Structure and method for clamping built-in component in hollow container

Abstract

The present invention provides a structure for clamping a built-in component (7A,7B,8) in a hollow container, the container being formed by clamp molding using a pair of a first mold piece (F) and a second mold piece (F), the first mold piece being for forming a first half of the container (Tc), the second mold piece being for forming a second half of the container (Tb), the structure comprising: a first support member secured (1A,1B) to an inner wall surface of the first half of the container (Tc) and having a first connection portion and a first clamp portion; a second support member (2A,2B) secured to an inner wall surface of the second half of the container (Tb) having a second connection portion and a second clamp portion, wherein the built-in component (7A,7B,8) is clamped between the first support member (1A,1B) and the second support member (2A,2B) with the first connection portion and the second connection portion coupled to each other.

Description

technical field [0001] The present invention relates to a clamping structure and a clamping method of a built-in component in a resin hollow container such as a fuel tank mounted in an automobile. Background technique [0002] The fuel tank of a car contains various parts that come with the fuel tank, such as valves, pumps, and pipes. When installing these built-in parts in the tank main body, in consideration of the complexity of the assembly work, it is preferable to adopt the method of using the manufacturing process of the tank main body as compared with the method of subsequently adding to the completed fuel tank main body. , to be installed in this process. [0003] As a conventional example of the latter mounting method, the method described in patent document 1 is mentioned. This document describes a technique in which a pair of holding members are mounted on a parison (separated shell) replicated (transferred, adhered) to an outer mold via a pneumatic cylinder, an...

AI Technical Summary

Problems solved by technology

[0006] According to the technology of Patent Document 1, when the pipelines communicate normally, it can be considered that the pipelines are stably fixed to the main body of the fuel tank through a pair of holding members, but if the pipelines are axially misaligned during the connection, then The connector plug parts may collide with each other and cause the pipeline to fall off from the holding part and not connect
