Abstract

The utility model discloses a kind of mould for die-casting automobile damper support ring, it comprises a main sprue (1) and many secondary sprues (2), the entrance of the secondary sprue (2) of every bar is all communicated with main sprue (1), the outlet of the secondary sprue (2) of every bar is communicated with annular die cavity (3), every two secondary sprues (2) are one group, with two the secondary sprues (2) organized along main sprue (1) symmetrical distribution; The length of many groups of secondary sprues (2) is successively decreased from the near to the remote gradually from the entrance of main sprue (1); The length direction of the secondary sprue (2) of every bar and consistent with the tangential direction of the annular die cavity (3) that this secondary sprue (2) connects.This mould can ensure each annular die cavity (3) isostasy, make quality of finished product good, qualification rate high.

Description

For the mould of die-casting automobile damper support ring
Technical field
The utility model relates to edge knurling machine, is specifically a kind of mould for die-casting automobile damper support ring.
Background technology
In automobile absorber, support ring is generally shaping by die casting, the mould for die-casting automobile damper support ring of prior art comprise a main sprue and many isometric along the symmetrical secondary sprue of main sprue, the entrance of the secondary sprue of every bar is all communicated with main sprue, the outlet of the secondary sprue of every bar is communicated with an annular die cavity, the length direction of each secondary sprue is just right with corresponding annular die cavity, that is, the center of circle of annular die cavity is positioned on the extended line of width bisector of secondary sprue.
There is following defect in the mould for die-casting automobile damper support ring of prior art: first, for each annular die cavity, the length of its running channel is the summation of main running channel length and secondary running channel length, like this, large from the short pressure of annular die cavity running channel total length close to main running channel entrance and cast gate, little from the long pressure of annular die cavity running channel total length away from main running channel entrance, therefore cause the pressure of each annular die cavity inconsistent, the excessive insufficient pressure had of some pressure, finally make the quality of the support ring with batch die cast uneven, qualification rate is low; And, because secondary sprue casting liquid out can fling the inner periphery sidewall of annular die cavity, produce bubble, reduce the quality of product further.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of isostasy, the mould for die-casting automobile damper support ring that makes quality of finished product good, qualification rate high that can ensure each annular die cavity.
Technical solution of the present utility model is, a kind of mould for die-casting automobile damper support ring with following structure is provided, it comprises a main sprue and many secondary sprues, the entrance of the secondary sprue of every bar is all communicated with main sprue, the outlet of the secondary sprue of every bar is communicated with annular die cavity, every two secondary sprues are one group, with two the secondary sprues organized along the symmetrical distribution of main sprue; The length of many groups of secondary sprues is successively decreased from the near to the remote gradually from the entrance of main sprue; The length direction of the secondary sprue of every bar and consistent with the tangential direction of the annular die cavity that this secondary sprue connects.
After adopting above structure, the utility model is used for the mould of die-casting automobile damper support ring compared with prior art, has the following advantages:
Shorten gradually because the length organizing secondary sprue increases along with the distance with main sprue more, therefore for single annular die cavity, short and the secondary sprue of main sprue of the annular die cavity entered from the entrance of main sprue is long, long and the secondary sprue of main sprue from the annular die cavity away from main sprue is short, like this, the running channel total length of each annular die cavity is all equal, the pressure that each annular die cavity is subject to is also consistent, avoid the die casting pressure of each annular die cavity uneven, and then guarantee that quality of finished is consistent, improve qualification rate; And, due to the length direction of the secondary sprue of every bar and consistent with the tangential direction of the annular die cavity that this secondary sprue connects, like this, cast liquid from secondary sprue export go out after can not to liquidate the inner periphery sidewall of annular die cavity, avoid producing bubble, improve the qualification rate of the quality of product further.
As preferably, main sprue end is provided with arc-shaped edges, and like this, the impact produced when casting liquid flows to main sprue end is smaller, can reduce bubble and turbulent flow, makes the flowing of casting liquid more smooth-going.
Accompanying drawing explanation
Fig. 1 is the plan structure schematic diagram of the utility model for the mould of die-casting automobile damper support ring.
Shown in figure 1, main sprue, 2, secondary sprue, 3, annular die cavity, 4, rising head, 5, arc-shaped edges.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the utility model is used for the mould of die-casting automobile damper support ring, and it comprises a main sprue 1 and many secondary sprues 2.Main sprue 1 end is provided with arc-shaped edges 5.The entrance of the secondary sprue 2 of every bar is all communicated with main sprue 1, and the outlet of the secondary sprue 2 of every bar is communicated with annular die cavity 3.Every two secondary sprues 2 are one group, with two the secondary sprues 2 organized along the symmetrical distribution of main sprue 1; That is, the length of two secondary sprues 2 of same group is equal, also equal with the angle between main sprue 1, but direction is contrary.The length of many groups of secondary sprues 2 is successively decreased from the near to the remote gradually from the entrance of main sprue 1; That is, from main sprue 1 entrance more close to the length of one group two secondary sprues 2 longer, and from main sprue 1 entrance more away from the length of one group two secondary sprues 2 shorter.The length direction of the secondary sprue 2 of every bar and consistent with the tangential direction of the annular die cavity 3 that this secondary sprue 2 connects.
Each annular die cavity 3 is provided with a rising head 4, and the position of rising head 4 is positioned at the close beneath of each secondary sprue 2 outlet, and like this, casting liquid revolves the last just arrival rising head 4 that turns around after annular die cavity 3 is poured in secondary sprue 2 outlet, can reduce bubble, also be convenient to slagging-off.

Claims (2)
