Full-automatic box turnover device

Abstract

The invention discloses a full-automatic box turnover device, and relates to the field of evanescent mode casting. The full-automatic box turnover device comprises a base and two floor stands installed on the base. An installation groove is formed in the base. A two-way air cylinder is installed inside the installation groove. Two sliding blocks are installed on the base. Two piston rods of the two-way air cylinders are connected with the two sliding blocks respectively. An installation plate is installed on the base. A pair of crossed connecting rods are hinged to the lower surface of the installation plate. The lower ends of the connecting rods are hinged to the sliding blocks. The opposite faces of the two floor stands are each provided with a pushing device, and a fixing disc is fixedly installed at the other end of each pushing device. A rotating disc is rotationally arranged on each fixing disc. Clamping jaws are installed on the rotating discs. A driving motor is installed on the base. A driving wheel is installed on a rotating shaft of the driving motor and is in transmission connection with the rotating discs through racks. The full-automatic box turnover device can automatically turn over boxes, the boxes can be turned over easily, operation is convenient, and the box turnover efficiency is high.

Description

technical field [0001] The invention relates to the field of lost foam casting, in particular to a fully automatic box turning device. 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. Among them, sand burying, vibration molding, pouring, and liquid molding are all completed in the casting box. After molding, the casting box needs to be turned over to pour sand to take out the model and castings. Now the lost foam casting is an assembly line operation, that is, the bottom of the casting box is equipped with wheels, and the wheels travel on the guide rail. At the same time, there are multiple casting b...

Problems solved by technology

Now the lost foam casting is an assembly line operation, that is, the bottom of the casting box is equipped with wheels, and the wheels travel on the guide rail. At the same time, there are multiple casting boxes on the guide rail to complete the pouring and molding of the castings in sequence. To turn over the casting box, you need to turn it over. The casting box is hoisted by a crane to the box turning machine for off-line turning and sand dumping, which is complex in operation and low in production efficiency
