Detailed description of the invention
Fig. 1, Fig. 2, Fig. 3 are that the present invention illustrates figure.
As shown in Figure 1, a kind of mold stroke controls formula cylinder core drawing mechanism, comprises the first lead limit switch 1, adjustable diameter and screw adjusting handle 2, second lead limit switch 3, travel switch mounting plate 4, spacing regulating block 5, wearing plate 6, type pin 7, slide body 8, guiding stick 9, cylinder mounting plate 10, cylinder 11, travel screw 12, backing plate 13;
As shown in Figure 2, described first lead limit switch 1, second lead limit switch 3 is installed on travel switch mounting plate 4 by screw; Travel switch mounting plate 4 is installed on cylinder mounting plate 10 by screw fastening; Slide body 8 is installed on backing plate 13 by guiding stick 9, and be provided with wearing plate 6 under slide body 8, type pin 7 is inlayed and is installed on slide body 8; On travel screw 12, one end is provided with adjustable diameter and screw adjusting handle 2, and one end connects with slide body 8 through travel switch mounting plate 4 and cylinder mounting plate 10 in addition; Cylinder 11 is installed on cylinder mounting plate 10 by screw, and is connected with slide body 8 by T-slot; Spacing regulating block 5 is installed on cylinder mounting plate 10;
The control signal source component of described first lead limit switch 1, adjustable diameter and screw adjusting handle 2, second lead limit switch 3, travel switch mounting plate 4, composition cylinder 11; Described wearing plate 6, type pin 7, slide body 8, guiding stick 9, cylinder mounting plate 10, cylinder 11, travel screw 12 form cylinder core drawing action component;
Described mechanism utilizes travel switch control cylinder to loose core; by type pin extended length; and blocking design treatment is carried out to slide block cylinder core drawing mould emptier; mechanism can make in good time adjustment according to the abrasion condition of type pin to core pulling distance; described mechanism is a kind of unit-modularized mechanism; monoblock type can assemble and dismounting, recycle.
During real work, as shown in Figure 3, in Fig. 3, L0 is that type pin initially assembles length, and L1 is that L0 weares and teares the length after Δ S1 for the first time, and Ln is that L0 weares and teares the length after Δ Sn, S0 is the initial position of adjustable diameter and screw adjusting handle 2 on travel screw 12, and S1 is the position of type pin wearing and tearing Δ S1 rear screw regulating handle 2 on travel screw 12 after adjustment, and Sn is the position of type pin wearing and tearing Δ Sn rear screw regulating handle 2 on travel screw 12 after adjustment, the contact of M second lead limit switch 3, N is the contact of the first lead limit switch 1, during work, single is loosed core action, core 7 core pulling distance is determined by the distance controlled between M and N of contact, concrete action is, as shown in Figure 3, when loosing core, cylinder 11 obtains instruction, cylinder 11 is extracted type pin 7 out to the right from plastic products in mold cavity, after adjustable diameter and screw adjusting handle 2 is pressed onto control contact N, cylinder 11 loose core action stop, during reset, cylinder 11 obtains reset instruction, left type pin 7 is pushed in the cored hole of position corresponding to it, after adjustable diameter and screw adjusting handle 2 is pressed onto control contact M, cylinder 11 homing action stops, mould closes, wait injection cycle starts.
In order to ensure the service life of type pin 7, during actual use, as shown in Figure 3, the initial length of setting type pin 7 is L0, now, adjustable diameter and screw adjusting handle 2 adjusts S0 point position on travel screw 12, when after work a period of time, due to wearing and tearing, the length of type pin 7 becomes L1, wears away Δ S1, now, for the result of use of guarantee type pin 7, correspondingly adjustable diameter and screw adjusting handle 2 is adjusted to S1 position on travel screw 12 after S0 adjusts Δ S1 length; Correspondingly, the like, type pin 7 weares and teares after Δ Sn, then adjustable diameter and screw adjusting handle 2 should adjust Δ Sn length to Sn position on travel screw 12, thus in actual production, does not do long-time maintenance after reaching type pin 7 wearing and tearing and safeguard the effect that can at once use; Accordingly, after die life arrives, can by mechanism unit module integral demounting, be installed on new die, the initial length that only need adjust corresponding type pin 7 can come into operation, and reaches and saves the mould manufacturing time, save manufacturing cost, the effect that green circulatory utilizes.
