Problems solved by technology

[0002] The plastic extrusion mold is a mold used for plastic pipe forming. It is installed at the output end of the extruder. When producing plastic pipes, it is necessary to use a die formed by a combination of a die and a core die for extrusion. The die controls the external shape of the plastic pipe. , the mandrel controls the internal shape of the pipe. When the plastic is extruded, because the plastic pipe is not cooled immediately, and due to gravity, the plastic pipe is easily deformed in the radial direction when it is extruded, and even the wall thickness is uneven. Lead to poor structural performance of the whole tube

Abstract

The invention provides a novel cooling type plastic pipe mould which comprises an outer mould body, a core mould body and a cooling structure. The core mould body is fixed to the center of an inner cavity of the outer mould body, and a runner is formed. A through cooling pipeline is arranged on the solid portion of the core mould body. The external end of the cooling pipeline of the core mould body is connected with a support main body structure, and the free end of the support main body structure is connected with a support. The support main body structure is of a columnar structure with a hollow cooling pipeline. An outer mould cavity wall cooling channel is formed inside the solid portion of the outer mould body, one end of the outer mould cavity wall cooling channel is connected with a master cooling pipeline, and the other end of the outer mould cavity wall cooling channel is connected with an annular cooling channel of the outer mould body. The annular cooling channel of the outer mould body communicates with an external cooling part of the outer mould body, and the external cooling part of the outer mould body is fixed to the outer end of the outer mould body. The internal end of the cooling pipeline of the core mould body communicates with the master cooling pipe. The novel cooling type plastic pipe mould can support extruded flexible plastic pipes, uniformity of the wall thickness of the plastic pipes can be improved, and meanwhile, the cooling and solidifying speed of the plastic pipes is increased due to the fact that precooling is carried out inside and outside the pipes simultaneously.

Description

technical field [0001] The invention belongs to the technical field of plastic pipe extruders, and in particular relates to a die head capable of supporting and precooling the plastic pipe during extrusion. Background technique [0002] The plastic extrusion mold is a mold used for plastic pipe forming. It is installed at the output end of the extruder. When producing plastic pipes, it is necessary to use a die formed by a combination of a die and a core die for extrusion. The die controls the external shape of the plastic pipe. , the mandrel controls the internal shape of the pipe. When the plastic is extruded, because the plastic pipe is not cooled immediately, and due to gravity, the plastic pipe is easily deformed in the radial direction when it is extruded, and even the wall thickness is uneven. The structural performance of the whole pipe is poor. Contents of the invention [0003] In view of this, the present invention aims to propose a plastic extrusion die with a...
