The invention provides test equipment for an automotive plastic oil sump and belongs to the technical field of detecting techniques. The test equipment solves the problem in the prior art that oil sumps are troublesome in detection. The test equipment for the automotive plastic oil sump comprises a base, a frame and a controller. The test equipment is characterized in that a support rod is fixedly arranged on the base. The top end of the support rod is fixedly provided with a screw-down cylinder. The piston of the screw-down cylinder is connected with a sliding plate. The sliding plate is slidably sleeved onto the support rod. The bottom of the sliding plate is fixedly provided with a cylinder. The piston of the cylinder is fixedly provided with a choke plug. The bottom of the sliding plate is also provided with a pressure rod. A test bench is arranged on the base. The edge of the test bench is connected with hinges at the middle parts of a plurality of clamping rods. One ends of the clamping rods are in hinge connection with the piston of a clamping cylinder. The test bench is provided with a charging port and an air pressure detector. The charging port is connected with an air charging apparatus. According to the technical scheme of the invention, the detection efficiency for detecting the air tightness of an oil sump is greatly improved.
