ある。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to molding a hollow body in which a plurality of tubular parts communicating with the hollow body are provided around the hollow body in a direction in which the axes intersect with each other. This invention relates to a blow molding device for hollow bodies.

ればならない。Conventional technology Fig. 6 shows a lumbar support α for an automobile part which is an example of the above-mentioned hollow body.
, b, -... are provided protruding in directions orthogonal to each other within substantially the same plane. Since a pipe joint is inserted into the inner surface of each tubular portion of the ramper support α, the diameter of each tubular portion must be a smooth cylinder with precision.
従来この樵の中空体はブロー成形法にて成形されている
。Conventionally, the hollow body of this woodcutter has been molded by blow molding.

う、上記し九ように、この凹溝は管状部にパイプジヨイ
ントを挿入して中空部と連通し九場合に、空気漏れの原
因となる。Problems to be Solved by the Invention When a hollow body in which a tubular part communicating with the hollow part protrudes around the periphery is molded using a normal blow molding method, a concave groove peculiar to blow molding is formed on the inner circumferential surface of the pinch-off part of each tubular part. As mentioned above, when a pipe joint is inserted into the tubular part and communicates with the hollow part, this groove becomes a cause of air leakage.
この凹溝の発生を防止するには、管状部の円径を規制す

成形することが考えられるが、所謂パリスンによるプロ
ー成形では、パリスンをこの；アで突き破らなければな
らず不可能であった。In order to prevent the occurrence of this groove, it is possible to insert a core in advance to regulate the circular diameter of the tubular part and press it to form it when the mold is clamped. However, in blow molding using a so-called parison, It was impossible because we had to break through with this;a.

きないという問題があった。Therefore, a tiger molding method is used in which two sheets are used and the core is placed between the sheets to mold a tubular part with a regulated diameter. , unlike the molding method using Balison,
Since the pressure between the sheets is the same as atmospheric pressure, there is a problem that the sheets come into contact with each other and weld together when the base is tightened, making it impossible to form a hollow part.

A left and right split mold that has a cavity for the side part and a cavity for the tubular part that molds the tubular part, and a shape that surrounds this split mold and whose inner pressure corresponds to the cavity for the tubular part of the split mold above. an intermediate mold having a core for regulating the circular diameter of the molded product and positioned between the two split molds, and a frame-shaped frame surrounding each of the split molds;
It is provided with a spring bias toward the tip of the split mold so that it can be moved in the backward direction from approximately the same position as the tip of each split mold, and the intermediate mold is attached to the intermediate mold prior to the clamping of the split mold. and a sliding mold that comes into close contact with the end face of the intermediate mold, and at least 30,000 of the upper and lower, front and rear frame members that make up the intermediate mold.

金型を開いて成形品を増り出す。It has a structure that allows it to be divided and moved in the front and back direction, and two molten sheets are placed between the left and right divided molds and the intermediate mold, and then each molten sheet is used to clamp the divided molds. Prior to this, the sliding molds are used to airtightly clamp each end of the intermediate mold, and then the left and right split molds are moved forward and clamped to form a hollow body inside the intermediate mold. When the #I star shape is used, the frame member of the intermediate mold is divided and moved and removed from the molded product], and the divided mold is opened to increase the number of molded products.
