Mold insert supporting block is cooperatively connected, and one end of cover half mold insert and insert in mold insert adjustable plate is to set reeded inclined-plane, with
Mold insert guide rail closely connects, and the other end of cover half mold insert and insert is fitted to each other to form mold cavity, and cast gate is cut off in plate
Equipped with cast gate device for excising, cast gate device for excising and mold insert guide rail cooperate the ever-increasing melt multiple injection of finishing type chamber thickness
Molding.
The driving device that mold insert position is adjusted is servo electric jar or servo-cylinder.
Mold insert adjustable plate indirectly controls the size of mold cavity by the surface rail of mold insert bottom.
Cast gate device for excising is driven by external oil cylinder.
Injection flow passage uses needle valve type hot runner.
Product is using edge side gate into glue, and multiple in mold shares runner and cast gate into glue.
The present invention has the advantage that and beneficial effect, and mold proposed by the invention is led using the mold insert of external drive mold
Rail completion indirectly controls mold cavity change in size, and mold can cut off single melt single injection using cast gate device for excising
Cold cast gate guarantees that runner is unimpeded when injecting next time, and mold insert guide rail is matched with cast gate device for excising, can complete single melt
Multiple injection molding, realize the precision size control of ultra-thick or Varying-thickness product.One kind provided by the invention is single
The precision die of melt multiple injection can effectively realize the melt filling of ultra-thick or Varying-thickness sophisticated product and close
Realification process is conducive to the development and exploitation of related new product, and without using multicolor injection machine, mould structure is simple, saves
Equipment and mold cost realizes precision and the automation control of forming process and product, suitable for multi-varieties and small-batch
Production.

Specific embodiment
1~Fig. 4 and the present invention is further elaborated by specific embodiment with reference to the accompanying drawing, wherein embodiment has
Characteristic is described, is not restrictive, this does not limit the scope of protection of the present invention.
Fig. 1 be precision die proposed by the invention overall schematic, as shown in Figure 1, precision die from top to bottom according to
Secondary to consist of the following parts: positioning ring 1, cover half hot runner manifold 3, cover half support plate 4, cover half mold insert adjustable plate 7, pours solid plate 2
Mouth excision plate 8, insert adjustable plate 9, dynamic model support plate 10, thimble 11, liftout plate 12, dynamic model backboard 13, mold insert position tune
It saves servoBcylinder 5 and cast gate cuts off hydraulic cylinder 6.The present embodiment pays close attention to single melt multiple injection function involved in precision die
The part of realization is omitted and is associated with untight other parts with the present invention.In cover half support plate 4 and dynamic model support plate 10 respectively
ServoBcylinder 5 is adjusted equipped with mold insert position, servoBcylinder 5 is connected by connecting rod with mold insert guide rail 15, and mold insert guide rail 15 is by opening up
Groove and mold insert supporting block 14 be cooperatively connected, mold insert supporting block 14 is separately fixed at cover half support plate 4 and dynamic model by screw
In support plate 10, one end of cover half mold insert 16 and insert 17 is to set reeded inclined-plane, is closely connect with mold insert guide rail 15,
The other end is fitted to each other to form mold cavity 18.Core pulling action is completed in the driving of servoBcylinder 5, directly controls cover half mold insert and dynamic model edge
Part is mobile, and the change in size for completing mold cavity thickness indirectly is controllable.Meanwhile cast gate is equipped at near-thermal Channels 20 and is cut off
Device 19 provides driving force by cast gate excision hydraulic cylinder 6.
After mold closure, mold insert position adjusts servoBcylinder 5 and ejects, and driving mold insert guide rail 15 is mobile, while with active and inactive mold
Mold insert 16 and insert 17 move separately or together, can adjust 18 thickness of mold cavity to certain value T1, are filled by injection
It fills out and the cooling molding for completing T1 product of pressure maintaining, starting cast gate device for excising 19 cuts off the cast gate of T1 product.Then, servoBcylinder 5
It retracts, drives mold insert guide rail 15, cover half mold insert 16 and insert 17 mobile, single side or two-sided 18 thickness of dilatation mold type chamber
To certain value T2, cut by second of injection molding process and the cooling molding for completing T2 product of pressure maintaining, starting cast gate device for excising 19
Except the cast gate of T2 product.And so on, T3, T4, T5 may be implemented ... and waits a series of injection moulding of thickness products.
By the inclined-plane cooperation between mold insert guide rail 15 and cover half mold insert 16 and insert 17, so that mold insert guide rail 15 exists
It will drive mold insert 16 in moving process and mold insert 17 move up and down, and then realize the big minor adjustment of 18 thickness of mold cavity, meet
Single melt multiple injection forms the requirement changed to cavity dimension.Since the movement of mold insert guide rail 15 is driven by servoBcylinder 5
Control, and the accurate control of 0.01mm can be achieved in servoBcylinder in position precision, is further ensured that 18 thickness direction of mold cavity
Accurate dimension.Meanwhile the side gate between hot-runner nozzle 20 and mold cavity 18 is the logical of melt injection molding process
Road is arranged the cast gate device for excising 19 driven by hydraulic cylinder 6, previous cast gate is cut off, it is ensured that logical when injecting next time
Road is unimpeded.
Basic structure of the invention, working principle and main advantage has been shown and described above.Need exist for it is clear that,
Although the present invention has been described in detail, it but for the related personnel of the industry, makes on the basis of the present invention
Any similar modification all should belong to protection scope of the present invention.
