Abstract

A method for manufacturing an artificial stone panel and a mould. The method comprises the steps of: 1) installing a backing plate inside a cavity of a forming mould, wherein the bottom of the backing plate is adhered and fixed to a bottom surface of the forming mould, and a gap is formed on a side of at least one of the four sides of the backing plate so as to form a thickened edge of the artificial stone panel; 2) pasting release paper onto an inner surface of the forming mould and an exposed surface of the backing plate; 3) injecting mixed and stirred raw materials into the mould, performing venting, and smoothing the surface; 4) covering an upper surface of the forming mould with release paper and a mesh spacer, and pushing the forming mould into a vacuum high-pressure machine for flat compaction; 5) taking the release paper and the mesh spacer off of the upper surface, covering a cover plate, and making the forming mould enter a turnover machine to be flipped and demolded; 6) removing a sticker from the bottom of an artificial stone semi-finished product, and then making the artificial stone semi-finished product enter a curing machine for heating and curing and shaping; 7) performing cutting and shaping after curing and shaping; 8) performing surface polishing; and 9) applying a protective film to a surface of a finished product. The present invention has the beneficial technical effect that the thickened edge of an artificial stone table top is bond-free, and same is efficient, integrally formed, and more aesthetically pleasing.

Description

A kind of manufacturing method and mould of artificial stone panel

technical field

The invention belongs to the field of building materials, and particularly relates to a manufacturing method and a mold of an artificial stone panel.

Background technique

The thickening structure of the front edge of the existing artificial stone countertops of kitchen cabinets is made by stacking and thickening artificial stone panels or 45-degree angle splicing and splicing with glue. sanded.

The existing above-mentioned technological process is complicated, and it is difficult to guarantee the quality. Since it is difficult to adjust the color of the glue to be exactly the same color as the artificial stone, after a long time, there will generally be traces of the same line at the splicing, which will affect the appearance. Due to manual operation, it is difficult to ensure 100% straightness in the cutting of the thickened plate, and the size of the panel and the baffle is relatively long, and the glue will be unevenly applied, which makes the splicing of the panel and the thickened plate difficult. To achieve uniform connection, easy to deform, affect the appearance, heavy grinding workload, pollute the site environment, and the production efficiency is also very low.

To sum up, the existing front-end edge thickening process of artificial stone panels has the following problems:

1. The process is complicated and the efficiency is low;

2. The bonding gap is broken and the surface is beautiful.

SUMMARY OF THE INVENTION

The purpose of the present invention is to improve the processing efficiency of the artificial stone edge thickening process and solve the problem that the artificial bonding seam affects the appearance.

In order to solve the above-mentioned problems, the present invention proposes a method for making an artificial stone panel, the specific process of which is as follows:

1) Add a backing plate inside the forming mold of the flat cuboid inner cavity, the bottom of the backing plate is fixed with the bottom surface of the forming mold, and at least one of the four sides of the backing plate and the side of the forming mold leave a gap to form the thickening of the artificial stone panel edge;

2) Paste release paper on the inner surface of the forming mold and the exposed surface of the backing plate;

3) Inject the mixed and stirred raw materials into the mold, and shake manually or mechanically to smooth the surface;

4) Cover the upper surface of the forming mold with release paper and mesh, and push the vacuum high-pressure machine for flattening and compaction;

5) Remove the release paper and mesh spacer on the upper surface, cover the cover, and enter the turning machine to flip and demould;

6) Remove the bottom sticker of the semi-finished product of the artificial stone panel, and then enter the curing machine to heat and cure;

7) Cut to shape after curing and shaping.

Preferably, the backing plate inside the forming mold can be one piece or multiple pieces that can be easily combined, and there is a gap between the edge of each backing plate and other backing plates or the side of the forming mold according to the needs to form artificial stone. Thickening of the edge of the countertop.

A manufacturing mold for artificial stone panels, comprising a forming mold and a backing plate; the forming mold is a container with a flat cube cavity; the backing plate comprises one or more pieces and is fixed on the bottom of the forming mold cavity , at least one edge of each backing plate and other backing boards or the side edges of the forming die is left with a gap for forming the thickened part of the edge of the artificial stone panel.

To sum up, the present invention has the following beneficial technical effects:

1. The thickened edge of the artificial stone countertop does not need to be bonded, saving labor and high efficiency;

2. One-piece molding is more beautiful.
