Dry-wet forming method and device for an artificial stone

Abstract

The invention discloses a dry-wet forming method for an artificial stone. The dry-wet forming method comprises the following steps: I, preparing a forming cavity, wherein the upper end of the forming cavity is open, and a rubber layer covers the inner bottom surface of the forming cavity; II, pouring cement paste into the forming cavity; II, pouring dry hard concrete into the forming cavity in the step II; and IV, pressing materials: performing downward extrusion forming on semi-finished products in the forming cavity in the step III by adopting a pressure plate; and V, de-molding and maintaining, thereby obtaining the artificial stone made of the cement paste and the dry hard concrete. Compared with the prior art, the artificial stone, which has a dry hard concrete surface on one side and a cement paste surface on the other side, can be formed, so that the problems that manufacturing efficiency is low due to long reuse time of a forming mould totally manufactured by cement paste in a wet-process forming method and the decorative effect is poor due to the fact that artificial stone, which is totally manufactured by the dry hard concrete, is rough in surface in a dry-process forming method are solved. The invention further discloses a dry-wet forming device for the artificial stone.

Description

technical field [0001] The invention relates to a molding method and a molding device for concrete stone, in particular to a molding method and a molding device for artificial stone. Background technique [0002] Existing artificial stones, such as curbstones, generally only have two molding methods, that is, wet method or dry method. The specific operation of the wet method is: pour the cement slurry into the molding mold, and wait until the molding mold is filled. After curing, the cement slurry in the forming mold can be demoulded after the dry material; the specific operation of the dry forming method is: mix stones, cement and sand into the dry hard concrete, and then pour the concrete into the forming mold for vibration It can be demoulded after vibration and molding. In this wet forming method, the surface of the formed artificial stone is smooth and the decorative effect is good. However, it is necessary to wait for the cement slurry to dry before demoulding, which ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a dry-wet molding method of artificial stone, which solves the problem of low production efficiency caused by the long re-use of the forming mold of the wet molding method in the prior art and the surface of the artificial stone formed by the dry molding method. The problem of poor decorative effect due to roughness

[0005] Another object of the present invention is to provide a dry-wet molding device for artificial stone, which solves the problem of low production efficiency caused by the long re-use of the molding dies of the wet molding method in the prior art and the artificial stone formed by the dry molding method. The problem of poor decorative effect due to rough stone surface
