Abstract

The invention discloses a merging core for extrusion moulding machine, characterized in that the merging core is provided with a guide pore, the cavity of which is provided with a guide device which can either be straight grid tray or broken line gird plate, and which can also be vertical tooth-staggered grid tray; the guide pore can also be conic, and the width of inlet ends of grid pores between the straight grid trays is larger than the width of outlet ends. As a component for wood-plastic composite extrusion moulding equipment, the merging core can enhance the quality of articles and is suitable for the extrusion moulding of wood-plastic composite extrusion moulding machine.

Description

technical field [0001] The invention relates to components for extrusion molding equipment, in particular to a confluence core for extrusion molding machines. Background technique [0002] Wood-plastic composites are derived from modified plastics, but the processing requirements of wood-plastic composites are very different from plastics. However, existing wood-plastic composite material processing equipment, such as wood-plastic composite material extrusion molding machinery, basically adopts the structure of existing plastic processing machinery. Practice has proved that, as a new type of material with independent characteristics, the processing technology of wood-plastic composite materials is far more difficult than that of ordinary plastic products, and the production equipment is becoming more and more specialized and specialized. The deficiencies of existing equipment are: [0003] During the extrusion process of wood-plastic composite materials, the arrangement of...
