Description
Technical field
The utility model relates to a kind of device making gypsum mold, is applicable to the injection forming field of pottery.
Background technology
In ceramic production industry, gypsum mold is used maximum traditional injection forming moulds, as special cermacis etc. type ceramics shaping of sanitary ceramics, domestic ceramics, shape design complexity.Compared with the injection forming mould of other materials, the advantages such as plaster mold has its abundant raw material source, cheap, manufacture craft is simple, water absorption rate is high, good stability of the dimension.
10mm is less than for wall thickness, cross section is annular, slip casting ceramic product that diameter that length direction passes through progressively reduces, it produces the split gypsum mold that gypsum mold used is generally made at least two parts at present, during forming process of ceramics, this split gypsum mold is equipped to a set of gypsum mold and uses.
Split gypsum mold manufacture craft is comparatively complicated, for dimeric split pattern, this split pattern generally makes one piece of bed die A according to master mold, makes another half module B by bed die A and master mold, make next half module C by mould B and master mold again, mould B and mould C close one set of die.A set of Split mold, make efficiency is lower, Production Time is longer, and entirety is cuboid, uses gypsum powder more.
When using Split mold slip casting ceramic product, the instruments such as fixture need be used to be fixed together by each several part of split pattern, after slip casting completes, to need again to tear the operation such as fixture, break the mold open, make injection forming inefficiency, add that this mode causes the workloads such as shaping qualification rate is low, repaired biscuit larger.
At present, energy-conserving and environment-protective are development trends of all trades and professions.In silicon carbide ceramics industry, burner sleeve series of products, are highly generally below 800mm, are unfavorable for the kiln furnitures power conservation requirement of conventional ceramic industry.According to the requirement that the kiln furnitures of conventional ceramic industry are more energy-conservation, adopt wide kiln design to be more energy-conservation one design, the burner sleeve higher than 800mm need be adopted.But, higher than the silicon carbide ceramics burner sleeve of 800mm, when the gypsum mold made is produced, easily cause the defects such as ceramic product distortion by prior art.Wherein, deformation defect concrete condition is in radial directions as follows: need shaping silicon carbide ceramics burner sleeve product longer, after Split mold injection forming completes, easier collapse-deformation in radial directions during break the mold, to the silicon carbide ceramics burner sleeve distortion higher than more than 800mm clearly.
