Abstract
The utility model discloses a novel runner structure. The novel runner structure comprises runners, the novel runner structure is characterized in that an inner wall of a crossing position of the two runners is provided with a transition circular bead, and the runners are provided with a scorch-preventing mechanism. The novel runner structure provided by the utility model aims to overcome the disadvantages of the prior art, the structure is simple, the processing is convenient, and an injection molding scorch phenomenon is effectively prevented.
Description
Technical field
The utility model relates to a kind of novel flow channel structure.
Background technology
After existing mold runner processing, be generally left intact.Tend to like this produce runner thimble and eject difficulty, product stuffing pressure is large, and product surface does not reach the problems such as requirement.Because the wedge angle of runner and runner intersection can produce very large resistance when filling, make injection pressure loss serious; While having multi-stage path, the route of sizing material arrival product die cavity is longer, tends to produce and burns phenomenon.
So existing flow passage structure awaits further perfect.
Utility model content
The purpose of this utility model is in order to overcome weak point of the prior art, provides a kind of simple in structure, easy to process, can effectively prevent that injection moulding from burning the novel flow channel structure of phenomenon.
In order to achieve the above object, the utility model adopts following scheme:
A novel flow channel structure, includes runner, it is characterized in that: on two runner intersection inwalls, be provided with knuckle, be provided with the anti-mechanism of burning on described runner.
A kind of novel flow channel structure as above, is characterized in that describedly anti-burn mechanism and comprising the air discharge duct that is located at flow field end.
A kind of novel flow channel structure as above, is characterized in that being provided with closeouts in described air discharge duct.
A kind of novel flow channel structure as above, is characterized in that the angle at described knuckle is 30-60 °.
In sum, the utility model with respect to its beneficial effect of prior art is:
The utility model is simple in structure, on runner intersection inwall, is provided with knuckle, and effect guarantees sizing material smooth flow when filling, and injection pressure loss is dropped to minimum; End at every runner is offered air discharge duct, can allow the air in runner while filling discharge smoothly, thereby can not produce and burn phenomenon, and the surface quality of product also significantly improves.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing explanation and the specific embodiment, the utility model is further described:
A kind of novel flow channel structure as shown in Figure 1, includes runner 1, on two runners, 1 intersection inwall, is provided with knuckle 2, is provided with the anti-mechanism 3 of burning on described runner 1.
Described in the utility model, prevent that burning mechanism 3 comprises the air discharge duct 4 that is located at runner 1 end.
In the utility model, in described air discharge duct 4, be provided with closeouts.
Angle at described knuckle 2 in the utility model is 30-60 °.
The utility model is simple in structure, on runner intersection inwall, is provided with knuckle, and effect guarantees sizing material smooth flow when filling, and injection pressure loss is dropped to minimum; End at every runner is offered air discharge duct, can allow the air in runner while filling discharge smoothly, thereby can not produce and burn phenomenon, and the surface quality of product also significantly improves.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
