Problems solved by technology
The traditional cylindrical exhaust plug has no positioning design, which is easy to move under external force
Moreover, the vent hole on the upper mold has no limit structure, and the installation and adjustment of the cylindrical vent plug mainly depends on knocking
When the aluminum liquid is filling the mold, due to the impact of the aluminum liquid and gas, the cylindrical exhaust plug is easy to move up, so that the air plug mark on the surface of the casting is higher than 1mm, which needs to be manually ground off, which seriously affects the appearance quality of the wheel casting, and Low production efficiency
Affected the research and development process of this type of wheel products

Embodiment Construction
[0013] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0014] As shown in the figure: the wheel mold screw plug exhaust device in the embodiment is mainly composed of an upper template 1 and an exhaust plug 2. The upper template 1 is provided with an exhaust hole 3, and the exhaust plug 2 is installed in the exhaust hole 3. The lower end of the exhaust plug 2 is provided with an exhaust column 1a, the position above the exhaust column 1a is provided with a threaded section 1b that is thicker than the exhaust column 1a, and the threaded section 1b is provided with an external thread 1d, and is processed There is a flat potential 1c; the lower section 3a of the vent hole 3 on the upper template 1 matches the size of the exhaust column 1a, the upper section 3b of the vent hole 3 is provided with an internal thread 3c, and the internal thread 3c and the exhaust plug 2 The external thread 1d on the threaded section 1b is m...

The invention relates to a wheel mold screw plug exhaust device, comprising an upper template and an exhaust plug, the upper template is provided with an exhaust hole, and the exhaust plug is installed in the exhaust hole, and the feature is that: the lower end of the exhaust plug is provided with Exhaust column, the part above the exhaust column is provided with a threaded section thicker than the exhaust column, the threaded section is provided with external threads, and is processed with a flat shape; the lower section of the exhaust hole on the upper template is connected with the exhaust The size of the air column is suitable, and the upper section of the exhaust hole is provided with an internal thread, and the internal thread is adapted to the external thread on the threaded section of the exhaust plug. The invention has simple and ingenious structure, convenient installation and adjustment, can effectively prevent the exhaust plug from moving due to the impact of aluminum liquid and gas, ensure that the height of the air plug print meets requirements, and improve the appearance quality of the wheel casting.
Description
Technical field [0001] The invention involves the exhaust device of a wheel mold when pouring. Specifically, it is a wheel mold threading exhaust device. Background technique [0002] There is a gravity -cast aluminum -aluminum wheel, which requires the quality of the gas seal between 0 ~ 1mm.Traditional cylindrical exhaust plugs have no positioning design, external forces, and easy to move.In addition, the exhaust holes on the upper mold have no limit structure. The installation adjustment of cylindrical exhaust is mainly dependent on knocking.When the aluminum is charged, due to the impact of aluminum and gas, cylindrical exhaust plugs are easy to move upwards, making the gas plugs on the surface of the casting higher than 1mm, and it needs to be manually grinded, which seriously affects the appearance quality of the wheel casting, and the appearance quality of the wheel casting, and the appearance quality of the wheel casting, and the appearance quality of the wheel casting, a...
