[0021] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example
[0022] All devices in this application adopt conventional models in the prior art, and the control method is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field, so this application will not explain it in detail.
[0023] Please see Figure 1-4 This utility model provides a technical solution: an injection mold for the production and processing of automotive parts, including an injection molding part sprue cutting device located on one side of the automotive parts injection mold. The injection molding part sprue cutting device includes a workbench 1, a support frame 2, a three-axis guide sliding assembly 3, a sprue laser cutting blade 4, and a dust collection hood 5. The support frame 2 is a rectangular structure installed around the workbench 1 near the top of the outer edge. Multiple debris collection through holes 21 are opened through the longer sides of the support frame 2 near both sides. The dust collection hood 5 is covered outside the support frame 2 at the top of the workbench 1. A connecting hose is connected to an external vacuum cleaner through the outer wall of the top side of the dust collection hood 5.
[0024] It should be noted that in this embodiment, the support frame 2 is installed around the workbench 1 near the top of the outer edge to provide stable support for the equipment. Multiple debris collection holes 21 are provided through the support frame to facilitate the timely discharge of debris.
[0025] Furthermore, the dust hood 5 is located outside the top support frame 2 of the workbench 1 and is connected to an external vacuum cleaner via a connecting hose. When the laser cutting blade 4 is working, the dust hood 5 can effectively protect the workbench while collecting and discharging debris, keeping the working environment clean and ensuring the quality of the finished automotive injection molded parts.
[0026] The dust hood 5 is located outside the support frame 2 on top of the workbench 1. This arrangement allows it to cover the entire laser cutting area, effectively protecting the machine and collecting debris. The dust hood 5 is made of transparent or semi-transparent material so that the operator can clearly observe the working status of the laser cutting blade. The shape and size of the dust hood 5 are also designed to match the workbench and support frame, ensuring a tight fit and effectively preventing debris from splashing. The dust hood 5 physically isolates the laser cutting blade 4 from the external environment, effectively preventing debris from splashing onto the operator or surrounding equipment. The presence of the dust hood 5 reduces the amount of dust and debris in the air, lowering environmental pollution and potential threats to the operator's health.
[0027] The dust collection hood 5 is connected to an external vacuum cleaner via a connecting hose, creating a negative pressure environment. When the laser cutting blade 4 is working, the generated debris is drawn into the dust collection hood 5 by the negative pressure and connected to the external vacuum cleaner via the hose. The filtered debris and air mixture is smoothly discharged into the external environment through the connecting hose, maintaining a clean working environment and automating debris collection. This reduces the workload and time cost of manual cleaning. Because the dust collection hood 5 can continuously collect and discharge debris, it can support the laser cutting blade to operate continuously for a long time, improving production efficiency.
[0028] Please see Figure 2 , 34. The three-axis guide sliding assembly 3 includes first electric sliding guide rails 31 with a symmetrical structure located at the top of both sides of the support frame 2. First sliders 32 are slidably connected to the top of the two first electric sliding guide rails 31. The tops of the two first sliders 32 are connected by a second electric sliding rail 33. A second sliding block 34 is slidably connected to the second electric sliding rail 33. A lifting assembly is connected to the outer wall of the second sliding block 34. The bottom of the lifting assembly is connected to the laser cutting blade 4 via an edge-removable fastener. The lifting assembly includes a fixed plate 40, a fixed rod 41, a linear guide rail 42, a rack 43, and a lifting motor 44. The fixed plate 40 is fixed to the outer wall of the second sliding block 34 in a U-shape. The fixed rod 41 is vertically inserted inside the fixed plate 40. The linear guide rail 42 is parallel to one side of the outer wall of the fixed rod 41. A linear slider on the linear guide rail 42 is connected to the inner wall of the fixed plate 40. A rack 43 is parallel to the outer wall of the fixed rod 41 on the other side. A lifting gear is meshed on the rack 43 inside the fixed plate 40. A lifting motor 44 is located on the outer wall of the fixed plate 40 on one side of the lifting gear. The output end of the lifting motor 44 extends through the fixed plate 40 and into it, connecting with the lifting gear. The edge disassembly fastener includes a fixing ring 45 fixedly sleeved at the bottom of the fixed rod 41. A fastening bolt 46 is threadedly connected to the fixing ring 45. A sprue laser cutting blade 4 passes through the fixing ring 45 and is located inside the fixing ring 45. The end of the fastening bolt 46 abuts against the outer wall of the sprue laser cutting blade 4. The first electric sliding guide rail 31, the second electric sliding rail 33, and the lifting motor 44 are connected to the controller via wires. The sprue laser cutting blade 4 is connected to the controller via wires.
[0029] It should be noted that, in this embodiment, the three-axis guide sliding assembly 3 includes two first electric sliding guide rails 31 with a symmetrical structure located at the top of both sides of the support frame, and two first sliders 32 slidably connected to these two guide rails. The two first sliders 32 are connected by a second electric slide rail 33 to form a platform that can move freely in three-dimensional space. This design enables the sprue laser cutting blade to be precisely positioned in the X, Y, and Z directions to adapt to injection molded parts of different shapes and sizes. At the same time, the second sliding block 34 on the second electric slide rail 33 is also connected to a lifting assembly for further adjusting the height of the sprue laser cutting blade.
[0030] Furthermore, the lifting assembly is a crucial component of the three-axis guide sliding assembly 3, comprising a fixed plate 40, a fixed rod 41, a linear guide rail 42, a rack 43, and a lifting motor 44. The fixed plate 40, with a U-shaped structure, is fixed to the outer wall of the second sliding block 34, providing stable support for the entire lifting assembly. The fixed rod 41 vertically penetrates the interior of the fixed plate 40 and is arranged parallel to the linear guide rail 42. The linear slider on the linear guide rail 42 is connected to the inner wall of the fixed plate 40, ensuring stability during lifting. The rack 43 is parallel to the outer wall of the fixed rod 41 on the other side and meshes with the lifting gear. The lifting motor 44 is located on the outer wall of the fixed plate on one side of the lifting gear, and its output end extends through the fixed plate 40 into its interior, connecting to the lifting gear. When the lifting motor 44 rotates... The gear transmission drives the rack 43 and the fixed rod 41 to move up and down, thereby realizing the lifting and adjustment of the sprue laser cutting blade. In addition, the bottom of the lifting assembly is connected to the sprue laser cutting blade 4 via edge disassembly fasteners. The edge disassembly fasteners include a fixing 45 fixedly sleeved at the bottom of the fixed rod 41 and a fastening bolt 46 threadedly connected to the fixing ring. The sprue laser cutting blade 4 passes through the inside of the fixing ring 40, and the end of the fastening bolt 46 abuts against the outer wall of the sprue laser cutting blade 4. This design makes the sprue laser cutting blade 4 easy to install and disassemble, and convenient for maintenance and replacement.
[0031] The working process of this utility model:
[0032] In operation, the operator places the automotive parts to be processed on the worktable and adjusts their position to suit the working range of the laser cutting blade. Simultaneously, the operator ensures the dust hood 5 is correctly installed and properly connected to the external vacuum cleaner. Next, the three-axis guide sliding assembly 3 begins operation. The first electric sliding rail 31 drives the first slider 32 to move in the X-axis direction, and the second electric sliding rail 33 drives the second slider 34 to move in the Y-axis direction, thereby achieving precise positioning of the sprue laser cutting blade on the horizontal plane. When the sprue laser cutting blade 4 moves to the designated position, the lifting assembly begins operation. Through the coordinated action of components such as the fixed plate 40, fixed rod 41, linear guide rail 42, rack 43, and lifting motor 45, the sprue laser cutting blade is adjusted... The laser cutter is positioned at a height that brings it into contact with the injection-molded part. It then emits a high-energy-density laser beam to precisely cut the sprue section of the part. During laser cutting, debris is drawn into the dust collection hood 5 by negative pressure. Since the dust collection hood 5 is connected to an external vacuum cleaner, the debris is smoothly discharged into the external environment through a connecting hose, maintaining a clean working environment. Throughout the cutting process, the controller monitors the working status of the three-axis guide sliding assembly 3, the lifting assembly, and the laser cutter 4 in real time. Once all sprue sections have been cut, the equipment automatically stops. The operator can then remove the cut automotive parts for inspection to confirm that their dimensions and quality meet requirements. If necessary, subsequent processing or assembly operations can be performed.
