Dewaxing mold shell overturning and conveying device

Abstract

The invention relates to a dewaxing mold shell overturning and conveying device. The problems that in a fired mold precision casting process, mold shells are conveyed manually, the labor intensity is high, the work efficiency is low, and automatic and continuous production cannot be implemented are solved. The dewaxing mold shell overturning and conveying device is characterized in that a rotating central shaft (3) is arranged on a support (1); a left jaw (4) and a right jaw (5) which can slide relatively are arranged on the rotating central shaft (3); after the left jaw (4) and the right jaw (5) are combined, a mold shell (6) can be clamped; the rotating central shaft (3) is driven to rotate in a reciprocating manner at an angle of 180 degrees by a driving device (7); and the left jaw (4) and the right jaw (5) are driven by the rotating central shaft (3) to overturn at an angle of 180 degrees. The mold shell is clamped by the left jaw and the right jaw which overturn in a reciprocating manner at an angle of 180 degrees, mold shell dewaxing and mold shell roasting are sequentially carried out automatically, the labor intensity of workers is reduced, the work efficiency is improved, the mold shells are uniformly placed on a roasting conveying belt, and a roasting effect is high.

Description

technical field [0001] The invention relates to a mold shell conveying device used in investment precision casting, in particular to a dewaxed mold shell turning conveying device. Background technique [0002] Investment casting can produce castings that are precise and complex, close to the final shape of the product, and can be used directly after a small amount of processing or no processing. It is widely used in aviation, automobiles, machine tools, ships, internal combustion engines, gas turbines, telecommunication instruments, In the manufacturing industries of weapons, medical equipment and knives. The process of investment precision casting generally includes the following processes: processing wax patterns, manufacturing mold shells (also called mold shells) through wax patterns, and then dewaxing and roasting the mold shells. During dewaxing, the open end of the mold shell is transported down to the wax melting furnace through the conveyor belt, and the wax mold m...

Problems solved by technology

[0003] In order to solve the problems of high labor intensity, low work efficiency and incapable of automatic continuous production of mold shells in the process of investment precision casting, the invention provides a dewaxed mold shell overturning conveying device, which adopts 180°reciprocating reciprocating left jaw and right jaw clamp the mold shell, turn the mold shell from the dewaxing conveyor belt to the roasting conveyor belt according to a certain beat, and realize the automation of mold shell dewaxing and mold shell roasting The connection reduces the labor intensity of workers and improves work efficiency. The mold shells are evenly placed on the roasting conveyor belt, and the roasting effect is good.
