1. traditional mould top layer bush structure oil circulating cooling method is only adopted in the cooling of the mold core of prior art.
2. oil cooling can not effectively effectively cool off the extruding pipe material inwall, only the mould internal layer is carried out heat exchange, can not effectively improve extrusion efficiency.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of tubing extrusion die core highly efficient cooling device, can make goods improve cooling capacity and production efficiency in extrusion.
For achieving the above object, the utility model proposes a kind of tubing extrusion die core highly efficient cooling device, comprise middle plug, in plug be provided with separate passage and the center cavity extruded, the central part of center cavity is equipped with forced air cooled tube, the outside of forced air cooled tube is coated with attemperator, the inwall of middle plug is provided with cooling jacket, the end of cooling jacket is connected with into return water system, describedly advance return water system and be located in the space between cooling jacket and the attemperator, the inlet portion of forced air cooled tube is connected to blower fan, export department with communicate by the inwall of extruding the extruding pipe that passage extrudes.
As preferably, the export department of described forced air cooled tube is provided with volume adjusting apparatus.
As preferably, the export department of described forced air cooled tube is pre-large post-small taper, volume adjusting apparatus comprise screw rod, with the corresponding conical plug of taper of forced air cooled tube export department, described conical plug is fixed on the screw rod.
As preferably, be provided with heater between described middle plug and the cooling jacket.
As preferably, the first half of described cooling jacket has some independently aquaporins, and the Lower Half of cooling jacket also has some independently aquaporins.
The beneficial effects of the utility model:
1. independently air cooling system is a kind of novel cooling system, installs more convenient in the process of using.Volume adjusting apparatus by different size change to be installed can effectively make tubing cool down rapidly when extruding super abundant wall tube material, reduces the configuration of vacuum tank and spraying box equipment, improves pipe extruded velocity and quality.As: the tube outer diameter diameter is 500mm, and thickest can only be accomplished 68.3mm in the prior art, and after adopting the utility model, thickest can be accomplished 83.3mm; The tube outer diameter diameter is 160mm's, and thickest can only be accomplished 21.9mm in the prior art, and after adopting the utility model, thickest can be accomplished 26.6mm; Improved the range of application and the service life of tubing so greatly, the development of extruding pipe material industry has been had facilitation.
2. when extruding super abundant wall tube material, because the influence that is subjected to gravity factor of raw material itself, temperature about causing in the mold cavity is difference to some extent, this moment the mold core temperature constantly regulating system by analysis to real time data, can open water-cooling circulating system or heating system automatically, guarantee the uniformity of mould extrusion type cavity temperature.
3. when improving the mold core cooling system, also improved the structure of existing mold, original solid mould middle part is processed as the through hole state, itself increased the contact area of die cavity and outside air, the place also is improved the radiating condition of mould self, when the stretching thin-wall pipes, can improve draw speed greatly, can improve stretching efficient when stretching super abundant wall tube material.
Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
