Abstract

The invention provides a double-layer ejector structured mould frame. The double-layer ejector structured mould frame comprises an upper heat insulation board, an upper mould base board, an upper supporting board, an upper cushion board, a mould cavity fixing board, a mould core fixing board, a movable mould cushion board, an upper cushion block, an upper ejector pin cover board, an upper ejector pin pushing board, a special mechanism mounting board, a lower cushion board, a lower cushion block, a lower ejector pin cover board, a lower ejector pin pushing board, a lower mould base board, a lower pushing board garbage pin, a middle pushing board, an upper pushing board garbage pin, a return rod, a pushing board guide post, a mould cavity guide post and a hot runner board. According to the mould frame provided by adopting the technical scheme, when a product is ejected, a mould core is arranged inside an ejector mechanism pushing tube in a sliding manner, and a pushing board is arranged inside the mould core in a sleeving manner, and the pushing rod and the pushing tube are required to be pushed out synchronously, the product ejection and the automatic mould plastic production can be realized by a simple mechanism, so that the product molding quality is effectively guaranteed, the mould frame is reasonable in structural design, compact in structure, safe and reliable, and convenient to use and can work stably.

Description

A kind of double-deck ejecting structure mould bases

Technical field

The present invention relates to injection mold mechanism design field, be specially a kind of double-deck ejecting structure mould bases.

Background technology

Generally, when plastic products have ejector sleeve to release, generally that the push rod that product releases ejector sleeve center then maintains static by ejector sleeve, but, if cover has core inside ejector sleeve, and when cover has a push rod inside core, and when needing push rod and ejector sleeve simultaneous ejection, need to design special ejecting mechanism and produce with the automation injection moulding completing product.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of double-deck ejecting structure mould bases, reasonable in design, compact conformation, and working stability is safe and reliable, easy-to-use; For solving above-mentioned existing technical problem, the present invention adopts following scheme: a kind of double-deck ejecting structure mould bases, comprises that 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 cover plate, lower thimble push plate, counterdie seat board, lower push pedal rubbish are fixed, intermediate push rod, upper push pedal rubbish nail, release link, push pedal guide pillar, die cavity guide pillar, hot runner manifold.

As preferably, the double-deck ejecting mechanism of described mould bases comprises that thimble cover plate, upper thimble push plate, lower thimble cover plate, lower thimble push plate, lower push pedal rubbish are fixed, intermediate push rod, upper push pedal rubbish nail, release link, push pedal guide pillar; Described upper thimble cover plate, upper thimble push plate composition ejecting mechanism ground floor top board, lower thimble cover plate, lower thimble push plate composition ejecting mechanism second laminate, the first laminate, the second laminate are connect by intermediate push rod; Release link is installed on the first laminate plate, for first, second two-layer liftout plate provides reset power; Push pedal guide pillar provides motion guide for first, second two-layer liftout plate.

Beneficial effect: the double-deck ejecting structure mould bases of the one that the present invention adopts technique scheme to provide, when product ejects, inside its ejecting mechanism ejector sleeve, cover has core, and when inside core, cover has a push rod, and when needing push rod and ejector sleeve simultaneous ejection, can eject with the product that simple mechanism realizes above-mentioned feature and automation molding is produced, effectively ensure that forming quality of products, die carrier structure is reasonable in design, compact conformation, working stability, safe and reliable, easy-to-use.

Detailed description of the invention

Fig. 1-4 is depicted as related description figure of the present invention; A kind of double-deck ejecting structure mould bases, comprises that thermal insulation board 1, upper clamping plate 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, counterdie seat board 16, lower push pedal rubbish are fixed 17, intermediate push rod 18, upper push pedal rubbish nail 19, release link 20, push pedal guide pillar 21, die cavity guide pillar 22, hot runner manifold 23.

The double-deck ejecting mechanism of described mould bases comprises that thimble cover plate 9, upper thimble push plate 10, lower thimble cover plate 14, lower thimble push plate 15, lower push pedal rubbish are fixed 17, intermediate push rod 18, upper push pedal rubbish nail 19, release link 20, push pedal guide pillar 21; Described upper thimble cover plate 9, upper thimble push plate 10 form ejecting mechanism ground floor top board, and lower thimble cover plate 14, lower thimble push plate 15 form ejecting mechanism second laminate, and the first laminate, the second laminate are connect by intermediate push rod 18; Release link 20 is installed on the first laminate plate, for first, second two-layer liftout plate provides reset power; Push pedal guide pillar 21 provides motion guide for first, second two-layer liftout plate.

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, thus lower thimble push plate 15 is motionless with push rod, simultaneously, lower thimble push plate 15 also will withstand upper thimble push plate 10 by withstanding intermediate push rod 18, thus upper thimble push plate 10 is motionless with ejector sleeve, thus, the object that ejector sleeve and central pusher eject simultaneously is reached, as shown in Figure 4.

Specific embodiment described herein is only to the explanation for example of the present invention's spirit, those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
