The shaping position and trip positions of block are accurately positioned.
As shown in Figure 7, Figure 8 and Figure 9, a kind of injection mold, there is the interior He of back-off 901 for side for being molded plastic product
The cylinder 9 of outer back-off 902, it includes caster, male template 4, in addition to above-mentioned outer slide adds inner slide tripping mechanism 1, outer cunning
Block 2 and outer slide drive mechanism 3, the caster docks with the male template surrounds injection molding die cavity, the caster
And the male template surrounding is fixed in institute close to the position of docking formed with the sliding block breach A5 for connecting the die cavity, the outer slide
State on outer slide seat, and the outer slide and the outer slide seat slide other direction stop in dropout direction and be slidedly arranged on the cunning
In block breach A, the outer slide drive mechanism is installed in the male template, drives the outer slide seat and the outer slide to exist
Slide in dropout direction；The male model core is in the die cavity and is installed in the male template, and the push pedal can eject
Slide other direction stop and be installed in the male template in die cavity in direction；The push pedal can be driven in ejection side by also including two
To the lengthening push rod 6 of slip.So, outer slide seat and outer slide is driven to be slided to outside center by outer slide drive mechanism, can
Realize that outer slide is threaded off with back-off on the outside of cylinder, after outer slide exits push pedal, by lengthening top rod driving push pedal upward sliding, add
While long push rod drives ejecting push plate, drive inner slide inwardly to move by pulling block, inner slide can be achieved and taken off with cylinder inner reverse fastener
Button；After inner slide is threaded off, push pedal has just contacted cylinder product bottom, and inner slide back-off has been detached from, and therefore, lengthens push rod energy
Enough push pedal is driven to continue ejecting product.That is, the utility model push pedal and the design of shifting block, are realizing what inner slide was threaded off
Meanwhile the function of ejecting product is realized, it can greatly reduce mould gross thickness, so as to greatly reduce injection machine tonnage, simultaneously
Mould also greatlys save cost, and the support block and ejector retainner plate having originally all eliminate.Inner slide is designed on the downside of outer slide, in saving
Sideslip block space, does not influence outer slide, nor affects on the spiral water route among male model core；Via design and public affairs in the middle part of push pedal
Model core coordinates, for example during cylinder during cylinder, circle of the monoblock push pedal more than 3/4 is ejecting, and ejection balance, does not have and rises capping
Phenomenon.
Preferably, referring to Fig. 8, the structure that the male model core is installed in the male template is：Male model core is the bottom of close to
End formed with lateral margin 1033, in the male template to should lateral margin formed with lateral margin groove, the lateral margin is placed in the lateral margin groove, and
It is locked to by bolt in male template, push pedal is pressed in the upside of lateral margin.So, can be right by the cooperation of lateral margin and lateral margin groove
Male model core is positioned, and can be fixed to by bolt in male template.The upside of lateral margin and the groove-bottom of positioning push pedal
Portion is concordant.
Preferably, referring to Fig. 9, male model is provided with the groove for housing the push pedal, groove and push pedal form fit, push pedal week
To stop in the groove, the male template is provided with the corresponding resigning through hole 401 for lengthening push rod, the lengthening push rod
Upper end is fixedly connected with the push pedal, and in the middle part of the lengthening push rod and lower end is actively located in the resigning through hole, described to add
Long push rod is provided with limited step 601 close to its lower end, and the limit stops of the corresponding limited step are provided with the resigning through hole
402.So, when driving lengthens push rod lower end, lengthen push rod and slided in resigning through hole, push pedal can be driven to be moved in ejection direction
It is dynamic.Limited step coordinates with limit stops, and the height of ejecting push plate is limited.During concrete application, two push rods are symmetrically set
In the relative both sides of product, to ensure ejection balance.
Preferably, referring to Fig. 2 and Figure 10, the structure that the push pedal can be slided in ejection direction is：Provided with some guide rods 7
And its corresponding guide pin bushing 8, the pilot hole 403 formed with the corresponding guide rod and guide pin bushing, the guide pin bushing lead in the male template
