Description
Technical field
The present invention relates to a kind of TOP-TIP checkout equipment, relate to specifically a kind of to the circulated device of burn-in test of the heater in TOP-TIP.
Background technology
With traditional cold runner system, compare, the injection mould of TOP-TIP has the advantages such as economizing in raw materials, enhances productivity and is widely adopted, and nozzle is the critical piece in TOP-TIP.In existing TOP-TIP, extensively adopt the nozzle of jacket-type heater, its version is mainly nozzle body, heater and nozzle head, and heaters set is located on the nozzle body outer peripheral face.Before product export, need carry out performance test to heater, its test mode is: heater carried out to rated voltage energising heating, usually need be warmed to 250 degree left and right, then making the heater dead electricity cooling, the heating effect that the leading indicator of test is heater.And under the condition of production scene, overload likely appears in the energising to heater, and, energising and dead electricity to heater need circulate repeatedly usually, the performance that does not have now special equipment to be transshipped to heater and obtain under the dead electricity cycling condition is tested, and the existing performance test to heater can only adopt single carrying out, there is no autorun, efficiency is extremely low.
Summary of the invention
For overcoming above-mentioned defect, the present invention aims to provide a kind of performance that can automatically to heater, be transshipped and obtain under dead electricity automatic cycle condition and is tested, and can automatically to a plurality of heaters, carry out the device of the heater circulation burn-in test of performance test again simultaneously simultaneously.
For achieving the above object, the technical solution used in the present invention is: a kind of heater circulation test device for hot runner system, comprise substrate and a control centre of vertically placing, be uniformly distributed on described substrate and be fixed with some sleeve pipes, axis and the substrate of described sleeve pipe are perpendicular, there are several terminals in described control centre, each terminals have respectively corresponding power switch and ammeter and with corresponding power switch and ammeter control connection.
Described sleeve pipe is hollow, and the inner chamber of described sleeve pipe is connected with circulating cooling water pipe.
In described control centre, have voltmeter, testing time table, warm-up time table and cool time table, described voltmeter, testing time table, warm-up time table and cool time table and power switch and ammeter control connection.
Adopted heater circulation test device for hot runner system of the present invention, during concrete operations, a plurality of heaters are inserted in respectively in corresponding sleeve pipe, connect electric wire to terminals, by control centre, heater is carried out the repeatedly circulation of over proof overload voltage energising and dead electricity, the performance that overload voltage can be transshipped to heater as required and obtain under the dead electricity cycling condition is tested, with traditional test, compare, because can carry out performance test to a plurality of heaters simultaneously, greatly improved efficiency, and press and repeatedly obtain the dead electricity circulation by live heater is carried out to performance test, more conform to on-the-spot condition of work.

In figure: the 1-substrate, 2-control centre, the 3-heater, the 11-sleeve pipe, the 12-circulating cooling water pipe, the 21-terminals, the 22-power switch, the 23-ammeter, the 24-voltmeter, the 25-testing time is shown, 26-warm-up time table, 27-shows cool time.
The specific embodiment
As shown in Figure 1, the invention discloses a kind of heater circulation test device for hot runner system, its innovative point mainly is that it comprises substrate 1 and a control centre 2 of vertically placing, be uniformly distributed and be fixed with some sleeve pipes 11 on described substrate 1, as a rule, the external diameter of described sleeve pipe 11 need be complementary with the internal diameter of tested heater 3, because the internal diameter of heater 3 is different, so, as shown in Figure 3, the external diameter of described sleeve pipe 11 is entirely not identical yet, the axis of described sleeve pipe 11 and substrate 1 are perpendicular, as a rule, convenient during for concrete operations, described sleeve pipe 11 is evenly distributed by the size of its diameter on substrate 1.
There are several terminals 21 in described control centre 2, each terminals 21 have respectively corresponding power switch 22 and ammeter 23 and with corresponding power switch 22 and ammeter 23 control connections.Usually each terminals 21 is corresponding with the sleeve pipe 11 of row's same outer diameter as.
This device can be tested the heater 3 of a plurality of different inner diameters simultaneously.
During concrete test, the heater 3 of required test is set on corresponding sleeve pipe 11, can overlap one or more heaters 3 on each sleeve pipe 11, each heater 3 is connected by electrical wiring on corresponding terminals 21, power-on switch 22 is to the heating of switching on of each heater 3, be generally 5 ~ 20 seconds heat time heating time, then to each heater 3 outage, make heater 3 cooling, can set up on their own cool time, again it is carried out to energising heating about 5 ~ 20 seconds after device 3 to be heated is fully cooling, and then make heater 3 outages cooling, if reciprocation cycle repeatedly, usually the number of times of circulation is 30 left and right.In test process, operating personnel need the data on recording ammeter 23.
Carry out the cooling speed of nature due to heater 3 slower after outage, accelerate for the outage cooling procedure that makes heater 3, as shown in Figure 2, described sleeve pipe 11 is hollow, and the inner chamber of described sleeve pipe 11 is connected with circulating cooling water pipe 12.After heater 3 outages, the inner chamber of sleeve pipe 11 passed into to recirculated cooling water by circulating cooling water pipe 12 at once, make the inner chamber of sleeve pipe 11 there is mobile recirculated cooling water, make sleeve pipe 11 cooling rapidly, thereby the heater 3 that makes to be enclosed within on sleeve pipe 11 is cooling rapidly.After device 3 to be heated is cooling, stop the inner chamber of sleeve pipe 11 is passed into to recirculated cooling water, in order to make heater 3 heating of again switching on.
In operating process, energising and dead electricity to heater 3, to the record of ammeter 23 numerical value, comprise to the inflow of the inner chamber recirculated cooling water of sleeve pipe 11 with stop, can taking operating personnel's manual operations, certainly, also a CPU can be set in control centre 2, set certain program in advance in CPU, by CPU, energising and the dead electricity of heater 3 be controlled, ammeter 23 numerical value are carried out to automatic record accessing, comprise to the inflow of the inner chamber recirculated cooling water of sleeve pipe 11 with stop.
For realizing that the test of heater 3 is realized to automation; in described control centre 2, usually also have voltmeter 24, testing time table 25, warm-up time table 26 and cool time table 27, described voltmeter 24, testing time table 25, warm-up time table 26 and cool time table 27 with power switch 22 and ammeter 23 control connections.Operating personnel by testing time table 25, warm-up time table 26 and table 27 pair test total time cool time, at every turn switch on warm-up time, at every turn cut off the power supply and set cool time after, after power-on switch 22, heater circulation test device for hot runner system of the present invention can be realized the performance test to heater 3 automatically.
