Abstract

The utility model discloses a die with a floating die core, which comprises a fixed die, a movable die, an auxiliary plate, a floating die core, an elastic component, an upper ejector plate, a lower ejector plate, at least one ejector pin, a plurality of ejector plate return springs and a pull rod. The fixed die and the movable die are oppositely arranged, and the movable die is provided with a die cavity. The floating die core is movably clamped in the die cavity and jointly forms a cavity with the fixed die and the movable die during die assembly. The auxiliary plate is fixed below the fixed die. The elastic component is arranged between the auxiliary plate and the floating die core. The ejector pin is fixedly arranged on the upper ejector plate and the lower ejector plate. The ejector plate return springs are pressed between the auxiliary plate and the two ejector plates. The pull rod is provided with a clamp block and is movably clamped on the two ejector plates. When the die with the floating die core is used for knockout, the product can be knocked out step by step through the matching of the floating die core with the elastic component and the ejector pin, so that the molding quality of the product is ensured.

Description

The mould of the unsteady die of tool

Technical field

The utility model relates to a kind of mould, relates in particular to the mould of the unsteady die of a kind of tool.

Background technology

See also Fig. 5, it is the partial schematic diagram of a kind of existing mold when the product 100 of demoulding deep hole position: product 100 takes shape in die joint, and this product 100 has the peviform structure, and darker at the bottom of the basin; During the demoulding, male model 20 separates with master mold 10, and product thimble 30 ejects product 100.

Yet, when above-mentioned existing mold carries out the demoulding to this product 100, because the power of pullling that mould and product 100 contact-making surfaces are big thereby product 100 is produced is just big, add that position, product 100 moulding hole is darker, be easy to cause product 100 distortion or cracking, thereby can't guarantee the Forming Quality of product 100.

The utility model content

The specific embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

See also Fig. 1, the float mould of die of the utility model tool comprises a cover half 10, a dynamic model 20, an accessory plate 30, float die 40, an elastic component, a upper ejector plate 61, once liftout plate 62, two thimbles 70, some liftout plate return springs 80 and a pull bar 90; Wherein, in the present embodiment, this elastic component is a spring 50.

Dynamic model 20 is oppositely arranged with cover half 10, and this dynamic model 20 has a die cavity 21, and this die cavity 21 comprises that a upper mould cave 211 reaches die cavity 212, is protruding with retaining and holds portion 22 between upper mould cave 211 and the following die cavity 212.

Accessory plate 30 is fixed in dynamic model 20 belows, and this accessory plate 30 offers a containing hole 31.

The die 40 that floats is fastened in the die cavity 21 movably, and this unsteady die 40 has base portion of holding 41 and forming part 42, and during matched moulds, this forming part 42 stretches in the upper mould cave 211 and dynamic model 20 and cover half 10 one common peripheral forming cavities (figure does not show).

Spring 50 places in the containing hole 31 and is resisted against die 40 bottoms of floating.

Liftout plate 62 can be in male model 20 underside under upper ejector plate 61 reached.

Thimble 70 1 ends are fixed between the upper and

lower liftout plate

61,62, and the other end passes spring 50 can extend into die cavity.

This liftout plate return spring 80 comprises a fixed bar 81 and a return elastic component 82, and these fixed bar 81 1 ends can pass dynamic model 20, and the other end is fixed on the upper and

lower liftout plate

61,62; This return elastic component 82 be sheathed on the fixed bar 81 and be resisted against accessory plate 30 and upper ejector plate 61 and following liftout plate 62 between.

Pull bar 90 has a fixture block 91, and these pull bar 90 1 ends pass upper and

lower liftout plate

61,62 and spring 50 and are fixed on the die 40 that floats, and fixture block 91 is fastened on the upper and

lower liftout plate

61,62 and makes pull bar 90 can restricted ground movable.

See also Fig. 1, during the mould matched moulds, under the elastic force effect of liftout plate return spring 80, upper and

lower liftout plate

61,62 moves down, two

liftout plates

61,62 are fastened in fixture block 91, drive pull bar 90 and the unsteady 40 times pressing springs 50 of die of pulling, and the die 40 that floats at last is positioned at die cavity 212 bottoms down; Product 100 takes shape in die joint, and thimble 70 is resisted against product 100 bottoms.

See also Fig. 2 and Fig. 3, during the mould die sinking, cover half 10 separates up and down with dynamic model 20, and spring 50 upwards flicks the die 40 that floats, and realization product 100 outer surfaces separate with upper mould cave 211; When the base portion 41 that holds of the die 40 that floats is fastened in retaining when holding portion 22, the die 40 that floats stops to eject, this moment upper ejector plate 61 and down liftout plate 62 continue to move up, drive thimble 70 product 100 ejected the die 40 that floats.

After this upper and

lower liftout plate

61,62 is downward return under the elastic force effect of liftout plate return spring 80, drives thimble 70, pull bar 90 simultaneously and die 40 return (as Fig. 4) successively that floats, thereby begins a new mould production.

As mentioned above, the mould of the unsteady die of the utility model tool is when production has the product 100 of deep hole position, can flick the die 40 that floats by spring 50 earlier, and product 100 outer surfaces are separated with die cavity 21, continue to eject that product 100 inner surfaces are separated with unsteady die 40 again by thimble 70, thereby make the product 100 smooth demouldings and guarantee the quality of production.
