[specific embodiment]
See also Fig. 2, shown in Figure 3, automatic shearing gate mechanism in mould of the present invention is applied in mould, and this mould comprises: upper mounted plate 100, caster 110, male model plate 120, bottom plate 130 and foot pad 140, when mould matched moulds state, in this mould, the automatic shearing gate mechanism comprises:
Oil hydraulic cylinder 200, it is located at the mould both sides and is screwed with the ambilateral foot pad 140 of above-mentioned mould and is connected;
The first liftout plate 300, it is located at above-mentioned bottom plate 130 tops, and this first liftout plate 300 comprises the first upper ejector plate 310 and first time liftout plate 320, and is fixed with thimble with ejecting product 700 on this first liftout plate 300;
The second liftout plate 400, it is located at above-mentioned the first liftout plate 300 tops, this second liftout plate 400 is connected with above-mentioned oil hydraulic cylinder 200, this second liftout plate 400 comprises the second upper ejector plate 410 and second time liftout plate 420, this oil hydraulic cylinder 200 drives this second liftout plate 400 and ejects and return, and this second liftout plate 400 and 120 of above-mentioned male model plates are provided with empty avoiding, and the vertical range of this empty avoiding is greater than the thickness of cast gate 710;
Cast gate is cut pin 600, and the one end is located in above-mentioned the second liftout plate 400, and the other end contacts with cast gate 710, and cast gate is cut this end and cast gate 710 form fit that pin 600 contacts with cast gate 710, and this cast gate 710 can be side gate or bridging type cast gate etc.;
When product 700 pressurize after ejection formation in mould, start simultaneously oil hydraulic cylinder 200, the second liftout plates 400 and do under the induced effect of oil hydraulic cylinder 200 and eject action, namely the second liftout plate 400 moves upward, and the first liftout plate 300 is static; Cast gate is cut pin 600 and is moved upward under the effect of the second liftout plate 400, and because product 700 and cast gate 710 are in the condition of high temperature, cast gate is cut pin 600 and headed on cast gate 710 and separate with product 700; When moving to the second liftout plate 400 and contact with male model plate 120, eject for the first time release, due to the vertical range of empty avoiding between the second liftout plate 400 and male model plate 120 thickness greater than cast gate 710, after therefore ejection stroke finishes for the first time, cast gate 710 is cut off fully with product 700.
After cast gate 710 and product 700 were cut off fully, oil hydraulic cylinder 200 drives the second liftout plate 400 and cast gate is cut pin 600 returns, and namely the second liftout plate 400 moves downward, until complete return.
After product 700 is cooling in mould, male model plate 120 and caster 110 die sinkings of mould, under the effect of mold machine table push rod, the first liftout plate 300 upwards ejects motion, and product thimble ejects product 700 under the effect of the first liftout plate 300; Then cast gate 710 and product 700 are taken out.
Compared to prior art, automatic shearing gate mechanism in mould of the present invention, carry out ejecting for twice, eject under the drive of oil hydraulic cylinder 200 for the first time cast gate 710 is separated with product 700, then ejecting product 700 for the second time under the effect of mold machine table push rod, need not to do to cut after product 700 ejects and cut action, saved manpower and equipment cost, and product 700 and cutting of cast gate 710 to cut the place more attractive in appearance.
