Embodiment Construction

[0015] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0016]

[0017] figure 1 Middle (a) is a front view showing the structure of the blow molded product manufacturing apparatus according to the embodiment of the present invention, figure 1 Middle (b) is a front view showing when the built-in component is installed in the manufacturing device. However, when the concave forming molds 17a and 17b are shown, the concave portions of the concave forming molds 17a and 17b are shown in cross-sections. Described later figure 2 with image 3 The same is true in Chinese.

[0018] figure 1 The manufacturing apparatus 10 shown in (a) is used to form an automobile fuel tank as a blow-molded product. The manufacturing device 10 has two outer rail parts 11, 12, two mobile stations 14a, 14b, and two mobile stations 15a, 15b. Among them, the two outer rail parts 11, 12 are arranged in parallel with the rail faces facing each other. The rail...

Abstract

When blow molded products are produced by the blow molded product manufacturing device (10), a pair of forming dies (17a, 18a) and another pair of forming dies (18b, 17b) arranged across a sheet-shaped parison (P) are used to manufacture blow molded products. ), forming the sheet-shaped parison (P) into a predetermined shape. Next, the built-in parts (20a, 20b) are fixed on the formed sheet-shaped parison (P) by the piston portion (19), and then the cutting tool (25) is used to cut the sheet-shaped parison (P) using a pair of Cutting is performed between the formed part formed by the forming dies (17a, 18a) and the formed part formed by the other pair of forming dies (18b, 17b). After the cutting is completed, predetermined molding dies (17a, 17b) are made to face each other, and both are clamped. Thus, the formed two sheet-like parisons (P1, P2) are tightly joined together to form a blow molded product (P3).

Description

Technical field [0001] The present invention relates to a manufacturing device and a manufacturing method of blow-molded products such as fuel tanks mounted on automobiles. Background technique [0002] A blow-molded automobile fuel tank is provided with components related to valves and pumps, components that ensure the strength of the fuel tank, components that suppress fuel fluctuations, and various accessory components of the fuel tank. In the case of installing these built-in components on the inner wall of the fuel tank, considering the time required for the installation operation, etc., it is preferable to install the built-in components on the fuel tank after the manufacturing is completed. The built-in components are installed during the manufacturing process. [0003] As a prior art for mounting built-in components in the manufacturing process of a fuel tank, for example, Patent Document 1 describes a manufacturing device. Using this manufacturing apparatus, a fuel tank ...
