Connect mouth.Meanwhile part has carried out independent piecemeal where the cooling water channel in punch-pin, multigroup only cooling water channel parameter is equipped with
Different refrigerating modules, changing for mould water channel parameter can be realized by changing module of the cooling with different cooling water channel parameters
Become, be easy to probe into influence of the different channel structures to mould cooling capacity.Meanwhile cooling water channel parameter is probed into using the mould
During 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 mould, drop
Low experimental cost.
Using cooling water summarizing module to each convex in punch-pin and cavity plate in the present embodiment in drop stamping experiment mould
Cooling water channel on mould piecemeal and cavity plate piecemeal has carried out central water supply and water outlet collects, and passes through UNICOM's interface in summarizing module
It is connected with water-in and water-out pipeline, reduces the joint number of mould and water circulation system, solve water supply line and mold cooling water
The joint that road joint is excessively brought interfere or spacing it is too small be difficult to installation the problem of.Meanwhile the cavity of set summarizing module
It disclosure satisfy that the water channel for all refrigerating modules being equipped with to the mould is supplied water and current collect so that the mould only needs to be equipped with
One group of summarizing module and it need not change summarizing module when changing refrigerating module.
The present embodiment drop stamping experiment mould, the fast velocity modulation of cooling water channel parameter can be realized by the replacing of local module
It is whole, save the cost for remanufacturing mould.By using the cooling with different cooling water channel parameters on symmetrical position
Module, it can conveniently and efficiently complete contrast experiment.The mould is provided with quick change construction, can efficiently complete refrigerating module
Replace, saved test period.The utility model, which collects cooling water piecemeal, to be flowed in or out, and it is excessive can to solve pipe joint
The joint brought interfere or spacing it is too small be difficult to installation the problem of.Set in addition, the utility model employs on blank holder
Spring-loaded plunger has been put, has prevented that plate contacts with blank holder and do not interfere with building motion before shaping, and can effectively solve in punching press
There is the problem of larger Wen Duxiajiang in the region that plate contacts with blank holder before.
The utility model is not directed to partly same as the prior art or can realized using prior art.
As described above, although the utility model has been represented and described with reference to specific preferred embodiment, but it must not
It is construed to the limitation to the utility model itself.In the spirit and scope of the present utility model for not departing from appended claims and defining
Under the premise of, can various changes can be made in the form and details to it.
