Description

Technical Field

[0001] This utility model relates to industrial testing equipment, and more specifically to a tire mold air hole sleeve air flow detection device. Background Technology

[0002] Vent sleeves are widely used in tire molds, industrial machinery, and other fields, playing a vital role in ventilation and exhaust. In existing technologies, the airflow performance testing of vent sleeves typically relies on manual testing or simple equipment, which is insufficient to meet the demands for efficient and accurate testing. Therefore, developing an efficient and accurate vent sleeve airflow testing device is of great significance. For example, patent CN115200662A discloses an auxiliary device for detecting airflow through a small orifice of an aerosol actuator. This device introduces detection gas into one end of the vent on its chassis. After pressing the inner rod, the nozzle at the top of the inner rod ejects the detection airflow. The detection data for the relevant orifice is determined based on the magnitude of the airflow passing through the small orifice of the actuator, i.e., the reading of the pneumatic gauge. However, a drawback of this patent is that it cannot adapt to vent sleeves of different sizes and specifications. Utility Model Content
