Mouthful cross sectional shape is simple, and convenient use personnel carry out follow-up Precision Machining, passes through the first cast gate and the second cast gate here
Section, which is set, effectively realizes above-mentioned effect.
Preferably, first die cavity, the second die cavity are standard impact specimen die cavity.
Using such scheme, here by the way that the first die cavity, the second die cavity are arranged into standard impact specimen die cavity, use
Personnel's more standard when being tested, effectively improve the precision of experiment.
Preferably, the cavity plate is respectively arranged with opening in four corner positions, the cavity plate is opened in close
The position of mouth is provided with screwed hole.
Using such scheme, here by four screwed holes be arranged on save material while, moreover it is possible to effectively realize plus
Curable type cavity plate.
In summary, the utility model has the advantages that：Here the non-notch on the first die cavity and are passed through
Setting jaggy can be realized on two die cavities carries out different types of test on a batten mould, facilitates entering for test
OK, and reduce cost.
