Abstract
The utility model discloses a box expansion prevention device for a casting sand box, which is characterized in by comprising a door clamp, a clamp sleeve and a wedge; the key design of the utility model includes that in the prior art, the deformation generated by the expansion and retraction of a casting is only resisted by the strength of the sand box, when the box expansion prevention device is used in conjunction with the casting sand box, the sand box becomes firmer and is prevented from having deformation, and the box expansion prevention function is realized through the coordination of the door clamp, the clamp sleeve and the wedge, and the sand box.
Description
Technical field
The utility model relates to the structure of the anti-swell device of a kind of foundry goods sandbox.
Background technology
The swell phenomenon usually takes place because of foundry goods sandbox insufficient strength in more existing high heavy castings when Foundry Production, for this problem of foundry goods sandbox swell, normally by aspects such as foundry goods sandbox structure, material are changed the intensity that increases the foundry goods sandbox, sandbox Heavy Weight and cost height so just may appear, effect can not reach problems such as expection. when cast casting, need address these problems, this just needs the special version of design to strengthen the intensity of foundry goods sandbox, the requirement when satisfying cast casting.
Summary of the invention
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of more effectively structure solution.The anti-case apparatus that rises of a kind of foundry goods sandbox is characterized in that comprising badge, cutting ferrule and chock.
The utility model is made up of badge, cutting ferrule, chock, and its each parts are referring to Fig. 1.
The technical solution adopted in the utility model is such: key Design of the present utility model is to change original in aspects such as foundry goods sandbox structure, material being changed the mode of the intensity that increases the foundry goods sandbox, now a kind of device and sandbox are used, increase the purpose that foundry goods sandbox intensity reaches anti-swell.The realization of anti-swell is earlier cutting ferrule to be put, and the foundry goods sandbox is put in the groove scope of cutting ferrule (referring to Fig. 2), badge is cooperated with cutting ferrule again, with chock the gap of badge and cutting ferrule gap, badge and sandbox is filled up fixing (referring to Fig. 3) at last.Because of the present utility model be absolute construction, reusable, can be used on the non-same foundry goods sandbox, low to foundry goods sandbox self requirement of strength, this just can solve foundry goods sandbox Heavy Weight, problem that cost is high.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are: resolved foundry goods sandbox Heavy Weight, cost height, prevented that the swell effect can not reach the problem of expection.
Description of drawings
Fig. 1 is the whole formation of the utility model.
Fig. 2 is cutting ferrule and foundry goods sandbox fit form.
Fig. 3 is the fit form of the utility model integral body and foundry goods sandbox.1-1 is a badge among Fig. 1; 1-2 is a chock; 1-3 is a cutting ferrule; 2-1 is the foundry goods sandbox among Fig. 2; 2-2 is a cutting ferrule; 3-1 is the foundry goods sandbox among Fig. 3; 3-2 is a cutting ferrule; 3-3 is a chock; 3-4 is a badge.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As Fig. 2, shown in Figure 3, key Design of the present utility model is the independence and the conformability of cutting ferrule and badge, groove above the cutting ferrule plays position-limiting action to the foundry goods sandbox, can guarantee the cooperation of cutting ferrule and badge like this, specially designed chock can fill up the gap of badge and cutting ferrule gap, badge and sandbox fixing, so just can reach the purpose of anti-swell.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
