Description

The injection mold of screw product fast demoulding
Technical field
The present invention relates to injection molding apparatus field, be 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 relatively difficult to solve always, and especially the depth of thread as medical transfusion part is large, the strength of materials is higher, accuracy of thread is had relatively high expectations, the demoulding of small-bore product.Conventional method is generally to adopt the tooth bar demoulding, although advantages such as that the tooth bar machine mould emptier of the method has is simple in structure, technology maturations, stripping rate is slow, and production efficiency is low.
Summary of the invention
To the present invention seeks in order solving the problems of the technologies described above, and a kind of injection mold with female medical transfusion part product fast demoulding to be provided.
In order to achieve the above object, technical solution of the present invention is as follows:
An injection mold for screw product fast demoulding, comprises that solid plate, moving platen, backing plate and at least one group screw out mechanism, and 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; In described backing plate, be provided with slidably ejector retainner plate, one end of described ejector sleeve cover is secured on described ejector retainner plate, and the other end is connected on the product after injection mo(u)lding for ejecting product; Between described moving platen and backing plate, be provided with precompressed spring.
Preferably, master gear rotation described in described fluid motor-driven, described master gear drives driven gear rotation, in the time that 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.
Beneficial effect of the present invention is mainly reflected in: transmission efficiency is higher, the demoulding is rapid, and production efficiency is high, is especially applicable to being with female medical transfusion part product fast demoulding.

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical scheme in the embodiment of the present invention is carried out to clear, complete description, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.
As shown in Figure 1, the present invention has disclosed a kind of injection mold of screw product fast demoulding, comprise that solid plate 1, moving platen 2, backing plate 3 and at least one group screw 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; In described backing plate 3, be provided with slidably ejector retainner plate 4, one end of described ejector sleeve cover 51 is secured on described ejector retainner plate 4, and the other end is connected on the product after injection mo(u)lding for ejecting product; Between described moving platen 2 and backing plate 3, be provided with precompressed spring 7.Between described moving platen 2 and backing plate 3, journey stop gear 10 is set, the journey stop gear 10 of this preferred embodiment is a screw being fixed on backing plate 3.Described ejector retainner plate 4 is driven by injection machine push rod 12.
In general,, in order to reduce costs, in a secondary mould, certainly will have many cover mould core & cavities.In this preferred embodiment, there are 4 cover mould core & cavities, must be provided with 4 groups and screw out mechanism, comprise 4 driven gears 6.Shown in Fig. 3, in the present embodiment, described hydraulic motor 9 drives described master gear 8 to rotate, and described master gear 8 drives from two moving gears 6 and rotates, 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, can realize 4 groups of back-out mechanisms and work simultaneously.
After being with the injection moulding of female medical transfusion part product to complete, open solid plate 1, moving platen 2, primer fluid pressure motor 9, drives master gear 8 to rotate, master gear 8 and travelling gear 11 drive each equidirectional rotation of driven gear 6 that screws out mechanism, thereby drive ejector pin 52 to rotate.As shown in Figure 2, because product 100 has two convex shoulders 101, so product 100 can not limited and can rotate by moving platen 2.Meanwhile, due to the cause of spring 7, in the time that ejector pin 52 rotates, spring 7 can drive moving platen 2 constant speed and lift away from described backing plate 3.In the time that the stroke of moving platen 2 arrives the range of journey stop gear 10, described ejector pin 52 departs from completely from product 100, and the internal thread of described product 100 completes.Further, injection machine push rod 12 promotes ejector sleeve cover 51 product is released, thereby completes the injection moulding demoulding of a collection of product.
After the product after the demoulding is removed, solid plate 1 and moving platen 2 matched moulds, and Compress Spring 7 is that backing plate 3 resets, and so just reached the condition of injection moulding next time.Therefore adopt apparatus of the present invention, compared with the traditional tooth bar demoulding, the demoulding is rapid, and production efficiency is high, is especially applicable to being with female medical transfusion part product fast demoulding.
Based on embodiments of the invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
