Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of protection of the invention.
Refer to Fig. 1, Fig. 1 is the first embodiment intelligence method for adjusting mould flow chart provided by the invention.As shown in Figure 1, the die casting machine intelligence method for adjusting mould that the embodiment of the present invention provides comprises the following steps:
S1, mould of die casting machine die face be adjacent to, mode transfer electronic eye response device obtains mode transfer pulse;
S2, Programmable Logic Controller receive described mode transfer pulse and obtain current clamp force;
S3, Programmable Logic Controller control mode transfer system automatic mold-adjustment according to current clamp force.
From the intelligent method for adjusting mould that the present embodiment provides, intelligent method for adjusting mould provided by the invention is on the basis of existing intelligent mode transfer system, mode transfer pulse is detected by mode transfer electronic eye response device, and then calculate current clamp force according to mode transfer pulsimeter, and then send accurate control signal according to current clamp force, mode transfer system is made once to complete automatic mold-adjustment process in control signal effect, without the need to repeatedly finely tuning.The intelligent method for adjusting mould that the present embodiment provides not only does not need the clamp force detector of specialty to detect current clamp force, and the control signal sent can make mode transfer one-time-reach-place, realize automation mode transfer process, enormously simplify the structure of die casting machine mode transfer system, save cost, and simple to operate, automaticity is high, improve mode transfer efficiency, thus save the mode transfer time.
Refer to Fig. 2, Fig. 2 is the second embodiment intelligence method for adjusting mould flow chart provided by the invention.As shown in Figure 2, in order to further illustrate the intelligent mode transfer process of the first embodiment, on above-mentioned first embodiment basis, this gives another preferred intelligent method for adjusting mould, specifically comprising the following steps:
S11, mode transfer electronic eye response device detect the position of pinion rotation in adjusting device;
S12, mode transfer electronic eye response device calculate current molar amount;
Molar amount refers to that lock die-sinking machine hinge stretches the distance of rear middle plate and head plate; Actual and the relative position of each parts needing during the position calculation molar amount of mode transfer electronic eye response device according to pinion rotation to utilize lock die sinking electronic ruler to provide;
S13, mode transfer electronic eye response device export the mode transfer pulse of respective amount to Programmable Logic Controller according to molar amount;
S2, Programmable Logic Controller receive mode transfer pulse and obtain current clamp force;
