Abstract
The present invention discloses a molding method for a sculpture mold comprising the following steps: a heating step of selecting vinyl acetate-ethylene copolymer as a mold raw material, and heating the mold raw material to 60 DEG C-80 DEG C, adding talcum powder in the mold raw material which is in a thick slurry state, and continuously heating the mixture of the mold raw material and the talcum powder to a fully melting state; a moulding step of coating the mixture of the mold raw material and the talcum powder in the fully melting state on the surface of a sculpture model which is coated with an isolating agent and forming a mold layer; a separation mold step of firstly cooling the sculpture model coated with the mold layer to a room temperature, separating the mold layer from the sculpture model and obtaining the mold. The molding method of the invention has advantages of simple operation, rapid forming, low cost without toxin or pungent odor during the molding process, and enables the molding material to reclaim and reuse, which is green environmental protection.
Description
Technical field
The present invention relates to a kind of Tool and Die Technology, relate in particular to a kind of mold for sculpture forming method.
Background technology
When making artistic sculpture, gypsum need be added water and be mixed with calcium plaster, drying and moulding behind the injection mould.In traditional sculpture technology, it is that raw material is made that described mould all adopts silicon rubber to add solidification liquid, and these two kinds of raw materials are disposable material, can't recycle, and its dry period is all about half a day to one day, the a whole set of technological forming time, total cognition surpassed more than one and half, and the activity duration is long, and will discharge a large amount of waste water and waste residue in the Mold Making process, also has one pungent smell, cause environmental pollution serious, these two kinds of cost of material height, and can only disposablely use.
Summary of the invention
Technical problem to be solved by this invention is: a kind of forming method of mold for sculpture is provided, and this method moulding is fast, and cost is low, and manufacturing process is nontoxic to have no irritating odor environmental protection.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of forming method of mold for sculpture comprises the steps:
Heating steps, selecting the ethylene vinyl acetate co-polymer for use is the mould raw material, and after the mould raw material is heated to 60 ℃-80 ℃, in being the mould raw material of underflow state, add talcum powder, and continue to be heated to the mould raw material and talcous mixture is complete molten state;
The mold step is covered in the sculpture mold surface that the surface scribbles interleaving agent with the mould raw material of complete molten state and talcous mixture and forms the mould layer;
Divide the mould step, earlier the described sculpture model that is coated with the mould layer is cooled to room temperature after, the mould layer separated on the sculpture model promptly obtains mould.
The invention has the beneficial effects as follows:
Embodiments of the invention are by with the heating of the ethylene vinyl acetate co-polymer material of low temperature and stir and it is melted fully make mold for sculpture, operate very easy, but rapid shaping, cost is low, nontoxic having no irritating odor can be reclaimed use, environmental protection repeatedly.
Below the present invention is described in further detail.
The specific embodiment
The ethylene vinyl acetate co-polymer material that the present invention relates to a kind of low temperature is applied to mold for sculpture and the process of rapid shaping comprises the steps:
Employing was smeared the vinyl acetate copolymerized laminate material of low temperature ethylene of interleaving agent as the mould raw material, be heated to 60 ℃-80 ℃ and make its fusing, because the mould raw material after the fusing can not mix with water, during specific implementation, described mould raw material can be put into hot water and stir and make its fusing be the underflow shape, or the water proof heating;
In being the mould raw material of underflow shape, add talcum powder, can also optionally add pigment, continue to be heated to the mould raw material and talcous mixture melts fully;
The mould raw material and the talcous mixture of complete molten state are covered in the sculpture mold surface formation mould layer that the surface scribbles interleaving agent, the surface can be immersed in the mould raw material after the fusing fully with the sculpture model of interleaving agent, or the mould raw material after will melting fully directly is applied in the sculpture model surface that the surface has interleaving agent with talcous mixture;
Immerse the described sculpture model that is coated with the mould layer in the cold water or after at room temperature naturally cooling to room temperature, the mould layer is separated on the sculpture model promptly obtain mould.
The ethylene vinyl acetate co-polymer is plastics very common on a kind of market, and it is mainly used in all kinds of hard material products of pasting in production and the life, is commonly called as thermosol.Adopt the ethylene vinyl acetate co-polymer material of low temperature to add behind an amount of age resister, the modifier in the present embodiment, mainly contain following advantage as raw material:
Light weight, heat insulation, the insulation, moistureproof, fire-retardant, acid and alkali-resistance, anticorrosive;
Stability, dielectricity is good, durable, anti-aging, easily welding and bonding;
Bending strength and impact flexibility are strong, and ductility is higher when breaking;
By mediate, very easily rapid processing moulding of technology such as mixing, pulling-on piece, pelletizing, extruding or die casting, can cast or spread upon on the sculpture model, satisfy the needs of various planes or stereoscopic sculpture model;
Smooth surface, lovely luster, be rich in ornamentally, the decorative applications face is wider;
Nontoxic having no irritating odor, environmental protection is used in recyclable fusing repeatedly.
The above is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also are considered as protection scope of the present invention.
