Abstract: An automatic mold cleaning device includes an automatic cleaning system, a mold clamping system and a waste recovery system.

Abstract: The present disclosure belongs to the technical field of automobile chassis suspension system tests, and provides a wheel acceleration torque system and test equipment for an automobile chassis simulation road test. The automatic connection and separation mechanism is connected with a transmission shaft of a wheel; the automatic connection and separation mechanism can apply acceleration torque of the torque shaft to the transmission shaft, and can separate the acceleration torque applied to the transmission shaft; and the wheel acceleration torque system and the test equipment can adapt to the requirement for applying the acceleration torque in a test of a test bench, simulate to apply the acceleration torque which the wheel bears in the actual road running process, ensure that a test state of a tested wheel and suspension system is close to a test state of a real automobile test field.

Abstract: The present disclosure belongs to the technical field of automobile chassis suspension system tests, and provides a loading system and test equipment for an automobile chassis simulation road test.

Abstract: The application provides a cooling water channel for a casting mold. The cooling water channel adopts a sealing structure in which a water channel insert, a sealing cover plate and a metal corrugated sealing ring are matched with each other, wherein a bottom surface of the metal corrugated sealing ring is corrugated or two side walls of the metal corrugated sealing ring are corrugated, and the sealing cover plate is pressed to enable the metal corrugated sealing ring to generate elastic deformation, so that corrugations on the two side walls of the metal corrugated sealing ring and a side wall of the water channel form multi-point contact or the bottom surface of the metal corrugated sealing ring expands to make the side walls of the metal corrugated sealing ring in tight contact with the water channel to achieve a water channel sealing effect.

Abstract: A wheel weight-reducing pit cleaning device is provided. The wheel weight-reducing pit cleaning device comprises a lower lifting driving system, a side brush system, a ring brush unit, a ring brush system, a clamping driving system, a pressing system. The weight-reducing pit cleaning device is used for cleaning and removing the edge burrs of the drainage groove and the weight reduction groove at the wheel weight reduction pit.

Abstract: A device for removing wheel burrs with first brushes and second brushes includes a wheel positioning and pressing system configured to position and press of the wheel, a center cap mouth burr removing system configured to remove burrs of the wheel cap mouth with the second brushes, and a wheel spoke back cavity burr removing system configured to remove burrs of the wheel spoke back cavity with the first brushes. The first brushes are mounted on an expandable first capsule and the second brushes are mounted on an expandable second conical capsule, and filling the expandable first capsule and the expandable second conical capsule with air and removing air from the expandable first capsule and the expandable second conical capsule change the shapes of the first brushes and the second brushes to accommodate wheels with different shape and size for deburring.

Abstract: The present application relates to an adjustable wheel deburring device, comprising a lower lifting-translating-overturning system, a clamping driving system, a upper lifting-moving system, a adjusting system, a brush unit and a upper deburring system, among others. The device according to the present invention in use is able to not only remove burrs at the back cavity and front of the wheel, but also automatically adjust the shape of the brush belt according to the shape of the wheel back cavity.

Abstract: The present application relates to a wheel with a sound absorber, the sound absorber being mounted in a wheel air chamber to reduce acoustic resonance, wherein the sound absorber is configured as a flat hexahedral box resonator and fastened to a wheel hub through a band, a first positioning mechanism is provided between the hub and the box resonator to fix the relative positions of the hub and the box resonator, and a second positioning mechanism is provided between the box resonator and the band to fix the relative positions of the box resonator and the band. According to the technical solution of the present disclosure, the resonator is positioned and fixed more reliably on the wheel, and the wheel is simple and economical in manufacturing, and convenient and controllable in installation and operation.
