Device for blow-molding automobile oil tank and automatically stretching material and feeding embedded piece

Abstract

The invention discloses a device for blow-molding an automobile oil tank and automatically stretching and feeding an embedded piece. The device comprises a material stretching mechanism (1), an expanding mechanism (2) and a feeding mechanism (3). According to the invention, by using an automatic auxiliary device consisting of the material stretching mechanism, the expanding mechanism and the feeding mechanism, a technical scheme of automatically blow-molding the automobile oil tank is realized in coordination with a mold so as to overcome problems and defects of low efficiency, large labor intensity, high cost and high reject rate in the prior art. By using the device for blow-molding the automobile oil tank and automatically stretching and feeding the embedded piece, disclosed by the invention, purposes of enhancing the efficiency, reducing the labor intensity, reducing the cost and increasing the standard rate of the products are realized in the blow molding production of the automobile oil tank through automatically stretching the material and feeding the dash board embedded piece.

Description

technical field [0001] The invention relates to a process auxiliary device for blow molding products, specifically refers to a blow molding plastic automotive fuel tank product, which is used to automatically stretch the blank and transport the insert into the blank. Device for automatic stretch delivery inserts for tanks. Background technique [0002] Blow-molded multi-layer automotive fuel tank products are a method of blowing hot-melt plastic blanks closed in a mold to form multi-layer hollow plastic products by means of gas pressure. Different from ordinary plastic fuel tanks, in order to suppress the violent surge of fuel in the fuel tank with the bumps of the driving car, the interior of the plastic car fuel tank needs to be equipped with anti-wave boards to reduce the noise generated by the car during driving and reduce potential safety hazards; In the process of forming an automobile fuel tank, the anti-wave plate is embedded in the blank as an insert when blow mold...

Problems solved by technology

Different from ordinary plastic fuel tanks, in order to suppress the violent surge of fuel in the fuel tank with the bumps of the driving car, the interior of the plastic car fuel tank needs to be equipped with anti-wave boards to reduce the noise generated by the car during driving and reduce potential safety hazards; In the process of forming an automobile fuel tank, the anti-wave plate is embedded in the blank as an insert when blow molding the automobile fuel tank, and is fixedly embedded in the automobile fuel tank as the blank is formed in the mold; the prior art blow molding automobile In the oil tank, the extruder extrudes the semi-molten cylindrical plastic blank, first stretches the cylindrical blank manually with a stretching rod, and then manually inserts the anti-wave plate into the blank with the help of tools, after that, the mold is closed Mold blow molding, forming; manual stretching to deliver the anti-wave board has low efficiency, high work intensity, and high labor cost, and the manual delivery of the anti-wave board is prone to lodging and defective products. In addition, if the stretching material is not delivered in time Due to the cooling of the blank material, the cold material has to be cut off, resulting in waste. Therefore, the existing technology has the problems and deficiencies of low efficiency, high work intensity, high cost, and high rate of defective products.
