Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mold for forming a reinforced resin tubular body that is capable of forming reinforced resin tubular bodies of a plurality of shapes or sizes.

Conventionally, when molding a reinforced resin tubular body, for example,
8-100463, a stepped cylinder consisting of two large-diameter cylindrical parts and a small-diameter cylindrical part with the same outer diameter of the large-diameter cylindrical part is formed with an end face of one small-diameter cylindrical part and an end face of the other large-diameter cylindrical part. They are concentrically and separably joined to form a joint molding mold, and a plurality of the joint molding molds are divisibly joined together at the end face of the small diameter cylindrical part directly or via an intervening mold. Also, using a mold made of
As in Japanese Patent No. 123464, a cored metal assembled by detachably connecting at least two mold members is sometimes used.

However, the above-mentioned cases are difficult to mold because there is no way to mold reinforced resin tubular bodies of multiple shapes or sizes with a single core mold. This method had the drawback that each core mold had to be prepared, which required a large amount of expense.

The present invention was developed with the aim of solving the conventional drawbacks as described above, and its gist is that the mold body is attachable to the shaft via the first connecting member, and The present invention relates to a mold for forming a reinforced resin tubular body in which a mold body can be attached to a shaft via a second connecting member instead of the first connecting member.

Hereinafter, the present invention will be explained with reference to embodiments of the drawings.

FIG. 1 is a sectional view showing one aspect of an embodiment of the present invention.

Reference numeral 1 designates a mold body, which projects inwardly and outwardly from one end of a pair of annular members 11 and 11, each having an outer diameter that is approximately the same as the inner diameter of the central portion of the reinforced resin tubular body with a socket to be molded. An annular flange portion 111, 111 is provided, an uneven portion is provided on the end surface of the other end, and one end of a short annular member 112, 112 having an uneven portion on the end surface is connected to the short annular member 112, 112. The other ends can come into contact with each other.

Reference numerals 2 and 2 designate socket molding parts, each having a flange part 211.211 at one end of a cylindrical member 21.21, which can be fixed at a predetermined position on the outer periphery of the mold body 1 with a long bolt.

Reference numeral 3 denotes a shaft, and male tapered portions are provided on the outer circumferential surface of both ends.

4.4 is a first connecting member in which a flange portion is provided on the outside of the short tube in a direction perpendicular to the axial direction thereof.

The socket molding parts 2, 2 are fixed at predetermined positions on the annular member 11.11 of the mold body 1, and the mold body 1 is fixed to the shaft core 3 via the first connecting member 4.4, and the socket mold bone is fixed. A joint mold is formed.

FIG. 2 is a sectional view showing another aspect of the embodiment of the present invention.

Reference numerals 4' and 4' designate second connecting members in which flange portions are provided on the outside of the short tube in a direction slightly inclined from the direction perpendicular to the axial direction of the short tube.

A second connecting member 4 instead of the first connecting members 4, 4 described above.
', 4' to connect the mold body 1 to the second connecting members 4', 4.
is fixed to the shaft core 3 via ', thereby forming an elbow type pipe joint molding die.

As mentioned above, in the reinforced resin tubular body mold of the present invention, the mold body can be attached via the first connecting member, and the mold body can be attached via the second connecting member instead of the first connecting member. Since it can be attached to the shaft, it is possible to mold reinforced resin tubular bodies such as pipe joints or tubes of a plurality of shapes and sizes.
