Abstract
The utility model provides a heating synchronous shutdown circuit of an injection molding machine mould hot runner and an injection molding machine. The heating synchronous shutdown circuit comprises an injection molding machine electric heating control contactor, a control switch of a hot runner power supply and an under-voltage tripping module, wherein the control switch of the hot runner power supply and the under-voltage tripping module are connected with the injection molding machine electric heating control contactor by a normally open auxiliary contact of the injection molding machine electric heating control contactor. The existing control switch of the hot runner power supply and the under-voltage tripping module are connected with the injection molding machine electric heating control contactor by the normally open auxiliary contact of the injection molding machine electric heating control contactor, and the heating synchronous shutdown of the injection molding machine mould hot runner and the injection molding machine can be realized under the condition of not increasing previous elements of the injection molding machine, so that the heating synchronous shutdown circuit is simple in structure and low in cost.
Description
Technical field
The utility model relates to a kind of injection machine of installation mold hot flow path temperature control requirement.
Background technology
At present injection machine to himself with mold hot flow power supply control, by what strengthen that controller of plastic injection molding carries, mould shell switch, more directly connect injection machine and hot flow path is moulded the control that shell switch carries out injection machine mould hot flow path with cable.Owing to need to strengthening injection machine and mould the capacity of shell switch, also needing increases the cable connecting, so price comparison is expensive.
Summary of the invention
The purpose of this utility model provides a kind of injection machine mould hot flow path and injection machine heating turned off in synchronization loop for the above-mentioned deficiency of prior art, while making it cut off hot flow path power supply on injection machine, do not need to increase in addition button, accomplish the object of injection machine heater and hot flow path turned off in synchronization.
The utility model solves the problems of the technologies described above adopted technical scheme: injection machine mould hot flow path and injection machine heating turned off in synchronization circuit, the gauge tap and the undervoltage tripping module that comprise injection molding machine electric heating control contactor, hot flow path power supply, be connected the gauge tap of hot flow path power supply and undervoltage tripping module with the auxiliary contact of often opening of injection molding machine electric heating control contactor by injection molding machine electric heating control contactor.
Because injection machine electric heating control contactor is connected with hot flow path heating circuit, the electric heating control contactor of injection machine can be controlled hot flow path power supply, therefore the out-of-work power supply that simultaneously cuts off hot flow path heating circuit of injection machine heater circuit, also synchronously stops hot flow path heating.
The beneficial effects of the utility model: because the gauge tap by existing hot flow path power supply is connected with the auxiliary contact of often opening on injection molding machine electric heating control contactor with undervoltage tripping module, in the situation that not increasing the original element of injection molding machine, can reach injection machine mould hot flow path and injection machine heating turned off in synchronization, therefore it is simple in structure, and cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
As shown in Figure 1, a kind of heating device for plasticizing machine cuts off the connecting circuit of hot flow path power supply, has comprised injection molding machine electric heating control contactor 1, the gauge tap of hot flow path power supply and the connecting circuit 2 that undervoltage tripping module 3, injection molding machine and hot flow path are controlled power supply.
The connecting circuit that heating device for plasticizing machine cuts off hot flow path power supply has adopted the original control device of injection molding machine, the out-of-work power supply that simultaneously cuts off hot flow path heating circuit of injection molding machine heater circuit.
From No. 8 lines of 220V power supply of injection machine be connected to injection machine heating control contactor KH1 often open auxiliary contact 13 14, be connected to the undervoltage tripping module 3 of the breaker of plastic casing of hot runner controller, after under-voltage de-mouthful of module coil forms load circuit, return the power supply common port of injection machine.
When heating contactor (load is below injection machine heater) because of host computer to signal cut coil power after, the normally opened contact of contactor disconnects, under-voltage de-mouthful of module of hot runner controller causes moulding shell switch trip and disconnects because dead electricity is under-voltage, cut off hot flow path power supply, thereby realize the synchronous disconnection of the power supply of hot flow path control cabinet and the firing equipment of injection machine.
Claims (1)
1. injection machine mould hot flow path and injection machine heat turned off in synchronization circuit, the gauge tap and the undervoltage tripping module that comprise injection molding machine electric heating control contactor, hot flow path power supply, is characterized in that: the gauge tap of described hot flow path power supply and undervoltage tripping module are connected with the auxiliary contact of often opening of injection molding machine electric heating control contactor by injection molding machine electric heating control contactor.
