Description

A method for manufacturing a porcelain inlet that can be combined with a ready-made product and a mold for manufacturing the same}

The present invention relates to a method for manufacturing a pottery inlet that can be coupled to a ready-made product and a mold for manufacturing the same.

The contents described in this part simply provide background information on the present invention and do not constitute prior art.

In order to produce a work or product by combining pottery with a ready-made product having a predetermined size, great efforts must be made to produce a connecting part that is connected to the ready-made product. Pottery is completed by firing clay objects, and the volume and size of the finished pottery are reduced due to the inherent shrinkage rate of the soil compared to the size of the first object. Therefore, in order to manufacture ceramics that are well combined with ready-made parts, it is essential to manufacture the connecting parts through a separate process.

Although there is a technology that uses a separate manufacturing frame to go through a separate process to manufacture the connection part with a ready-made product, it is not relatively easy to make it by pouring slip, but it is necessary to directly put clay and mold it by hand. There was a tendency that the time and effort invested was excessive compared to the performance.

Accordingly, the present inventors have completed the present invention by repeating intensive research in order to develop a technology capable of manufacturing a simple and reliable connection part (inlet part).

Figure 3 is a view showing that the pottery inlet according to an embodiment of the present invention is a main body and a separate production.

As shown in FIGS. 1 to 3 , the ceramic inlet 10 according to an embodiment of the present invention may be configured to be coupled with a ready-made part 1 . As an example, what is shown in the drawing relates to a perfume bottle made of ceramic material, and a spray structure 1 capable of spraying perfume may be coupled to the upper portion of the ceramic perfume bottle. However, pottery made of clay undergoes drying and firing processes and shrinks in size and volume due to moisture evaporation, etc. Since it is formed smaller than the spray structure 1, there is a problem in that it is not coupled. In order to solve this problem, as shown in FIG. 3, the inlet part 10 is manufactured in a separate process using a separate frame so that the final object is properly coupled to the ready-made part 1, and then the separately manufactured inlet part After combining (10) with the main body (20), it is dried and fired, and finally the ready-made part (1) can be combined with the inlet (10). Below, a manufacturing method for manufacturing the inlet part 10, a manufacturing mold for manufacturing the inlet part, and a manufacturing method of the manufacturing mold will be described in detail.

As shown in FIG. 4, the inlet manufacturing frame 100 according to an embodiment of the present invention may include an upper mold part 200, an intermediate mold part 300, and a base mold part 400. . More detailed information will be given later.

Referring to Figures 5 and 6, it is possible to understand the process of manufacturing the inlet portion 10 using the inlet portion production frame 100 according to an embodiment of the present invention. The manufacturing method for manufacturing the inlet part 10 may include a soil water introduction step, a drying step, and a finishing step.

As shown in FIG. 5, in the step of introducing dirt water (slip, W) into the receiving space of the mold 100 for the entrance part of the gypsum material composed of a plurality of layers, including the upper mold part, the middle mold part and the base mold part, the soil water (slip, W) slip) may be included.

In the drying step, the soil is introduced and then dried for a predetermined time of about 4 to 6 minutes, so that the moisture in the part in direct contact with the inlet manufacturing frame 100 is absorbed and removed by the inlet manufacturing frame 100. process may be included. Since gypsum has a property of absorbing moisture, the moisture is absorbed into the manufacturing frame 100 in the part in close contact with soil water, and the corresponding part (outer circumferential surface and bottom surface) is dried sidewall and floor with a thickness of about 3.5mm to 4.5mm. walls may occur.

In the finishing step, the upper mold part 200 and the middle mold part 300 are sequentially dismantled and removed, and then the undried parts that exist inside the 'previous stage entrance part' including the side wall (a) and the bottom wall formed by the drying step are removed. It may include a process of removing the bottom wall by flowing undried soil (b), going through a secondary drying process of 15 to 25 minutes, and then punching a hole in a size corresponding to the hole opened at the top through a process. . The reason for the secondary drying process is that a certain level of firmness is required to prevent the sidewall shape from collapsing when the bottom wall punching is removed, and the drying degree is equivalent to that of the main body object 20 so that the two can be well combined with each other is to do

Through these processes, the inlet shown in FIG. 7 can be manufactured.

Thereafter, the inlet portion that has undergone the finishing step may further include a bonding step in which the inlet portion is bonded to the body object dried to a similar degree, and a firing step including a process in which the entire object is dried and fired after bonding.

The upper mold part 200 includes an inlet hole 210 formed through from the top to the bottom so that soil water flows into the soil water receiving space of the middle mold part 300, and the lower diameter of the inlet hole 210 is It may be formed smaller than the diameter of the soil water receiving space. As a result, in the upper mold part 200, as the diameter of the lower end of the upper mold part is smaller than the diameter of the soil water receiving space by a length corresponding to the thickness of the pottery inlet, the upper part of the soil water is directly contacted to help remove moisture from the corresponding part. It may include an upper contact guide portion 211 configured. Based on the side cross-sectional view, the upper contact guide portion 211 may be formed to protrude from the upper end of the soil water accommodation space to the inside of the soil water accommodation space. As a result, the soil water introduced into the soil water receiving space is surrounded by the inner circumferential surface of the middle mold part 300, the upper surface of the base mold part 400, and the upper contact guide part 211 of the upper mold part 200, and is directly surrounded by three surfaces. Moisture is more effectively removed through contact, so that a smooth drying process can be achieved.

The diameter of the upper end of the inlet hole 210 of the upper mold part 200 may be formed to be larger than the diameter of the lower end so that the width gradually decreases from the upper end to the lower end. For example, it may be formed in a parabolic shape. This is for the smooth inflow of soil water (W).

The configuration of the upper mold part 200, the middle mold part 300 and the base mold part 400 will be described in detail with reference to FIGS. 8 to 10 .

The upper mold unit 200 may be disposed at the top of the production frame. The upper mold part 200 may include first to third holding parts 220 to 240 protruding from the lower end thereof and configured to correspond to the mounting grooves of the intermediate mold part 300 below. The first holder 220 protrudes from the edge along the outer circumferential surface, and its cross-sectional shape may be two arcs arranged side by side at regular intervals and including two straight lines connecting both ends of the two arcs. The second holder 230 may be formed to face away from the first holder 220 and face each other so that the upper mold part 200 does not deviate from the middle mold part 300 in either direction. made it possible The width (length of an arc) and thickness (length of a straight line) of the second holder 230 may be smaller than those of the first holder 220 . The second holder 230 and the first holder 220 may be disposed to form an angle of 120° with respect to the center. The third holding portion 240 may be convexly protruded from the bottom of the upper mold portion 200 in a hemispherical shape. This may be coupled to the third mounting groove 340 of the intermediate mold unit 300 to be described later.

The middle mold part 300 may include a first middle mold part 300A and a second middle mold part 300B that can be divided into two parts. The first intermediate mold portion (300A) and the second intermediate mold portion (300B) may be configured to surround the soil water receiving space configured to correspond to the shape and size of the inlet portion in the center. The first intermediate mold portion (300A) and the second intermediate mold portion (300B) are each semicircular, but a semicircular hole is formed in the center of the straight corner portion, and when the two are combined to face each other, the two central semicircular holes are a soil receiving space. It can be configured to achieve. The reason why it is configured as a separable type is to smoothly remove the intermediate mold part 300 without affecting the somewhat dried inlet part (shape deformation by external force, etc.) after the drying step when manufacturing the inlet part.

The middle mold part 300 includes first to third mounting grooves 320 to 340 that are recessed inwardly on the top so as to correspond to the first to third mounting parts 220 to 240 of the upper mold unit 200. can do. A first holding groove 320 may be formed in the first intermediate mold part 300A, and a second holding groove 330 may be formed in the second intermediate mold part 300B facing this, and a hemisphere next to it A third holding portion 340 formed in an inner recess in the form may be formed.

The middle mold unit 300 may include a fourth mounting groove 350 and a fifth mounting groove 360 configured to be correspondingly coupled to the fourth and fifth mounting portions of the base mold unit 400, which will be described later, at a lower portion of the middle mold unit 300. there is. The reason why the mounting grooves are formed on the upper and lower parts of the middle mold part 300 is that they are the most important component in the manufacturing process of the inlet shape, so the upper mold part 200 and the base mold part 400 are located on the outer edges of the mounting grooves. This is to prevent position movement as much as possible even when an unavoidable external force is applied by supporting it through the

The first intermediate mold portion 300A has a first protrusion 300A-1 and a second protrusion 300A-2 formed on both sides of the second intermediate mold portion 300B with a soil accommodating space interposed therebetween. ), and the second intermediate mold unit includes first and second receiving grooves 300B-1 and 300B-2 configured to be correspondingly coupled to the first protrusion 300A-1 and the second protrusion 300A-2. can include

The base mold unit 400 may include fourth and fifth mounting portions 450 and 460 configured to be correspondingly coupled to the fourth to fifth mounting grooves 350 and 360 . The base mold part 400 is disposed at the lower end of the middle mold part 300 and can serve as a base that supports the lowermost part when manufacturing the entrance part, and induces the formation of a bottom wall by supporting the lower end of soil water introduced into the receiving space. It may include a lower contact guide portion 410 to. The lower contact guide part 410 may be the top smooth surface of the base mold part 400, but in some cases protrudes from the top by a size corresponding to the size (diameter) of the soil receiving space in order to adjust the thickness or shape of the bottom wall. Or it may be configured to be recessed inward.

12 is a flowchart of a manufacturing method for manufacturing a manufacturing frame according to an embodiment of the present invention.

A manufacturing method for manufacturing a manufacturing frame as shown in FIGS. 11 and 12 will be described in detail below.

A method for manufacturing a pottery inlet manufacturing frame according to an embodiment of the present invention includes a model manufacturing step (S100) of manufacturing a model inlet, which is a model of the pottery inlet, and an intermediate mold of gypsum material provided to surround the model inlet to correspond to the model inlet. The middle mold part manufacturing step (S200) of manufacturing a part, the base mold part manufacturing step (S300) of supporting the bottom of the model inlet and manufacturing a base mold part that is disposed and coupled to the bottom of the intermediate mold part (S300), and supporting the top of the model inlet, An upper mold part manufacturing step (S400) of manufacturing an upper mold part including an inlet hole formed to allow slip to flow in and coupled to the middle mold part may be included.

The model manufacturing step (S100) may include a process of manufacturing the model inlet 50 made of gypsum material. The inlet of the model may be made larger than the inlet of the actual pottery to be coupled to the ready-made product in consideration of the shrinkage rate of the soil. The size of the model inlet can be determined through the following process. Determine the size (a) of the actual pottery inlet that will fit into the ready-made part (1), and consider the shrinkage rate of the soil in the range of 17.5% to 18.5% at about 18% to determine the size (A) of the model inlet. That is, A*(1-0.18) = a. Here, an accurate value can be derived by considering the allowable tolerance (ex. around 0.1mm) of the numerical value of the off-the-shelf part (1), so the size (A) of the model inlet can be determined by inverse calculation based on this. It may be determined that approximately A=a/0.82. Based on this calculated value, the model inlet 50 can be manufactured. Since the model inlet 50 is literally a model and only needs to consider the size of its outer circumference, it will not be necessary to make a hole in the center.

The intermediate mold part manufacturing step (S200) may include a process of manufacturing the intermediate mold part 300 through a process of arranging to surround it with the manufactured model inlet part 50 interposed therebetween. Based on the model inlet 50, the size and shape of the soil water receiving space to be formed in the center can be determined, and based on this, the above-mentioned two divided components (first and second intermediate mold parts) ) and a process of manufacturing mounting grooves formed in the upper and lower parts may be included.

The base mold part manufacturing step (S300) may then include a process of manufacturing the base mold part 400 formed to support the bottom of the model inlet part 50 and be coupled to the lower part of the middle mold part.

The upper mold part manufacturing step (S400) supports the upper end of the model inlet part 50 and includes an inlet hole formed so that dirt (slip) can flow in, and the middle mold part 300 is coupled to the lower part. It may include a process of manufacturing the upper mold portion 200 configured to be able to.

Through the above steps, the manufacturing frame can be manufactured, and the inlet portion 10 that can be properly coupled to the ready-made part 1 can be manufactured by utilizing the manufactured manufacturing frame.

This embodiment is merely an example of the technical idea of the present invention, and various modifications and variations of this embodiment can be made by those skilled in the art without departing from the essential characteristics of the present invention. It will be possible. This embodiment is not intended to limit the technical spirit of the present invention, but to explain, and therefore, the scope of the present invention is not limited by this embodiment. The protection scope of the present invention should be interpreted according to the claims, and all technical ideas recognized as equivalent or equivalent thereto should be construed as being included in the scope of the present invention.
