Description
Technical Field
[0001] This utility model relates to the field of injection molding machine technology, and in particular to a tooling for sorting and removing finished products from an injection molding machine. Background Technology
[0002] In the injection molding process, after the injection molding machine completes the product injection, the finished product needs to be removed from the mold and sorted. The injection molding machine finished product removal and sorting fixture is a key piece of equipment used to achieve this operation. It can improve production efficiency and ensure product quality, and occupies an important position in the production process of the injection molding industry.
[0003] Existing injection molding machines mainly consist of an injection system, a mold clamping system, a hydraulic transmission system, and an electrical control system. Their working principle is to heat and melt plastic granules, then inject them into the mold cavity through the injection system. After holding pressure and cooling, the mold is formed. In the finished product removal stage, some simple tooling uses a single suction cup or clamp for operation.
[0004] Existing injection molding machine finished product removal and sorting fixtures have some shortcomings in actual use. During the mold ejection process, due to the lack of effective buffering and displacement compensation mechanisms, the products are prone to falling off during suction. For example, when the mold ejects the product, the impact force may cause the suction cup to temporarily lose its suction force, causing the product to fall off, affecting production efficiency and product quality. Therefore, a finished product removal and sorting fixture for injection molding machines is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a finished product removal and sorting fixture for injection molding machines, which aims to improve the problem of products easily falling off during suction due to the lack of effective buffering and displacement compensation mechanisms in the existing technology.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

Slider blocks are slidably connected to the top of each slide rail. Two movable plates are fixedly connected to the top of each slider. Multiple sliding rods are slidably connected inside each of the two movable plates. Two suction cup mounting plates are fixedly connected to the top of each sliding rod. Product suction cups are mounted on the top of each of the two suction cup mounting plates. Multiple sprue clamps are fixedly connected to the top of the support plate. Multiple fixed rods are fixedly connected to the top of the support plate. Spring 1 is fixedly connected to the outer periphery of each of the multiple fixed rods. Spring 1 is respectively fixedly connected to the bottom of each of the two movable plates. Spring 2 is sleeved on the outer periphery of each of the multiple sliding rods. A device mounting plate is fixedly connected to the bottom of the support plate. A mounting frame is fixedly connected to the bottom of the robotic arm. The device mounting plate is installed inside the mounting frame, and mounting components are provided inside the mounting frame.
[0008] As a further description of the above technical solution:
[0009] The mounting assembly includes multiple movable blocks, all of which are slidably connected inside the mounting frame. Each of the multiple movable blocks is fixedly connected to a locking block on one side facing each other, and a pull rod is fixedly connected to the other end of each of the multiple movable blocks. Each of the pull rods is fitted with a spring.
[0010] As a further description of the above technical solution:
[0011] The device mounting plate has multiple evenly distributed mounting slots inside, and the multiple locking blocks are respectively locked into the multiple mounting slots;
[0012] As a further description of the above technical solution:
[0013] Multiple product pads are fixedly connected to the top of each of the two suction cup mounting plates, and the bottom of the two product suction cups abuts against the top of the multiple product pads.
[0014] As a further description of the above technical solution:
[0015] Two limiting blocks are fixedly connected to the top of each of the two suction cup mounting plates, and the two limiting blocks abut against the left and right ends of the product suction cup respectively on opposite sides;
[0016] As a further description of the above technical solution:

[0018] As a further description of the above technical solution:
[0019] The mounting frame has multiple limiting grooves inside, and the multiple pull rods are slidably connected inside the multiple limiting grooves respectively;
[0020] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, through the cooperation of the support plate, slide rail, slider, moving plate, slide rod, suction cup mounting plate, product suction cup, sprue clamp, fixing rod, spring one, and spring two, after injection molding, the tooling moves to the material picking position. After the suction cup positions the product at the limit block, it picks up the product. When the product is ejected, the pressure spring absorbs the ejection force. After being ejected into place, the sprue clamp holds the material handle. If the product shifts during the ejection process, the left and right pull springs absorb the displacement, keeping the product in the picking state. After the sprue clamp picks up the material handle, the robot slowly moves the tooling to return the product pressure spring to its original position, separating the product from the material handle. After the product is completely removed from the mold, the robot places the product and the material handle in their respective positions. The whole process achieves stable product picking during mold ejection, preventing the product from falling off, and can accurately move the material handle and product using clamps and suction cups, meeting customer needs and improving the efficiency and stability of finished product picking and sorting of injection molding machines.
[0024] 2. In this utility model, through the cooperation between the mounting bracket, the moving block, the locking block, the pull rod, the spring, the device mounting plate, and the mounting groove, pulling the handle causes the pull rod to move, which in turn causes the moving block to slide within the mounting bracket. The moving block then causes the locking block to disengage from the mounting groove of the device mounting plate. At this point, the device mounting plate can be removed from the mounting bracket, facilitating the disassembly and installation of the tooling. This improves the maintainability of the tooling by facilitating subsequent maintenance, repair, and replacement of parts. Attached Figure Description

[0034] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Reference Figures 1-4 This utility model provides an embodiment of a finished product sorting fixture for an injection molding machine, comprising a support plate 1 and a robotic arm 18. Multiple slide rails 2 are fixedly connected to the top of the support plate 1. Slider blocks 3 are slidably connected to the top of each slide rail 2. Two movable plates 4 are fixedly connected to the top of each slider 3. Multiple sliding rods 5 are slidably connected inside each movable plate 4. Two suction cup mounting plates 6 are fixedly connected to the top of each sliding rod 5. Product suction cups 7 are mounted on the top of each suction cup mounting plate 6. Multiple sprue clamps 8 are fixedly connected to the top of the support plate 1. Multiple fixing rods 11 are fixedly connected to the top of the support plate 1. Springs 12 are fixedly connected to the outer periphery of each fixing rod 11. 2 are fixedly connected to the bottom of the two movable plates 4 respectively. Multiple sliding rods 5 are all fitted with springs 13 on their outer periphery. The bottom of the support plate 1 is fixedly connected to the device mounting plate 15. The bottom of the robot arm 18 is fixedly connected to the mounting frame 17. The device mounting plate 15 is installed inside the mounting frame 17. The mounting frame 17 is equipped with mounting components. Multiple product pads 9 are fixedly connected to the top of the two suction cup mounting plates 6. The bottom of the two product suction cups 7 abuts against the top of the multiple product pads 9. Two limit blocks 10 are fixedly connected to the top of the two suction cup mounting plates 6. The two limit blocks 10 abut against the left and right ends of the product suction cups 7 respectively on opposite sides. Two connecting plates 14 are fixedly connected to the bottom of the multiple sliding rods 5.
[0036] Specifically, support plate 1 provides a supporting foundation for the entire tooling. Slide rail 2 is fixed to the top of support plate 1, providing a sliding track for slider 3, allowing slider 3 to move smoothly on slide rail 2. A movable plate 4 is connected to the top of slider 3, driving the movable plate 4 to move with it. A sliding rod 5 inside the movable plate 4 can slide within the movable plate 4, providing guidance for the up-and-down movement of suction cup mounting plate 6. Suction cup mounting plate 6 is used to mount product suction cups 7, which are responsible for picking up products. A sprue clamp 8 is fixed to the top of support plate 1 and used to clamp the material handle. A fixing rod 11 and spring 12 cooperate... Spring 12 is connected to the bottom of the moving plate 4 and the outer periphery of the fixed rod 11, which can buffer and reset the moving plate 4. Spring 213 is sleeved on the outer periphery of the slide rod 5, which further assists the movement and reset of the suction cup mounting plate 6. The product pad 9 is located at the bottom of the product suction cup 7, which protects the product suction cup 7 and assists in positioning the product. The limit block 10 is fixed on both sides of the top of the suction cup mounting plate 6, which limits the product suction cup 7 and prevents it from shifting during operation. The connecting plate 14 connects the bottom of multiple slide rods 5, which enhances the stability and integrity of the slide rods 5.
[0037] Reference Figures 5-7 The mounting assembly includes multiple movable blocks 20, which are slidably connected inside the mounting frame 17. Each movable block 20 has a locking block 21 fixedly connected to one side facing the other, and a pull rod 22 fixedly connected to the other end of each movable block 20. Each pull rod 22 is fitted with a spring 23 on its outer periphery. The mounting plate 15 has multiple evenly distributed mounting slots 16 inside, and the locking blocks 21 are respectively locked into the multiple mounting slots 16. The mounting frame 17 has multiple limiting slots 19 inside, and the pull rods 22 are slidably connected to the multiple limiting slots 19. The end of each pull rod 22 away from the locking block 21 is fixedly connected to a limiting plate 24, and the end of the limiting plate 24 away from the pull rod 22 is fixedly connected to a handle 25.
[0038] Specifically, the movable block 20 slides inside the mounting frame 17, and its opposite-side locking block 21 can engage or disengage with the mounting groove 16 of the device mounting plate 15 to realize the installation and disassembly of the tooling structure. The pull rod 22 connects to the movable block 20, making it easy to pull the movable block 20. The spring 23 is sleeved on the outer periphery of the pull rod 22, which plays a buffering and resetting role for the movable block 20, ensuring that the locking block 21 can be stably engaged in the mounting groove 16. The mounting groove 16 is evenly distributed inside the device mounting plate 15 and cooperates with the locking block 21 to achieve precise positioning and fixation. The limiting groove 19 is opened inside the mounting frame 17 to provide a sliding track for the pull rod 22, limiting the movement direction of the pull rod 22 and preventing it from shaking randomly. The limiting plate 24 is fixed to the end of the pull rod 22 away from the locking block 21 to prevent the pull rod 22 from coming out of the mounting frame 17. The handle 25 is connected to the limiting plate 24, making it easy for the operator to hold and operate the pull rod 22 to drive the movable block 20 to move.
[0039] Working principle: During the sorting and unloading of finished products from the injection molding machine: After injection molding is completed, the robot arm 18 moves the tooling to the material handling position during the mold unloading process. At this time, the product suction cup 7, positioned by the product limit block, picks up the product, while the sprue clamp 8 holds the material handle. When the product is ejected during unloading, the spring 12 on the outer periphery of the fixing rod 11 and the spring 13 on the outer periphery of the slide rod 5 function to absorb the ejection force and ensure product stability. Once the ejector is in place, the sprue clamp 8 tightly grips the material handle. If the product shifts during the ejection process, the left and right pull springs 12 will absorb the displacement, keeping the product in a gripped state. After the sprue clamp 8 grips the material handle, the robot arm 18 slowly moves the fixture, and the product suction cup 7 returns to its original position under the action of the spring, causing the product to separate from the material handle. After the product is completely removed from the mold, the robot arm 18 places the product and the material handle in their respective positions, completing the entire process of stably gripping the product during the mold ejection process without the product falling off. The operation of accurately moving the material handle and the product using clamps and suction cups improves the efficiency and stability of the injection molding machine's finished product removal and sorting.
[0040] When maintenance, repair, or component replacement is required, the operator pulls handle 25, which moves pull rod 22, causing movable block 20 to slide inside mounting bracket 17. As movable block 20 slides, locking block 21 on the opposite side of the movable block 20 gradually disengages from the mounting groove 16 inside the mounting plate 15. At this point, the connection between the mounting plate 15 and mounting bracket 17 is released, allowing the mounting plate 15 to be removed from the mounting bracket 17 for easy disassembly of the tooling. When installation is performed after maintenance, spring 3 23 releases its tension, causing pull rod 22 to slide movable block 20 in the opposite direction, and locking block 21 re-engages into the mounting groove 16, completing the tooling installation. This facilitates subsequent maintenance, repair, and component replacement, improving the maintainability of the tooling.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
