Description

Rubber mold with concave-convex structure

Technical Field

The utility model relates to a rubber mold with concave-convex structure especially relates to a framed for placing vacuum stone aggregate.

Background

The traditional manufacturing process of the industrial synthetic stone needs two forms of upper and lower paper or steel plate moulds. The two types of molds have the following problems in the vacuum stone manufacturing process: first, the mode of using top and bottom paper causes the following effects in the manufacturing process: the use of upper and lower sheets in the manufacturing process under vacuum and vibratory compaction results in a tight fit between the lower sheet and the underlying conveyor belt. A vacuum stone height-dividing mechanism is required to solve this problem. Because strong airflow is generated in the vacuum state, the phenomenon of wrinkling, folding, unevenness and the like of the upper paper can be generated at the moment. The wrinkled and uneven paper is pressed into the vacuum stone slab during the vacuum stone pressing process, and pits or dents occur. At this point, the thickness of the manufactured plate is required to be increased, and subsequent thickness setting and grinding are carried out to grind pits or dents of the upper plate and the lower plate of the vacuum stone to form a plane. Resulting in increased costs and wasted resources. Since the paper itself does not completely wrap the material and there are local gaps. Under the vacuum-pumping state, strong airflow can be generated, and a small amount of materials can be sucked out of the paper, so that the pollution to the machine is caused, and the cleaning cost and the waste of materials are increased. The upper paper and the lower paper are coiled paper, and the requirement on the coiled paper is high because the paper is absolutely flat in the whole production process. Uneven phenomena such as wrinkling and folding of the paper can cause wrinkling and folding or uneven paper to be pressed into the vacuum stone panel. The web paper during pressing is not allowed to wrinkle. And the paper is not allowed to wrinkle during all the pulling runs and the tension during the pulling is correct. If the tension is too loose, the paper can be arched, and if the tension is too tight or uneven, the paper can be wrinkled or pulled in a wave shape. Using upper and lower paper in the condition of drying and curing in the manufacturing process: at the moment, the vacuum stone adopts a high-temperature curing process, and the thermal extension of the material curing forming is larger than that of the paper. There is a possibility that the sheet material is cracked or has bending deformation. In the process of polishing and thickness setting of the semi-finished product, paper on the upper surface and the lower surface needs to be polished. The polished paper needs to be manually disposed, and the paper cannot enter a water treatment filtering pipeline to cause pipeline blockage without being disposed, which can cause the blockage of a ditch. Secondly, the steel plate mould can cause the following influence in the manufacturing process: the steel plate mould can cause the forced vibration and rebound phenomenon of the steel plate in the vibration compaction process. Because the forced vibration and rebound phenomenon can change the particle distribution of the materials distributed before the vacuum stone and cause the problems of increasing the compaction time, difficult compaction and the like, and can cause large reverse impact load to the machine. In the high-temperature curing station of the vacuum stone, the steel plate occupies a certain thickness, so that the curing and forming time at the station is too long (different curing forms can cause that the curing and forming of one plate needs different time from 0.5 to 5 hours).
