Specific embodiment
The utility model is described in more detail with specific embodiment with reference to the accompanying drawing.
As shown in Figures 1 to 5, a kind of injection mold of coil component 3, injection mold includes cover half and opposite cover half can
The dynamic model of folding, cover half are distributed in above-below direction with dynamic model, and injection mold is used to be molded colloidal sol on coil rack to form line
Coil component 3, cover half include solid plate and the male die core 1 that is embedded in solid plate, and dynamic model includes moving template and is embedded in moving template
Interior mother module core 2 is formed on male die core 1 for the molding molding cavity of coil component 3, and mother module core 2 has in cover half
When pressing with dynamic model, the lid that the vent cover of multiple molding cavities is closed closes face 21；8 molding cavities are provided on male die core 1, and
8 molding cavities are located at the setting that the two sides of male die core 1 correspond；On the one side for opening up molding cavity of male die core 1
It is formed with the runner separately flowed into each molding cavity for colloidal sol, runner includes the mainstream extended along 1 length direction of male die core
Road 14, positioned at 14 both ends of sprue and the runner 15 that is arranged perpendicular to sprue 14, every one end two sides of runner 15 point
It is not provided with flow-guiding structure, runner 15 is connected to setting with molding cavity by flow-guiding structure.In addition, the bottom of each molding cavity
Face offers jogger hole, for placing mandril in order to which de- material, sprue 14 and runner 15 are also equipped with jogger hole, also uses
In placement mandril in order to de- material.Lid conjunction face 21 is the bottom plane of mother module core 2, when dynamic model is pressed together on cover half, mother module core 2
Bottom plane lid closes on molding cavity and runner.Offer the through-hole 22 through its thickness direction on mother module core 2, when injection molding,
Colloidal sol enters in runner from the through-hole 22, and then enters in each molding cavity.
In addition, the bottom plane of mother module core 2 is also formed with 8 protrusions 23 corresponding with 8 molding cavities, it is used for
Shrinkage pool is formed on coil component 3, which is used for the subsequent installation of coil component 3.
Specifically, molding cavity includes interconnected placed cavity 11 and glue injection cavities, and placed cavity 11 is for placing coil bone
Frame, glue injection cavities are used to inject colloidal sol, and, colloidal sol is attached on the coil rack being placed in placed cavity 11.Glue injection cavities are molding
Cavity in cavity in addition to placed cavity 11.In this example, placed cavity 11 is located at the bottom of molding cavity, glue injection cavities include be located at
The range of first the first chamber of chamber 12(12 at the top of cavity is greater than placed cavity 11, therefore shape between the first chamber 12 and placed cavity 11
At there is step 10) and set on molding cavity bottom and be located at placed cavity 11 side the second chamber.Second chamber includes multiple
The vertical slot 13 vertically extended, multiple vertical slots 13 are distributed in the correspondence two sides of placed cavity 11 in one-to-one corresponding states.
In this example, flow-guiding structure includes diversion trench 16, and diversion trench 16 has the flow-guiding mouth 160 being connected to molding cavity.It should
The height of flow-guiding mouth 160 in above-below direction is 0.26mm.Flow-guiding mouth 160 opens up minimum, does not cause brokenly to change to molding cavity, protects
