Description
Technical field
The utility model relates to the injection moulding field, relates in particular to a kind of upside-down mounting mould.
Background technology
For existing upside-down mounting mould, because product is stayed solid plate one side when die sinking, do not connect ejecting mechanism in solid plate one side, so, generally be to eject product by increasing structures such as oil cylinder, when die sinking, active and inactive mold is opened earlier, provide a signal to the oil cylinder that is contained on the front mould from injection machine then, oil cylinder drives ejector retainner plate and ejects; During matched moulds, injection machine provides signal to oil cylinder, and oil cylinder drives ejector retainner plate and resets moving mold matched moulds, injection moulding.
There is following defective in existing upside-down mounting mould:
1, special mechanisms such as oil cylinder need be set, also control corresponding circuit, complex structure need be set;
2, because special-purpose control circuit is set, be unfavorable for the maintenance of mould.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of upside-down mounting mould is provided, and the utility model is simple in structure, maintains easily.
Its technical scheme is as follows:
A kind of upside-down mounting mould, comprise moving platen, solid plate, thimble, thimble panel, Ejector Retainer Plate, bottom plate, holder, form die cavity between moving platen and the solid plate, the thimble panel is connected with Ejector Retainer Plate, thimble passes top nail panel and towards die cavity, holder is connected with solid plate; Also include pull bar, limited block, voussoir, first spring and second spring, the stiff end of pull bar be connected with moving platen, the free end of pull bar is provided with the end step, limited block is movably connected on the thimble panel, first spring is located between limited block and the thimble panel, voussoir is movably connected on the Ejector Retainer Plate, second spring is located between voussoir and the Ejector Retainer Plate, the end step of pull bar matches with the end of limited block, between holder and limited block, be provided with the cammed surface that matches, between bottom plate and voussoir, be provided with the lozenges that matches.
The technical scheme of the further refinement of aforementioned techniques scheme can be:
Described bottom plate is provided with the wedge groove, and described lozenges is located on this wedge groove.
The end step of described pull bar protrudes to thimble panel one side.
The end face of the end step of described pull bar is the plane.
Described voussoir is the outer end near an end of described pull bar, and this outer end is the plane.
Described limited block is the outer end near an end of described pull bar, and protrude and the formation step with respect to opposite side near a side of described solid plate this outer end; This step matches with the end step of described pull bar.
Described limited block, voussoir are two, and be corresponding, and described pull bar, holder also are two, and pull bar, holder lay respectively at the both sides of described solid plate.
The injection moulding process of present embodiment is:
After injection moulding was finished, moving platen retreated.The pull bar that is fixed on the moving platen both sides is along with moving platen retreats together.Behind the slow astern segment distance, the end step of pull bar contacts with limited block on the thimble panel, drives limited block with back stay by the end step and retreats, and then drive the thimble panel and Ejector Retainer Plate retreats together.At this moment, voussoir is deviate from the wedge groove of bottom plate, and its end is supported by the end face of tie rod end step, Ejector Retainer Plate promotes the push rod motion, realization ejects the action of product, pull bar continues pulling thimble panel and Ejector Retainer Plate retreats, when limited block touches holder, because the effect of cammed surface, limited block retreats to the motion of first spring, crosses limited block until the tie rod end step, when tie rod end step end face is crossed the end of voussoir, under the active force of spring, voussoir is deviate from the wedge groove of bottom plate, stretches out the edge of Ejector Retainer Plate.
After taking out product, moving platen advances, prepare matched moulds, drive pull bar and advance together, the end step of pull bar promotes voussoir outstanding on the Ejector Retainer Plate, promoting thimble panel and Ejector Retainer Plate retreats together, voussoir is got back to by the top in the wedge groove of bottom plate, because the effect of lozenges, second spring is compressed, mould resets, and enters injection moulding next time.
In sum, the utility model has the advantages that: realize advancing of thimble panel and Ejector Retainer Plate and retreat that save original oil cylinder and control circuit, structure is simpler, and is easy to maintenance by parts such as pull bar, limited block, voussoirs.
