Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds, and in particular relates to an injection molding device for a reagent disc cover. Background Art

[0002] In the experimental fields of chemistry and biology, reagent trays are important tools for experiments, and their demand continues to rise. As an important component of reagent trays, the quality and production efficiency of reagent tray covers have an important impact on the overall performance of reagent trays. Traditional reagent tray cover manufacturing methods, such as machining, casting, etc., often have problems such as low production efficiency, high manufacturing cost, and difficulty in quality assurance. With the development of injection molding technology, its high efficiency, low cost, and high quality characteristics have gradually attracted attention. Therefore, it is gradually common to manufacture reagent tray covers by injection molding. However, when the existing injection molding device manufactures the reagent tray cover, there are still some problems. The reagent tray cover produced by the existing device is relatively smooth towards one side of the reagent tray. Therefore, when there are fewer reagent tubes inside the reagent tray, due to the large gap between the reagent tubes, it is easy to produce a large amount of shaking, and it is impossible to effectively resist the reagent tubes for fixing.

[0029] Through the above technical solution, when personnel need to process the reagent disc cover, the raw material is injected into the molding cavity between the movable mold component 1 and the fixed mold component 2. After the raw material is injected, the movable mold component 1 moves relative to the fixed mold component 2 until the movable mold component 1 moves into the fixed mold component 2, so that the bottom ring 16 on the movable mold component 1 contacts the material, and the raw material in the molding cavity is waited for to be cooled and formed, thereby forming the reagent disc cover. Moreover, through the cooperation of the bottom hole 19 on the bottom ring 16, when the material forms the reagent disc cover, a convex convex point is formed on the reagent disc cover. The movable mold component 1 moves relative to the fixed mold component 2 to separate the movable mold component 1 from the fixed mold component 2, and the reagent disc cover is taken out from the molding cavity, thereby completing the processing of the reagent disc cover. When the reagent disc cover is in use, the convex points on the reagent disc cover contact the reagent tube, making the reagent tube more stable.

[0030] In addition, in the present invention, when the device processes the reagent disc cover, the shape of the side of the reagent disc cover facing the reagent disc can be adjusted, such as Figure 5-Figure 6 and Figure 8-Figure 9 As shown, a bottom plate 18 is coaxially arranged on the side of the bottom ring 16 away from the movable mold component 1, and the bottom plate 18 is equidistantly protruded outwardly in a circular array toward the side of the bottom ring 16 to form plugs 17, and the plugs 17 are detachably connected to the bottom holes 19, and a rubber ring is protruded outwardly on the peripheral surface of the plug 17.
