Abstract
The utility model discloses a disassembling tool for a sand box positioning pin bush, comprising a traction assembly used for drawing the sand box positioning pin bush, a pressure device applying force on the traction assembly, and a support part used for supporting the pressure device. Compared with the prior art, the disassembling tool has the advantages that the structure is simple, the use is convenient, the quick and convenient disassembly of the sand box positioning pin bush on a molding line by only one worker is realized, and the work efficiency can be improved greatly.
Description
Technical field
The utility model relates to a kind of extracting tool, relates in particular to a kind of flask bushing extracting tool that is used for casting field.
Background technology
In casting field, flask bushing matches with mould alignment pin and mould assembling alignment pin, adheres to specification to guarantee foundry goods appearance and size.The flask bushing required precision is very high, in use must regularly detect, and change the set pin sleeve of wearing and tearing greater than tolerance.Because set pin sleeve and sandbox are interference fit during assembling, be difficult to set pin sleeve is disassembled.The dismounting of set pin sleeve mainly is in the prior art, at first with crane sandbox is hung out and edge-on being placed on the level land, beats drill rod with iron hammer then set pin sleeve is taken out.Such method needs many people to cooperate, and must use big machinery such as crane, wastes time and energy, and has many unsafe factors.
The utility model content
The utility model is in order to overcome above-mentioned defective of the prior art, a kind of simple in structure and easy to operate flask bushing extracting tool to be provided.
Flask bushing extracting tool described in the utility model comprises the pull element of flask bushing that is used to choose, to the pressure apparatus of pull element applied thrust and the support component of abutment pressure device.
Preferably, described pull element comprises restriction frame and cleek, described restriction frame is the U-shaped bar, the two ends of this U-shaped bar are respectively arranged with restriction frame through hole, one end of described cleek is established bend, the other end is provided with the cleek through hole, passes described restriction frame through hole and the cleek through hole will limit frame and cleek couples together with a latch.
Preferably, described pressure apparatus is a jack.
Preferably, described support component is the tub that an end seals an end opening, and the bucket wall is provided with a cross-notching, is used to hold latch.
Preferably, this flask pin extracting tool also comprises a parallels, when using the flask bushing extracting tool, described parallels plug is between two cleeks, prevent that cleek from coming off from set pin sleeve, simultaneously a cross-notching is set on described support component, be used to hold this parallels.
Compared with prior art, this extracting tool is simple in structure, and is easy to use, only needs a staff just to can be implemented in and dismantles flask bushing on the mo(u)lding line quickly and easily, can greatly increase work efficiency.

The 1-cleek, the 2-parallels, the 3-sleeve, 4-limits frame, 5-latch, 6-jack, 7-flask bushing, 11-bend, 12-cleek through hole, 31-sleeve groove, 41-restriction frame through hole.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of the specific embodiment.
Shown in Fig. 1-A and Fig. 1-B, this flask bushing extracting tool comprises by limiting pull element, sleeve 3 and the jack 6 that frame and latch and cleek are formed.Jack 6 is a pressure apparatus, and under the support of support component sleeve, jack applies a thrust that makes progress to the restriction frame 4 of pull element, and the restriction frame drives cleek 1 flask bushing 7 is extracted.
Shown in Fig. 4-A and 4-B, restriction frame 4 is a U-shaped bar, and the two ends of U-shaped bar are respectively arranged with restriction frame through hole 41.Shown in Fig. 2-A and 2-B, the main body of cleek 1 is lath-shaped, the one end is provided with cleek through hole 12, the other end is provided with bend 11, the bottom of bend shape and socket is adaptive, be used to hook the bottom of guide, the width of cleek bend is slightly larger than the width of flask bushing bottom, and the length of cleek is greater than the width of guide.Use a latch 5 to pass, thereby cleek and restriction frame are coupled together the composition pull element from described cleek through hole 12 and restriction frame through hole 41.
Described sleeve is a support component.This sleeve is the cylinder that an end seals an end opening, and a bucket wall is provided with two cross-notchings, a pair ofly is used to hold latch 5, a pair ofly is used for holding where necessary parallels 2.
When using present embodiment flask bushing extracting tool, in the gap between the flask bushing of at first two cleeks being packed into, the bottom of the bend hook flask bushing of cleek; Between cleek, fill in parallels then, prevent that cleek from moving; Pass restriction frame through hole and cleek through hole with a latch again, will limit frame and cleek couples together; Again sleeve is inserted in latch and lid and places the cleek top; Jack is placed in above the sleeve, and the restriction frame is withstood in the upper end of jack; Press jack, this moment, jack applied a thrust that makes progress to the restriction frame under the support of sleeve, and the restriction frame drives cleek alignment pin is extracted.
Compared with prior art, the utility model is simple in structure, and is easy to use, only needs a staff just to can be implemented in and dismantles flask bushing on the mo(u)lding line quickly and easily.
More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
