Abstract
The utility model relates to a mold for making a plastic axial flow blade. The mold for making the plastic axial flow blade comprises a mold body and a shaft sleeve mold, wherein a circular hub groove, a blade groove and a reinforcing rib groove are formed on the mold body; a circular injection molding opening allowing a shaft sleeve to be accommodated is formed at the circle center of the circular hub groove on the mold body; the circular injection molding opening is communicated with the circular hub groove and the reinforcing rib groove; a shaft sleeve molding cavity is formed in the shaft sleeve mold; and the shape of the shaft sleeve molding cavity corresponds to the circular injection molding opening in a matched way. By using the mold for making the plastic axial flow blade, provided by the utility model, the problem that the shaft sleeve is easy to shrink and deform when the traditional single mold is molded by injection at one time is solved; and the mold for making the plastic axial flow blade, provided by the utility model, has the advantages of novel structure, good performance of the made plastic axial flow blade, high strength of the shaft sleeve and high accuracy of the shaft sleeve.
Description
Technical field
The utility model relates to a kind of mould of making axial-flow leaf.
Background technology
The plastics axial-flow leaf is a ventilation equipment field product commonly used; Its structure comprises circular hub, axle sleeve, reinforcement and the blade that plastics are processed; Axle sleeve is in the center of circular hub, and blade is connected on the lateral wall of circular hub, and reinforcement is between circular hub and the axle sleeve.When axle sleeve is the running of whole plastics axial-flow leaf with extraneous unique contact portion, the centrifugal force when bearing plastics axial-flow leaf gravity with running, so very high to the requirement of axle sleeve intensity, the wall thickness of axle sleeve is thicker than circular hub, reinforcement and blade.All parts of existing plastics axial-flow leaf all are that an injection moulding fuses, and the mould of therefore making the plastics axial-flow leaf is an one, and circular hub groove, axle sleeve groove, reinforcement groove and blade groove are set on it; When injection mo(u)lding, the axle sleeve that wall thickness is thicker is easy to generate contraction distortion, and this distortion has not only reduced axle sleeve intensity; Also reduced the dimensional accuracy of axis hole; Assemble with it in hole too snapshot of oneself sound motor, the vibration when Kong Taida then causes the fan blade running, the abnormal sound when having strengthened running.In sum, the mould structure of existing making plastics axial-flow leaf is single, and the intensity and the precision of the plastics axial flow blade shaft cover of making are low, and serviceability is poor.
Summary of the invention
The purpose of the utility model is the deficiency that exists for the mould that solves existing making plastics axial-flow leaf, and a kind of mould of making plastics axial-flow leaf of novel structure is provided, and the plastics axial-flow leaf serviceability of making is good, and the intensity of axle sleeve and precision are high.
In order to realize above-mentioned purpose, the technical scheme below the utility model has adopted:
A kind of mould of making the plastics axial-flow leaf; Constitute by die body and axle sleeve mould; Die body is provided with circular hub groove, blade groove and reinforcement groove, and the circle centre position of circular hub groove is provided with the circular injection molding mouth of placing axle sleeve on the die body, and the circular injection molding mouth is connected with circular hub groove and reinforcement groove; Be provided with the axle sleeve forming cavity in the axle sleeve mould, the shape of axle sleeve forming cavity is corresponding with circular injection molding mouth coupling.
As preferably, said blade groove is 3.
Adopted a kind of mould of making the plastics axial-flow leaf of technique scheme; Constitute by die body and axle sleeve mould; During injection moulding, pass through the interior axle sleeve forming cavity of axle sleeve mould earlier, then the axle sleeve of moulding is put into the circular injection molding mouth on the die body as mold insert the axle sleeve injection mo(u)lding; When the circular hub groove on the die body, blade groove and reinforcement groove carry out corresponding injection moulding and the axle sleeve in the circular injection molding mouth fuse, promptly adopt two moulds that separate to carry out twice injection moulding.The mould of this making plastics axial-flow leaf has solved the problem that axle sleeve that existing single mould single injection-molded exists is easy to generate contraction distortion, has novel structure, and the plastics axial-flow leaf serviceability of making is good, the intensity of axle sleeve and advantage of high precision.
Description of drawings
Fig. 1: the structural representation of die body among the embodiment of the utility model.
Fig. 2: the structural representation of the embodiment axis cover die of the utility model.
The specific embodiment
With Fig. 2 the specific embodiment of the utility model is done a detailed explanation below in conjunction with accompanying drawing 1.
A kind of mould of making the plastics axial-flow leaf as depicted in figs. 1 and 2 is made up of die body 1 and axle sleeve mould 2, and die body 1 is provided with circular hub groove 14, blade groove 11 and reinforcement groove 12, and blade groove 11 is 3.
The circle centre position of circular hub groove 14 is provided with the circular injection molding mouth 13 of placing axle sleeve on the die body 1, and circular injection molding mouth 13 is connected with circular hub groove 14 and reinforcement groove 12.Be provided with axle sleeve forming cavity 21 in the axle sleeve mould 2, the shape of axle sleeve forming cavity 21 is corresponding with circular injection molding mouth 13 couplings.
During injection moulding; Earlier through the axle sleeve forming cavity 21 in the axle sleeve mould 2 with the axle sleeve injection mo(u)lding; Then the axle sleeve of moulding is put into the circular injection molding mouth 13 on the die body 1 as mold insert; Again the circular hub groove 14 on the die body, blade groove 11 and reinforcement groove 12 are carried out the one injection moulding, the axle sleeve during injection moulding in circular hub groove and reinforcement and the circular injection molding mouth fuses, and promptly adopts two moulds that separate to carry out twice injection moulding and makes whole axial-flow leaf moulding; Solved the axle sleeve wall thickness too thick with circular hub, reinforcement and the blade problem of the easy contraction distortion of injection moulding axle sleeve simultaneously; The axis hole precision of axle sleeve also can be guaranteed, and the production qualification rate of product is risen, and has also improved product quality and serviceability.
Claims (2)
1. mould of making the plastics axial-flow leaf; It is characterized in that constituting by die body and axle sleeve mould; Die body is provided with circular hub groove, blade groove and reinforcement groove; The circle centre position of circular hub groove is provided with the circular injection molding mouth of placing axle sleeve on the die body, and the circular injection molding mouth is connected with circular hub groove and reinforcement groove; Be provided with the axle sleeve forming cavity in the axle sleeve mould, the shape of axle sleeve forming cavity is corresponding with circular injection molding mouth coupling.
