Description

Technical Field

[0001] The utility model relates to the technical field related to injection molding processing molds, in particular to a common processing mold for centrifuge tube covers with multiple specifications. Background Art

[0002] A mold refers to a mold or tool that uses external force to form a blank into a specific shape and size through methods such as injection molding, extrusion, and die-casting. Molds are classified into hardware molds, plastic molds, and special molds according to their materials. Driven by high technology and the application needs of pillar industries, plastic molds have formed a huge industrial chain from the raw and auxiliary materials industry and processing and testing equipment to industries such as machinery, automobiles, home appliances, and building materials. Plastic molds are made by injecting molten plastic into the molding cavity. After cooling and shaping, an ejection system is used to eject the product out of the mold cavity.

[0003] After massive searches, it was found that the Chinese patent announcement number is CN221392046U, which discloses a pipette tip processing mold, which includes, from top to bottom, a heat insulation plate, an upper fixed seat, a hot runner plate, a fixed mold pad, a mother mold plate, a movable mold push plate, a movable mold support plate and a lower fixed seat. A hot filling nozzle is installed in the middle position of the heat insulation plate, and several fixed mold assemblies are installed between the fixed mold pad and the movable mold support plate; a hot filling accommodating cavity is provided on the upper fixed seat directly below the hot filling nozzle, and a discharge pipe is installed on the part of the hot filling nozzle located in the hot filling accommodating cavity, and hot filling guide pipes are provided on both sides of the hot filling nozzle along the X-axis direction.
