More than the cross-sectional area in thimble portion 20, one end and the bottom needle plate 15 of fixed part 19 support, and the other end is supported with step surface 18, thimble
Stepped hole 17 is stretched out in portion 20, and coordinates with the first mode 10.15 collective effect of face needle plate 14 and bottom needle plate, fixed part 19 is fixed
In in stepped hole 17, to which the position in thimble portion 20 be fixed.
Holding part 8 is relatively set with mating surface 21 and catch surface 22.Catch surface 22 is set to mating surface 21 far from face needle plate
14 side, catch surface 22 and the side wall of bottom needle plate 15 are mutually perpendicular to, and mating surface 21 is in that default angle is arranged with mating surface 21, card
Face 22 is held for being supported with deduction 5, to be moved under the drive of deduction 5, mating surface 21 is used to coordinate with stop part 6, with
It is headed into storage tank 12 under the action of stop part 6.Specifically, the range of angle is preset between 45 degree to 65 degree, so as to
In being slidably matched for mating surface 21 and stop part 6.In the present embodiment, default angle is 55 degree, it is not limited to this, presets folder
Angle can be 45 degree, or 65 degree, the number of degrees to presetting angle are not especially limited.
In the present embodiment, deduction 5 is relatively set with supporting surface 23 and reset surface 24.It is remote that reset surface 24 is set to supporting surface 23
Side from moving platen 4, supporting surface 23 with catch surface 22 for supporting, to drive holding part 8 to be transported to close to the direction of solid plate 3
Dynamic, reset surface 24 is used to coordinate with mating surface 21, and holding part 8 is headed into storage tank 12, is convenient for the reset of deduction 5.
Please continue to refer to Fig. 2, it is notable that cavity jacking structure 1 further includes fixed plate 25, square iron 26 and reset bullet
Spring (not shown).Fixed plate 25 is set to side of the solid plate 3 far from moving platen 4, and fixed plate 25 passes through square iron 26 and solid plate 3
It is fixedly connected, the height of square iron 26 is more than face needle plate 14 and the common thickness of bottom needle plate 15, and entire ejector pin component 2 can be in fixation
Edge is moved perpendicular to the direction of die joint between plate 25 and solid plate 3.Resetting spring is set to face needle plate 14 and solid plate 3
Between, resetting spring is in compressive state always, applies the elastic force far from 3 direction of solid plate with opposite needle plate 14, to drive
Entire ejector pin component 2 resets so that bottom needle plate 15 is supported with fixed plate 25.
When producing product, moving platen 4 and solid plate 3 are molded first so that the first mode 10 and the second mode 11 close
Hold together to form the cavity of sealing, in the process, deduction 5 passes through locating part 9, and is supported with holding part 8, at this time reset surface 24 with match
Conjunction face 21 is slidably matched, and deduction 5 overcomes the elastic force of elastic component 7 to head into holding part 8 in storage tank 12, and the continuation of deduction 5 is transported forward
Dynamic, until deduction 5 is no longer supported with holding part 8, holding part 8 pop up storage tank 12 under the action of elastic component 7, supporting surface 23 and
Catch surface 22 supports；Then to molten plastic is passed through in cavity, molten plastic fills entire cavity postcooling and is molded to form product；
Then die sinking action is carried out, moving platen 4 is moved towards the direction far from solid plate 3, and in the process, deduction 5 overcomes resetting spring
Elastic force drive ejector pin component 2 to be moved towards close to the direction of solid plate 3, thimble ontology 16 stretches into the first mode 10, and by the
In one mode 10 product ejection, when ejector pin component 2 moves to predeterminated position, ejection work complete, at this time stop part 6 with match
Conjunction face 21 is slidably matched, and stop part 6 overcomes the elastic force of elastic component 7 to head into holding part 8 in storage tank 12 so that deduction 5 supports
Face 23 is held no longer to support with the catch surface of holding part 8 22, deduction 5 is detached with holding part 8, deduction 5 under the drive of moving platen 4 after
It is continuous to be moved towards the direction far from solid plate 3, it is detached from locating part 9 and stop part 6, at the same time, ejector pin component 2 is in resetting spring
It is moved to the direction far from solid plate 3 under effect, until bottom needle plate 15 is supported with fixed plate 25, stop part 6 is de- with mating surface 21
From entire cavity jacking structure 1, which is realized, to be resetted.
The side of cavity jacking structure 1 described in the embodiment of the present invention, ejector pin component 2 is provided with storage tank 12, holding part 8
It is connect with the bottom wall of storage tank 12 by elastic component 7, holding part 8 can stretch out or be retracted storage tank 12, and deduction 5 is fixedly mounted
In on moving platen 4, and with 8 clamping of holding part, moving platen 4 can be moved towards the direction far from solid plate 3, to pass through holding part 8
Ejector pin component 2 is driven to be moved to the direction close to solid plate 3, stop part 6 is fixedly installed on solid plate 3, and stop part 6 can be
Coordinate with holding part 8 when ejector pin component 2 moves to predeterminated position, to overcome the elastic force of elastic component 7 that holding part 8 is headed into storage tank
12, so that holding part 8 is detached from deduction 5.Compared with prior art, since cavity jacking structure 1 of the present invention is adopted
With with deduction 5 clamping holding part 8 and the stop part 6 that coordinates with holding part 8, so ejector pin component 2 can be realized dynamic
The case where ejecting product towards the direction of moving platen 4 from solid plate 3 under the drive of template 4, prevent product sticking to mould occurs, ejection fortune
Dynamic stability is reliable, highly practical.
