In preformed hole.
Under normal circumstances, a secondary mold includes upper die holder 10 and lower die holder, and upper die holder 10 and lower die holder are mounted on press,
Press starting drives 10 downlink of upper die holder and lower die holder to mold, while binder component therein, cutter etc. add plate
Work.
In the present embodiment, upper die holder 10 is also required to be used cooperatively with lower die holder, and specifically, mold after processing is completed, is reserved
There is installation upper mold to reserve the position of material pressing core 30, it is initial in use, can not install mould reserves material pressing core 30.But to plate
Punch process is carried out, when being especially machined to the workpiece of high and low fall, since fold can be generated on workpiece, needs to install at this time
Upper mold reserves material pressing core 30.
When carrying out easy fold work pieces process, plate is placed on the lower die seat, drives 10 downlink of upper die holder, upper mold is reserved
Material pressing core 30 is contacted with plate first, and compresses easy fold position, and then upper die holder 10 continues traveling downwardly, and until bottom dead centre, is completed
The processing such as drawing.Due to being prepared with the position that installation upper mold reserves material pressing core 30, therefore, later period workpiece at design mold initial stage
When fold easily occurs, it is only necessary to upper mold be reserved material pressing core 30 and installed, corrugation problem can be solved.It avoids the need for redesigning mould
Tool, improves processing efficiency, saves a large amount of cost.
Referring to FIG. 2, further, it further includes work limited post 33 and work limit that the upper mold, which reserves material pressing core 30,
Set 34；The work limited post 33 is fixedly connected with the mounting plate 31 close to the side of the material pressing core ontology 32；The work
Make limit sleeve 34 and is fixedly connected with the material pressing core ontology 32 close to the side of the mounting plate 31；The work limited post 33 is inserted
It is connected in the work limit sleeve 34, and can be slided in the work limit sleeve 34.
With continued reference to FIG. 2, further, the first grab, the work limit are provided on the work limited post 33
The second grab is provided in set 34；When the material pressing core ontology 32 is moved to binder position along pressing direction, first card
Hook and the mutual hook card of second grab.

The detailed process for installing the reserved material pressing core 30 of upper mold is as follows:
Upper mold reserves the type face that material pressing core 30 stretches out upper die holder 10 under the action of nitrogen gas spring 35, and press drives upper die holder
When 10 downlink, the upper mold for stretching out the type face of upper die holder 10 is reserved material pressing core 30 and is first contacted with the plate for being placed on lower die holder, will rise
Wrinkle position is fixed, and then upper die holder 10 continues traveling downwardly, and the pre- material pressing core of upper mold provides pressure-plate-force after the contraction of nitrogen gas spring 35, is played
The effect of suppressing prevents the generation of corrugation problem, and upper die holder 10 continues traveling downwardly, and reaches bottom dead centre, completes deep drawing of sheet process.
Wherein, work limit sleeve 34 and work limited post 33 match, and the movement of material pressing core 30 is on the one hand reserved for upper mold
Guiding role is played, the arrival bottom dead centre of material pressing core 30 in addition can also be reserved for upper mold, position-limiting action, specially the first grab is provided
With the mutual hook card of the second grab.After processing is completed, press drives 10 uplink of upper die holder, and upper mold reserves material pressing core 30 in nitrogen gas spring
The type face that upper die holder 10 is stretched out under the action of 35, resetting locating part 37 is to provide limit after the reserved material pressing core 30 of upper mold resets to make
With, avoid upper mold reserve 30 downlink of material pressing core it is too quickly, fall off from mounting plate 31, cause unnecessary loss.
Be described in detail structure, feature and effect of the invention based on the embodiments shown in the drawings, it is above only
For presently preferred embodiments of the present invention, but the present invention does not limit the scope of implementation as shown in the drawings, all according to conception institute of the invention
