Description
Technical field
The utility model relates to a kind of Plastic Profile Extrusion Dies for extrusion moulding special shapes, specifically a kind of energy-saving type plastic Profile Extrusion die head.
Background technology
Plastic Profile Extrusion Dies is the key equipment of plastic profile extrusion machine, and its effect is that the plastics of melting are formed parison close to article shape gradually by the shunting compression stage such as grade.For the polymer melting of powdery or granular form is become glutinous fluid, die head sidewall surrounding need arrange heater, heats die head.Heater the most frequently used is at present made up of aluminium base heating plate and the panel be made up of steel plate being arranged on heating plate outer surface, and heating plate is built-in with the resistance wire for heating, and panel is for the protection of heating plate.The advantage of the heater of this form is compact conformation, takes up room little, can not increase the volume of die head; Shortcoming is effect of heat insulation heterodyne, and the heat that heating plate produces runs off in a large number in air, causes the waste of large energy, and makes heater plate surface temperature become abnormal high in the process of distributing at energy, may bring the problems such as scald to processor; In addition, because heater element resistance wire is preset in heating plate, once damaging appears in resistance wire, whole heating plate can not continue to use, and must change, cause production cost to increase, also can bring inconvenience to production process.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and provide a kind of energy-saving type plastic Profile Extrusion die head, the heater thermal loss adopted is little, and heater element is easy to change, and can reduce production cost.
For achieving the above object, the utility model have employed following technical scheme: comprise die head body and be fixed on the heater of die head body sidewall, and described heater comprises aluminium base heating plate and is arranged on the thermal insulation layer of heating plate outer surface; The heating plate side sidewall corresponding to die head body sidewall has several parallel distribution, is used for installing the jack of electrical bar, an electrical bar is installed in each jack; The cooling system be made up of an inlet channel and several exhaust passages is provided with in heating plate, described inlet channel is arranged in the heating plate that do not communicate with electrical bar jack, the air inlet of inlet channel is arranged on the heating plate sidewall corresponding to die head exit end, exhaust passage is parallel to the distribution of electrical bar jack, the medial extremity of exhaust passage communicates with inlet channel, and exhaust outlet is arranged on on the heating plate sidewall of electrical bar jack openings end homonymy or the heating plate sidewall reverse with the jack installing electrical bar; Described thermal insulation layer is made up of base plate and the surrounding Rigid Plates Under Compression with frame, and base plate is made up of high-temperature-resistant thermoplastic material, is filled with asbestos in the cavity between pressing plate and base plate.
For lowering the temperature to heating plate rapidly, heating plate is respectively equipped with exhaust passage in each electrical bar jack both sides.
Because the base plate of thermal insulation layer directly contacts with heating plate, consider the high temperature resistant of material and rigidity factor, described base plate adopts polyether-ether-ketone plate.
For convenience of the electrical bar external power supply in heating plate, the socket for external power supply is fixed with outside thermal insulation layer, heating plate upper end has the wire casing leading to electrical bar electrode area, the base plate of thermal insulation layer and pressing plate have the through hole communicated with wire casing, and each electrical bar is electrically connected with the electrode in socket by the wire casing of wire on heating plate and the through hole on thermal insulation layer.
For reducing the thermal loss of heating plate further, outside described thermal insulation layer, being also provided with one deck polyfluortetraethylene plate, polyfluortetraethylene plate having the through hole passed through for wire.
The beneficial effects of the utility model are: one is that heater element is changed conveniently.Electrical bar is mounted in heating plate by jack, for the electrical bar damaged, only need change corresponding electrical bar, and do not need to change whole hot table, use cost obviously reduces.Two is that thermal loss is little.Heating plate outer surface arranges insulating layer of asbestos, and externally environment is lost can to prevent heat preferably, can not only reduce power consumption, save electric energy, reduce production cost.Three is to enhance productivity.Owing to being provided with cooling system in heating plate, after heating plate end-of-job, by blowing to inlet channel, fast the heat in heating plate can be taken away, heating plate is cooled rapidly, the detachable maintaining speed of heating plate can be accelerated, can greatly enhance productivity.In addition, thermal insulation layer be arranged so that heating plate thermal loss reduces, the programming rate of die head can be accelerated, reduce time of die head, thus enhance productivity.
