Mould of extrusion moulding building internal corner plastic template

Abstract

The invention discloses a mould of an extrusion moulding building internal corner plastic template, which is characterized in that a lower template is fixed on a bottom template; and upper template is arranged above the lower template; the working surface of the lower template is convex like a right angle, and the working surface of the upper template is concave like a right angle; the lower template is provided with a concave rib groove; an internal corner cavity is formed by the lower template and the upper template; both sides of the bottom template are provided with racks; a plurality of bottom templates form a track shape through connecting pieces, the upper template is fixed and immovable, and the lower template moves with the track shape formed by the bottom templates; each bottom template is provided with a thimble; the upper template is provided with a spout; and the spout is butted with a nozzle of an extruding machine. The mould continuously produces the building internal corner plastic template with horizontally and longitudinally crossed ribs or abnormal-shaped ribs by effectively using the extruding machine, thereby greatly increasing the production speed and the production quality; in addition, the invention solves the lasting, complex and hard-to-solve problem that the extruding machine can not continuously produce the plastic template with the crossed ribs by continuously producing the plastic template with multiple rib shapes.

Description

technical field [0001] The invention relates to a mold for a plastic building formwork, and more particularly to a mold for extruding a plastic formwork for building inner corners. Background technique [0002] At present, the internal corner formwork of buildings is mainly made of wood, wood boards, and metal formwork. The service life of wood and wood boards is short and the waste of resources is large, so it is not recommended; the metal formwork is difficult to demould, easy to deform, and has a short service life. The waste and consumption of resources is relatively large, which is no longer advocated by the state. Especially building internal angle formwork still adopts the metal formwork of making specially or the carpentry formwork of making specially at present. Plastic formwork for construction is a formwork that has emerged in recent years. It is made of plastic and has the advantages of long service life, easy demoulding, and high recycling.

AI Technical Summary

Problems solved by technology

But at present, there is no special continuous production mold for the plastic formwork of the inner corner of the building. Therefore, it is necessary to explore a special mold for extruding the plastic formwork of the inner corner of the building.
