Copper rod material or aluminium bar material, which pass through, is heated to predetermined temperature, such as copper rod material is heated to 600~900 DEG C, then leads to
The cutting that cutting equipment carries out setting length is crossed, the bar after cutting is placed into the lower mold core cavity 21 of lower mold core 5, in nature
Under state, 19 upper end of bottom knockout bar can expose the surface 1-3mm of lower mold core cavity 21, at this time support of the bar in bottom knockout bar 19
Under cannot fall completely in lower mold core cavity 21.When upper die holder 3 drives upper mold 4 and upper mold core 15 to move downward, upper mold core 15
First is contacted with compression bar 13 and continue to move downward, knockout plate 12 under compression bar 13 is moved downward and pushed under the pressure of upper mold core 15
Bottom knockout bar 19 is driven to be moved downward along inner guiding post 10 and compress lower spring 6,19 upper end of bottom knockout bar returns to down at this time
In the hole of mold core cavity 21, bar is fallen completely in the lower mold core cavity 21 of lower mold core 5.Upper mold core 15 and lower mold core 5 are closed completely
It closes, in the cavity that the first punch 26, the second punch 27 and third punch 28 are formed to upper mold core cavity 22 and lower mold core cavity 21
The heart movement to bar carry out extrusion forming, bar be extruded after in upper mold core cavity 22 and lower mold core cavity 21 and the first punch
26, the second punch 27 and third punch 28 are closed in the closed cavity formed deformation of extending, and machine the red stamping of molding.
After molding is completed, forcing press drives upper die holder 3, upper mold 4 and upper mold core 15 are whole to move upwards, upper mold core 15 with
Compression bar 13 detaches, and lower knockout plate 12 moves upwards under the elastic force of lower spring 6 and drive bottom knockout bar 19 and compression bar 13 extensive upwards
Shape is restored, during bottom knockout bar 19 moves upwards, upper end exposes the through-hole of lower mold core cavity 21 and pushes the red stamping of molding de-
Lower mold core cavity 21 from lower mold core 5 is molded red stamping and then stays in the upper mold core cavity 22 of upper mold core 15 and follow upper mold core
15 move upwards.Ejector beam 20 can will not expose upper mold core pattern in the through-hole of upper mold core 15 completely on when free state
Outside chamber 22.When upper knockout plate 2 drives ejector beam 20 downward along locating rod 17 under the thrust that forcing press makes bar 23
It moves and compresses spring 16, the surface of the upper mold core cavity 22 of upper mold core 15 is exposed in upper 20 end of knockout rod at this time, will be molded
Red stamping pushes away the upper mold core cavity 22 of upper mold core 15.After beating 23 external force of bar and disappearing, elastic force of the upper knockout plate 2 in upper spring 16
It drives upper ejector beam 20 to move upwards under effect to set back.
The multidirectional red stamping die second embodiment schematic diagram of the present invention shown in Fig. 5, Fig. 6 is please referred to, is different from the first embodiment
, lower spring 6 is not used and uses reset power of the push rod 25 as lower knockout plate 12, and copper rod material or aluminium bar material are by adding
Heat arrives predetermined temperature, such as copper rod material is heated to 600~900 DEG C, and the cutting of setting length is then carried out by cutting equipment, is cut
Bar after cutting is placed into the lower mold core cavity 21 of lower mold core 5, and bar cannot be complete under the support of bottom knockout bar 19 at this time
It falls into lower mold core cavity 21.When upper die holder 3 drives upper mold 4 and upper mold core 15 to move downward, 15 elder generation of upper mold core and compression bar 13
It contacts and continues to move downward, knockout plate 12 drives bottom knockout under compression bar 13 is moved downward and pushed under the pressure of upper mold core 15
Bar 19 moves downward along inner guiding post 10 and push rod 25 is pushed to move downward, and 19 upper end of bottom knockout bar returns to lower mold core at this time
In 5 hole, bar is fallen completely in the lower mold core cavity 21 of lower mold core 5.Upper mold core 15 and lower mold core 5 squeeze bar,
Bar is closed to extend in the closed cavity formed and deform after being extruded in upper mold core cavity 22 and lower mold core cavity 21, machines
It is molded red stamping.When bar is put into the lower mold core cavity 21 of lower mold core 5, push rod 25 can also move downward in advance, under
Knockout plate 12 drives bottom knockout bar 19 to be moved downward along inner guiding post 10 under the effect of gravity, and 19 upper end of bottom knockout bar returns to
In the hole of lower mold core 5, bar can be fallen completely in the lower mold core cavity 21 of lower mold core 5.
After molding is completed, forcing press drives upper die holder 3, upper mold 4 and upper mold core 15 are whole to move upwards, upper mold core 15 with
Compression bar 13 detaches, and lower knockout plate 12 moves upwards under the thrust of push rod 25 and drive bottom knockout bar 19 and compression bar 13 to move upwards
It restores to the original state, during bottom knockout bar 19 moves upwards, under upper end exposes the through-hole of lower mold core 5 and the red stamping of molding is pushed to be detached from
The lower mold core cavity 21 of mold core 5, be molded red stamping then stay in the upper mold core cavity 22 of upper mold core 15 and follow upper mold core 15 to
Upper movement.Upper knockout plate 2 drives ejector beam 20 to be moved downward along locating rod 17 under the thrust that forcing press makes bar 23
And upper spring 16 is compressed, the surface of upper mold core 15 is exposed in upper 17 end of knockout rod at this time, will be molded red stamping and pushes away upper mold core 15
Upper mold core cavity 22.After beating 23 external force of bar and disappearing, upper knockout plate 2 drives upper ejector beam under the elastic force effect of upper spring 16
20 move upwards and set back.
The multidirectional red stamping die 3rd embodiment schematic diagram of the present invention is please referred to shown in Fig. 7, Fig. 8, with first embodiment and the
Unlike two embodiments, it is applied in combination using lower spring 6 and push rod 25, operation principle is same as above, repeats no more.
