Efficient molding plastic mold for wood and plastic wall plate

Abstract

The invention relates to the technical field of plastic molds, in particular to an efficient molding plastic mold for a wood and plastic wall plate. The efficient molding plastic mold comprises an upper mold; the upper mold is fixedly connected with a lower mold through bolts; a columnar slot is formed in the middle position of the upper surface of the lower mold; limiting plates are fixedly connected to both sides of the lower surface of the upper mold; a limiting slot is formed in one side of each limiting plate on the lower mold; the bottom end of each limiting slot is fixedly connected with a plurality of springs; the end, far away from each limiting slot, of each spring is fixedly connected with a connecting plate; a groove located above the columnar slot is formed in the upper mold;the inner top end of the groove is fixedly provided with a heat conducting plate; the lower surface of the heat conducting plate is fixedly connected with a partition plate; a plurality of through holes are fixedly arranged at the top end of the groove; the through holes are uniformly distributed; the end, far away from the groove, of each through hole is fixedly connected with a air guide hole; the through holes are communicated with the air guide holes; two ends of each air guide hole are communicated with the outside; a material guide pipe is arranged on the upper mold. The efficient molding plastic mold is simple in structure and worthy of being popularized.

Description

Technical field [0001] The invention relates to the technical field of plastic molds, in particular to a high-efficiency molding plastic mold for wood-plastic wall panels. Background technique [0002] Wood-plastic composite material is a new type of composite material that has flourished at home and abroad in recent years. It refers to the use of polyethylene, polypropylene and polyvinyl chloride to replace the usual resin adhesive, and more than 50% of wood flour, rice husk, straw, etc. Waste plant fibers are mixed into new wood materials, and then subjected to plastic processing techniques such as extrusion, molding, and injection molding to produce plates or profiles. Mainly used in building materials, furniture, logistics and packaging industries. A board that is formed by hot extrusion after mixing plastic and wood powder in a certain proportion is called an extruded wood-plastic composite board. [0003] Wood-plastic composite board is a kind of wood (wood cellulose, plant...
