Description
Technical field
The present invention relates to a kind of injection mold ejecting mechanisms, more particularly to a kind of ejection that can repeatedly eject over long distances
Mechanism, especially suitable in the relevant injection mold of automobile lamp super thick light guide.
Background technique
With the development of automobile lamp industry, utilization of the super thick light guide in the following car light will be more and more common.Due to
The spherical pattern structure of the particularity of super thick light guide, super thick light guide product is especially more, in order to form spherical pattern structure, needs
Plug is set, but product cannot still demould after the ejection simultaneously of many plugs, therefore just need repeatedly ejection, correspondingly in mold
Need to use multiple ejecting mechanism.Existing multiple ejecting mechanism mainly ejecting mechanism twice, including be with spring ejection,
Or it is ejected with three template dies.But be restricted very much on stroke using spring ejection and spring poor reliability, and utilize three
Template die ejection, structure is complicated for ejecting mechanism, and die cost is high.
Summary of the invention

When ejector retainner plate backing plate be identified as ejection in place, the ejector retainner plate backing plate ejection cylinder stops, so far realizing and eject for the first time, this
The state of the multiple long range ejecting mechanism of Shi Suoshu is as shown in Figure 2.
Then, first order ejector retainner plate ejection cylinder 4 acts, and the ejector retainner plate 3 of the same level is driven to move upwardly together, until first
Grade ejector retainner plate spacing collision block touching first order ejector retainner plate ejects limit switch, and triggering first order ejector retainner plate ejection limit switch 7 is sent out
Stop signal out, first order ejector retainner plate is identified as ejection in place at this time, and first order ejector retainner plate ejection cylinder 4 stops, so far real
It now ejects for second, the state of the multiple long range ejecting mechanism described at this time is as shown in Figure 3.
When there is the multistage ejector retainner plate, at different levels to act step by step, the same first order of the course of work of every level-one.
The return process of the multiple long range ejecting mechanism is preferred are as follows: the ejector retainner plates at different levels according to from most end level-one to
The sequence of first order return one by one.First order ejector retainner plate return process is the movement of first order ejector retainner plate ejection cylinder, drives first
Grade ejector retainner plate decline, until first order ejector retainner plate spacing collision block touches first order ejector retainner plate return limit switch, triggering the
Level-one ejector retainner plate return limit switch issues stop signal, and first order ejector retainner plate ejection cylinder stops, at this time first order ejector retainner plate
Return is completed.
The ejector retainner plate revert action sequences at different levels are identical as the revert action sequence of first order ejector retainner plate.Ejector retainner plates at different levels
All after return, the movement of ejector retainner plate backing plate ejection cylinder drives the decline of ejector retainner plate backing plate, until ejector retainner plate backing plate spacing collision block is touched
Ejector retainner plate backing plate return limit switch, triggering ejector retainner plate backing plate return limit switch issue stop signal, the ejection of ejector retainner plate backing plate
Oil cylinder stops, and ejector retainner plate backing plate return is completed at this time.Whole oil cylinder returns, a circulation terminate.
Starting and stopping for the ejection cylinder of the ejector retainner plate backing plate ejection cylinder and ejector retainner plate at different levels is directly by corresponding
What the machine tool control system where mold controlled.It stops being to detect this movement with corresponding limit switch (including ejection is dynamic
Work and revert action) terminate in place as condition.
The multiple long range ejecting mechanism can also include multiple mandril (not shown)s, and one end of the mandril is solid
It is scheduled on ejector retainner plate described in afterbody, the extending direction phase of the extending direction of the mandril and the ejector retainner plate ejection cylinder
