Abstract

The invention relates to a mould opening and closing mechanism of a wood-plastic board injection machine, which is characterized in that the mould opening and closing mechanism comprises an upper fixed moulding board and a lower fixed moulding board which are connected by a pull rod; a moving moulding board is arranged on the lower moulding board; a moulding board is arranged on the moving moulding board; charging holes are manufactured in the upper fixed moulding board and are matched with an injection head; a mould bolster is arranged below the upper fixed moulding board and is matched with the moulding board; a mould closing oil cylinder is arranged on the lower fixed moulding board or the upper fixed moulding board; a piston of the mould closing oil cylinder is connected with the moving moulding board and drives the moving moulding board and the moulding board; a mould opening oil cylinder is arranged on the upper fixed moulding board or the lower fixed moulding board; jacking blocks are arranged on both sides of the moving moulding board and are connected with a jacking rod of the mould opening oil cylinder. The scheme injects and forms wood-plastic boards in an injection structure mode, and has the advantages of high forming speed, short cooling time, uniform product specification, high density, good quality and improved production efficiency.

Description

technical field [0001] The invention relates to an injection molding machine, in particular to a mold opening and closing mechanism of an injection molding machine for producing thin products such as wood-plastic boards. Background technique [0002] Wood-plastic panels have good physical and chemical properties and mechanical processing properties, waterproof, anti-corrosion, moth-proof, anti-static, flame-retardant, impact-resistant, high-strength, wear-resistant, non-deformable and other characteristics, and can also be sawed, planed, drilled, nailed , the surface can also be painted (sprayed) paint, etc., very popular in the market. Existing wood-plastic panels are generally made of wood powder (sawdust, straw, etc.) and waste plastics (new plastics), which are extruded by an extruder or formed by hot pressing. The products extruded by the extruder have many defects, the specifications are not neat, and the production speed is slow; the products formed by the hot press ...
