Embodiment 2

[0021] This example is to press a synthetic quartz stone sheet with a side length of 125-366cm and a thickness of 1.2-3.0cm. The formula is: 40-75 parts by weight of quartz sand with a mesh size of 5-80; 800-1250 mesh filling fine powder is 15-30 parts by weight; unsaturated polyester resin and saturated resin are 5-15 parts by weight; cullet glass or cullet lens with a particle size of 0.5 cm is 0-20 parts by weight; Stone or light-storing material is 0-5 parts by weight; pigment and curing agent are in proper amount.

[0022] ①The structure of the host

[0023] The structure of the main engine is as follows: the body of the vacuum box (5) is raised and lowered by a pneumatic or hydraulic piston; 2-12 electromagnets (1) are used to install on the side of the bottom plate of the vacuum box (5). The pull-down structure is formed by connecting the pressing tool (3) with a transmission member; the vacuum box (5) is a bell-type structure with a lower opening and a sealing strip o...

Abstract

The present invention is electromagnetic forming apparatus and process of artificial stone. The electromagnetic forming apparatus includes 2-12 electromagnets, one middle iron core driven holddown unit, and one energy storing and releasing spring unit to make the electromagnets generate 100-300 Hz vibration and pressing force under the control of monoway pulse current. The process includes crushing materials including stone containing rich Se, Zn, Sr, Mo and other trace elements, polyester resin, marble and quartz stone; mixing; molding and vibration forming to produce artificial stone article and thin plate with health care function. The present invention has low apparatus cost and high product market value.

Description

1. Technical field [0001] The invention belongs to the field of building materials and building material machinery, and in particular relates to an electromagnetic forming device for artificial stone and a preparation process thereof. 2. Background technology [0002] At present, artificial stone or building decoration material called synthetic granite has a harmonious look and feel and a wear-resistant and non-slip decorative effect due to the transparency of the stone and the artistry of color matching. The three-dimensional imitation jade and agate products made of molds, such as washbasins and flower pots, as well as the solid surface artificial stones that are air-filled and naturally formed in a vacuum box, have formed a certain pattern due to their good ornamental value. market. Domestic and foreign artificial stone vibration forming technology, whether it is block forming or thin plate forming, basically uses a vibrator directly driven by hydraulic transmission or m...
