after the controller 22 is started, the steam generator 5 is immediately controlled to work, and meanwhile, each magnetic pushing electromagnet 30 is controlled to work, the steam generator 5 can convey high-temperature steam into the steam supply cavity 7 through the steam pipe 6, then the high-temperature steam can enter the cavity through the two steam exhaust holes 8 and the injection holes of the injection mold 2 to be detected, then the high-temperature steam can be discharged from each exhaust structure of the injection mold 2 to be detected through the cavity, the high-temperature steam can heat the injection mold 2 to be detected from the inside when passing through the cavity, after the magnetic pushing electromagnets 30 are electrified to work, the corresponding permanent magnets 24 are pushed to drive the T-shaped insulating rods 23 to move to the outer sides of the circular grooves 212 under the action of like-polarity repulsion, so that the insulating heat conducting blocks 213 can be pushed to abut against the side walls of the injection mold 2 to be detected through the heat sensitive elements 214, after the magnetic pushing electromagnets 30 are started by the controller 22, the power is synchronously supplied to the serial circuit of the thermosensitive element 214 and the active electromagnetic switch 216, and the power is periodically supplied to the connection circuit of the delay power-off relay 217, the active electromagnetic switch 216 and the buzzer 218 for 2 seconds at the 10 th second after the magnetically pushed electromagnet 30 is started, the heat generated by the high-temperature steam is transferred to each insulating heat conducting block 213 through the mold cavity and is transferred to each thermosensitive element 214 through each insulating heat conducting block 213, so that the temperature of each thermosensitive element 214 can be raised, the temperature of the thermosensitive element 214 is raised to synchronously raise the resistance value of the thermosensitive element 214, and at the beginning, the temperature of the thermosensitive element 214 is not raised, the resistance value of the thermosensitive element 214 is lower, so that the current which is introduced into the active electromagnetic switch 216 at the beginning of the power-on of the thermosensitive element 214 and the active electromagnetic switch 216 is larger, at the moment, the movable contact of the active electromagnetic switch 216 keeps the magnetic attraction closed state, if the heat transfer performance of the injection mold 2 to be detected is good, the temperature transferred to each heat-sensitive element 214 in 10 seconds before the buzzer 218 is electrified is high, at this time, the resistance value of each heat-sensitive element 214 is high, so when the controller 22 supplies power to the connection loop of the delay power-off relay 217 and the active electromagnetic switch 216 and the buzzer 218, as the resistance value in the series circuit of the heat-sensitive element 214 and the active electromagnetic switch 216 is high, the moving contact of the active electromagnetic switch 216 is rebounded and reset because the electrified current is too small, so that the connection loop of the delay power-off relay 217 and the active electromagnetic switch 216 and the buzzer 218 is kept in an open state, at this time, the buzzer 218 is not electrified, if the heat transfer performance of the injection mold 2 to be detected is poor, the heat quantity at the transfer value of each heat-sensitive element 214 is insufficient, and the resistance value of each heat-sensitive element 214 is less increased, when the controller 22 supplies power to the connection loop of the delay power-off relay 216 and the buzzer 218, the moving contact of the active electromagnetic switch 216 keeps in a closed state, and the buzzer 217 is still connected with the buzzer 218, and the alarm is not closed, and the temperature of the alarm 2 is required to be cooled after the injection mold is cooled, and the alarm 2 is not cooled, and the alarm is not required to be cooled, and the alarm is not cooled is properly cooled after the alarm is started;
after the controller 22 is started for 1 minute, since the high-temperature steam has sufficiently heated the injection mold 2 to be inspected, condensation phenomenon does not occur in the high-temperature steam entering the injection mold 2 to be inspected at this time, so that the high-temperature steam can be stably discharged from each exhaust structure of the injection mold 2 to be inspected, at this time, the controller 22 can start each first light source 142, and after 5 seconds, power is supplied to each first photosensitive element 144 and the corresponding normally open electromagnetic switch 27 and normally closed electromagnetic switch 28, and three conditions exist at this time:
first case: the exhaust structure of the injection mold 2 to be detected is normal, at this moment, under the action of high temperature and high pressure, steam is sprayed out through the exhaust structure to form columnar air flow and is diffused after passing through the detection hole 13, because the steam can block the light irradiated to the first photosensitive element 144 to a certain extent when passing through the inside of the detection hole 13, the first photosensitive element 144 can raise the resistance of the first photosensitive element 144 because of the reduction of illumination intensity, the coverage area of the air column formed by the steam spraying is proper, at this moment, the resistance of the first photosensitive element 144 is raised to a proper value, when the first photosensitive element 144 is electrified with the corresponding normally open electromagnetic switch 27 and normally closed electromagnetic switch 28, a sufficient large current is not electrified into the normally open electromagnetic switch 27, so that under the normal condition of the exhaust structure, the normally open electromagnetic switch 27 keeps the normally open state, thereby keeping the connection loop of the normally open electromagnetic switch 27 and the corresponding indicator lamp 29 to be disconnected, at this moment, the normally closed electromagnetic switch 28 can not be electrified, and the normally closed electromagnetic switch 28 can magnetically attract the moving contact of the first photosensitive element because of the sufficient current is electrified, thereby making the normally closed electromagnetic switch 28 and the corresponding indicator lamp 29 to be disconnected, and all the normally open under the conditions of the injection mold 29 can not normally be normally lighted;
second case: the exhaust structure of the injection mold 2 to be inspected is blocked, because the exhaust structure is blocked, the coverage area of a steam column discharged through the exhaust structure is reduced (when the exhaust structure is completely blocked, no steam is discharged from the exhaust structure), so that the light blocking of the steam to the first light source 142 is reduced, the illumination intensity of the corresponding first photosensitive element 144 is increased, the resistance of the first photosensitive element 144 is reduced more, at the moment, the current flowing into the normally open electromagnetic switch 27 and the normally closed electromagnetic switch 28 is increased, so that enough current can be led into the normally open electromagnetic switch 27, the moving contact of the normally open electromagnetic switch 27 is magnetically closed, the corresponding indicator lamp 29 is lightened, and because the current flowing into the normally closed electromagnetic switch 28 is also increased, the moving contact of the normally closed electromagnetic switch 28 still keeps the suction state, and at the moment, the corresponding indicator lamp 29 is still not lightened, so that after a person checks that the corresponding indicator lamp 29 of the normally open electromagnetic switch 27 is lightened, the exhaust structure at the position is blocked;
third case: the aperture of the exhaust structure of the injection mold 2 to be detected is increased due to abrasion, the coverage area of the steam gas column discharged through the exhaust structure is increased due to the increase of the aperture of the exhaust structure, at the moment, more light rays are blocked when steam passes through the detection hole 13, so that the light intensity projected to the first photosensitive element 144 is lower, at the moment, the resistance of the first photosensitive element 144 keeps a higher state, at the moment, the current flowing into the normally open electromagnetic switch 27 and the normally closed electromagnetic switch 28 is reduced, so that the corresponding indicator lamp 29 cannot be lightened due to the fact that enough current cannot be flowing into the normally open electromagnetic switch 27, and the magnetic attraction of the normally closed electromagnetic switch 28 is weakened due to the fact that the current flowing into the normally closed electromagnetic switch 28 is also reduced, so that the moving contact of the normally closed electromagnetic switch cannot be adsorbed, the corresponding indicator lamp 29 is lightened, and a worker can explain that the phenomenon of the exhaust structure exists after the fact that the normally closed electromagnetic switch 28 is lightened is checked;
at 2 nd minute of starting of the controller 22, the controller 22 will stop the steam generator 5 and simultaneously start each electric control gate valve 164, so that each electric control gate valve 164 seals each detection hole 13, then, the controller 22 will start the electric heating plate 166, during the operation of the electric heating plate 166, the controller 22 will start the motor pump 161 and firstly control the second normally closed solenoid valve 204 in the shunt tube 203 and the normally open solenoid valve 205 in the water delivery main tube 162 to electrify for 20 seconds at regular time, at this time, the motor pump 161 can convey the quantitative water 15 to the inside of the liquid storage cavity 201 through the water delivery main tube 162 and the shunt tube 203, so that the quantitative water 15 is stored in the liquid storage cavity 201, and after the timing operation of the second normally closed solenoid valve 204 and the normally open solenoid valve 205 is finished, the motor pump 161 can pump the water 15 heated by the electric heating plate 166 and enter each detection hole 13 through the water delivery main tube 162, the water delivery hose 163 and the communication tube 165, then the water 15 will enter the cavity of the injection mold 2 to be inspected reversely through each inspection hole 13, because the high temperature steam can be utilized to make the residual sizing material adhered in the cavity change from the hardening state to the melting state when passing through the cavity of the injection mold 2 to be inspected, after the high temperature water 15 is introduced, the residual sizing material in the melting state can flow into the steam supply cavity 7 through the injection holes of the injection mold 2 to be inspected, when the controller 22 starts the pump 161, the controller 22 also starts the first normally closed electromagnetic valve 19 in the reflow hole 17 synchronously, and starts the two second light sources 182 simultaneously, and supplies power to the connecting loop of the third normally closed electromagnetic valve 207 and the second photosensitive element 183 for 15 seconds at regular time, the opening and closing degree of the third normally closed electromagnetic valve 207 increases with the increase of the introduced current, otherwise decreases, if there is more residual glue in the injection mold 2 to be inspected, more impurities in the water solution 15 flowing back through the backflow hole 17 are more, at this time, the light of the second light source 182 is blocked more, so the light intensity projected to the second photosensitive element 183 is lower, at this time, the resistance introduced into the second photosensitive element 183 is increased, so the current introduced into the third normally closed electromagnetic valve 207 is reduced, at this time, the opening degree of the third normally closed electromagnetic valve 207 is reduced, so the water solution 15 discharged through the liquid discharge hole 206 is less, therefore, after the timing energization of the third normally closed electromagnetic valve 207 is finished, the water level in the liquid storage cavity 201 remains in a higher state, otherwise, if the state of the injection mold 2 to be inspected is better, the water solution 15 flowing back through the backflow hole 17 is relatively clear, at this time, the current introduced into the third normally closed electromagnetic valve 207 is increased, the opening degree of the third normally closed electromagnetic valve 207 is increased, thereby the water level in the liquid storage cavity 201 is reduced more, the personnel can judge the residual glue amount in the injection mold 2 to be inspected through the numerical value of the liquid level meter 202, otherwise, if there is excessive wear and the residual glue in the injection mold 2 to be inspected;
so far, the detection of the single injection mold 2 to be detected is completed, the controller 22 controls all the power-on devices to be disconnected firstly, controls the electric push rod 9 to carry out the timed output end extending work until the mounting frame plate 11 moves upwards to reset, and then the personnel can take out the injection mold 2 to be detected, and can further repair the injection mold 2 to be detected according to the detection result.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
