Description
Technical field
The utility model is related to a kind of mold ejection mechanism, especially a kind of tunnel gate postpones runner ejecting mechanism.
Background technology
When the injection molding for being carried out product using injection mold is operated, the material of melting is flowed into cavity by cast gate
In, in cavity after cooling after solidification forming, recycle ejecting mechanism that will be ejected in its mold cavity from die opening state.If
When to enter glue runner be sub-marine gate, due to being a certain included angle between its cast gate and die joint, the mistake in this way in product ejection
Cheng Zhong, it is possible that the case where scratching product when cast gate is detached with molded part；Or when product is smaller, molding machine ejection
Because of stress relation when product, product calving phenomenon is easy tod produce, can equally product be caused to scratch；The above problem can all cause to make
The decline of product quality.Therefore need one kind being capable of solution to the problems described above or device now.
Invention content
The utility model is to propose that one kind is simple in structure, design is skilful to solve the above-mentioned deficiency present in the prior art
It is wonderful, it is rationally distributed, it can prevent from causing the tunnel gate scratched to postpone product at tunnel gate during ejecting product
Runner ejecting mechanism.
The technical solution of the utility model is：It is pressed from both sides under a kind of tunnel gate delay runner ejecting mechanism, including mould bases
Plate 1, it is characterised in that：The mould bases lower clamp plate 1 has been sequentially arranged above lower ejector retainner plate 2 and upper ejector retainner plate 3, in upper ejector retainner plate 3
Top be then provided with drawer at movable side mould bases backing plate 4, and the top of drawer at movable side mould bases backing plate 4 is then provided with drawer at movable side mould bases plate 5,
It is provided with the ejection column 6 that lower ejector retainner plate 2 can be driven to move in lower clamp plate 1, counterbore 7, counterbore 7 are offered in lower ejector retainner plate 2
Inside it is connected with T-type pin 8, the top of T-type pin 8 is connected with runner ejector pin 9, in the core 10 in the drawer at movable side mould bases plate 5
Runner 11 and cavity 12 are offered, top and the runner 11 of the runner ejector pin 9 match, and product is provided in upper ejector retainner plate 3
Thimble 13, top and the cavity 12 of the product thimble 13 match.
The utility model compared with the existing technology, has the following advantages that：
The tunnel gate of this kind of structure type postpones runner ejecting mechanism, simple in sturcture, ingenious in design, rationally distributed,
It for traditional mold with tunnel gate in the injection molding of progress product, often because at tunnel gate and die joint
Between there are problems that scratching product caused by angle, design a kind of special ejecting mechanism, it utilizes mating counterbore
With T-type pin, to realize the sequentially-operating of runner ejector pin and product thimble（Asynchronous action）, and then ensure that product is located surely completely
Afterwards, the waste material in runner could eject, and can effectively prevent in this way at tunnel gate for the issuable scuffing problem of product.
And its manufacture craft is simple, and manufacturing cost is cheap, it can be said that it has a variety of advantages, particularly suitable in ability
It is promoted and applied in domain, market prospects are very wide.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific implementation mode
Below in conjunction with description of the drawings specific embodiment of the present utility model.As shown in Figure 1：A kind of tunnel gate delay
Runner ejecting mechanism, including mould bases lower clamp plate 1, ejector retainner plate 2 and upper ejector retainner plate under being sequentially arranged above of mould bases lower clamp plate 1
3, then it is provided with drawer at movable side mould bases backing plate 4 in the top of upper ejector retainner plate 3, and be then provided with can for the top of drawer at movable side mould bases backing plate 4
Dynamic side form frame plate 5, the ejection column 6 that ejector retainner plate 2 moves under capable of driving is provided in lower clamp plate 1, is opened up in lower ejector retainner plate 2
There is counterbore 7, T-type pin 8 is connected in counterbore 7, the top of T-type pin 8 is connected with runner ejector pin 9, the drawer at movable side mould bases plate 5
In core 10 in offer runner 11 and cavity 12, top and the runner 11 of the runner ejector pin 9 match, in upper ejector retainner plate 3
It is inside provided with product thimble 13, top and the cavity 12 of the product thimble 13 match.
The course of work of the tunnel gate delay runner ejecting mechanism of the utility model embodiment is as follows：After product molding,
Mold molds, and ejection column 6 drives lower ejector retainner plate 2, upper ejector retainner plate 3 to move upwards simultaneously, due to upper ejector retainner plate 3 directly with product top
The bottom end of needle 13 is connected, therefore upper ejector retainner plate 3 directly can drive product thimble 13 to move upwards, and product is ejected from cavity；
And during lower ejector retainner plate 2 moves, due between the counterbore 7 in lower ejector retainner plate 2 and the top of T-type pin 8 there are gap, because
This lower ejector retainner plate 2 can't drive T-type pin 8 to move at once when moving, and 7 bottom of counterbore in ejector retainner plate 2 moves to and T-type instantly
When the bottom end contact condition of 8 Top projections of pin, lower ejector retainner plate 2 can just drive T-type pin 8 and runner ejector pin 9 thereon upward
Movement；
By the structure of the counterbore 7 and T-type pin 8 of this matching, control product thimble 13 ejection, runner ejector pin 9 first are slightly
After eject, such product and the waste material that is formed at tunnel gate one will first eject after one, to prevent at tunnel gate
Waste material the problem of scratching product.
