Horizontal type blow molding die for automobile oil tube and blow molding method thereof

Abstract

The invention discloses a horizontal type blow molding die for an automobile oil tube and a blow molding method thereof. The horizontal type blow molding die comprises an upper die (1) and a lower die (2). In the technical scheme, the blow molding method comprises the following steps of: manufacturing the blow molding die to form two coincidental dies which are arranged horizontally and correspond up and down; when the blow molding die operates, lifting the upper die, moving the lower die out horizontally to load tubular blanks; restoring the lower die restores, pressing the upper die to close the die, blowing air to the tubular blanks for bubbling, and maintaining pressure and cooling, so that the blanks are formed to form a hollow oil tube product; and opening the die, clamping the product to lift upwards by the upper die, moving the lower die out horizontally, and allowing the upper die to release the product, so that the product drops to demold. In the horizontal type blow moldingdie for the automobile oil tube, due to the adoption of the horizontal die, the tubular blanks are put into a curved cavity of the lower die conveniently according to the shape of the oil tube product, and are formed without generating flashes; and thus, the defects of treating the flashes by a vertical die are overcome, and the blow molding of the automobile oil tube fulfills the aims of improving quality, saving raw materials, reducing cost, saving energy and reducing energy consumption.

Description

technical field [0001] The invention relates to a blow molding mold, in particular to a horizontal blow molding mold for automobile oil pipes formed by horizontal blow molding and a blow molding method thereof. Background technique [0002] In the prior art, the blow molding of automobile tubing follows the method of vertical blow molding of plastic bottles. The vertical blow molding of plastic bottles is that the molten plastic extruded by the extruder is blown by the blowing die to make the diameter smaller than the diameter of the finished plastic bottle. The cylindrical bubble-shaped blank, the bubbles droop with the help of gravity, and are embedded in the cavity of the bottle shape in the second valve of the vertical device, which conforms to the mold. On the wall of the mold cavity, after cooling, the air bubbles are formed into hollow plastic bottles; the vertical blow molding of plastic bottles is to use gravity to make the air bubbles sag naturally, so that the air...

AI Technical Summary

Problems solved by technology

The flash cuts not only affect the appearance quality of the oil pipe, but also affect the mechanical strength and quality of the oil pipe structure due to the uneven thickness of the pipe wall at the cut. consumption, and the downgrading of recycled materials leads to serious loss of new materials and increases the cost of products; therefore, the existing technology has problems and deficiencies such as poor quality, hidden dangers of leakage accidents, high cost, high energy consumption, and serious waste of raw materials
