Description
Technical Field
The utility model relates to a powder injection molding mould field, in particular to metal powder injection moulding concave cam mould of many caves of a heat engine mouth mould.
Background
Metal powder injection molding (MIM) is a new molding technique that has been rapidly developed in recent years, and has advantages in that it is possible to mold small parts having a complicated arbitrary shape, and the density of each part of the product is uniform, and the performance is excellent. The metal powder and the organic binder are uniformly mixed into a mixture with fluidity, the mixture is injected into a mold cavity with the shape of a part by an advanced injection machine, and the part is highly densified by a binder removal technology and sintering, wherein one of the key processes is to obtain a specific shape by using the mold. The concave-convex wheel has special structural characteristics, namely a through hole is arranged in the middle of the circular outer body. When designing a mold, in order to improve the yield, when designing the mold as one mold with a plurality of cavities, the mold manufactured in this way is subjected to powder injection molding, which may have fatal defects: when the number of the holes of the die is large, the feeding fluidity is poor, and cold materials are easy to cause. Injection defects such as weld marks, short shots, shrinkage, etc. may occur at the far side of the gate and the inner wall of the through hole. The production efficiency of the product is low, the product quality is unstable, and the rejection rate is high.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome prior art's defect, provide a metal powder injection moulding concave cam mould of many caves of heat engine mouth one mould.
The utility model provides a following technical scheme:
the utility model provides a metal powder injection moulding concave cam mould in many caves of heat engine mouth one mould, including heating machine mouth, cover half and movable mould, the movable mould is pressed and is covered and install in the top of cover half, the movable mould surface is provided with movable mould benevolence, the cover half surface is provided with cover half mould benevolence, all be provided with 16 die cavities on movable mould benevolence and the cover half mould benevolence, be linked together through the sprue between 16 die cavities, the inside of cover half is provided with the heating machine mouth.
As a preferred technical scheme of the utility model, a tip connection of heater mouth has the heating interface, and the heating interface sets up in the cover half casing outside, the other end of heater mouth is linked together through sprue and die cavity.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the glue feeding mode in the device is changed from a traditional main runner and branch runner connecting product into a main runner straight connecting product, so that poor injection such as poor product fusion and insufficient glue flushing can be better solved; the runner design adopts the design of a main runner direct connection product, so that the glue feeding amount of each cavity of the mold is uniform, and the density and the single weight stability of an injection blank are ensured.
