Clay crucible forming machine

Abstract

Disclosed is a clay crucible forming machine. The clay crucible forming machine comprises a rack provided with a work platform. Four perpendicularly arranged uprights or two plate frames are fixed to the parts, on the two sides of the work platform, of the rack correspondingly and symmetrically. A horizontal support plate is connected to the upper ends of the uprights or the plate frames, and an N-shaped support body is formed. The clay crucible forming machine is characterized in that an oil cylinder is installed on the horizontal support plate; an oil cylinder piston is perpendicularly downward and is connected with an upper mold moving up and down through a pressing rod; the pressing rod is sleeved with a guide sleeve transversely fixed to the N-shaped support body; a lower mold matched with the upper mold is arranged on the part, below the upper mold, of the work platform, and the periphery of the lower mold is fixedly connected with four uprights of the N-shaped support body or the two plate frames. The lower mold comprises a double-layer shell and a round or square open mold cavity which is formed by the middle of the double-layer shell. The double-layer shell is formed by combining a lower mold outer shell body and a lower mold inner cavity wall. The clay crucible forming machine has the characteristics of being simple in structure, convenient to use and install, capable of reducing manufacturing cost and the like.

Description

technical field [0001] The invention relates to a clay crucible molding machine, which belongs to the technical field of crucible molding. Background technique [0002] The crucible is a vessel or melting tank made of extremely refractory materials (such as clay, graphite, china clay, quartz or relatively difficult-melt metal iron, etc.). When there are solids to be heated over a high fire, a crucible must be used because it can withstand high temperatures better than glass vessels. Clay crucible is a container for melting glass, which is resistant to high temperature and corrosion, and cannot be replaced by other containers. In the prior art, clay crucibles are manufactured by hand, and the quality fluctuates greatly, which is difficult to control. Objectively, it is restricted by the climate, and subjectively, it is affected by human factors. Its internal quality problems such as perforation, disconnection, etc. have not been tested by modern instruments so far. The effi...

Clay crucible is a container for melting glass, which is resistant to high temperature and corrosion, and cannot be replaced by other containers

In the prior art, clay crucibles are manufactured by hand, and the quality fluctuates greatly, which is difficult to control. Objectively, it is restricted by the climate, and subjectively, it is affected by human factors. Its internal quality problems such as perforation, disconnection, etc. have not been tested by modern instruments so far. It is difficult to improve the efficiency, and the production efficiency of manual production is low, and the economic benefit is poor, especially for the production of larger clay crucibles
