Description
Technical field
The utility model is related to extrusion equipment technical field, especially a kind of oil pump case double mould cavity extrusion die.
Background technology
Cold extrusion is exactly that metal blank is placed in cold extrusion die cavity, at room temperature, passes through fixed punch-pin on forcing press
Apply pressure to blank, metal blank is made to generate plastic deformation and the processing method of obtained part.And in the process of this extruding
In, the shape and surplus of blank are the main problem for causing extrusion process pressure to block, and extruding difficulty are increased, simultaneously because hair
Training surplus is excessive to squeeze difficulty greatly to increase the rate of wear for squeezing grinding tool, shortens the service life of mold.
Utility model content
In order to overcome the shortcomings of that existing extrusion die moulding pressure mold easy to wear greatly, the utility model provide one kind
Oil pump case double mould cavity extrusion die sets two die cavitys on cavity plate, carries out roughing extruding to embryo material and finishing squeezes.
Technical solution adopted by the utility model to solve its technical problems is：A kind of oil pump case double mould cavity extrusion die
Tool, including footstock, pedestal and guide post, are fixedly connected between footstock and pedestal by guide post, and pedestal is equipped with cavity plate, one He of punch-pin
Convex mould base one is fixed on by push-rod assembly one on footstock, and punch-pin two and convex mould base two are fixed on footstock by push-rod assembly two
On, punch-pin one is placed in cavity plate upper end, and punch-pin one is arranged in convex mould base one, and punch-pin two is placed in cavity plate upper end, and punch-pin two is arranged in
In convex mould base two.
Further, including cavity plate is equipped with left mould chamber and right mould chamber.
Further, including left mould chamber cavity volume is more than right mould chamber cavity volume.
Further, including push-rod assembly one is fixed on footstock with push-rod assembly two and the two length is identical.
Further, including push-rod assembly one includes one push rod of one push rod of punch-pin and convex mould base, and the push-rod assembly two wraps
Include two push rod of two push rod of punch-pin and convex mould base.
The utility model has the beneficial effects that a kind of oil pump case double mould cavity extrusion die of the utility model, in cavity plate
On set two die cavitys, to embryo material carry out roughing extruding and finishing squeeze, alleviate the squeeze pressure of extrusion die, reduce
The rate of wear of extrusion die, to play the role of extending Life of Die for Extruding Aluminium Alloy.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
1. footstock in figure, 2. pedestals, 3. guide posts, 4. cavity plates, 5. punch-pin one, 6. convex mould bases one, 7. push-rod assemblies one, 8. is convex
Mould two, 9. convex mould bases two, 10. push-rod assemblies two, 11. left mould chambers, 12. right mould chambers, 13. punch-pin, one push rod, 14. convex mould bases one push away
Bar, 15. punch-pin, two push rod, 16. convex mould base, two push rod.
Specific implementation mode
If Fig. 1 is the structural schematic diagram of the utility model, a kind of oil pump case double mould cavity extrusion die, including footstock 1, bottom
Seat 2 and guide post 3, is fixedly connected between footstock 1 and pedestal 2 by guide post 3, and the pedestal 2 is equipped with cavity plate 4, punch-pin 1 and convex
Die holder 1 is fixed on by push-rod assembly 1 on footstock 1, and punch-pin 28 and convex mould base 29 are fixed on by push-rod assembly 2 10
On footstock 1, punch-pin 1 is placed in 4 upper end of cavity plate, and punch-pin 1 is arranged in convex mould base 1, and punch-pin 28 is placed in 4 upper end of cavity plate, convex
Mould 28 is arranged in convex mould base 29.
As shown in Figure 1, cavity plate 4 is equipped with left mould chamber 11 and right mould chamber 12.11 cavity volume of left mould chamber is more than right mould chamber 12
Cavity volume.
As shown in Figure 1, push-rod assembly 1 and push-rod assembly 2 10 are fixed on footstock 1 and the two length is identical.Push rod group
Part 1 includes one push rod 14 of one push rod 13 of punch-pin and convex mould base, and the push-rod assembly 2 10 includes two push rod 15 of punch-pin and punch-pin
Two push rods 16 of seat.
In use, putting original embryo material into left mould chamber 11, one 6 pairs of punch-pin 1 and convex mould base are pushed by push-rod assembly 1
Original embryo material is slightly squeezed, and puts right mould chamber 12 into after the one-pass molding embryo material of thick extrusion forming is taken out, while in left mould chamber
11 are placed again into original embryo material, this moment, while controlling push-rod assembly 1 and the promotion of push-rod assembly 2 10 punch-pin 1, convex mould base one
