Further, said securing member also comprises a nut; First termination is provided with a stop nut hole, and stop nut hole and installing hole run through; Nut is fixedly mounted in the stop nut hole, and bolts and nuts are through being threaded, and bolt passes to push up behind the installing hole and is against on the cope cushion block.
Further, the cope cushion block is provided with groove, and the bolt lower surface is passed to push up behind the installing hole and is against in the groove.
Further, this groove is cylindrical, and this columniform bottom surface radius is greater than the external diameter of bolt; The bolt lower surface is passed to push up behind the installing hole and is against in the groove.
Further; The cope cushion block is formed by the extending to the outside that casts sandbox of sidewall protrusion of cope; The drag box cushion block is formed by the extending to the outside that casts sandbox of sidewall protrusion of drag box; Cope cushion block and drag box cushion block align each other, and cast the paired setting of sandbox die joint symmetrical, parallel relatively.
Further, it is arc that connector is, and connector also comprises the hammerlock that connects first termination and second termination.
Further, installing hole comprises internal thread, and bolt passes through being threaded to push up behind the installing hole and is against on the cope cushion block.
The utlity model has following beneficial effect: the locking mechanism of the casting sandbox of the utility model is connected fastening with the cope cushion block with the drag box cushion block through securing member by a connector and forms; Get final product with the light instrument tightening fastener parts in the operation; Do not knock vibrations, simple to operate; Locking mechanism is threaded, and coupling mechanism force is big, reliable lock.
Except top described purpose, feature and advantage, the utility model also has other purpose, feature and advantage.To do further detailed explanation to the utility model with reference to figure below.
Description of drawings
The accompanying drawing that constitutes the application's a part is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 is the locking mechanism sketch map of the casting sandbox of the utility model preferred embodiment.
The specific embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Please with reference to Fig. 1, the preferred embodiments of the utility model provides the locking mechanism of a casting sandbox, and casting sandbox 3 comprises cope cushion block 31 and drag box cushion block 32.Locking mechanism comprises: connector 2 and securing member 1, connector 2 is locked cope cushion block 31 and drag box cushion block 32 through securing member 1.
Connector 2 comprises first termination 21, connects the hammerlock 22 of first termination 21 and second termination 23 with 21 parallel second terminations 23 and, first termination, and the length of hammerlock 22 is slightly larger than the distance of cope cushion block 31 upper surfaces to drag box cushion block 32 lower surfaces.In this embodiment, connector 2 is arc body, and the integrally casting shaping, and is simple in structure.First termination 21 is provided with a stop nut hole 210 and installing hole 211.Wherein the center line of installing hole 211 is vertical with plane 230, and stop nut hole 210 connects with installing hole 211, and the side end face of first termination 21 is extended and run through in stop nut hole 210.
Securing member 1 comprises bolt 10 and and bolt 10 nut engaged 11.Nut 11 is fixedly mounted in the stop nut hole 210.Bolt 10 is inserted in the installing hole 211 from first end of installing hole 211, and with after nut 11 cooperates, and after second end of installing hole 211 passes, screws to the groove 310 of cope cushion block 31 again.Preferably, the groove 310 of cope cushion block 31 is cylindrical, and this columniform bottom surface radius is greater than the external diameter of bolt 10; More preferably; This columniform bottom surface radius is slightly larger than the external diameter of bolt 10, and in the present embodiment, the external diameter of bolt 10 is M20; At this moment, groove 310 is the cylindrical bore of diameter phi 24 dark 5cm.
In the process of carrying out sand casting, after cope and drag box cover each other, need this cope and drag box to be locked through the locking mechanism of the utility model.Detailed process is following: it is fixing earlier nut 11 to be put into stop nut hole 210, the upper surface of second termination 23 of connector 2 is pushed up with the plane 230 of drag box cushion block 32 each other support.
Guide effect through installing hole 211 is threaded bolt 10 with nut 11 again, limits bolt 10 displacement in the horizontal direction; Bolt 10 lower surfaces screw to the columniform groove 310 of cope cushion block 31, limit the displacement of bolt 10 vertical directions.Thereby; Locking mechanism elder generation holds out against the lower surface of drag box cushion block 32 through the upper surface of second termination 23 of connector 2; The bolt 10 that screws downwards again on first termination 21 comes fastening to cast the cope cushion block 31 and drag box cushion block 32 of sandbox 3, reaches the purpose of locking.
The locking mechanism of this casting sandbox is through the locking that is threaded of bolt 10 and nut 11, shockproof, coupling mechanism force greatly, reliable lock.In manipulating, only need tight a bolt with light instrument 10 gets final product, easy and simple to handle.In addition, between the bolt 10 of securing member 1 and nut 11, cooperate and stripped thread occurs, perhaps, when the thread failure of bolt 10 or nut 11, take out bolt 10 or nut 11 and change, need not to change whole connector, thereby reduce cost; And securing member 1 is standard component, and interchangeability is good.
In other embodiments, the installing hole 211 on first termination 21 also can be made as screwed hole, and securing member 1 is a bolt 10, and bolt 10 direct and installing hole 211 threaded engagement need not nut.
In other embodiments, first termination 21 and second termination 23 can switching fabrics.
In other embodiments, second termination 23 can be set to identical thread connecting mode with first termination 21.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
