Background technology
Powder metallurgy is to take metal dust or made with metal dust (or mixture of metal dust and non-metal powder)
For raw material, through shaping and sintering, produce the industrial technology of metal material, composite and all kinds product；And metal
Powder injection-molded is the forming technique quickly growing at present, has can form arbitrarily complicated shape small-sized zero
Part, and the good advantage of product each position density uniformity, this technology is to mix fine metal dust with binding agent, is delivered to
In Plasticized component, it is heated in Plasticized component and changes into molten state, the molten metal of molten state is pushed by the thrust by screw rod
To the front end of barrel, in the front end of barrel is sprayed by nozzle to the die cavity of mould, after cured sizing, obtain moulded products, its
Operation principle is similar to the syringe having an injection, but metal dust is placed in the air inevitably in surface attachment moisture
And dampness, if not doing corresponding process for moisture and dampness, inherently affect the performance of moulded products.
The patent of invention of Authorization Notice No. cn 103464761 b discloses a kind of injection molding machine hot air type dried feed
Bucket device, this device discloses air blowing heating device, hopper and balancing weight unit, and wherein balancing weight unit is used for instrumentality
The outflow of material, air blowing heating device is dried dehumidifying to the material flowing out, and this device can remove attachment in raw material automatically
Moisture and dampness, structure is simple and convenient to operate, and substantially increases work efficiency；But aerator air-supply passage and material discharging
Mouthful in same position, when the material after to drying is collected, if aerator is continuously in initial state and can lead
Cause the material after processing to be dispelled, so each collection material is required for closing aerator, so operate cumbersome, and
The service life of impact aerator.
Content of the invention
The present invention is in order to solve during material collection aerator shutoff operation trouble and affect aerator and use the longevity back and forth
A kind of life, there is provided powder metallurgy drying device.
In order to achieve the above object, the base case of the present invention provides a kind of powder metallurgy drying device, including hopper, weight
