A kind of polymer powder slush molding test method and device

Abstract

The invention discloses a molding test device for polymer powder slush moulding. The device comprises a slush molding rack; a powder hopper mechanism; a driving mechanism used for driving the powder hopper mechanism to rotate; a sealing mechanism used for sealing the powder hopper mechanism and isolating heat; a stop mechanism used for preventing rotation of the powder hopper mechanism when the powder hopper mechanism is stalled; a rotation amount calibration mechanism used for calibrating the rotation amount of the powder hopper mechanism; a mobile guide plate used for changing the flowing direction of the slush molding powder by changing the position of the mobile guide plate in the powder hopper mechanism; and the mold used for heating the slush molding powder, wherein the powder hopper mechanism is capable of rotating around a shaft in the slush molding rack, and the powder hopper mechanism is used as a closed container for heating slush molding powder by a mold, and used for providing a visual window for a test. The device is simple and ingenious, and can be operated conveniently. The using amount of the materials used for slush molding is little. The test cycle is short and the cost is low. Test simulation of a whole slush molding process can be achieved. The device is particularly suitable for developing the slush molding powder and products thereof, and for designing slush molding process parameters, and can promote development of slush molding technology and industry.

Description

technical field [0001] The invention relates to a test method and device in the field of slush molding technology, in particular to a polymer powder slush molding test method and device suitable for the development of slush powder and its products and the design of slush process parameters. Background technique [0002] The polymer powder slush molding process is generally used to form the skin of mid-to-high-end automotive interior parts, such as the skin of armrests, headrests, door trim panels, instrument panels, and ceiling panels. The skin formed by this process has the advantages of beautiful texture, comfortable hand feeling, uniform thickness, good elasticity and mechanical strength, and can be formed into products with complex shapes. At the same time, with the development of the automobile industry, the demand for slush plastic products continues to increase. [0003] In the slush molding process, the preheating temperature and plasticizing temperature of the mold...
