Description

technical field [0001] The invention relates to a fuel tank mold insert installation mechanism for a blow mold. Background technique [0002] At present, there are two installation methods for the fuel filler insert, one is to punch a hole on the formed fuel tank, and then heat-weld the fuel filler insert to the hole; the other is to fix it by a clamping mechanism At the corresponding position of the mold cavity, after the fuel tank is blow-molded, the fuel filler insert is extruded from the blowing needle through the clamping mechanism from the outside to the inside, and then cooled and shaped. However, the former not only has high labor intensity and low efficiency, but also perforates the microstructure between the polymer materials of the fuel tank, making the mechanical properties of the openings worse, and is prone to deformation during hot-melt welding. situation, precision and airtightness are poor, resulting in low yield and high cost; but the latter, the prior art...
