Description

Technical Field

[0001] The utility model relates to the relevant field of ceramic screw manufacturing, in particular to a mold for manufacturing ceramic screws. Background Art

[0002] Screws are tools that use the physical and mathematical principles of the circular rotation of the inclined surface of an object and the friction force to gradually fasten objects and parts. Screws are a general term for fasteners. With the development of material science, multifunctional screws have gradually appeared on the market, such as ceramic screws, but the processing molds for ceramic screws are relatively rare at present;

[0003] In the prior art, a utility model patent with publication number CN 212096822 U proposes a ceramic screw manufacturing mold, which is provided with a second slide groove, a second slider, a spring and a storage box, so that the workpiece falls into the storage box under the influence of gravity, and the spring contracts, thereby alleviating the impact force of the workpiece when it falls, so that the workpiece is not easily damaged due to excessive impact force of falling;

[0004] However, it does not have the demolding ability for ceramic screws. Since the formed ceramic screws are easy to stick or get stuck in the mold groove, it is necessary to manually remove the ceramic screws that have not fallen off when they fall, which is troublesome and affects the subsequent processing operations. If the screws are not found and removed in time, the secondary injection molding will fail. At the same time, it controls the mold to move and inject one by one through the conveyor belt, and the production stroke is long and the efficiency is low. Therefore, we need to upgrade and transform the existing technology to overcome its problems and shortcomings. Utility Model Content
