A hollow blow molding plastic fuel tank in-mold processing device

Abstract

The invention discloses an in-mold processing device for a hollow blow-molded plastic oil tank, which comprises a blow mold, a device frame, a power mechanism, a transmission mechanism, a fuel filler processing mechanism, and an oil mark nozzle processing mechanism; the fuel filler processing mechanism includes a first bearing seat , the first processing shaft, the second driven gear and the first cutter assembly; the oil mark port processing mechanism includes the second bearing seat, the second processing shaft, the third driven gear, the second cutter assembly, the second pulling rod and Second cylinder. In the present invention, by integrating the oil filler processing mechanism and the oil gauge hole processing mechanism in the blow molding mold, the fuel filler and the oil gauge hole can be processed at one time after the blow molding is completed, which simplifies the production process and improves the production efficiency; The processing mechanism and the oil level port processing mechanism are respectively equipped with a first pull rod and a second pull rod to prevent the waste from the cut filler port and oil mark port from entering the inner cavity of the plastic fuel tank, reducing the processing waste cleaning process of the plastic fuel tank, Realized chipless machining.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to an in-mold processing device for hollow blow molding plastic fuel tanks. Background technique [0002] In the blow molding process of the existing hollow blow molding plastic fuel tank, the technology of molding first and then processing is adopted, that is, after the fuel tank is formed, the product is taken out from the mold, and then moved to another mechanical processing equipment, such as a vertical drilling and milling machine , bench drills, etc., use special tooling to clamp the product, and then use special drilling tools, such as twist drills, or special design milling cutters, to drill or mill holes for product fuel ports and oil mark holes; the main The existing problems are: 1) prolonging the production process of the entire product and increasing the cost of the product; 2) debris generated during the hole machining process will remain inside the product ...

Problems solved by technology

[0002] In the blow molding process of the existing hollow blow molding plastic fuel tank, the technology of molding first and then processing is adopted, that is, after the fuel tank is formed, the product is taken out from the mold, and then moved to another mechanical processing equipment, such as a vertical drilling and milling machine , bench drills, etc., use special tooling to clamp the product, and then use special drilling tools, such as twist drills, or special design milling cutters, to drill or mill holes for product fuel ports and oil mark holes; the main The existing problems are: 1) prolonging the production process of the entire product and increasing the cost of the product; 2) debris generated during the hole machining process will remain inside the product and need to be cleaned with a special chip removal tool, and During the customer's use, the oil passage blockage often occurs

[0003] In order to solve such problems, the manufacturer mainly adopts the following methods: 1) Increase the air blowing pressure when cleaning the inside of the fuel tank to prolong the cleaning time; 2) After the fuel tank is cleaned, the customer requires the manufacturer to perform another cleaning inspection with gasoline This process increases the uncontrollable unknown risks in the production process, and is unanimously resisted by manufacturers
