Abstract

PURPOSE:To understand the product number of a retaining mold and to certainly perform automatic control by mounting a waterproof communication memory card on the retaining mold and providing the communication part with the memory card at the position in front of the branch part on a track. CONSTITUTION:The retaining frame stored in a retaining mold storing device is automatically taken out by the command from a control chamber C and placed on a retaining mold loading vehicle to be moved on a retaining mold feed line 11. The signal of the retaining mold is obtained from the communication part 8 provided at the forward position of a cast branch line 32 to determine a pressure cast molding device to which this retaining mold must be arranged. The count signal from the waterproof communication memory card M of the retaining mold is judged and the retaining mold large in the use number of times, low in the number of elapsed days after use or large in the number of times of trouble is determined as an used one to be sent to the retaining mold storing device or the corner of a flaw retaining mold. A necessary number of molded bodies of a necessary product name are molded by the indication of the control chamber C.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mold part number discriminating mechanism of a pressure casting molding apparatus for molding a material such as sanitary ware before firing.

[0002]

2. Description of the Related Art Sanitary ware represented by toilet bowls and washbasins is manufactured by firing a raw material formed by a slurry casting method. A technique of performing pressure casting at the stage of casting the molded body has been conventionally known. For example, JP-A-3-69313, JP-A-3-67604, JP-A-3-69304, JP-A-3-81103, and JP-A-3-67.
The technique is disclosed in Japanese Patent Laid-Open No. 605 or Japanese Patent Laid-Open No. 3-83608.

[0003]

The method of casting sludge will be described. It is characterized in that the raw material clay powder and the like are dissolved in a sufficient amount of water to form a dispersion suspension state, and so-called sludge is absorbed inside the mold. A plaster or a porous resin layer having continuous pores is used as the slurry template. Since the plaster forming the mold has water absorbability, it sucks the sludge, absorbs the water in the sludge, and causes the clay content to adhere to the molding surface of the mold. For small-quantity production, a mold is manually assembled into a mold, sludge is poured into the mold, left to stand, and the mold is removed to obtain a molded body. After that, the molded body is dried, a glaze is applied, and the molded body is baked.

However, in the case of mass production, continuous molding cannot be performed with conventional water absorption by a gypsum mold. Therefore, as described above, a mold made of a porous synthetic resin layer having continuous pores is used as a machine. It can be set automatically, and the slurry is automatically poured into the mold, and pressure is applied from both the mold and the slurry to force the porous resin layer to absorb the water and to cause infiltration. The molding method is used. The present invention, in the pressure casting apparatus described above,
Since there are many forms that can be automatically conveyed for the assortment of sanitary ware, it is necessary to determine whether a predetermined form has been conveyed, and whether to transfer it to the pressure molding line, or It is necessary to determine whether or not the device is to be stored in the storage device. The present invention surely makes this determination.

[0005]

The problems to be solved by the present invention are as described above, and the means for solving the problems will be described below. That is, in the configuration in which the mold unmanned transfer track, the pressure casting molding device and the molded product transfer line are arranged side by side, and the branch part to the pressure casting molding device or the mold storage device is provided on the running track of the formwork carrier. A waterproof communication memory card is attached to the mold, and a communication section with the waterproof communication memory card is provided at a position in front of the branch portion on the track.

[0006]

Next, the operation of the present invention will be described. In response to a command from the control room C, the formwork stored in the formwork storage device is automatically taken out and placed on the formwork carrier 30.
This is moved on the mold conveying line 11. Then, the communication unit 8 provided in the middle portion obtains a signal of the mold to determine in which pressure casting manufacturing apparatus the mold should be arranged. In addition, by judging the count signal from the waterproof communication memory card M of the mold, the one that has been used a lot, the one that has a short number of days after use, and the one that has a large number of failures are determined not to be used. , To the corners of the formwork storage and defective formwork. And control room C
According to the specification, the required number of molded articles 1 having a required product number are molded.
