[0031] like Figure 1-2 As shown, an embodiment of the present application provides an electrode body for adjusting a mold cavity, including an electrode body 1, a first vertical surface 111 and a first inclined surface 112 are provided on the outer side surface 11 of the electrode body 1, the lower end of the first inclined surface 112 is connected to the upper end of the first vertical surface 111, and the upper end of the first inclined surface 112 is inclined toward the outer side of the electrode body 1, and the first vertical surface 111 and the first inclined surface 112 form an angle.

[0032] In this embodiment, when the mold cavity needs to be adjusted and formed, the shape of the mold cavity can be adjusted and formed by simply inserting the electrode body 1 into the corresponding mold cavity so that the shape of the mold cavity is consistent with the shape of the electrode body 1. In addition, the first vertical surface 111 and the first inclined surface 112 of the electrode body 1 can be adjusted according to the size of the product.

[0033] By setting a first vertical surface 111 and a first inclined surface 112 on the outer wall of the electrode body 1, the electrode body 1 is inserted into the mold cavity to adjust the shape of the cavity and form it, so that the side walls in the mold cavity corresponding to the first vertical surface 111 and the first inclined surface 112 of the electrode body 1 form the same shape and inclination angle, thereby adjusting the demolding angle of the product. When the processing is completed, it can effectively avoid the mold from dragging the product when the product is demolded.

[0034] In one embodiment, the angle between the first vertical surface 111 and the first inclined surface 112 is configured as a rounded chamfer or an oblique chamfer.

[0035] In this embodiment, the angle where the first vertical surface 111 and the first inclined surface 112 are connected is set as a round chamfer or an oblique chamfer, the purpose of which is to make a smooth transition treatment at the angle where the first vertical surface 111 and the first inclined surface 112 are connected. By setting it in this way and adjusting the mold cavity to form it, it is also possible to further avoid the mold from dragging the product when demolding.

[0036] like Figure 3-8 As shown, an embodiment of the present application provides a mold, including a mold core 2, on which an annular groove 21 is formed;

[0037] The jig 3 is arranged on the mold core 2, and the inner side wall of the jig 3 is connected to the outer side wall of the annular groove 21 and forms an injection groove 4 with the annular groove 21. The outer side wall of the injection groove 4 includes a second vertical surface 41 and a second inclined surface 42. The lower end of the second inclined surface 42 is connected to the upper end of the second vertical surface 41, and the upper end of the second inclined surface 42 is inclined toward the outer side wall of the jig 3;

[0038] The shape of the injection molding groove 4 matches the electrode body, the second vertical surface 41 is aligned with the first vertical surface 111 , and the second inclined surface 42 is aligned with the first inclined surface 112 .

[0039] In this embodiment, a parting surface 22 is provided at the top of the mold core 2, and a second vertical surface 41 is perpendicular to the parting surface 22. The shape of the injection groove 4 is adjusted and formed by the electrode body 1. The second vertical surface 41 and the second inclined surface 42 are formed by inserting the electrode body 1 into the injection groove 4 and adjusting and forming the electrode body 1. In this way, a trumpet-shaped opening is formed at the opening of the injection groove 4, which can increase the angle of the product when it is ejected from the mold, prevent the injection groove 4 from dragging the product when it is ejected from the mold, and eliminate the process of avoiding the inner wall of the electrode body, thereby ensuring that no step difference is formed when the product is injected.

[0040] In one embodiment, the mold core 2 and the fixture 3 are detachably connected.

[0041] In this embodiment, the mold core 2 and the jig 3 are provided with a detachable connection, so as to facilitate maintenance and adjustment of the mold core 2 and the jig 3 .

[0042] In one embodiment, a parting surface 22 is provided at the top of the mold core 2, and at least two connecting grooves 23 are provided at the edge of the parting surface 22. The bottom surface of the jig 3 is provided with protrusions 31 that are consistent in number, position, and shape with the connecting grooves 23. When the mold core 2 is connected to the jig 3, the protrusions 31 are inserted into the connecting part.

[0043] In this embodiment, during assembly, the protrusion 31 of the jig 3 is aligned with the connecting groove 23 so that the protrusion 31 is inserted into the connecting groove 23, thereby completing the assembly of the jig 3 and the mold core 2. The connecting groove 23 also has a positioning function, allowing the jig 3 to be accurately installed in the corresponding position.

[0044] Optionally, the two connecting grooves 23 are symmetrically arranged;

[0045] Optionally, the number of the connecting grooves 23 is four, and they are symmetrically arranged in pairs on the edge of the parting surface 22 of the mold core 2 .

[0046] like Figure 9As shown, in one embodiment, a height H from the lower end of the second vertical surface 41 to the parting surface 22 is less than or equal to 3.5 mm.

[0047] A height h from the lower end of the second inclined surface 42 to the parting surface 22 is less than or equal to 1.75 mm.

[0048] In this embodiment, the height H from the lower end of the second vertical surface 41 to the parting surface 22 needs to be less than or equal to 3.5 mm. The purpose is to make the electrode body module designed in this way more suitable for products with a H less than or equal to 3.5 mm. If the H is greater than 3.5 mm, this method will have little effect on improving drag damage.

[0049] Optionally, when the height H from the lower end of the second vertical surface 41 to the parting surface 22 is less than or equal to 1.5 mm, the height h from the lower end of the second inclined surface 42 to the parting surface 22 is equal to 1 / 2H.

[0050] Optionally, when the height H from the lower end of the second vertical surface 41 to the parting surface 22 is greater than 1.5 mm, the height h from the lower end of the second inclined surface 42 to the parting surface 22 is less than or equal to 0.75 mm.

[0051] It should be noted that the draft angle adjustment amount should be as large as possible within the tolerance range. At the same time, the maximum electrode interference d caused by fine-tuning the draft angle needs to be adjusted within the product size tolerance range. At the same time, the electrode body 1 can be directly adjusted to achieve the purpose of adjusting the above parameters.

[0052] Through the above settings, the transition from manual labor to CNC processing is achieved during mold-saving operations, so that there are standards for reference and measurement, the processing data is uniform and stable, and it is not easy to form step differences at the product parting point.

[0053] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
