Description

A kind of split type push rod for casting mould

Technical field

The utility model is related to casting technology field, more particularly to a kind of split type push rod for casting mould.

Background technology

Low-pressure casting hub die is mainly made up of three parts：Backform (including frock), side mould (including frock) and bed die (including frock) is constituted.Continuous for the ease of production, after single cycle production terminates, backform takes blank out of, the hair under push rod top Base, pallet takes blank away.Need to set push rod in a mold for this.Traditional mould is as shown in Figure 1.Specifically, Fig. 1 is shown The position of one of them big push rod.

Traditional ejector pin of die set is integral type, and its structure is as shown in Figure 2.Ejector pin of die set, which is set, meets following rule：1. it is interior It is small push rod, generally 12 at wheel rim；2. flange is big push rod, generally 5~8 (lower Fig. 1 is big push rod position).

In continuous flow procedure, mould is 5-6 order of classes or grades at school (8 hours dutys) by the working life of full maintenance, This rear mold needs progress to unload the goods from the airplane maintenance, wherein repairing and changing big push rod for part and parcel.The replacing of big push rod have with Lower two shortcomings：1. big push rod typically needs more to renew push rod using 15 order of classes or grades at school or so, and conventional big push rod is integrated push rod, more It is overall discarded after changing, cause cost to waste；2. step is when big push rod is changed：Dismantle mandrel plate, dismounting push rod upper plate and push rod The bolt (generally 14-18) of plate connection, push rod upper plate is removed, big push rod is removed and changes, push rod upper plate is installed, installation 14-18 bolts are finished.Complex steps and there is serious potential safety hazard.

At the same time, inventor the analysis found that, the failure of big push rod is mainly due to push rod taper end and contacting dies Friction, and due to gap therebetween, can there is a situation where to press from both sides aluminium, cause push rod to be pulled, the situation that stretch bending is even broken.

Utility model content

The purpose of this utility model is, simplifies big push rod exchonge step, reduces potential safety hazard, reduces cost.

In one side of the present utility model there is provided a kind of split type push rod for casting mould, it is thick by push rod End (1), push rod taper end (3) are constituted, and are connected through a screw thread between described push rod butt end (1) and push rod taper end (3), its feature It is：Include jackscrew (2) on the side wall of described push rod butt end (1), described jackscrew (2) passes through the side wall of push rod butt end (1) And end holds out against push rod taper end (3).

In terms of the utility model is preferred, the threaded connection between push rod butt end (1) and push rod taper end (3) is M12* 1.25 threaded connection.

In terms of the utility model is preferred, the mode that described jackscrew (2) is connected through a screw thread is fixed to push rod butt end (1)。

In terms of the utility model is preferred, the screw thread between described jackscrew (2) and push rod butt end (1) is M2*0.2 spiral shells Line.

In terms of the utility model is preferred, the side of push rod butt end (1) and push rod taper end (3) includes the flat of spanner clamping Face part.

In terms of the utility model is preferred, the overall diameter of described push rod butt end (1) is 18-25mm, push rod taper end (3) Overall diameter be 10-15mm.

In terms of the utility model is preferred, the overall diameter of described push rod butt end (1) is 20mm, push rod taper end (3) Overall diameter is 12mm.

In one side of the present utility model, described push rod is big push rod.

Of the present utility model in terms of other, following utility model design is employed：

(1) in order to simplify the exchonge step of big push rod, and cost is reduced, by big push rod butt end (diameter 20mm) and taper end (diameter 12mm) is separated, and by being threadedly coupled (M12*1.25), push rod failure need to only change taper end, the repeatable profit of butt end With See Figure 3 is push rod installation diagram, and See Figure 4, Fig. 5 are the butt end and taper end of push rod；

(2) in production process, push rod needs axially to move back and forth, it is contemplated that have the possibility of absent-mindedness, Gu Luowenchu increase jackscrews (M2*0.2), See Figure 6 is jackscrew；

(3) for the ease of dismounting push rod using instrument, butt end and taper end increase the spanner retained part of one fixed width.

The technical solution of the utility model brings following advantageous effects：

(1) novel separated push rod is come into operation, and dismounting push rod 14~18, top bolt can be reduced and tear open by changing big push rod The step of filling push rod upper plate；

(2) novel separated push rod comes into operation, and can reduce the use of overhead traveling crane twice and its suspender, reduces potential safety hazard；

(3) push rod taper end need to be only changed when the novel separated push rod is changed, push rod butt end is reusable, reduces into This.
