Abstract

Foamed synthetic resin wood having uniformed-foam in the inside of wood and natural-pattern on the outside was prepd. by again extruding of prefoamed wood for maximum foaming. The extruding molder consisted of transforting space(2) which was heated wood by heating oil at 100-200≰C, inlet(3) and outlet(4); of heating oil and sealing plate(6).

Description

Heating Molding Machine of Foamed Artificial Wood

1 is an exploded perspective view of the present invention.

Figure 2 is a perspective view of the snow installation condition of the present invention.

Figure 3 is an explanatory view of the molding process of artificial wood molded by the present invention.

4 is a partial perspective view of the foamed artificial wood finished through the heating molding machine of the present invention.

In the present invention, when the artificial wood is manufactured by using a foamed synthetic resin, the inner surface thereof is uniformly foamed, and the outer surface is foamed once again to maximize the appearance of the core material (artificial wood) that has been extruded and foamed so as to have a shape like a natural pattern. The present invention relates to a heating molding machine capable of producing artificial wood having an accurate cross section by preliminarily forming a mold at the same time as the zoom.

Conventionally, artificial wood extruded using only synthetic resin has a difficult cross-section and lack of pattern (appearance) and properties such as natural wood, and it is difficult to nail nails and screws. Also, Japanese Unexamined Patent Publication No. 50-123777 Although the art of manufacturing artificial wood using synthetic resin added with a blowing agent was disclosed as in 85657, in the technical method as described in Japanese Patent Application Laid-open No. 50-86567, the core material once extruded and foamed was Due to the re-defoaming with the heating type molding machine equipped with this, sharply angled artificial trees cannot be manufactured as in the present application, and the increase in production cost, difficulty in operation and operation, and the re-foaming of all parts are not possible. It is lacking in point and simplicity, and is extruded and foamed in a die in the same manner as in Japanese Unexamined Patent Publication No. 50-123777. The technology is disclosed, but there is no heating molding machine for foaming at an arbitrary magnification by the operation of the extruder as in the present invention, and also for re-foaming the extruded core material (artificial wood). When the core material is discharged from the extruder to the outside, the surface of the core material is re-foamed to the maximum where the incomplete foaming due to the partial hardening is caused by natural cooling, and effectively forms the natural pattern on the final product. It was difficult to preform into the desired shape.

Therefore, the present invention will be described in detail with reference to FIGS. 1 to 2 as a proposal to overcome this drawback as follows.

That is, the artificial wood distribution hole (2) in the center and the outer periphery of the main body (1) of the high temperature oil injection pipe (3) and the oil outlet pipe (4) formed the oil flow passage (5) in communication with each other The sealing plate 6 was screwed and assembled on the back side.

Detailed Description of the Invention According to the accompanying drawings of the present invention with reference to FIG. 3, when the extrusion resin-containing synthetic resin is expanded and foamed at a predetermined foaming ratio only from a conventional extruder, the interior of the artificial tree is completely foamed, but the surface is extruder. As the part is hardened by natural cooling as it is extruded from the furnace, oil having a high temperature of 100-200 ° C. or higher through an oil pump (not shown) in order to re-establish it again to the maximum. (Iii) Circulation to adjust the die temperature to 100-200 ℃ and introduce the extruded foam core (artificial wood) into the heated die to foam as much as possible and at the same time preliminarily shape the mold to produce As a conventional sizing die, it is molded into a final product shape and then quenched in a cooling water bath, taken out and cut to prepare a product.

The present invention is a heating molding machine that conducts heat of oil heated to about 100-200 ° C, and heat molding machine to re-foam artificial wood having a slightly hardened surface and to preform a mold at the same time. As the configuration is simple and according to the change of the shape of the artificial wood distribution hole (2) there is an advantage that can produce a variety of forms of various foaming magnification products with a small minimum installation cost.

Claims (1)

Drill the artificial wood distribution hole (2) in the center as described above and shown in the figure, and the oil inflow passage (5) in which the high temperature oil inflow pipe (3) and the oil outflow pipe (4) communicate with each other at the outer periphery thereof. A heat molding machine for a foamable artificial wood, wherein the sealing plate 6 is screwed and assembled on the back surface of the main body 1 on which the upper surface is formed.
