Special tool for titanium alloy sand mold casting box turnover and application method of special tool

Abstract

The invention discloses a special tool for titanium alloy sand mold casting box turnover and an application method of the special tool. The special tool comprises a supporting plate and a fixing block, wherein the supporting plate is fixed to one side of the fixing block, and a balancing weight is arranged on the supporting plate; the fixing block is provided with a first sliding groove in the surface of the other side of the fixing supporting plate, a first motor is arranged above the fixing block, an output rotating shaft of the first motor penetrates into the first sliding groove and is connected with the top end of a one-way screw, and the bottom end of the one-way screw is rotationally connected with the bottom of the first sliding groove; a sliding block is in threaded connection with the outer surface of the one-way screw rod, a second motor is arranged on the upper surface of the sliding block, an output rotating shaft of the second motor is fixedly connected with a driving gear, a connecting rod is rotatably connected to the outer side face of the sliding block, a driven gear is fixedly connected to the periphery of the connecting rod, and the driving gear is meshed with the driven gear; and the end of the connecting rod is connected with one side of a connecting plate, and a clamping mechanism is arranged at the other side of the connecting plate. According to the technical scheme, a die can be fixed, and the stability of the die during box turnover is improved.

Description

technical field [0001] The invention belongs to the technical field of sand casting, and in particular relates to a special tooling for turning over a titanium alloy sand casting and an application method thereof. Background technique [0002] Sand casting refers to the casting method of producing castings in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting methods. Because the molding materials used in sand casting are cheap and easy to obtain, the casting molds are easy to manufacture. It can be adapted to piece production, batch production and mass production. It has been the basic process in casting production for a long time. [0003] During box-splitting sand casting, workers need to use a specific workpiece to lift the lower mold and turn it over 180 degrees, and then close the upper and lower molds. The labor intensity of the workers is relatively high, and there are certain errors in the manual turning of the box by the wor...

Problems solved by technology

[0003] During box-splitting sand casting, workers need to use a specific workpiece to lift the lower mold and turn it over 180 degrees, and then close the upper and lower molds. The labor intensity of the workers is relatively high, and there are certain errors in the manual turning of the box by the workers, which affects the casting quality of the workpiece. For this reason, we propose a special tooling and its application method for titanium alloy sand casting to solve the above problems
