Extrusion mold for artificial marble composite decoration door frame architrave sectional material

Abstract

The invention discloses an extrusion mold for artificial marble composite decoration door frame architrave sectional material. The extrusion mold comprises a mold body, a transition plate, a support plate I, a support plate II, a confluence plate, a neck mold plate, a water jacket I, a water jacket II, a rear core rod set, a front core rod, a plurality of long screws and a plurality of short screws, wherein a main material feeding inlet is formed in the right side of the mold body. The extrusion mold is characterized in that the rear core rod set comprises a large round core rod and four small round core rods, and the middle of the large round core rod and the middles of the four small round core rods are each provided with an axial ventilation hole; a neck mold hole is formed in the middle of the neck mold plate; three rectangular protrusions are arranged on the bottom surface of the neck mold hole; and a co-extrusion material feeding inlet is formed in the confluence plate. A core portion round hole of the door frame architrave sectional material processed through the extrusion mold is small in deformation and free of bubbles on the inner surface, artificial marble treatment can be carried out on the outer surface of the door frame architrave sectional material, and the door frame architrave sectional material is low in cost and long in service life.

Description

technical field [0001] The invention relates to a plastic mould, in particular to a marble-like composite decorative door frame sheathing profile extruding die. Background technique [0002] Most of the traditional door frame casings are made of solid wood. In recent years, with the rapid development of the wood-plastic industry, the door frame casing profiles made of wood plastics have been widely used. In order to save material consumption, most of them adopt hollow structures. The structure of the wood-plastic door frame wire profile has the following defects: 1. The round hole deformation in the core of the wood-plastic door frame wire is relatively serious, which affects the strength and stiffness; 2. Due to the poor heat dissipation effect of the mandrel, the wood-plastic door frame More air bubbles are easily formed on the inner surface of the round hole of the sleeve core, thereby affecting the quality of the product; 3, the appearance of the product is not very attr...
