Description
Technical field
The utility model relates to process structure used in a kind of filling sand technique, and in particular to a kind of conversion of sand core rod is hung
Hook device.
Background technique
When making sand core, traditional arbor suspension hook is embedded in sand core internal in advance, and after sand core molding, worker is according to estimating core
The molding sand of certain depth is dug up in the position of bone, finds lifting lug, after the completion of lower loam core, then the stop-off of lifting lug position.Due to various originals
Cause, stop-off area is big, and loose sand falls type chamber when stop-off is of poor quality or stop-off, and casting quality problem is caused to happen occasionally.Therefore it needs
Want one kind that can reduce stop-off area even without stop-off with effective position lifting lug position, it is ensured that stop-off quality improves production effect
Rate, the sand core rod provided convenience to production process control convert hook gear.The technical issues of prior art are as follows: arbor is fixed
Position trouble, stop-off quality problems are more.
Utility model content
Utility model aims to solve the above-mentioned prior art there are structures simple, the convenient arbor suspension hooks of conversion.
Solves arbor positioning trouble, the ropy problem of stop-off provides a kind of sand core rod conversion hook gear.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of sand core rod converts hook gear,
It is matched with sand core inner cavity, it is characterised in that: including arbor, arbor movable connecting rod and replacement head, the top of the arbor is set
It is equipped with protrusion, the outside of the protrusion is provided with screw thread, and fluted, the groove is arranged in the lower end of the arbor movable connecting rod
Inner wall on be also equipped with screw thread for being flexibly connected with arbor, the arbor is connect with arbor movable whorl, the arbor
The horizontal convex block convenient for connection is provided at the top of movable connecting rod, the replacement head includes handle part and connecting rod, described
It is fixedly connected at the top of connecting rod with the handle part, the bottom of the connecting rod is provided with lifting lug, the lifting lug and horizontal convex block
Match.The utility model first holds the location hole that the fixed core position of bone is set successfully in core mold inner cavity, when making sand core, first by core
In one insertion location hole of bone, resin sand is added, completes to sand core, after molding, backs out the movable connecting rod in sand core, uses
There are the replacement head of lifting lug, displacement activity connecting rod.After the completion of lifting by crane lower core, the replacement head of lifting lug is backed out, lifting lug hole is mended
Sand does not have to stop-off as needed.The device can greatly reduce stop-off workload, it is ensured that stop-off quality improves production effect
Rate provides convenience to production process control.
Preferably, the handle part is annulus.
Preferably, the convex cross section of the arbor top setting is circle.
Preferably, the sand core inner cavity offers the location hole for fixing arbor bottom, arbor bottom grafting
Enter positioning hole.
The substantial effect of the utility model is: the utility model, in core mold inner cavity, first holds the fixed core position of bone successfully and sets
Location hole, when making sand core, first by one insertion location hole of arbor, addition resin sand completes to sand core, molding
Afterwards, the movable connecting rod in sand core is backed out, with the replacement head for having lifting lug, displacement activity connecting rod.After the completion of lifting by crane lower core, twist
Under have the replacement head of lifting lug, do not have to stop-off to the stop-off of lifting lug hole or as needed.The device can greatly reduce stop-off work
Amount, it is ensured that stop-off quality improves production efficiency, provides convenience to production process control.
Detailed description of the invention
Fig. 1 is the integrally-built decomposition diagram of the utility model；
Fig. 2 is matched sand core inner cavity schematic diagram in the utility model.
In figure: 1, arbor, 2, arbor movable connecting rod, 3, replacement head, 4, protrusion, 5, horizontal convex block, 6, lifting lug, 7, sand core
Inner cavity, 8, location hole.
Specific embodiment
Below by specific embodiment, and in conjunction with attached drawing, the technical solution of the utility model is made further specifically
It is bright.
Embodiment 1:
A kind of sand core rod conversion hook gear (referring to attached drawing 1 and attached drawing 2), matches, including arbor with sand core inner cavity
1, arbor movable connecting rod 2 and replacement head 3, the top of the arbor are provided with protrusion 4, and the outside of the protrusion is provided with spiral shell
The lower end setting of line, the arbor movable connecting rod is fluted, is also equipped on the inner wall of the groove for movable with arbor
The screw thread of connection, the arbor are connect with arbor movable whorl, are provided at the top of the arbor movable connecting rod convenient for connection
Horizontal convex block 5, the replacement head includes handle part and connecting rod, at the top of the connecting rod with the handle part is fixed connects
It connects, the bottom of the connecting rod is provided with lifting lug 6, and the lifting lug matches with horizontal convex block.The handle part is annulus.It is described
The convex cross section of arbor top setting is circle.The sand core inner cavity 7 offers the location hole 8 for fixing arbor bottom, institute
It states the grafting of arbor bottom and enters positioning hole.
The present embodiment first holds the location hole that the fixed core position of bone is set successfully in core mold inner cavity, when making sand core, first by arbor
In one insertion location hole, resin sand is added, completes to sand core, after molding, backs out the movable connecting rod in sand core, with having
The replacement head of lifting lug, displacement activity connecting rod.After the completion of lifting by crane lower core, the replacement head of lifting lug is backed out, to the stop-off of lifting lug hole
Or stop-off is not had to as needed.The device can greatly reduce stop-off workload, it is ensured that and stop-off quality improves production efficiency,
It provides convenience to production process control.
Embodiment described above is a kind of preferable scheme of the utility model, is not made to the utility model any
Formal limitation, there are also other variations and modifications on the premise of not exceeding the technical scheme recorded in the claims.
