Vacuum vibration forming device for manufacturing artificial stones

Abstract

The invention discloses a vacuum vibration forming device for manufacturing artificial stones. The device comprises a box body, wherein box doors are arranged on two sides of the box body; a feed inlet is reserved at the top of the box body; the box body is provided with a vacuumized inner cavity; a packing device is arranged on the upper part, close to the feed inlet, of the inner cavity; a vibration bench is arranged on the bottom face of the inner cavity; and a die is arranged on the inner vibration bench. Due to the adoption of the structure that the packing device and the vibration benchare arranged in the vacuumized inner cavity and the die is arranged on the inner vibration bench, the generation of air holes in stone materials and the subsidence of cured particles are effectively prevented through vacuuming and vibration in a curing and forming process that the mixed stone materials enter the packing device and the die from the feed inlet. The manufactured stone materials haverelatively high rigidity, wear resistance and attractive appearance.

Description

Technical field [0001] The invention relates to an artificial stone production equipment, in particular to a vacuum vibration forming device for making artificial stone. Background technique [0002] The existing artificial stone is mostly made of stone powder and synthetic resin as raw materials, and is formed by solidification in a mold cavity. At present, there are two main production methods for artificial stone. One is manual production. Although the equipment used is relatively simple and labor-intensive, the resin content used is only about 28%, so its production cost is low. The second is mechanized automatic pouring production. This production method has more advanced equipment and automation. Higher, but the resin content is as high as 33%, so its production cost is higher. In addition, when using mechanized production, because the curing agent used is very corrosive, it needs to be shut down and cleaned every two hours, so that mass, high-efficiency production cannot ...

[0002] The production of existing artificial stone mostly uses stone powder and synthetic resin as raw materials, and is a kind of artificial building decoration material formed by solidification in the mold cavity. At present, there are two main production methods of artificial stone. One is manual production. Although the equipment used is relatively simple and the labor intensity is relatively high, the production cost is relatively low because the resin content used is only about 28%. The second is mechanized automatic pouring production. Higher, but the resin content is as high as 33%, so its production cost is higher

In addition, when using mechanized production, because the curing agent used is very corrosive, it needs to be shut down for cleaning every two hours, which makes it impossible to achieve large-scale and high-efficiency production. More importantly, during the curing process In the process, due to the sinking of resin particles and the precipitation of low-molecular liquid, the volume of artificial stone will shrink, the surface will wrinkle and the defects of porosity will lead to uneven overall strength of the product, uneven appearance and difficulty in demoulding.
