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
The present invention relates to ecological wooden production equipment technical field, especially a kind of ecological wooden foam extrusion die tool taking back core body.
Background technology
At present, manufacture ecological wooden goods on the market, mainly produce with foaming ecological wooden extrusion die, this mould generally adopts wood to mould core body, but the goods produced cannot see imitative annual ring wood grain, and product packing is poor, and suitability for secondary processing is also poor.
Summary of the invention
Object of the present invention is exactly the problems referred to above existed for the ecological wooden extrusion die that foams in the market, provides a kind of simple and reasonable, makes the ecological wooden foam extrusion die tool taking back core body that product is attractive in appearance, packing is high.
Concrete scheme of the present invention is: a kind of ecological wooden foam extrusion die tool taking back core body, include water jacket, mouth mould I, mouth mould II, die body and plug, wherein water jacket, mouth mould I, mouth mould II, die body is fixedly connected sequentially together, plug is installed among die body and mouth mould I and mouth mould II, it is characterized in that: described plug is back-shaped plug, back-shaped plug is made up of inner ring duct and duct, outer ring, duct, outer ring is sleeved on inner ring duct, inner ring orifice throat length is greater than outer ring orifice throat length and inner ring duct is extruded direction along mould and extended to mouthful mould I and water jacket abutted surface place, duct, described outer ring pressed on ring shape is evenly distributed with some large shunt holes, described inner ring duct pressed on ring shape is evenly distributed with some little tap holes, each large shunt hole and little tap hole are mutually independent.
Back-shaped plug cross section described in the present invention can be set to circular or square two kinds.
Operation principle of the present invention: the melt making ecological wooden enters extrusion die from die body entrance, under the effect of extruding force, melt enters corresponding runner separately from the large shunt hole and little tap hole in duct, outer ring and inner ring duct, and press closely wherein, then carry out release foaming at water jacket stable section and outlet thereof, extrude wood plastic product; The present invention is simple and reasonable, and the product made not only has the wood grain of solid wood to have again annual ring wood grain, and product packing is high simultaneously, and suitability for secondary processing is good.
