Description

A kind of plastic fuel tank combination forming mechanism

Technical field

The utility model relates to a kind of plastic fuel tank combination forming mechanism, belongs to the plastic fuel tank technical field.

Background technology

Plastic fuel tank inside needs the installation function part, as washboard, liquid/vapor separator, liquid level sensor, oil pump etc.In order to realize being connected between the outer parts of part and casing in fuel tank, traditional method be fuel tank this body formed after, punching on tank wall, welding and assembling.The number of openings of minimizing on box body wall, the size that reduces perforate are conducive to reduce the interior fuel-steam of casing to the discharge capacity of environment, have increased difficulty for parts with being connected of casing but do also like this.

In order to realize the target of low emission, the assembly of welding on fuel tank and assembling is placed into the inside of fuel tank, be to reduce hydrocarbon to a feasible method of external leakage.Blowing tubular parison for traditional wants to realize that assembly is built-in, can only assembly be put into parison inside by the parison port, and the size of parison port is less, and large-sized assembly can't be put into wherein.For making built-in part have the free degree of increase, gradually two parison blow molding methods have been produced, two parisons flow between left and right half module, blow in the backward parison of left and right half module matched moulds to make the left and right parison be fitted in respectively on the die cavity wall of left half module, right half module and moulding.

Publication number is the Chinese invention patent of 102962942A, a kind of plastic fuel tank shaped device is disclosed, comprise base, the upper plane of base is equipped with cross slide way along its length, left clamping mechanism and the right clamping mechanism that can move along cross slide way respectively under hydraulic oil cylinder driving are installed on cross slide way, left half module is installed on left clamping mechanism, right half module is installed on right clamping mechanism, be respectively equipped with left and right die cavity on left and right half module, left and right die cavity is arranged in opposite directions and the left and right two halves shape size with fuel tank is identical respectively; Be provided with the longitudinal rail perpendicular with cross slide way between left and right half module, the longitudinal rail two ends are separately installed with preformed template and the built-in mechanism that guide rail longitudinally moves, the left and right end face of preformed template matches with the end face in opposite directions of left and right half module respectively, and on built-in mechanism, clamping has the built-in part of fuel tank.This device need not punching welding on fuel tank, has increased the intensity of fuel tank, has improved the sealing property of fuel tank; When being used for blowing, because parison moulding and required time of built-in part on left and right half module will be longer than the required time of preformed, when left and right half module is in running order, the preformed template often is in wait state, and parison will adapt with the working time of preformed template from the speed that die head flows out, and affects parison and has namely affected whole operating efficiency from the decrease speed of die head.
