Description

TECHNICAL FIELD [0001] The present invention relates to a method of manufacturing a porcelain container for airtight sealing,

The present invention relates to a method of manufacturing a ceramic container for hermetically sealing a ceramic container by forming a screw thread on the outside of the inlet of the ceramic container and screwing a threaded cap corresponding to the inlet outer thread to seal the container, The present invention relates to a mold for manufacturing pottery containers.

Generally, ceramics refers to pots and ornaments baked in a fire at a high temperature to form earth, which can be divided into ceramics baked at a temperature of 1,300 ° C. or less and porcelain baked at 1,300 ° C. to 1,500 ° C. , Pottery and porcelain together. Such ceramics can be classified into two types: manual work, rotational force of the spindle, injection and extrusion, and double hand molding includes pinching, coiling (modeling soil), modeling (terracotta) The molding method refers to making a circular object such as a plate using the rotational force of a rotating spinning wheel, which is manually or automatically.

Recently, as disclosed in Korean Patent No. 10-0914751, a ceramic container for sealing is manufactured in which a screw thread is formed at the inlet of a ceramic container and a cap formed with a thread corresponding to the external thread of the inlet is screwed and sealed The method was introduced.

In order to produce such a ceramic container for enclosure, as shown in Figs. 1 and 2, the ceramic container is divided into two parts, the inner part of which is formed in the same shape as the outer shape of the ceramic container, Left and right gypsum molds 1 and 2 on which a threaded band seating part b is formed on the left and right gypsum molds 1 and 2, a bottom gypsum mold 3 for supporting left and right gypsum molds 1 and 2, (4) formed in a cylindrical shape and having a helical thread (4a) formed on the inner side of the thread band (4), which is located on the threaded band seating portion (b) formed on the jaws (a)

After joining the left and right gypsum molds 1 and 2 with the bottom gypsum mold 3 and the thread band 4 as shown in Fig. 2, the gypsum molds 1, The base 5 as a mass of clay clay mixed with water is inserted and the base 5 is pressed using the molding arm 6 of a molding machine rotating while rotating the gypsum molds 1,2,3, The porcelain container 7 is manufactured inside the gypsum molds 1, 2, 3 as shown in Fig. At this time, a screw thread is formed outside the inlet of the ceramic container (7). 5, the upper end of the pottery container 7 is smoothed out by cutting out the base 5 from the upper part of the gypsum mold 1 and the screw band 4 by using the cutting tool 8 .

Thereafter, when the gypsum molds 1 and 2 and the screw band 4 are separated from each other, a ceramic container 7 having threads 7a formed on the outside of the inlet as shown in Fig. 6 can be manufactured. A screw thread 7b is formed on the outside of the inlet neck 7a which is an upper portion of the ceramic pot 7 thus formed and a thread 9a corresponding to the thread 7b of the inlet neck 7a is formed inside The stopper 9 can be tightened to seal the pottery container 7 with the stopper 9 as shown in Fig.

The above-described method for manufacturing a conventional porcelain container for sealing has the following problems.

That is, a jaw (a) is protruded inward to support the screw band 4 on the inside of the upper part of the left and right gypsum molds 1 and 2. A portion of the jaw (a) is easily damaged when the molding arm is raised while pressing the base 5, which is a mass of clay, kneaded with water while rotating the gypsum molds 1, 2, 3 using the molding arm 6 that rotates there is a problem. This is because the gypsum molds 1 and 2 are repeatedly contacted with the ground 5, which is a mass of soil kneaded with water, by using the one gypsum molds 1, 2 and 3 several times to produce the ceramic container 7 As the molding arm 6 rises to the jaws a having the moisture, the pressing pressure is applied to the gypsum molds 1 and 2 much more than the other portions of the gypsum molds 1 and 2, It breaks. Therefore, the gypsum molds 1 and 2 need to be frequently replaced, which increases the manufacturing cost of the ceramic container 7.

In order to increase the durability of the jaw a, the upper and lower thickness of the jaw a can be increased. When the thickness of the jaw a is increased, the length of the neck 7a of the porcelain vessel 7 is long There is a problem to lose.

In order to support the screw bands 4, the jaws a are protruded inwardly from the inside of the upper portions of the left and right gypsum molds 1 and 2. Due to the vertical thickness of the jaws a, The length of the mouth 7a of the mouth 7a of the mouth 7 needs to be made longer.

The screw bands 4 located inside the upper portions of the left and right gypsum molds 1 and 2 also rotate together with the gypsum molds 1 and 2. As the molding arm 6 ascends and rotates, The screw band 4 to be rotated at the same rotational speed as that of the left and right gypsum molds 1 and 2 is slowed down by the pressing pressure of the mold box 6 and the screw band 4 The threaded band seating portions b of the left and right gypsum molds 1 and 2 are worn out by repetitively manufacturing the ceramic container 7, b) is easily damaged. Therefore, the gypsum molds 1 and 2 need to be frequently replaced, which increases the manufacturing cost of the ceramic container 7.

When cutting out the base 5 from the upper part of the gypsum mold 1 and the screw band 4 by using the cutting tool 8, the uppermost outer angle of the left and right gypsum molds 1, The gypsum molds 1 and 2 must be frequently replaced, thereby causing a problem that the cost of manufacturing the ceramic container 7 is increased.

Therefore, it is desired to develop a new technique for manufacturing a ceramic container for hermetic sealing capable of remarkably reducing the replacement frequency of the gypsum molds 1 and 2 and shortening the length of the neck of the porcelain container 7.

As shown in FIGS. 8 and 17, the left and right gypsum molds 10 and 20 are formed with a screw band seating portion on which the screw band 40 is seated, The first and second stepped portions 11 and 12 are ring-shaped and have a stepped shape in cross section. The threaded portion 11 is formed in a stepped manner in a direction perpendicular to the second stepped portion 12 Shaped vertical grooves 13 are formed in at least two places between the second step portion 12 and the horizontal grooves 13. The vertical grooves 14 are formed in at least two places between the second step portions 12 and the horizontal grooves 13. [ Here, the first stepped portion 11 has a smaller inner diameter than the second stepped portion 12.

The screw band 40 is formed in a substantially cylindrical shape and is coupled to the screw band seating portions of the left and right gypsum molds 10 and 20. As shown in Figs. 8, 15 and 16, And an upper stopping jaw 41 which is seated on the first stepped portion 11 of the threaded band seating portion is formed from the upper side and the upper stopping jaw 41 is formed on the lower side of the upper stopping jaw 41 An upper horizontal jaw 42 having an outer diameter smaller than the outer diameter of the upper jaw 41 and seated on the second step 12 of the screw band seating portion is formed and is spaced apart from the upper horizontal jaw 42 A lower horizontal tuck 43 is formed in the lower portion and has an outer diameter equal to the outer diameter of the upper horizontal tuck 42 and is fitted in the horizontal groove 13 of the screw band seating portion, Is formed between the lower horizontal step 43 and the vertical groove 14 of the screw band seating portion Forming at least two vertical jaws (44) and, the said vertical projection 44 and the horizontal groove 45 in a region defined by a horizontal upper jaw 42 and a lower horizontal projection 43 is formed.

A cross sectional view in which the left and right gypsum molds 10 and 20, the gypsum frame 30, and the screw band 40 constructed as described above are combined is shown in Fig.

After joining the left and right gypsum molds 10 and 20 with the bottom gypsum mold 30 and the thread band 40 as shown in Fig. 9, the gypsum molds 10, 20 and 30, The molding arm 60 of the molding machine which rotates while rotating the combined structure of the gypsum molds 10, 20, 30 and the screw band 40 is inserted into the inside of the combined structure of the gypsum molds 40, 40, The porcelain vessel 70 is manufactured inside the combined structure of the gypsum molds 10, 20, and 30 and the screw band 40 as shown in Fig. At this time, a thread is formed outside the inlet of the ceramic container (70). The cutting tool 80 is used to cut out the substrate 50 from the top of the gypsum molds 10 and 20 and the screw band 44 to smooth the upper end of the ceramic container 70 .

Then, when the gypsum molds 10, 20 and the screw band 40 are separated from each other, a ceramic container 70 having threads 70a formed on the outside of the inlet as shown in Fig. 13 can be manufactured. A thread 70b is formed on the outside of the entrance neck 70a which is an upper portion of the ceramic pot 70. The thread 90a corresponding to the thread 70b of the entrance neck 70a is formed inside The stopper 90 can be tightened to seal the porcelain container 70 with the stopper 90 as shown in Fig.

Therefore, the replacement period of the gypsum molds 10 and 20 can be increased by 2 to 3 times as compared with the conventional example, and thus the manufacturing cost of the ceramic container 70 can be remarkably lowered compared with the conventional example.

According to the present invention, since the jaws for supporting the screw bands are not required inside the upper part of the left and right gypsum molds 10 and 20 as in the conventional example, the length of the inlet neck 70a can be reduced .

According to the present invention, since the lower horizontal jaws 43 of the screw bands 40 are fitted and joined to the horizontal grooves 13 formed on the upper inner side of the left and right gypsum molds 10 and 20, The threaded band 40 does not rise even if the thread of the threaded band 40 is pushed while rotating.

According to the present invention, since the vertical protrusions 44 of the screw bands 40 are fitted and joined to the vertical grooves 14 formed on the upper inner side of the left and right gypsum molds 10 and 20, The thread band 40 rotates at the same rotational speed as that of the left and right gypsum molds 10 and 20 even when the thread of the thread band 40 is rotated while rotating, It is possible to prevent the screw band mounting portions of the left and right gypsum molds 10 and 20 from being worn by the friction with the screw band 40. [ Therefore, the replacement period of the gypsum molds 10 and 20 can be increased by 2 to 3 times as compared with the conventional example, and thus the manufacturing cost of the ceramic container 70 can be remarkably lowered compared with the conventional example.

According to the present invention, when the upper stopping jaws 41 of the screw bands 40 are formed so as to cover the upper end surfaces of the left and right gypsum molds 10 and 20, 20 and the upper end of the left and right gypsum molds 10, 20 can be prevented from being worn when the base 50 emerging from the upper portion of the screw band 40 is cut out.
