[0015] Compared with the prior art, the present invention has the following advantages:

[0016] (1) The present invention can be used to pre-process a hollow template with cross holes in the factory quickly and automatically, so that cement can be directly poured into the cross holes during construction, thereby effectively improving the on-site construction efficiency. The structure of the present invention is easy to operate and has high operating efficiency, which can greatly shorten the factory pre-processing time.

[0017] (2) The present invention divides the mold core for forming the transverse core hole into several sections, and sets a core tube cavity in the longitudinal core tube to accommodate the movable transverse core tube. The movable transverse core tube is retractably installed in the longitudinal core tube to ensure that the movable transverse core tube extends out of the longitudinal core tube to form the transverse core hole during casting. When demolding, the movable transverse core tube is retracted into the longitudinal core tube so as to be pulled out of the longitudinal core tube along the length direction of the longitudinal core tube. The installation and disassembly are very convenient. In addition, the straight sections at both ends of the longitudinal core tube are convenient for sealing, and the middle tapered section is convenient for demolding. Multiple movable transverse core tubes are installed on the movable side plates, and driving arms are set to correspond to each movable side plate one by one. When the driving shaft is turned, each movable transverse core tube can be uniformly driven to extend out of the longitudinal core tube, thereby improving the assembly efficiency of the template. The turning of the driving shaft can also be electrically controlled, which is more convenient to use. In addition, when dismantling, the driving shaft can be rotated to make the driving arm away from the movable side plate to avoid interference between the two and affect the dismantling of the longitudinal core tube.

[0018] (3) The molding cavity of the present invention is composed of a front side panel, a rear side panel, a left side panel and a right side panel that are movably spliced ​​with a bottom frame, which is convenient for demoulding, the setting of a support plate, and secondary maintenance. In addition, by setting positioning holes on the bottom frame and positioning columns on the front side panel, the rear side panel, the left side panel and the right side panel, the assembly accuracy is ensured. In conjunction with the I-shaped connecting joints of the front side panel and the rear side panel, when the front side panel, the rear side panel, the left side panel and the right side panel are installed with the bottom frame, it is only necessary to insert the pin and rotate the eccentric sleeve to complete the positioning and assembly of the front side panel, the rear side panel, the left side panel and the right side panel, thereby greatly reducing the difficulty of assembly and improving efficiency.

When the brick-making mold 3 moves to the bottom of the feeding mechanism 4, the feeding motor drives the feeding roller 43 to rotate, and the brick material is put into the feeding hopper 41. After being squeezed and rolled by the two feeding rollers 43, the brick material is evenly fed into the brick-making mold 3. The brick-making mold 3 is feeding the feeding mechanism 4 while moving, and at the same time, the conveying Mechanism 2 will make the brick-making mold 3 vibrate, and the brick-making mold 3 will vibrate during pouring to evenly fill the molding cavity. After the filling is completed, the conveying mechanism 2 will take the brick-making mold 3 away from the feeding mechanism 4 and transport it to the bottom of the grinding roller 52. The grinding roller 52 is pressed on the molding cavity by gravity, and the conveying mechanism 2 continues to drive the brick-making mold 3 to move, thereby ensuring that the grinding roller 52 rolls on the molding cavity from beginning to end to ensure the flatness of the upper side of the brick material, and then the conveying mechanism 2 continues to convey the brick-making mold 3 to complete the automatic pouring and molding.
