Casting device for high-temperature-resistant and high-pressure-resistant pipeline connecting piece

Abstract

The invention provides a casting device for a high-temperature-resistant and high-pressure-resistant pipeline connecting piece. The casting device comprises a workbench, and a movable mold box, a fixed mold box, a mold opening and closing device, a first sand pressing device, a second sand pressing device, a sand scraping device and a pouring device are arranged on the workbench; the first sand pressing device is provided with a first sand pressing plate, the second sand pressing device is provided with a second sand pressing plate, the sand scraping device is provided with a sand scraping plate, when the movable mold box and the fixed mold box are in a mold opening state, the movable mold box is located under the first sand pressing plate, the fixed mold box is located under the second sand pressing plate, when the movable mold box and the fixed mold box are in a mold closing state, the movable mold box is attached to the position over the fixed mold box, and the mold opening and closing device drives the movable mold box to be switched between the mold opening state and the mold closing state; and the pouring device is provided with a pouring ladle and a pouring gate. The mold opening and closing device, the sand pressing device, the pouring device and the sand scraping device are used for achieving automatic mold opening and closing, automatic molding and automatic pouring control, the flatness of a parting surface is improved, and therefore the casting efficiency and the rough blank precision are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of pipeline fitting manufacturing, and in particular relates to a casting device for high-temperature and high-pressure resistant pipeline connectors. Background technique [0002] High-temperature and high-pressure pipelines are widely used in various industries. These pipelines are straight pipes, so they need to be connected with various connectors to form a complete pipeline during installation and use. Since the connector itself is also a tubular structure, it is necessary to obtain a rough billet through a casting process, and then turn the rough billet into a final product through a finishing process. The casting process is roughly as follows: [0003] Select the molding sand, then manufacture a pair of models 100 and core boxes 400 according to the size of the product, and make the core 200 through the core boxes 400 . Put the models 100 into the corresponding mold boxes respectively, and ensure th...
