Tie-bar-less two-plate blow molding machine electric mold opening and closing device with quick mold adjustment function and method for realizing mold opening and closing

Abstract

The invention relates to a pulling-rod-free two-plate type blow molding machine electric mould opening and closing device with a quick mould adjusting function. The device comprises a cavity half module installation plate, a mould core half module installation plate, mould adjusting assemblies, connection rod mechanisms, a guide element, a mould closing rack, a mould moving rack and a mould opening and closing electric driving unit. The cavity half module installation plate and the mould core half module installation plate directly face and are installed on the guide element fixed to the top end of the mould closing rack. The back of the cavity half module and the back of the mould core half module installation plate are each provided with a mould adjusting assembly. The mould opening and closing electric driving unit is installed at the lower end of the mould closing rack. The connection rod mechanisms are hinged to the mould adjusting assemblies, the mould closing rack and the mould opening and closing electric driving unit through hinge pins respectively. The cavity half module, the mould core half module installation plate, the mould adjusting assemblies, the connection rod mechanisms, the guide element, the mould closing rack and the mould opening and closing electric driving unit are integrally installed on the mould moving rack. The invention further relates to a blow molding machine electric mould opening and closing method. The device is compact in structure, the mould opening and closing stroke can be quickly adjusted, industrial application is convenient, and the device belongs to the technical field of high-molecular material blow molding machines.

Description

technical field [0001] The invention relates to the mold opening and closing technology of polymer material blow molding machinery, in particular to an electric mold opening and closing device for two-platen blow molding machinery without tie rods and a mold opening and closing method realized therefor. Background technique [0002] Plastic blow molding is the third largest plastic molding method next to extrusion molding and injection molding. The molded products are widely used in industrial fields such as automobiles, packaging, and construction. Generally, plastic blow molding machinery is mainly composed of extruder, parison head, mold opening and closing device, control system, frame and other parts. Among them, the mold opening and closing device is an important part of the plastic blow molding machine, which is directly related to product performance, production efficiency and the manufacturing cost of the whole machine. [0003] For a long time, the mold opening an...
