[0002] Wood-Plastic Composites (WPC) is a new type of composite material that has been booming in recent years at home and abroad. It refers to the use of polyethylene, polypropylene and polyvinyl chloride, etc., instead of the usual resin adhesive, mixed with more than 50% of waste plant fibers such as wood powder, rice husks, straw, etc. to form new wood materials, and then produced by plastic processing processes such as extrusion, molding, injection molding, etc., to produce boards or profiles. It is mainly used in building materials, furniture, logistics packaging and other industries. The bending and forming of wood-plastic strips is generally to heat the wood-plastic strips to the softening temperature and then put them into the forming mold, and then put the forming mold into water to cool, so that the wood-plastic strips are bent and formed. The applicant disclosed a new type of backrest wood-plastic strip forming mold in the utility model patent application with application number CN202223600482.3. By adding a shaping mechanism, the deformation of the mold during the cooling process is reduced, and the product molding quality is guaranteed. However, with the improvement of the production process, the forming mold can only be cooled in the water in the static mode, and the wood-plastic strips are easy to fall off from the mold during the transfer process after cooling. And the slide groove on the bottom plate is easy to affect the softened wood plastic strip, and it is easy to leave groove marks. Therefore, it is necessary to further improve the wood plastic strip forming mold. Utility Model Content
