Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", and the like, indicate the orientation or positional relationship indicated based on the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The deep cavity venting system as shown in fig. 1 to 9 comprises a deep cavity 1 and a venting insert 2, wherein the venting insert 2 is installed at a position of a boss 3 in the deep cavity 1, the venting insert 2 comprises a venting insert 21 and a support rod 22, the venting insert 21 and the support rod 22 are assembled to form an integrated structure and installed at the position of the boss 3 on the deep cavity 1, and gas in the deep cavity 1 is vented through the venting insert 21.

In this embodiment, one end of the exhaust insert 21 is provided with a clamping groove 211, one end of the support rod 22 is provided with a protrusion 221 adapted to the clamping groove 211, the clamping groove 211 and the protrusion 221 are in an Ω -shaped structure, on one hand, the installation or the disassembly of the exhaust insert 21 and the support rod 22 only needs to clamp or separate the protrusion 221 of the support rod 22 from the clamping groove 211 of the exhaust insert 21, which is convenient and quick, on the other hand, the support function of the exhaust insert 21 with different sectional areas can be realized only by ensuring that the clamping groove 211 of the exhaust insert 21 is adapted to the protrusion 221 of the support rod 22, the exhaust insert 21 with different sectional areas can be selected according to the actual exhaust volume, the exhaust efficiency is improved by adjusting the contact area between the exhaust insert 21 and the deep cavity 1 of the mold, and the problem.

In this embodiment, all the surfaces of the exhaust insert 21 are provided with the exhaust micropores 212, so that the whole exhaust insert 21 can exhaust, the exhaust amount is greatly increased, and the exhaust requirement of the deep cavity 1 of the mold is met.
