Iron ingot transport box

Abstract

The invention relates to an iron ingot transport box. Two movable doors capable of opening and closing a lower opening of a box body are hinged to the bottom of the box body; lifting self-locking devices connected with the movable doors are respectively arranged at the two ends of the box body; each lifting self-locking device comprises a damping oil cylinder, a pulley support, pulleys and hinges;and the hinges can drive the movable doors to close the lower opening of the box body when the pulleys move upwards along with piston rods. According to the iron ingot transport box, the lifting self-locking devices are arranged, and when the iron ingot transport box is transported through lifting hooks, the hinges can drive the movable doors to close the lower opening of the box body, and the self-locking of the movable doors of the lower opening of the box body is realized by utilizing the weight of the box body and iron ingots in the box body in the lifting process, so that the lower opening of the box body is reliably closed; and when upward lifting acting force of the lifting hooks disappears, the gravity of the iron ingots in the box body acts on the movable doors, so that the movable doors drive the pulleys, the pulley supports and the piston rods to move downwards through the hinges, and the movable doors automatically swing downwards to open to realize automatic discharging.

Description

technical field [0001] The invention relates to casting production equipment, in particular to an iron ingot transfer box. Background technique [0002] Lost foam casting (also known as solid casting) is to bond and combine paraffin or foam models similar in size and shape to castings to form a model cluster. After brushing refractory paint and drying, it is buried in dry quartz sand for vibration molding. Down pouring, the model is vaporized, the liquid metal occupies the position of the model, solidified and cooled to form a new casting method. Lost Foam Casting is a new technology with nearly no allowance and precise molding. This technology does not need to take molds, has no parting surface, and no sand core, so the casting has no flash, burr, and draft angle, and reduces the risk of damage caused by the core. The dimensional error caused by the combination and the high surface quality of the casting can greatly reduce the cost of machining. Compared with the tradition...
