Description

TOP-TIP is with heater loop test device

Technical field

The utility model relates to a kind of TOP-TIP checkout equipment, relates to a kind of to the circulate device of burn-in test of the heater in the TOP-TIP specifically.

Background technology

Compare with traditional cold runner system, the injection mould of TOP-TIP has advantages such as economizing in raw materials, enhances productivity and is extensively adopted, and nozzle is the critical piece in the TOP-TIP.In the 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 heater is carried out performance test, its test mode is: heater is carried out rated voltage energising heating, need be warmed to usually about 250 degree, making the cooling of heater dead electricity, the leading indicator of test is the heats of heater then.And under the condition of production scene, to the energising of heater overload might appear, and; Energising and dead electricity to heater need circulate repeatedly usually; The performance that does not have special equipment that heater is transshipped now and get under the dead electricity cycling condition is tested, and, have now and can only adopt single carrying out the performance test of heater; Do not have autorun, efficient is extremely low.

The utility model content

For overcoming above-mentioned defective; The utility model aims to provide a kind of performance that can transship to heater automatically and get under the dead electricity Automatic Cycle condition and tests, and can carry out the device of the heater circulation burn-in test of performance test simultaneously again simultaneously automatically to a plurality of heaters.

For achieving the above object; The technical scheme that the utility model adopts is: a kind of TOP-TIP is with heater loop test device; Comprise a straight substrate and a control centre of vertically placing, evenly distributing on the said substrate is fixed with some sleeve pipes, and the axis and the substrate of said sleeve pipe are perpendicular; Have several terminals in the said control centre, each terminals have corresponding power switch and ammeter and with corresponding power switch and ammeter control connection.

Said sleeve pipe is a hollow, and the inner chamber of said sleeve pipe is connected with circulating cooling water pipe.

Have in the said control centre voltmeter, testing time table, warm-up time table and cool time table, said voltmeter, testing time table, warm-up time table and cool time table and power switch and ammeter control connection.

The TOP-TIP that has adopted the utility model, is inserted in a plurality of heaters respectively in the corresponding sleeve pipe during concrete operations with heater loop test device; Connect electric wire to terminals; Through control centre heater is carried out the repeatedly circulation of over proof overload voltage energising and dead electricity, the performance that overload voltage can transship to heater as required and get under the dead electricity cycling condition is tested, and compares with traditional test; Because can carry out performance test to a plurality of heaters simultaneously; Improved efficient greatly, and through live press with repeatedly the dead electricity circulation is carried out performance test to heater, more conform to on-the-spot condition of work.

Among the 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 utility model discloses a kind of TOP-TIP with heater loop test device, its innovative point is that mainly it comprises a straight substrate 1 and a control centre 2 of vertically placing; Evenly distributing on the said substrate 1 is fixed with some sleeve pipes 11, and as a rule, the external diameter of said sleeve pipe 11 needs to be complementary with the internal diameter of the heater of being tested 3; Because the internal diameter of heater 3 is different, so, as shown in Figure 3; The external diameter of said sleeve pipe 11 is not identical entirely yet, and the axis of said sleeve pipe 11 and substrate 1 are perpendicular, as a rule; Convenient during for concrete operations, said sleeve pipe 11 is evenly distributed by the size of its diameter on substrate 1.

Have several terminals 21 in the said control centre 2, each terminals 21 have 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 the test, be set to the heater 3 of required test on the corresponding sleeve pipe 11, can overlap one or more heaters 3 on each sleeve pipe 11; Be connected by electrical wiring to each heater 3 on the corresponding terminals 21, power-on switch 22 is generally 5 ~ 20 seconds heat time heating time to the heating of switching on of each heater 3; To each heater 3 outage, make heater 3 coolings then, can set up on their own cool time; After cooling off fully, device 3 to be heated once more it is carried out energising heating about 5 ~ 20 seconds; And then make heater 3 outage coolings, if reciprocation cycle is repeatedly, the number of times of circulation is about 30 times usually.In test process, operating personnel need the data on the recording ammeter 23.

Because heater 3 carries out the speed of nature cooling after outage slower, accelerate for the outage cooling procedure that makes heater 3, as shown in Figure 2, said sleeve pipe 11 is a hollow, the inner chamber of said sleeve pipe 11 is connected with circulating cooling water pipe 12.After heater 3 outages, the inner chamber to sleeve pipe 11 feeds recirculated cooling water through circulating cooling water pipe 12 at once, makes the inner chamber of sleeve pipe 11 have mobile recirculated cooling water, sleeve pipe 11 is cooled off rapidly, thereby the heater 3 that is enclosed within on the sleeve pipe 11 is cooled off rapidly.After device to be heated 3 coolings, stop the inner chamber of sleeve pipe 11 is fed recirculated cooling water, so that make heater 3 heating of switching on once more.

In operating process, to the energising and the dead electricity of 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, in CPU, set certain procedure in advance, the energising and the dead electricity of heater 3 controlled through CPU; Ammeter 23 numerical value are carried out 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 automation; In said control centre 2, also have usually voltmeter 24, testing time table 25, warm-up time table 26 and cool time table 27, said 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 through in testing time table 25, warm-up time table 26 and table 27 pair testing total time cool time, at every turn switch on warm-up time, at every turn cut off the power supply set cool time after; Behind power-on switch 22, the TOP-TIP of the utility model can be realized the performance test to heater 3 automatically with heater loop test device.
