This utility model relates to motorcycle or two wheeler parts manufacturing technology field, uses curved shunting particularly to one Road front panel core device.

Background technology

Motorcycle or two wheeler front panel are as the profile plastic critical piece of vehicle, the tidiness of its outward appearance and integrity degree Have impact on the aesthetic appearance of entirety, but exploitation designs some novel vehicles when, in order to pursue more novel moulding, Generally its structure can be complex.In injection moulding process, would generally set between sprue end and cast gate in die cavity or core In score runner, particularly multiple-cavity mold, the design of sub-runner is requisite, but at existing motorcycle or two-wheeled In the front panel injection forming mold of car, it is cold compared with big, drain inconvenience and melt that the design of its sub-runner is usually present intrinsic pressure loss Speed defect faster.

Utility model content

The purpose of this utility model is to solve above-mentioned deficiency, it is provided that a kind of employing curved sub-runner front panel core dress Put, there is simple in construction, reasonable in design, drainage effect is good in injection, the inefficient feature of cold burden.

This utility model is solved the technical problem that to realize by the following technical solutions:

The curved sub-runner front panel core device of a kind of employing, including a pedestal, described pedestal is rectangular structure, described Being respectively equipped with a guide pillar hole at pedestal corner, side, described guide pillar hole is provided with a release link, is provided with one at described pedestal long side Datum hole, is core plan in the middle part of described pedestal, is provided with a sub-runner in the middle part of described core plan, described sub-runner by bifurcated runner and Curved runner integrally connects and composes, and described bifurcated runner is made up of arced flow path and the straight channel of front end, described straight channel one end with Communicating in the middle part of described arced flow path, the described straight channel other end communicates with described curved runner, and described curved runner is semicircle hook knot Structure, is provided with a cavity forming wall in triangular shape outside described sub-runner, described core plan side is provided with some slanted kicking blocks, described Two dome pins it are provided with at core plan small end.

Described curved flow channel cross-section is semi arch structure.

Described straight channel cross section is inverted trapezoidal structure.

Described arced flow path cross section is semi arch structure.

Described curved flow channel cross-section radius size is more than described arced flow path cross sectional radius size.

Described curved flow channel cross-section radius size is 1.3 ~ 1.5 times of described arced flow path cross sectional radius size.

This utility model compared with prior art has following outstanding advantages and effect: this utility model uses bifurcated runner With curved runner combinative structure, optimizing sub-runner structure, convenient guiding plastic cement enters die cavity, has the effect reducing cold burden, with Shi Caiyong slanted kicking block and dome pin combinative structure, improve the demoulding efficiency of product, has simple in construction, reasonable in design, injection Effective feature.

Feature of the present utility model see graphic and the most preferably embodiment the detailed description of this case and obtains clear Ground is understood.
