Technical Field
The utility model relates to a limit for height frock, in particular to empty PU filter core end cover injecting glue shaping plastics mould limit for height frock of straining.
Background
Because the filter element end cover of the air filter PU structure is formed by freely foaming after mixing two-component PU sizing material, a common mould for PU end cover glue injection forming comprises a plastic mould and a steel mould, and the height limit tools used by the two moulds are different. Described herein is the use of a plastic mold height limiting fixture. The PU end cover of the same product has uniform size requirement, the height is consistent, the upper end surface and the lower end surface are required to be smooth, the upper end surface is ensured to be smooth through a plastic die, and the lower end surface and the height are required to be provided with a height limiting tool to be combined with the plastic die to ensure the height and the end surface of the PU end cover to be smooth. The existing height limiting tool is composed of a bottom plate, a positioning pin, a rear limiting plate, a quick clamping assembly, a circular pressing plate and the like, is complex in structure, large and heavy in size, multiple in operation steps, high in manufacturing cost, large in occupied area, large in production, use, replacement or carrying labor intensity, time-consuming, inconvenient to operate and low in working efficiency.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: the utility model provides an empty PU filter core end cover injecting glue shaping plastic mold limit for height frock of straining, this frock low in manufacturing cost, take up an area of for a short time, production convenient to use is swift, has improved work efficiency, has solved the problem that above-mentioned prior art exists.
The technical scheme for solving the technical problems is as follows: the utility model provides an empty PU filter core end cover injecting glue shaping plastic mold limit for height frock of straining, this frock is the ring structure of constituteing by two semi-circular ring shape draw-in groove formula flat plate frock, semi-circular ring shape draw-in groove formula flat plate frock includes cardboard and lower cardboard, it is the semicircle crown plate to go up the cardboard, the cardboard is the semicircle crown plate that its edge has the boss down, goes up cardboard bottom surface edge and the boss fixed connection of cardboard down, goes up the cardboard and forms the draw-in groove that is used for chucking plastic mold border with lower cardboard, and the height ratio at this draw-in groove is 0.1 ~ 0.25mm great than the thickness at plastic mold border.
The inner edge of the semicircular ring plate of the lower clamping plate is provided with a chamfer which is convenient to buckle into the edge of the plastic mould.
The diameter of the inner circle of the circular ring structure formed by the two upper clamping plates is 1-2 mm larger than that of the filter material component of the air filter PU filter element.
Adopt the utility model discloses it is tight along the plastic mold border clamp to fix a position with plastic mold maximum outer diameter, mould border thickness and mould top surface, in filter core PU end cover injecting glue foaming forming process, location benchmark, limit for height homoenergetic at every turn are the same, have restricted the PU end cover superelevation or have appeared terminal surface unevenness phenomenon, have guaranteed PU end cover height dimension unanimity, not superelevation, terminal surface level and smooth requirement.
The utility model discloses frock practicality, commonality are strong. The tool has the advantages of simple structure, easy processing, light weight, wear resistance and long service life. The manufacturing cost is reduced, and the floor area for production or storage is reduced. In the production and use process, the operation is simple and easy, the use is convenient and fast, the working procedures are reduced, the production cost is reduced, and the production efficiency is greatly improved.
The technical features of the height limiting tool for the air filter PU filter core end cover glue injection molding plastic mold of the present invention will be further described with reference to the accompanying drawings and embodiments.
