A first blank carrier plate 115 is provided on the first conveyor line 112 for conveying the demolded shell blank. The first frame 113 is disposed at a preset position of the first conveyor line 112 for supporting the first grouting mold assembly 111 above the conveyor line. A first carrier assembly 114 is disposed above the first frame 113 for carrying the demolded shell blank from the first grouting mold assembly 111 onto a first blank carrier plate 115.
Fig. 3 is a schematic structural view of an inner blank forming apparatus according to an embodiment of the present application. Referring to fig. 3, the inner green body forming apparatus 120 includes a second slip casting mold assembly 121, a second transfer line 122, a second frame 123, and a second carrier assembly 124. The second slip casting mold assembly 121 includes an outer mold plate for forming the outer surfaces of the seat ring and the liner and a mold shoe for forming the cavity of the liner to form the inner blank in one shot. A second blank carrier plate 125 is provided on the second conveyor line 122 for conveying the inner blanks from which the outer mold plates are removed. The second frame 123 is disposed at a preset position of the second conveyor line 122 for supporting the second grouting mold assembly 121 above the conveyor line. A second carrying assembly 124 is arranged above the second frame 123 for carrying the inner blank, from which the outer mould plate is removed, from the second grouting mould assembly 121 onto a second blank carrying plate 125.
The green body merging conveyor line 200, connected to the conveyor terminals of the first conveyor line 112 and the second conveyor line 122, is configured to receive the outer shell green body and the inner green body and to output the outer shell green body and the inner green body in groups.
The bonding device 300 is provided on the green body joining conveyor line 200, and bonds the outer shell green body and the inner green body by the bonding device to form a finished green body when the outer shell green body and the inner green body are conveyed to the setting position of the bonding device in a group.
In the implementation process, the inner blank body formed by the seat ring and the inner liner at one time is formed through the second grouting die assembly 121, and the complete blank body of the toilet bowl can be obtained only by bonding the outer shell blank body and the inner blank body. The application omits the bonding step of bonding the seat ring and the liner, thereby avoiding the problem that the bonding slurry is easy to block the water outlet on the seat ring blank, and the damage condition of the seat ring blank or the liner blank occurs due to insufficient bonding strength, and simultaneously, the drying time of the blank is shortened and the bonding curing time is only once due to the one-step molding of the seat ring blank or the liner blank.

Referring to fig. 6, after the outer shell blank 10 is disengaged from the first slip casting mold assembly 111 and the inner blank 20 is disengaged from the second slip casting mold assembly 121, it is typically inverted. The inverted outer shell blank 10 is fitted around the inverted inner blank 20 and then the outer shell blank 10 and the inner blank 20 are bonded. After the blank body is dried for a certain time, the finished blank body is turned over by 180 degrees by a blank turning machine, so that the finished blank body is erected. In the implementation process, the blank overturning machine can save manpower.
The bonded finished blank is directly stored on the stripping support plate, and the finished blank is manually lifted to wipe and find the bottom of the blank after being placed for a preset time. Because the wet blank toilet is softer and heavier, the labor intensity of workers and the personnel investment are large during operation. In the above implementation process, the blank turning machine 400 can rotate the wet blank toilet according to a predetermined angle, which is convenient to operate and saves manpower.
In one possible implementation, the conveying section of the blank merging conveyor line 200 downstream of the blank turner 400 is provided with a blank repair station 500. At the trimming station 500, the trimming may be performed automatically by a machine or manually.

In the implementation process, the seat ring and the liner are molded at one time, so that the bonding step of bonding the seat ring and the liner is omitted, and a finished blank can be obtained only by bonding once. Therefore, the high-pressure grouting molding method disclosed by the embodiment can avoid the problem that the water outlet on the seat ring blank is easy to be blocked by bonding slurry, and the damage condition of the seat ring blank or the inner liner blank occurs due to insufficient bonding strength, meanwhile, the method can shorten the drying time of the blank, and shorten the bonding curing time.
The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
