Description

DETAILED DESCRIPTION OF THE INVENTION The conventional method for manufacturing a Western-style toilet bowl body is to form the partition body 8 of the trap 9 in the shape of a wall, as shown in A-F in FIG. b Cast the trap arm 7 in a separately prepared plaster mold, and c adhere the trap wall 7 to the toilet bowl body using mud bran.

That is, this manufacturing method requires three steps, a plaster mold for molding the trap wall, and a considerable amount of skill for mounting, resulting in poor production efficiency. The present invention is intended to manufacture not only the toilet bowl body but also the trub wall and partition of the trough with only one coin-making operation.

The present invention provides protrusions 2, 2 facing each other on the inner surfaces of the two outer molds 1, 1 forming the left and right walls of the toilet bowl, and consists of these outer molds 1, 1, a bottom mold 3, and a middle mold 4. A Western-style toilet that does not require a gluing process (Western-style flushing toilet, Western-style tank with dense stripes) is characterized by pouring mud into a plaster mold and molding the hollow partition 8 and trap ridge 7 of the trap 9 at the same time as the toilet body. The present invention relates to a method for manufacturing the main body of a type flushing toilet, a Western-style siphon toilet, a Western-style tank dense striped siphon toilet, a Western-style siphon jet toilet, a Western-style tank tight-filling siphon jet toilet, etc.

Next, the manufacturing method of the present invention will be explained in detail for the Western-style toilet bowl shown in FIGS. 2A and 2A'.

The left and right outer molds 1, 1 are opposed as shown in Fig. 2 A',
The protrusions 2, 2 are provided so that there is a gap of about 1 skin between the end faces.

There is a gap corresponding to the thickness of the toilet bowl body at the contact portions of the left and right outer molds 1, 1, the middle mold 4, and the bottom mold 3, except for the contact portion between the rising surface and the lower end surface of the outer molds 1, 1. Mold each mold as desired, combine these four plaster molds, and stand upside down with the middle mold 4 facing down.
Mud bran is injected through the mirror inlet 5 of the bottom mold. The mud immediately flows into each space and at the same time passes through the gap between the left and right protrusions 2, 2, flows into the space, and fills all the spaces. Next, by pouring out the slurry from the artificial mud opening 6 for an appropriate period of time, the toilet bowl body is formed by attaching to the plaster mold, and the hollow partition 8 and the trap wall 7 of the trap 9 are also formed to form the trap 9. If the upper and lower surfaces of the protrusions 2 and 2 are rounded, the upper and lower surfaces of the molded cutter 8 will also be rounded, allowing dirt to flow out without being caught. Reference numeral 10 designates a trap port provided by drilling after molding, and reference numerals 11 and 12 designate a water fountain hole and a discharge port, respectively, provided in the same manner.

In addition, even if a gap is provided uniformly between the end surfaces of the left and right protrusions 2, 2, even if they are provided so that some parts are in contact and a gap appears in other parts, the formation of the trap partition will not be possible. Also, mud flows out from the gap into the space. Figure 1A, Figure 2A,

Figures 1F and 2F are a cross-sectional view of a Western-style tank-feeding siphon jet toilet and a cross-sectional view of the toilet body showing the condition in which the fins are inserted. In each figure, 8 indicates the trap. The hollow partition, 7, indicates a trap wall.

In the conventional manufacturing method of the toilet bowl body, only the bottom and top body can be formed using the middle mold and the bottom mold, so the parts such as trap partitions that exist between the top body and the bottom can be molded with the bottom and top body. It was not possible to mold them at the same time.

Therefore, in areas where the top, middle, and bottom three tiers overlap, the bottom and middle tiers are molded at the same time using the middle and bottom molds, and the upper tier is molded in a separate mold and glued together to form the toilet bowl body. ing.
As explained earlier, this manufacturing method required three steps, resulting in poor production efficiency, and the runner-up was that gluing required a fairly high level of skill. However, in the present invention, a protrusion is provided between the middle mold 4 and the bottom mold 3 so as to face the inner surfaces of the left and right side molds 1, 1, so that the three tiers of upper, middle, and lower tiers can be stored at once by the coin. Molded and fired.

In other words, since the top of the toilet bowl, the partition and the bottom of the trap can be molded all at once by pouring, not only is production efficiency very high, but since there are no glued parts, the dimensional accuracy of the trap is improved, resulting in a quality product. It has excellent effects such as As in the conventional manufacturing method, the upper tubular rim 13 of the toilet bowl is molded separately and attached to the toilet bowl body.
