Moveable mould

Abstract

The invention relates to a moveable mould. The moveable mould comprises an outer mould frame, a lower template and a tray and is characterized in that roller wheels are arranged on the outer side of the lower part of the lower template uniformly; bosses are distributed on the upper surface of the lower template uniformly; through holes for separation are symmetrically formed in the upper surface of the lower template; through holes matched with the bosses of the lower template in position and shape are formed in the surface of the tray, so that the tray can be buckled on the lower template; the bosses and the tray form an integrated plane; the outer mould frame is formed by mould frames on four sides in an enclosing manner; a cavity is formed in the middle of the outer mould frame; the section of the cavity is as same as the orthographic projection of an expanded perlite plate product; the upper part of the lower template is in clearance fit with the cavity of the outer mould frame and is placed in the cavity; and the outer mould frame and the lower template form a groove-shaped shell with an upper opening. The moveable mould has the advantages of simple structure and work reliability, and can improve the production efficiency and the quality of perlite plates and easily realize production automation of the expanded perlite plates.

Description

technical field [0001] The invention belongs to the field of moulds, in particular to a movable mold for processing expanded perlite slabs. Background technique [0002] Expanded perlite board is divided into two types: expanded perlite insulation board and expanded perlite sound-absorbing board, both of which are made of expanded perlite as aggregate, mixed with inorganic cementitious materials and admixtures, and then pressed and dried . Expanded perlite thermal insulation board is mainly used for external wall insulation of buildings, and expanded perlite sound-absorbing board is mainly used for ceilings and inner walls of public buildings and civil buildings, for decoration and noise reduction. In the process of processing, the expanded perlite wet material is still a bulk material after the expanded perlite is mixed with inorganic cementitious material and admixture evenly, and the expanded perlite wet material needs to be put into the mold for pressing. Most of the e...

Problems solved by technology

However, there are disadvantages in this production method, that is, the mold is placed under the upper die punch, the space is limited, and it is extremely inconvenient to fabricate by hand and by machine. In addition, the bottom of the mold is fixed to the outer frame, so it is difficult to achieve production. Expanded perlite board requires multi-layer fabric requirements

It can be seen that the existing technology uses a large amount of manual labor to increase the labor intensity of workers, and the low production efficiency has seriously affected the large-scale production of expanded perlite slabs, and the product quality is also difficult to guarantee.
