Block injection molding equipment and injection molding method thereof

Abstract

The invention relates to building block injection molding equipment, which comprises a gas filling machine, wherein the gas filling machine comprises a gas filling machine rack, a gas filling device which is driven by a power device I to move up and down is arranged on the gas filling machine rack, and the gas filling device comprises a building block hole interior gas filling device and a building block hole upper surface gas filling device. The building block injection molding equipment is provided with the interior gas filling device and the upper surface gas filling device, polyphenyl granules expand, and are adhered and cured due to influence of steam, so as to form integral polyphenyl blocks matching exactly with walls of building blocks, the interior gas filling device can be used for inflating high-temperature steam into the polyphenyl granules of the building block holes, so that the polyphenyl granules in the middle and at the bottom of the building block holes are well expanded, adhered and cured, the upper surfaces of the polyphenyl granules of the building block holes can be filled with gas and pressurized through the upper surface gas filling device, so that the upper-layer polyphenyl granules of the building block holes can be well expanded, adhered and cured, the forming plane is smooth, and the heat-preservation and insulation effects of building blocks can be effectively enhanced.

Problems solved by technology

[0002] At present, in the field of construction, the outer wall or inner wall usually adopts the masonry structure of blocks (also called bricklaying), and the masonry is mostly fly ash plus blocks, which not only wastes and consumes energy, but also has Insufficient thermal insulation, light weight, heat insulation, sound insulation performance, etc., can not meet the requirements of the national building energy conservation. In order to solve the above problems, the hollow blocks are usually treated as follows: 1. Polystyrene board or polyurethane board Cut small pieces with thermal fuses and insert them manually into the holes of the hollow blocks. This method is costly, labor-intensive, and has poor thermal insulation performance. The small blocks of benzene or polyurethane are very regular square, so there must be gaps around them, as long as there are gaps, air circulation will be generated to reduce the heat insulation function; High labor intensity, low output, uneven surface, high dry density, which will cause waste of steel bars in frame structure design; During masonry, the entire concrete protective layer is hung outside the structural column by the polystyrene board, and it is difficult to ensure that the concrete protective layer will not fall off when the polystyrene board degrades, causing accidents; 4. To the hollow block Lightweight materials such as polystyrene particles or polyurethane particles are injected into the holes. In this patent, polystyrene particles are used as an example. This method can better solve the above problems, but most of them are artificially filled with polystyrene particles. In the hole of the block, and then pass high-temperature steam into the hole of the block, the efficiency is low, the foaming is poor, and the heat preservation effect is not ideal

The patent application number 201310401916.3 discloses a block injection molding machine and its use method. In this patent, steam is injected into the completely closed space formed by the steam delivery head, the fixed mold box and the lower template through the steam pipeline through the steam delivery head. The steam instantly penetrates into the hole of the block with polyphenylene particles, making the polyphenylene particles pre-expanded and enlarged again (because the hole space of the block remains unchanged, the polystyrene particles are extruded and condensed) and condense together to form a whole with the block. Using this kind of steam entraining device, during the process of entraining, the polyphenylene particles in the upper layer of the block hole first contact with the steam and become larger instantly, making it difficult for the steam to enter the bottom layer of the block hole, resulting in the polyphenylene particles in the bottom layer of the block hole It is difficult for the particles to re-foam and become larger, and there are large gaps between the polystyrene particles, which makes it difficult for the processed blocks to achieve better thermal insulation effects; in this patent, the aggregate lower silo does not directly feed the blocks, However, the feeding of the distribution vehicle is required, and the distribution vehicle needs to move back and forth on the track, so that the whole process of block injection molding cannot be carried out sequentially on the track, and the injection molding efficiency is low.
