Mold special for post injection molding sandwich compound insulation building blocks

Abstract

The invention discloses a mold special for post injection molding sandwich compound insulation building blocks. The mold comprises an upper mold 1 and a lower mold 2, and is characterized in that theupper mold 1 is composed of an upper connecting plate 101, a lower connecting plate 102, a steam / water chamber square frame 103, a mold frame 104, multiple oil cylinders 107, multiple middle clampingplates 113, two end clamping plates 114, multiple guide shafts 115, multiple guide shaft flanges 108, multiple top steam / cooling water passing net plates 117, multiple side face vertical steam / coolingwater passing net plates 121, multiple large heat-resisting rubber base plates 118, multiple small heat-resisting rubber base plates 119 and multiple top partition plates 120; and the lower mold 2 iscomposed of a lower connecting plate 201, multiple lower mold inner partition plates 202, multiple lower mold outer partition plates 203, multiple lower mold bottom steam / cooling water passing net plates 206, multiple large heat-resisting rubber base plates 118, multiple small heat-resisting rubber base plates 119 and a steam / cooling water chamber 210. The mold is novel in design, reasonable in structure, low in manufacturing cost, high in production efficiency and long in service life.

Description

technical field [0001] The invention relates to a special mold for a post-injection sandwich composite thermal insulation block, which belongs to the field of concrete product processing mold technology and mold production. Background technique [0002] After a period of production practice, the existing special mold for forming composite thermal insulation blocks has exposed some outstanding structural and technical defects, which are mainly manifested in: 1) The partition plate of the upper mold box is fixed and dead, and the 2) Small round aluminum caps with several air holes are used to inlay the left and right fixed partitions, upper top plate and lower bottom plate, which will easily cause air hole blockage and cooling. Water clogging leads to slow temperature rise and long cooling time, resulting in long production cycle and low production efficiency; 3) Due to the clogging temperature of the pores cannot meet the requirements, the strength of the injection-molded pol...

Problems solved by technology

[0002] After a period of production practice, the existing special mold for forming composite thermal insulation blocks has exposed some prominent structural and technical defects, which are mainly manifested in: 1) The partition plate of the upper mold box is fixed and dead, and the 2) Small round aluminum caps with several air holes are used to inlay the left and right fixed partitions, the upper top plate and the lower bottom plate, which will easily cause air hole blockage and cooling. Water clogging leads to slow temperature rise and long cooling time, resulting in long production cycle and low production efficiency; 3) Due to the clogging temperature of the pores cannot meet the requirements, the strength of the injection-molded polystyrene insulation board is low; 4) It is composed of two blocks. The partition at the end is fixed, and there is no gap between the injection-molded polystyrene sandwich insulation board located in the middle of the inner and outer concrete leaves and the fixed partitions at both ends. When the upper mold box rises, it will drive the inner molded The concrete polystyrene sandwich composite thermal insulation block rises together, and it is useless to come out of the upper mold. For this reason, it is necessary to install several lower cylinders on the top of the upper mold box to push the formed concrete sandwich thermal insulation block out of the upper mold box. In this way, although the demoulding of the concrete sandwich insulation block has been realized, damage to the inner and outer leaves of the concrete often occurs, resulting in increased costs and reduced economic benefits
