Abstract

The utility model discloses a mould head of a tubular product extrusion machine, which comprises a casing and a mould core arranged inside the casing. A mould cavity is formed between the inner wall of the casing and the outer wall of the mould core. One end of the casing is provided with an inlet of the mould cavity and the other end is provided with an outlet of the mould cavity. A filter mesh is arranged between the inner wall of the casing and the outer wall of the mould core. The mould head of the tubular product extrusion machine filters away grain impurities existing in melting materials through the filter mesh arranged in the mould cavity so as to guarantee the quality of tubular products.

Description

A kind of die head of pipe extruder

Technical field

The utility model relates to a kind of parts of plastic pipe extruder, relates in particular to a kind of extruder die head.

Background technology

Extruder has been applied in the processing of plastic pipe widely, the extruder discharge end is provided with die head, die head is made of housing and the core rod that is positioned at housing, between the outer wall of the inwall of housing and core rod, form die cavity, housing one end has the inlet of die cavity, the other end is the outlet (being the extruding end of tubing) of die cavity, and the raw material of fusion enters die cavity from the inlet of die cavity and finally extrudes from the outlet of die cavity through the reallocation back, obtains plastic pipe through cooling.

In the raw material of fusion, there is granule foreign, influences the microstructure and the mechanical property of tubing through regular meeting, therefore must be in the tubing extrusion molding with the granule foreign filtering, to guarantee and to improve the quality of tubing.

The utility model content

The utility model provides a kind of die head of pipe extruder, and the granule foreign that exists in can the filtering fused raw material guarantees the quality of tubing.

A kind of die head of pipe extruder, be made of housing and the core rod that is positioned at housing, form die cavity between the outer wall of the inwall of housing and core rod, housing one end has the inlet of die cavity, the other end is the outlet of die cavity, is provided with filter screen between the outer wall of the inwall of described housing and core rod.

As preferably, described filter screen is a tubular, the axis of filter screen and the dead in line of die head.

The granule foreign of the die head of the utility model pipe extruder by existing in the filter screen filtering fused raw material in the die cavity, the quality of assurance tubing.

Description of drawings

Fig. 1 is the internal structure schematic diagram of the die head of the utility model pipe extruder.

The specific embodiment

Referring to accompanying drawing, the die head of a kind of pipe extruder of the utility model, constitute by housing 1 and the core rod 2 that is positioned at housing 1, between the outer wall of the inwall of housing 1 and core rod 2, form die cavity, housing 1 one ends have the inlet 3 of die cavity, the other end is the outlet 4 of die cavity, is provided with filter screen 5 between the outer wall of the inwall of housing 1 and core rod 2.

Filter screen 5 is a tubular, the edge of filter screen 5 one ends and the inwall of housing 1 are fixed, the outer wall of the edge of the other end and core rod 2 is fixed, the axis of filter screen 5 and the dead in line of die head, promptly be in die head axis position, the raw material of fusion enters die cavity from the inlet 3 of die cavity during use, finally extrudes from the outlet 4 of die cavity through after the filtration of filter screen 5 at the die cavity middle part, obtains plastic pipe through cooling.

Claims

1. the die head of a pipe extruder, constitute by housing and the core rod that is positioned at housing, between the outer wall of the inwall of housing and core rod, form die cavity, housing one end has the inlet of die cavity, the other end is the outlet of die cavity, it is characterized in that, between the outer wall of the inwall of described housing and core rod, be provided with filter screen.

2. the die head of pipe extruder as claimed in claim 1 is characterized in that, described filter screen is a tubular, the axis of filter screen and the dead in line of die head.
