て定寸に切断して無機質板材を製造する方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an extrusion molding method for an inorganic board material, and more specifically, an inorganic board material is produced by cutting an inorganic original board extruded from a molding die into a fixed size on a template. Relating to a method of manufacturing.

。The production of inorganic board materials such as cement-based extruded building materials is usually
An inorganic original plate that is continuously extruded from an inorganic material molding die is received by a template, the original plate is cut into each template, and then the original plate is cut into a fixed size shape on the template to form the original plate. After adjusting the dimensions, it is subjected to a prescribed curing treatment, and after hardening, it is removed from the template.

ときに型板ごと持ち上がり該原板の変形が生しることが
ある欠点があった。However, when the original plate is cut to size on a template, the cutting pressure may cause the original plate to stick to the template, making it difficult to remove the original plate after the primary curing, and sometimes when the original plate is removed. However, there is a drawback that the entire template may be lifted and the original plate may be deformed.

If a template used to manufacture quality board materials is used to manufacture long board materials, the smoothness of the back surface and surface shape of the product will be impaired.

[Technology that led to the solution of the problem] That is, the extrusion molding method of an aluminium-free plate material of the present invention consists of an inorganic blank plate 4 obtained by continuous extrusion 2 of an inorganic material from a molding die. ．． In the process of being sequentially received by templates and conveyed, the original plate is cut into templates, and then cut into a uniform 1" shape on the template 1-1, shaped 5, and then cured for a prescribed period of time. This is an extrusion molding force method in which an inorganic plate material is produced by applying the treatment and then removing the plate from the J double mold plate.

しない。It is also possible to perform mold release treatment on the entire surface of the template 3, but in that case, the original plate 2 becomes slippery, so there is a risk that the original plate 2 will move unexpectedly during the transportation process from extrusion to curing, causing polymorphism. . However, the mold release process is limited to one cutting locationζ
