Description

Compression mod vertical riser parting structure and Z-shaped cast, overflowing system

Technical field

The utility model relates to technical field of mold, relates in particular to a kind of compression mod vertical riser parting structure and Z-shaped cast, overflowing system.

Background technology

At present, lateralarea more greatly, higher die casting, be all that the employing of inertia is directly poured into a mould, overflowing system, die joint is also to adopt plane formula, will consider that like this stuffing pressure being subject on mould side is large, thus on mould side, need to stay larger thickness can not produce the problem such as overlap, die deformation to ensure to produce, as depicted in figs. 1 and 2, common compression mod cast, overflowing system comprise cover half framed 11, fixed die insert 12, die casting 13, moving die insert 14, screw 15, dynamic model framed 16.Wherein, fixed die insert 12 is monoblock type, and in process of production, A place is closed, and easily produces cold shut, beats the defects of die castings such as insatiable hunger.Because fixed die insert 12 is matched in clearance with cover half framed 11, the pressure being subject at B place is that (F is that to be subject to stuffing pressure be clamp force in mould side to F=A1 × P aborning, A1 is that product lateral vertical is in the projected area of die joint, injection ratio pressure when P is die casting) see by formula, when projected area, A1 is larger, the stuffing pressure that mould side is subject to, the type that rises power are just larger, and mould is more easily distortion just, thus mould insert also corresponding also to do large.

In prior art, runner adopts directly and pours into a mould, and because die casting side is higher, and whole side encased by fixed die insert, and gas cannot normally be discharged, and the product part pressing out there will be cold shut, beats the defects of die castings such as insatiable hunger.

Summary of the invention

Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of compression mod vertical riser parting structure and Z-shaped cast, overflowing system, adopt perpendicular to the ladder of mold parting surface and Z-shaped cast, overflowing structure, mainly to offer mold parting surface with the shape of product side, again with two moving die inserts that set out with matched in clearance, ensure that bottom can exhaust.Deslagging is unwrapped to be located at and is inserted above, is beneficial to the die cast on product side.

For achieving the above object, the utility model provides a kind of compression mod vertical riser parting structure and Z-shaped cast, overflowing system, comprise that cover half is framed, the first screw, wedge block, fixed die insert, the second screw, moving die insert, die casting, moving die insert A, moving die insert B, the 3rd screw and dynamic model framed; Described fixed die insert is monoblock type, fixed die insert and cover half are framed is matched in clearance, described the 3rd screw moving die insert B be fixed on dynamic model framed on, on moving die insert B, offer deslagging bag C, between moving die insert B and moving die insert A, there is fit clearance D, wedge block be with described the first screw be fixed on cover half framed on, on moving die insert B, do an inclined-plane, in the time of matched moulds, together with the inclined-plane of wedge block closely cooperates with moving die insert B inclined-plane, thus the side stuffing pressure that moving die insert B is subject to be delivered to cover half framed on.

In preferred embodiments of the present utility model, the bevel angle of described moving die insert B is 10 °-13 °.

The utility model adopts perpendicular to the ladder of mold parting surface and Z-shaped cast, overflowing structure, shape with product side is offered mold parting surface, again with two moving die inserts that set out with matched in clearance, ensure that bottom can exhaust, deslagging is unwrapped to be located at and is inserted above, is beneficial to the die cast on product side.

Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to understand fully the purpose of this utility model, feature and effect.

Detailed description of the invention

As shown in Figure 3 and Figure 4, a kind of compression mod vertical riser parting structure and Z-shaped cast, overflowing system, comprise that cover half is framed 1, the first screw 2, wedge block 3, the second screw 4, fixed die insert 5, die casting 6, moving die insert A7, moving die insert B8, the 3rd screw 9 and dynamic model framed 10.Fixed die insert 5 is monoblock type, fixed die insert 5 is matched in clearance with cover half framed 1, the 3rd screw 9 is fixed on moving die insert B8 on dynamic model framed 10, because the die joint of moving die insert B8 is with the shape somatotype of die casting side, therefore overall die joint rises to die casting peak place, on moving die insert B8, offer deslagging bag C, the deslagging of product side peak can fully be discharged like this, has ensured to there will not be aborning cold shut, beat the defects of die castings such as insatiable hunger.

Between moving die insert B and moving die insert A, have fit clearance D, this gap D can play scavenging action aborning, ensures the quality of die casting.Consider that the stuffing pressure that side is subject to is larger, can not be in order to ensure that mould strength increases die insert, framed size.Therefore adopt compression mod vertical riser parting structure to ensure intensity on mould.In the present embodiment, on moving die insert B8, do an inclined-plane, wedge block 3 is to be fixed on cover half framed 1 with the first screw 2, in the time of matched moulds, together with the inclined-plane of wedge block 3 closely cooperates with moving die insert B8 inclined-plane, thereby the side stuffing pressure that moving die insert B8 is subject to is delivered on cover half framed 1, ensures mould strength.

Bevel angle on moving die insert B is 10 °-13 °, the stuffing pressure that moving die insert B8 is subject to aborning act on framed on, framed meeting produces micro-deformation, in the time of die casting machine pressure release, framed micro-deformation bounce-back, can produce very large enclasping force, gradient is too little, mould can not held, and gradient is too large, can increase the manufacturing cost of mould.Being 10 °-13 ° through reasonable computation gradient is desired angle.

More than describe preferred embodiment of the present utility model in detail.The ordinary skill that should be appreciated that this area just can be made many modifications and variations according to design of the present utility model without creative work.Therefore, all technical staff in the art comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in by the determined protection domain of claims.
