The present invention relates to a device for lifting an artificial marble bath molded in a bath mold, and more particularly, to an artificial marble bath molded from a bath mold so that the artificial marble bath having various patterns transferred onto the surface thereof can be molded without being damaged. Of the lifting device.

On the other hand, it is obvious that the artificial marble applied in the present invention is widely used in various fields, it is generally used mainly for kitchen equipment or sanitary equipment. In this case, the kitchen equipment items may be an example of a sink top plate, and the sanitary equipment items may include a bath and a sink and a wall of a bathroom or a bathroom. Such a bath, wash basin, bathroom or bathroom wall, sink top plate, etc. is usually made of artificial marble.

Therefore, the following description will be made in detail with reference to an example of an artificial marble bath among the walls, sinks, tops of sinks, sinks, toilets or bathrooms made of artificial marble according to the present invention. However, the 'method of transferring various patterns on the surface of the artificial marble' to be implemented in the present invention is not limited to the artificial marble bathtub, but all sanitary equipments and sinks, such as a sink made of artificial marble and a bathroom or bathroom wall, etc. It is known in advance that it can be applied equally to all kitchen appliances. Therefore, the scope of the claims set forth in the claims of the present invention should not be limited to the bathtub and should be applied to all kitchen equipment and sanitary equipment.

As is well known, bathing has been practiced in recent years for the purpose of keeping the body clean, but also for the purpose of healing and stabilizing the mind and body. Hot water at 37-44 ℃ is known to loosen muscles. By expanding the blood vessels in the skin, blood circulation is promoted and the toxins in the skin are easily released. Warm water at 32-36 ° C relieves tension, and cold water at 24 ° C or lower can help reduce body swelling.

Due to the advantages and effects of such baths, baths have recently been provided in each home so that the baths, which were previously mainly performed in public baths, can be performed in each home.

On the other hand, since the tub is a functional aspect such as far-infrared radiation or bacterial growth prevention is very important to have a beneficial effect on the body of the bather, conventionally has been devised a method for the tub to maximize this functionality.

Recently, however, bathrooms have also been recognized as an important part of the interior of the house, and the need for high-quality bathtubs and aesthetic beauty has been steadily rising.

A typical bathtub of the prior art luxurious impression is a marble bathtub. The marble bath is made of marble by processing a bath, such a marble bath is expensive to manufacture, heavy weight is not easy to construct. In addition, in the case of a marble bath, because the texture is limited, it is difficult to satisfy all of the user's various tastes or personalities, and there is a problem in that the purchase floor is limited to a specific layer or a certain class of people.

Accordingly, in recent years, artificial marble is used to manufacture bathtubs, sinks, and counter tops. The artificial marble can not only realize various textures, but also can be easily supplied to general consumers due to its easy construction and low production cost. There is a situation that is widely installed.

On the other hand, such artificial marble is specifically disclosed in Korean Patent Laid-Open Publication No. 10-2008-0001068 and No. 10-2010-0099836. The prior application is characterized by artificial marble consisting of quartz, feldspar, photoanalysis, pure alkali, zinc oxide, sodium nitrate and artificial marble consisting of silicon dioxide, aluminum oxide, calcium oxide, KNaO.

It is evident that the artificial marble of the present invention, which is configured as described above, is an environmentally friendly artificial marble which has a bright surface and is very smooth and does not crack or weather even after long-term use and is not polluted by pollution.

However, since the artificial marble is molded at a high temperature, there is a disadvantage in that it is not possible to perform a transfer printing capable of printing various patterns and high quality. Therefore, in the related art, aesthetics are realized through bonding an adhesive sheet having a printing layer to a bathtub or a sink or a sink top plate made of artificial marble or screen printing, which is a common printing method.

However, when a printed layer having various patterns is formed by an adhesive sheet or a screen printing method as in the related art, a transparent and clear printed layer cannot be formed, and in particular, when a long time passes, the printed layer is peeled off and dirty. Accordingly, in the art, there is no situation in which the marble or the sink or sink is installed on the top plate of the marble without forming various printed layers.

On the other hand, the artificial marble bath with the printed layer is taken out to the outside through a drying process in the heating furnace, wherein the artificial marble bath is formed of quartz, while the bath mold for forming the artificial marble bath is made of cast iron when drying In the equation, the temperature difference occurs, and thus, the artificial marble bath formed during the separation process is broken.
