The casting molding method comprises the following steps: a mould core is placed in a cavity of a mould of the ceramic ware product in advance, the mould core is made of a material which is a solid formed in such a way that liquid is frozen at low temperature, the mould core in a solid state is placed in a molding mould in advance during casting molding, the molding mould is placed for a period of time under normal temperature after the casting molding so that the temperature of the mould core in a solid state placed in advance in the molding mould is increased to the normal temperature, and when the mould core in a solid state is changed into liquid, the liquid is discharged from a water discharging hole of the cavity chinaware. The invention is used for manufacturing cavity type ceramic wares, such as a closestool, and the like.
Description
Technical field
The present invention relates to a kind of forming method of ceramic ware product, particularly relate to a kind of casting forming method of cavity ceramic ware product.
Technical background
Though the production of ceramic ware product has had history in several thousand, but the mode of production for cavity ceramic ware product such as toilet etc. does not still have more advanced production forming method, the main at present vacuum adsorption molding technology that adopts, production efficiency is low, and a workman can only produce three to five in one day.Production technology at this poor efficiency constantly has new technology to improve, a kind of new technology of ceramic ware product moulding is disclosed in the invention of disclosed application number 93107643.9 denominations of invention of 1994.05.04 " casting forming method of ware and have the forming method of the sanitary ceramics tool of water turn of bilge " as Patent Office of the People's Republic of China, though this technology has certain improvement with respect to existing technology, but fundamentally do not enhance productivity, production technology is still complicated.Be badly in need of now solving the forming method that a kind of efficient height, technology are simple, cut down the consumption of energy.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming, the forming method of a kind of shaping efficiency height, technology is simple, cost is low cavity ceramic ware product is provided.
For this reason, the invention provides a kind of casting forming method of cavity ceramic ware product, described method is that the method that adopts moulding by casting is promptly placed core rod at the empty cavity position of the mould of ceramic ware product in advance; Described core material is the solid that liquid is formed through cryogenic freezing; Core rod with solid state when carrying out moulding by casting is placed in the mould in advance, make the temperature of the core rod that originally is placed on the inside in advance rise to normal temperature through placing a period of time at normal temperatures behind the moulding by casting, after the core rod that is solid state originally becomes liquid, from the osculum of cavity ceramic ware, discharge.
In the casting forming method of another kind of cavity ceramic ware product provided by the invention, though all possessing, a lot of materials are the performance that liquid condition is frozen into solid at low temperatures at normal temperatures, but when described core material adopts water, cost is minimum, production technology is the simplest, and can not pollute production environment; As water process cryogenic freezing Cheng Bing, its shape is identical with the shape of the cavity part of ceramic ware product, the ice cube of core rod shape is placed in the mould of ceramic ware product, behind the moulding by casting, place the ice-out Cheng Shui that makes the inside after a period of time at normal temperatures, the water that melts is discharged from mould, originally the space that core rod occupied has just become cavity again.For the water that prevents ice-out causes damage to the ware base, smear waterproof material on the surface of described core rod; Equally also can put the latex film,, water be discharged, then the latex film be extracted out from osculum as ice-out Cheng Shuihou on the surface of described core rod.
In the casting forming method of another kind of cavity ceramic ware product provided by the invention, the method for described moulding by casting is the vasopressing injection cast.Because direct moulding by casting when the profile of ceramic ware product is simple, but when ceramic ware product complex-shaped, can pour into a mould generation hole not in place, the quality of product is affected with the position that direct mode of pouring into a mould forms.Therefore, when ceramic ware product complex-shaped, can adopt the mode of vasopressing injection to carry out moulding, to guarantee the quality of product.
In the casting forming method of another kind of cavity ceramic ware product provided by the invention, when core rod is difficult to be fixed in the mould as the osculum of ceramic ware product hour, at this moment core rod is difficult to fix, though can adopt other method to strengthen with the intensity that improves ice as fine rule etc. as adding in ice; But core rod is produced to be moved.In order to improve the quality of products, on described core rod, the strong point is installed, the strong point guarantees that core rod is positioned at the position that sets in advance, and can not produce displacement in forming process.The material of the described strong point can adopt the mud with the identical material of ceramic ware product.In order to guarantee the uniformity of the strong point and whole mould material, the moisture content of the ware material that the moisture content of described strong point material and when cast are used is identical, in order to guarantee the intensity of the strong point, freezing the gaining in strength of process before the described strong point is being positioned over mould.Be placed in the compacting tool set after in forming process, the described strong point and core material can being sticked together.Bonding way can adopt the described strong point and core rod to stick together by water, is placed in the mould after fixing by freezing mode.
The casting forming method of cavity ceramic ware product provided by the invention is compared with existing method and is had the following advantages:
1. production efficiency height: a present workman of vacuum suction mode on average produces three to five every day, adopts method of the present invention can bring up to hundreds of every day;
2. energy consumption is low: adopt the vacuum adsorption molding vavuum pump to open always, adopt the present invention can reduce by 90 percent energy consumption;
3. labor cost is low: the product labour who produces same quantity only needs original 1/10th;
4. raw material require low: adopt adsorption forming tiny evenly to raw-material particle requirement, adopt the present invention to produce high-grade product with low-grade potter's clay raw material, reduce the cost of raw material.
Embodiments of the invention below by accompanying drawing is described can more be expressly understood design of the present invention, method.
