The present inventor finds following problem when researching and developing product of the present invention and trial product: one, because thermal insulator is usually located at load-bearing matrix " middle part ", therefore, when load-bearing matrix carries out slip casting, grouting port is in certain side of thermal insulator usually, like this, the thermal insulator that density is relatively little will produce the phenomenons such as floating, skew when load-bearing matrix injects, and have impact on the inner constructional form of building block and the positional precision of thermal insulator after load-bearing matrix foaming greatly, thus bring high scrap rate; Two, for ensureing the volume after the foaming of load-bearing matrix, when injecting load-bearing matrix slurry, as the injection rate (especially injection rate shortcoming) of out of true metering slurry, be difficult to the crust 20 (crust: the part of the end face that the rear spilling load-bearing matrix that namely foamed specifies forming " effectively " more than moulding box end face; Effective: namely the root edge of crust should greater than or equal to the height of moulding box upper limb), product can be caused to occur the incomplete situation of end face (namely as shown in figure 12, the root edge of crust 20 is lower than the height of moulding box 3 upper limb, after crust 20 excises, by directly causing, the end face of load-bearing matrix 2 is imperfect, unfairness, and then brings high rework rate and scrap rate).
For the problems referred to above two, this case takes following measures: should for the good injection rate of different volume computing, equal the height of moulding box 3 upper limb for minimum (as shown in figure 13) with the root edge of crust 20 formed, with the root edge of the crust 20 formed a little more than the height of moulding box 3 upper limb for optimum (as shown in figure 14); Finally after load-bearing matrix 2 has foamed, crust 20 is excised, guarantee the integrity of product end face.
To this, for solving the problem one, two, the rotating driving device of the die cap that can rotate around the center of circle of described circumference and the center of circle being positioned at described circumference has been set up in this case on the basis of traditional moulding box; Specifically:
