Abstract

Ejecting mechanism and its injection mold are directly pushed up the invention provides a kind of spring, including straight jacking block, directly push up spring, straight top pull bar, core mold insert, thimble panel, thimble push plate, die shoe plate, cushion block, guide pillar, moving platen, solid plate, die cavity mold insert;A kind of spring of the invention provided using above-mentioned technical proposal directly pushes up ejecting mechanism and its injection mold, solve in cup handle product molds injection molding process, the deeper position of bone is carried on product and position of bone area is larger, the produce reality problem such as easy capping when common thimble pushing method ejects;It is reasonable in design, compact-sized, working stability, securely and reliably.

Description

A kind of spring directly pushes up ejecting mechanism and its injection mold
Technical field
The present invention relates to injection mold mechanism design field, specially a kind of spring directly pushes up ejecting mechanism and its injection mould Tool.
Background technology
During the ejection of molded product, with the deeper position of bone and larger, the common thimble top of position of bone area in product design Go out mode and be difficult to ejecting function, product is easily by capping, thus it is big to design ejecting force, when and can ensures product ejection not The ejecting mechanism of deformation.
The content of the invention
The technical problems to be solved by the invention are that providing a kind of spring directly pushes up ejecting mechanism and its injection mold, design Rationally, compact-sized, working stability is securely and reliably, easy-to-use;To solve above-mentioned existing technical problem, the present invention uses Following scheme:A kind of spring directly pushes up ejecting mechanism and its injection mold, including straight jacking block, directly pushes up spring, straight top pull bar, core edge Part, thimble panel, thimble push plate, die shoe plate, cushion block, guide pillar, moving platen, solid plate, die cavity mold insert.
Preferably, the straight top component includes straight jacking block, directly pushes up spring, straight top pull bar;The straight jacking block upper end be into Type face, periphery while with it is gradient for ° hypotenuse, its excess-three side is straight body face;There is straight top straight jacking block lower end by spiral marking connection Pull bar, straight top pull bar bottom are provided with screw head, and screw head is hidden in corresponding to thimble push plate in location hole, and its lower end is quiet in mould Distance H during state installment state apart from die shoe plate is mm;Straight top spring is installed on the correspondence position circular hole that moving platen is opened up In groove, and it is placed on straight top pull bar, straight jacking block lower surface is close in its upper end, straight to push up spring at work all the time in compression shape State;Straight top pull bar on mould when installing through the hole set by correspondence position on thimble panel;Directly top pull bar main function is Ensure the reliable reset of straight jacking block.
Preferably, the mould structure composition includes core mold insert, thimble panel, thimble push plate, die shoe plate, pad Block, guide pillar, moving platen, solid plate, die cavity mold insert.
Beneficial effect:A kind of spring that the present invention is provided using above-mentioned technical proposal directly pushes up ejecting mechanism and its injection mould Tool, solve in cup handle product molds injection molding process, carry the deeper position of bone on product and position of bone area is larger, common The produce reality problem such as easy capping when thimble pushing method ejects;It is reasonable in design, it is compact-sized, working stability, safely may be used Lean on.
Brief description of the drawings
Fig. 1 directly pushes up ejecting mechanism and its injection mold application ejecting mechanism and its mould structure by a kind of spring of the present invention Schematic diagram.
Embodiment
Fig. 1 show related description figure of the present invention;A kind of spring directly pushes up ejecting mechanism and its injection mold, including straight jacking block 1st, directly top spring 2, straight top pull bar 3, core mold insert 4, thimble panel 5, thimble push plate 6, die shoe plate 7, cushion block 8, guide pillar 9, dynamic Template 10, solid plate 11, die cavity mold insert 12.
A kind of spring directly pushes up ejecting mechanism and its injection mold, and the straight top component includes straight jacking block 1, directly pushes up spring 2, be straight Top pull bar 3;The straight upper end of jacking block 1 is forming surface, while with the gradient hypotenuse for being 2 °, its excess-three side is straight body face on periphery; There is straight top pull bar 3 the straight lower end of jacking block 1 by spiral marking connection, and the straight bottom of top pull bar 3 is provided with screw head, and screw head is hidden in thimble and pushed away Corresponding to plate 6 in location hole, its lower end is 23mm apart from the distance H of die shoe plate in mould static state installment state;Straight top bullet Spring 2 is installed in the correspondence position circle hole groove that moving platen 10 is opened up, and is placed on straight top pull bar 3, and straight jacking block 1 is close in its upper end Lower surface, the straight spring 2 that pushes up are in compressive state all the time at work;Straight top pull bar 3 passes through thimble panel 5 when being installed on mould Hole set by upper correspondence position;The straight main function of top pull bar 3 is to ensure that the reliable reset of straight jacking block 1.
Mould structure composition includes core mold insert 4, thimble panel 5, thimble push plate 6, die shoe plate 7, cushion block 8, led Post 9, moving platen 10, solid plate 11, die cavity mold insert 12.
During real work, as shown in figure 1, its motion operation principle is as follows:
1) Injection Motor Template pulls mould dynamic model part to retreat when molding, and mould goes out to open in die joint, works as injection machine When push rod withstands the ejection of thimble push plate 6, as thimble push plate 6 and thimble panel 5 loosen to the straight tightening force of top pull bar 3, straight top The compression stress of spring 2 is released, and the straight spring 2 that pushes up releases straight jacking block 1 from core mold insert 4, so as to auxiliary mould ejector Structure ejects product;
2) when resetting, thimble push plate 6 and thimble panel 5 are pushed back reset by mould ejection resetting-mechanism, so as to thimble panel 5 Straight jacking block 1 is retracted by reset by straight top pull bar 3, screw head lower end in mould static state installment state apart from die shoe plate away from From H be 23mm to reset when have enough adjustment spaces, mould closure, wait the beginning of next injection cycle.
Specific embodiment described herein is only the technology neck belonging to the present invention to spirit explanation for example of the invention The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode Generation, but without departing from the spiritual of the present invention or surmount scope defined in appended claims.
