Background technology
At present, injecting products is in injection molding process, and injecting products is after injection mold injection moulding completes, and the product after needing thimble injection moulding to be completed ejects male model, and is a bit provided with back-off due to injecting products, and then in injection moulding process, need side core-pulling mechanism.
And usually there is the situation of interference mutually in the side core-pulling mechanism of prior art and ejecting mechanism, such as, when side core-pulling is not also extracted out completely in injecting products, ejecting mechanism starts to eject injecting products, and then very easily sever thimble in the process and break side core-pulling, thus improve the incidence of injection mold security incident in injection moulding production process.
But for the deficiencies in the prior art, developer is necessary a kind of reasonable in design, structure of development simply, after moulding, when thimble ejects injecting products, the situation that there will not be thimble and side core-pulling mutually to interfere, security performance is high, cost is low, the safe ejecting mechanism for injection mold of long service life.
Utility model content
For solving prior art Problems existing, the utility model object provides a kind of reasonable in design, structure simply, after moulding, when thimble ejects injecting products, the situation that there will not be thimble and side core-pulling mutually to interfere, security performance is high, cost is low, the safe ejecting mechanism for injection mold of long service life.
For solving above technical problem, the utility model comes to be realize by the following technical solutions: a kind of safe ejecting mechanism for injection mold, comprises ejector retainner plate, thimble fixed head, thimble, safe thimble and is arranged on the side core-pulling mechanism of safe thimble upper end;
Described ejector retainner plate upper surface is provided with thimble fixed head, and thimble and safe thimble are fixed on ejector retainner plate upper surface by described thimble fixed head;
Described side core-pulling mechanism comprises side core-pulling, is arranged on the back-moving spring of side core-pulling one end and is arranged on the upside of side core-pulling, and with the briquetting that side core-pulling cooperatively interacts, described side core-pulling offers the safety vent matched with safe thimble.
Be provided with male template on the downside of described side core-pulling, between described male template and side core-pulling, be provided with back-up block.
In a preferred embodiment of the present utility model, described briquetting is fixed by bolts to the lower surface of existing caster.
In a preferred embodiment of the present utility model, described side core-pulling and briquetting are that inclined-plane coordinates.
The beneficial effects of the utility model are, compared with prior art, the utility model comprises ejector retainner plate, thimble fixed head, thimble, safe thimble and the side core-pulling mechanism being arranged on safe thimble upper end, ejector retainner plate upper surface is provided with thimble fixed head, thimble and safe thimble are fixed on ejector retainner plate upper surface by thimble fixed head, side core-pulling mechanism comprises side core-pulling, be arranged on the back-moving spring of side core-pulling one end and be arranged on the upside of side core-pulling, and the briquetting cooperatively interacted with side core-pulling, side core-pulling offers the safety vent matched with safe thimble, and then after injection moulding matched moulds completes, existing caster drives the fixing master mold in its lower end to move up, thus drive be fixed on caster lower end briquetting on move, side core-pulling moves right under the active force of back-moving spring simultaneously, when the safety vent that side core-pulling is offered moves to safe thimble present position, safe thimble and safety vent cooperatively interact, and then thimble moves up, thus injecting products is ejected male model, and then avoid side core-pulling when also not extracting out completely in injecting products, ejecting mechanism starts to eject injecting products, what cause severs thimble and the situation breaking side core-pulling, thus improve security performance and stability.
