Determine between sleeve 15 and spacing collar 11, when limiting plate 14 is reached and is resisted against 15 side of fixes sleeve, you can limitation is pushed
Further moving horizontally for bar 13, ensures that the eject position that shower nozzle 16 is eventually arrived at overlaps with the inwall in drag chamber 7, that is, push
Bar 13 is engaged the horizontal throw that can control push rod 13 with fixes sleeve 15, so that the horizontal-extending position of precise control shower nozzle 16
Put.
The horizontal direction projected length L3 of push rod 902 is inclined in the present embodiment more than the outer wall of lower mould 6 to drag chamber 7
Inwall apart from L1 (distance of the upper outer wall of mould 4 to the inwall of upper model cavity 5 is also L1)；Incline the vertical direction projection of push rod 902
Length L4 goes up the lower surface of mould 4 to the vertical distance L2 of the upper surface of shower nozzle 16 when being more than mould original state, as shown in Figure 3 and Figure 6,
Ensure during the entire process of die sinking/matched moulds, shower nozzle 16 can smoothly reach/exit mold cavity location, and avoid shower nozzle 16 with
Contact wear between 4/ time mould of upper mould 6, and during shower nozzle 16 is moved horizontally, roller 10 connects with inclination push rod 902 all the time
Touch, inclining the pair roller 10 of push rod 902 carries out effectively promoting and stopping positioning, the steady movement of shower nozzle 16 is ensured, wherein inclination is pushed away
The structure of bar 902 can use single segment structure as shown in Figure 6.
When the present embodiment is actually used, under original state (non-matched moulds state, such as Fig. 1), power spring 12 is in compression shape
State, and the compressible length of power spring 12 is more than the outer wall of lower mould 6 to the inwall of drag chamber 7 apart from L1, it is now spacing
Plate 14 is stuck in the side of fixes sleeve 15 limitation shower nozzle 16 further to extension in die cavity, the floor projection of shower nozzle 16 inner side and drag
The inwall in chamber 7 overlaps, and roller 10 is in contact with the least significant end for inclining push rod 902, and roller 10 away from mold cavity side and
The distance between the distance between fixes sleeve 15, limiting plate 14 and spacing collar 11 are all higher than the outer wall of lower mould 6 to drag chamber 7
Inwall apart from L1；Gradually matched moulds is moved down upper mould 4, is inclined push rod 902 and is gradually moved down therewith, inclines push rod 902 and the phase of roller 10
Coordinate, roller 10 incline push rod 902 extruding under gradually moved horizontally to the direction away from mold cavity, i.e., push rod 13 by
Power spring 12 is gradually extruded, shower nozzle 16 is moved to the direction away from mold cavity, shower nozzle 16 is withdrawn into mould 4 with
Outside mould 6, as shown in Fig. 2 it should be noted that during matched moulds, with reference to Fig. 3 and Fig. 4, being pushed away when roller 10 moves to inclination
When at the position A of bar 902, it is L5 (L5 is less than L3) to incline push rod 902 in the floor projection length of A, and vertical projection is highly L6,
When L5 is equal with L1, i.e., the horizontal displacement of shower nozzle 16 and the lower outer wall of mould 6 to the inwall of drag chamber 7 apart from L1 it is equal when, L6
The lower surface of mould 4 to the vertical distance L2 of the upper surface of shower nozzle 16 is gone up when being then less than original state, i.e., when the horizontal level of shower nozzle 16 has been moved back
When going out outside mould, upper mould 4 do not drop to shower nozzle 16 yet where vertical height position, ensure during the entire process of matched moulds, keep away
Exempt from the lower surface of upper mould 4 to be contacted with shower nozzle 16 and hinder the horizontal movement of shower nozzle 16, shower nozzle 16 is smoothly exited outside mould, and keep away
Contact-free is worn and torn.
Accordingly, after the completion of forging, upper mould 4 gradually molds shifting, inclines the gradually upper shifting therewith of push rod 902, inclines
Push rod 902 is engaged with roller 10, and roller 10 is under the elastic force effect of power spring 12 gradually to relatively low the one of inclination push rod 902
End movement, i.e., push rod 13 is gradually moved horizontally to the direction near mold cavity, until limiting plate 14 is hindered by fixes sleeve 15
Gear, finally makes shower nozzle 16 extend between model cavity 5 and drag chamber 7, inner side and the drag chamber 7 of the floor projection of shower nozzle 16
Inwall overlap, return to primitive age state, as shown in figure 1, start both sides shower nozzle 16, start to mold cavity alternating spray lubricate
Agent.
The mould cooling and lubricating method carried out using the cooling and lubricating device of the present embodiment, is followed the steps below：
Step one, confirmation mould original state：Now shower nozzle 16 is extended between model cavity 5 and drag chamber 7, shower nozzle
The inner side of 16 floor projections overlaps with the inwall in drag chamber 7；
Step 2, forging is put into mold cavity；
Step 3, upper bolster 1 and upper mould 4 move down matched moulds simultaneously, incline push rod 902 and move down therewith, pushing rolling wheels 10 along
The incline direction for inclining push rod 902 is moved horizontally, and push rod 13 drives shower nozzle 16 away from mold cavity；
Step 4, forging processing；
Step 5, upper bolster 1 and upper mould 4 remove mould on simultaneously, incline push rod 902 and moved on, and roller 10 is along inclination
The incline direction of push rod 902 is moved horizontally, and push rod 13 drives shower nozzle 16 to be close to mold cavity, until the floor projection of shower nozzle 16
Inner side overlaps with the inwall in drag chamber 7；
Step 6, taking-up forging；
Step 7, the control ambilateral alternating water delivery base lubricating agent of shower nozzle 16 of mould.
The cooling and lubricating device of the present embodiment by inclining the mutual cooperation of push rod 902, roller 10 and power spring 12 etc.,
Realize and the eject position of shower nozzle 16 is automatically controlled, without artificial operation, simple structure is easy to operate, and operating efficiency is significantly
Improve, and the structure design of both sides shower nozzle 16 then further helps in abundant, the uniform injection to mold cavity, ensures cooling drop
High efficiency, the uniformity of temperature, suitably promote the use of aborning.
