Description
Technical field
The utility model relates to injection molding apparatus field, is specifically related to a kind of injection mold with female medical transfusion part product fast demoulding.
Background technology
At mould manufacturing industry, the demoulding of full automatic screw thread core pulling system is compared always and is difficult to solve, the demoulding that the depth of thread especially as medical transfusion part is comparatively large, the strength of materials is higher, accuracy of thread requires higher, small-bore product.Conventional method is generally adopt the tooth bar demoulding, and the advantages such as structure is simple although the rack machine mould emptier of the method has, technology maturation, stripping rate is slow, and production efficiency is low.
Utility model content
The utility model object is to solve the problems of the technologies described above, and provides a kind of injection mold with female medical transfusion part product fast demoulding.
In order to achieve the above object, technical solutions of the utility model are as follows:
An injection mold for screw product fast demoulding, comprise solid plate, moving platen, backing plate and at least one group of back-out mechanism, described back-out mechanism comprises ejector sleeve and driven gear, and described ejector sleeve comprises ejector sleeve cover and built-in ejector pin wherein; One end of described ejector pin is provided with external screw thread, and the other end connects described driven gear; Described driven gear under the drive of master gear by fluid motor-driven; Be provided with slidably ejector retainner plate in described backing plate, one end of described ejector sleeve cover is secured on described ejector retainner plate, and the other end abuts on product after moulding for ejecting product; Precompressed spring is provided with between described moving platen and backing plate.
Preferably, master gear described in described fluid motor-driven rotates, and described master gear drives driven gear to rotate, when described driven gear has at least two, one of them driven gear drives another driven gear by travelling gear, and turning to of all driven gears is forever consistent.
Preferably, between described moving platen and backing plate, journey stop gear is set.
Preferably, described ejector retainner plate is by injection machine top rod driving.
The beneficial effects of the utility model are mainly reflected in: transmission efficiency is higher, the demoulding is rapid, and production efficiency is high, especially the female medical transfusion part product fast demoulding of appropriate bands.

Detailed description of the invention
Carry out clear, complete description below in conjunction with accompanying drawing by the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.
As shown in Figure 1, the utility model discloses a kind of injection mold of screw product fast demoulding, comprise solid plate 1, moving platen 2, backing plate 3 and at least one group of back-out mechanism, described back-out mechanism comprises ejector sleeve 5 and driven gear 6, and described ejector sleeve 5 comprises ejector sleeve cover 51 and built-in ejector pin 52 wherein; One end of described ejector pin 52 is provided with external screw thread 53, and the other end connects described driven gear 6; Described driven gear 6 is driven by hydraulic motor 9 under the drive of master gear 8; Be provided with slidably ejector retainner plate 4 in described backing plate 3, one end of described ejector sleeve cover 51 is secured on described ejector retainner plate 4, and the other end abuts on product after moulding for ejecting product; Precompressed spring 7 is provided with between described moving platen 2 and backing plate 3.Arrange journey stop gear 10 between described moving platen 2 and backing plate 3, the journey stop gear 10 of this preferred embodiment is one and is fixed on screw on backing plate 3.Described ejector retainner plate 4 is driven by injection machine push rod 12.
In general, in order to reduce costs, certainly will have in a secondary mould and overlapping mould core & cavity more.In this preferred embodiment, there are 4 cover mould core & cavities, then must be provided with 4 groups and screw out mechanism, namely comprise 4 driven gears 6.Shown in composition graphs 3, in the present embodiment, described hydraulic motor 9 drives described master gear 8 to rotate, and described master gear 8 drives and rotates from two moving gears 6, described driven gear 6 drives another two driven gears 6 to rotate by travelling gear 11 again, and turning to of all driven gears 6 is forever consistent.Like this, by the setting of master gear 8, travelling gear 11,4 groups of back-out mechanisms can be realized and work simultaneously.
After the injection moulding of band female medical transfusion part product completes, open solid plate 1, moving platen 2, primer fluid pressure motor 9, drive master gear 8 to rotate, master gear 8 and travelling gear 11 drive the equidirectional rotation of driven gear 6 of each back-out mechanism, thus drive ejector pin 52 to rotate.As shown in Figure 2, because product 100 has two convex shoulders 101, so product 100 can not be able to be rotated by moving platen 2 restriction.Meanwhile, due to the cause of spring 7, when ejector pin 52 rotates, spring 7 lifts away from described backing plate 3 with driving moving platen 2 constant speed.When the stroke of moving platen 2 arrives the range of journey stop gear 10, described ejector pin 52 departs from completely from product 100, then the internal thread of described product 100 completes.Further, injection machine push rod 12 promotes ejector sleeve cover 51 and is released by product, thus completes the injection moulding demoulding of a collection of product.
After the product after the demoulding is removed, solid plate 1 and the 2-in-1 mould of moving platen, and Compress Spring 7 is backing plates 3 resets, and so just reaches the condition of injection moulding next time.Therefore adopt the utility model device, compared with traditional tooth bar demoulding, the demoulding is rapid, and production efficiency is high, especially the female medical transfusion part product fast demoulding of appropriate bands.
Based on embodiment of the present utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
