Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, and in particular relates to a horn gate mold structure for use with LCP material. Background Technology

[0002] LCP material has the characteristics of high strength and fast crystallization. The commonly used injection methods are submarine gate, spot gate and side gate. If it is to produce thin-walled workpieces, the appearance of the workpiece must not be abnormal. In this case, submarine gate and side gate are not suitable, while spot gate will increase the mold cost.

[0003] For products with high appearance requirements and limited injection points, horn gates are the best choice. However, horn gates are usually used for materials that are not easily broken, such as LCP. Because LCP is easy to break, horn gates are less effective.

[0004] Therefore, it is necessary to improve the structure of the horn gate mold to design a horn gate mold structure that can be used for LCP materials, so as to achieve mass production, solve product appearance defects and save manufacturing costs. Utility Model Content

[0005] This invention provides a horn-shaped gate mold structure for use with LCP materials to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A horn-shaped gate mold structure for use with LCP materials includes a horn-shaped gate mold, characterized in that the horn-shaped gate mold is designed and formed with a front gate and a horn-shaped runner; the horn-shaped runner is a curved cone with a gradually decreasing cross-sectional size; the front gate is located at the connection between the horn-shaped runner and the product; the outlet of the front gate is a circular outlet design, and the outlet is a boss structure on the horn-shaped gate mold; based on the same plane, the angle between the tangent of the central axis of the front gate and the central axis of the runner is between 15° and 30°.

[0007] Compared with existing technologies, the advantages of this utility model are: This invention improves the curvature of the rear half of the horn-shaped runner. Compared to the circular curvature, the angle between the tangent of the runner's central axis and the central axis of the gate is too small, resulting in an excessive instantaneous rise in curvature of the material before it exits from the front gate. This invention reduces the curvature of the front gate by increasing the angle, thus reserving more deformation space. This detailed design ensures that even when using LCP material for injection molding, breakage at the front gate will not occur. Attached Figure Description

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] like Figure 1 and Figure 2 As shown, this utility model is a horn-shaped gate mold structure for use with LCP materials, including a horn-shaped gate mold 1. The horn-shaped gate mold 1 is designed and formed with a front gate 2 and a horn-shaped runner 3; the horn-shaped runner 3 is a curved cone with a gradually decreasing cross-sectional size; the front gate 2 is located at the connection between the horn-shaped runner 3 and the product; the outlet 20 of the front gate 2 is a circular outlet design, and the outlet 20 is a boss structure design on the horn-shaped gate mold 1.

[0012] The main technical point of this structure is that, based on the same plane, the angle between the central axis 21 of the front gate 2 and the tangent 31 of the central axis 30 of the runner 3 is controlled within the range of 15° to 30°. This structural design can improve the problem of excessive instantaneous curvature rise of the material before discharge from the front gate 2. Compared with the small angle between the tangent 31 of the runner central axis 30 and the central axis 21 of the gate under a perfect circular curvature, this utility model achieves a slower curvature of the front gate 2 by increasing the angle, so as to reserve more deformation space. This detailed design can ensure that even when using LCP material for injection molding, there will be no breakage at the front gate 2.
