Abstract
The utility model discloses a heating device for extrusion dies. The heating device comprises a die holder. A die support is disposed on one side of the die holder. A front die and a rear die are correspondingly disposed on the other side through a die sleeve. Anti-rotating keybars are disposed among the die holder, the die support and the die sleeve. A plurality of electric heating tubes are mounted on the die holder. Line guide grooves matched with outgoing lines of the electric heating tubes are reserved on the die holder. The outgoing lines of the electric heating tubes are guided out through the line guide grooves. A heating tube cover plate is mounted above the electric heating tubes on the die holder. A die retaining ring is mounted between the die sleeve and the die holder. The heating device is effective and even in heating, and the outgoing lines of the electric heating tubes are safe and reliable in structure.
Description
Technical field
The utility model relates to the extruder technical field, relates in particular to a kind of heater of extrusion die of extruder.
Background technology
At present, for some magnesium-alloy material, can not squeeze for preventing that mold cools down from causing, in extrusion process, need heat mould.Traditional mode of heating generally adopts dual mode: first kind of way: by die sleeve is heated the heat transferred mould.Advantage: mould is heated more even, shortcoming: die sleeve need to than large space and heating lead-out wire, have potential safety hazard.The second way: by die holder is heated, the heat transferred mould.Advantage: the heating lead-out wire is safer, shortcoming: only the die holder bottom is heated that to cause mould to be heated inhomogeneous, affect magnesium alloy profiles and extrude.
The utility model content
The purpose of this utility model is to provide a kind of extrusion die heater, and it has homogeneous heating and the safe and reliable characteristics of heating lead-out wire, to solve the problem that the extruder extrusion die exists in the prior art.
For reaching this purpose, the utility model by the following technical solutions:
A kind of extrusion die heater, it comprises die holder, one side of described die holder arranges mould and supports, be provided with forward and backward mould corresponding to opposite side by die sleeve, and between described die holder and mould support and the die sleeve antirotation keys rod be set, wherein, many electric heating tubes are installed on the described die holder, cooperate the lead-out wire of electric heating tube to offer wire lead slot on die holder, the lead-out wire of described electric heating tube is drawn from wire lead slot, and the heating tube cover plate is installed in the top in electric heating tube on the described die holder.
Especially, installation mold back-up ring between described die sleeve and the die holder.
Especially, the top of described mould support is provided with the shifting formwork slide block.
The beneficial effects of the utility model are that compared with prior art not only heating effect is good, homogeneous heating for described extrusion die heater, and the leading-out wire structure of electric heating tube is safe and reliable.
