Mold-melting shell maker

Abstract

The invention relates to a mold-melting shell maker, and belongs to the field of shell maker equipment. The mold-melting shell maker comprises a base (1), a rotary workbench (6) arranged on the base (1) rotationally, a linear lifting mechanism arranged above the rotary workbench (6) vertically and a horizontal connecting arm. The inner end of the horizontal connecting arm is fitted on the linear lifting mechanism, and the horizontal connecting arm can slide along the linear lifting mechanism vertically; the outer end of the connecting arm is fixed with a vertical rotary lifting mechanism, the lower end of the rotary lifting mechanism is fixedly connected to a breaker (26) through a universal joint (28), the upper portion of the breaker (26) is provided with a breaker bearing seat (27) provided with a bearing inside, the corresponding distance between the breaker bearing seat (27) and the rotary lifting mechanism is fixed through a pull rod (43), and the lower end of the pull rod (43) is hinged with the breaker bearing seat (27). The mold-melting shell maker has the advantages that slurry sticking and sand sticking can be performed automatically, operating efficiency is improved, the thickness of a wax mold shell is uniform, and quality is stable.

Description

technical field [0001] An investment shell making machine belongs to the field of shell making equipment, and in particular relates to a shell making machine with multi-station automatic slurry and sand sticking. Background technique [0002] In the process of shell making by investment molding, it needs to go through processes such as dipping, sanding, hardening, and drying, and this process must be repeated many times to complete the production of the shell, and the labor intensity of the workers is very high. Chinese patent 20125340975.5 discloses a multi-station automatic swing shell making machine for investment casting, which realizes the conversion between each station through the rotation of each operation support frame, which can greatly improve the production efficiency of investment casting, but this patent and Other shell making machines have not solved the problem of automatic sand sticking of the formwork. At present, the sand is still sprinkled manually. The m...

AI Technical Summary

Problems solved by technology

When the rotary lifting mechanism is lowered, the loading and unloading device is constrained by the pull rod to rotate from the vertical position to the horizontal position, so that the workpiece on the loading and unloading device can touch the sand surface horizontally. The surface is rotated to achieve uniform sand sticking, which overcomes the problems of low efficiency of manual sanding, uneven sanding, uneven thickness of the wax mold shell, and unstable product quality.
