A kind of heat of Chinese patent (publication number: CN101486063A, the patent No.: ZL 200910066588.X) is applied for
Press forming die: the disclosure of the invention a kind of hot stamping forming die, the shape of the invention combination mold working surface exist
Its internal a series of cooling groove of setting, is arranged corresponding protrusion, punch-pin and port plate combine shape on port plate
At cavity as cooling pipe, port plate and punch-pin groove both ends form cavity, are connected respectively with inlet and outlet, water from
Water inlet flows into, and by the cavity while each cooling pipe of dispensing of end, is reached by the heat exchange between cooling water and mold
Cooling purpose efficiently solves the problems, such as cooling uniformity and water channel derusting problem.
Published thesis (He Bin, is full of bright, flat high-strength steel sheet drop stamping water cooling mold design [J] recklessly, Forging equipment with
Manufacturing technology .2012, (06): 62-65.): the paper describes the selection of mold materials according to domestic and international present Research, convex, recessed
The selection of mode radius, the determination of clearance between matrix and punch, design of Cooling System requirement, the mold design such as determination of water cooled pipeline RDH are wanted
Point has directive significance to hot stamping die design.
The above patent and paper solve the problems, such as cooling uniformity, cooling efficiency, water channel derusting etc., are drop stamping
The design of mold provides foundation.At present drop stamping field there are still a series of problems, as: 1, replacing different water channel parameters
Mold needs to expend vast resources, increases experimental cost, and influence of the water channel parameter to Cooling capacity in mold still rests on emulation
Stage.2, the cooling water channel of mold and the connector of confession, outlet conduit, which often interfere, causes connector difficult to install.3, after heating
Plate is placed on blank holder it can decline rapidly with blank holder contact portion temperature, cause before punching press starts plate to have larger
Temperature drop influences
The accuracy of experimental result.
Summary of the invention
The technical problems to be solved by the present invention are: the water channel parameter of 1, mold directly affects the cooling effect of mold.

It answers and opens up punch-pin cooling water at punch-pin refrigerating module 37 and summarize chamber 40, punch-pin is set in the cavity wall that punch-pin cooling water summarizes chamber 40
Summarize chamber connection interface 41.
It in the present embodiment, forms and is machined with screw hole in each module of punch-pin, be equipped on the refrigerating module of punch-pin cold
But water channel and rectangle keyway are equipped with rectangle keyway on punch-pin cushion block, are equipped in two punch-pin summarizing modules and summarize chamber and connection
Connect mouth.Meanwhile part has carried out independent piecemeal where the cooling water channel in punch-pin, is equipped with multiple groups and there was only cooling water channel parameter
Different refrigerating modules can realize changing for mould water channel parameter by the cooling module with different cooling water channel parameters of replacement
Become, convenient for probing into influence of the different channel structures to mold cooling capacity.Meanwhile cooling water channel parameter is probed into using the mold
When influence to Cooling capacity in mold, the refrigerating module of several groups of different parameters need to be only processed, avoids the repetition processing of mold, drop
Low experimental cost.
Cooling water summarizing module is all made of in punch-pin and cavity plate in the present embodiment in drop stamping experiment mould to each convex
Cooling water channel on mould piecemeal and cavity plate piecemeal has carried out central water supply and water outlet summarizes, and passes through the connection interface in summarizing module
It is connected with water-in and water-out pipeline, reduces the connector number of mold and water circulation system, solve water supply line and mold cooling water
Connector excessive bring connector in road, which interferes, or spacing is too small is difficult to the problem of installing.Meanwhile the cavity of set summarizing module
The water channel that can satisfy all refrigerating modules being equipped with to the mold supply water and water flow summarizes, so that the mold only needs to be equipped with
One group of summarizing module and no replacement is required when replacing refrigerating module summarizing module.
The present embodiment drop stamping experiment mould can realize the fast velocity modulation of cooling water channel parameter by the replacement of local module
It is whole, save the cost for remanufacturing mold.By using the cooling with different cooling water channel parameters on symmetrical position
Module can be convenient and quickly complete comparative experiments.The mold is provided with quick change construction, can efficiently complete refrigerating module
Replacement, has saved test period.The present invention, which summarizes cooling water piecemeal, to be flowed in or out, and be can solve pipe joint and is excessively brought
Connector interfere or spacing is too small is difficult to the problem of installing.In addition, present invention employs be provided with spring on blank holder
Plunger prevents plate before shaping from building motion is contacted and will not influence with blank holder, can effectively solve plate before the punching
There is the problem of biggish temperature decline in the region contacted with blank holder.
Part that the present invention does not relate to is the same as those in the prior art or can be realized by using the prior art.
As described above, must not be explained although the present invention has been indicated and described referring to specific preferred embodiment
For the limitation to invention itself.It without prejudice to the spirit and scope of the invention as defined in the appended claims, can be right
Various changes can be made in the form and details for it.
