Abstract
The utility model relates to a pin on an injection moulder, which is the improvement based on the pin in the prior art; the inner part of the pin body is provided with a slot along an axis direction, the slot is provided with an electric heating rod, and the electric heating rod can carry out power supply through a slip ring and a carbon brush; the supplementary central heating pin for the injection moulder has the advantages of simple structure, and convenient operation; when heating source is insufficient, the supplementary central heating pin for the injection moulder can be used as the supplementary heating source for heating plastics, because the pin is positioned on the center part of the heated plastic raw materials, and transferred heat can be basically and entirely absorbed by the plastics; the supplementary central heating pin for the injection moulder has small radiation loss, and the heat utilization ratio can be improved.
Description
The utility model relates to a kind of injection machine, the screw rod on particularly a kind of injection machine.
In injection machine, plastic raw materials is heated in heat exchanger after entering feed space by hopper.Screw rod in the heat exchanger advances raw material, and stirs, in order to avoid each several part heat inequality.Injection machine generally is externally to carry out electrical heating, thus thermal loss takes place unavoidably, so that efficient reduces.And this because heat loss or because of heat source insufficiency does not usually reach desired drop temperature directly influences product quality, brings very big loss to production.
The purpose of this utility model will provide a kind of injection machine sectional center heating spiral rod exactly, it can heat plastics as auxiliary heating source when heat source insufficiency, screw rod is positioned at the centre of heated plastic raw materials, the heat that is transmitted can all be absorbed by plastics substantially, radiation loss is minimum, thereby can improve heat utilization ratio.
For achieving the above object, the utility model adopts technical scheme as described below: a kind of injection machine sectional center heating spiral rod, and there is screw channel the outside of the screw rod body of rod, and the inside of the screw rod body of rod is equipped with an electrically heated rod along a slotted hole is arranged on the axis direction in the hole.
End at the screw rod body of rod is provided with a slip ring and carbon brush, and electrical bar is powered.On perpendicular to the screw axis direction, there is an exhaust fairlead that communicates with slotted hole to make inside and outside gas pressure balancing.
Adopt the utility model of said structure simple in structure, easy to operate, it can heat plastics as auxiliary heating source when heat source insufficiency, and because screw rod is positioned at the centre of heated plastic raw materials, the heat that is transmitted can all be absorbed by plastics substantially, radiation loss is minimum, so can greatly improve heat utilization ratio.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
With reference to Fig. 1.A kind of injection machine sectional center heating spiral rod, there is screw channel 8 outside of the screw rod body of rod 1, makes the material homogeneous heating and extrudes, and the inside of the screw rod body of rod 1 is equipped with an electrically heated rod 3 along a slotted hole 2 is arranged on the axis direction in the hole.If material does not reach desired temperature, assist heating with regard to available electrically heated rod.End at the screw rod body of rod 1 is provided with a slip ring 5 and 6 pairs of electrically heated rod power supplies of carbon brush.On perpendicular to the screw axis direction, there is an exhaust fairlead 4 that communicates with slotted hole 2 to make inside and outside gas pressure balancing.The screw 7 of screw rod end prevents that electrical bar from scurrying out.
