The specific embodiment
Below in conjunction with embodiment shown in the drawings the utility model is further described.
Embodiment one: referring to accompanying drawing 1 to shown in the accompanying drawing 4.
A kind of mould with distortion square cotter ejection piece, comprise back plate 1, be arranged on the liftout attachment of back on the plate 1, be arranged on male model plate 2 on the liftout attachment, be arranged on male model benevolence 3, caster 4 in the male model plate 2, be arranged on the mother module core 5 in the caster 4, formation product die cavity 6 between male model benevolence 3 and the mother module core 5.
Liftout attachment comprises following liftout plate 11, be arranged on down upper ejector plate 12 on the liftout plate 11, be arranged on limited block 13, lower end on the upper ejector plate 12 is fixedly installed on the bottom of upper ejector plate 12 and passes through hole 7 and extend into distortion square cotter ejection piece 14 in the product die cavity 6.
The outer wall of distortion square cotter ejection piece 14 is provided with the angle of inclination T of the angle of inclination T1 on 15, the first inclined-planes 8, second inclined-plane that match with first inclined-plane 8 more than or equal to second inclined-plane 15, for example T1 〉=T+2 °.The opposite side outer wall relative with second inclined-plane 15 of distortion square cotter ejection piece 14 is provided with first groove 16, first groove 16 comprises that three inclined-plane 17, the three inclined-planes 17 identical with first inclined-plane, 8 angle of inclination T1 connect outer wall and the bottom land of first groove 16 and the upper end that the 3rd inclined-plane 17 is positioned at first groove 16 of distortion square cotter ejection piece 14.The bottom on first inclined-plane 8 is less than or equal to the depth S 1 of first groove 16, for example S1 〉=S+0.2mm to the depth S at top.
