Description
Technical Field
The utility model belongs to the technical field of the extrusion die sleeve technique and specifically relates to a plastic tubing is extrusion die sleeve for extruder is related to.
Background
The plastic extrusion die is used for forming a plastic pipe and is arranged at the output end of an extruding machine, when the plastic pipe is produced, the plastic pipe is extruded by adopting a die formed by combining a die and a core die, the external shape of the plastic pipe is controlled by the die, the internal shape of the pipe is controlled by the core die, after the plastic is extruded, the plastic pipe is not immediately cooled, and the plastic pipe is easily deformed in the radial direction and even has the problem of uneven wall thickness due to gravity, so that the structural performance of the whole pipe is poor. At this moment, the plastic pipe which needs to be extruded immediately enters the cooling system to be cooled, the extrusion die sleeve needs to be fixed at the end of the cooling system at this moment, but the existing extrusion die sleeve is a copper sleeve, the temperature is high during working, the plastic pipe can be stuck on the die sleeve due to the fact that the cooling pipe is not installed, the plastic pipe is not easy to demould and is stuck on the inner wall of the die sleeve, the service life of the die sleeve is shortened, and the quality of the plastic pipe is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a plastic tubing extruder is with extruding die sleeve, cooling to the die sleeve that can be timely has prevented that the material from bonding on the die sleeve, and simple structure has improved the quality of product simultaneously, has prolonged the life of die sleeve.
In order to achieve the purpose, the utility model provides an extrusion die sleeve for a plastic pipe extruder, which comprises a die sleeve body, wherein the exposed end of the die sleeve body is an inlet pipe, the connecting end of the die sleeve body is an outlet pipe, and the outlet pipe is connected with the inlet pipe through a connecting ring;
the outer diameter of the inlet pipe is larger than that of the outlet pipe, the inner diameter of the outlet pipe is the same as that of the inlet pipe, a water inlet nozzle is arranged on the inlet pipe, and the water inlet nozzle is communicated with the inner cavity of the inlet pipe;
the side wall of the outlet pipe is provided with a plurality of water spray holes which are uniformly arranged on the outlet pipe, and the inner cavity of the outlet pipe is communicated with the water spray holes.
Preferably, the length of the outlet pipe is greater than that of the inlet pipe, and the outer wall of the outlet pipe is provided with a plurality of uniformly arranged grooves, and the depth of each groove is 1-3 mm.
Preferably, the number of the water inlets is two, and the water inlets are symmetrically arranged on two sides of the inlet pipe.
Preferably, the diameter of the connection ring is larger than the outer diameter of the inlet pipe, and a plurality of uniformly distributed mounting holes are formed in the edge of the connection ring.
Preferably, the water spraying holes are arranged in a long strip structure and are crossed with the grooves.
Therefore, the utility model adopts the above structure the plastic tubing extruder is with extruding die sleeve, the cooling to the die sleeve that can be timely has prevented that the material from bonding on the die sleeve, and simple structure has improved the quality of product simultaneously, has prolonged the life of die sleeve.
The technical solution of the present invention is further described in detail by the accompanying drawings and examples.
Drawings
FIG. 1 is a schematic structural view of an embodiment of an extrusion die sleeve for a plastic pipe extruder according to the present invention;
fig. 2 is a side view of an embodiment of an extrusion die sleeve for a plastic tube extruder according to the present invention.
Detailed Description
Examples
Fig. 1 is a schematic structural diagram of an embodiment of an extrusion die sleeve for a plastic pipe extruder of the present invention, fig. 2 is a side view of an embodiment of an extrusion die sleeve for a plastic pipe extruder of the present invention, as shown in the drawings, the present invention provides an extrusion die sleeve for a plastic pipe extruder, which comprises a die sleeve body, an exposed end of the die sleeve body is an inlet pipe 1, a connecting end of the die sleeve body is an outlet pipe 2, and the outlet pipe 2 is connected with the inlet pipe 1 through a connecting ring 3; the outer diameter of the inlet pipe 1 is larger than that of the outlet pipe 2, the inner diameter of the outlet pipe 2 is the same as that of the inlet pipe 1, a water inlet nozzle 4 is arranged on the inlet pipe 1, the water inlet nozzles 4 are communicated with the inner cavity of the inlet pipe 1, the two water inlet nozzles 4 are symmetrically arranged on two sides of the inlet pipe 1, a plastic pipe enters the outlet pipe through the inlet pipe, water enters the inlet pipe from the water inlet nozzles in the entering process, and therefore materials can be prevented from being stuck on the pipe wall of the inlet pipe; the side wall of the outlet pipe 2 is provided with a plurality of water spraying holes 5 which are uniformly arranged on the outlet pipe 2, the inner cavity of the outlet pipe 2 is communicated with the water spraying holes 5, when the plastic pipe enters the outlet pipe, the outlet pipe is arranged in a cooling system, water in the cooling system is sprayed on the outer wall of the outlet pipe, and the water can enter the inner part of the outlet pipe through the water spraying holes, so that the movable plastic pipe is isolated from the wall of the outlet pipe, the wall of the outlet pipe is prevented from being adhered, and the quality of the plastic pipe is prevented from being influenced; the length of the outlet pipe 2 is larger than that of the inlet pipe 1, a plurality of uniformly arranged grooves 6 are formed in the outer wall of the outlet pipe 2, and the depth of each groove 6 is 1-3 mm, so that the grooves are conveniently clamped in the cooling device.
