Abstract
The utility model discloses a whole-ring reversed buckle demolding mechanism. The mechanism comprises an air cylinder, a casing, a reversed buckle ring and a conical hexagonal inner core, wherein the reversed buckle ring is arranged in the casing; the conical hexagonal inner core capable of driving the reversed buckle ring to expand and contract is arranged in the reversed buckle ring; the air cylinder is connected with the conical hexagonal inner core through a connecting rod; and six T-shaped blocks are arranged on the inner side of an opening of the reversed buckle ring and used for being connected with a mold. The mechanism has the advantages and the benefits as follows: the conical hexagonal inner core is driven by the air cylinder to enable the reversed buckle ring to expand and contract, so that demolding of reversed buckles of products is realized, the products cannot be damaged during demolding, the normal production is guaranteed, and the production efficiency is high.
Description
[technical field]
The utility model relates to mould applications, especially a kind of whole circle reverse buckle demolding mechanism.
[background technology]
Mould is in industrial production, to make under external force blank become the instrument of the product that has given shape and size.Be widely used in stamping-out, die forging, cold-heading, extruding, metallic sintered products compacting, compression casting, and during the compression moulding of goods such as engineering plastics, rubber, pottery or the shaping of injection moulding process.Mould has specific profile or cavity shape, and the contour shape that application has cutting edge can make blank, by outline line shape, separated (stamping-out) occur.Application cavity shape can make blank obtain corresponding three-dimensional shape.Mould generally comprises dynamic model and two parts of cover half (or punch and die), the two partable.In the time of separately, take out product, while closing up, make blank inject mold cavity and be shaped.Mould is precision instrument, complex-shaped, bears the expansive force of blank, and structural strength, rigidity, case hardness, surface roughness and machining accuracy are all had higher requirements.
Tradition stripping means is the outside demoulding of surrounding that stripper plate promotes plastic product, the outside demoulding is forced by back-off in the inside that push rod simultaneously promotes under plastic product, and because the outer wall of inner back-off and the core inwall of inserting contacts, the inwall of inner back-off contacts with push rod outer wall, in gripping orientation, and inner back-off wall is thin, when forcing the outside demoulding, if producing, flattens inner back-off, distortion just can be deviate from, so just affect the quality of product, if inner back-off does not produce flattening, the outside demoulding is also forced in distortion, can break inner back-off, it is broken in core is inserted, product rejection so not only, also affect next injection moulding, more can cause the production efficiency of product low.
[utility model content]
The purpose of this utility model is the deficiency existing for the above prior art, when a kind of demoulding is provided, can not damage product, guarantees the whole circle reverse buckle demolding mechanism that normally carries out, enhances productivity of producing.
To achieve these goals, the utility model is achieved in that whole circle reverse buckle demolding mechanism, comprise cylinder, shell, back-off circle and cone hexagonal inner core, described back-off circle is arranged in described shell, the described cone hexagonal inner core that can drive the breathing of described back-off circle is set in described back-off circle, and described cylinder is connected with described cone hexagonal inner core by connecting rod; Opening inner side at described back-off circle arranges 6 T shape pieces, for being connected with mould; Described shell is installed on base plate, and described cone hexagonal inner core arranges locating slot and match with fixture block, and mounting spring between described fixture block and base plate limits the movable stroke of cone hexagonal inner core for fixture block being goed deep into described locating slot.By cone hexagonal inner core described in described air cylinder driven, make in described back-off circle 6 T-shaped to inside contracting, to realize the demoulding of product back-off.
At described cone hexagonal inner core, protective sleeve sealing is installed outward.
Described cylinder is installed on holder, and is realized and being fixed by limited block, spacing fixture block and fixing pin, stabilized structure, and error is little.
Between described holder and base plate, be connected with adjusting rod, described adjusting rod one end is installed on the governor motion being fixed on holder.
Described protective sleeve is connected with shell by stopping means, on described stopping means, adjusting screw(rod) is set, for adjustment cone hexagonal inner core travel range.
Prior art is compared, the advantage the utlity model has and useful technique effect are as follows: by air cylinder driven cone hexagonal inner core, make the breathing of back-off circle, realize the demoulding of product back-off, when the demoulding, can not damage product, guaranteed to produce normally carry out, production efficiency is high.

[specific embodiment]
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail to explanation.
Whole circle reverse buckle demolding mechanism, as Figure 1-4, comprise cylinder 27, shell 2, back-off circle 3 and cone hexagonal inner core 5, described back-off circle 3 is arranged in described shell 2, in the interior setting of described back-off circle 3, can drive the described cone hexagonal inner core 5 of described back-off circle 3 breathing, described cylinder 27 is connected with described cone hexagonal inner core 5 by connecting rod 24; Opening inner side at described back-off circle 3 arranges 6 T shape pieces 6, for being connected with mould.By described cylinder 27, drive described cone hexagonal inner core 5, make in described back-off circle 36 T-shaped 6 to inside contracting, to realize the demoulding of product back-off.Wherein said back-off circle 3 is spliced and forms mutually with the sub-block that described cone hexagonal inner core 5 lateral surfaces match by six medial surfaces, and T shape piece 6 is installed in every sub-block.In outer installation protective sleeve 26 sealings of described cone hexagonal inner core 5, for the protection of described cone hexagonal inner core 5, avoid getting rusty etc.Described shell 2 is installed on base plate 18, and described cone hexagonal inner core 5 arranges locating slot and matches with fixture block 16, mounting spring 22 between described fixture block 16 and base plate 18, for going deep into fixture block 16 the movable stroke that described locating slot limits cone hexagonal inner core 5.Described cylinder 27 is installed on holder 20, and is realized and being fixed by limited block 15, spacing fixture block 17 and fixing pin 14, stabilized structure, and error is little.Between described holder 20 and base plate 18, be connected with adjusting rod 25, described adjusting rod 25 one end are installed on the governor motion 28 being fixed on holder 20.Described governor motion can be adjusting screw(rod) or adjusting gear.Described protective sleeve 26 is connected with shell 2 by stopping means 23, on described stopping means 23, adjusting screw(rod) 11 is set, for adjustment cone hexagonal inner core 5 travel range.
