Abstract
The utility model relates to a mould for manufacturing a middle section of a cross-flow fan blade, which comprises a mould frame and an inner mold core, wherein the inner mold core is provided with a circular-ring-shaped wheel disc groove; a blade molding die body is arranged at the edge of the inner side of the wheel disc groove; the blade molding die body is internally provided with a blade molding cavity; and the blade molding die body is formed by splicing a plurality of mould blocks. The mould for manufacturing the middle section of the cross-flow fan blade has the advantages that the structure is novel, the polishing treatment can be carried out on a molded part, and the accuracy and the production efficiency of products are improved.
Description
Technical field
The utility model relates to the processing mold that saves in the through-flow fan blade.
Background technology
Through-flow fan blade processes by saving ultrasonic bonding in a plurality of, and middle joint is made up of circular wheel disc and the injection moulding of polylith blade one.The mould that saves in the existing making is made up of with inner mould core framed, and inner mould core is provided with the wheel disc groove of annular, and the forming cavity of blade cuts formation on inner mould core.The blade that saves in the through-flow fan blade approaches and grows; Thickness is about 1mm; Highly be about 75mm; So polishing can't be carried out in the forming cavity surface of blade after processing, restricted the precision and the injection moulding production efficiency of mould, the forming cavity of the blade that simultaneously cutting forms on inner mould core efficient and precision when the demoulding is also low.
Summary of the invention
The purpose of the utility model is in order to solve the above-mentioned deficiency that the processing that saves in the existing through-flow fan blade exists, to improve a kind of novel structure, and that can improve product precision and production efficiency a kind ofly is used for making the mould that through-flow fan blade saves.
In order to realize above-mentioned purpose, the technical scheme below the utility model has adopted:
A kind ofly be used for making the mould that through-flow fan blade saves; Framed and inner mould core, inner mould core is provided with the wheel disc groove of annular, and the inside edge of said wheel disc groove is provided with the blade forming die body; Be provided with the blade forming chamber in the blade forming die body, said blade forming die body is spliced to form by the polylith die piece.
As preferably, said blade forming die body is 31-35 regularly arranged along the inside edge of wheel disc groove.
That has adopted above-mentioned technical scheme a kind ofly is used for making the mould that through-flow fan blade saves; Blade forming is accomplished by the blade forming die body that the polylith die piece is spliced to form; The polylith die piece can splice and dismantle, the moulding position the blade of type can carry out sufficient polishing, improved mould and die accuracy and injection moulding production efficiency; Solved the problem of the long demoulding difficulty of blade simultaneously; Die piece can be changed, and avoids the blade local damage need change the situation of whole inner mould core, practices thrift maintenance cost and time.In sum, the mould advantage that saves in this making through-flow fan blade is a novel structure, can carry out polishing to the moulding position, has improved the precision and the production efficiency of product.
Description of drawings
The structural representation of the embodiment of Fig. 1 the utility model.
The specific embodiment
Below in conjunction with Fig. 1 the specific embodiment of the utility model is done a detailed explanation.
A kind of mould that through-flow fan blade saves that is used for making as shown in Figure 1 is made up of framed 1, inner mould core 2 and blade forming die body 4.Inner mould core 2 is located on framed 1; Inner mould core 2 is provided with the wheel disc groove 3 of annular; Blade forming die body 4 is 31-35 regularly arranged along the inside edge of wheel disc groove 3, is provided with blade forming chamber 5 in the blade forming die body 4, and blade forming die body 4 is spliced to form by polylith die piece 6.Blade forming is accomplished by blade forming die body 4; The forming cavity that the has substituted existing blade structure that directly cutting forms on inner mould core, die piece 6 can splice and dismantle, the moulding position the blade of type can carry out sufficient polishing; Mould and die accuracy and injection moulding production efficiency have been improved; Solved the problem of the long demoulding difficulty of blade simultaneously, die piece 6 also can be changed, and avoids the blade local damage need change the situation of whole inner mould core 2.
