Abstract
The utility model discloses a tool used for replacing a flask positioning pin bush, which comprises iron hooks, a limiting rack, a pressure unit and an inserted pin, wherein, the iron hooks are arranged symmetrically, the limiting rack is connected with the iron hooks in a detachable manner, and iron hook bending parts are matched with the bottom part of the flask positioning pin bush; and the pressure unit is propped against the limiting rack and used for drawing the limiting rack so as to drive the iron hooks to take the flask positioning pin bush out. Iron hook through-holes are formed on the opposing sides of the iron hooks and the iron hook bending parts; the limiting rack is U-shaped, and limiting rack through-holes are symmetrically formed at U-shaped free ends; and the inserted pin penetrates through the limiting rack through-holes and the iron hook through-holes so as to achieve the above-mentioned detachable connection. By adopting the tool, only one man is needed when the pin bush is replaced without the help of auxiliary facilities such as a crane and the like, so that the flask positioning pin bush can be rapidly replaced in a molding line, and time and labor can be saved.
Description
Technical field

Background technology
In casting field, flask bushing belongs to precision component, is used with mould alignment pin and mould assembling alignment pin, is the main means that guarantee that foundry goods appearance and size adheres to specification, therefore must be to its regular detection, and wear extent in time changed greater than the set pin sleeve of tolerance.Owing to adopt interference fit when set pin sleeve and sandbox assembling, be difficult to take out after installing.The method that changes set pin sleeve at present is as follows: at first will hang out sandbox with crane, be placed on the level land sandbox is edge-on then, beat drill rod and take out set pin sleeve with iron hammer at last, be 17 minutes the average time of changing a set pin sleeve in this way, need two people operation, one one in crane, one of hoistman, therefore both there had been unsafe factor in operation, wasted time and energy again.
The utility model content
The utility model is in order to overcome defective in the above-mentioned prior art, to need not to use crane, is detachable flask bushing by the extracting tool one man operation.
The instrument of replacing flask bushing of the present utility model comprises symmetrically arranged cleek and the restriction frame that removably connects with cleek, and the bottom of cleek bend and flask bushing is suitable; Also comprise pressure apparatus, pressure apparatus connects with the restriction frame, drives cleek taking-up flask bushing thereby be used for tractive restriction frame.
Wherein, on the cleek, a relative side of cleek bend is established the cleek through hole; The restriction frame is the U type, and U type free end is symmetrical arranged restriction frame through hole; Also comprise latch, latch runs through and is arranged in restriction frame through hole and the cleek through hole.
Preferably, the width of cleek bend is greater than the flask bushing bottom width; Cleek length is greater than the height of flask bushing.
Preferably, setting prevents the parallels that cleek moves between the symmetrically arranged cleek; Parallels can be the L type.
Wherein, also comprise the sleeve that is used to support described pressure apparatus, the sleeve cross section is the U type, and sleeve is positioned at restriction frame bottom, and is sleeved on the cleek outside, and latch runs through in the groove that is arranged at sleeve; Pressure apparatus can be jack.
Compared with prior art, use the utility model to change the instrument of guide, only need the one man operation during replacing, and need not by auxiliary equipment such as cranes, can change flask bushing fast on mo(u)lding line, the operating time is short, and is time saving and energy saving.

The specific embodiment
Below in conjunction with accompanying drawing, a 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.
To shown in Figure 5, the instrument of replacing flask bushing of the present utility model comprises two cleeks 1 as Fig. 1, and cleek one end is established bend 11, and the other end is square, and projected square part central authorities establish cleek through hole 12; Also comprise L shaped parallels 2; And sleeve 3, establish the sleeve groove 31 of perforation in the middle of the sleeve; U type position-limited rack 4, two free ends of position-limited rack are established position-limited rack through hole 41; Also has a columniform latch 5.The annexation of above-mentioned each parts following (as shown in Figure 6): the bottom of cleek bend and flask bushing is suitable, be used to hook the bottom of guide, the width of cleek bend is slightly larger than flask bushing bottom width (being the guide wall thickness), and cleek length is greater than the height of flask bushing.Hook back, guide bottom move left and right for fear of cleek, the parallels 2 of L type is set between symmetrically arranged cleek.Latch 5 runs through and is arranged in restriction frame through hole 41 and the cleek through hole 12, realizes removably connecting of restriction frame and cleek.For realizing mechanical stretch, also comprise pressure apparatus in the instrument of the present utility model, promptly jack 6, and jack connects with restriction frame 4 during use, takes out flask bushing 7 thereby be used for tractive restriction frame drive cleek 1.Jack is arranged on and is used to support on the jack sleeve 3, and sleeve is positioned at restriction frame bottom, and is sleeved on the cleek outside, and the sleeve cross section is the U type, and after the installation, latch 5 runs through and is arranged in the sleeve groove 31.
When replacing flask bushing instrument of the present utility model was installed, in the gap between the flask bushing 7 of at first two cleeks 1 being packed into, the cleek bend toward the outer side and the bottom of hooking flask bushing 7; Between cleek, fill in parallels 2 then, prevent that cleek from moving; Again latch 5 is penetrated restriction frame free-ended restriction frame through hole 41 and cleek through hole 12, thereby limited the relative motion of cleek with restriction frame in the vertical direction; Add stop sleeve 3; At last jack is positioned between stop sleeve and the restriction frame.Press jack stand restriction frame like this, take up cleek, cleek hooks the guide bottom, until guide is extracted.
The instrument of replacing flask bushing of the present utility model can be changed flask bushing fast on mo(u)lding line, the operating time is short, and is time saving and energy saving, has tangible economic worth.Only need operating personnel to finish when changing set pin sleeve, do not need auxiliary equipment such as crane, and only use about 1.5 minutes the average time of changing a set pin sleeve.
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.
