Block moves down, and the movable block of lower section moves up, and under the action of diamond shape frame, two hinged installation BOB(beginning of block)s are to the left and to the right
Mobile, hinged mounting blocks push push rod, and push rod pushes demoulding push plate, and demoulding push plate starts to push test specimen in mould sleeve, de-
Under the promotion of mould push plate, the test specimen in mould sleeve is ejected to test specimen groove.
