The solution is to adjust the injection pressure, the cooling time, or to solve the problem by an abnormal process.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a quality is lighter, the outward appearance is better, effectively solves traditional shaft cover and shrink, have bubble, the poor problem of density in surface appearance in the back product of moulding plastics, improves the lightweight shaft cover structure of shaft cover performance to overcome the weak point among the prior art.
According to a lightweight shaft lid structure of this purpose design, including apron and a plurality of leaf groove thereof, be equipped with the installation department on the apron, the apron is equipped with the annular along the peripheral extension of installation department and draws gluey groove A, and the apron corresponds to be equipped with the annular between two adjacent leaf grooves and draws gluey groove B to make installation department, leaf groove respectively the protrusion on the apron.
The annular glue drawing groove A is communicated with the annular glue drawing groove B.
The thickness of the mounting part and the thickness of the blade groove are equal.
The top surfaces of the mounting part and the leaf groove are on the same horizontal line.
The installation part is provided with a plurality of reinforcing ribs which are arranged at intervals, and the reinforcing ribs are provided with round corners connected with the installation part.
A cut-out portion for reducing mass is provided at a joint between the rounded portion and the mounting portion.
The utility model has the advantages that:
a. the cover plate is provided with an annular glue drawing groove A along the periphery of the mounting part in an extending manner, so that glue for injection molding is reduced, the cover plate is lighter in weight, the production cost is reduced, and the phenomena of shrinkage and bubbles of the cover plate after injection molding are avoided;
b. the cover plate is provided with an annular glue drawing groove B between two adjacent blade grooves correspondingly, and the blade grooves protrude on the cover plate, so that the acting capacity of the fan is facilitated;
c. the reinforcing ribs are provided with round corners connected with the mounting parts, and the right angles of the reinforcing ribs are converted into round corners, so that the performance is enhanced (the tone quality is optimized);
d. the connecting part between the round corner part and the mounting part is provided with a cutting part for reducing the mass, the glue is reduced at the connecting part between the round corner part and the mounting part, the cover plate has lighter mass, and the production cost is reduced;
in view of the above, with the above arrangement structure, such a product (shaft cap) is reduced in weight by about 8 g.
