Description

A kind of buffer-type die casting ingate structure

Technical field

The utility model belongs to technology of die manufacturing field, and in particular to a kind of buffer-type die casting ingate structure.

Background technology

Because die casting aluminium liquid filling type is that viscosity is higher, with Laminar Flow, have to compare liquid when design section is accumulated The sectional area of die cast metal ingate is big, and design is too small, ingate during casting die cavity underfill can be caused just to have solidified, seriously Influence casting quality.

Utility model content

Purpose of utility model：The purpose of this utility model is to solve deficiency of the prior art, there is provided one kind buffering Formula die casting ingate structure, the mobility of aluminium liquid is greatly reduced using buffering pipe so that material is no longer altered at oblique top, is thickeied Ingate thickness reduces flowing velocity of the aluminium liquid at ingate, good fluidity, working stability.

Technical scheme：A kind of buffer-type die casting ingate structure described in the utility model, including casting body and pour Mouth pipeline, the casting body and cast gate pipeline communication, the cast gate pipeline include the first pipeline, second pipe and connecting tube Road, first pipeline are connected as one with second pipe by connecting pipe transition, and first pipeline, second pipe and Connecting pipe uses integrated formed structure, and the caliber of first pipeline is more than the caliber of the second pipe, first pipe Road, second pipe and connecting pipe use ceramic structure, and the end of first pipeline is used for the end for connecting ingate, institute The end for stating second pipe is used to connect casting mold die cavity.

Further, the caliber of the cast gate pipeline is 4-6mm.

Further, first pipeline is connected with casting body.

Further, the thickness of first pipeline, second pipe and connecting pipe is 1-6mm.

Further, the caliber ratio of first pipeline and the second pipe is 1：1.5-3.

Further, the length ratio of first pipeline and the second pipe is 1：1-3.

Further, first pipeline, the thickness between second pipe and connecting pipe are equal or unequal.

Further, the cross section of first pipeline is circle, and the cross section of the second pipe is kidney ellipsoid or circle Shape.

Beneficial effect：The utility model greatly reduces aluminium liquid by being improved to original cast gate using buffering pipe Mobility so that no longer alter material at oblique top, thicken ingate thickness to reduce flowing velocity of the aluminium liquid at ingate, flow Good, the working stability of property.

Embodiment

Technical scheme is described in further detail with reference to specific embodiments and the drawings.

A kind of buffer-type die casting ingate structure as shown in Fig. 1 to Fig. 3, including casting body 1 and cast gate pipeline 2, The casting body 1 connects with cast gate pipeline 2, and the cast gate pipeline 2 includes the first pipeline 21, second pipe 23 and connecting pipe 22, first pipeline 21 is connected as one with second pipe 23 by the transition of connecting pipe 22, and first pipeline 21, the Two pipelines 23 and connecting pipe 22 use integrated formed structure, and the caliber of first pipeline 21 is more than the second pipe 23 Caliber, first pipeline 21, second pipe 23 and connecting pipe 22 use ceramic structure, the end of first pipeline 21 For connecting the end of ingate, the end of the second pipe 23 is used to connect casting mold die cavity.

Further optimization as the present embodiment：

Preferably, the caliber of the cast gate pipeline 2 is 4-6mm, and first pipeline 21 is connected with casting body 1.

Preferably, the thickness of first pipeline 21, second pipe 23 and connecting pipe 22 is 1-6mm；First pipe The caliber ratio of road 21 and the second pipe 23 is 1：1.5-3；The length ratio of first pipeline 21 and the second pipe 23 For 1：1-3.First pipeline 21, the thickness between second pipe 23 and connecting pipe 22 are equal or unequal.

Another cast gate pipeline as shown in Figure 4, its structure and said structure are essentially identical, the difference is that in the embodiment The cross section of first pipeline 21 is circle, and the cross section of the second pipe 23 is kidney ellipsoid.It can enter one using kidney ellipsoid structure Step reduces the molten metal pressure of ingate delivery port position, the area of dissipation of ingate when increase casting cools down.

The utility model greatly reduces the mobility of aluminium liquid using buffering pipe by being improved to original cast gate, So that no longer altering material at oblique top, ingate thickness is thickeied to reduce flowing velocity of the aluminium liquid at ingate, good fluidity, work It is stable.

It is described above, only it is preferred embodiment of the present utility model, not the utility model is made any formal Limitation, although the utility model is disclosed above with preferred embodiment, but be not limited to the utility model, it is any ripe Professional and technical personnel is known, is not being departed from the range of technical solutions of the utility model, when in the technology using the disclosure above Hold the equivalent embodiment made a little change or be modified to equivalent variations, as long as being without departing from technical solutions of the utility model Hold, any simple modification, equivalent change and modification made according to the technical essence of the utility model to above example, still Belong in the range of technical solutions of the utility model.
