Dual-layer washing machine drainage pipe and extruder handpiece of washing machine drainage pipe

Abstract

The invention relates to a dual-layer washing machine drainage pipe and an extruder handpiece of a washing machine drainage pipe. The drainage pipe comprises an outer drainage pipe layer and an innerdrainage pipe layer. The outer drainage pipe layer sleeves the exterior of the inner drainage pipe layer and fixedly fits the inner drainage pipe layer, a handpiece assembly for producing the dual-layer drainage pipe comprises a bush die, an outer die assembly, a core die assembly and a flow divider, and the core die assembly comprises a core die, a core die base and a flow division shuttle whichare connected in sequence. The flow divider is arranged in the outer die assembly, a first fusion channel is formed between the flow divider and the outer die assembly, the core die base and the flowdivision shuttle are arranged in the flow divider, a second fusion channel is formed between the core die base and the flow division shuttle, the core die is arranged in the bush die, an extrusion channel is formed between the core die and the die bush, one end of the first fusion channel and one end of the second fusion channel join and communicate with one end of the extrusion channel, materialsgenerated after the first fusion channel and the second fusion channel join with each other are extruded out of the extrusion channel to form a blank of a dual-layer structure, and accordingly the drainage pipe made from the blank is of a dual-layer structure.

Description

technical field [0001] The invention belongs to the technical field of washing machine drain pipes, in particular to a double-layer drain pipe and an extruder head for producing the double-layer drain pipe. Background technique [0002] In daily life, the waste water of the washing machine needs to be discharged through the drain pipe of the washing machine. The existing drain pipes of the washing machine are divided into telescopic pipes or corrugated pipes that cannot be stretched. Need to be replaced periodically. [0003] In the prior art, the washing machine drain pipe is produced through a special extruder. The head of the extruder produces the blank, and then blows the blank to form a pipe, and finally stretches the finished product to form a telescopic tube. Pipes or corrugated finished products form corrugated pipes; however, the existing drainage pipe extruder head can only extrude a single-layer blank, and only single-layer structure drainage pipes can be produce...

[0003] In the prior art, the washing machine drain pipe is produced through a special extruder. The head of the extruder produces the blank, and then blows the blank to form a pipe, and finally stretches the finished product to form a telescopic tube. pipe or corrugated finished products to form corrugated pipes; however, the existing drainage pipe extruder head can only extrude a single-layer blank, and only single-layer structure drainage pipes can be produced through the single-layer blank.
