Double-layer flow guide material storage type die head device of blowing machine

Abstract

The invention relates to a double-layer flow guide material storage type die head device of a blowing machine, and belongs to the technical field of blowing machines. The double-layer flow guide material storage type die head device comprises a driving mechanism, a material storage barrel, a die sleeve mechanism, a material storage core, a bush die mechanism and a material pushing ejection rod fixing disc, wherein the material storage barrel is provided with a material storage barrel cavity, and a material storage barrel cover is arranged at the upper portion of the material storage barrel cavity; the die sleeve mechanism is connected with the material storage barrel; the material storage core and a material storage barrel fixed connection cover are fixed; the bush die mechanism is connected with a center pull rod and a bush die guide connecting mechanism at the same time; and the material pushing ejection rod fixing disc is arranged in the material storage barrel cavity. The double-layer flow guide material storage type die head device is characterized by further comprising a plastic melt double-layer flow guide mechanism arranged in the material storage barrel cavity; a pair of material guide pipes are inserted into the material storage barrel cover, the middle portion of each of the pair of material guide pipes is provided with a material guide pipe material guide groove, material leading pipes are arranged in material guide pipe cavities, and a plastic melt leading-in hole is formed in the side wall of the material storage barrel cover; and the material pushing ejection rod fixing disc is provided with material leading pipe fixing holes, and the lower ends of the material leading pipes and the material pushing ejection rod fixing disc are fixed. The structure of the material storage core is simplified; the quality of a hollow plastic container obtained after huffing molding is guaranteed; and the working efficiency of the blowing machine is improved.

Description

technical field [0001] The invention belongs to the technical field of blow molding machinery, and in particular relates to a double-layer diversion material storage type die head device of a blow molding machine. Background technique [0002] The blow molding machine is the equipment for processing hollow plastic containers, such as packaging barrels used for filling pharmaceutical and chemical raw materials, oil products, various additives, various solvents, additives and even hazardous chemicals. Since the blow molding mechanism of the blow molding machine belongs to the known technology, for example, please refer to the Chinese patents CN202062631U (three-layer plastic container molding machine), CN201941151U (plastic container automatic hollow molding machine) and CN202162995U (large blown plastic container automatic hollow molding machine) , etc., so the applicant no longer expands the description. [0003] The technical information about the storage type die head dev...

Problems solved by technology

But this CN104191594A still has the following shortcomings: First, because the plastic melt is divided into two and then divided into four, it is realized by the melt flow channel directly formed on the material storage core and the outer layer sleeve with strict processing technology requirements, Therefore, the formation of many melt flow channels on the lengthy material storage core and the outer sleeve will inevitably bring difficulty to manufacturing and the manufacturing cycle will be long and the cost will be high; ) to implement injection, but it does not give the technical enlightenment on how to ensure that the plastic melt is still leading the material into the storage barrel while injecting the material, because the blow molding machine can only work under the premise that the injection and the leading material are kept in parallel. Efficiency can be maximized
