S5, start corresponding high pressure air rifle, after tamper blows out by the gases at high pressure of high pressure air rifle, enter step S6;
S6, exit support, matched moulds.
Further, also there is step after tamper ejects by the cylinder rod ejecting cylinder in step s 4 which:
S4.1, starting the detector corresponding with ejecting cylinder, detecting in corresponding running channel whether there is tamper, as then entered step 6 without tamper, entering step S4.2 if any tamper;
S4.2, start corresponding high pressure air rifle, after tamper blows out by the high pressure gas of high pressure air rifle, enter step S6.
Beneficial effect of the present invention: convenient to use, by ejecting cylinder or high pressure air rifle is cleared up the tamper in running channel, the continuous casting operation of this three plates structure of cast die can be ensured, improve die casting efficiency and die casting quality, very practical, and before tamper is cleared up, also by detector, tamper detection is carried out to running channel, only needing the running channel to having tamper to clear up specially, saving the energy, reducing cost.
Accompanying drawing explanation
Fig. 1 is the structural representation sketch of using state of the present invention.
Detailed description of the invention
The present invention is further described below in conjunction with specific embodiment and accompanying drawing.
A kind of anti-blockage structure of three plate die castings as described in Figure 1, it comprises the cover half 11 of composition die ontology, intermediate die 12 and dynamic model 15, between this intermediate die 12 and dynamic model 15, there is die casting die cavity, rising head on cover half 11 is connected with die casting die cavity by the running channel 14 in intermediate die 12, the support 16 between cover half 11 and intermediate die 12 can be stretched to after also including die sinking simultaneously, this support 16 is provided with and can faces one by one with running channel 14 and the detector 17 that whether there is tamper 13 in running channel 14 can be detected, and can face one by one with running channel 14 and the tamper 13 in running channel 14 can be ejected or blows out eject cylinder and high pressure air rifle.
The present invention is convenient to use, by ejecting cylinder or high pressure air rifle is cleared up the tamper 13 in running channel 14, the continuous casting operation of this three plates structure of cast die can be ensured, improve die casting efficiency and die casting quality, very practical, and before tamper 13 is cleared up, also carry out tamper 13 by detector 17 pairs of running channels 14 to detect, only needing the running channel 14 to having tamper 13 to clear up specially, saving the energy, reducing cost.
Detector 17 includes infrared ray or sensor, and both all can detect the tamper 13 in running channel 14, certainly in actual applications, also have other detector and bridge breaker, do not point out one by one at this.
The present invention also includes controller, this controller and detector 17, ejects cylinder, high pressure air rifle all electrically control connection; Detector 17 detects in corresponding running channel 14 whether have tamper 13, and controller, according to testing result, controls to eject cylinder and ejected by the tamper 13 in corresponding running channel 14, or the tamper 13 in corresponding running channel 14 blows out by control high pressure air rifle.This behavior of method for opening and closing controlling to eject cylinder or high pressure air rifle by the testing result of detector 17 for controller belongs to prior art, universal use in existing industrial production.
Finally, what detector 17 was corresponding with it eject cylinder, high pressure air rifle is connected mutually, and this detector 17, eject cylinder, high pressure air rifle is mutually non-interference, certainly, in actual applications, this detector 17 and the positional structure relation ejected between cylinder, high pressure air rifle can use according to reality and specifically arrange.
The invention also discloses the using method of three plate die casting anti-blockage structures, it includes step:
Die sinking after S1, die casting complete, cover half 11, intermediate die 12 and dynamic model 15 are separated from each other;
S2, support 16 to be stretched between cover half 11 and intermediate die 12, and make detector 17, eject cylinder, running channel 14 in high pressure air rifle and intermediate die 12 is just right one by one;
Whether S3, start-up detector 17, having tamper 13 in the running channel 14 detecting its correspondence, as entered step S6 without tamper 13, entering step S4 or S5 if any tamper 13;
S4, start and eject cylinder accordingly, after tamper 13 ejects by the cylinder rod ejecting cylinder, enter step S6;
S5, start corresponding high pressure air rifle, after tamper 13 blows out by the gases at high pressure of high pressure air rifle, enter step S6;
S6, exit support 16, matched moulds.
By ejecting cylinder to when tamper 13 ejects in running channel 14, likely because the length of cylinder rod causes tamper 13 to be still in running channel 14 not, after tamper 13 ejects by this cylinder rod ejecting cylinder in step s 4 which, also there is step:
S4.1, starting the detector 17 corresponding with ejecting cylinder, detecting in corresponding running channel 14 whether there is tamper 13, as entered step 6 without tamper 13, entering step S4.2 if any tamper 13;
S4.2, start corresponding high pressure air rifle, after tamper 13 blows out by the high pressure gas of high pressure air rifle, enter step S6.
