Description

Technical Field

[0001] This utility model relates to the field of injection molding production technology, specifically to an injection molding part sprue separation and handling device. Background Technology

[0002] In the manufacturing process of plastic products, injection molding is typically used. During molding, excess molding material is generated at the gate (known in the industry as a sprue). To ensure product integrity and a good appearance, the remaining sprue needs to be removed after molding. Currently, traditionally, this is done by manually trimming the sprue after molding. However, manual trimming is inefficient, produces poor results, and is labor-intensive. Therefore, sprue cutting machines have been developed to improve upon this manual trimming method.

[0003] Currently, in existing technologies, smaller sprue materials cut off by the sprue punching machine can be discharged from the discharge port by setting a discharge port on the punching machine; larger sprue materials are separated and removed manually or by a robot. Among these methods, manual separation and removal is inefficient, while conventional robots may take the injection molded product away from the mold while removing the sprue material.

[0004] Therefore, there is an urgent need for a sprue separation and handling device for injection molded parts to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a sprue separation and handling device for injection molded parts, so as to solve the problem that conventional robotic arms in the prior art are prone to causing injection molded products to detach from the mold when separating and picking up sprue material.

A Y-axis linear module is provided on the support column. A Z-axis linear module is provided at the moving end of the Y-axis linear module. A longitudinal drive plate is connected to the moving end of the Z-axis linear module. A material-grabbing component for clamping sprue material is mounted on the outer side of the longitudinal drive plate. A positioning bracket is installed at the bottom of the longitudinal drive plate.

[0008] As an optional technical solution for a sprue separation and handling device for injection molded parts, the material handling assembly includes a slide cylinder mounted on the longitudinal drive plate along the Z-axis direction. The telescopic end of the slide cylinder is connected to a base, and finger cylinders are respectively mounted on the left and right sides of the base. The gripping end of the finger cylinder is equipped with a gripper.

[0009] As an optional technical solution for a sprue separation and handling device for injection molded parts, the bottom of the gripper is provided with a limiting rod.

[0010] As an optional technical solution for a sprue separation and handling device for injection molded parts, the Y-axis linear module includes a Y-axis base plate mounted on the support column, two relatively parallel Y-axis slide rails on the Y-axis base plate, and a Y-axis slider sliding on the Y-axis slide rails; the Z-axis linear module is connected to the Y-axis slider, and a Y-axis cylinder is mounted on the top of the Y-axis base plate, with the telescopic end of the Y-axis cylinder connected to the Z-axis linear module.

[0011] As an optional technical solution for a sprue separation and handling device for injection molded parts, Y-axis fiber optic sensors are respectively installed at both ends of the Y-axis base plate.

[0012] As an optional technical solution for a sprue separation and handling device for injection molded parts, the Z-axis linear module includes a Z-axis base plate mounted on the Y-axis slider, a Z-axis slide rail on the Z-axis base plate, a Z-axis slider slidably mounted on the Z-axis slide rail, a Z-axis drive plate mounted on the Z-axis slider, a Z-axis cylinder mounted on the top of the Z-axis base plate, the telescopic end of the Z-axis cylinder being connected to the top of the Z-axis drive plate, and a longitudinal drive plate mounted on one side of the Z-axis drive plate.

[0013] As an optional technical solution for a sprue separation and handling device for injection molded parts, a Z-axis fiber optic sensor is installed on one side of the Z-axis base plate, and a sensing block matching the Z-axis fiber optic sensor is installed on the top of the Z-axis drive plate.

[0014] As an optional technical solution for injection molding part sprue separation and handling device, a waste bin is installed on the worktable near the side of the support column.

[0015] As an optional technical solution for a sprue separation and handling device for injection molded parts, the workbench is equipped with a rotary motor, and the turntable is horizontally mounted at the output end of the rotary motor.

[0016] As an optional technical solution for a sprue separation and handling device for injection molded parts, a vertically upward positioning cylinder is installed on the worktable below the turntable. The telescopic end of the positioning cylinder is provided with a positioning rod, and the outer edge of the turntable is provided with multiple equally spaced positioning holes.

[0017] The beneficial effects of this utility model are as follows:

[0018] This utility model provides a sprue separation and handling device for injection molded parts. The device includes a worktable with a turntable rotatably mounted on it. The turntable has multiple fixtures for placing injection molds. A handling mechanism is mounted on the worktable near the turntable. The handling mechanism includes a support column vertically mounted on the worktable. A Y-axis linear module is mounted on the support column. A Z-axis linear module is mounted on the moving end of the Y-axis linear module. A longitudinal drive plate is connected to the moving end of the Z-axis linear module. A material-grabbing component for clamping sprue material is mounted on the outer side of the longitudinal drive plate. A positioning bracket is mounted on the bottom of the longitudinal drive plate.

[0019] In the above structure, after the sprue material on the injection molded product is cut off by the external sprue cutting mechanism, the turntable rotates and moves the injection mold and the sprue-cut injection molded product to below the material handling assembly. The Z-axis linear module drives the material handling assembly to move downwards, and the positioning bracket presses against the injection molded product to position it. The slide cylinder drives the finger cylinder to move downwards, and the finger cylinder drives the gripper to grasp the sprue material. The slide cylinder resets, causing the sprue material to move upwards. The Z-axis linear module resets to drive the positioning bracket and the sprue material to move upwards. Driven by the Y-axis linear module, the sprue material is moved to the top of the waste bin. The finger cylinder drives the gripper to open and throw the sprue material into the waste bin, thus completing the separation and handling of the sprue material. Because the positioning bracket can press and position the injection molded product before the gripper grasps the sprue material, it effectively prevents the sprue material from taking the injection molded product away from the injection mold during separation and handling.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0037] like Figure 1-7 As shown, this utility model provides a sprue separation and handling device for injection molded parts. The sprue separation and handling device includes a worktable 1, on which a turntable 2 is rotatably mounted. The turntable 2 is provided with a plurality of fixtures 20 for placing injection molds 21. A handling mechanism 3 is mounted on the worktable 1 near the turntable 2. The handling mechanism 3 includes a support column 30 vertically mounted on the worktable 1. A Y-axis linear module 31 is provided on the support column 30. A Z-axis linear module 32 is provided at the moving end of the Y-axis linear module 31. A longitudinal drive plate 33 is connected to the moving end of the Z-axis linear module 32. A material picking component 34 for clamping sprue material 221 is mounted on the outer side of the longitudinal drive plate 33. A positioning bracket 35 is installed at the bottom of the longitudinal drive plate 33.

[0038] The injection molding part gate separation and conveying device provided by this utility model cuts off the sprue material 221 on the injection product inside the injection mold 21 through an external gate punching mechanism. Then, the turntable 2 rotates to move the injection mold 21 and the injection product 220 with the cut sprue material 221 to below the material picking component 34. The Z-axis linear module 32 drives the material picking component 34 to move downward. The positioning bracket 35 presses against the injection product 220 to position it. The slide cylinder 340 drives the finger cylinder 342 to move downward. The finger cylinder 342 drives the gripper 343 to grasp the sprue 221. The slide cylinder 340 resets, causing the sprue 221 to move upward. The Z-axis linear module 32 resets to drive the positioning bracket 35 and the sprue 221 to move upward. Driven by the Y-axis linear module 31, the sprue 221 is moved to the top of the waste bin 4. The finger cylinder 342 drives the gripper 343 to open and drop the sprue 221 into the waste bin 4, thus completing the separation and handling of the sprue 221. Because the positioning bracket 35 can press and position the injection molded product 220 before the gripper 343 grasps the sprue 221, it effectively prevents the sprue 221 from pulling the injection molded product 220 away from the injection mold 21 during separation and handling.

[0039] Specifically, such as Figure 1 As shown, a rotary motor 23 is provided on the workbench 1, and a turntable 2 is horizontally mounted on the output end of the rotary motor 23. The rotary motor 23 drives the turntable 2 to rotate, thereby realizing the cyclic movement of the injection molded part 22 in the injection mold 21 on the circumference of the turntable 2. In this way, a sprue cutting mechanism can be installed on the workbench 1 to cut the sprue material 221 of the injection molded part 22. After the sprue material 221 is cut, the injection molded part 22 with the cut sprue material 221 is transferred to the bottom of the conveying mechanism 3 for separation and conveying of the sprue material 221. In this embodiment, the turntable 2 is preferably provided with four jigs 20, and each jig 20 can hold an injection mold 21. With the cooperation of an external robot, the sprue material 221 can be separated and conveyed for the gripping and collection of the injection molded product 220.

[0040] Furthermore, a vertically upward-mounted positioning cylinder 24 is also provided on the worktable 1 below the turntable 2, with a positioning rod connected to the telescopic end of the positioning cylinder 24; and a positioning hole 240 is respectively opened on the circumferential edge of the turntable 2 on one side of each fixture 20, with the four positioning holes 240 being equally spaced. When the turntable 2 moves the injection molded part 22 to the underside of the conveying mechanism 3, the positioning cylinder 24 drives the positioning rod to move upward and insert into the positioning hole 240 to perform real-time positioning of the turntable 2 and the injection molded part 22, preventing the turntable 2 from shifting position when the material picking component 34 picks up the sprue 221, which would result in inaccurate picking of the sprue 221. This effectively improves the efficiency and accuracy of picking up the sprue 221, and further prevents the injection molded product 220 from detaching from the injection mold 21 during the separation and handling of the sprue 221. On the other hand, in order to collect and process the sprue material 221 in a reasonable and effective manner, a waste bin 4 is also installed on the workbench 1 near the support column 30 to collect the separated sprue material 221.

[0041] In this embodiment, as Figure 2 and Figure 3 As shown, the Y-axis linear module 31 is installed at the upper end of the support column 30, the Z-axis linear module 32 is installed at the moving end of the Y-axis linear module 31, and the material handling component 34 is installed at the moving end of the Z-axis linear module 32 via a longitudinal drive plate 33.

[0042] Specifically, such as Figure 4 As shown, the material handling assembly 34 includes a slide cylinder 340 mounted on a longitudinal drive plate 33 along the Z-axis. The telescopic end of the slide cylinder 340 is connected to a base 341. Finger cylinders 342 are mounted on the left and right sides of the base 341, respectively. The gripping end of the finger cylinder 342 is equipped with a gripper 343, and the bottom of the gripper 343 is connected to a limit rod 344. In this structure, the positioning bracket 35 is located at the bottom of the finger cylinder 342. That is to say, the slide cylinder 340 can drive the gripper 343 to move up and down through the positioning bracket 35, so that the positioning bracket 35 can press and position the injection molded product 220 before the gripper 343 grabs the sprue material 221, effectively preventing the injection molded product 220 from falling out of the injection mold 21 during the separation and handling of the sprue material 221.

[0043] Furthermore, such as Figure 7As shown, the injection molded part 22 in this embodiment includes an injection molded product 220 and a sprue 221 connected to the injection molded product 220. Since the injection molded part 22 leaves a limiting hole 222 on the sprue 221 during injection molding, when the slide cylinder 340 drives the gripper 343 to move downward, the limiting rod 344 at the bottom of the gripper 343 will be inserted into the limiting hole 222. Then, the finger cylinder 342 drives the gripper 343 to accurately and firmly grasp the sprue 221. This structure improves the gripping force of the sprue 221 and prevents the sprue 221 from falling during transportation. Of course, the shape of the positioning bracket 35 can be adjusted according to the size of the injection mold 21 and the injection molded product 220 so that the positioning bracket 35 can effectively press and position the injection molded product 220.

[0044] In this embodiment, as Figure 5 As shown, the Y-axis linear module 31 includes a Y-axis base plate 310 mounted on a support column 30. The Y-axis base plate 310 has two relatively parallel Y-axis slide rails 311, and a Y-axis slider 312 slides along the Y-axis slide rails 311. The Z-axis linear module 32 is connected to the Y-axis slider 312. A Y-axis cylinder 314 is mounted on the top of the Y-axis base plate 310. The telescopic end of the Y-axis cylinder 314 is connected to the Z-axis linear module 32. Therefore, when the Y-axis cylinder 314 performs telescopic movement, it can drive the Z-axis linear module 32 and the Z-axis linear module 32. The material assembly 34 reciprocates along the Y-axis direction on the Y-axis slide rail 311 to realize the reciprocating feeding of the sprue material 221 into the waste bin 4 for collection. In order to more accurately control the travel of the material assembly 34 in the Y-axis direction, Y-axis fiber optic sensors 313 are respectively installed at both ends of the Y-axis base plate 310 to control the travel of the Z-axis linear module 32 in the Y-axis direction, thereby improving the material assembly 34's ability to grab the sprue material 221 on the injection mold 21 and to more accurately feed the sprue material 221 into the waste bin 4 for collection.

[0045] Furthermore, such as Figure 6 As shown, the Z-axis linear module 32 includes a Z-axis base plate 320 mounted on a Y-axis slider 312. A Z-axis slide rail 321 is provided on the Z-axis base plate 320, and a Z-axis slider 322 slides along the Z-axis slide rail 321. A Z-axis drive plate 323 is mounted on the Z-axis slider 322. A Z-axis cylinder 324 is mounted on the top of the Z-axis base plate 320. The telescopic end of the Z-axis cylinder 324 is connected to the top of the Z-axis drive plate 323. A longitudinal drive plate 33 is mounted on one side of the Z-axis drive plate 323. The telescopic movement of the Z-axis cylinder 324 drives the entire material handling assembly 34 to move up and down. Furthermore, to control the precise movement of the material handling assembly 34 in the Z-axis direction, a Z-axis fiber optic sensor 325 is mounted on one side of the Z-axis base plate 320, and a sensing block 326 matching the Z-axis fiber optic sensor 325 is mounted on the top of the Z-axis drive plate 323.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
