Abstract
The utility model discloses a sealed vacuum die-casting mold which comprises a stationary mold, a movable mold and an ejection mechanism arranged on the movable mold, wherein the stationary mold and the movable mold are closed to form a cavity and an overflow groove; the cavity is communicated with the overflow groove; two seal rings are arranged outside a mold joint of the stationary mold and the movable mold; an air pumping groove is further formed between the two seal rings; grooves are formed in both the stationary mold and the movable mold; the grooves become air exhaust grooves after the stationary mold and the movable mold are closed; and two ends of each air exhaust groove are communicated with the overflow groove and the air pumping groove respectively. According to the sealed vacuum die-casting mold, the seal rings are arranged outside the mold joint of the stationary mold and the movable mold, air exhaust grooves and the air pumping groove are arranged and communicated to a vacuumizer, so that air in the cavity can be exhausted timely and effectively, and the mold has the advantages of good exhaust effect, low cost, simple structure and the like.
Description
Technical field
The utility model relates to a kind of compression mod, particularly a kind of sealed vacuum compression mod.
Background technology
Die casting is a kind of method of casting liquid forging, a kind of technology of finishing at the die casting die forging machine of special use.Its basic craft course is: molten metal elder generation's low speed or high-speed casting fill in the die cavity of type progressive die tool, mould has movable cavity surface, it is along with the cooling procedure pressurization of molten metal is forged, both eliminated the shrinkage porosity defect of contraction cavity of blank, also make the interior tissue of blank reach the broken crystal grain of forging attitude, the comprehensive mechanical performance of blank is significantly improved.
In the press casting procedure of thicker products such as aluminium alloy, cause product pore to occur owing to there being gas in the die cavity, be the common problem of press casting procedure, therefore, in press casting procedure, how effectively to discharge the gas in the die cavity, become the problem of needing solution badly.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of sealed vacuum compression mod, and bubble appears in product in the press casting procedure to avoid.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of sealed vacuum compression mod, comprise cover half, dynamic model, and be arranged on the ejecting mechanism on the described dynamic model, form die cavity and overflow launder after described cover half and the dynamic model closure, described die cavity is communicated with overflow launder, and the die joint arranged outside of described cover half and dynamic model has two circle sealing rings;
Also be provided with the groove of bleeding between the described sealing ring of two circles;
Be provided with groove on the described fixed half and moving half, described groove forms air discharge duct after described cover half and the dynamic model closure, and the two ends of described air discharge duct are communicated with described overflow launder and the groove of bleeding respectively.
Preferably, described air discharge duct is one or more of.
Preferably, described air discharge duct is zigzag.
Preferably, described compression mod is provided with the vacuum adapter that is communicated with bleed groove and evacuator.
Pass through technique scheme, the sealed vacuum compression mod that the utility model provides, it passes through the arranged outside sealing ring at the die joint of fixed half and moving half, and air discharge duct is set and the groove of bleeding is communicated on the evacuator, can be in time, effectively the gas in the die cavity is drained, have advantages such as good exhaust effect, cost are low, simple structure.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use is done to introduce simply in will describing embodiment below.
Fig. 1 is the structural representation of the disclosed a kind of sealed vacuum compression mod of embodiment.
Numeral among the figure:
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
According to Fig. 1, the sealed vacuum compression mod that the utility model provides, comprise cover half, dynamic model, and be arranged on ejecting mechanism on the dynamic model, form die cavity and overflow launder 14 after cover half and the dynamic model closure, die cavity is communicated with overflow launder 14, and the die joint arranged outside of cover half and dynamic model has between two circle sealing rings 11, the two circle sealing rings 11 and also is provided with the groove 12 of bleeding; Be provided with groove on the fixed half and moving half, after cover half and the dynamic model closure, groove forms many zigzag air discharge ducts 13, and the two ends of air discharge duct 13 are communicated with overflow launder 14 and the groove 12 of bleeding respectively, and compression mod is provided with the vacuum adapter 15 that is communicated with bleed groove 12 and evacuator.
The utility model is by arranging bleed groove 12 and the air discharge duct 13 that sealing ring and exhaust are used, treat by vacuum adapter 15 evacuator with after the groove 12 of bleeding is communicated with, evacuator can be extracted the gas in die cavity and the overflow launder 14 out by the air discharge duct 13 of zigzag, thereby bubble appears in the product of having avoided the casting forming process to cause.
Multiple modification to above-described embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.
Claims (4)
