Mould without hindering pearlstone slurry expansion

Abstract

The invention belongs to the technical field of the building material production device, which relates to a mould without hindering pearlstone slurry expansion. The mould comprises an upper base plate and a lower base plate, wherein four side walls are formed by inserting two male wall plates and two female wall plates onto the side edges of the upper base plate and the lower base plate in a but joint mode; eight U-shaped clamps are respectively clamped on the corresponding parts of eight side edges of a square; the upper base plate, the lower base plate and the four side wall plates of the mould are all provided with air exhaust holes to bring convenience for air overflowing during drying; the upper base plate and the lower base plate are in the symmetrical structure; the peripheries of the outer side surfaces of the upper base plate and the lower base plate are provided with U-shaped locking bulges with convex structures; and the parts on the periphery of an inner chamber, which correspond to holes on the wall plates, are respectively fixedly clamped with the U-shaped clamps to form a stable mould body with six ventilated side surfaces. The mould has the advantages of novel structural design, mature technology, low manufacture and production cost, high efficiency, and obvious economic benefits. The thermal insulation material manufactured by the mould has the advantages of reasonable structure, favorable thermal insulation performance, long service life and environmental protection and is flexible to install and operate.

Description

Technical field: [0001] The invention belongs to the technical field of building material production equipment, and relates to a mould, especially a mould, which does not hinder the expansion of perlite slurry. Background technique: [0002] The existing perlite insulation board material and its production technology are to extrude the material in the wet state in the mold under external force, and then dehydrate and dry. The molds used in the production of perlite insulation board are all demoulding methods in wet state And prepared, and the material after demoulding in wet state is vulnerable to damage, and after external force extrusion molding, the profile can only be a very dense structure, which will affect the heat preservation effect; and when external force extrusion molding , the shape of the finished product should not be too complicated, so as not to limit the application range and convenience of perlite insulation profiles; if the mold used in the prior art is d...

[0002] The existing perlite insulation board material and its production technology are to extrude the material in the wet state in the mold under external force, and then dehydrate and dry. The molds used in the production of perlite insulation board are all demoulding methods in wet state And prepared, and the material after demoulding in wet state is vulnerable to damage, and after external force extrusion molding, the profile can only be a very dense structure, which will affect the heat preservation effect; and when external force extrusion molding , the shape of the finished product should not be too complicated, so as not to limit the application range and convenience of perlite insulation profiles; if the mold used in the prior art is dried together, it will be difficult to demould after the perlite insulation board is completely dry, and the molding will be complete. and because of the high friction on the inner wall of the mold, during rapid drying and dehydration, the perlite material sticks to the inner wall of the mold and cannot move freely, resulting in the destruction of the structural integrity of the perlite material and the resulting Physical indicators such as strength decline are affected and other issues
