Description

Mechanical type is assisted ejecting mechanism
Technical field
The utility model relates to a kind of mold mechanism, particularly relates to the auxiliary ejecting mechanism of a kind of mechanical type.
Background technology
In current injection molding technology; usually can run into its appearance of some plastic products and require very high and baroque situation; and this moment; advancing glue then becomes the difficult point of mould design; to cause industry to need to require to advance glue from the cover half part (non-appearance) of mould according to properties of product; and when moulding is finished; if can't eject product by the injector push rod; because the push rod of injector is positioned at the dynamic model side; this has just determined mould to need to advance the glue side from cover half and has ejected die sinking that promptly ejecting with advancing glue is the same side.For addressing this problem, adopt oil hydraulic cylinder to assist in this type of mould usually and eject, and this structure I﹠M very bothers before this, as not being that the specification product also need accompanying drawing to order, and its degree of safety is not good enough and cost is higher.
Summary of the invention
The purpose of this utility model is that proposing a kind of mechanical type at above-mentioned defective assists ejecting mechanism.
But the auxiliary ejecting mechanism of mechanical type of the present utility model mainly comprises the fixed half and moving half of folding, and establish the auxiliary stay bolt parts that invest on both sides, and described cover half comprises the male model plate of setting up according to this, upper ejector plate, following liftout plate, gripper shoe, stripper plate and bottom plate, described dynamic model comprises and stacks upright caster and upper mounted plate mutually, wherein, described male model plate and master mold are provided with in opposite directions, and be provided with a molding space between the two, and be provided with an elastic mechanism between its male model plate and the upper ejector plate, keep existing between its male model plate and the upper ejector plate ejection stroke space with an elastic-restoring force; Described auxiliary stay bolt parts comprise pull bar and strut two parts in addition, wherein, these parts are arranged at the relative two sides of mould, its pull bar is fixed on the above-mentioned upper and lower liftout plate, and its strut is fixed on the above-mentioned caster, this strut is provided with a guide groove, and this guide groove fastens the pilot pin that is provided with on the above-mentioned pull bar just, and the ejection stroke sum in this guide groove length and described ejection stroke space can not be less than the mould opening stroke.
In the use, when the mould die sinking to a certain degree the time, its strut can the tensile force when the injector die sinking under, by pull bar upper and lower liftout plate is moved toward male model plate direction along the ejection stroke space, at this moment, being arranged at thimble on the liftout plate is about to product and ejects.And during the mould matched moulds, the male model plate then can push up back original position with upper and lower liftout plate by elastic mechanism.
So adopt the auxiliary ejecting mechanism of the mechanical type of this utility model, when having reduced cost, improved the degree of safety of equipment, its installation of aspect simultaneously and maintenance procedures.
