This a cooling device for extruding aircraft nose, direct action is in the aircraft nose discharge gate, cools down to extruding the material, more is favorable to the shaping, and convenient subsequent vacuum cooling shaping guarantees the shaping rate of work piece, when reducing the waste material and producing, reduces because the work piece not the economic loss that the shaping leads to.

Description

Cooling device for extruder head

Technical Field

The utility model relates to the technical field of extrusion molding, in particular to a cooling device for an extruder head.

Background

The head of the extruder is one of the more important parts in extrusion molding, wherein the head is generally fixed on the machine body by bolts, and materials are extruded out of the head by extrusion of an extrusion device and then enter a vacuum cooling device for cooling molding.

At present, in the mode, extruded materials are temporarily exposed to air between the machine head and the vacuum cooling equipment and then enter the vacuum cooling equipment, so that in actual production, the situation that the materials extruded by the machine head cannot enter the vacuum cooling equipment due to uncooled forming is easy to occur, and certain loss is caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a cooling device for an extruder head, which solves the problem that materials extruded by the extruder head cannot enter vacuum cooling equipment because the materials are not cooled and molded.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a cooling device for extruding aircraft nose, includes the cooling ring, the cooling ring links to each other with aircraft nose discharge gate screw thread, the clamp has the thermal insulating pad between cooling ring and the aircraft nose, the cooling ring is installed and is used for the circulation subassembly of cooling.

Preferably, the circulation assembly comprises a water inlet connector and a water outlet connector, the water inlet connector is communicated with the bottom of the cooling ring, and the water outlet connector is communicated with the top of the cooling ring.

Preferably, the thermal insulation pad is made of polytetrafluoroethylene.

Compared with the prior art, the utility model has the beneficial effects that: this a cooling device for extruding aircraft nose, direct action is in the aircraft nose discharge gate, cools down to extruding the material, more is favorable to the shaping, conveniently gets into subsequent vacuum cooling equipment, guarantees the shaping rate of work piece, when reducing the waste material and producing, reduces because the economic loss that the work piece is not the shaping and leads to.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In an embodiment, referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a cooling device for extruding aircraft nose, includes cooling ring 1, and cooling ring 1 links to each other with aircraft nose discharge gate screw thread, and the clamp has thermal-insulated pad 2 between cooling ring 1 and the aircraft nose, and cooling ring 1 installs the circulation subassembly that is used for the cooling.

It should be noted here that in the existing extrusion molding apparatus, the material extruded from the extruder head is exposed to the air for a certain distance, and then enters the vacuum cooling apparatus, in the technical solution described in this document, the cooling ring 1 is located at the section where the extruded material is exposed to the air, and a gap is left between the cooling ring 1 and the vacuum cooling apparatus, and the use of the cooling ring 1 can cool the material extruded from the extruder head more quickly, and is more beneficial to entering the vacuum cooling apparatus.

It can be understood that, through the cooperation cooling ring 1 that sets up of circulation subassembly, can be after extruding the aircraft nose ejection of compact, the very first time is cooled down the material, is favorable to the work piece shaping, conveniently gets into vacuum cooling equipment, wherein separates the design aim at of warm pad 2, to playing the effect that separates the temperature between cooling ring 1 and the aircraft nose, avoids under the effect of cooling ring 1, extrudes the material and leads to unable extrusion in the inside cooling of aircraft nose in advance.

Specifically, the circulating assembly comprises a water inlet connector 4 and a water outlet connector 3, the water inlet connector 4 is communicated with the bottom of the cooling ring 1, and the water outlet connector 3 is communicated with the top of the cooling ring 1.

The water inlet connector 4 and the water outlet connector 3 can be connected with an external cold water circulating system, so that the temperature of the cooling ring 1 is ensured to be lower.

It is understood that the water inlet joint 4 and the water outlet joint 3 in this embodiment are not limited to water cooling, and the cooling ring 1 may be cooled by a refrigerant, and the like, without departing from the principle and spirit of the present invention, and all of them fall within the protection scope of the present invention.

Further, the thermal insulation pad 2 is made of polytetrafluoroethylene.

It can be understood that the heat insulation pad 2 made of polytetrafluoroethylene has better heat insulation effect, and the temperature of the machine head is prevented from being reduced due to the cooling ring 1.

In the description of the present invention, it is to be understood that the terms "coaxial", "bottom", "one end", "top", "middle", "other end", "upper", "one side", "top", "inner", "front", "center", "both ends", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "disposed," "connected," "secured," "screwed" and the like are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; the terms may be directly connected or indirectly connected through an intermediate, and may be communication between two elements or interaction relationship between two elements, unless otherwise specifically limited, and the specific meaning of the terms in the present invention will be understood by those skilled in the art according to specific situations.
