Abstract
The utility model discloses a kind of impeller forming die, including upper die forming plate and lower mold forming plate, upper die forming plate is provided with the first recess being consistent with wheel disc upper surface, charging aperture is provided with first recess central area, lower mold forming plate is provided with the second recess being consistent with wheel disc lower surface, the center of second recess is provided with the locating dowel to raise up, and the downward depression in many places forms blade type chamber on the second recess, and wheel disc die cavity is formed after the first recess and the second recess matched moulds.The first recess that upper die forming plate of the present utility model is set can form the upper surface of wheel disc, and the second recess that lower mold forming plate is set can form the lower surface of wheel disc, set blade die cavity to be molded the blade on wheel disc in the second recess.Before injection, wheel shaft is inserted in locating dowel, with wheel disc, guide pillar integrated injection molding.The impeller performance being molded by the utility model is more preferable, and bonding strength is higher.
Description
Technical field
Injection mold field is the utility model is related to, more particularly, to a kind of impeller forming die.
Background technology
Impeller is the main part in blower fan, is as shown in Figure 1 a blade wheel structure, and the impeller includes wheel disc 111, leaf
Piece 112, wheel shaft 113 and guide pillar 114, wheel disc 111 are provided with some stomatas.The method that prior art manufactures the impeller is by wheel disc
111st, blade 112, guide pillar 114 are processed respectively, then again by three by weld, be bonded, rivet the methods of form it into one
Individual entirety, and appropriate reinforcement solutions are carried out in three junction.By impeller made of methods described, its use wheel disc 111,
Due to not being global formation between blade 112, guide pillar 114, but existing interlaminar shear strength between three is purely relied on,
Its adhesive surface is relatively weak, therefore impeller overall performance is poor, bonding strength is low, is easy to disengage damage in operation, also exists several
The shortcomings that what precision is not high, the problem of so as to cause fan efficiency low.Therefore, technical staff develop it is a can be by interior wheel disc
111st, blade 112,111 integrally formed injection mold of wheel disc.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of impeller forming die, is intended to go out by the mould molding
Performance is higher, the more preferable impeller of bonding strength.
Technical scheme is used by the utility model solves above-mentioned technical problem：A kind of impeller forming die, including it is upper
Mold forming plate and lower mold forming plate, described upper die forming plate are provided with the first recess for being consistent with wheel disc upper surface, and described the
Charging aperture is provided with one recess central area, described lower mold forming plate is provided with the second recess being consistent with wheel disc lower surface, institute
The center for the second recess stated is provided with the locating dowel to raise up, and the downward depression in many places forms leaf on the second described recess
Wheel disc die cavity is formed after piece die cavity, the first described recess and the second recess matched moulds.
Further being improved as the utility model, the first described recess is provided with multiple forming units in fan ring-type,
Described multiple forming units are set around described charging aperture, and one of forming unit is provided with and is used to place guide pillar edge
The guide hole of part, the groove for forming sheave surface reinforcement is provided between adjacent two forming units.
Further improved as the utility model, some be centered around around locating dowel is additionally provided with the second described recess
Columnar structures, described columnar structures be used for wheel disc stomata shaping.
Compared with prior art, the first recess set the utility model has the advantage of upper die forming plate can form wheel
The upper surface of disk, the second recess that lower mold forming plate is set can form the lower surface of wheel disc, blade type set in the second recess
Chamber can be molded the blade on wheel disc.Before injection, wheel shaft is inserted in locating dowel, guide pillar mold insert is put into guide hole, guide pillar edge
Part, wheel shaft and wheel disc integrated injection molding.The impeller performance being molded by the utility model is more preferable, and bonding strength is higher.

As shown in Figures 1 to 4：A kind of impeller forming die, including upper die forming plate 1 and lower mold forming plate 2, upper die forming
Plate 1 is provided with the first recess 3 being consistent with the upper surface of wheel disc 111, and charging aperture 4, lower mold forming are provided with the central area of the first recess 3
Plate 2 is provided with the second recess 5 being consistent with the lower surface of wheel disc 111, and the center of the second recess 5 is provided with the locating dowel to raise up
6, depression forms blade type chamber 7 downwards for many places on the second recess 5, and wheel type is formed after the first recess 3 and the matched moulds of the second recess 5
Chamber.
First recess 3 is provided with multiple forming units 8 in fan ring-type, and multiple forming units 8 are set around charging aperture 4,
And one of forming unit 8 is provided with the guide hole 9 for being used for placing guide pillar mold insert 114, is set between adjacent two forming units
Have to form the groove 10 of the surface reinforcement 116 of wheel disc 111.
Some columnar structures 11 being centered around around locating dowel 6 are additionally provided with second recess 5, columnar structures are used for wheel disc
The shaping of 111 stomatas 115.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
