Description

Technical Field

[0001] The utility model relates to the technical field of mullite thermal insulation brick production, in particular to a mold for producing mullite thermal insulation bricks. Background Art

[0002] Mullite insulation brick is a common building material used for thermal insulation of buildings. It is usually made of mullite and other materials, has excellent thermal insulation and heat insulation properties, and is widely used in construction projects, especially in areas such as walls, floors and roofs that require insulation. This brick can reduce the conduction of temperature inside and outside the building, improve the energy efficiency of the building, and reduce energy consumption. The production of mullite insulation bricks requires molds.

[0003] The Chinese patent publication number is CN213290662U. It discloses a mullite brick blank forming device, which includes a workbench, the upper surface of which is fixedly connected to a mounting frame, and the upper surface of which is connected to a mounting cross plate through two symmetrically arranged first columns. The utility model cooperates with the mounting cross plate, the material receiving plate, the fixed plate and the material blocking plate. After the blank is extruded and formed in the lower forming mold, the material can be directly dropped onto the material receiving plate by rotating the material blocking plate. The operation is relatively simple, and multiple brick bodies can be processed at one time, and continuous production and processing can be achieved, which effectively improves the processing efficiency of the brick bodies.

[0004] With respect to the above-mentioned related technologies, the device has some shortcomings. In actual use, when processing mullite insulation bricks of different thicknesses, it is necessary to replace adapter molds of different depths, which not only increases the complexity of the operation, but also affects the production efficiency of insulation bricks of different thicknesses. Because each mold replacement takes a certain amount of time, and there are certain errors and adjustment time during the operation. In this case, the stagnation time of the production line increases and the efficiency decreases accordingly. Therefore, it is necessary to provide a mold for the production of mullite insulation bricks to solve the above technical problems. Utility Model Content

The movement of the adjusting block 21 drives the extrusion block 5 to move, so that the vertical position of the extrusion block 5 can be easily adjusted by the drive of the motor 9, thereby changing the height of the extrusion block 5 extending to the bottom of the upper die table 4. The extrusion block 5 can flexibly enter the different depths of the lower die 3, thereby achieving the extrusion molding effect of mullite insulation bricks of different thicknesses. Compared with the cumbersome operation of the traditional need to replace different depth adaptation molds, the complexity of the operation is greatly reduced. In addition, since there is no need to frequently change the mold, the stagnation time in the production process is also greatly reduced, and the production efficiency has been significantly improved. It not only improves the flexibility of the production line, but also more effectively meets the needs of diversified and small-batch production, brings new possibilities for the application of mullite insulation brick molds, and promotes the development of the field of building energy conservation.

[0039] After the insulation brick is extruded, the extrusion block 5 is separated from the lower mold 3. At this time, the electric telescopic rod 16 can be controlled to start working. The driving end of the electric telescopic rod 16 drives the push rod 19 to move vertically through the elastic telescopic rod 17. The push rod 19 drives the movable bottom plate 18 to move, so that the movable bottom plate 18 moves upward inside the lower mold 3, and the formed mullite insulation brick is directly ejected, avoiding manual demoulding operations. It not only saves the tedious operation of manual demoulding, but also effectively reduces the labor cost and time consumption in the production process. Compared with the traditional manual demoulding method, this automatic demoulding technology greatly improves the production efficiency of mullite insulation bricks.
