Mold of integrated type fuel tank

Abstract

The invention provides a mold of an integrated type fuel tank. The mold comprises a first mold, the first mold comprises a first front mold and a first rear mold, the first front mold and the first rear mold can be jointed to form a first mold cavity, the first mold cavity is used for forming a shell with a liquid injection opening, the side, facing the first mold cavity, of the first front mold is provided with a sliding block used for forming an outer surface of the liquid injection opening, the sliding block is perpendicular to the mold opening direction when the first mold is opened and slides towards the outer side of the first front mold, the side, facing the first mold cavity, of the first rear mold is provided with a first insert used for forming an inner surface of the liquid injection opening, the first rear mold is provided with a power mechanism, a thread is mounted on the periphery of the first insert, and the first insert is driven by the power mechanism to rotate aroundthe self axis relative to the first rear mold and move relative to the first rear mold along the self axis. Through cooperation of the sliding block and the first insert, during mold opening, the liquid injection opening can be rapidly and efficiently separated out, and the whole efficiency of shell forming can be improved.

Description

technical field [0001] The disclosure belongs to the field of molds, and specifically provides a mold for an integrated fuel tank. Background technique [0002] Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. [0003] At present, with the rapid development of the automobile industry, the structural forms of automobile fuel tanks and urea tanks are also constantly changing. The integrated fuel tank integrates the fuel tank and the urea tank into one box, and is formed by injection molding and welding processes. In the injection molding pro...
