Problems solved by technology

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 existing technology, clay crucibles are all hand-molded, and the quality fluctuates greatly and 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

Embodiment 1

[0027] Such as figure 1 , figure 2 , image 3 A crucible molding machine shown is used for making and molding clay crucibles, and includes a frame on which an upper mold 17 is vertically slidably connected, and the upper mold 17 is fixed to the moving end of the oil cylinder 11 on the frame Connected so that it can move up and down and press molding under the drive of oil cylinder 11, the horizontal sliding connection on the frame is provided with supporting plate 16 that can do horizontal reciprocating movement under the drive of the driving mechanism, and supporting plate 16 is set on one side and upper mold 17 The matched lower mold 19, the other half of the supporting plate 16 is the bottom plate position for placing the crucible embryo body 6, wherein the lower mold 19 is a female mold, and the upper mold 17 is a male mold. On the wall of the upper mold 17 Evenly distributed with a plurality of air holes only for gas and water to pass through, these air holes communica...

Embodiment 2

[0038] Such as Figure 10 A lower mold for a crucible molding machine shown includes a lower mold housing 191, a mold cavity 192 and a mold cavity wall 193, and a lower mold inner cavity 194 is formed between the lower mold housing 191 and the mold cavity wall 193. The mold cavity wall 193 is evenly distributed with a plurality of air holes 195 that only allow gas and water to pass through. In this way, during the pressing process, the gas and water extruded from the mud can be discharged into the inner cavity 194 of the lower mold through the air holes 195, thereby further improving the density and uniformity of the crucible body, and further avoiding perforation, cracking, etc. Quality issues while saving drying time. In order to prevent mud particles from entering the inner cavity of the upper mold or the surface of the crucible body is rough during pressing, the diameter of the pores on the cavity wall 193 of the lower mold is preferably 2-5 mm. The lower mold shell 191 ...

Embodiment 3

[0041] Such as Figure 11 A lower mold for a crucible molding machine shown includes a lower mold housing 191, a mold cavity 192 and a mold cavity wall 193, and a lower mold inner cavity 194 is formed between the lower mold housing 191 and the mold cavity wall 193. A plurality of air holes 195 are evenly distributed on the cavity wall 193, and a filter cloth 197 covering the cavity wall 193 is provided in the cavity 192 of the lower mold. connected. Like this, in the pressing process, the gas and water from the mud material will be discharged in the lower mold cavity 194 through the filter cloth 197 and the air hole 195 due to extrusion and vacuum effect, so that the upper mold and the lower mold are separated from each other. The inside and outside of the crucible body removes the gas and moisture, thereby further improving the density and uniformity of the crucible body, further improving the quality of the product, and saving drying time; and during the demoulding process ...

Abstract

The invention discloses a crucible forming machine which comprises a frame, wherein an upper die is vertically and slidably connected and arranged on the frame, the upper die is fixedly connected with the movable end of an oil cylinder arranged on the frame so as to be capable of realizing up and down movement and die-pressing forming under the drive of the oil cylinder, a supporting plate which can do horizontal reciprocating motion under the drive of a driving mechanism is horizontally and slidably connected and arranged on the frame, a lower die matched with the upper die is arranged on one half edge of the supporting plate, and a baseplate position for shelving a crucible blank is arranged on the other half edge of the supporting plate, the lower die is a female die, the upper die is a male die, a plurality of gas holes through which gas and water can pass are uniformly distributed on the wall of the upper die, the gas holes are communicated with a vacuum pump through the inner cavity of the upper die, and the lower die and the upper die are welded by use of metal plates. According to the technical scheme, not only can the product quality be ensured, but also the production efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of crucible manufacturing, in particular to a crucible forming machine. 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.). The crucible is a bowl-shaped container with a deep ceramic bottom. 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 and 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, disconnectio...
