Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a formwork for manufacturing a pseudo-wooden pole having a wood pattern formed on its surface, and a method for manufacturing the same.

"Prior Art and Problems to be Solved by the Invention" Conventionally, the formwork for manufacturing pseudo-wooden poles by centrifugal compaction molding involves attaching a ready-made rubber pseudo-wooden pattern sheet b to the inner surface of a two-split formwork a using double-sided adhesive tape or It is manufactured by directly bonding using an adhesive or the like.

However, in such conventional manufacturing methods, it is difficult to adhere the pseudo-wood pattern sheet b to the entire inner surface of the formwork a, so a large pseudo-wood pattern sheet is cut and divided into parts for the upper and lower formworks. Then, the upper and lower sheets are further cut and divided into multiple sheets, and these divided sheets b are continuously glued in the longitudinal direction of each formwork a, so that each divided sheet b
It is difficult to match the pattern at the seams of
The pattern at the seam had to be manually corrected each time, and this work was extremely troublesome.

In addition, molded products have problems such as unevenness and burrs at the joints, resulting in poor finished appearance.
Furthermore, since the pseudo-wood pattern sheet does not have sufficient adhesive strength to the formwork, there are problems in that it peels off each time it is molded and needs to be replaced for each product.

"Means for Solving the Problems" In order to solve the above-mentioned conventional problems, the present invention has the following features:
A perforated plate is attached to the inner surface of the form, and a pseudo-wood master with a pseudo-wood pattern formed on the surface thereof is fitted into the form so as to create a gap between it and the inner surface of the form. By injecting and filling a hardening material such as resin and removing the fake wood master from the mold after curing, a seamless and strong rubber fake wood pattern layer is formed by casting a perforated plate over the entire inner surface of the mold. , thereby making it possible to obtain a pseudo-wood pole with a good finish and appearance, as well as a formwork for producing a pseudo-wood pole that can be used for a long period of time without having to be reattached every time the product is removed from the mold. This paper proposes a manufacturing method for the same.

``Example'' Below, an example of the present invention shown in the drawings will be described. The inner surface of the upper and lower half-split formwork 1 for centrifugally compacting a pseudo-wood pole is made of punching metal,
A perforated plate 2 such as a wire mesh is attached by a fixing material 3 such as screws or bolts or by welding, and the perforated plate 2
A pseudo-wood pattern layer 4 made of a hardened material such as rubber or synthetic resin is integrally formed by casting the material.

Next, the forming process of this pseudo-wood pattern layer 4 will be explained.

First, as shown in Fig. 3, the inner surfaces of the upper and lower formworks 1 are coated with adhesive, and then the perforated plate 2 is attached.In this state, the formwork 1 is turned over as shown in Fig. 4, and the inside Fake wood master 5 with a faux wood pattern formed on the surface
are fitted to the inner surface of the formwork 1 while maintaining a required gap, and the area around the gap is sealed.

Then, a hardening material such as liquid rubber or liquid synthetic resin is injected and filled into the gap on the inner surface of the form 1 through an injection port 6 using a scaffolding bolt hole provided in the form 1 and cured.

After the hardening material has hardened, the pseudo-wood master 5 is removed from the mold, and the pseudo-wood pattern layer 4 with the pseudo-wood pattern transferred to its surface is molded by casting around the perforated plate 2 and firmly adhering to the inner surface of the formwork 1. .

"Effects of the Invention" As described above, according to the present invention, a perforated plate is attached to the inner surface of the form, and a pseudo wood master having a pseudo wood pattern formed on the surface is placed inside the form so as to create a gap between it and the inner surface of the form. Once fitted, a hardening material such as liquid rubber or liquid synthetic resin is injected and filled into the gap, and after hardening, the fake wood master is removed from the mold, and a perforated plate is cast over the entire inner surface of the form and bonded together. By forming a strong pseudo-wood pattern layer with no seams, it is possible to obtain a pseudo-wood pole with a good finish. Since it is reinforced with a perforated plate, there is no need to reapply it each time the product is removed from the mold, so it can be used for a long time.
