The invention discloses a rotational grinding device for the end portion of a material pulling needle of an injection mold. The rotational grinding device comprises a rack. Multiple positioning cylinders are arranged at the end portion of the rack. A positioning pipe is arranged at the lower portion of each positioning cylinder. A ceiling frame is arranged at the end portion of the rack, and the positioning cylinders are installed on the ceiling frame. A cover plate is arranged at the end portion of the rack. Multiple magnetic attraction pieces are arranged at the lower portion of the cover plate and correspond to the positioning cylinders. A lifting seat is arranged at the inner bottom of the rack, and multiple drive motors are arranged on the lifting seat. Rotating shafts are arranged at the upper portions of the drive motors, the lower ends of the rotating shafts are connected with the upper portions of the drive motors, and polishing wheels are arranged at the upper ends of the rotating shafts. A hydraulic cylinder is arranged at the inner bottom of the rack, and a piston rod is arranged at the upper portion of the hydraulic cylinder. The upper end of the piston rod is installed on one side of the bottom of the lifting seat. By means of the rotational grinding device for the end portion of the material pulling needle of the injection mold, the end portion of the material pulling needle of the injection mold can be rapidly polished through the polishing wheels, and the polished material pulling needle can conveniently conduct material pulling and demolding on a plastic product, and the effect is better.
Description
technical field [0001] The invention relates to a grinding device, in particular to a grinding device for the end of a pulling pin of an injection mold. Background technique [0002] Plastic molds are tools that are matched with plastic molding machines in the plastic processing industry to give plastic products a complete configuration and precise dimensions. Due to the variety of plastics and processing methods, and the structures of plastic molding machines and plastic products, the types and structures of plastic molds are also varied. A combined plastic mold for compression molding, extrusion molding, injection molding, blow molding and low-foaming molding. The die is a punch with a variable core composed of a punch combined base plate, a punch assembly, a punch combined clamping plate, a cavity cut-off component and a side cut combination plate. Coordinated change of mold convex, concave mold and auxiliary molding system. A series of plastic parts of different shape...
