Description

[Detailed explanation of the invention] (Field of industrial application) This invention mainly relates to the center ball of a mold for wet split tile molding, and more specifically, the center ball body and split corner for forming both soles are fitted and removed. This invention relates to a middle ball of a mold for wet tiles that is flexible and compatible.

(Prior art) Conventionally, wet-formed tiles are easier to handle by molding two tiles together, and are less likely to bend or deform due to drying and firing, so regardless of the size of the tile. Normally, two tiles are made together like this and split into two after firing, resulting in a split tile.

As shown in FIG. 1, the conventional center balls that form the shape of the tile soles in this die mold for wet tiles are upper and lower sole foot molding portions 3a, 4a that constitute the center ball body 1a that is combined with the stand 2a. Split angles 6a, 6a were integrally provided on both left and right sides of the joining part 5a where the parts are joined.

Therefore, the molded tile body 13 shown in FIG. 2, which is made of two pieces using this medium ball, has the soles 17, 17 on both sides connected at the connection part 16 with the gap S, and is made of two double tiles. 15, 15 are together.
After firing this, divide the two tiles 1 at the dividing line 14.
It is divided into 5 and 15 parts.

(Problem that the invention aims to solve) However, in the conventional medium ball described above, the split corner is integrated with the main body of the medium ball, so if the split corner is easily worn out or damaged, the entire ball must be discarded. It was extremely uneconomical as it had to be disposed of and replaced with a new one. Furthermore, it was not possible to increase the strength by hardening only the easily damaged split corner, or to make it into a different strong material.

In particular, since wet tile is a split method (two pieces put together), burrs appear on the split corner, so it is desirable to reduce the thickness of the split corner as much as possible. There was a problem that significantly shortened the service life.

(Means for Solving the Problems) This invention was made to solve the above-mentioned conventional problems, and is constructed as follows.

In other words, the center ball of the mold for wet tiles of this invention has a center ball body with a fitting hole provided in the combined part where both sole molding parts are combined, and a center ball having a split corner on both sides, which can be freely inserted into and removed from the fitting hole. and a fitting body, which are fitted and fixed in a compatible manner.

Next, the inner ball of this devised wet-type tile mold will be described in detail below with reference to the drawings in terms of embodiments.

〔Example〕

First, reference numeral 1 is a center ball main body in which a fitting hole 10 is provided in a combined part 5 where back-to-back dovetail molded parts 3 and 4 are combined, and a stand 2 is integrated therein. Reference numeral 7 denotes a fitting body that can be fitted and removed into the fitting hole 10 having split angles 6, 6 on both sides, and the fitting body 7 has a wing plate shape with a central boss portion 8 having a boss hole 9 in the center. It is configured. And the middle ball body 1 and the fitting body 7
They are fitted and fixed in a compatible manner. That is, in the embodiment, the fitting body 7 is fitted into the fitting hole 10 of the medium ball main body 1, and the bolt 12 passed through the boss hole 9 of the fitting body 7 is inserted into the screw hole 11 provided in the center of the medium ball main body 1. The fitting body 7 is integrally fixed to the inner ball body 1 by screwing.

(Effect of the invention) As mentioned above, the medium ball of this invention is designed so that the medium ball main body and the fitting body having split angles on both sides can be freely fitted and removed to provide compatibility, and are fitted and fixed. ,
If the split corner is worn out or broken, it is only necessary to replace the split corner fitting with a new one instead of discarding the entire center ball as in the past, which is extremely useful economically.

In addition, since they are compatible, it is possible to replace only the split corner fittings that are prone to wear and tear with ones that are made stronger by quenching or made of a stronger material. In particular, since it is a split (two pieces) method, burrs appear on the split corner, so it is desirable to reduce the thickness of the split corner. It has the outstanding effect of eliminating this drawback by making only the split angle stronger.
