Description
Technical field
The utility model relates to a kind of mould, belongs to injection moulding field.
Background technology
Silica gel injection mold has been widely used among the production of silica gel product, when some silica gel product has darker glue position, in the time that product takes out, its darker glue position can produce very large pull of vacuum, when the demoulding, need larger power just can take off product, easily produce demoulding difficulty or cannot the demoulding etc. problem.
The mode that prior art often adopts manipulator gripping or thimble to eject is taken out product, because the gripping power that manipulator takes out is limited, and easily causes product to be pulled out of shape or is drawn bad.And the mode ejecting with thimble, excessive absorption affinity easily causes pushing up bad product, easily causes for a long time thimble lost efficacy or ruptured, and even occurs destroying the severe situation of mould.
Obviously, directly eject with manipulator mode or thimble the problem that does not all fundamentally solve pull of vacuum, although can take out product, but the product fraction defective taking out is high, and change thimble and need to dismantle mould, relatively taking time and effort, production efficiency is lower.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of silica gel mould structure that prevents product sticking mould that can solve pull of vacuum problem.
The utility model solves the technical scheme that its technical problem adopts:
A kind of silica gel mould structure that prevents product sticking mould, comprise rear mold jade, described rear mold jade is provided with die cavity and plunger shaft, between described plunger shaft and described die cavity, be provided with air admission hole, one air blowing mold insert is installed in described plunger shaft, and after matched moulds, the top of described air blowing mold insert seals air admission hole, and described air blowing mold insert is provided with the air intake duct being communicated with described plunger shaft, described air intake duct is connected with blower pump by air inlet pipe, and after die sinking, described air admission hole is left at the top of described air blowing mold insert.
Between the sidewall of described air blowing mold insert and the sidewall of described plunger shaft, sealing ring is installed.
The sidewall of described air blowing mold insert is provided with groove, and described sealing ring is arranged in described groove.
The bottom of described air blowing mold insert is provided with a bullet pad.
Described plunger shaft is positioned at the bottom of described rear mold jade, described air admission hole and described plunger shaft concentric.
The top of described plunger shaft and described air blowing mold insert is the taper shape that shape is identical.
The beneficial effects of the utility model are: rear mold jade of the present utility model is provided with die cavity and plunger shaft, between plunger shaft and die cavity, be provided with air admission hole, one air blowing mold insert is installed in plunger shaft, blow after the matched moulds top of mold insert seals air admission hole, after mould is opened, air admission hole is left at the top of air blowing mold insert, plunger shaft and die cavity are communicated with by air admission hole, the gas that blower pump blows out enters in die cavity, pull of vacuum in die cavity is removed, greatly reduce the absorption affinity of mould to product, not that very dark situation need not any auxiliary withdrawing device for glue position, can directly blow out product, for the dark situation in glue position, add that thimble ejects or manipulator, can be easily by product break away from moulds, can be because of the excessive deformation of products that causes of absorption affinity, damage, or damage thimble or mould.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is mould structure schematic diagram of the present utility model;
Fig. 2 is mould matched moulds view;
Fig. 3 is that mould is opened rear view.
Detailed description of the invention
With reference to Fig. 1, a kind of silica gel mould structure that prevents product sticking mould, comprise code mask 4, ejector retainner plate 3, guide plate 2 and rear pattern plate 1, between described guide plate 2 and code mask 4, push pedal 11 is installed, in described push pedal 11, be provided with pilot pin 10, on described pilot pin 10, rear mold jade 9 is installed, described rear mold jade 9 is provided with die cavity 12 and plunger shaft 13, described plunger shaft 13 is positioned at the bottom of described rear mold jade 9, between described plunger shaft 13 and described die cavity 12, be provided with air admission hole 16, one air blowing mold insert 8 is installed in described plunger shaft 13, the bottom of described air blowing mold insert 8 is provided with a bullet pad 6, described air admission hole 16 and described plunger shaft 13 concentrics, the top of described plunger shaft 13 and described air blowing mold insert 8 is the taper shape that shape is identical, blow after the matched moulds top of mold insert 8 is just in time concordant with the bottom surface of die cavity, described air blowing mold insert 8 is provided with the air intake duct 14 being communicated with described plunger shaft 13, described air intake duct 14 is connected with blower pump 5 by air inlet pipe 15.
Sealing ring 7 is installed between the sidewall of the sidewall of described air blowing mold insert 8 and described plunger shaft 13, can strengthens the effect of sealing, the sidewall of described air blowing mold insert 8 is provided with groove 17, and described sealing ring 7 is arranged in described groove 17, and mounting structure is simple, reliable.
As shown in Figure 2, when matched moulds state, described air blowing mold insert 8 relies on the elastic force of bullet pad 6 to make it tightly to fit with rear mold jade 9, and the top of air blowing mold insert 8 seals air admission hole 16.
As shown in Figure 3, after mould is opened, push pedal 11 promotes rear mold jade 9 and moves, described air admission hole 16 is left at the top of air blowing mold insert 8, plunger shaft 13 and die cavity 12 are communicated with by air admission hole 16, the gas that blower pump 5 blows out enters the air intake duct 14 of air blowing mold insert 8 by air inlet pipe 15, then enter in die cavity 12 from air admission hole 16, pull of vacuum in die cavity is removed, greatly reduce the absorption affinity of mould to product, not that very dark situation need not any auxiliary withdrawing device for glue position, can directly blow out product, for the dark situation in glue position, add that thimble ejects or manipulator, can be easily by product break away from moulds, can be because of the excessive deformation of products that causes of absorption affinity, damage, or damage thimble or mould.
