Description

Technical Field

[0001] The utility model relates to the technical field of injection molding of sweeping machine accessories, in particular to a peristaltic pump injection molding die for a sweeping machine. Background Art

[0002] The sweeping machine uses a peristaltic pump to deliver detergent. In fact, in the initial application, the transmission pump used for the sweeping machine was not a peristaltic pump, but a diaphragm pump. However, there are some problems when the diaphragm pump delivers detergent. First, during the transmission process of the diaphragm pump, the pump body is in direct contact with the fluid, which can easily cause corrosion of internal parts; and the sealing is weak, which can easily enter dust and damage the diaphragm pump body. Therefore, many manufacturers have abandoned diaphragm pumps and chose peristaltic pumps as the transmission power for the sweeping robot detergent. In addition, the peristaltic pump has good passability when delivering viscous liquids such as detergents. Secondly, the peristaltic pump has a metering function and can transmit liquids in a quantitative manner. When peristaltic pumps are produced, injection molds are required to perform injection molding on the pump housing.

[0003] Usually, the injection mold is slidably engaged on the mounting frame so that the mold can be easily disassembled and replaced when injecting different models. However, this makes it easy for the upper and lower injection molds to be unable to be effectively aligned, resulting in a gap between the two molds during subsequent injection molding, which can easily affect the efficiency of injection molding. Therefore, we proposed a peristaltic pump injection mold for a sweeper to solve the above problems. Utility Model Content
