Abstract
The utility model discloses a kind of gypsum mold of mud shrinkage factor detection, including upper mould cover, die shoe and cavity：Cavity is on die shoe, and upper mould cover has the air-vent for facing cavity center, and cavity shape is cuboid, and the implantation of cavity length direction two ends is not by the corrosion resistant hard plastic board of dissolving or stainless steel plate.The utility model has the advantages that：Mould cavity length direction is not influenceed by dissolved corrosion, is calculated mud bar linear shrinkage precision and is improved.
Description
Technical field
The utility model is related to a kind of detection mould, specifically a kind of gypsum mold of mud shrinkage factor detection.
Background technology
Whether ceramic dimensions reaches design requirement, control ceramic raw material, slurry line stable contraction rate and measurement
The accuracy of contraction is most important.In detection process, the accuracy of linear shrinkage measurement is improved to stablizing linear shrinkage ratio, ensureing to make pottery
Ceramic products size reaches that design requirement plays an important role.
It is conventional to shrink measuring method：Slurry is noted into rectangular enclosure plaster cast, rectangular bar is made, mud bar is through dry
It is dry, burn till after, mud bar length is burnt till in measurement, calculates mud bar shrinkage factor.
Shortcoming:During slip casting, the dissolving and mud due to gypsum are to the corrosiveness of plaster mold, often using once,
Gypsum rectangular enclosure size changes, and influences measurement accuracy.
Utility model content
The utility model is directed to above-mentioned problem, it is proposed that a kind of gypsum mold of mud shrinkage factor detection, the mould
Tool cavity length direction is not influenceed by dissolved corrosion, is calculated mud bar linear shrinkage precision and is improved.
A kind of gypsum mold of mud shrinkage factor detection of the utility model, including upper mould cover, die shoe and cavity：Cavity exists
On die shoe, upper mould cover has the air-vent for facing cavity center, and cavity shape is cuboid, the implantation of cavity length direction two ends
Not by the corrosion resistant hard plastic board of dissolving or stainless steel plate.
Preferably, cavity has two.
Preferably, upper mould cover and die shoe are cuboid.
The utility model produce beneficial effect be:Mould cavity length direction is not influenceed by dissolved corrosion, calculates mud bar
Linear shrinkage precision is improved, and the repeatable availability of mould is high, reduces die cost.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.Following instance is only to illustrate that this practicality is new
Type, is not intended to limit the utility model.
As shown in figure 1, upper mould cover 1 faces cavity center with two air-vents, cavity 2 is on die shoe 3, the shape of cavity 2
Shape is cuboid (long 100mm, wide 15mm, high 10mm), and the implantation of the length direction two ends of cavity 2 is not moulded by corrosion resistant hard is dissolved
Flitch or stainless steel plate.
Shrink measuring method：Slurry is noted into the plaster cast of cavity 2, rectangular bar is made, mud bar through drying, burn till
Afterwards, mud bar length is burnt till in measurement, calculates mud bar shrinkage factor.Shrinkage factor calculation formula is as follows：
In formula, β is shrinkage factor, L1Preceding length, i.e. cavity length, L are burnt till for mud bar2Rear length is burnt till for mud bar.
Above-described embodiment is only the preferred embodiment of the utility model, is implemented when that can not limit the utility model with this
Scope, i.e., generally according to simple equivalent made by the content described in the utility model claim and utility model specification
Change and modification, all still belong within the utility model claim scope.In addition, summary part and title are intended merely to
Auxiliary patent document search is used, not for limiting the interest field of the utility model.
