Special mould applicable for performing construction of spraying insulating mortar at door and window opening

The invention discloses a special mould applicable for performing construction of spraying insulating mortar at a door and window opening, and relates to a novel tool which is developed to solve a backward technology that the insulating mortar used at the door and window opening is still constructed following a purely-manual ponderous plastering mode at home and abroad. The mould is novel in structure; two clamping mechanisms are realized in an integrated manner; the practicality is high; rigid polyvinyl chloride is adopted for injection moulding; the machining is easy; the cost is low; and the mould can be repeatedly used. A template matched with the mould for use is a flame-retardant extruded polystyrene plate or polyvinyl chloride pinch plate; and the mould is scientific and reasonable, and a problem in mechanical spraying construction at the door and window opening is well solved. The mould is successfully developed, so that the construction technology of spraying the insulating mortar or cement mortar can be improved to a new level.
