Abstract
The invention discloses an injection mould core for a refrigerator fan frame, and belongs to the field of injection moulds. The injection mould core comprises three needle point pouring gates, namely a needle point pouring gate 1, a needle point pouring gate 2 and a needle point pouring gate 3, wherein the needle point pouring gates have two diameter sizes; the needle point pouring gate 1 has a relatively large diameter size and is independently positioned on one side of the mould core; the diameter sizes of the needle point pouring gate 2 and the needle point pouring gate 3 are the same and are smaller than that of the needle point pouring gate 1; the needle point pouring gate 2 and the needle point pouring gate 3 are distributed on the other side of the mould core. The injection mould core has the advantages as follows: according to CAE (computer aided engineering) simulation, the three needle point pouring gates with different diameter sizes are optimally designed, and according to the maximum flow length/wall thickness, a specific pouring position is determined so as to transfer a welding mark during injection moulding production of the refrigerator fan frame from an original weak position to a relatively strong end surface, so that the development cost of the mould is greatly reduced, the product quality is improved and thus the service life of a refrigerator cooling fan is prolonged.
