Description
Technical field
The utility model relates to mould applications, particularly relates to a kind of large-scale frame series products injection moulding palletizing die sequential mold opening structure.
Background technology
What the die sinking mode of existing large-scale frame series products injection moulding laminated mould all adopted is synchronous die sinking, and simultaneously each die joint namely in laminated mould carries out a point modulo operation; But synchronous die sinking action all needs to rely on special synchronous mold-opening mechanism to realize, as adopted the synchronous point mode structure of gear type; But the structure of synchronous parting mechanism is more complicated usually, die cost is higher, and reliability is low.
Utility model content
The technical problem that the utility model solves is to provide simple, the lower-cost mould structure realizing large-scale frame series products injection moulding laminated mould sequential mold opening of a kind of structure.
The utility model solves the technical scheme that its technical problem adopts: large-scale frame series products injection moulding palletizing die sequential mold opening structure, comprises intermediate plate and is positioned at the first punch and second punch of intermediate plate both sides; Contact surface between described intermediate plate and the first punch is the first die joint, and the contact surface between intermediate plate and the second punch is the second die joint; Elasticity jacking block is provided with between the first die joint; Shutter is provided with between the second die joint.
Further: described elasticity jacking block comprises mounting screw, spring and jacking block; The die joint side of the first punch is provided with the mounting groove for installing elasticity jacking block; By mounting screw, spring and jacking block are arranged in mounting groove; When matched moulds, the surface of jacking block flushes with the die joint of the first punch; When parting, the surface of jacking block exceeds the die joint of the first punch; Described shutter is bearing pin, is fixedly mounted on the die joint side of the second punch by mounting screw by bearing pin, is provided with the pilot hole with bearing pin interference fit on intermediate plate simultaneously.
Further: between the first die joint, be provided with many group elasticity jacking blocks; Be provided with between the second die joint and organize shutter more.
The beneficial effects of the utility model are: by arranging elastic top block structure between the first die joint, provide power-assisted by elasticity jacking block for the parting of the first die joint, reduce the external force needed for the first die joint parting.And by arranging shutter structure between the second die joint, the parting being the second die joint by shutter provides resistance, increases the external force needed for the second die joint parting.Like this, increasing external force needed for the second die joint parting simultaneously, achieving when actual parting by reducing external force needed for the first die joint parting, the parting of the first die joint and the second die joint has dividing of sequencing.In addition, the structure of elasticity jacking block and shutter is all very simple, and easy for installation; Therefore the utility model achieves the sequential mold opening achieving large-scale frame series products injection moulding laminated mould under the prerequisite not increasing labyrinth, can cancel special synchronous mold-opening mechanism simultaneously, reduce die cost, enhance the practicality of palletizing die.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Figures 1 to 5, large-scale frame series products injection moulding palletizing die sequential mold opening structure described in the utility model, comprises intermediate plate 1 and the first punch 2 and the second punch 3 being positioned at intermediate plate 1 both sides; Contact surface between described intermediate plate 1 and the first punch 2 is the first die joint 4, and the contact surface between intermediate plate 1 and the second punch 3 is the second die joint 5; Elasticity jacking block 6 is provided with between the first die joint 4; Shutter 7 is provided with between the second die joint 5.
Wherein the effect of elasticity jacking block 6 provides elastic force for during the first die joint 4 parting, reduces external force needed for the first die joint 4 parting; And shutter 7 effect is for providing resistance during the second die joint 5 parting, increase external force needed for the second die joint 5 parting.Increase by one like this and one to subtract, make external force needed for the first die joint 4 and the second die joint 5 parting there is larger gap, finally realize the first die joint 4 and the second die joint 5 exists sequencing when parting, realize the sequential mold opening effect of laminated mould.Wherein, external force needed for so-called parting, refers to the parting pulling force that board provides for whole mould, namely during parting, and pulling force when dynamic model is return.
In addition, the concrete structure of elasticity jacking block 6 can be comprise mounting screw 81, spring 61 and jacking block 62; Die joint 21 side of the first punch 2 is provided with the mounting groove 22 for installing elasticity jacking block 6; By mounting screw 81, spring 61 and jacking block 62 are arranged in mounting groove 22; When matched moulds, the surface 621 of jacking block 62 flushes with the die joint 21 of the first punch 2; When parting, the surface 621 of jacking block 62 exceeds the die joint 21 of the first punch 2.Like this, when matched moulds, spring 61 is compressed, and jacking block 62 moves back as in mounting groove 22, and the matched moulds of whole elasticity jacking block 6 to the first die joint 4 does not have materially affect.But, when the first die joint 4 parting, compressed due to before spring 61, therefore can produce elastic force between the first die joint 4, and then reduce external force needed for the first die joint 4 parting.
In addition, the concrete structure of shutter 7 can be comprise bearing pin 71, is fixedly mounted on die joint 31 side of the second punch 3 by mounting screw 82 by bearing pin 71 simultaneously, is provided with the pilot hole 11 with bearing pin 71 interference fit on intermediate plate 1 simultaneously.Like this, when matched moulds, bearing pin 71 extend in pilot hole 11, does not have materially affect to the matched moulds of the second die joint 5.But, when the second die joint 5 parting, because bearing pin 71 and pilot hole 11 are interference fit, therefore can produce resistance between the second die joint 5, and then add external force needed for the second die joint 5 parting.
In addition, the elasticity jacking block 6 arranged between the first die joint 4 can have many groups, as arranged four groups; The shutter 7 in like manner arranged between the second die joint 5 also can have many groups, as arranged four groups.
In addition, under the utility model is still based upon a primary condition, namely when not arranging elasticity jacking block 6 and shutter 7, needed for the first die joint 4 and the second die joint 5 parting, external force should be roughly equal.Certainly, the laminated mould under actual conditions also meets such requirement substantially.
Further illustrate below and of the present utility modelly realize principle: suppose that the first die joint 4 is identical with the required total power of the second die joint 5 parting, and size is F; The elastic force that elasticity jacking block 6 provides is f1; The drag size that shutter 7 provides is f2; So during the first die joint 4 parting, reality also needs the external force size provided to be F-f1; Second die joint 5 parting is the external force size that reality also needs to provide is then F+f2.Final structure be exactly the first die joint 4 and the second die joint 5 also need board to provide external force between exist a difference, and the size of this difference is f1+f2, also just because of this difference of existence, the first die joint 4 and the second die joint 5 is just made can to realize point modulo operation of sequencing.
