Organic glass blowing, drawing and thermal-forming equipment

Abstract

The invention relates to organic glass blowing, drawing and thermal-forming equipment. The organic glass blowing, drawing and thermal-forming equipment comprises a vertical machine body, wherein the machine body is equipped with four vertical guide posts; an upper mould and a lower mould are mounted in the machine body; four corners of the upper mould are separately connected onto the four guide posts in a penetrating mode; the upper mould is driven by an upper cylinder to slide up and down along the guide posts; a vertical main cylinder is mounted on the bottom of the lower mould; the lower mould is pushed by a main cylinder to move up and down; the upper mould is equipped with a semispherical cavity which is downwards sunken; the lower mould is in the shape of a hemispheroid which is symmetrical with the semispherical cavity; when closed, the upper mould and the lower mould form the semispherical cavity; a workbench fixed to the machine body is arranged between the upper mould and the lower mould; a sealing sleeve is mounted on the center of the workbench; the sealing sleeve passes through the center of the workbench; a flange surface is arranged on the top of the sealing sleeve; the flange surface is fixedly connected with the top surface of the workbench; the lower mould is mounted in the sealing sleeve and ascends and descends up and down in the sealing sleeve; an opening is formed in the top of the sealing sleeve; the bottom surface of the sealing sleeve is in sliding seal with an extending-out shaft of the main cylinder; and a gas inlet and a gas exhaust valve are separately arranged on the side wall of the sealing sleeve.

Description

technical field [0001] The invention relates to the field of organic glass, in particular to an organic glass blowing thermoforming equipment. Background technique [0002] Plexiglass is made of methyl methacrylate monomer through specific chemical molecular design and modification, polymerization reaction and high temperature treatment. Its products have the advantages of high bending strength, good impact resistance, good light transmission, good chemical stability, and good weather resistance. Plexiglass hemispheres, plexiglass balls and other shapes of plexiglass cover products have been widely used in commercial, light industry, construction, chemical and other fields, such as lampshades, lighting covers, dust covers, protective covers, aquariums, craft products Wait. At present, the production of hemispherical plexiglass is usually by blow molding or stretching. The plexiglass produced by this method is not stretched uniformly, resulting in uneven light transmission ...

AI Technical Summary

Problems solved by technology

At present, the production of hemispherical plexiglass is usually by blow molding or stretching. The plexiglass produced by this method is not stretched uniformly, resulting in uneven light transmission and defective shapes.
