Technical Field
[0001] The utility model belongs to the technical field of breaking waste materials of casting runners, in particular to a pair of casting runner pinch-off pliers. Background Art
[0002] Casting runner pinchers are a type of equipment specifically designed for post-casting cleaning. They are primarily used to separate excess parts of castings, such as risers and runners, without damaging the finished product, facilitating recycling. This improves the efficiency and quality of post-casting cleaning, effectively preventing secondary damage to the casting and reducing production costs. Their operating principle relies primarily on the power provided by a hydraulic system, with the pinchers' mechanical action achieving the pinching and separation of the runner.
[0003] The existing pinch-off pliers on the market cannot accurately hook the runner. They need to be operated by two people on the production line, one to operate the tool and the other to feed the material. This consumes a lot of workers' time and physical strength. In addition, the runner breaks and easily injures the feeding employee, posing a threat to the workers' safety. Utility Model Content
