Abstract

The invention provides a multilayer eject-out structure injection molding mold. The multilayer eject-out structure injection molding mold comprises an upper heat insulating plate, an upper mold base plate, an upper supporting plate, an upper cushion plate, a mold cavity fixing plate, a mold core fixing plate, a movable mold cushion plate, an upper cushion block, an upper ejecting pin cover plate, an upper ejecting pin push plate, a special mechanism installing plate, a lower cushion plate, a lower cushion block, a lower ejecting pin cover plate, a lower ejecting pin push plate, a lower mold base plate, a lower push plate trash nail, a middle push rod, an upper push plate trash nail, a resetting rod, a push plate guiding column, a mold cavity guiding column and a hot runner plate. By adopting a mold frame of the multilayer eject-out structure injection molding mold provided by the above technical scheme, when a product is ejected out, the interior of an eject-out mechanism push pipe of the product is sleeved with a mold core, the interior of the mold core is sleeved with a push rod and it is needed to push out the push rod and the push pipe at the same time, eject-out and automatic molding production of the product in the above characteristics can be achieved through a simple mechanism, the product forming quality is effectively guaranteed, and the mold frame is reasonable in structural design, compact in structure, stable in work, safe, reliable and convenient to use.

Description

Multilayer ejecting structure injection mold
Technical field
The present invention relates to injection mold mechanism design field, specially multilayer ejecting structure injection mold.
Background technology
Typically, when plastic products have ejector sleeve to release, usually ejector sleeve releases product and the push rod at ejector sleeve center is then fixed It is motionless, but, if ejector sleeve the inside is cased with core, and when being cased with push rod inside core, and need push rod and ejector sleeve is same When step is released, the automation for designing special ejecting mechanism to complete product is needed to be molded production.
The content of the invention
The technical problem to be solved is to provide multilayer ejecting structure injection mold, and reasonable in design, structure is tight Gather, working stability is safe and reliable, easy-to-use;To solve above-mentioned existing technical problem, the present invention adopts following scheme:It is many Layer ejecting structure injection mold, including upper thermal insulation board, upper clamping plate, upper supporting plate, upper padding plate, impression bolster, core fixing plate, Dynamic model backing plate, upper cushion block, upper thimble cover plate, upper thimble push plate, special entity installing plate, lower bolster, lower cushion block, lower thimble lid Plate, lower thimble push plate, die shoe plate, lower push pedal rubbish are fixed, intermediate push rod, upper push pedal rubbish nail, release link, push pedal guide pillar, mould Chamber guide pillar, hot runner manifold.
Preferably, mould bases bilayer ejecting mechanism include upper thimble cover plate, upper thimble push plate, lower thimble cover plate, under Thimble push plate, lower push pedal rubbish are fixed, intermediate push rod, upper push pedal rubbish nail, release link, push pedal guide pillar;The upper thimble cover plate, on Thimble push plate composition ejecting mechanism ground floor top board, lower thimble cover plate, the lower thimble push plate composition laminate of ejecting mechanism second, first Laminate, the second laminate are coupled by intermediate push rod;Release link is installed on the first laminate plate, is first, second two-layer liftout plate Reset power is provided;Push pedal guide pillar provides motion guide for first, second two-layer liftout plate.
Beneficial effect:The multilayer ejecting structure injection mold that the present invention is provided using above-mentioned technical proposal, in product ejection When, its ejecting mechanism ejector sleeve the inside is cased with core, and when being cased with push rod inside core, and need push rod and ejector sleeve synchronization During release, the product ejection of features described above can be realized with simple mechanism and molding production is automated, be effectively guaranteed product Forming Quality, die carrier structure is reasonable in design, compact conformation, and working stability is safe and reliable, easy-to-use.

Specific embodiment
Fig. 1-4 show related description figure of the present invention;Multilayer ejecting structure injection mold, including upper thermal insulation board 1, upper mould Seat board 2, upper supporting plate 3, upper padding plate 4, impression bolster 5, core fixing plate 6, dynamic model backing plate 7, upper cushion block 8, upper thimble cover plate 9, Upper thimble push plate 10, special entity installing plate 11, lower bolster 12, lower cushion block 13, lower thimble cover plate 14, lower thimble push plate 15, under Die holder plate 16, lower push pedal rubbish are determined 17, intermediate push rod 18, upper push pedal rubbish nail 19, release link 20, push pedal guide pillar 21, die cavity and are led Post 22, hot runner manifold 23.
The mould bases bilayer ejecting mechanism includes upper thimble cover plate 9, upper thimble push plate 10, lower thimble cover plate 14, lower thimble 17, intermediate push rod 18, upper push pedal rubbish nail 19, release link 20, push pedal guide pillar 21 are determined in push pedal 15, lower push pedal rubbish;The upper top Needle cover plate 9, the composition ejecting mechanism ground floor top board of upper thimble push plate 10, lower thimble cover plate 14, lower thimble push plate 15 composition ejection The laminate of mechanism second, the first laminate, the second laminate are coupled by intermediate push rod 18;Release link 20 is installed on the first laminate plate, Reset power is provided for first, second two-layer liftout plate;Push pedal guide pillar 21 provides motion and leads for first, second two-layer liftout plate To.
During real work, as shown in Figure 3, Figure 4, its motion operation principle is as follows:
Injection machine push rod withstands lower thimble push plate 15, so as to lower thimble push plate 15 is motionless with push rod, meanwhile, lower thimble push plate 15 Also upper thimble push plate 10 will be withstood by withstanding intermediate push rod 18, so as to upper thimble push plate 10 is motionless with ejector sleeve, thus, reach To the purpose that ejector sleeve and central pusher are ejected simultaneously, as shown in Figure 4.
Specific embodiment described herein is only explanation for example spiritual to the present invention, technology neck belonging to the present invention The technical staff in domain can be made various modifications to described specific embodiment or supplement or replaced using similar mode Generation, but without departing from the spiritual of the present invention or surmount scope defined in appended claims.
