Wood and plastic co-extruded door pocket adjusting plate extrusion die

Abstract

The invention discloses a wood and plastic co-extruded door pocket adjusting plate extrusion die. The die comprises a die head, long screws, a transition plate, a supporting plate, a cylinder manifold, a mouth die plate, a cooling water jacket 1, a cooling water jacket 2, short screws and a core rod group, the middle position of the mouth die plate is provided with a mouth die hole, the right side surface of the mouth die hole is provided with two up-and-down symmetrical left-facing projections, the middle position of the right side surface of the mouth die hole is provided with a horizontal groove, the middle position of the lower side surface of the mouth die hole is provided with a wide boss, the middle position of the left side surface of the mouth die hole is provided with a right-facing projection adapting to the horizontal groove in size, and the core rod group comprises two rectangular core rods I, two rectangular core rod II and three small rectangular core rods. Wood and plastic co-extruded door pocket adjusting plates processed through the die have the advantages of convenience in assembling and mounting, no deformation, less material consumption, light weight, good anticorrosion and flame-retardation performances, good safety and environmental protection, low cost and long service life.

Description

technical field [0001] The invention relates to an extrusion die, in particular to an extrusion die for a wood-plastic co-extrusion door cover adjusting plate. Background technique [0002] Most of the existing door covers are made of pure wood, and adopt a fixed-width structure without adjusting plates. In this way, on the one hand, for different types of door covers, because of their different widths, they need to be made separately, often resulting in a backlog of products. On the other hand, it needs to consume more and increasingly scarce timber resources, which is not only costly, labor-intensive and time-consuming to make, but also easily deformed by moisture or rot, has a short lifespan, is flammable, and has poor safety. Contents of the invention [0003] The purpose of the present invention is to provide a wood-plastic co-extruded door cover with processed door cover adjustment plate that is easy to assemble, does not deform, consumes less material, is light in w...
