Abstract
The utility model provides a mould structure of anti-shrinkage cavity oil leak, neutron die carrier front portion installation neutron die core, install the pressurization round pin of slope between neutron die carrier and the neutron die core, neutron die carrier rear portion is equipped with the template, connect through second neutron connecting plate between template and the neutron die carrier, be connected through first neutron connecting plate between pressurization round pin and the second neutron connecting plate, neutron die core, neutron die carrier and inside being located pressurization round pin, first neutron connecting plate and the second neutron connecting plate top are run through and are equipped with oblique water hole. The utility model discloses a prevent mould structure of shrinkage cavity oil leak adds an oblique water hole through the position that produces at the shrinkage cavity, avoids the mould back article to realize the cooling effect, reduced the bad probability of shrinkage cavity, improve the product yields.
Description
Technical Field
The utility model relates to a casting mould technical field.
Background
After the CVT250 CASE casting die is machined in a DYPT mode, shrinkage cavities penetrate from I4 threaded holes and the material surface of the root portion of the pressurizing pin to cause leakage, through tissue analysis, the edges of the shrinkage cavities are irregular, the shrinkage cavity is not spherical, the CVT250 CASE casting die is judged to be mainly shrinkage cavities, and leakage is caused by penetration of the shrinkage cavities; the model temperature corresponding to each batch of cast products I4 is not found to have large fluctuation between 170 and 180 degrees, and the position is added as a model temperature control point. The periphery of the part is provided with an oblique pressurizing pin, so that additional vertical internal cooling cannot be realized.
Disclosure of Invention
In order to solve the problem that the shrinkage cavity runs through and reveals in the current casting mould, the utility model provides a prevent mould structure of shrinkage cavity oil leak.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the utility model provides a mould structure of anti-shrinkage cavity oil leak, neutron die carrier front portion installation neutron die core, install the pressurization round pin of slope between neutron die carrier and the neutron die core, neutron die carrier rear portion is equipped with the template, connect through second neutron connecting plate between template and the neutron die carrier, be connected through first neutron connecting plate between pressurization round pin and the second neutron connecting plate, neutron die core, neutron die carrier and inside being located pressurization round pin, first neutron connecting plate and the second neutron connecting plate top are run through and are equipped with oblique water hole.
And a third neutron connecting plate is arranged at the rear part of the second neutron connecting plate.
And a limiting plate is arranged inside the neutron die carrier and positioned outside the inclined water hole.
The utility model discloses a prevent mould structure of shrinkage cavity oil leak adds an oblique water hole through the position that produces at the shrinkage cavity, avoids the mould back article to realize the cooling effect, reduced the bad probability of shrinkage cavity, improve the product yields.
Drawings
Fig. 1 is the utility model discloses prevent the mould structure of shrinkage cavity oil leak.
In the figure: 1. neutron mold core, 2, neutron die carrier, 3, limiting plate, 4, template, 5, oblique water hole, 6, pressure pin, 7, first neutron connecting plate, 8, second neutron connecting plate, 9, third neutron connecting plate.
Detailed Description
The utility model discloses a mould structure of anti-shrinkage hole oil leak is shown in fig. 1, neutron die carrier 2 front portion installation neutron die core 1, the pressurization round pin 6 of installation slope between neutron die carrier 2 and the neutron die core 1, 2 rear portions of neutron die carrier are equipped with template 4, connect through second neutron connecting plate 8 between template 4 and the neutron die carrier 3, be connected through first neutron connecting plate 7 between pressurization round pin 6 and the second neutron connecting plate 7, neutron die core 1, neutron die carrier 2 and 4 inside pressurization round pins 6 that are located of template, first neutron connecting plate 7 and second neutron connecting plate 8 top are run through and are equipped with oblique water hole 5, second neutron connecting plate 8 rear portion is equipped with third neutron connecting plate 9, 2 inside oblique water holes 5 outsides that are located of neutron die carrier are equipped with limiting plate 3.
In order to reduce the shrinkage cavity occurrence rate, internal cooling is added to a shrinkage cavity generation part, the temperature of a die is reduced, aluminum liquid is solidified more quickly, thermal stress concentration is improved, shrinkage cavity is prevented from being generated due to uneven shrinkage caused by thermal stress concentration during aluminum liquid solidification, and thus the shrinkage cavity occurrence rate is reduced. The periphery of the part is provided with the pressurizing pin 6 in the oblique direction, so that the vertical internal cooling cannot be realized, and an oblique water hole is designed to avoid the rear part of the die, thereby realizing the cooling function.
