Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide the mechanical vacuum valve on a kind of die casting mould, initiatively extracts mould intracavity gas, reduces gas in press casting procedure and is involved in aluminium liquid, improve the quality of pack alloy product.
To achieve these goals, vacuum valve on a kind of die casting mould designed by the utility model, comprise valve body, described valve body is provided with valve pocket, be provided with in described valve pocket and can move left and right together with described valve body or the spool of relative movement, space is left between this spool and valve pocket inwall, described spool right-hand member is exposed to outside valve body, described spool right-hand member and described valve pocket right-hand member suitable, thus the relative valve body of spool is turned left move a certain distance back valve core right-hand member to seal with valve pocket right-hand member to abut, described valve body is connected with driving mechanism, described valve body is provided with the vacuumizing joint be connected with valve pocket, this vacuumizing joint is connected with vacuum machine.
Described valve pocket runs through two ends, valve body left and right, described valve body left end is connected with back seat, described back seat is connected with driving mechanism and is provided with guide sleeve between this back seat and valve body, described guide sleeve left end is provided with push rod, described push rod can move left and right with valve body, and on the deformation trace of described push rod, be provided with valve core reset block, described spool is through guide sleeve and push rod, the part that described spool is located in guide sleeve is provided with annular groove, this annular groove contacts with steel ball, be provided with groove in described guide sleeve, be provided with spring in described groove, described spring and steel ball abut against.
Described push rod two ends pass back seat, and described valve core reset block is positioned on this die casting mould.
Described annular groove right side wall is obliquely installed to away from annular groove direction.
Described spool right-hand member is provided with the first inclined-plane, and the outward-dipping setting from left to right of this first inclined-plane, described valve pocket right-hand member is provided with second inclined-plane suitable with the first inclined-plane.
Described driving mechanism is oil cylinder.
Vacuum valve on a kind of die casting mould that the utility model obtains, its technique effect is: initiatively extract the gas in die casting mould die cavity out by vacuum machine, reduce the formation of interiors of products pore, improve interiors of products quality, reduce die casting scrappage, reduce costs, and this vacuum valve is simple to operate, change easy maintenance, structural stability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is another structural representation of the present utility model.
Fig. 3 is the A place partial enlarged drawing of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1-2, vacuum valve on a kind of die casting mould that the utility model provides, comprise valve body 1, valve body 1 is provided with and runs through its two ends, left and right valve pocket 2, valve body left end is installed with guide sleeve 3 and back seat 4 successively, and back seat 4 is connected with driving mechanism 5, and the driving mechanism 5 in the present embodiment is oil cylinder, under the drive of oil cylinder, valve body 1, guide sleeve 3 and back seat 4 can be made to move left and right together.
Be provided with in valve pocket 2 and can move left and right together with valve body 1 or the spool 6 of relative movement, space is left between spool 6 and valve pocket inwall, spool 2 right-hand member is exposed to outside valve body 1, spool right-hand member and valve pocket right-hand member suitable, thus the relative valve body of spool is turned left move a certain distance back valve core right-hand member to seal with valve pocket right-hand member to abut, valve body 1 is provided with the vacuumizing joint 7 be connected with valve pocket 2, and this vacuumizing joint 7 is connected with vacuum machine.
Wherein, spool right-hand member is provided with the first inclined-plane 14, first inclined-plane is outward-dipping setting from left to right, and valve pocket right-hand member is provided with second inclined-plane 15 suitable with the first inclined-plane, thus the relative valve body of spool is turned left move a certain distance back valve core right-hand member to seal with valve pocket right-hand member to abut.
Guide sleeve 3 left end is provided with push rod 8, push rod 8 two ends pass back seat 4, thus push rod 4 can be moved left and right with valve body, and on the deformation trace at push rod two ends, be provided with valve core reset block 9, valve core reset block is positioned at both sides before and after back seat and is positioned on die casting mould, spool 2 is through guide sleeve 3 and push rod 8, spool 2 part be located in guide sleeve 3 is provided with annular groove 10, annular groove 10 right side wall is obliquely installed to away from annular groove direction, annular groove contacts with steel ball 11, groove 12 is provided with in guide sleeve 3, spring 13 is provided with in groove 12, spring 13 and steel ball 11 abut against, as shown in Figure 3, spool 2 in figure is in toward in moving left.
The use principle of this vacuum valve: during aluminium liquid enters die cavity from material pipe, vacuum machine is in the state of bleeding always, gas enters the space formed between valve pocket right-hand member and spool from the bypass channel of cavity, and extracted out by vacuum machine, aluminium liquid impacts spool right-hand member and promotes spool 2 toward moving left under effect of inertia, thus making spool right-hand member contact with valve pocket right-hand member and stop gas to flow into space, spool closes interruption of bleeding.Because spool is toward moving left, steel ball 11 and spool periphery are abutted against, thus spool can move left and right together with guide sleeve 3.After die sinking, oil cylinder pulls back seat 4 toward moving left, and drives guide sleeve, push rod 8, spool and valve body 1 together toward moving left, when ram impacts valve core reset block 9, spool obtains a power to the right, under this force, toward moving right, steel ball is made to be positioned at annular groove 10, thus spool is not moved together with guide sleeve, spool is turned right and is returned to original position, takes out cast product simultaneously, valve body is blown and is removed aluminium bits, and before matched moulds, oil cylinder pushing valve body gets back to original position.
