Description
Technical field
The utility model relates to a kind of device manufacturing gypsum mold.
Background technology
Injection forming is a kind of ceramic molding of simple, usually using gypsum as shaping mould.The cost of manufacture of gypsum is cheap, and its raw gypsum is at China's rich reserves, cheap; Good fluidity aborning, can prepare the mould of various shape; It has unrivaled coagulability energy, water absorbing properties in addition, and be still widely used at present in the forming technologies such as slip casting, spinning, roll extrusion, plastic compression (colding pressing), there is no other materials can be completely alternative.
Traditional handicraft prepares gypsum mold, is to adopt gypsum powder and water to be modulated into gypsum slurry, through cast molding, drying and making, but is difficult to prepare the gypsum mold not only having high strength but also have excellent absorbency energy.Gypsum mold is used for ceramic target preparation field, high intensity should be had scrap to avoid mould to damage in operation and handling process, excellent water absorbing properties (water absorption rate and rate of water absorption) should be had to ensure ceramic green quality and production efficiency simultaneously, in addition, also require that gypsum mold has good decay resistance and anti-wear performance.Therefore, preparation high strength, excellent absorbency energy, there is the gypsum mold of certain decay resistance and anti-wear performance, become ceramic target and produced to urgent problem in low cost, high-quality, high efficiency future development.In order to solve the problem, have document in gypsum mold, to add reinforcing agent to promote its mechanical strength and wearability, but reinforcing agent add the decline that membership causes mould water absorbing properties, thus the instructions for use of mould to water absorption rate and absorption speed cannot be reached.
Summary of the invention
In order to solve deficiency of the prior art, it is simple that the purpose of this utility model is to provide a kind of structure, and the device of manufacture gypsum mold easy to use, the gypsum mold that this device prepares not only has high strength but also have excellent absorbency energy.
For achieving the above object, the utility model is by the following technical solutions:
Manufacture a device for gypsum mold, it comprises metal chassis and upper cover, and described upper cover covers on metal chassis, the inner die cavity forming gypsum mold, and the side of described upper cover is provided with material inlet, and opposite side is provided with material outlet; The bottom of the corresponding die cavity of described metal chassis is evenly equipped with metal column, and the coefficient of heat conduction of described metal column is greater than the coefficient of heat conduction of metal chassis.
Described metal chassis is that stainless steel is shaping, and described metal column is copper post.
The diameter of described metal column is 100-600 μm, and the distance of adjacent metal intercolumniation is 100-600 μm.
Described upper cover is shaping by acrylic material.
The gypsum mold that the utility model is produced can improve the product defects that gypsum mold causes because of bore hole size and skewness, can obtain the gypsum mold that has equally distributed one-way hole.The utility model utilizes the coefficient of heat conduction of different metal, control in freezing dry process, the nucleation site of liquid and growth direction, create an equally distributed one-way hole, be aided with hydrophobic adhesive again, form a hydrophobic film at hole wall, accelerate the discharge of moisture in dry run.Via the mode of single direction draining, hole wall tool hydrophobic property, once complete slip casting action, slurry need not be added successively, can reduce because hole size and skewness cause the inhomogeneities of powder accumulation and the difference of life embryo compactness, make the not easily broken distortion of sintered body, and more can be applied to the large-sized tabular target of making.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details:
Fig. 1 is a kind of structural representation manufacturing the device of gypsum mold of the utility model.
Detailed description of the invention
As shown in Figure 1, a kind of device manufacturing gypsum mold of the utility model, it comprises metal chassis 1 and upper cover 2, described upper cover 2 covers on metal chassis 1, the inner die cavity 3 forming gypsum mold, the side of described upper cover 2 is provided with material inlet 21, and opposite side is provided with material outlet 22; The bottom of the corresponding die cavity 3 of described metal chassis is evenly equipped with metal column 4, and the arrangement mode of metal column 4 can be 90 degree of orthogonal or 60 degree of obliques, and the coefficient of heat conduction of described metal column 4 is greater than the coefficient of heat conduction of metal chassis 1.
Described metal chassis is that stainless steel is shaping, and described metal column 4 is copper post.
The diameter of described metal column 4 is 100-600 μm, and the distance between adjacent metal post 4 is 100-600 μm.
Described upper cover 2 is shaping by acrylic material.
Adopt this practical method preparing gypsum mold, said method comprising the steps of:
1) gypsum slurry is poured into die cavity 3 from the material inlet 21 of upper cover 2, overflow to gypsum slurry from material outlet 22, after the gypsum slurry overflowed is cleaned totally, the freeze drier that whole device puts into negative 18 DEG C is carried out freezing processing 1.5-2 hour, the vavuum pump of first not open cold lyophilizer, make the liquid water in gypsum slurry carry out Hirschfeld-Klinger reaction and transfer solid ice to, solid ice nucleation is in metal column 4 position, and stabilized growth forms icicle; Wherein, described gypsum slurry comprises the mixture of following weight ratio: land plaster 40-60%, polytetrafluoroethylene (PTFE) 5%, and surplus is water; Metal chassis 1 is that stainless steel is shaping, and described metal column 4 is copper post; Use polytetrafluoroethylene (PTFE) is used as adhesive, and object, except the intensity of reinforcement gypsum mold, forms one deck PTFE film in icicle periphery simultaneously, and acceleration liquid in slip casting process in future is discharged.Solidify out in the process of solid ice at the liquid water of gypsum slurry, because only have the cold air that to touch bottom metal chassis 1 in drying machine, add that the coefficient of heat conduction of copper is stainless about 20 times, therefore liquid water can first on metal chassis 1 position of copper post start nucleation, grow up along the card direction on vertical metal chassis 1 forms icicle simultaneously.
In addition, when the mixed liquor cryocoagulation of water and PTFE, water can more early than PTFE solidify, and therefore, PTFE can separate out toward icicle surface and form one deck PTFE film, and PTFE film is between icicle and landplaster particle.
2) after at above-mentioned negative 18 DEG C of temperature, freezing processing terminates, the temperature of freeze drier being downgraded negative 40 DEG C by bearing 18 DEG C, carrying out freezing processing 1.5-2 hour, now, icicle top jag starts the dendroid icicle growing fork, until touch the upper cover 2 of top;
3) after at above-mentioned negative 40 DEG C of temperature, freezing processing terminates, the vavuum pump of open cold lyophilizer, the vacuum of freeze drier is down to 80-40mtorr, icicle is distilled under vacuum conditions become steam to be discharged, and stay the next one to have to be uniformly distributed the gypsum mold of hole.
