Description

Fireproof door core board pressing device Technical Field The utility model relates to the technical field of fireproof door core plate pressing devices, and particularly discloses a fireproof door core plate pressing device. Background The fireproof door core plate is used as a core component of a building fireproof isolation system, and the density uniformity, the thermal stability and the molding quality of the internal filler directly determine the fire resistance limit performance of the product (according to the standard requirements of GB 12955-2008 fire door). The existing fireproof door core plate pressing device mainly adopts a single-station integrated structure and mainly comprises a frame, a die assembly, a hydraulic driving system, a filling mechanism and an external heating module, wherein the typical operation flow is as follows: after an operator inputs silicate/perlite mixture into a bin, the mixture is conveyed into a die cavity through gravity or spiral, then a hydraulic cylinder drives a pressing plate to apply pressure and assist external heating, and finally demoulding is completed through an ejection mechanism. In the operation process, the working procedures of filling, compaction, pressing, demolding and the like are sequentially completed through a single station, so that the production efficiency is limited, and in addition, a material filling mechanism is not arranged, so that the pressing is uneven, and therefore, a fireproof door core plate pressing device is needed to solve the problem.
