Description

Technical Field

[0001] The utility model relates to a heat preservation device for a two-piece blow molding process parison. Background Art

[0002] A high-pressure fuel tank refers to a fuel tank whose internal pressure is close to the atmospheric pressure. There is a discharge valve inside the high-pressure fuel tank, which opens when the internal pressure of the fuel tank is too high to discharge excess gasoline vapor into the atmosphere to ensure the safety of the inside of the fuel tank.

[0003] With the development trend of new energy, the application of high-pressure fuel tanks is becoming more and more frequent. High-pressure fuel tanks need to adopt a two-piece blow molding process, that is, the original traditional barrel-shaped blank is changed to a two-piece type. Since the mouth core mold of the blow molding equipment requires a certain amount of time in the process of material discharge, the temperature of the blank of the two-piece high-pressure fuel tank needs to be guaranteed during production. Otherwise, the structural strength of the mold line when the upper and lower molds of the high-pressure fuel tank are closed is insufficient. When the ambient temperature is low, the fuel tank is prone to leakage due to the low temperature of the blank. Utility Model Content

[0022] In this technical solution, the mounting seat is fixed by mounting bolts to ensure that the mounting frame is fixed and stable. By starting the cylinder, the cylinder pushes the fixed installed adjustment seat to move, which makes it convenient to adjust the position of the adjustment seat, and to adjust the position of the insulation part through the adjustment seat, so as to keep the extruded billet warm.
