The present invention relates to an apparatus for forming a liquor cup, and more particularly, when molding a liquor cup including a container part and a leg part, an operation and a process of adhesively molding the leg part on the bottom of the primary molded container part are simple and of good quality. The present invention relates to a liquor cup forming apparatus.

Generally, the liquor cup is composed of a container part and a leg part. The method of molding such a liquor cup is a method of integrally molding the container part and the leg part, and first, after forming the container part first, and then attaching the leg part to the bottom of the container. Two methods of forming have been used. First, a method of integrally forming the container portion and the leg portion includes inserting and blowing a fire-bed embedded with water glass dissolved in the tip into a mold integrally engraved in the same shape as the shape of the liquor cup formed integrally with the container portion and the leg portion. The glass of liquor is formed in the shape of the mold while the glass of water buried in the tip of the injured is blown in the mold.The method of forming the liquor cup, which is divided into the container part and the leg part described above, first uses the incinerator in the same mold as the container part. After forming the container part primarily, the leg part is adhesive-molded on the bottom face of this primarily formed container part using the same metal mold | die as the shape of a leg part.

Since the present invention deals with the liquor cup which is formed by separating the container and the leg of the latter from the liquor cups formed in this way, the conventional molding apparatus according to the latter liquor cup forming method is described with reference to FIGS. 4 and 5. Will be explained.

First, the liquor cup forming apparatus of the method shown in FIG. 4 places the primary molded container portion 1 on the mold 10 having the leg molding portion 12 and then raises the plunger 23. The water glass, which is located in the working space 21, is filled in the leg forming part 12 of the mold 10, and the leg part 2 is adhesively molded on the bottom surface of the container part 1, which is used in the plunger 23. Since the tip surface is flat and the outer diameter D of the plunger 23 is larger than the diameter d of the lower end of the leg 2, the following problems are caused. That is, while the mold 10 and the plunger 23 which are in continuous contact with the high temperature water glass are expanded by the high heat, a predetermined gap c is generated between the mold 10 and the plunger 23, and the plunger Water glass leaks through the gap (c) during the rise of 23, and after completion of molding, a flash 2a is formed at the lower end of the leg 2, which requires a separate work process for removing the flash 2a. There were becoming inefficient issues. In addition, since the front end surface of the plunger 23 is flat, the bottom of the leg portion (2) formed on the bottom of the liquor cup is formed in a flat ring ring between the bottom of the liquor cup and the table surface when the liquor cup is placed on the table. The problem is that the flat part of the bottom of the leg and the flat surface of the table are closely contacted by moisture, making it very difficult to use the wine glass, and to absorb all the vibrations from the bottom of the wine glass when an abnormal table vibration or impact occurs. Since the liquor cup falls or breaks, a problem arises in that the bottom surface of the leg portion 2 is regrinded as a grinding wheel or grinding diamond to form a flat portion as a curved portion.

In the liquor cup forming method shown in FIG. 5, the bottom surface of the primary molded container portion 1 is placed on the mold 10 having the leg molding portion 12, and then dissolved in the working space 21. The water glass is injected into the leg molding part 12 by injection molding, and the leg part 2 is adhesively molded on the bottom of the container part 1. However, it has a closed end on the bottom of the leg 2, which is molded together with the injection hole portion into which the glass is injected, which takes another work process of removing and polishing the same.

Accordingly, the present invention is to solve the above-mentioned conventional problems, the object of the present invention is to provide a liquor cup forming apparatus of a simple structure, reducing the process of bonding the leg portion to the bottom of the container portion of the liquor cup It is to provide a liquor cup forming apparatus that can improve the productivity by obtaining a high quality product.
