Abstract
The utility model relates to a kind of die casting seal groove structures, including the seal groove being made of the depressed section being set in mold core and model frame, sealing strip in the seal groove, the sealing strip thickness is greater than the seal groove depth, the sealing groove bottom width is greater than top width, is filled with glass cement in seal groove.After molding, sealing strip extrusion, into seal groove inclined depression part, the glass cement filled in seal groove plays the role of further sealing and fixing sealing strip.The utility model structure is simple, and easy to process and implementation can effectively improve the sealing performance of vacuum die-casting mould, avoid the problem that sealing ring is fallen in production process, guarantee mold vacuum degree, reduces product and stomata and oxide inclusion occurs, improves die-cast product quality.
Description
Technical field
The utility model relates to a kind of die casting seal groove structures, the especially seal groove structure of vacuum die-casting mould.
Background technique
Die-casting process is to make molten metal in pressure in molten metal high speed indentation precision metallic mold cavity using high pressure
The casting technique of casting is formed with lower cooled and solidified.If die casting type is intracavitary, there are air, will lead to and have gas in casting
Body can not improve casting mechanical performance by heat treatment.Vacuum sealed mold used in die-casting process at present, using tradition
Sealing means, sealing ring is easily fallen in production process, leads to the problem of poorly sealed, and type is intracavitary to enter air, and product is caused to go out
The defects of existing stomata and oxide inclusion.It is trapezoidal die casting seal groove that known utility model, which discloses a kind of cross section,
Structure has preferable sealing performance, but trapezium structure is inconvenient to process, and slot inner surface easily forms longitudinal grin tool marks, and when sealing is crowded
It is easily revealed in the case where insufficient pressure.
Utility model content
The utility model in view of the deficiencies of the prior art, proposes a kind of die casting seal groove structure, improves mold
Sealing performance, effectively avoid the problem that sealing ring is fallen in production process, reduce air enter mold.
In order to achieve the above object, the utility model uses a kind of following technical scheme: die casting seal groove structure,
Including seal groove, the sealing strip being set in die casting, it is characterised in that: the seal groove is in the mould of the die casting
Combining closely on face between core, model frame, the mold core, model frame adjacent bond face on be respectively equipped with along its horizontal integration
The wedge-shaped indentation of direction setting, the seal groove is by the two wedge-shaped indentations combination forming, and the concordant phase in two wedge-shaped indentations bottom
It connects；The bottom width of seal groove is greater than top width of rebate；The sealing strip is matched in the seal groove, and sealing strip level is convex
For the notch position of the seal groove.
Further, the sealing groove bottom is parallel with the mold core upper surface, the side inclination on mold core and model frame,
Angle with bottom surface is acute angle, and two sides junction arc transition.
Further, glass cement is filled in the seal groove.
Further, guide part is equipped at the top of the groove side wall.
Further, the sealing sliver transvers section is circle.
In conclusion the utility model structure is simple, easy to process and implementation can effectively improve the close of vacuum die-casting mould
Sealing property avoids the problem that sealing ring is fallen in production process, guarantees mold vacuum degree, reduces product and stomata and oxidation folder occurs
Sundries improves die-cast product quality.
Detailed description of the invention
Fig. 1 is seal groove structure schematic diagram before molding.
Fig. 2 is status diagram after the molding of dynamic model cover half.
Specific embodiment
Combined with specific embodiments below and attached drawing is further described the utility model.
A kind of die casting seal groove structure as shown in Figure 1 to Figure 2, including the seal groove 2, close being set in die casting
Strip of paper used for sealing 3, it is characterised in that: the seal groove 2 is in the face of combining closely between the mold core 1 of the die casting, model frame 4
On, the mold core 1, model frame 4 adjacent bond face on be respectively equipped with along its horizontal integration direction setting wedge-shaped indentation, it is described
Seal groove 2 is by the two wedge-shaped indentations combination forming, and the two wedge-shaped indentations bottom concordantly connects；The bottom width of seal groove 2 is big
In top width of rebate；The sealing strip 3 is matched in the seal groove 2, and 3 level of sealing strip protrudes from the seal groove 2
Notch position.
Further, 2 bottom surface of seal groove is parallel with 1 upper surface of mold core, the side on mold core 1 and model frame 4
Inclination, the angle with bottom surface are acute angle, and two sides junction arc transition.
Further, glass cement is filled in the seal groove 2.
Further, 2 top side wall of seal groove is equipped with guide part 5.
Further, 3 cross section of sealing strip is circle.
As shown in Fig. 2, since sealing strip protrudes from seal groove upper surface, after molding, sealing strip is squeezed power deformation, enters
Seal groove inclined depression part, filling glass glue in seal groove further function as the effect for sealing and fixing sealing strip, guarantee work
Sealing strip is not fallen out during work.
Technical solution provided by the utility model is described in detail above, specific case pair used herein
The principle and embodiment of the utility model embodiment are expounded, and the explanation of above embodiments is only applicable to help to understand
The principle of the utility model embodiment；At the same time, for those skilled in the art, foundation the utility model embodiment,
There will be changes in specific embodiment and application range, in conclusion the content of the present specification should not be construed as to this
The limitation of utility model.
