Abstract

The invention provides an improved thermosetting molded part production process and an improved thermosetting molded part production mold structure which are invented for improving environmental economic benefits. The production process comprises the steps of preparing a molding material, filling and distributing the molding material, closing, pressurizing and heating molds, molding and curing themolding material into thermosetting molded parts, opening the molds and conducting mold stripping on the thermosetting molded parts. The mold structure is characterized in that the mold is provided with at least one lower mold cavity movable lining made of a good heat conduction material; the lower mold cavity movable linings are filled with the molding material distributed moderately in advance;the lower mold cavity movable linings and the filled molding material are transferred to lower mold cavities, and then the molds are closed and heated; the molding material is molded into the thermosetting molded parts in cavities defined by the lower mold cavity movable linings and upper molds; and then the molds are opened, the lower mold cavity movable linings and the thermosetting molded parts are taken out from the lower mold cavities, and then the thermosetting molded parts are taken out from the lower mold cavities.

Description

technical field

[0001] The invention belongs to the technical field of production of thermosetting molded parts. Background technique

[0002] First introduce molded wood parts: molded wood parts are a kind of thermosetting molded parts, which use suitable particle size wood powder (mainly lignin and / or cellulose components) as filling materials, and thermosetting materials as binders. In the mold, under the action of pressure and heat, the formed wooden workpiece is solidified. Molded wood parts are widely used in furniture, construction, machinery and other fields, and can often obtain the effect of imitating logs.

[0003] The existing production process of molded wood pieces is generally to mix wood powder and binder at room temperature to obtain molded materials, then fill the molded materials into a mold, pressurize and heat, and obtain molded wood pieces.

[0004] In actual production, because of continuous production, the previous molded wooden piece has just come ...
