The utility model provides a built-in reverse redrawing type backform mechanism of injection machine, comprising a push-out oil cylinder and a movable moulding board; the push-out oil cylinder is directly connected with the movable moulding board; the movable moulding board applied in the above built-in reverse redrawing type backform mechanism can directly connect with the push-out oil cylinder without the push rod. The utility model has a reasonable structure, the intensity of the movable moulding board is strengthened, and the stress on the movable moulding board is even, so that the movable moulding board is seldom deformed; during the procedure of injection, no material over flows out from the mold cavity, therefore, the mould has long life span; the utility model also has the advantages of long push-out stroke, thus, the longer(higher) products is facilitated to be processed, so that the utility model has a great applicability; the utility model has a simple structure, easy manufacture and assemble; and the utility model is suitable in the variable injection moulding machines and has a relative wider applicability range and greater market prospect.
Description
Technical field
The utility model relates to a kind of injection machine mold pushing mechanism, built-in anti-pull-type mold pushing mechanism of particularly a kind of injection machine and moving platen thereof.
Background technology
The mold pushing mechanism that is provided with on injection machine is used for ejecting the shaped article of injection mold, existing injection machine mold pushing mechanism generally adopts the push type structure, this push type mold pushing mechanism as shown in Figure 1, it ejects oil cylinder 1 and is connected with moving platen 3 by pull bar 2, the distance that ejects between oil cylinder 1 and the moving platen 3 is far away, thereby required pull bar 2 length are longer; The mold pushing mechanism of this version is because moving platen 3 is subjected to the active force influence that pull bar 2 is comparatively concentrated, produce the effect consequence of amount of deflection big (being that deflection is big) easily because intensity is little, rigidity is low, cause also producing bigger distortion A with the composition surface of the mould 4 of its binding, make the die cavity flash of mould 4, thereby influence the quality and the service life that reaches mould of injecting products; On the other hand, because it is far away apart from moving platen 3 to eject oil cylinder 1, so the length of the extended moving platen 3 of its piston rod 1-1 is shorter relatively, that is it is shorter to eject the backform stroke of oil cylinder 1, be unfavorable for producing the product of growing (or higher) (because of its required backform stroke longer).
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of rational in infrastructure, be easy to process and assemble, can improve the built-in anti-pull-type mold pushing mechanism of injection machine of die life.
Another purpose of the present utility model is to provide a kind of moving platen that is applied to the built-in anti-pull-type mold pushing mechanism of above-mentioned injection machine.
The purpose of this utility model is achieved through the following technical solutions: the built-in anti-pull-type mold pushing mechanism of this injection machine comprises and ejects oil cylinder, moving platen; it is characterized in that ejecting oil cylinder and directly be connected, cylinder lever connecting rod need be set ejecting between oil cylinder and the moving platen with moving platen.
The end face that the described connected mode that ejects oil cylinder and moving platen is specially the end face that ejects oil cylinder and moving platen fits and is bolted to connection.
The described connected mode that ejects oil cylinder and moving platen also can be and ejects oil cylinder and stretch in the moving platen chamber and with the template chamber and be bolted to connection.
A kind of moving platen that is applied to the built-in anti-pull-type mold pushing mechanism of above-mentioned injection machine does not need by pull bar directly and ejects oil cylinder and be connected.
Described moving platen middle part has is convenient to eject the template chamber that oil cylinder stretches into, and the outer face in described template chamber is provided with the built-in installing hole that ejects.
Described moving platen middle part has the template chamber, is provided with cascaded surface in the template chamber, and cascaded surface is provided with the built-in installing hole that ejects, and is used for and ejects oil cylinder being connected and installed.
The utility model has following advantage and effect with respect to prior art: (1) is rational in infrastructure; This built-in anti-pull-type mold pushing mechanism eject oil cylinder and moving platen directly is fitted and connected, the intensity of having avoided existing mold pushing mechanism to exist is little, rigidity is low, the big defectives such as (deflection are big) of amount of deflection, can strengthen the intensity of moving platen, make that moving platen is stressed evenly, distortion is little, can not produce the phenomenon of die cavity flash at injection moulding process, and can prolong the service life of mould; (2) ejection stroke is long; The oil cylinder that ejects of this built-in anti-pull-type mold pushing mechanism is connected in the end face or chamber of moving platen, so the length of the extended moving platen of its piston rod is longer, promptly its stroke is bigger, can conveniently process the product of growing (height), and applicability is good; (3) this built-in anti-pull-type mold pushing mechanism compact conformation, institute takes up space less, so adopt the injection machine complete machine structure of this mechanism can design compactly, volume is less; (4) this built-in anti-pull-type mold pushing mechanism is simple in structure, is easy to processing, assembling, and applicable to various injection moulding machines, range of application is wider, good market prospect.
