Description

Technical Field

[0001] This utility model relates to the field of injection mold processing technology, specifically to a gate cutting and grinding mechanism for injection molds. Background Technology

[0002] The molding cycle of plastic products and the subsequent processing of gates and flash directly affect the production cost and quality of the products. For example, if the gate needs to be cut off, the usual method is for workers to use a cutter to cut a circle around the gate little by little, and then use a sledgehammer to break it off. This is time-consuming, labor-intensive, inefficient, and can easily lead to safety hazards.

[0003] For example, application number CN202020546772.6 discloses a gate cutting and grinding mechanism for injection molds, specifically relating to the field of injection mold processing. It includes a fixed block with a mounting groove at its bottom. A threaded rod is engaged in the middle of the mounting groove, and a cutting tool is engaged in the middle of the threaded rod. Protective clamping devices are fixedly connected to both sides of the cutting tool, and a locking nut is fixedly installed on one side of each protective clamping device. In practical use, this invention uses protective clamping devices to dampen the shaking of the cutting tool during movement, ensuring that the cutting tool does not lock up during operation, thus effectively improving the overall cutting effect of the device. A telescopic rod is used to move the grinding and chip removal device closer to the gate, thereby cleaning the debris on the gate surface and preventing debris from accumulating around the gate and affecting subsequent cuts.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can address the issue that the constant movement of the cutting tool can cause impact and wear on the connection between the cutting tool and the locking nut, potentially leading to tool locking and affecting the cutting of the gate, and the generation of debris around the gate after cutting, the original prior art lacks any deburring or polishing device. This debris can cause errors in subsequent cuts. Furthermore, while the device cleans the debris around the gate using a deburring brush, the lack of a dedicated cleaning structure leads to debris accumulation on the mounting base, requiring manual collection and impacting subsequent processing efficiency.

[0024] As a technical optimization of this utility model, by setting a transmission component 9, the motor 91 can drive the gear 92 to rotate after starting, and the gear 92 can drive the toothed ring 93 meshing with the gear 92 to rotate, so that the toothed ring 93 can drive the rotating ring 8 to rotate, and the rotating ring 8 can drive the cleaning rod 10 to rotate.

[0025] refer to Figure 3 The mounting component 12 includes a mounting pin 121, and a mounting groove 122 is provided on the front side of the top of the rotating ring 8. The mounting pin 121 is inserted into the mounting groove 122.

[0026] As a technical optimization of this utility model, by setting the installation component 12, the cleaning rod 10 can be installed by inserting the installation pin 121 into the installation slot 122, thereby increasing the convenience of using the cleaning rod 10 and increasing the flexibility of using the cleaning rod 10.

[0027] refer to Figure 3A limiting groove 13 is provided on the top of the toothed ring 93, and a limiting ring 14 is movably connected inside the limiting groove 13. The top of the limiting ring 14 is fixedly connected to the bottom of the guide ring 7.

[0028] As a technical optimization of this utility model, by setting a limiting ring 14, the use of the limiting ring 14 can limit the toothed ring 93, thereby limiting the rotating ring 8 through the toothed ring 93, ensuring the stability of the toothed ring 93 and the rotating ring 8 during rotation.

[0029] refer to Figure 3 The collection tank 11 is movably connected to a collection box 15, and a grip frame 16 is fixedly connected to the front side of the collection box 15.

After the motor 91 starts, it drives the gear 92 to rotate. The rotation of the gear 92 drives the toothed ring 93 at the top of the rotating ring 8 to rotate. The toothed ring 93 drives the rotating ring 8 to rotate. The rotating ring 8 drives the cleaning rod 10 to rotate through the mounting pin 121 inside the mounting groove 122. After the cleaning rod 10 rotates, it pushes the waste on the mounting base 1 to rotate. When the waste on the mounting base 1 is pushed onto the collection groove 11 by the cleaning rod 10, it will fall into the collection box 15 in the collection groove 11, thereby cleaning and collecting the waste, thus achieving the effect of assisting in the collection of waste.

[0036] In summary, this injection mold gate cutting and grinding mechanism, by setting a cleaning rod 10, can push the waste debris on the mounting base 1 into the collection tank 11 to clean and collect the waste debris. This solves the problem that in the process of using a shaving brush to sweep the waste debris around the gate without setting a cleaning structure, the waste debris will accumulate on the mounting base and need to be manually cleaned and collected, which will affect the efficiency of subsequent processing.
