Description
Technical field
It the utility model is related to a kind of bottle cap mold Pneumatic ejection structure.
Background technology
The demoulding refers to the process of deviate from product out of mould, after the completion of bottle cap injection molding, it is necessary to by bottle cap product from mould
Deviate from tool, currently used mode is to be ejected product using the center of push rod alignment bottle cap.However, for caping have it is special
It is required that can not center ejection bottle cap, pneumatic stripping means can only be used.Traditional, pneumatic demoulding mould is complicated, thickness compared with
Thickness, cost of manufacture are higher.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of bottle cap mold Pneumatic ejection structure,
Pneumatic demolding structure is simplified, reduces mold thickness, reduces die cost.
The purpose of this utility model is achieved through the following technical solutions：A kind of bottle cap mold Pneumatic ejection structure,
Including interior core, thread core, bushing, push pedal and pushing sleeve, interior core is arranged on interior core fixing plate, and thread core is arranged on
In thread core fixed plate, bushing is arranged in bushing fixed plate, and pushing sleeve is arranged in push pedal, and bottle cap formed product is in screw-type
The end of core, and it is installed on the top of pushing sleeve；
Described interior core is provided with air admission hole, and inner mold in-core is provided with the air flue connected with air admission hole, the end of interior core
Venthole is provided between mold insert, venthole connects with air flue, and the inwall of thread core goes out provided with what is be engaged with venthole
Air drain；Under matched moulds state, mold insert is overlapping with the inwall of thread core to realize sealing；After mobile thread core, mold insert and screw-type
The inwall of core staggers so that forming outlet gap between outgassing groove and bottle cap product inwall, and gases at high pressure enter from air admission hole, according to
The secondary inner side that bottle cap product is headed into by air flue, venthole, outgassing groove and outlet gap.
Described mold insert is beryllium copper insert.
The beneficial effects of the utility model are：
1）There is particular/special requirement can not realize the bottle cap product that center ejects suitable for caping, compared with traditional moulds, this knot
Structure ejecting mechanism is few, reduces template number, has effectively simplified mould structure, reduce mold thickness, also correspondingly reduces mould
Has manufacturing cost.
2）Pneumatic demolding structure is simple, and ingenious in design, product can be smooth under the double action of pushing sleeve and gases at high pressure
Simultaneously break away from moulds is ejected, stripping result is good, is favorably improved product quality.

Embodiment
The technical solution of the utility model, but the scope of protection of the utility model are described in further detail below in conjunction with the accompanying drawings
It is not limited to as described below.
As depicted in figs. 1 and 2, a kind of bottle cap mold Pneumatic ejection structure, including interior core 7, thread core 8, bushing 10,
Push pedal 4 and pushing sleeve 5, interior core 7 are arranged on interior core fixing plate 1, and thread core 8 is arranged in thread core fixed plate 2, lining
Set 10 is arranged in bushing fixed plate 3, and pushing sleeve 5 is arranged in push pedal 4, and bottle cap product 6 takes shape in the end of thread core 8, and
It is installed on the top of pushing sleeve 5；
Described interior core 7 is provided with air admission hole 9, and the air flue 11 connected with air admission hole 9 is provided with interior core 7.Such as Fig. 3 and
Shown in Fig. 4, venthole 13 is provided between the end of interior core 7 and mold insert 12, venthole 13 connects with air flue 11, thread core 8
Inwall be provided with the outgassing groove 14 that is engaged with venthole 13；Described mold insert 12 uses beryllium copper insert, can improve cooling effect
Rate, shorten the formed product cycle, improve production efficiency.Under matched moulds state, mold insert 12 is overlapping with the inwall of thread core 8 realize it is close
Envelope；After mobile thread core 8, the inwall of mold insert 12 and thread core 8 staggers so that between outgassing groove 14 and the inwall of bottle cap product 6
Outlet gap 15 is formed, gases at high pressure enter from air admission hole 9, pass sequentially through between air flue 11, venthole 13, outgassing groove 14 and outlet
Gap 15 heads into the inner side of bottle cap product 6.
It is of the present utility model as follows using process：When in matched moulds state（As shown in Figure 1）, the completion note of bottle cap product 6
Type is moulded into, because mold insert 12 is overlapping with the inwall of thread core 8（As shown in Figure 3）, it is achieved thereby that excellent sealing, from air admission hole
9 gases at high pressure being passed through can not be applied to bottle cap product 6, not interfere with the shaping of bottle cap product 6.Initially entered after mould die sinking
Into figure, a segment distance is moved on right side together for ejection state, thread core fixed plate 2 and push pedal 4, so as to drive screw-type respectively
Core 8 and pushing sleeve 5 move right respective distance, and now thread core 8 and interior core 7 stagger（As shown in Figure 2）, mold insert 12 and screw thread
The inwall of core 8 staggers so that forming outlet gap 15 between outgassing groove 14 and the inwall of bottle cap product 6（As shown in Figure 4）, high pressure
Gas passes sequentially through air admission hole 9, air flue 11, venthole 13, outgassing groove 14 and outlet gap 15 and smoothly enters interiors of products, when complete
Rear thread core 8 is acted more than not continue to move, and pushing sleeve 5 continues to move, in the collective effect of pushing sleeve 5 and gases at high pressure
Under, bottle cap product 6 smoothly ejects and break away from moulds.
The utility model is applied to the bottle cap product that caping has particular/special requirement can not realize center ejection, with traditional moulds phase
Than this structure ejecting mechanism is few, reduces template number, has effectively simplified mould structure, reduces mold thickness, also corresponding drop
Low die manufacturing cost.
Described above is only preferred embodiment of the present utility model, it should be understood that the utility model is not limited to herein
Disclosed form, the exclusion to other embodiment is not to be taken as, and can be used for various other combinations, modification and environment, and
