Automatic box locking device and method for sand-lined iron mold casting pouring trolley

Abstract

The invention relates to an automatic box locking device and method for a sand-lined iron mold casting pouring trolley, and belongs to the field of machines. The automatic box locking device comprisesan upper beam, a stand column, a lifting hydraulic cylinder, a lifting movable beam and a plurality of box clamp locking and screwing devices, wherein the upper portion of the stand column is fixed to the upper beam, the lifting hydraulic cylinder is fixed to the upper beam, the plurality of box clamp locking and screwing devices are all installed on the lifting movable beam, and a piston rod ofthe lifting hydraulic cylinder is connected with the lifting movable beam; each box clamp locking and screwing device comprises a pneumatic rotation motor, a fork frame type rotary locking head and aplurality of automatic floating ball alignment devices, the automatic floating ball alignment devices are all connected with the lifting movable beam, and the fork frame type rotary locking head is installed on an output shaft of the pneumatic rotation motor. The locking device is simple and reasonable in structural design, safe, reliable, low in cost, convenient to maintain and capable of automatically locking the box clamp on the pouring trolley, meets the operation requirements of a mechanical and automatic sand-lined iron mold casting production line and meets use requirements.

Description

technical field [0001] The present invention relates to a device and a method, in particular to an automatic lock box device and method for iron mold sand-covered casting trolleys. field. Background technique [0002] As a green, high-efficiency, and energy-saving casting production technology, iron mold sand-covered casting has become one of the typical production processes for producing high-quality castings, and has been widely used in China. When iron mold sand-covered casting is used in the production of ductile iron castings, it can make full use of the graphitization expansion characteristics of ductile iron during solidification, and realize casting without risers to obtain castings with dense inner structure. In the production of iron mold sand-covered casting, the upper and lower iron molds must be locked with box clamps during the pouring of molten iron and the subsequent solidification and cooling of the castings to prevent the molten iron from being During the...

Problems solved by technology

The flat plate on the top of this patent is convenient for placing the sand box, suitable for carrying the sand box in automatic pouring production, and it is safe and efficient, but the sand box is moved to the pouring trolley, and the sand box is locked, and it is more time-consuming to move the box. Strength is completely done manually, so it still has the above-mentioned defects
