Abstract
The utility model discloses a push rod device of die casting mold, which comprises a push rod that is sleeved with a push rod sealing assembly with a step. The contact surface between the push rod sealing assembly and the push rod is provided with at least one first sealing groove. The sealing groove is provided with a first sealing ring. The step is provided with at least one second sealing groove. The sealing groove is internally provided with a second sealing ring. After the push rod device of the utility model is installed to an installation position which is matched with the sealing assembly and is provided on a movable mold sleeve plate, the sealing assembly is fixed with a push rod sealing plate for restricting in the installation position. A clearance between the push rod and a push rod h ole is totally sealed through the sealing rings in the first sealing groove and the second sealing groove. The entering of gas into the chamber of die casting mold through the push rod opening can be effectively prevented thereby improving casting quality.
Description
Technical field
The utility model relates to the pin-lift arrangement in a kind of compression mod.
Background technology
In extrusion process, the foundry goods of compression mod dynamic model demoulding aftershaping need eject it with the push rod that is arranged on the dynamic model, with convenient foundry goods is taken off.Wherein, many push rods pass the jogger hole that is positioned on dynamic model cage plate and the moving die insert, and are concordant with cavity surface.But, seal by simple heat resistant joint ring between employed push rod and the cover half cage plate in compression mod at present, its sealing effectiveness is relatively poor, and ambient atmos is easy to enter into by this sealing surface the die cavity of vacuum, cause foundry goods to produce pore, shrinkage cavity, have a strong impact on casting quality.In addition, for the ease of push rod action smoothly in cover half cage plate and fixed die insert, this ring structure is high to the position degree requirement of jogger hole, has strengthened the mould manufacture difficulty so virtually.
The utility model content
In order to solve the above problems, it is a kind of simple in structure that the purpose of this utility model is to provide, and can effectively seal, and reduces the compression mod pin-lift arrangement of Mould Machining difficulty.
The technical scheme that the invention for solving the technical problem adopted is:
A kind of compression mod pin-lift arrangement, comprise push rod, be socketed with a push rod black box on the described push rod with step, the contact-making surface of described push rod black box and push rod is provided with at least one first seal groove, described seal groove is provided with first sealing ring, described step is provided with at least one second seal groove, is provided with second sealing ring in the described seal groove.
The beneficial effects of the utility model are: with pin-lift arrangement of the present utility model pack into black box suitable be arranged on installation position on the dynamic model cage plate after, with the push rod sealing plate black box is fixed again, be limited in the installation position, by the sealing ring that is arranged in first, second seal groove the gap between push rod and the jogger hole is sealed fully, can prevent effectively that gas from entering into the compression mod die cavity by jogger hole, thereby improve casting quality.In addition on the one hand, after black box of the present utility model is put into the lower installation position of positional precision, can there be the position adjustment of certain interval its periphery and installation position, thereby can make that push rod moves smoothly in jogger hole, assurance ejects normally carrying out of operation, therefore, can greatly reduce the position degree requirement in mould dynamic model cage plate and moving die insert upper ejector pin hole, thereby reduce the accuracy of manufacture of mould, reduce cost.
As improvement of the technical scheme, described first seal groove is provided with two.Stressed like this than balance, good sealing effect.
As further improvement in the technical proposal, described second seal groove is provided with one.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model compression mod pin-lift arrangement structural representation;
Fig. 2 is the utility model compression mod pin-lift arrangement user mode schematic diagram;
Fig. 3 is the utility model compression mod pin-lift arrangement user mode enlarged diagram.
The specific embodiment
With reference to Fig. 1, a kind of compression mod pin-lift arrangement of the present utility model, comprise push rod 1, be socketed with a push rod black box 3 on the described push rod 1 with step 2, described push rod black box 3 is provided with at least one first seal groove 31 with the contact-making surface of push rod 1, described seal groove 31 is provided with first sealing ring 4, and described step 2 is provided with at least one second seal groove 32, is provided with second sealing ring 5 in the described seal groove 32.
In conjunction with Fig. 2 and Fig. 3, with pin-lift arrangement of the present utility model pack into black box 3 suitable be arranged on installation position 12 on the dynamic model cage plate 11 after, with push rod sealing plate 13 that black box 3 is fixing again, be limited in the installation position 12, by the sealing ring that is arranged in first, second seal groove 31,32 gap between push rod 1 and the jogger hole 10 is sealed fully, can prevent effectively that gas from entering into the compression mod die cavity by jogger hole 10, thereby improve casting quality.In addition on the one hand, after black box 3 of the present utility model is put into the lower installation position of positional precision 12, can there be the position adjustment of certain interval its periphery and installation position 12, thereby can make push rod motion in jogger hole 10 smoothly, assurance ejects normally carrying out of operation, therefore, can greatly reduce the position degree requirement in mould dynamic model cage plate 11 and moving die insert 14 upper ejector pin holes 10, thereby reduce the accuracy of manufacture of mould, reduce cost.
In the present embodiment, second seal groove 32 is arranged on the step 2, and is not arranged on the top of black box, and this is because the top portion area is too little, does not have enough installed surfaces, is unfavorable for the installation of sealing ring.And step 2 places have bigger self adaptation adjustment space, can effectively reduce the position degree precision in dynamic model cage plate 11 upper ejector pin holes 10, reduce manufacturing cost.
As preferably, described first seal groove 31 is provided with two.Stressed like this than balance, good sealing effect.
As preferably, described second seal groove 32 is provided with one, can match according to actual conditions a plurality of, to satisfy the demand.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
