Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in this utility model and the feature in embodiment can be mutually combined.
At the end of injection ratio pressure described in the present embodiment refers to stamp, slide block acts on the pressure in pressure chamber inner metal liquid unit are.
Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
The present embodiment relates to a kind of core-pulling mechanism, and its overall structure includes guide sliding base, take-up housing, drive division, sticking department and return portion.
Wherein, the take-up housing with slide block slides and is located in guide sliding base；Drive division and take-up housing are in transmission connection and can order about take-up housing and reciprocatingly slide in guide sliding base, are formed with the gap along take-up housing glide direction between the clutch end and take-up housing of drive division；Sticking department is located between take-up housing and guide sliding base, sticking department includes sliding the latch that be located on take-up housing and with drive division clutch end can be in transmission connection, and the engaging portion being located on guide sliding base, drive division order about take-up housing enter core time, one end of latch because of ordering about of drive division engaging in engaging portion；Return portion is located on take-up housing or guide sliding base, the clutch end of drive division slide along direction of loosing core and sliding through gap time, it is locking that one end of latch departs from engaging portion because of ordering about of return portion.
This core-pulling mechanism is by arranging sticking department between take-up housing and guide sliding part, take-up housing can be made to enter after core puts in place firmly locked, and by the setting in return portion, that can order about when loosing core that latch departs from engaging portion is locking, when making mechanism loose core, take-up housing is unlocked, thus the counteracting force applied when stamp can be avoided because of the injection ratio pressure within die cavity, make core-pulling mechanism rollback and the surface defects of products that causes.
Based on design as above thought, a kind of example arrangement of the core-pulling mechanism of the present embodiment is combined shown in Fig. 2 and Fig. 3 by Fig. 1, the clutch end 41 of drive division 4 connects linked block 51, slide in the first slide rail 22 that linked block 51 is arranged on take-up housing 2, latch 52 is in transmission connection on drive division 4 via linked block 51, and between linked block 51 and latch 52, it is located at driving section 511, linked block 51 is ordered about along when entering the slip of core direction at drive division 4, latch 52 accepts the driving of linked block 51 via driving section 511, and the second slide rail 23 along take-up housing 2 slides and engaging in engaging portion 11.Engaging portion 11 is the draw-in groove being formed on guide sliding base 1, and the quantity of draw-in groove is corresponding with the quantity of latch 52, be can be seen that by Fig. 1, and draw-in groove is 2.
Driving section 511 is the inclined-plane being located on latch 52 or linked block 51, and certainly, driving section 511 can also be for be located at the inclined-plane on latch 52 and linked block 51.Shown in Fig. 1 and Fig. 2, latch 52 and linked block 51 are provided with inclined-plane, latch 52 and linked block 51 and are connected via inclined-plane abutting.For making latch 52 stronger engaging in draw-in groove, as shown in Figure 4, take-up housing 2 is provided with linked block 51 one end can be made along entering the holding tank 25 that core direction embeds, what i.e. latch 52 accepted linked block 51 orders about engaging in after in draw-in groove, and linked block 51 can continue under the ordering about of drive division 4 in entrance holding tank 25.Affecting locking effect for avoiding foreign material to fall into, be provided with the covering plate 24 hiding the sticking department on take-up housing 2 in take-up housing 2, wherein covering plate 24 is provided with the first cavity 241 making linked block pass and the second cavity 242 making latch 52 pass.
Combined shown in Fig. 5 by Fig. 1, on take-up housing 2, the one end close to drive division 4 is formed with buckling groove 21, and the clutch end 41 at drive division 4 is provided with and slides the drive block 411 being flush-mounted in buckling groove 21 and be formed with aforesaid gap H1 between drive block 411 and buckling groove 21 inwall.Now buckling groove 21 is communicated in contiguous block 6, is provided with chute 61 at take-up housing 2 end surface, and the radial dimension of chute 61 is less than drive block 411, and the clutch end 41 of drive division 4 slides and is embedded in chute 61.In the present embodiment, drive division 4 is cylinder, and certainly, except cylinder, drive division 4 can also be hydraulic cylinder.
In the present embodiment, return portion be located in take-up housing 2 or engaging portion 11 latch 52 can be applied elastic top thrust, so that the elastic parts that latch 52 departs from engaging portion 11.For making simple in construction, elastic parts can be to be located at the spring in engaging portion 11 or other have resilient elastic component, and elastic parts can be also that one end is connected on take-up housing 2, the other end is connected to the spring of latch 52 or other resilient elastic components of tool.
The pulled core structure of the present embodiment is in use, when entering core, the clutch end 41 of drive division 4 orders about take-up housing 2 and slides, first slide rail 22 along take-up housing 2 of the linked block on drive division 4 clutch end 41 that is in transmission connection slides, and two latch 52 accept the driving of linked block and engaging in the draw-in groove on guide sliding base 1 under the effect on inclined-plane.Then the clutch end 41 of drive division 4 can order about linked block and continues to slide in holding tank 25, completes the locking of core-pulling mechanism.When loosing core, drive division 4 first drive linked block cunning through gap H1, make latch 52 depart under the effect in return portion with draw-in groove locking after, take-up housing 2 can complete to loose core under the drive of drive division 4.
Additionally, in the present embodiment as it is shown in figure 5, in engaging portion 11 side close to drive division 4 be formed with engaging portion inclined-plane 111, corresponding to engaging portion inclined-plane 111, the opposite side of engaging portion 11 is also configured to inclined-plane.When loosing core, if not arranging the elastic components such as spring as above in engaging portion 11 or between take-up housing and latch, when contiguous block 51 is driven downslide after the H1 of gap by drive division 4, under the pulling on of drive division 4, or in die cavity under the active force of swollen the be applied to take-up housing of type power 2, latch 52 is positioned at one end of engaging portion 11 can put on 111 1, the engaging portion inclined-plane active force along linked block 51 moving direction, corresponding engaging portion inclined-plane 111 also can give latch 52 1 reverse active forces, this reverse active force can produce one make latch 52 by engaging portion 11 abjection component, thus can be under the effect that swollen type power or drive division 4 persistently pull in die cavity, latch 52 is made to be repositioned in take-up housing 2 by engaging portion 11.
Therefore, except return portion as above can be in addition to elastic parts, this return portion is alternatively formed in engaging portion 11 the engaging portion inclined-plane 111 close to drive division 4 side, and employing is arranged at the elastic parts in engaging portion 11 and also may be used in engaging portion inclined-plane 111 of course simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
