Embodiment one:
It please refers to Fig.1 to Fig.3, is a kind of ejecting mechanism provided in this embodiment, comprising: mode 1, die core insert 2, first
Mandril 3 and multiple second mandrils 4.Die core insert 2, the first mandril 3 and multiple second mandrils 4 are arranged in mode 1, the
One mandril 3 is fixedly connected with die core insert 2, and the first mandril 3 pushes die core insert 2 vertically moving, makes die core insert 2 can
It is stretched out from the bottom surface of mode 1, multiple second mandrils 4 are vertically moving and can stretch out from the bottom surface of mode 1, die core insert 2
It is jointly mobile to eject the product 100 for ejecting station that ejecting mechanism bottom surface is arranged in multiple second mandrils 4.It needs to illustrate
Ground, the area of the bottom face of die core insert 2 here are greater than the area of the bottom face of the second mandril 4.
The present embodiment passes through the collective effect ejecting product of die core insert 2 and multiple second mandrils 4, is being ejected product
During can uniform force, solve and mandril is used only in the prior art ejects product, make what product was easily deformed to ask
Topic, improves the yield rate of product and the quality of product, improves production efficiency.
In addition, the ejecting mechanism further include: the first power output source (not shown) and the second power output source are (in figure
It is not shown).First power output source controls the first mandril 3 and pushes die core insert 2 vertically moving, the second power output source
It is vertically moving to control multiple second mandrils 4.It should be understood that can be a second power output source here passes through biography
It is vertically moving that dynamic component controls multiple second mandrils 4 simultaneously, is also possible to multiple second power outputs source, each power
It is vertically moving that output source controls second mandril 4.
Embodiment two:
Referring still to Fig. 1 to Fig. 3, what is different from the first embodiment is that mode 1 specifically includes: the first mode 11 and the second mode
12.The top of the second mode 12 is arranged in first mode 11, and the bottom surface of the first mode 11 is connect with the top surface of the second mode 12, the
One mandril 3 is set in the first mode 11, and die core insert 2 is set in the second mode 12.First mandril 3 pushes die core insert 2
It is vertically moving, it stretch out die core insert 2 can from the bottom surface of the second mode 12, multiple second mandrils 4 are transported along the vertical direction
It moves and can be stretched out from the bottom surface of the second mode 12, die core insert 2 and multiple second mandrils 4 are jointly mobile to eject setting second
The product 100 of the ejection station of 12 bottom surface of mode.Die core insert 2 is equipped with retention bead 21, is equipped with and limit in the second mode 12
The limit concave surface 121 of 21 cooperation of position protrusion, retention bead 21 and limit concave surface 121 cooperation limitation die core insert 2 stretch out the second mould
The outreach of benevolence 12.
In the present embodiment, the ejection process of product is divided into two stages, in the first phase, die core insert 2 and multiple
Second mandril, 4 collective effect is on product, which is the initial stage of ejection process, and product is tighter in conjunction with mold, needs
Biggish power carrys out ejecting product, therefore product is easiest to that deformation occurs in this stage, passes through die core insert 2 and multiple second tops
The collective effect of bar 4, make product at this stage can uniform force, reduce the probability of deformation of products；In second stage, mode
Mold insert 2 due to retention bead 21 with limit concave surface 121 common position-limiting action and halt, multiple second mandrils 4 continue to make
With on product, product is separated and ejected with mode and die core insert.
Die core insert 2 is located at the middle part of the second mode 12, and the first mandril 3 is connect through the first mode 11 with die core insert 2,
Multiple second mandrils 4 are uniformly distributed around die core insert 2, and multiple second mandrils 4 run through the first mode 11 and the second mode 12.
Since the area of the bottom face of die core insert 2 is greater than the area of the bottom face of the second mandril 4, and by die core insert 2
The middle part of second mode 12 is set, multiple second mandrils 4 are uniformly distributed around die core insert 2, in die core insert 2 and multiple
During the collective effect ejecting product of second mandril 4, the stress of product can be more uniform, reduces the possibility of deformation of products
Property.
Embodiment three:
What is different from the first embodiment is that the ejecting mechanism further include: controller (not shown) and sensor are (in figure not
Show), controller is electrically connected with sensor, the first output power source and the second output power source respectively.Sensor is arranged at this
It ejects near station, whether has product on the ejection station for detecting, when sensor, which detects, has product on ejection station
Controller is then signaled to, controller controls the first output power source and the second output power source ejecting product.
Above-described is only embodiments of the present invention, it should be noted here that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, improvement can also be made, but these belong to protection model of the invention
It encloses.
