 28 connected to the connecting groove 25 inside the first fixing block 24 to achieve a limiting effect when the vacuum distributor 20 connects to the injection mold 23, preventing displacement.

[0025] Each of the fixed rods 27 has an opening inside, and a spring 29 is fixedly installed inside the opening. One end of the spring 29 is fixedly installed at the bottom of the second fixed block 26, and the other end of the spring 29 is fixedly installed at the top of the mounting rod 28. During operation, due to the complex structure and excessive steps of the existing part picking and placing device, when picking and placing injection molded parts with a single path and short distance, the excessive steps of the part picking and placing device lead to the problem of affecting work efficiency. In order to make the part picking and placing more efficient, the spring 29 located between the mounting rod 28 and the fixed rod 27 plays a buffering role when the vacuum distributor 20 comes into contact with the injection mold 23.

[0026] A control panel 13 is fixedly installed on the top of the work platform 1. The control panel 13 is electrically connected to the electric slide rail 4 and the vacuum pump 18. During operation, due to the complex structure and excessive steps of the existing part picking and placing device, when picking and placing injection molded parts with a single path and short distance, the excessive steps of the part picking and placing device lead to the problem of affecting work efficiency. In order to make the part picking and placing more efficient, this device controls the vacuum pump 18 and the electric slide rail 4 through the control panel 13, and controls the picking and placing speed more conveniently.

[0027] The top of the working platform 1 is provided with a collection box 14, which is located below multiple suction cups 21. During operation, due to the complex structure and excessive steps of the existing part picking and placing device, when picking and placing injection molded parts with a single path and short distance, the excessive steps of the part picking and placing device lead to problems affecting work efficiency. In order to make the part picking and placing more efficient, this device collects the picked injection molded parts through the collection box 14.

[0028] Working principle: During the production of injection molded parts, the part pick-and-place device picks up and places the injection molded parts. The injection molding machine body 15 injects raw material into the injection mold 23 to produce the injection molded parts. After the injection molded parts have cooled, the electric slide rail 4 drives the sliding block 5 to move up and down. When the sliding block 5 moves up and down, it drives multiple side-mounted limiting plates 6 to move up and down. When the multiple limiting plates 6 move up and down, they drive the connecting plates 7 between them to move up and down. When the connecting plates 7 move up and down, they drive the rotating cylinder 8 to move up and down. When the rotating cylinder 8 moves up and down, the limiting groove 9 inside it connects along one end of the limiting rod 12. When the rotating cylinder 8 is rotated, the rotating plate 16 moves counterclockwise downwards as the rotating cylinder 8 moves downwards. When the rotating plate 16 rotates above the injection mold 23, the limiting rod 12 moves along the vertical slots at both ends of the limiting groove 9 and moves the rotating cylinder 8 vertically downwards. At this time, the vacuum pump 18 extracts the air inside the device to create a low-pressure environment. Then, the suction cup 21 adsorbs the injection molded part inside the injection mold 23 onto the bottom of the suction cup 21. After the injection molded part is removed, the electric slide rail 4 moves the sliding block 5 upwards. At this time, the rotating cylinder 8 moves clockwise upwards. When it moves to the top of the collection box 14, the vacuum pump 18 stops working to achieve the effect of discharging the material.
