Abstract
The utility model relates to an improved latent type runner plate structure which comprises a cavity, a cavity fixing plate and a runner plate, wherein the runner plate is arranged below the cavity fixing plate. The improved latent type runner plate structure is characterized in that the upper surface of the runner plate is provided with an arc-shaped lug boss on a position close to the cavity; the arc-shaped lug boss is particularly arranged near a feed port; and an included angle of 5-30 degrees is formed between the arc line of the arc-shaped lug boss and a plane. After the technical scheme is adopted, the shape of a flow channel is partially changed, and the arc-shaped lug boss is milled on the flow channel near the feed port; and the improved latent type runner plate structure disclosed by the utility model has the advantages of cost saving and easiness for ejection by slightly changing the flow channel and realizes high benefit through slight change.
Description
Technical field
The utility model belongs to mould structure, is specifically related to a kind of structure of improving the submarine runner plate.
Background technology
Mould of the prior art, all comprise die cavity 1, impression bolster 2 and runner plate 3 referring to Fig. 1, at work, for the impact of the various factors such as design and product appearance, mould adopts the submarine feeding manner, if the glue angle of diving is between 30 to 45 degree, and is working properly, if but due to some specific (special) requirements and odjective cause, make the glue angle of diving surpass the words of 50 degree, fracture in the time of will having caused the runner waste material to eject, some is stayed in the material mouth, expects unsuccessfully thereby cause taking off.
Summary of the invention
The utility model provides a kind of structure of improving the submarine runner plate in order to solve the technical problem of mentioning in background technology.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of structure of improving the submarine runner plate, the runner plate that comprises die cavity, impression bolster and be arranged on impression bolster below is characterized in that: the upper surface of described runner plate is being provided with an arc bump near the die cavity place.
Described arc bump specifically is arranged near the material mouth.
The camber line of described arc bump and plane included angle are 5 to 30 degree.
After adopting above technical scheme: the local shape that changes runner, near distance material mouth, runner is milled out arc bump, advantage is that runner is changed a little, saves cost, easily ejects, and has realized little change, large income.
Description of drawings
Fig. 1 is the partial structurtes cutaway view of die cavity and runner plate in prior art;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
Referring to Fig. 2, a kind of structure of improving the submarine runner plate, comprise die cavity 1, impression bolster 2 and the runner plate 3 that is arranged on impression bolster 2 belows, the upper surface of runner plate 3 is being provided with an arc bump 4 near die cavity 1 place, arc bump 4 specifically is arranged near material mouth 5, arc bump 4 adopts the mode of milling to arrange, calculate according to the latent glue angle of reality, the camber line of arc bump and plane included angle are that 5 to 30 degree are best arc, and namely 4 needs of arc bump are slightly high gets final product with runner plate 3 top surface plane.
The improvements of the corresponding prior art of the utility model: the local shape that changes runner, near distance material mouth 5, runner is milled out arc bump 4, advantage is that runner is changed a little, saves cost, easily ejects, and has realized little change, large income.
Claims (3)
1. structure of improving the submarine runner plate, the runner plate (3) that comprises die cavity (1), impression bolster (2) and be arranged on impression bolster (2) below is characterized in that: the upper surface of described runner plate (3) is locating to be provided with an arc bump (4) near die cavity (1).
2. a kind of structure of improving the submarine runner plate according to claim 1 is characterized in that: described arc bump (4) specifically is arranged near material mouthful (5).
3. a kind of structure of improving the submarine runner plate according to claim 1 and 2 is characterized in that: the camber line of described arc bump (4) and plane included angle are 5 to 30 degree.
