Description
Technical field
This utility model relates to mould applications, particularly relates to a kind of independent cavity jacking mechanism.
Background technology
In the opening and closing mold process of some product, it is only bigger along local package power at cover half side.If mould does not design the pre-ejecting mechanism of cover half in the region that these package powers are bigger, after die sinking, product has viscous cover half or the serious problem of local deformation；But as the situation that this simply local package power is big, if cavity jacking uses the push rod similar with dynamic model to push away fixed plate form, cost can be higher, taking up room also can be bigger, and cover half cage plate back to hollow out a lot of space to accommodate cavity jacking mechanism, have impact on the intensity of cover half, thus affect die life.
Utility model content
In order to solve the problems referred to above, the purpose of this utility model is to provide a kind of independent cavity jacking mechanism, occupies little space and does not affect die life.
This utility model be the technical scheme is that
A kind of independent cavity jacking mechanism, including cover half and dynamic model, being provided with in described cover half can be along the release link self moved axially, the axis of described release link is perpendicular to dynamic model die joint, the front end of described release link has the compression zone abutting dynamic model die joint and the pushing part abutting product type plane, being terminated with elastomer after described release link, described elastomer is connected fixing with cover half.
As further improvement of the utility model, the rear portion of release link is the multidiameter structure that diameter is less than middle part, the outer wall at described rear portion is cased with pressing plate, described pressing plate is fixed on cover half rear end and pressing plate is provided with the hole passed for release link rear portion, described elastomer includes the spring being set in periphery, release link rear portion, one end of described spring is against pressing plate, and the other end is against the shaft shoulder of multidiameter.
As further improvement of the utility model, described spring is butterfly spring.
As further improvement of the utility model, being provided with position limiting structure in described cover half, described position limiting structure includes for stopping the limiting section that release link is deviate from from cover half front end.
As further improvement of the utility model, described release link includes that guide post and push rod, described elastomer are arranged on guide post afterbody, and described push rod is connected to guide post front end, and described compression zone and pushing part are positioned at push rod front end.
As further improvement of the utility model, described push rod being provided with backstop head, described limiting section is the confined planes that can abut with backstop head front end face.
The beneficial effects of the utility model are: this utility model is provided driving force when die sinking by elastomer, the product compressed in die cavity is ejected by the pushing part of release link, guarantee that product by cover half adhesion or does not deforms to cover half, during matched moulds, compression zone touches patch by elastomer reset with dynamic model die joint, so circulation, its overall structure is simple, and the space taking cover half is few.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is generalized section of the present utility model.
Detailed description of the invention
Upper and lower described in following example to the reference direction being intended only as in accompanying drawing, those skilled in the art can easily it is understood that upper and lower in accompanying drawing to be equivalent in a mold rear, the front of mould to.
Independent cavity jacking mechanism as shown in Figure 1, including cover half 1 and the dynamic model that coordinates with cover half 1, defines die cavity between cover half 1 and dynamic model.Dynamic model is not illustrated by accompanying drawing, but it is readily conceivable that dynamic model is positioned at below cover half 1, and can have product 8 in die cavity in the drawings.
Being provided with release link 2 and through hole in cover half 1, release link 2 overlaps with through-bore axis and vertically arranged in cover half 1.This release link 2 axially can move up and down along self in through hole.The most as depicted in figs. 1 and 2, the axis of release link 2 is perpendicular to dynamic model die joint 3, the i.e. moving direction of release link 2 and is perpendicular to dynamic model die joint 3 and parallel with the direction of dynamic model opening and closing mould.The front end of release link 2 has the compression zone 21 abutting dynamic model die joint 3 and the pushing part 22 abutting product type plane 7, is terminated with elastomer 5 after release link 2, and elastomer 5 is connected fixing with cover half 1.In shown in accompanying drawing, pushing part 22 is directly connected to product 8 surface, product 8 can be applied active force vertically downwards, compression zone 21 is oppressed by the dynamic model die joint 3 of dynamic model, and by the oppressive force upwards of dynamic model die joint 3 applying, and elastomer 5 is now in contraction state, release link 2 is applied active force vertically downwards so that pushing part 22 props up product surface.
When the die is closed, compression zone 21 is applied to upward pressure to force and moves in release link 2 by dynamic model die joint 3, and elastomer 5 shrinks；When die sinking, the elastic force that elastomer 5 stores acts on release link 2 makes it move down, thus product is ejected downwards and leaves cover half 1 by pushing part 22.
As further preferred embodiment, the top of release link 2 is the multidiameter structure that diameter is less than middle part, the outer wall on release link 2 top is socketed with pressing plate 4, pressing plate 4 is provided with the hole passed for release link 2 top in being fixed on the upper end of cover half 1 and pressing plate 4, release link 2 top can move axially in this hole.Described elastomer 5 is a spring, is set in release link 2 upper periphery, and its one end is against pressing plate 4 lower surface, and the other end is against the shaft shoulder of multidiameter.Spring provides elastic force by the deformation between the shaft shoulder and pressing plate 4.
Preferably, spring is butterfly spring, as more better than common cylindrical spring for energy-storage travelling wave tube.
As further preferred embodiment, being provided with position limiting structure in cover half 1, position limiting structure includes for stopping the limiting section that release link 2 is deviate from from cover half 1 front end.
Preferably, cover half 1 is included in the mould bases 11 of top and the core rod 12 below mould bases 11.Release link 2 includes guide post 23 and push rod 24, and elastomer 5 is arranged on guide post 23 top and is positioned at mould bases 11, and push rod 24 is connected to guide post 23 lower end, compression zone 21 and pushing part 22 and is positioned at push rod 24 front end.
Preferably, push rod 24 being provided with the body of rod and the backstop 241 on body of rod top, the diameter of this backstop 241 is more than shank diameter, and described limiting section is the confined planes 6 that can abut with backstop 241 front end face, and this confined planes 6 is formed due to a stage portion.Specifically, arranging one or more deep gouges 121 in core rod 12 upper surface, the bottom face of deep gouge 121 is provided with the perforation passed for the body of rod, defines described stage portion between deep gouge 121 and perforation, this stage portion can support limit stop 241, stops it to move down further.
The above be this utility model preferred embodiment, it is not intended that the restriction to this utility model protection domain.
