Description

Technical Field

[0001] The utility model relates to the field of lamp shade injection molding devices, and particularly to a gate trimming tooling. Background Art

[0002] "Gate" (also often referred to as sprue) specifically refers to the channel through which the plastic melt enters the mold cavity from the nozzle of the injection molding machine. It is the last limiting point that the plastic melt flows through during the injection molding process and is also the part where the plastic product separates from the gating system. The design of the gate is crucial for controlling the filling speed, reducing internal stress, improving the product quality and appearance, and enhancing production efficiency.

[0003] When injection molding lamp shades with a large volume and a thick thickness, multiple gates are usually designed on the mold to promote the uniform distribution of the molten plastic and ensure the uniform texture of the product. However, in the existing technology, the later trimming work of the gates still relies on manual operation, which not only prolongs the production cycle and increases the labor cost, but also the instability of manual operation means that it is difficult to achieve the ideal state every time when trimming. If trimmed less, the gate residue remains, affecting the product appearance and structural integrity; if trimmed more, it may cause damage to the edge of the lamp shade, further affecting the structural integrity and appearance of the product, thus affecting the finished product rate and overall quality. Summary of the Utility Model

[0032] The following are specific embodiments of the present utility model in combination with the drawings, and the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0033] As Figures 1 to 5As shown in the figure, a gate shearing tooling of the present utility model is used to shear multiple gates on an injection-molded lamp cover. The gate shearing tooling includes: a workbench 1; a conveying unit 2, which has a moving seat 3 movably arranged on the workbench 1, and the moving seat 3 is used to receive the lamp cover and convey it; a first shearing unit 4, which is arranged on the moving seat 3, and the first shearing unit 4 has a number of first hydraulic scissors 5 movably arranged, and the first hydraulic scissors 5 are used to shear the gates on the lamp cover placed on the moving seat 3; a second shearing unit 6, which is arranged on the workbench 1 and above the moving path of the lamp cover, and the second shearing unit 6 has a number of second hydraulic scissors 7 movably arranged, and the second hydraulic scissors 7 are used to shear the gates on the lamp cover conveyed by the moving seat 3.

[0034] The specific steps of the gate shearing tooling in this solution for shearing the gates of the injection-molded lamp cover are as follows: First, the lamp cover is placed on the moving seat 3 on the workbench 1. Subsequently, the first hydraulic scissors 5 on the moving seat 3 are all started synchronously to precisely shear the first batch of gates on the lamp cover. At the same time, the moving seat 3 drives the lamp cover to move to the second shearing unit 6. At this time, under the precise guidance of the second shearing unit 6, the second hydraulic scissors 7 synchronously shear the remaining multiple gates on the lamp cover on the moving seat 3. All the gates on the lamp cover are sheared. Compared with the traditional manual shearing method, the operation method of this embodiment not only significantly shortens the production cycle and greatly saves labor costs, but also ensures the accuracy of each shearing position through precise control, thereby effectively avoiding gate residue and product damage, effectively improving the finished product rate and overall product quality, reducing the generation of unqualified products, and optimizing the production process.

[0035] Specifically, the conveying unit 2 further includes: a support platform 8, support platforms 8 are arranged on both sides of the moving seat 3, and the support platforms 8 on both sides are used to support two lamp covers at the same time; slide rails 9, slide rails 9 are arranged on both sides of the workbench 1, and a number of sliders 10 are arranged on the moving seat 3, and the moving seat 3 is movably arranged on the slide rails 9 through the sliders 10; a first driving member 11, which is arranged on the workbench 1, and the output end of the first driving member 11 is connected to the moving seat 3, and the first driving member 11 is used to drive the moving seat 3 to move on the slide rails 9 through the sliders 10. The first driving member 11 is preferably a linear guide rail.

[0036] At the same time, two molded lamp covers are placed on the support platforms 8 on both sides of the moving seat 3. The first hydraulic scissors 5 arranged on the moving seat 3 are immediately started to precisely shear the first batch of gates on the lamp covers on both sides at the same time. At the same time, the first driving member 11 drives the moving seat 3 to move smoothly along the slide rails 9 on both sides of the workbench 1 through the sliders 10, and conveys the lamp cover to the position where the second shearing unit 6 is located to complete the shearing work of the remaining gates on the lamp cover. This design ensures the automation of the moving process, reduces manual intervention, and improves production efficiency and safety.

[0037] Specifically, the first shearing unit 4 further includes: a support rod 12, and a plurality of support rods 12 are evenly distributed and connected to the moving seat 3; a moving block 13, and the support rods 12 are all connected with a moving block 13. The moving blocks 13 are located on the side of the support platform 8 and are all connected with a first hydraulic scissors 5 thereon. The moving blocks 13 are used to drive the first hydraulic scissors 5 to move; a second driving member 14, and the second driving member 14 is connected to each support rod 12. The output end of the second driving member 14 is connected to the moving block 13. The second driving member 14 is used to drive the moving block 13 to move. The second driving member 14 can be a cylinder, a motor or an electromagnet.

[0038] When the lamp cover is placed on the support platform 8, the second driving member 14 is immediately started to drive the moving block 13 to accurately move to the preset shearing position. At this time, the first hydraulic scissors 5 installed on the moving block 13 are aligned with the water inlet on the lamp cover, and the shearing task is started. After the shearing is completed, the second driving member 14 is started again to drive the moving block 13 to return to the initial position to ensure that the first hydraulic scissors 5 will not interfere with the subsequent placement of the lamp cover and prepare for the next shearing cycle.

[0039] Specifically, the second shearing unit 6 includes: a third driving member 15, and a plurality of third driving members 15 are arranged on both sides of the workbench 1; a lifting plate 16, and the output ends of the third driving members 15 are all connected with a lifting plate 16. A plurality of second hydraulic scissors 7 are inclinedly arranged on the lifting plate 16. The inclined arrangement is beneficial to the best contact angle between the second hydraulic scissors 7 and the water inlet during the shearing process, improving the shearing efficiency and accuracy. The third driving member 15 drives the second hydraulic scissors 7 to lift through the lifting plate 16. The third driving member 15 is preferably a cylinder. The second shearing units 6 on both sides of the workbench 1 have symmetric and identical structures, and the number of the second hydraulic scissors 7 connected to different lifting plates 16 on the same side can be flexibly configured according to the shearing requirements, and the numbers can be the same or different. When the number of the second hydraulic scissors 7 connected to each lifting plate 16 is the same, the volumes of the lifting plates 16 are the same. If the number of the second hydraulic scissors 7 connected to each lifting plate 16 is different, the volumes of the lifting plates 16 are different to ensure stability and shearing efficiency.

[0040] When the moving seat 3 drives the lamp cover on the support platform 8 to move to the position where the second shearing unit 6 is located, the third driving member 15 located above the moving path of the lamp cover is immediately started to drive the lifting plate 16 to descend to the shearing position. At this time, the second hydraulic scissors 7 are aligned with the remaining uncut water inlets on the lamp cover, and the accurate shearing work is started.

[0041] In order to receive the waste generated by shearing the water inlets, a collection component is further arranged on the workbench 1.

[0042] Specifically, the collection components include: a funnel structure 17, with a funnel structure 17 provided below both sides of the moving path of the moving seat 3, and the funnel structure 17 is used to guide the waste material to flow downward; a collection member 18, with a collection member 18 provided below each funnel structure 17 for receiving the waste material flowing down along the funnel structure 17.

[0043] When the first hydraulic scissors 5 and the second hydraulic scissors 7 perform gate shearing on the lampshade, due to the action of its own gravity, the generated waste materials respectively flow smoothly into the corresponding collection members 18 along the funnel structures 17 on both sides, realizing the effective recycling and management of the waste materials.
