An ecological wood foam extrusion die with a return-shaped core

Abstract

The invention provides an ecological wood foam-extrusion die having a homocentric-square-shaped core body. The foam-extrusion die includes a water jacket, a bush die I, a bush die II, a die body and a core rod, wherein the water jacket, the bush die I, the bush die II and the die body are successively and fixedly connected to each other. The core rod is clamp-mounted in the die body, the bush die I and the bush die II and is homocentric-square-shaped. The homocentric-square-shaped core rod is composed of an inner channel and an outer channel, wherein the outer channel sleeves the inner channel and the length of the inner channel is larger than that of the outer channel. The inner channel is stretched to the connection surface of the bush die I to the water jacket in the extrusion direction of the die. A plurality of large division holes are uniformly distributed annularly in the outer channel and a plurality of small division holes are uniformly distributed annularly in the inner channel, wherein each large division hole is arranged individually with the corresponding small division hole. The foam-extrusion die is simple and reasonable in structure. A product manufactured through the die not only has the texture of solid wood but also has the annual ring wood grain, is high in compactness and good in secondary processing performance. The die is mainly used for manufacturing an ecological wood product.

Description

technical field [0001] The invention relates to the technical field of ecological wood production equipment, in particular to an ecological wood foaming extrusion die with a return-shaped core. Background technique [0002] At present, the production and manufacture of ecological wood products on the market are mainly produced by foaming ecological wood extrusion molds. This kind of mold generally uses wood-plastic cores, but the products produced cannot see the imitation annual ring wood grain, and the product density Poor, secondary processing performance is relatively poor. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems existing in the foaming ecological wood extrusion dies on the market, and to provide an ecological wood foaming extrusion die with a return-shaped core with a simple and reasonable structure, beautiful products and high compactness. . [0004] The specific scheme of the present invention...
