Description

A kind of powder metallurgy injection moulding cooling pin
Technical field
The utility model relates to a kind of pin, refers to a kind of cooling pin be applied in powder metallurgy injection moulding process especially.
Background technology
As everyone knows, metal dust injection molding technology be utilize mould can injection mo(u)lding feature and manufacture the constitutional detail of high density, high accuracy, three-dimensional complex shapes fast by sintering, fast and accurately design philosophy can be turned materially the product with a fixed structure, functional characteristic, and can directly mass-produce part product.Metal dust injection molding technology not only has the advantages such as conventional powder metallurgical technique process is few, nothing is cut, economic benefit is high, but also overcome that material in traditional handicraft is uneven, mechanical performance is low, not easily forming thin-walled shortcoming, be particularly suitable for producing in enormous quantities small-sized, complicated and there is the metal parts of particular/special requirement.
The requirement of metal dust injection molding technology to mold cools down is more special, in general metal dust injection forming mold, all extra cooling system can be set in order to meet this particular/special requirement, but this type of cooling also can strengthen the structural complexity of mould while that not only cooling effect being bad, and this is the major defect for prior art.
Utility model content
Technical solution adopted in the utility model is: a kind of powder metallurgy injection moulding cooling pin, and it is embedded in mold, and when concrete enforcement, this powder metallurgy injection moulding cooling pin is embedded in the lower mold body of this mold.
Cooling water channel is provided with in this mold, this powder metallurgy injection moulding cooling pin and this cooling water channel intersect, when specific works, cooling water circulates in this cooling water channel tentatively lowers the temperature to this mold, meanwhile, because this powder metallurgy injection moulding cooling pin intersects with this cooling water channel, and this powder metallurgy injection moulding cooling pin is embedded in this mold, so deep temperature reduction can be carried out by this powder metallurgy injection moulding cooling pin to this mold, to promote cooling-down effect, when concrete enforcement, as required some this powder metallurgy injection moulding cooling pin orders can be embedded in this mold.
This powder metallurgy injection moulding cooling pin comprises embedded body, lower embedded body and water flow grooves, wherein, on this, embedded body and this lower embedded body are separately positioned on the two ends up and down of this water flow grooves, in this water flow grooves, scrobicular ring is located on the outer surface of this powder metallurgy injection moulding cooling pin, this water flow grooves is connected with this cooling water channel, embedded body and this lower embedded body offer seal groove respectively for this, sealing ring correspondence is arranged in sealing groove, and the inner surface by two sealing circles, this water flow grooves crosses water cavity around formation one.
When specific works, the cooling water in this cooling water channel crosses water cavity through some this successively, also significantly can reduce the temperature of this mold while lowering the temperature to some this powder metallurgy injection moulding cooling pins.
When concrete enforcement, this powder metallurgy injection moulding cooling pin in also offer centre hole, this centre hole run through from top to bottom be arranged on this powder metallurgy injection moulding cooling pin in, be equipped with thimble in this centre hole, when work, product stripping can be facilitated by this thimble pushing work.
The beneficial effects of the utility model are: the utility model is when work, cooling water circulates in this cooling water channel tentatively lowers the temperature to this mold, meanwhile, because this powder metallurgy injection moulding cooling pin intersects with this cooling water channel, and this powder metallurgy injection moulding cooling pin is embedded in this mold, so deep temperature reduction can be carried out to this mold, to promote cooling-down effect by this powder metallurgy injection moulding cooling pin.
Accompanying drawing explanation
Fig. 1 is that the utility model is embedded the structural representation in mold.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the structural representation of the utility model and cooling water channel.
Detailed description of the invention
As shown in Figures 1 to 3, a kind of powder metallurgy injection moulding cooling pin, it is embedded in mold 10, and when concrete enforcement, this powder metallurgy injection moulding cooling pin is embedded in the lower mold body of this mold 10.
Be provided with cooling water channel 20 in this mold 10, this powder metallurgy injection moulding cooling pin and this cooling water channel 20 intersect.
When specific works, cooling water circulates in this cooling water channel 20 tentatively lowers the temperature to this mold 10, meanwhile, because this powder metallurgy injection moulding cooling pin intersects with this cooling water channel 20, and this powder metallurgy injection moulding cooling pin is embedded in this mold 10, so deep temperature reduction can be carried out, to promote cooling-down effect by this powder metallurgy injection moulding cooling pin to this mold 10.
When concrete enforcement, can as required some this powder metallurgy injection moulding cooling pin orders be embedded in this mold 10.
This powder metallurgy injection moulding cooling pin comprises embedded body 31, lower embedded body 32 and water flow grooves 33, and wherein, on this, embedded body 31 and this lower embedded body 32 are separately positioned on the two ends up and down of this water flow grooves 33.
In this water flow grooves 33, scrobicular ring is located on the outer surface of this powder metallurgy injection moulding cooling pin, and this water flow grooves 33 is connected with this cooling water channel 20.
Embedded body 31 and this lower embedded body 32 offer seal groove respectively for this, and sealing ring 34 correspondence is arranged in sealing groove.
Inner surface by two sealing circles 34, this water flow grooves 33 crosses water cavity 35 around formation one.
When specific works, the cooling water in this cooling water channel 20 crosses water cavity 35 through some this successively, also significantly can reduce the temperature of this mold 10 while lowering the temperature to some this powder metallurgy injection moulding cooling pins.
When concrete enforcement, also offer centre hole 41 in this powder metallurgy injection moulding cooling pin, this centre hole 41 runs through from top to bottom and is arranged in this powder metallurgy injection moulding cooling pin.
Thimble 42 is equipped with in this centre hole 41.
When work, product 100 demoulding can be facilitated by this thimble 42 pushing work.
